Vertex Drug for Hepatitis C Shows Durable Virus-Killing Ability in Tough-to-Treat Patients

Xconomy Boston — 

More data is rolling in from Vertex Pharmaceuticals on its lead drug for hepatitis C, and it looks like the medicine is continuing to live up to its own high expectations. The Cambridge, MA-based company said today that telaprevir’s effect on killing the virus is remaining durable on follow-up analysis, and the drug appears to just about as good in a more convenient twice-daily pill form instead of its standard three-times-a-day dosing schedule.

The data dump came in front of a prime audience of physicians attending the American Association for the Study of Liver Disease annual meeting today in San Francisco. The results appear to match up pretty consistently with what Vertex has reported previously, which I wrote about in this advance story.

To recap what’s at stake, telaprevir is aiming to be a first-in-class protease inhibitor against hepatitis C, a chronic liver disease. If it can deliver in the final stage of clinical trials, it will change the standard of treatment for the disease. An estimated 3.2 million people in the U.S. have hepatitis C infections, and about 170 million have it worldwide. Telaprevir must be taken with a pair of standard drugs, pegylated interferon alpha and ribavirin, which cause flu-like symptoms and must be taken for almost a year. The Vertex drug is highly anticipated, though, because it has shown in earlier trials that it can almost double the cure rate for patients when added to standard therapy, and in half the time. If approved, the product could generate $2.6 billion in U.S. sales in 2013, according to Rachel McMinn, an analyst with Cowen & Co. in San Francisco.

“These are strong and striking early results,” says Freda Lewis-Hall, Vertex’s executive vice president for medicines development.

In the spirit of helping you keep all this data straight, because there’s a lot of it, we’re breaking this down into bite-size chunks. .

—The ‘107 study. This trial of patients who didn’t respond to previous treatment, produced data from more patients who were followed over a longer period than was previously reported. Researchers found that 68 of 104 patients, or about two-thirds, who got telaprevir along with standard drugs had no evidence of the virus in their blood after four weeks. That effectiveness appeared to be long-lasting. Researchers found that 41 of 71 patients (58 percent) followed for 24 weeks still had no evidence of the virus in the blood. Importantly, telaprevir is showing that it can wipe out the virus about 43 percent of the time in the toughest patients of all to treat—those who didn’t respond at all to a prior round of therapy.

The last time Vertex reported results from this trial, at a European meeting in April, it didn’t have any follow-up data that extended this long, or such strong data for what are called “null responder” patients. Of course, there were side effects, though. About 8 percent of patients dropped out of the study because of adverse events, with about half of them quitting because they developed a rash, the company said.

—The C208 study. This trial is about convenience for patients. … Next Page »

    Sam, Hi I just finished my 12 week on Interfearon, after blood work results I’m told my viral load # is out of range & was discontiued from treatment. In twelve weeks it went down from 423,000 to 97,000 still not good enough for them, Right now I still have three week of medicine left, And plan on taking that untill gone. So both Ribivin & pegasys are still at full strenth in my system, I think that I would be an excellant canidate for your Vertex study, Thank you for any help you can give me………….

    Hello, My name is Karla, I was diagnosed with Hepc in 2000 while pregnant with my son, you can imagine how devastating that was for me, I went into a deep depression for a few years in denial and finally underwent treatment with interferon and ribavarin. Unfortunately, it was no help. I live in Cedar Hill, TX and I would like to become a candidate for the trial drug. Thankyou for any help you can offer me.

    Hi Luke,

    Thanx for your reports regarding Telaprevir.
    Perhaps I could be of assistance in the proving of this new product. I am a 54 year old male who was diagnosed with HepC Type 1A in October of 2006. High viral counts are evidence that the virus has been active in my system for many years. Since discovery of my ailment I have been reporting to my gatrointestinal specialist regularly 4 times a year for a blood draw and analysis. A liver biopsy in November of 06 revealed minimal damage with no bridging and ultra sounds reveal nothing worthy of remark.

    Blood draw of 2/5/09 indicated ALT of 47
    Viral count: HCV RNA PCR was 3,160,000 IU/ml
    6,320,000 copy/ml.

    I have received no treatment to date aside from 2 months of Ursodiol, observation and total abstinence from alcohol.

    I can be contacted by email should I be considered a valuable candidate for study.

    Eric Gustafson

    Approximately 4 years ago I went through a 7 month interferon bout with no visible success. I do drink moderately and after the unsuccessful bout with interferon I began drinking again. I since have quit drinking and would be game for trying telaprevir for study. I am told by my doctor that my Hepatitis C is a tough kill. Like to find out if that’s true.

    Please send me information on Telaprevir thank you

  11. Here are a couple of places to look for updated information on hepatitis C clinical trials.

    Just wish to point some of you in the right direction.
    Getting into a trial can be most certainly a life altering experience.
    Some members in our forum have been in the Vertex Trial and have cleared the virus / still clear 6 months after completing treatment or SVR. Cured by some standards.

    You may wish to talk to our friends in our chat room or on our message boards.

    If you go to our “Treatment Stories” Section of our site you will be able to follow some of these people. Because we have so many people clearing the virus on standard HCV therapy and new therapies not all of them are documented on our web site.

    Our site has been around since 2001 and I
    myself cleared the virus SVR in a trial back in 1999.

    We have more then a few people that have treated successfully with the New Inhibitors since 2008. Some of these people are even in the follow up studies.

    Hope we can help

Once in 2001 for 11 months rabivirin and 1 weekly shot, second time shots everyday for 11 months with pills, and still had to be taken off just short of completeing TX, with a viral load of millions of millions.
