RedHill Biopharma Provides 2016 Semi-Annual R&D Update
TEL-AVIV, Israel, Aug. 11, 2016 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (NASDAQ: RDHL) (TASE:RDHL) ("RedHill" or the "Company"), a biopharmaceutical company primarily focused on development and commercialization of late clinical-stage, proprietary, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, today provided an update on select research and development potential milestones and estimated timelines.
"RedHill continues to pursue its multiple-shots-on-goal strategy with a focus on advancing its three ongoing gastroenterology Phase III programs in the U.S., RHB-105 for H. pylori infection, RHB-104 for Crohn's disease and BEKINDA® for gastroenteritis, as well as additional Phase II programs, supported by a strong and debt-free balance sheet," stated Mr. Dror Ben-Asher, RedHill's Chief Executive Officer. "We continue to further enhance the overall robustness of our flagship Phase III programs and increase data collection in support of future potential new drug applications, while maintaining a substantially consistent cash burn through the end of 2017." Mr. Ben-Asher added, "In light of strong recruitment rates in the ongoing Phase II study with BEKINDA® for IBS-D, we are pleased to provide guidance, for the first time, on the estimated timing for top-line results, which are anticipated in mid-2017. RedHill is well-positioned for continued solid growth and we look forward to several Phase III and Phase II data points and other important milestones and potential catalysts expected in the coming months."
RHB-105 - H. pylori bacterial infection (confirmatory Phase III)
- Following the positive FDA meeting in April 2016, and in light of guidance received on the potential path for marketing approval, preparations continue for the confirmatory Phase III study with RHB-105 for the treatment of H. pylori infection. The two-arm, randomized, double-blind, active comparator confirmatory Phase III study is planned to be initiated in the fourth quarter of 2016 or in the first quarter of 2017, following completion of a supportive pharmacokinetic (PK) program. The study is planned to enroll approximately 440 patients in up to 50 clinical sites in the U.S.
The planned confirmatory Phase III study, along with the results from the successfully completed first Phase III study (the ERADICATE Hp study) and data to be obtained from a supportive PK program, are expected to support a U.S. New Drug Application (NDA) for RHB-105. The first Phase III clinical study with RHB-105 successfully met its primary endpoint of superiority over historical standard-of-care (SoC) eradication rate of 70%, with high statistical significance (p<0.001). The Phase III ERADICATE Hp study results demonstrated 89.4% efficacy in eradicating H. pylori infection with RHB-105. Notably, subsequent open-label treatment with SoC therapies of patients in the placebo arm of the Phase III ERADICATE Hp study demonstrated only 63% eradication rate, further supporting the potential superior efficacy of RHB-105 over SoC.
RHB-104 - Crohn's disease (Phase III) and multiple sclerosis (Phase IIa)
Crohn's disease - first Phase III study ongoing
- Approximately 200 subjects out of the planned total of 270 have been enrolled to date in the randomized, double-blind, placebo-controlled first Phase III study with RHB-104 for Crohn's disease (the MAP US study).
Interim data and safety monitoring board (DSMB) analysis is on track to take place in the fourth quarter of 2016 and RedHill remains blinded to the interim and ongoing results.
RedHill is currently reviewing a possible amendment to the Phase III MAP US study protocol intended to further enhance the overall robustness of the study, provide a more precise assessment of RHB-104's treatment effect, collect additional endoscopic mucosal healing data, further evaluate the Crohn's disease population enrolled and address retention and early terminations. No changes are planned to the primary endpoint of remission at week 26 or the study's 90% power. Taking into account a potential protocol amendment, completion of recruitment is expected in 2017 with no anticipated material impact on the Company's overall cash burn rate through the end of 2017. The Company expects to provide further details in the coming weeks, once plans are finalized.
Multiple sclerosis – Phase IIa study ongoing
- Top-line final results from the Phase IIa CEASE-MS study with RHB-104 for relapsing-remitting multiple sclerosis (RRMS) are expected in the fourth quarter of 2016, following the recently announced last patient follow-up visit in the study. In the first 24 weeks, patients enrolled in the CEASE-MS study received treatment with RHB-104 as an add-on therapy to interferon beta-1a and were then evaluated for an additional 24-week follow-up period during which they were treated with interferon beta-1a alone. Top-line interim results announced in March 2016, after completion of the 24-week treatment period, demonstrated positive safety and efficacy signals, including an encouraging relapse-free rate, Expanded Disability Status Scale (EDSS) scores and MRI results, which support further clinical development.
BEKINDA® (RHB-102) - acute gastroenteritis (Phase III) and IBS-D (Phase II)
Acute gastroenteritis and gastritis - Phase III study ongoing
- RedHill has implemented a protocol amendment to the ongoing Phase III study with BEKINDA® 24 mg for acute gastroenteritis (the GUARD study) to increase the safety data collected, so that the study results may support a potential NDA filing, as per FDA's recommendation. The study protocol now requires patients to remain in the emergency room for a longer follow-up period and perform an ECG (electrocardiogram) at the end of follow-up and prior to discharge. In light of this amendment, completion of patient enrollment in the randomized, double-blind, placebo-controlled Phase III GUARD study is currently expected in early 2017.
IBS-D - Phase II study ongoing
- Completion of patient enrollment in the ongoing randomized, double-blind, placebo-controlled Phase II study with BEKINDA® 12 mg for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) is expected in the first half of 2017, with top-line results expected mid-2017.
YELIVA™ - Phase I/II studies for multiple oncology and inflammatory indications
- A Phase I/II study with YELIVA™, a first-in-class SK2 selective inhibitor, for the treatment of refractory or relapsed multiple myeloma is planned to be initiated later this year at Duke University Medical Center. The study is supported by a $2 million grant from the National Cancer Institute (NCI) awarded to Apogee Biotechnology Corp. (Apogee) in conjunction with Duke University, with additional support from RedHill.
- A Phase II study with YELIVA™ for the treatment of advanced hepatocellular carcinoma is planned to be initiated later this year. The study will be conducted at the Medical University of South Carolina (MUSC) Hollings Cancer Center and additional clinical centers in the U.S. It is supported by a $1.8 million grant from the NCI awarded to MUSC, intended to fund a broad range of studies on the feasibility of targeting sphingolipid metabolism for the treatment of a variety of solid tumor cancers, including the Phase II study with YELIVA™, and will be further supported by additional funding from RedHill.
- A Phase I/II clinical study to evaluate YELIVA™ as a radioprotectant to prevent mucositis in cancer patients undergoing therapeutic radiotherapy is planned to be initiated later this year.
- A Phase I/II clinical study evaluating YELIVA™ in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) was initiated at the Louisiana State University Health Sciences Center (LSUHSC) in New Orleans in June 2015 and was recently put on administrative hold, pending a protocol amendment aimed at improving overall recruitment prospects. The study is supported by a grant awarded to Apogee from the NCI, as well as additional support from RedHill.
- Following the successful Phase I study with YELIVA™ in patients with advanced solid tumors, and in light of the drug's novel mechanism of action, RedHill is evaluating potential clinical studies for additional oncology and inflammatory indications, as well as potential collaboration opportunities to evaluate YELIVA™ as an add-on therapy.
RHB-106 - encapsulated bowel preparation, exclusive worldwide rights licensed to Salix Pharmaceuticals (now Valeant Pharmaceuticals International)
- The exclusive worldwide rights to RedHill's RHB-106 encapsulated bowel cleanser, as well as additional related rights (RHB-106 Program), were licensed to Salix Pharmaceuticals Ltd. in 2014, which was acquired by Valeant Pharmaceuticals International Inc. (Valeant) in 2015. Valeant remains fully responsible for the development of the RHB-106 Program and for future potential commercialization. RedHill has recently been informed by Valeant that, as a result of Valeant's greater focus on R&D investment, the development of the RHB-106 Program continues to be explored.
- Earlier this week, Valeant highlighted their commitment to bolstering their R&D and commercial offering and enhance their gastrointestinal business with the acquisition of the North American rights to a powder for oral solution bowel cleanser (NER1006) from Norgine B.V.
Ebola virus disease therapy (RedHill's proprietary experimental therapy) - NIH collaboration
- Initiation of the research collaboration with the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), is expected in the fourth quarter of 2016. The new study is intended to evaluate RedHill's proprietary experimental therapy for the treatment of Ebola virus disease and follows encouraging results from preliminary non-clinical studies conducted in conjunction with NIAID. Top-line results from the study are expected in 2017.
RIZAPORT® (RHB-103) - acute migraines (approved for marketing in Germany)
- Re-submission of the RIZAPORT® U.S. NDA to the FDA is expected in the first half of 2017. RIZAPORT® was approved for marketing in Germany under the European Decentralized Procedure (DCP) in October 2015 and a first commercialization agreement was recently signed with Grupo JUSTE S.A.Q.F for Spain and additional potential territories.
RedHill continues discussions with additional potential commercialization partners for RIZAPORT® in the U.S., Europe and other territories.
MESUPRON – First-in-class small molecule for oncology indications (Phase II-stage)
- RedHill's current development program for MESUPRON includes nonclinical studies as well as re-analysis of certain prior clinical data. MESUPRON is a first-in-class, orally-administered uPA inhibitor targeting gastrointestinal and other solid tumors. MESUPRON completed a total of ten Phase I and Phase II clinical studies, and the ongoing development program is intended to better define the molecular markers and patient population for future clinical studies. RedHill plans to initiate a Phase II development program with MESUPRON in 2017, subject to a successful outcome in the ongoing nonclinical studies.
RP101 – First-in-class small molecule for oncology indications (Phase II-stage)
