Study shows drug may eliminate need for HCV genotype testing altogether
A new Gilead Sciences drug combination that targets six genotypes of the hepatitis C virus (HCV) has achieved promising results in four international phase III clinical studies.
Gilead has announced results from ASTRAL-1, ASTRAL-2, ASTRAL-3, and ASTRAL-4. The studies evaluated a once-daily, fixed-dose combination of the nucleotide analog polymerase inhibitor sofosbuvir (SOF) with velpatasvir (VEL), an investigational pan-genotypic NS5A inhibitor, for the treatment of genotype 1 to 6 chronic HCV infection.
In the ASTRAL-1, ASTRAL-2, and ASTRAL-3 studies, 1,035 patients with genotype 1 to 6 HCV infection received 12 weeks of SOF/VEL. Among these patients, 21%% had compensated cirrhosis and 28% had failed prior treatments. The ASTRAL-4 study randomized 267 patients with decompensated cirrhosis (Child-Pugh class B) to receive 12 weeks of SOF/VEL with or without ribavirin (RBV), or 24 weeks of SOF/VEL. The primary endpoint for all studies was a sustained virological response at week 12 post-treatment (SVR12)

U.S. Food and Drug Administration Grants Fast Track Designation to Can-Fite's CF102 in the Treatment of Liver Cancer
PETACH TIKVA, Israel, Sept. 17, 2015 /PRNewswire/ -- Can-Fite BioPharma Ltd. (NYSE MKT: CANF) (TASE:CFBI), a biotechnology company with a pipeline of proprietary small molecule drugs that address inflammatory and cancer diseases, today announced the U.S. Food and Drug Administration (FDA) has granted the Company's drug candidate CF102 Fast Track designation as a second line treatment for hepatocellular carcinoma (HCC), the most common form of liver cancer. CF102 had already received the FDA's Orphan Drug designation.
Can-Fite is currently conducting a Phase II study for this indication in the U.S., Europe and Israel. The randomized, double blind, placebo controlled study is expected to complete enrollment by the end of the first half of 2016 in 78 patients with Child-Pugh Class B cirrhosis who failed the only FDA approved drug on the market, Nexavar® (sorafenib). Patients are treated twice daily with 25 mg of oral CF102, which has been found to be the most efficacious dose in Can-Fite's earlier Phase I/II study resulting in the longest overall survival time, with excellent safety results.
Fast Track, aimed at getting important new drugs that meet an unmet need to patients earlier, is expected to expedite the development of CF102. Drugs that receive Fast Track designation benefit from more frequent meetings and communications with the FDA to review the drug's development plan to support approval. It also allows the Company to submit parts of the New Drug Application (NDA) on a rolling basis for review as data becomes available. Since the Fast Track Program started, from March 1998 through June 30, 2015 a total of 318 Fast Track applications have been received by the FDA. The FDA has granted 202 of them, and denied 110, with 6 more pending.
"We are very pleased that the FDA recognizes the potential for CF102 to treat HCC patients who have tried, and not been responsive to Nexavar, the only FDA approved drug currently on the market for this indication," stated Can-Fite CEO Dr. Pnina Fishman. "We consider Fast Track designation to be a major catalyst for our CF102 development program and we believe it could shorten our time to market for CF102, thereby making a considerable difference for patients."
According to Global Industry Analysts, the global market for liver cancer drugs is projected to exceed $2 billion in 2015. Nexavar® annual sales, as reported by Bayer, were €773 million in 2014.
About CF102
CF102 is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). A3AR is highly expressed in tumor cells whereas low expression is found in normal cells. This differential effect accounts for the excellent safety profile of the drug. In Can-Fite's pre-clinical and clinical studies, CF102 has demonstrated a robust anti-tumor effect via deregulation of the Wnt signaling pathway, resulting in apoptosis of liver cancer cells.
About Can-Fite BioPharma Ltd.

Researchers find HCV treatment uptake declined over time among HIV/HCV coinfection
Note: You may be required to sign up to read this article:
In the Swiss HIV Cohort Study, researchers found that hepatitis C virus infection treatment uptake over the last 13 years has been low and many patients co-infected with HIV and hepatitis C remained untreated since 2013.
“The Swiss HIV Cohort Study offers an ideal platform to study the natural course of HCV infection and long-term influence of HCV treatments in a nationwide representative population of HIV-infected patients,” the researchers wrote in the Journal of Hepatology. “We aimed to assess the changes in epidemiology, clinical course and therapy of HCV infection between 2001 and 2013 and to characterize the population who remains eligible for the new HCV treatment options by the end of 2013.”
Of 12,401 patients, 17% were positive for HCV RNA (n = 2,107) and 23.8% were seropositive for HCV. Thirty-percent of the HCV RNA-positive patients (n = 636) began therapy with an incidence of 5.8 per 100 person-years (95% CI, 5.3-6.2). Of the patients treated with pegylated interferon and ribavirin, 50% achieved sustained virologic response, which represented 15% of all participants with replicating HCV infection, according to the research. Also, of the 636 treated patients, 11% were treated twice and 2% were treated at least 3 times.

Managing Hepatitis C: Advances in treatment & evaluation
Improvements to the efficacy and side effects of hepatitis C medications have simplified the disease management calculus, tipping the scales towards treatment.
The availability of effective oral medication has also raised the bar for clinicians: is there a way to make similar progress in the evaluation side? What would it take to stage the disease quickly, safely, and without discomfort for the patient?
The stiffness of the patient's liver tissue, categorized at a certain stiffness as "fibrosis," provides hepatologists important diagnostic information about the extent and stage of hepatitis C. Liver biopsy has long been the gold standard for obtaining this information. However, biopsies are time-consuming invasive procedures that routinely cause patients pain and, in some rare instances, lead to greater complications such as internal bleeding. These procedures take up clinical staff time, necessitate bed space, and incur instrument and room sterilization costs. Lastly, they are subject to not insignificant sampling limitations, as each biopsy takes only a small sample from a large organ.

What We Talk About When We Talk About Hepatitis C
Since 2007, more people have died every year from hepatitis C than from HIV. Fortunately, the latest hepatitis C medications can cure nearly everyone in a relatively quick, easy fashion. So, if it is so easy to cure hepatitis C, why haven't we?
Ostensibly, it is because of the cost. At $1125 a pill for Gilead Sciences' drug Harvoni, a 12-week course of hepatitis C treatment would amount to $94,500. Trying to manage these costs, many state Medicaid programs and insurance companies have severely restricted access to treatment. You save money if you deny treatment to people, and dead people cost nothing.
This means that although we can cure hepatitis C, we aren't. Under many insurance plans, patients have to prove that they have cirrhosis. In short, treatment is approved when liver damage has progressed to its worst stage. It is like refusing to pay for diabetes drugs until the patient is blind or minus a few toes.

Achillion Reports 100% SVR12 From Second Cohort of Patients in the Previously-Completed Six Week Phase 2 Trial Evaluating Odalasvir (ACH-3102) and Sofosbuvir for Genotype 1 HCV ("Proxy Study")
- 100% SVR12 reported for all patients treated for six- (n=18) or eight-weeks (n=12) —
- Odalasvir (ACH-3102) is the subject of an exclusive, worldwide development and commercialization license granted to Janssen -
NEW HAVEN, Conn., Sept. 17, 2015 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today announced additional interim results from a Phase 2 study evaluating odalasvir (also known as ACH-3102), a NS5A inhibitor, in combination with sofosbuvir, without ribavirin, for either six or eight weeks of treatment in patients with treatment-naïve genotype 1 chronic hepatitis C virus (HCV) infection. Of the patients treated for six weeks in this cross-over cohort, 100 percent (n=6/6) remained HCV RNA undetectable twelve weeks after completing therapy (SVR12). Previously, Achillion reported results from this study including 100 percent SVR24 for the initial cohorts including 12 patients treated for eight weeks and 100 percent SVR24 for 12 patients treated for six weeks.
In May 2015, Achillion announced it had granted Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, an exclusive, worldwide license to develop and, upon regulatory approval, commercialize HCV products and regimens containing one or more of Achillion's HCV assets which include odalasvir, ACH-3422, and sovaprevir.
ACH-3102 - 017: Phase 2 pilot study evaluating six- and eight-weeks of treatment in combination with sofosbuvir for genotype 1 treatment-naïve HCV
Achillion conducted a Phase 2, open-label, randomized, partial-crossover study to evaluate the efficacy, safety, and tolerability of eight weeks or six weeks of odalasvir and sofosbuvir, a marketed nucleotide polymerase inhibitor, without ribavirin, in treatment-naïve genotype 1 HCV-infected patients. The primary objective of the study was determination of sustained viral response 12 weeks (SVR12) after the completion of therapy. Eighteen patients were initially enrolled, including six observational patients (group 1). Twelve patients completed eight weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily while observational patients received no drug during this phase of the trial. Ten of the 12 patients receiving eight weeks of treatment had genotype 1a HCV. At baseline, the median HCV RNA was 7.15 log10 (range 5.5 — 7.8 log10). Of the 12 patients, 100 percent achieved SVR24. Odalasvir and sofosbuvir were well tolerated with no significant adverse events, ECG findings, or lab abnormalities observed during treatment.
Following achievement of the pre-specified response rate of 100 percent, the six observational patients plus six additional patients (group 2) were enrolled and received six weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily. Median HCV RNA at baseline was 6.95 log10 (range 6.2 — 8.0 log10) and six patients had GT 1a HCV. Of the 12 patients, 100 percent achieved SVR24.
Six additional rollover patients (group 3), enrolled into the final cohort, also received six weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily. Baseline characteristics included five of six patients with genotype 1a HCV, four of six patients with non-CC IL28B (two patients with IL28B TT), and a median baseline HCV RNA of 6.32 log10 IU/ml (range 6.0 — 7.3 log10 IU/ml). In all, a total of 18 patients (group 2 and 3) received six weeks of treatment and all subjects, 100 percent, achieved SVR12.
About the Achillion Worldwide HCV Collaboration with Janssen
On May 19, 2015, Achillion announced it had granted Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, an exclusive, worldwide license to develop and, upon regulatory approval, commercialize HCV products and regimens containing one or more of Achillion's HCV assets which include odalasvir (ACH-3102), ACH-3422, and sovaprevir. A key objective of the collaboration is to develop a short-duration, highly effective, pan-genotypic, oral regimen for the treatment of HCV. Achillion announced on August 3, 2015 that Alios Biopharma Inc., part of the Janssen Pharmaceutical Companies (Janssen) had initiated a Phase 1 clinical trial to evaluate the potential effect of simeprevir and odalasvir on the pharmacokinetics of AL-335 in healthy volunteers. Janssen previously stated its goal of initiating Phase 3 development with a triple regimen for HCV by early 2017.
About HCV
The hepatitis C virus (HCV) is one of the most common causes of viral hepatitis, which is an inflammation of the liver. It is currently estimated that more than 150 million people are infected with HCV worldwide including more than 5 million people in the United States. Three-quarters of the HCV patient population is undiagnosed; it is a silent epidemic and a major global health threat. Chronic hepatitis, if left untreated, can lead to permanent liver damage that can result in the development of liver cancer, liver failure or death. Few therapeutic options currently exist for the treatment of HCV infection.
