New mouse viruses could aid hepatitis research

Newly discovered mouse viruses could pave the way for future progress in hepatitis research, enabling scientists to study human disease and vaccines in the ultimate lab animal. In a study to be published in mBio, the online open-access journal of the American Society for Microbiology, scientists describe their search for viruses related to the human hepatitis C virus (HCV) and human pegiviruses (HPgV) in frozen stocks of wild mice. The discovery of several new species of hepaciviruses and pegiviruses that are closely related to human viruses suggests they might be used to study these diseases and potential vaccines in mice, without the need for human volunteers. …read more

Gilead Submits New Drug Application to U.S. FDA for Sofosbuvir for the Treatment of Hepatitis C


— Sofosbuvir Would Form Basis of First All-Oral Regimen for HCV Genotype 2 and 3 Patients, and Interferon-Sparing Regimen for Genotype 1 Patients —

FOSTER CITY, Calif.–(BUSINESS WIRE)– Gilead Sciences (NAS: GILD) today announced that the company has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for approval of sofosbuvir, a once-daily oral nucleotide analogue for the treatment of chronic hepatitis C virus (HCV) infection. The data submitted in this NDA support the use of sofosbuvir and ribavirin (RBV) as an all-oral therapy for patients with genotype 2 and 3 HCV infection, and for sofosbuvir in combination with RBV and pegylated interferon (peg-IFN) for treatment-naïve patients with genotype 1, 4, 5 and 6 HCV infection.

Chronic HCV infection affects up to four million Americans, particularly individuals born between 1946 and 1964. The disease is the leading cause of liver cancer and liver transplantation in the United States. Treatment for HCV currently includes 24-48 weeks of therapy with peg-IFN, which has to be injected and is associated with significant side effects, leaving some patients unable to complete therapy. If approved, sofosbuvir would shorten HCV therapy to 12 to 16 weeks, and depending on the genotype, would either eliminate or reduce the duration of peg-IFN injections.

“Current therapies are not suitable for large numbers of patients with HCV infection, and are challenging to take and tolerate,” said John C. Martin, PhD, Chairman and Chief Executive Officer of Gilead Sciences. “Sofosbuvir’s antiviral potency, safety profile and once-daily administration have the potential to improve cure rates by simplifying and shortening therapy for patients with this disease.”

The sofosbuvir NDA is supported primarily by data from four phase 3 studies, NEUTRINO, FISSION, POSITRON and FUSION, in which 12 or 16 weeks of sofosbuvir-based therapy was found to be superior or non-inferior to currently available treatment options or historical controls, based on the proportion of patients who had a sustained virologic response (HCV undetectable) 12 weeks after completing therapy (SVR12). Patients who achieve SVR12 are considered cured of HCV.

Gilead plans to file for regulatory approval of sofosbuvir in other geographies, including the European Union, in the second quarter of 2013. The European Medicines Agency (EMA) …read more

Gilead Announces Update on Phase 3 Study of Oral Fixed-Dose Combination of Sofosbuvir and Ledipasvir for Genotype 1 Hepatitis C Patients


— Enrollment in ION-1 Study Continues Following Planned DSMB Review —

FOSTER CITY, Calif.–(BUSINESS WIRE)– Gilead Sciences, Inc. (NAS: GILD) today provided an update on ION-1, a Phase 3 clinical trial evaluating a once-daily fixed-dose combination of the nucleotide sofosbuvir and the NS5A inhibitor ledipasvir with and without ribavirin (RBV) for 12 or 24 weeks among treatment-naïve genotype 1 patients with hepatitis C virus (HCV) infection (n=800). A planned review by the study’s Data and Safety Monitoring Board (DSMB) of safety data from 200 patients in all four arms and of SVR4 rates (sustained virologic response four weeks after completion of therapy) from 100 patients in the two 12-week duration arms concluded that the trial should continue without modification. This recommendation is based upon the observed SVR4 rates exceeding the predefined threshold of 60 percent and the absence of significant safety issues. Enrollment of the remaining 600 patients in ION-1 is now underway.

Sofosbuvir/ledipasvir is also being evaluated in a second Phase 3 study, ION-2, initiated in January 2013, which is now fully enrolled. ION-2 is evaluating sofosbuvir/ledipasvir with RBV for 12 weeks, and with and without RBV for 24 weeks, among 400 treatment-experienced genotype 1 HCV patients. Participants in this study failed to respond to past therapy containing pegylated interferon (peg-IFN) or peg-IFN plus a protease inhibitor.

Sofosbuvir, ledipasvir and the sofosbuvir/ledipasvir fixed-dose combination are investigational products and their safety and efficacy have not yet been established.

Roche Wins Expanded European Approval for Pegasys

By Dan Carroll, The Motley Fool

Filed under:

The European Medicines Agency, or EMA, has awarded Big Pharma Roche expanded approval for its antiviral Pegasys, alongside ribavirin, in treating chronic hepatitis C virus, or HCV. The EMA‘s expanded approval will now allow Roche to treat HCV-positive children aged 5 and older with the drug who have not yet begun treatment, according to a statement from the company.

Roche first won European approval for Pegasys in treating adults with chronic HCV more than a decade ago; regulators in China and the U.S. have approved it as well. Around 65,000 European children suffer from chronic HCV; while Roche states that many sufferers of the disease show few if any symptoms, it is progressive and can afflict patients with life-threatening ailments such as liver damage.

Dr. Hal Barron, Roche’s chief medical officer and global product development Head  talked about the new indication’s benefit for children with the disease, saying in the release: “Hepatitis C can ultimately lead to the development of advanced liver disease if left untreated. This approval provides doctors and parents of children as young as five with a treatment combination for this infection.”

BioLineRx Receives Approval from French Regulatory Authorities to Commence a Phase I/II Clinical Trial for BL-8020, an Oral, Interferon-Free Treatment for Hepatitis C


– Interim results are expected by the end of 2013 –

JERUSALEM–(BUSINESS WIRE)– BioLineRx (NAS: BLRX) (TASE:BLRX), a biopharmaceutical development company, announced today that it has received approval from the French regulatory authorities to commence a Phase I/II trial for BL-8020, an orally available, interferon-free treatment for the Hepatitis C virus (HCV). The study is an open-label trial to evaluate the efficacy, safety and tolerability of BL-8020 in patients infected with HCV. It will be conducted at two clinical sites in France and will include HCV-infected patients of any genotype who have previously failed or relapsed following treatment with the standard-of-care.

“We are excited about the upcoming initiation of clinical trials for our first anti-HCV agent, BL-8020. The Phase I/II trial will be led by Prof. Stanislas Pol, M.D., Ph.D, from Hôpital Cochin in Paris, and Prof. Marc Bourliere, M.D., from Hôpital Saint Joseph in Marseille, both prominent international leaders in the HCV field,” stated Dr. Kinneret Savitsky, CEO of BioLineRx. “Based on BL-8020’s pre-clinical results, its unique mechanism of action and synergistic effect, we have high hopes for this drug especially when combined with other available Hepatitis C drugs. We look forward to the interim results from the Phase I/II trial expected towards the end of 2013.”

BL-8020 is an orally available HCV treatment with a unique mechanism of action, as compared to other currently used anti-HCV agents. This suggests pan-genotypic efficacy and the ability to be combined with other HCV therapeutics as part of an interferon-free regimen. BL-8020’s mechanism of action involves the inhibition of HCV-induced autophagy in the host cells. Autophagy is a mechanism by which cells degrade damaged or unnecessary cellular components, including invading viruses. However, HCV has found a way to take advantage of this mechanism in order to replicate inside the cell. By inhibiting this mechanism, BL-8020 reduces the ability of HCV to replicate.

BL-8020’s safety and efficacy have been demonstrated in a number of pre-clinical studies. These studies have shown that BL-8020 has a synergistic effect with other anti-HCV agents. This effect on other therapies is likely to increase their potency and reduce the numerous adverse effects often associated with these drugs by enabling utilization of lower dosages. …read more

BioLineRx Reports Year End 2012 Financial Results

JERUSALEM–(BUSINESS WIRE)– BioLineRx Ltd. (NAS: BLRX) (TASE: BLRX), a biopharmaceutical development company, today reported its results for the year ended December 31, 2012.

“BioLineRx is rapidly approaching a significant landmark in the evolution of the Company,” stated Kinneret Savitsky, Ph.D., CEO of BioLineRx. “We are eagerly anticipating the interim analysis of the on-going CLARITY Phase 2/3 trial for our lead compound, BL-1020 for schizophrenia, which we expect to receive next week. The analysis will include a recommendation by an independent Data Monitoring Committee (DMC) regarding the number of additional patients needed in order to reach statistical significance on the cognitive effect of BL-1020 compared to Risperidone. Although the data from the ongoing study is completely confidential, based on promising evidence received in previous clinical and pre-clinical trials, we hope the information received will provide a clear indication regarding the strength of the cognition improvement signal, thereby putting us in a stronger position to out-license BL-1020 and move towards commercializing the compound.”

“The PRESERVATION I pivotal CE mark registration trial for our other lead compound, BL-1040 for ventricular remodeling post-AMI, which is being carried out by Ikaria, Inc., continues to progress on an accelerated basis. Currently, there are 15 sites recruiting in Australia, Belgium, Canada, Israel and Spain, and results from the trial are expected in 2014.”

“In addition, our Phase 2 proof-of-concept study for BL-7040, an oral treatment for Inflammatory Bowel Disease (IBD), is nearing completion. This is an open-label study to evaluate the efficacy, pharmacodynamics, safety and tolerability of BL-7040 in up to 30 patients with moderately active ulcerative colitis, a type of IBD. This trial is being carried out at five sites in Israel, and we are expecting to announce results in April 2013.”

“During 2012, we in-licensed several high-profile therapeutic compounds that are already advancing towards clinical testing. This includes BL-8040, a Phase 2-ready drug for the treatment of acute myeloid leukemia (AML) and other hematological cancers. The interest in this program is high, and we have recently signed an agreement with one of the premier cancer centers in the world, MD Anderson Cancer Center in Houston, Texas, to be the lead site in the trial. We are currently in negotiations with two other U.S.-based, world-class facilities for their participation in the trial as well,” continued Dr. Savitsky.

“At the beginning of 2012, we entered the competitive HCV market with the in-licensing of two orally-available compounds for the treatment of Hepatitis C from world renowned experts …read more
