BMS formally suspends development of BMS-094...

Posted 8/23/2012 on Fox Business.com.  BMS formally suspends development of nucleoside inhibitor BMS-094/INX-189 due to possible heart and kidney toxicity. One subject died, nine were hospitalized and two remain so at the time of press. The cause of the events has not yet been identified. Ramifications have already been felt through the HCV drug development space, with Idenix's IDX184 clinical trial, a nucleoside inhibitor similar in structure to BMS-094, put on partial clinical hold by the FDA. The FDA hinted in it's letter to Idenix that there were possibilities of similar actions to other nucs in development as well.

Bristol-Myers Discontinues Development of Hepatitis C Drug
Published August 23, 2012

Dow Jones Newswires

Bristol-Myers Squibb Co. (BMY) said Thursday it has discontinued the development of a drug intended to treat the liver disease hepatitis C in the interest of patient safety, after a patient died and others were hospitalized.

Bristol-Myers earlier this month voluntarily suspended a Phase 2 study of BMS-986094, which was formerly known as INX-189, a nucleotide polymerase inhibitor, or "nuke." The initial case of heart failure, which was the basis for halting the study, subsequently resulted in death, the company said Thursday.

Bristol-Myers said it is working with the U.S. Food and Drug Administration and clinical study investigators to conduct ongoing and close follow-ups of all the study's patients. To date, nine patients have been hospitalized, including the initial patient, and two remain hospitalized.

The company said the cause of these unexpected events, which involve heart and kidney toxicity, hasn't been definitively established.

Bristol-Myers decision to halt the study earlier this month raised questions about the experimental drug's potential and the $2.5 billion price tag Bristol paid earlier this year to buy the company that developed it. The suspension was considered a significant setback for the drug maker--already grappling with weak sales of its Plavix anticlotting drug that lost patent protection in May--in the race to develop new hepatitis C treatments.

Bristol-Myers as well as other companies such as Gilead Sciences Inc. (GILD) and Abbott Laboratories (ABT) has been looking to bring the first all-oral hepatitis C regimen to market, hoping to tap what is expected to be a multibillion-dollar market for such a therapy.

To strengthen its hepatitis C position, Bristol-Myers in February shelled out $2.5 billion to buy Inhibitex Inc. at a whopping 163% premium. Bristol was lured primarily by Inhibitex's nuke for hepatitis C, though it did acquire other potential treatments for infectious disease in the deal.

Treatments for hepatitis C are considered lucrative because the disease is prevalent in large sections of the global population. The virus, which can be transmitted sexually or through use of shared needles and at tattoo parlors, affects some 170 million people world-wide.

Separately, Synergy Pharmaceuticals Inc. (SGYP) said it has agreed to acquire the assets related to shingles treatment FV-100 from Bristol-Myers. FV-100 was developed by Inhibitex.

Shares were up by 10 cents to $32.25 after hours. The stock has fallen 8.8% since the start of the year.

BMS halts development of Phase 1 anti-HCV nuc, BMS-986094...

Posted 8/2/12 on MedPage Today.com. BMS halts development of its investigational nuc BMS-986094 for treatment of chronic HCV after one of the patients the 200mg arm of the  phase 1 trial suffered heart failure. It is unknown at time of publishing whether the drug was directly linked to the drug and all patients involved with the trial are undergoing full assessment.  This effectively makes GS-7977, Gilead's nucleotide analog one of the only nucs currently in advanced development unscathed by toxicity and certainly adds to it's luster, at least in the short term. 

Safety Issue Halts Study of BMS HCV Drug

Bristol-Myers Squibb has suspended treatment "to protect patient safety" in a phase IIb trial of an investigational oral drug for hepatitis C.

A spokeswoman for the company said the decision was made after one of the patients getting 200 mg of the compound, dubbed BMS-986094, suffered heart failure.

Bristol-Myers Squibb is not giving further details on the patient's condition, according to Cristi Barnett, the company's associate director of public affairs.

In an email to MedPage Today, Barnett said it's still not clear what caused the heart failure or whether it's related to the study drug. To try to clarify the issue, BMS is doing "an immediate assessment of all patients receiving 094 at any dose," Barnett said.

"This assessment includes full physical exams and histories, and cardio ECHO imaging and ECGs for all patients," Barnett said. "Any clinically significant cardiac ECHO abnormality will then be reviewed by a consulting cardiologist as soon as possible."

The drug is a nucleotide NS5B polymerase inhibitor and was acquired by the company when it paid $2.5 billion in January to purchase Inhibitex, the original developer. It was first known as INX-08189.

It's one of several under development -- both Gilead Sciences of Foster City, Calif., and Vertex Pharmaceuticals of Cambridge, Mass., have competitors in the field.

The range of potential treatments for the virus, blamed for about 15,000 deaths annually in the U.S., has been expanding dramatically with the recent development of so-called direct-acting agents.

Two HCV protease inhibitors -- telaprevir (Incivek) and boceprevir (Victrelis) -- are already on the market, but they are indicated for use with pegylated interferon-alfa and ribavirin, which aim at stimulating the immune system rather than targeting the virus directly.

The goal has been to develop all-oral combinations of direct-acting agents that would eliminate the need to use interferon and ribavirin.

BMS-986094 was being tested in a two-part dose-ranging study, dubbed AI472-003, among patients with HCV genotypes 2 or 3 who had not been previously treated. Genotypes 2 and 3 are regarded as being easier to cure than genotype 1.

The first part of the 12-week study was double-blinded and included 90 patients in four treatment arms. In the comparator arm, patients were treated with pegylated interferon-alfa and ribavirin, plus an oral placebo.

In the remaining arms, patients got interferon and ribavirin plus 25, 50, or 100 mg of BMS-986094.

The second part of the study, planned to include 120 patients, was open label for 12 weeks and had five arms.

In two arms, patients took either 100 or 200 mg of BMS-986094, combined with ribavirin. In two others, they took the same doses of the drug, this time combined with daclatasvir, the company's investigational NS5A replication complex inhibitor.

Finally, in the fifth arm, they took 50 mg of BMS-986094 and both daclatasvir and ribavirin.

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.
