Medivir announces interferon-free phase IIa trial with HCV PI plus investigational non-nuc...

Press release  posted 9/20 on PR Newswire. Medivir announces a Phase IIa trial pairing it's HCV NS3/4A protease inhibitor simeprevir (TMC435) with Janssen's non-nuc TMC647055 and ritonovir (a potent CYP P450 inhibitor) with and without ribavirin in treatment naive, relapser genotype 1 patients as well as the difficult-to-treat genotype 1a null responder population. The latter population is incredibly important, as the efficacy with current anti-HCV regimens is notoriously low. The addition CYP P450 inhibitor ritonavir is used in regimens to block metabolism of the active molecule(s) leading me to believe that TMC435 may effect the drug levels of TMC647055, or both. Ritonavir, unfortunately, also limits concomitant meds also metabolized by CYP P450.  

A Phase IIa Interferon Free Combination Hepatitis C Trial of Simeprevir (TMC435) and TMC647055 Will Commence Shortly

STOCKHOLM, September 20, 2012 /PRNewswire/ --
Medivir AB (OMX: MVIR), announced today that simeprevir (TMC435) and TMC647055, a non-nucleoside inhibitor (NNI) will enter a phase IIa interferon free combination trial.

Simeprevir is a once daily potent HCV NS3/4A protease inhibitor in phase III clinical development for the treatment of chronic hepatitis C jointly developed by Medivir and Janssen Research & Development Ireland (Janssen). TMC647055 is a potent NNI (non-nucleoside inhibitor) of the HCV NS5B polymerase and is being developed by Janssen R&D.

"This study is in line with Medivir's and Janssen's strategy to evaluate different combination possibilities with simeprevir for interferon-free HCV treatments. This will broaden our understanding of simeprevir, which we believe has the necessary characteristics to potentially become a key component of future hepatitis C treatment regimens, including combination with interferon and ribavirin as well as interferon-free therapies," comments Charlotte Edenius, Medivir's EVP of Research and Development.

Study design
This will be an open label study in patients who are chronically infected with HCV genotype-1a or 1b to assess the efficacy, safety and tolerability of the combination. The primary endpoint in the study will be SVR12 (sustained virologic response 12 weeks after end of treatment). Simeprevir, TMC647055 and low-dose ritonavir will be co-administered once daily, with and without ribavirin.

Approximately 40 patients will be enrolled in this study, which is divided in two parts. The first part will include patients chronically infected with HCV genotype-1, who are either treatment-naive or have relapsed after prior pegylated interferon (PegIFN)/ribavirin treatment. The treatment will consist of simeprevir, TMC647055 and low-dose ritonavir, with and without ribavirin for 12 weeks.

The second part of the trial will investigate the same regimen in prior null responder patients chronically infected with HCV genotype 1a.

Additional information about this study will be posted on http://www.clinicaltrials.gov

Bristol-Myers Squibb and Medivir/J&J expand on Direct Acting Antiviral agreement...

Posted on 4/18/12 on Bloomberg.com - A good day for Medivir/J&J's late stage HCV protease inhibitor TMC435 as both companies inked a deal with BMS looking at mixing and matching Direct Acting Antivirals with TMC435 in interferon-free regimens for treating chronic Hepatitis C. Expect to see more data on both TMC435 and BMS's arsenal of DAA's this week from EASL. 

Bristol-Myers Expands Hepatitis C Accord With J&J, Medivir
By Makiko Kitamura - Apr 18, 2012 5:27 AM PT

Bristol-Myers Squibb Co. (BMY) agreed to conduct two trials of experimental hepatitis C treatments in collaboration with Medivir AB (MVIRB) and Johnson & Johnson. (JNJ) Medivir shares rose as much as 5.7 percent in Stockholm.

The companies will conduct a late-stage trial of Bristol- Myers’ daclatasvir and J&J and Medivir’s TMC435, depending on the outcome of a mid-stage study, Stockholm-based Medivir said today in a statement. A drug interaction study of TMC435 with Bristol-Myers’ BMS-986094 will also be conducted, they said. That expands a collaboration between J&J and Bristol-Myers announced Dec. 2, Medivir said.

The Bristol-Myers drug in the second study entered the company’s pipeline with the acquisition of Inhibitex Inc. for $2.5 billion in February. TMC435 is a protease inhibitor, which blocks the action of the protease enzyme the hepatitis virus needs to replicate, directly stopping it from spreading. BMS-986094 is a nucleotide polymerase inhibitor, which works differently to block the virus’ ability to replicate in the body.

“We see the expanded clinical collaboration as a strong validation of TMC435, especially as we know of no other competing protease inhibitors running interferon-free combination trials with other direct-acting antivirals externally,” which include polymerase inhibitors, said Hans Jeppsson, an analyst at Danske Bank, in a note to investors today.

Medivir shares rose 4.6 percent to 73.25 kronor at 2:17 p.m. in Stockholm, giving the company a market value of 2.29 billion kronor ($339 million).

Drug Combinations
Other nucleotide polymerase inhibitors include Gilead Sciences Inc.’s 7977 compound, which was gained through the company’s acquisition of experimental hepatitis C-treatment maker Pharmasset Inc. for $10.8 billion in November. Bristol- Myers, based in New York, and Medivir are also testing their experimental treatments in combination with Gilead’s 7977.

Drugmakers are exploring cocktails of hepatitis C treatments that exclude interferon, a component of the current standard of care, because of the injectable therapy’s side effects.

Hepatitis C affects as many as 170 million people globally, putting them at risk of developing liver cancer, according to the World Health Organization. The disease is most commonly transmitted through contaminated blood transfusions, organ transplants, contaminated syringes and needle-injected drug use, according to the WHO.

TMC435 going head-to-head with Telaprevir in Phase III study...

Press release posted 3/13/12 on Medivir.com. Viral Matters editor comments: Medivir is feeling pretty confident in it's HCV protease inhibitor TMC435, so confident that the company has commenced in screening patients for a head-to-head Phase III 744 patient genotype 1 null and partial responder trial vs Telaprevir + P/R. This trial should give everyone a clearer picture on TMC435's efficacy in this difficult-to-treat population vs the new Standard of Care. Pretty gutsy. I like it. 

Medivir announces new studies in phase III program for TMC435

13-Mar-12
· Study in previous non-responder Hepatitis C genotype-1 infected patients
· Study in Hepatitis C genotype-4 infected patients

Huddinge, Sweden – MedivirAB (OMX: MVIR) a research based specialty pharmaceutical company focused on infectious diseases announces that its oral, once daily investigational protease inhibitor TMC435, developed by Janssen Pharmaceuticals for the treatment of Hepatitis C virus (HCV), has commenced patient dosing and started screening in two new phase III clinical trials, HPC3001 and HPC3011, respectively.

HPC3001
HPC3001 is a phase III efficacy, safety and tolerability study comparing TMC435 versus telaprevir, each in combination with Pegylated Interferon α-2a (PegINF) and ribavirin (RBV), in hepatitis C genotype-1 infected patients who were null or partial responders to prior PegINF/RBV therapy. The study which is a randomized, double-blind, double-dummy, two-arm study is targeted to enroll 744 patients.

The aim of the study is to demonstrate the efficacy of TMC435 based therapy compared to the approved telaprevir regimen in this difficult to treat population.

Patients will receive TMC435 150 mg once daily or telaprevir 750 mg administered every eight hours (q8h) in combination with PegINF/RBV for 12 weeks followed by 36 weeks of PegIFN/RBV alone. The primary endpoint of the study is sustained virological response at 12 weeks (SVR12).

HPC3011
HPC3011 is an open label, single arm phase III trial to explore the efficacy, safety and tolerability of TMC435 150 mg once daily, in combination with PegIFN/RBV in 100 treatment naïve or treatment experienced, Hepatitis C genotype-4 infected patients.

Current standard of care treatment for chronic HCV genotype-4 infection consists of 48 weeks of PegIFN/RBV with a large proportion of patients do not achieve SVR with this treatment regimen.

All subjects will receive 12 weeks triple therapy of TMC435 150 mg once daily and PegIFN/RBV, followed by PegIFN/RBV alone. The duration of total treatment is response guided in treatment naïve and prior relapser subjects and patients are eligible to stop all treatment at week 24 if predefined response-guided criteria are met. Subjects with cirrhosis will receive 48 weeks of therapy, irrespective of on-treatment virologic response and treatment history. The primary endpoint in the study is SVR12.

TMC435 - Ongoing global phase III program in brief:

· TMC435-C208 or QUEST-1 in 375 treatment-naïve genotype-1 patients
· TMC435-C216 or QUEST-2 in 375 treatment-naïve genotype-1 patients
· TMC435-C3007 or PROMISE in 375 genotype-1 patients who have relapsed after prior interferon-based treatment
· Phase III program in Japan, includes 417 genotype-1 treatment naïve and treatment experienced patients

Charlotte Edenius, Executive VP Research and Development, of Medivir commented,
"We are extremely pleased to expand the phase III program with these two new trials as we continue development of TMC435 for broad patient populations. The 744 patient HPC3001 study is aimed at further confirming the positive findings of the ASPIRE phase IIb trial in genotype-1 non-responder patient populations and in the HPC3011 study, the genotype-4 activity of TMC435 is being investigated.”

Medivir updates investors on Hepatitis C programs...

Medivir offers an update on it's HCV development projects including the phase IIb trials for it's once daily. HCV protease inhibitor TMC435 and the early development programs for it's HCV nucleoside and a nucleotide inhibitors. For TMC435: results from the PILLAR trial looking at TMC435 + P/R in treatment naive genotype 1 subjects found 81-86% of patients achieved SVR24, compared to 65% in the placebo + P/R arm. A majority of patients (86%) in the TMC435 treatment arms had a shortened treatment duration of treatment (24 weeks), compared to a 48 weeks in the placebo + P/R arm. For the ASPIRE trial, looking at TMC435 + P/R in partial and null responders to previous treatment. The TMC435 subgroups achieved substantially higher viral cure rates (SVR24) compared to the control group (PegIFN and RBV alone): 85% vs. 37% in prior relapsers, 75% vs. 9% in prior partial responders and 51% vs. 19% in prior null responders. Other interesting notes include a change in primary endpoint from SVR24 to SVR12 in the TMC435 Phase III trials; a Phase III TMC435 + P/R vs Telaprevir + P/R in nonresponders yet to be started; an interferon-free, combination trial looking at TMC435 + Pharmasset's PSI-7977 with and without ribavirin in genotype 1 non-responders. We're likely to see more companies pair combinations of drugs as the 2nd and 3rd generation DAAs move forward in development and others are abandoned due to inferior efficacy and/or side effect issues.

Medivir: Key News from the Ongoing Capital Markets Day

HUDDINGE, Sweden, Nov 15, 2011 (BUSINESS WIRE) -- Regulatory News:

Medivir AB, a research-based speciality pharmaceutical company focused on infectious diseases, reports the following key news concerning their hepatitis C projects.

Medivir programmes in collaboration with Tibotec Pharmaceuticals Medivir and Tibotec Pharmaceuticals have two programmes for the development of antiviral therapies for future treatment of hepatitis C (HCV), these are based on the HCV protease and polymerase drug targets.

In the protease project, TMC435 is in global phase III development in both treatment naive and in patients that have relapsed after previous treatment with pegylated interferon (PegIFN) and ribavirin (RBV) in patients with chronic hepatitis C genotype 1.

The HCV polymerase collaboration program consists of two early development projects, a nucleoside and a nucleotide inhibitor.

TMC435 (NS3/4A protease inhibitor) presently in development in Hepatitis C genotype 1 infected patients.

Phase IIb studies Final SVR24 data from the phase IIb study PILLAR, in treatment-naive patients, was presented last week at the 62nd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco, CA, USA. Results from this final PILLAR analysis showed that TMC435 administered in combination with peginterferon a-2a and ribavirin (PR) resulted in significantly higher sustained virologic response (SVR) rates compared to placebo plus PR, with the majority of TMC435 patients able to shorten total treatment duration to 24 weeks based on response-guided therapy.

-- In the 150 mg TMC435 treatment groups, 81-86 percent of patients achieved SVR24, compared to 65 percent of patients treated in the placebo arm. In addition, 86 percent of patients in the TMC435 treatment arms had a shortened treatment duration of 24 weeks, compared to a 48 weeks treatment duration for patients who received placebo plus P/R.

-- The once daily dosed TMC435 was generally safe and well tolerated at all doses and treatment durations.

Medivir recently issued a press release on final results from phase IIb study ASPIRE This trial evaluated TMC435 once daily in addition to pegylated interferon (PegIFN) and ribavirin (RBV) in patients with chronic hepatitis C whose prior treatment with PegIFN and RBV was unsuccessful either because they relapsed, had a partial response or had a null response.

-- Data from the ASPIRE study showed that patients in each of these subgroups who were treated with TMC435-based combination therapy achieved superior rates of sustained virologic response (viral cure) compared to those retreated with pegylated-interferon and ribavirin alone.

-- All TMC435 subgroups achieved substantially higher viral cure rates (SVR24) compared to control group (PegIFN and RBV alone): 85% vs. 37% in prior relapsers, 75% vs. 9% in prior partial responders and 51% vs. 19% in prior null responders.

-- The once daily TMC435 was generally safe and well tolerated at all doses and treatment durations. Phase III studies

SVR12 - new endpoint

-- In the ongoing phase III studies in naive and patients that have relapsed following previous treatment, the primary endpoint has been changed from SVR24 to SVR12 following recent discussions with the FDA. These studies (QUEST 1 &2 and PROMISE) were all fully recruited in August.

Phase III study in non-responder patients to be initiated

-- Phase III study in prior partial and null responder HCV genotype 1 patients will start within six months. This study will evaluate efficacy, safety and tolerability for TMC435 vs telaprevir in combination with PegINFa-2a and Ribavirin in chronic Hepatitis C patients.

Phase II interferon free combination study with TMC435 and PSI-7977

-- This interferon free phase II combination study will commence shortly. It will evaluate TMC435 and PSI-7977 in combination with and without ribavirin for 12 and 24 weeks in genotype 1 patients who had a prior null response to Peg-IFN/RBV. The study design is now posted on www.clinicaltrials.gov .

HCV polymerase collaboration

TMC649128 TMC649128, the first NS5B nucleoside polymerase inhibitor under the collaboration, entered into clinical development in Q1-2011. It was safe and well tolerated at all doses tested for up to 14 days. However the antiviral activity failed to meet the target product profile and therefore the clinical development has now been discontinued.

Nucleotide program The focus of HCV polymerase collaboration is now on a liver targeted nucleotide polymerase inhibitor program. A clinical candidate has been selected and the project is now in preclinical development stage.

Capital Markets Day Presentation The presentation from this research & development update is available on our website under the heading Investor Relations / Latest Events.

Medivir: Completed Enrollment of Three Global Phase 3 Trials for TMC435 in Chronic Hepatitis C Genotype-1 Infected Patients

HUDDINGE, Sweden, Aug 31, 2011 (BUSINESS WIRE) -- Regulatory News:

MedivirAB (omx:MVIR) is an emerging research-based specialty pharmaceutical company focused on infectious diseases.

Medivir today announced that its investigational protease inhibitor TMC435, developed by Tibotec Pharmaceuticals, has successfully completed enrollment of three ongoing global phase 3 trials and further reports that all patients are now on TMC435 or active control treatment. The trials are QUEST 1 and QUEST 2, in treatment naive patients, and PROMISE in the treatment experienced relapser patient population. In all three trials, the duration of total treatment is response guided and patients in the TMC435 arms are eligible to stop all treatment at week 24 if predefined response-guided criteria are met.

Medivir recently announced that TMC435 had received "Fast Track" designation by the U.S. Food and Drug Administration ("FDA") for the treatment of chronic hepatitis C (CHC) genotype-1 infection. This is based on TMC435's potential to address unmet medical needs in the treatment of chronic HCV infection.

In parallel to these trials, phase 3 studies for TMC435 in Japan, in both treatment naive and treatment experienced hepatitis C genotype-1 infected patients, have also completed enrollment.

Global Phase 3 Program in brief:

- TMC435-C208 or QUEST-1 includes approximately 375 treatment-naive patients

- TMC435-C216 or QUEST-2 includes approximately 375 treatment-naive patients

- TMC435-C3007 or PROMISE includes approximately 375 who have relapsed after prior interferon-based treatment

Bertil Samuelsson, Chief Scientific Advisor at Medivir, comments - "We are extremely excited to have completed the enrollment and patient dosing in three large global phase 3 trials. It is a monumental milestone step for Medivir as a company and for TMC435 progress towards market registration. The completed enrollment of phase 3 studies for TMC435 in Japan represents another key project milestone achievement."

About TMC435

TMC435, an investigational CHC protease inhibitor currently in phase 3 clinical development, is a highly potent, selective and safe once-daily (q.d.) drug jointly developed by Tibotec Pharmaceuticals to treat chronic hepatitis C virus infections.

TMC435 is being developed both in combination with PegIFN/RBV and in combination with Direct-acting Antiviral (DAA) agents without peginterferon and with or without ribavirin (RBV).

In June 2011 the combination study of TMC435 with TMC647055, a non-nucleoside NS5B polymerase inhibitor being developed by Tibotec Pharmaceuticals, was initiated and in July 2011 Medivir confirmed the intention to start a proof-of-concept oral, interferon-free phase 2 trial, investigating the combination of TMC435 and Pharmasset's PSI-7977, a once daily nucleotide NS5B polymerase inhibitor. Phase 3 programs for TMC435 are also ongoing in Japan.

In parallel with the recent start of the global phase 3-studies, TMC435 is currently in a follow up phase in three phase 2b clinical trials (TMC435-C205, TMC435-C206 and TMC435-C215) in G1 treatment-naive and in G1 patients that failed previous IFN-based treatment. More safety and efficacy data from the phase 2b trials will be presented at scientific meetings later in 2011.

Medivir/Tibotec's HCV protease inhibitor TMC435 receives FDA 'Fast-Track' status...

Medivir: TMC435 has Received Fast Track Designation from the FDA and TMC435 will be studied in combination with Pharmasset's PSI-7977 for HCV genotype-1

HUDDINGE, Sweden, Jul 06, 2011 (BUSINESS WIRE) -- Regulatory News:

Medivir AB (sto:MVIRB)(omx:MVIR), is an emerging research-based specialty pharmaceutical company focused on infectious diseases.

Medivir today announced that its investigational protease inhibitor TMC435 has received "Fast Track" designation by the U.S. Food and Drug Administration ("FDA") for the treatment of chronic hepatitis C (CHC) genotype-1 infection. This is based on TMC435's potential to address unmet medical needs in the treatment of CHC infection compared to currently approved therapies.

TMC435 may offer:

-- High sustained virological response (SVR) rates in genotype-1 HCV-infected patients, including hard-to-treat subgroups

-- Short treatment duration

-- Favorable overall safety and tolerability profile

-- A convenient once-daily (q.d.) dosing regimen

Furthermore, Medivir also confirms the intention to start a proof-of-concept oral, interferon-free phase 2 trial, investigating the combination of TMC435, a once daily NS3/4A protease inhibitor (PI) for the treatment of genotype-1 chronic hepatitis C virus (HCV) infection and Pharmasset's PSI-7977, a once daily nucleotide NS5B polymerase inhibitor. The phase 2 study, which is being managed by Tibotec Pharmaceuticals, will investigate the efficacy and safety of 12 weeks or 24 weeks of TMC435 150 mg q.d. in combination with PSI-7977 400 mg q.d. with or without ribavirin in prior null responders to peginterferon/ribavirin therapy. The primary endpoint of the trial will be sustained virological response at 12 weeks (SVR12).

Bertil Samuelsson, CSO, of Medivir commented, "We are delighted to have received the Fast Track designation for TMC435 from the FDA. This shows that TMC435 with its high safety profile, efficacy, short treatment duration and convenience of once daily dosing is believed to have the potential to provide benefit over current treatments. We believe TMC435 has the potential to become a cornerstone of future direct-acting antiviral combinations for HCV therapy. We are thus very pleased over the clinical collaboration agreement Pharmasset announced today with Tibotec, and the coming start-up of a TMC435 combination trial with Pharmasset's once daily NS5B nucleotide inhibitor PSI-7977. This is one of several ongoing TMC435 combination trials and we expect the momentum to continue with regards to the development of TMC435"

About Fast Track

Fast Track is a process designed to facilitate the development, and expedite the review of drugs to treat serious diseases and to fill an unmet medical need. The purpose is to get important new drugs to the patient earlier. Fast Track addresses a broad range of serious diseases. "Filling an unmet medical need" is defined as providing a therapy where none exists or providing a therapy that may potentially be superior to existing therapy. If there are existing therapies, a fast track drug must show some advantage over available treatment, such as:

-- Showing superior effectiveness

-- Avoiding serious side effects of an available treatment

-- Improving the diagnosis of a serious disease where early diagnosis results in an improved outcome

-- Decreasing a clinically significant toxicity of an accepted treatment

A drug that receives Fast Track designation is eligible for some or all of the following:

-- More frequent meetings with the FDA to discuss the drug's development plan and ensure collection of appropriate data needed to support drug approval

-- More frequent written correspondence from the FDA about such things as the design of the proposed clinical trials

-- Eligibility for Accelerated Approval, i.e., approval on an effect on a surrogate or substitute endpoint reasonably likely to predict clinical benefit

-- Rolling Review, which means that a drug company can submit completed sections of its New Drug Application (NDA) for review by FDA, rather than waiting until every section of the application is completed before the entire application can be reviewed. NDA review usually does not begin until the drug company has submitted the entire application to the FDA

-- Dispute resolution if the drug company is not satisfied with an FDA decision not to grant Fast Track status.

In addition, most drugs that are eligible for Fast Track designation are likely to be considered appropriate to receive a Priority Review.

Once a drug receives Fast Track designation, early and frequent communication between the FDA and a drug company is encouraged throughout the entire drug development and review process. The frequency of communication assures that questions and issues are resolved quickly, often leading to earlier drug approval and access by patients.

About TMC435

TMC435, an investigational CHC protease inhibitor currently in phase 3 clinical development, is a highly potent, selective and safe once-daily (q.d.) drug jointly developed by Tibotec Pharmaceuticals to treat chronic hepatitis C virus infections.

TMC435 is being developed in combination with PegIFN/RBV and in combination with Direct-acting Antiviral (DAA) agents without peginterferon and with or without ribavirin (RBV). In June 2011 the combination study of TMC435 with TMC647055, a non-nucleoside NS5B polymerase inhibitor being developed by Tibotec Pharmaceuticals, was initiated.

Three global clinical phase 3 response guided studies were initiated in early 2011 by Tibotec:

-- TMC435-C208 or QUEST-1 includes approximately 375 treatment-naive patients

-- TMC435-C216 or QUEST-2 includes approximately 375 treatment-naive patients

-- TMC435-C3007 or PROMISE includes approximately 375 who have relapsed after prior interferon-based treatment

Phase 3 programs for TMC435 are also ongoing in Japan.

In parallel with the recent start of the global phase 3-studies, TMC435 is currently in a follow up phase in three phase 2b clinical trials (TMC435-C205, TMC435-C206 and TMC435-C215) in G1 treatment-naive and in G1 patients that failed previous IFN-based treatment. More safety and efficacy data from the phase 2b trials will be presented at scientific meetings later in 2011.

Medivir Announces Positive 48-week Interim Data from TMC435 Hepatitis C Phase 2b ASPIRE Study in Treatment-Experienced Genotype-1 Patients...

I need to add 'SVR4' to my list of HCV Direct Acting Antiviral terminology... 'SVR4' is SVR 4 weeks post end of treatment date. Glad to get that squared away. This press release covers the majority of results of the phase IIb trial (ASPIRE) with the HCV protease inhibitor TMC435 looking at those who were previous non-responders to previous Peg-inf + P/R therapy - Relapsers, Partial Responders and Null-Responders to be specific. SVR4 in the TMC435 150mg + P/R was achieved in 88%, 77% and 57% oof those respective populations vs 50%, 11% and 23% in the placebo + P/R ar, again, respectively. No relevant differences between the 12, 24 and 48 week arms. Serious AEs were reported in 6.1% subjects in the placebo and vs 8.3% of the subjects treated with TMC435 with no substantial differences seen between the TMC435 dose groups. AEs leading to treatment discontinuation were reported in 4.5% of the placebo subjects and in 8.8% of the TMC435 treated subjects. The relative lack of AE's compared to the first generation of HCV PIs and the once a day dosing make TMC435 one to keep our eyes on.

HUDDINGE, Sweden, May 20, 2011 /PRNewswire/ --

- All TMC435 Patient Subgroups Achieved Substantially Higher SVR4 Rates (Undetectable Virus 4 Weeks After End of Treatment) Compared to pegylated-interferon and ribavirin Alone

- TMC435 was Safe and Well Tolerated at All Doses and Treatment Durations

Medivir AB (OMX: MVIR), the emerging research-based specialty
pharmaceutical company focused on infectious diseases, today announced results from the ASPIRE phase 2b study that evaluates the addition of once daily TMC435 to pegylated interferon and ribavirin in patients with genotype 1 chronic hepatitis C whose prior treatment with pegylated-interferon (PegIFN) and ribavirin (RBV) was unsuccessful either because they relapsed, had a partial response or had a null response.

Bertil Samuelsson, CSO of Medivir, commented, "We are delighted with the encouraging efficacy and safety results shown by TMC435-based triple therapy over pegylated-interferon and ribavirin, in this 48-Week interim analysis of the ASPIRE study in treatment experienced genotype-1 hepatitis C patients. This patient group is known to be the most difficult one to treat, where in particular prior null and partial responder groups respond very poorly upon retreatment with PegIFN/RBV alone. With several global phase 3 clinical trials ongoing in hepatitis C patients we are expecting the momentum to continue with regards to the development of TMC435."

ASPIRE (C206) - Design and Week-48 Interim Analysis
TMC435, a potent, once-daily, oral hepatitis C virus protease inhibitor is being developed by Tibotec jointly with Medivir. The randomized, placebo-controlled, double-blind ASPIRE study evaluates the effect of TMC435 in combination with pegylated-interferon and ribavirin in 462 patients infected with genotype-1 hepatitis C virus who have failed prior treatment with PegIFN/RBV. The study includes patients that have relapsed, achieved partial response, or achieved no response (null responders) to SoC treatment and where 62 percent (287/462) of patients overall had advanced liver disease, periportal or septal fibrosis or cirrhosis (scarring of the liver) upon study entry (Metavir score F2-F4).

Patients were equally randomized to 1 of 7 different treatment arms: 6 TMC435 treatment arms and one placebo arm. TMC435 was administered once daily at a dose of either 100 mg or 150 mg given for either 12, 24, or 48 weeks in combination with PegIFN/RBV. PegIFN/RBV treatment was continued in all patients until the study completion at week 48. This interim analysis was performed when all patients had completed 48 weeks of treatment or discontinued earlier. The analysis was done based on the intent-to-treat, ITT, population which included all randomized subjects who took at least one dose of the study medication. SVR4, Sustained Virologic Response 4 weeks after planned end of treatment data, was available for 94% and 84% of TMC435 and placebo patients respectively.

ASPIRE Results - Efficacy
In this Week 48 interim analysis, all subgroups of treatment-experienced patients who failed previous peginterferon and ribavirin treatment, achieved substantially higher virologic response rates following treatment with TMC435-containing regimen at all doses and durations, compared with pegylated-interferon and ribavirin.

There was no relevant difference in virological response between the TMC435 150 mg dose groups who received TMC435-based triple therapy of 12 weeks, 24 weeks or 48 weeks. At end of treatment (EoT) 92%, 83% and 71% of relapser patients, partial responder patients and null responder patients taking TMC435 150 mg once daily and placebo, respectively, achieved undetectable HCV RNA levels compared to 70%, 17% and 25% in the placebo PegIFN/RBV groups respectively. At week 4 after cessation of treatment (SVR4) 88%, 77% and 57% of prior relapser patients, partial responder patients and null responder patients taking TMC435 150 mg once daily and placebo, respectively, achieved undetectable HCV RNA levels, compared to 50%, 11% and 23% in the placebo groups, respectively.

Prior Null Responders: less than 2 log reduction in HCV RNA at W12
Results - Safety and Tolerability

TMC435 was generally safe and well tolerated and overall incidence of adverse events (AEs) was similar across treatment groups. Most of the AEs were grade 1 or 2 in severity. Serious AEs (SAEs) were reported in 6.1% subjects in the placebo and in 8.3% of the subjects treated with TMC435 with no substantial differences seen between the TMC435 dose groups. AEs leading to treatment discontinuation were reported in 4.5% of the placebo subjects and in 8.8% of the TMC435 treated subjects. Patients in the TMC435 ASPIRE treatment groups had overall longer treatment duration than patients in the placebo group due to a higher frequency of early discontinuation in the placebo group caused by treatment failures (i.e. reaching viral stopping rules). The most common AEs during the treatment period were headache, fatigue, pruritus and influenza-like illness.

Incidence was similar across treatment groups and the level of AEs and frequency were consistent with prior phase 2b PILLAR study of TMC435.
In the safety analyses, special attention was given to the following AEs of interest: hepatobiliary AEs, pruritus, rash, anemia and cardiac events. Most AEs of interest were grade 1 or 2 in severity and infrequently led to treatment discontinuation. For each category of AEs of interest the incidence was similar with TMC435 and PegIFN/RBV.

Mild and reversible increases in bilirubin (total, direct and indirect) were observed in TMC435 dose groups with no differences between 100 mg and 150 mg. There were no meaningful differences between treatment groups for any of the other laboratory parameters. There were no clinically significant findings on vital signs, nor were there any relevant changes in electrocardiogram (ECG) parameters, including QTc. Mean alanine aminotransferase (ALT) levels decreased in all treatment groups.

Medivir to buy BioPhausia to "create a platform" for the launch of TMC435....

Medivir to buy BioPhausia for 62 million euros
World News | April 12, 2011

Medivir is to acquire fellow Swedish firm BioPhausia in a deal that will "create a platform" for the launch of its promising hepatitis C treatment.

Under the terms of the deal, Medivir is offering a mixture of cash and new shares, thus valuing BioPhausia at around 565 million Swedish kroner (62 million euros) or 1.65 crowns per share. The offer represents a 44% premium over the average price of BioPhausia shares over the last 30 days and the latter's board has unanimously recommended the offer.

The Huddinge-headquartered group says that BioPhausia will provide it with "complementary competencies in regulatory affairs, logistics, distribution, marketing, sales and quality assurance", plus a local presence in Sweden, Denmark and Finland. It also brings quite healthy revenues; turnover in 2010 came in at 506 million kroner, compared to Medivir's 62 million kroner.

Seeking sustainable profits

Ron Long, Medivir's chief executive, said the acquisition brings the firm closer to "achieving its goal of becoming a sustainably profitable, research-based specialty pharmaceutical company". He added that the BioPhausia team will "significantly advance our commercial capabilities as we prepare to realize full value from TMC435".

The latter is a once-daily, protease inhibitor for hepatitis C, which is partnered with Johnson & Johnson affiliate Tibotec and has recently reported positive interim data in three Phase IIb studies. It has moved to Phase III and Medivir has retained full commercial rights to TMC435 in the Nordic region.

Medivr/Tibotec QD HCV PI TMC435 Interim 24 week data from Phase 2b ASPIRE trial presented at EASL...

This is by far the cockiest press release I've read thus far that's associated with EASL, and I've had an eyeful. But the Medivir/Tibotec partnership has good reason to be at least somewhat arrogant. If they can keep these numbers looking as good 6 months post-treatment, then TMC435 will be the next gen DAA poised to usurp what looks to be Telaprevir’s throne. TMC435 looks to have extraordinary efficacy and tolerability in combination with PEG and Ribavirin at 24 weeks, boasting as much as 93.3% week 24 HCV RNA < 25 IU/mL in prior NULL responders in the 48 weeks TMC435 + Peg + RBV for 48 weeks arm (yes, NULL responders!) . Take a look at the tables here: http://www.prnewswire.com/news-releases/medivir-week-24-interim-results-from-tmc435-hepatitis-c-phase-2b-aspire-study-presented-at-easl-119040924.html

HUDDINGE, Sweden, April 1, 2011 /PRNewswire-FirstCall/ --

- Results Show Potent Antiviral Efficacy of Once Daily 150 mg TMC435 in Hepatitis C Patients Who Have Failed Earlier Treatment, Especially in Prior Null Responders, and Excellent Safety and Tolerability

Medivir AB (OMX: MVIR), the emerging research-based specialty pharmaceutical company focused on infectious diseases, announces that their partner, Tibotec has presented the results of a planned Week 24 interim analysis of the phase 2b ASPIRE study for TMC435 in treatment experienced hepatitis C patients in a late-breaker session at the 46th Annual meeting of the European Association for the Study of the Liver (EASL), Berlin, Germany.

Treatment experienced patients are known to be the most difficult to treat hepatitis C patient group.

TMC435 is a potent, once-daily, oral hepatitis C virus protease inhibitor which recently entered clinical phase 3 studies. The study enrolled patients chronically infected with genotype-1 hepatitis C virus (HCV) that had previously failed treatment with standard of care therapy (peginterferon and ribavarin). TMC435 is being jointly developed by Medivir and its partner Tibotec.

In this Week 24 interim analysis, treatment-experienced patients who failed peginterferon and ribavarin treatment achieved significantly greater virologic response rates following treatment with TMC435-containing regimen at all doses, compared with placebo. Results demonstrated that the TMC435 150 mg dose group showed the highest response, particularly in prior null responders. In this 150 mg dose group, HCV RNA levels were undetectable at week 24 for between 82% and 91% of the patients. Results also showed that there was no statistically relevant difference in safety and tolerability between the TMC435 and placebo treated groups.

Ron Long, CEO of Medivir, commented: "We are delighted that these strong results are to be presented at such a prestigious scientific conference as EASL. TMC435 continues to demonstrate why Medivir are so confident that hepatitis C treatment can be significantly changed by a more convenient, once daily protease inhibitor especially for treatment experienced patients. These data and the recent start of phase 3 clinical studies for TMC435, represent an exciting stage in Medivir's development as a significant player in the infectious disease market."

The ASPIRE study evaluates the effect of TMC435 in combination with standard of care (SoC) in 462 patients infected with the difficult to treat genotype-1 hepatitis C virus who had undergone and failed prior treatment with (SoC). The study includes patients that have relapsed, achieved partial response, or achieved no response (null responders) to treatment with standard of care. TMC435 was administered once daily at a dose of either 100 mg or 150mg given for either 12, 24, or 48 weeks in combination with standard of care. Standard of care treatment was continued until the study completion at week 48.

As well as the late-breaker ASPIRE data presented, a further three presentations will be made at EASL on TMC435. These include:

Oral presentation: Impact of IL28b genotype and pretreatment serum IP-10 in treatment-naive genotype-1 HCV patients treated with TMC435 in combination with peginterferona-2a and ribavirin in PILLAR study, J. Aerssens, which found that during 24 weeks of treatment, IL28B genotype and serum IP-10 were predictive of response in patients receiving standard of care (peginterferon and ribavirin) but had limited predictive value in patients treated with both TMC435 and peginterferon and ribavirin, therefore suggesting that TMC435, a potent, once daily oral protease inhibitor, may overcome the negative consequences of unfavourable host genotype encountered with pegIFN/RBV.

Poster presentation No.472: Pharmacokinetics of TMC435 in subjects with moderate hepatic impairment, V. Sekar, which found that no TMC435 dose adjustment was necessary for patients with moderate liver impairment.

Poster presentation No.1221: Treatment outcome and resistance analysis in HCV genotype 1 patients previously exposed to TMC435 monotherapy and re-treated with TMC435 in combination with pegifna-2a/ribavirin, O. Lenz, which found that viral variants in patients who had received TMC435 as a monotherapy were no longer detected over time and successful treatment after prior exposure to TMC435 with emergence of resistance variants was possible in 3/5 patients who had failed interferon-based therapy.

Medivir announces SVR24 in TMC435 in Phase 2b Treatment-naive patient population....

A might bit too early to fully put on my 'bullish' hat, still have to see what the final SVR will look like in all the arms (especially the placebo SOC arm), but TMC435 plus peg/riba looks awfully strong. Add in once daily dosing and equal DC's between placebo arm and TMC435 arms... the early data in this trial looks promising. We'll all be anxiously awaiting results for Medivir's ASPIRE trial in treatment-experienced patients coming in Q2 of this year.

HUDDINGE, Sweden, February 22, 2011 /PRNewswire-FirstCall/ -- Medivir AB (OMX: MVIR), the emerging research-based specialty pharmaceutical company focused on infectious diseases, announces today further positive results from the phase 2b PILLAR (C205) study of TMC435 in treatment-naive patients with hepatitis C virus (HCV) genotype-1.

- TMC435 was safe and well tolerated with no clinically
relevant differences in adverse events between treatment groups and
standard of care (SoC).
- In the TMC435 treatment groups 83% of patients were able to stop
all therapy at week 24
- Potent and consistent antiviral efficacy was demonstrated with
SVR24 rates of up to 84%

"We are very pleased by both the efficacy and safety shown by TMC435 in this 48-Week interim analysis. With the additional features of once daily dosing, TMC435 also has a more convenient and competitive dosing regimen" stated Bertil Samuelsson, CSO of Medivir. "The recently published start of three global phase 3 clinical trials is an important milestone in the continued development of TMC435. We are now looking forward to the 48-week interim data from the phase 2b trial C206 (ASPIRE) in treatment-experienced patients during Q2 2011."

The 48-week interim results from the 5-arm phase 2b response guided PILLAR study in 386 treatment-naive patients showed further consistent high antiviral activity, and the good safety and tolerability previously demonstrated was confirmed. The 24-week (EOT) interim results were presented at the AASLD conference in Boston, MA, in November 2010.

Study design
In the PILLAR study, 75mg or 150mg TMC435 was given for either 12 or 24 weeks in combination with 24 weeks of ribavirin and pegIFNalpha-2A, the current standard of care (SoC). Patients in the TMC435 arms stopped all treatment at week 24 if certain predefined response-guided criteria were met. In the TMC435 treatment groups 83% of patients were able to stop all therapy at week 24. Patients who did not meet the above response-guided criteria continued with SoC until week 48 as did the placebo group.

Evaluation criteria
A protocol-defined interim analysis was performed when all patients completed their Week 48 visit or discontinued treatment earlier. Final SVR4 and SVR24 data were available for 98% (303/309; n/N) and 93% (288/309; n/N) of TMC435 treated patients, respectively. SVR24 is determined 24 weeks after the planned end of treatment (EoT) and was therefore not yet available for the patients in the placebo group and for some of those in the TMC435 group who received 48 weeks of treatment. SVR4, which is determined 4 weeks after the planned EoT, was available for 77% (59/77; n/M) of the patients in the placebo group.

Results - Efficacy
Potent and sustained antiviral efficacy was demonstrated in the SVR4 and SVR24 rates with no major differences between TMC435 doses or length of triple therapy. At week 4 after cessation of treatment 87.2%, 86.5%, 84.9% and 88.5% of patients taking TMC435 and Peg-IFN/RBV (SoC) achieved undetectable HCV RNA levels. At week 24 after cessation of treatment 83.6%, 76.1%, 83.1% and 84.4% of patients taking TMC435 and Peg-IFN/RBV (SoC) achieved undetectable HCV RNA levels, i.e. SVR24. At week 4 after cessation of treatment 71.2% in the placebo SoC group had achieved undetectable HCV RNA levels.

The results are derived from an intent-to-treat (ITT) analysis of the patient population who took at least one dose of the study medication and who reached the criteria for stopping all treatment at 24 weeks (83%).

Results - Safety and Tolerability
TMC435 was generally safe and well tolerated and overall incidence of adverse events (AEs) was similar across treatment groups. AEs leading to discontinuation of TMC435 or placebo treatment were reported in 7.8% of the placebo subjects and in 7.1% of the TMC435 treated subjects. In the safety analyses, special attention was given to the following AEs of interest: hepatobiliary AEs, pruritus, rash, anemia, and cardiac events. For each category of AEs of interest; the incidence was similar between TMC435 and placebo.

In laboratory parameters, there were no clinically relevant differences between any TMC435 groups and placebo except for mild on treatment reversible bilirubin elevations (total, direct and indirect) in the 150 mg TMC435 arm, which were normalized after TMC435 dosing was completed. There were no meaningful differences between treatment groups for any of the other laboratory parameters. Significant and rapid decreases in transaminases (ALT and AST) were observed in all TMC435 treatment groups.

Medivir Announces Start of Phase 1a Trial of the Hepatitis C Polymerase Inhibitor TMC649128

Medivir Announces Start of Phase 1a Trial of the Hepatitis C Polymerase Inhibitor TMC649128

10-Feb-11 Huddinge, Sweden - Medivir AB (OMX: MVIR), the emerging research-based specialty pharmaceutical company focused on infectious diseases,today announces the start of a phase 1a clinical trial with TMC649128 intended for the treatment of chronic hepatitis C virus infection.

TMC649128 is a nucleoside NS5B polymerase inhibitor that has already demonstrated an attractive pre-clinical profile. It is anticipated that this profile would see TMC649128 be used in combination with HCV directly acting antiviral agents, given their high genetic barrier to resistance and antiviral activity across multiple HCV genotypes.

In pre-clinical studies, TMC649128 displayed in vitro activity across multiple HCV genotypes and a high genetic barrier to resistance.

The phase 1a trial is a double-blind, randomized, placebo-controlled single-ascending dose trial to assess the safety, tolerability and pharmacokinetics in healthy volunteers and will be conducted in Belgium. TMC649128 is being developed in collaboration with Tibotec Pharmaceuticals.

Milestone payment

Medivir entered a Research and Development agreement in the field of hepatitis C virus polymerase with Ortho Biotech Products LP, an affiliate of Tibotec in May 2008. The development of TMC649128 falls under this agreement and by entering clinical development, a milestone payment of Euro 7 million has been triggered for payment to Medivir.

“We are extremely excited to see TMC649128, our first HCV nucleoside inhibitor, move into clinical development”, stated Bertil Samuelsson, CSO of Medivir. "The start of this phase 1a trial underlines Medivir’s commitment to the development of novel and innovative hepatitis C treatments. We view nucleoside inhibitors as cornerstone components of future HCV treatment paradigms in combination with directly acting antiviral agents and a TMC649128 component could set them apart from other HCV drug classes.”

Medivir raises $41 million from institutional investors for TMC435 and beyond....

Medivir Creates Runway for TMC435 with $41M Placement

By Nuala Moran
BioWorld International Correspondent

LONDON – Medivir AB raised €30.8 million (US$41 million) in a private placement that brings in international institutional investors in the lead up to the start of Phase III trials of the lead product, TMC435, a protease inhibitor for treating hepatitis C (HCV) infections.

"The strategy is to broaden the shareholder base outside Scandinavia," said Rein Piir, CFO. All the new shareholders are, "high-quality, top-rank, U.S., Swiss, Dutch and UK investors," he told a teleconference held to discuss the placement.

In total, Huddinge, Denmark-based Medivir issued 2.25 million new shares at SEK125 ($18.23) each to 30 international institutional investors, plus some institutions in Sweden that were not already shareholders.

That represented a 7.9 percent dilution for existing investors. More than two-thirds of the new shares were taken up by international investors. Medivir is quoted on the Nasdaq OMX Exchange in Stockholm.

"This will enable Medivir to strengthen its R&D and take a higher amount of value going forward, by doing joint ventures rather than licensing, and [allowing us to] take products further," Piir said.

Medivir announced its intention of doing the placing in March when it sought approval from shareholders, but its ability to do so rests on positive Phase IIb data for TMC 435. The product is partnered by Johnson & Johnson subsidiary Tibotec Pharmaceuticals Ltd., with Medivir retaining rights in Nordic markets.

Last month, Medivir announced positive interim data from Aspire, a Phase IIb study of TMC 435 as a once-daily therapy in 462 HCV patients who had been treated previously with pegylated interferon (peg-INF).

TMC 435, added to standard of care, increased the number of patients whose HCV levels were undetectable at 24 weeks.

Across four treatment groups, between 79 percent and 86 percent of patients were able to stop taking any therapy at 24 weeks. Patients in the study were infected with genotype 1 HCV, which is hard to treat.

The product also had positive results in a 386-subject Phase IIb study in treatment-naïve patients, which reported in July. Here, 83 percent of those treated with TMC 435 were able to stop all therapy at 24 weeks.

Those results were presented by Tibotec at the Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in Boston, in October.

"We witnessed enthusiasm for TMC435 at the AASLD clinical meeting, which together with positive Phase IIb Aspire results, boosts our confidence and price target, by 6 percent," noted Peter Welford, equity analyst at Jeffries in London

The shares closed at SEK120 on Dec. 3, the day the completion of the placing was announced. Welford added that Medivir is, "The European biotech best placed to benefit from broad enthusiasm for the wave of new blockbuster hepatitis C therapies reaching the market."

Building on the success of TMC 435, the company has other HCV products coming through its pipeline. "Investors are supporting Medivir in efforts to become a leading player in HCV," Piir said.

The company also intends to apply its technology to new therapeutic areas. "We are in discussion on [doing] this in a joint venture structure," Piir added.

Medivir/Tibotec's TMC435 looking good in partial and non-responders....

This should get interesting in terms of revenue streams - Medivir is developing TMC435 with Tibotec who will market the drug in the US. Tibotec has marketing rights for Telaprevir everywhere except North America and the Far East. Telaprevir will be out first, depending on how things go with the European regulatory folks. How Tibotec prioritizes TMC435 development with Telaprevir marketing abroad is unclear. Looks like a darn good drug though. Good numbers and QD dosing.

By Frances Schwartzkopff - Nov 18, 2010

Medivir AB, the drugmaker competing to develop a new hepatitis C medicine, rose the most in four months in Stockholm trading after its drug reduced the virus to undetectable levels in patients who failed earlier treatment.

After 24 weeks, 86 percent of patients who had only partially responded to earlier treatment had undetectable virus levels after taking TMC435 alongside standard care, the Huddinge, Sweden-based company said in a study published today. That compared with undetectable levels in 19 percent of patients receiving a placebo. Shares rose as much as 9.2 percent.

Medivir is developing TMC435 with Tibotec Pharmaceuticals. The drugmaker, a unit of New Brunswick, New Jersey-based Johnson & Johnson, also is working simultaneously with Vertex Pharmaceuticals Inc. on a new hepatitis C drug.

Vertex, based in Cambridge, Massachusetts, plans to seek U.S. approval for its medicine, Telaprevir, by the end of the year.

Medivir, which still needs to conduct the last trial needed to seek regulatory approval, said 78 percent of patients who didn’t respond at all to initial treatment had undetectable virus levels after taking TMC435, almost twice as many as those who received a placebo.

The medication also led to undetectable virus levels in 94 percent of patients who had relapsed after receiving earlier care. That compared with 83 percent of patients taking a placebo. 462 patients participated in the 48-week study, with results taken half way through.

Medivir rose 8.5 kronor, or 6.8 percent, to 133.5 kronor at 12:54 p.m. local time. The advance gave the drugmaker a market value of 3.5 billion kronor ($511 million), its highest since December 2000.
