Aethlon Medical Reports Undetectable Hepatitis C Virus (HCV) in Genotype 1, Genotype 3, and Genotype 5 Patients Treated with Hemopurifier® Therapy


Posted on 5/8/12 on MarketWatch.com. Good news for San Diego's microtech, Aethlon Medical in the form of a trial results looking at it's Hemopurifier filtration device in combination with pegylated interferon and ribavirin in patients infected with HCV genotype 1, 3 and 5. The hemopurifier is a first-in-class device that selectively targets HCV by filtering the circulatory system for virus thus enhancing the work of traditional oral and injectable anti-HCV drugs. If proven effective, Hemopurifier could be a great asset to HCV providers by possibly being able to lower the dose and duration of HCV therapy - and, given the cost of the 1st generation of oral anti-HCV Direct Acting Antivirals - could provide a cost benefit as well. The Hemopurifier seems to be very effective in genotype 1 patients which is encouraging - if just pegylated interferon and ribavirin are used there is not only a possible cost benefit, but also a possible greatly reduced propensity for the patient to develop drug-resistant variants. Further studies are needed of course, but this initial bit of news is encouraging. 


Aethlon Medical Reports Undetectable Hepatitis C Virus (HCV) in Genotype 1, Genotype 3, and Genotype 5 Patients Treated with Hemopurifier® Therapy

SAN DIEGO, May 8, 2012 /PRNewswire via COMTEX/ -- Aethlon Medical, Inc. AEMD +22.68%  , the pioneer in developing selective therapeutic filtration devices to address infectious disease, cancer and other life-threatening conditions, reported today that the presence of Hepatitis C virus (HCV) is currently undetectable in all infected patients that have been treated with the Aethlon Hemopurifier® in combination with peginterferon+ribavirin (PR) drug therapy and monitored for at least ninety days.

In a study conducted at the Medanta Medicity Institute (Medicity), HCV-infected individuals were enrolled to receive up to three, six-hour Hemopurifier® treatments during the first three days of PR drug therapy. The Medicity is a $360 million multi-specialty medical institute established to be a premier center for medical tourism in India. The Aethlon Hemopurifier® is a first-in-class medical device that selectively targets the rapid clearance of HCV from the entire circulatory system to improve benefit, dose, duration and tolerability of drug therapies.

In the Medicity study, Aethlon reported that Hemopurifier® therapy has been well tolerated and without device-related adverse events in nine treated patients. Of these nine patients, six patients were infected with HCV genotype-1; two patients were infected with HCV genotype-3; and one patient was infected with HCV genotype-5. Of the nine reported patients, seven have been monitored for more than ninety days. All seven currently maintain undetectable viral load, including three patients who have been monitored for 48-weeks. Two patients initiated Hemopurifier® therapy on April 18th and April 30th, and therefore have not yet been monitored for extended viral load suppression.

The Immediate Impact of Hemopurifier® Therapy

In addition to demonstrating safety and early efficacy against multiple HCV genotypes, a clinical objective of the Medicity study was to evaluate whether the Hemopurifier® could accelerate HCV eradication to levels associated with treated patients who achieve the highest rate of viral cure, including individuals that previously failed or relapsed PR drug regimens. In the study, Aethlon observed that viral load depletion during the Hemopurifier® + PR drug therapy phase was greatest in hard-to-treat genotype-1 patients with high viral load. In one treated patient, baseline HCV RNA dropped from 5,800,000 IU/ml to 1,840 IU/ml when measured after the third day of Hemopurifier® + PR therapy, representing a 3.49 log or 99.96% reduction of viral load. In another patient, baseline HCV RNA dropped from 8,760,000 IU/ml to 4,665 IU/ml when measured on day-3, representing a 3.27 log or 99.96% reduction. By contrast, a moderate viral load Hemopurifier® patient with baseline HCV RNA of 1,340,000 IU/ml dropped to 54,900 IU/ml when measured on day-3, representing a 1.38 log or 95.9% reduction.

As a point of reference, the landmark IDEAL Study of 3,070 HCV genotype-1 patients documented that less than 5% of treated patients will achieve a 2-log or greater reduction of viral load when measured 7-days after the start of PR drug therapy. While the IDEAL study did not report day-3 viral load, a 2-log+ reduction at day-7 is a rare occurrence defined as an immediate virologic response (IVR). The IDEAL study confirms the viral cure or sustained virologic response rate of IVR patients to be greater than 90%. Based on Medicity treatment outcomes, Hemopurifier® therapy had a significant impact in accelerating HCV eradication in high viral load patients.

Capacity of the Hemopurifier® to Capture HCV During Treatment

As the result of discussions with reviewers at the Center for Devices and Radiological Health (the FDA branch responsible for approving medical devices in the US), Aethlon recently expanded the Medicity protocol to establish a data point that would quantify the amount of HCV captured within the Hemopurifier® during a single treatment. In one analyzed cartridge, researchers recovered and measured that approximately 300 billion (300,000,000,000) copies of HCV had been captured within the Hemopurifier® during a single six-hour treatment at the Medicity. Beyond the impact of inhibiting progeny virus replication, the viral capture data point defines the contribution Hemopurifier® therapy can provide to current and future antiviral drug treatment regimens. Aethlon considers this data point to be unprecedented as the previous ability to measure the benefit of HCV therapies has primarily been limited to measuring changes in the amount of virus that can be detected in circulation.

Next Steps

As a result of Hemopurifier® + PR therapy outcomes, Aethlon has requested permission from the Medicity internal review board (IRB) to begin offering Hemopurifier® therapy to HCV-infected individuals that reside outside of India. The Company has also requested IRB permission to expand the treatment protocol to allow for up to seven Hemopurifier® treatments to be administered during the first week of PR drug therapy. Based on previous three-treatment protocol outcomes, Aethlon anticipates an expanded Hemopurifier® dosing schedule could establish new milestones for early undetectable viral load achievement. The Company also disclosed it will resubmit an investigational device exemption (IDE) which incorporates the Medicity data as part of its effort to gain FDA approval to initiate clinical programs in the U.S.

It is estimated that approximately 4 million Americans and 170 million people worldwide are infected with HCV, which leads to chronic liver disease or cirrhosis, and is the leading cause of liver transplant in the U.S. To date, almost 100 Hemopurifier® treatments have been administered in human studies. Previously, studies of the Hemopurifier® have been conducted at the Apollo, Fortis, and Sigma New Life hospitals in India. These studies demonstrated that Hemopurifier® therapy could safely reduce viral load in both HIV and HCV-infected dialysis patients without the administration of antiviral drug therapies. The Medicity study represents the first Hemopurifier® study in non-dialysis patients. In vitro studies have further validated the ability of the Hemopurifier® to capture a broad-spectrum of viral pathogens classified as bioterror or pandemic threats.

  1. Such a therapy could become an excellent way of reducing viral load during the anhepatic phase of liver transplantation for HCV cirrhosis thus reducing the risk of HCV recurrence post transplant. Together with Directly acting antivirals, this could be the way forward in managing post transplant HCV.
