- The open-label, dose-escalation, pharmacokinetic (PK) and pharmacodynamic (PD) Phase I study with YELIVA™ (ABC294640) in patients with advanced solid tumors was supported by grants from the National Cancer Institute (NCI) and the FDA’s Office of Orphan Products Development (OOPD)
- Analysis of the study is ongoing, with top-line results expected early in the fourth quarter of 2015, and a full analysis and final Clinical Study Report (CSR) expected by the end of this year or early 2016
- Preliminary positive results were reported at the AACR-NCI-EORTC Conference on Molecular Targets and Cancer Therapeutics in November 2013
- YELIVA™ (ABC294640) is a proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor targeting multiple oncology, inflammatory and gastrointestinal indications
- A Phase I/II study with YELIVA™ (ABC294640) was recently initiated in the U.S. in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) and is supported by a grant from the NCI
- A second Phase II study is planned to evaluate YELIVA™ as a radioprotectant in cancer patients undergoing therapeutic radiotherapy; a third Phase II study, to be supported by an NCI grant, is planned for the treatment of multiple myeloma
TEL-AVIV, Israel, September 1, 2015 RedHill Biopharma Ltd. (NASDAQ/TASE: RDHL) (“RedHill” or the “Company”), an Israeli biopharmaceutical company primarily focused on late clinical-stage, proprietary, orally-administered, small molecule drugs for inflammatory and gastrointestinal (GI) diseases, including gastrointestinal cancers, today announced that the last patient has completed the final scheduled follow-up visit in the Phase I study evaluating YELIVA™ (ABC294640), the Company's orally-administered first-in-class sphingosine kinase-2 (SK2) selective inhibitor, for the treatment of advanced solid tumors (the ABC-101 study).
The ABC-101 Phase I study was conducted at the Medical University of South Carolina Hollings Cancer Center and was led by Principal Investigators Melanie Thomas, MD, and Carolyn Britten, MD. The open-label, dose-escalation, pharmacokinetic (PK) and pharmacodynamic (PD) first-in-human Phase I study of YELIVA™ (ABC294640) enrolled 22 patients with advanced solid tumors. The patients were continuously treated with the study drug in the absence of disease progression and evaluated for an additional period of up to one year after discontinuing treatment with YELIVA™ (ABC294640). The primary objectives of the study were to identify the maximum tolerated dose (MTD) and the dose limiting toxicities (DLTs) and to evaluate the safety of YELIVA™ (ABC294640). The secondary objectives of the study were to determine the pharmacokinetic (PK) and pharmacodynamic (PD) properties of YELIVA™ (ABC294640) and to assess its antitumor activity.
The study was supported by grants from the National Cancer Institute (NCI) and the FDA’s Office of Orphan Products Development (OOPD). Preliminary positive data from the Phase I study was presented by Apogee Biotechnology Corporation at the November 2013 Molecular Targets and Cancer Therapeutics meeting.
The analysis of the study is currently ongoing and top-line results are expected to be announced early in the fourth quarter of 2015. A full analysis and the final Clinical Study Report (CSR) are expected by the end of the year or early 2016.
YELIVA™ (ABC294640) is a proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor, with anti-cancer and anti-inflammatory activities, targeting multiple oncology, inflammatory and GI indications. SK2 is an innovative molecular target for anti-cancer therapy because of its critical role in catalyzing the formation of the lipid-signaling molecule sphingosine 1-phosphate (S1P), which is known to regulate cell proliferation and activation of inflammatory pathways. By inhibiting SK2, YELIVA™ (ABC294640) could potentially be effective in treating multiple oncology, inflammatory and gastrointestinal indications.
Reza Fathi, Ph.D., RedHill's Senior VP Research & Development said: “The completion of the final follow-up visit by the last patient in the Phase I study of YELIVA™ (ABC294640) is an important milestone for RedHill, and we look forward to completing the analysis of the study, which includes analysis of plasma S1P levels as a potential new pharmacodynamic biomarker for anti-cancer activity of a sphingolipid targeted drug.”
RedHill recently initiated a Phase I/II clinical study in the U.S. evaluating YELIVA™ (ABC294640) in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL), primarily patients with HIV-related DLBCL, supported by a grant from the NCI Small Business Technology Transfer (STTR) program. Additional Phase II clinical studies are planned, including a multiple myeloma study to be conducted at Duke University and supported by the NCI, and a radioprotection study to evaluate potential prevention of mucositis in cancer patients undergoing therapeutic radiotherapy. Numerous successful pre-clinical studies were conducted with YELIVA™ (ABC294640) in GI, inflammation, radioprotection and oncology models.
The studies with YELIVA™ (ABC294640) are registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies.
About YELIVA™ (ABC294640):
YELIVA™ (ABC294640) is a first-in-class, proprietary sphingosine kinase-2 (SK2) selective inhibitor, administered orally, with anti-cancer and anti-inflammatory activities, targeting multiple potential oncology, inflammatory and gastrointestinal indications. By inhibiting the SK2 enzyme, YELIVA™ (ABC294640) blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid that promotes cancer growth and pathological inflammation. YELIVA™ (ABC294640) was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful pre-clinical studies in oncology, inflammation, GI, and radioprotection models, as well as the ABC-101 Phase I clinical study in cancer patients with advanced solid tumors. A Phase I/II clinical study evaluating YELIVA™ (ABC294640) in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) has been initiated in the U.S. The development of YELIVA™ (ABC294640) was funded to date primarily by grants and contracts from U.S. federal and state government agencies.
