FDA Panel Backs Approval Of Vertex's Hepatitis C Drug Telaprevir

    WASHINGTON -(Dow Jones)- A Food and Drug Administration panel unanimously backed the approval of Vertex Pharmaceuticals Inc.'s (VRTX) proposed hepatitis C-drug telaprevir, saying it showed strong effectiveness, a day after also endorsing a similar product from Merck & Co. (MRK).

    The panel of non-FDA medical experts voted 18-to-0 on a question that asked whether the available data support approval of the telaprevir in combination with other hepatitis C drugs, pegylated interferon and ribavirin. The vote amounts to a recommendation that the agency approve telaprevir. The FDA usually follows the advice of its advisory panels but isn't required to.

    Wall Street analysts widely expect FDA to approve telaprevir and Merck's boceprevir as both have demonstrated significant effectiveness in improving the cure rates in patients who use standard therapy for hepatitis C. One panel member called telaprevir "stunning advance" in the treatment of hepatitis C.

    Both drugs are known as protease inhibitors and are designed to block an enzyme that helps the hepatitis C virus replicate. Vertex owns the North American rights to the telaprevir and would get a royalty on overseas sales from partner Johnson & Johnson (JNJ).

    The approval of the drugs, which could come in May, would pit Cambridge, Mass., Vertex against Merck, one of the world's biggest drugmakers, in a market that could triple to $12 billion after the introduction of the latest batch of drugs, according to Goldman Sachs.

    The two main studies Vertex submitted to the FDA in support of telaprevir showed more patients responded to treatment by achieving a so-called sustained virologic response -- essentially a cure -- and in a shorter period of time than current hepatitis-C therapy. A third study looked at extending treatment with a telaprevir-based regimen.

    One study that involved previously untreated patients showed 79% of patients receiving telaprevir in addition to current standard treatments of pegylated interferon and ribavirin had a sustained virologic response compared to 46% of patients not receiving telaprevir as part of their treatment regimens. In some cases, patients were successfully treated in a total of 24 weeks rather than the current 48 weeks of hepatitis C therapy.

    The agency said the risks of telaprevir were associated with skin reactions, such as rash, and anemia. The agency said such side effects were "common, sometimes severe, and in some cases treatment limiting." Anemia is a decrease in the number of red-blood cells.

    Vertex said rashes was managed in most patients with antihistamines and topical corticosteriods. The company said the significantly higher effectiveness of telaprevir. "In all subject categories has the potential to offer many more patients the benefits of eradicating [hepatitis C] and achieving a viral cure," the company said.

    Hepatitis C is a liver disease caused by infection with the hepatitis C virus, which is transmitted through contaminated blood. The infection can cause liver failure, liver cancer and is the leading cause of liver transplants, FDA said. About 3.2 million Americans are infected with hepatitis C.

    BOSTON (MarketWatch) -- An advisory panel of the U.S. Food and Drug Administration has voted to recommend the agency approve Vertex Pharmaceuticals' VRTX hepatitis C drug telaprevir, according to reports. Shares of Vertex were halted Thursday pending the outcome of the meeting. While the FDA is not bound to the recommendations of its panels, it generally follows them. On Wednesday, the same panel voted to recommend the approval of Merck's hepatitis C drug boceprevir.

    aardig volume vandaag, en een kleine plus. Benieuwd of bovenstaand nieuws voor de langere termijn nog van invloed zal zijn op de koers van Octo
    De markt calculeert de mogelijkheid in dat volgend jaar 2 extra fase 3 onderzoeken worden gedaan met de goedgekeurde virale middelen Telaprivir en Boceprivir. De produktie van Locteron in 2008 en 2009 heeft Octoplus ca 20 miljoen opgeleverd voor fase 2b. In fase 2b waren ca 150 patienten.
    Fase 3 onderzoek gaat om een veelvoud van het aantal patienten. Albufeiron in fase 3 werd op 2255 patienten getest.

    The Phase 3 studies, known as ACHIEVE 1 and ACHIEVE 2/3, evaluated albinterferon alfa-2b vs. peginterferon alfa-2a, in combination with ribavirin, for use in the treatment of interferon-naive patients with chronic hepatitis C. ACHIEVE 1 was conducted in patients infected with genotype 1 virus, and ACHIEVE 2/3 was conducted in patients with genotypes 2 and 3 virus. The two studies treated a combined total of 2255 treatment-naive patients

    Stel dat Biolex 3000 patienten nodig heeft voor drie fase 3 onderzoeken, betekent dit dat er 20 maal zoveel Locteron geproduceerd moet worden dan in fase 2b de komende 3 jaar, dat is een omzet van 400 miljoen over 3 jaar.

    Er zal ongetwijfeld synergie te behalen zijn met de hogere aantallen, maar dan nog gaat de omzet knallen de komende jaren.

    qua koers een mooie week gehad; koers ging van 1.25 naar 1.35...

    benieuwd naar de business update, deze zal ongetwijfeld komende week komen, anders zit deze te kort op de AvA lijkt me, dus in ieder geval weer een persbericht in mei

    hopelijk weer eens nieuws over OP-145, wat mijn inziens, een beetje in de vergetelheid raakt....
