SAN DIEGO, Oct. 10, 2013 /PRNewswire/ -- MEI Pharma, Inc. (Nasdaq: MEIP), an oncology company focused on the clinical development of novel therapies for cancer, today announced that data from the ongoing Phase I clinical trial of its mitochondrial inhibitor drug candidate ME-344 in patients with refractory solid tumors will be presented at the upcoming AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston.
As reported in the abstract of the presentation, eight of the 23 patients evaluable for efficacy (35%) achieved disease control, including one confirmed partial response (PR) in a patient with refractory small cell lung cancer (duration 52+ weeks) and seven patients with prolonged stable disease (SD) ranging from 8 to 40+ weeks. The maximum tolerated dose was established at 10 mg/kg delivered on a weekly schedule. Dose limiting toxicity of Grade 3 neuropathy was observed at 15 mg/kg and 20 mg/kg.
Detailed results from the trial will be presented on Sunday, October 20, 2013 at 12:30 p.m. Eastern time from Exhibit Hall C-D of the Hynes Convention Center. The abstract, entitled "ME-344, a novel mitochondrial oxygenase inhibitor: Results from a first-in-human Phase I study," is now available online at www.aacr.org/home/scientists/meetings--workshops/molecular-targets-and-cancer-therapeutics.aspx.About ME-344 ME-344 is MEI Pharma's next-generation mitochondrial inhibitor drug candidate and an active metabolite of NV-128, the Company's first-generation compound. In April 2013, Ayesha Alvero, M.D., Department of Obstetrics, Gynecology and Reproductive Sciences at Yale University School of Medicine, presented data at the American Association for Cancer Research (AACR) Annual Meeting showing the ability of ME-344 to decrease tumor burden and delay recurrence in a pre-clinical in vivo model of recurrent epithelial ovarian cancer, the most lethal of all gynecologic malignancies. In April 2011, Dr. Alvero also presented data at AACR from a pre-clinical study of NV-128 demonstrating its ability to induce mitochondrial instability, ultimately leading to cell death in otherwise chemotherapy-resistant ovarian cancer stem cells. These results were later published in the August 2011 issue of Molecular Cancer Therapeutics. In additional pre-clinical studies, ME-344 demonstrated superior anti-tumor activity against a broad range of human cancer cell lines compared to NV-128. MEI Pharma owns exclusive worldwide rights to ME-344.
