Novelos Therapeutics, Inc. (OTCBB: NVLT), a biopharmaceutical company focused on the development of therapeutics to treat cancer and hepatitis, today announced that the primary endpoint of improvement in overall survival was not met in Novelos’ pivotal Phase 3 trial in advanced non-small cell lung cancer (NSCLC) studying its lead product, NOV-002, in combination with first-line chemotherapy. Detailed trial results are expected to be presented via appropriate scientific venue later this year. This randomized, controlled, open-label Phase 3 trial, conducted under a Special Protocol Assessment (SPA) and Fast Track designation, had enrolled 903 patients with Stage IIIb/IV NSCLC, which includes all histological subtypes. The trial, conducted across approximately 100 clinical sites in 12 countries, evaluated NOV-002 in combination with first-line paclitaxel and carboplatin chemotherapy versus paclitaxel and carboplatin alone. The primary efficacy endpoint of the trial was improvement in overall survival. Enrollment commenced in November 2006, target enrollment was achieved in March 2008, and the 725 event (patient death) was announced in early January 2010. According to the trial’s Statistical Analysis Plan (SAP), a total of 725 events were required to detect a 25% improvement (12.5 months versus 10 months) in overall median survival (hazard ratio of 0.8) with 85% power and a two-sided significance level of 0.05. No interim analysis was performed. “We are very disappointed that our pivotal Phase 3 lung cancer trial did not meet the primary survival endpoint,” said Harry Palmin, President and CEO of Novelos. “We were hopeful of a positive outcome based on our statistical model simulations and stated assumptions. In retrospect, it appears our simulations were inaccurate due to trial data deviating from our statistical model, the impact of censoring patterns, and control arm survival exceeding our expectations based on historical precedents. We will conduct a thorough analysis of all the data, and expect to present detailed Phase 3 lung cancer trial results later this year. Meanwhile, we are scheduled to present new NOV-002 preclinical data at the AACR Annual Meeting in April 2010, and we are on track for results from a NOV-002 Phase 2 breast cancer trial in 3Q 2010. We are also on track to initiate a Phase 2 hepatitis C trial shortly, with our second compound NOV-205.”
About NSCLCNSCLC accounts for about 87% of lung cancer, which is the leading cause of cancer death in the U.S. According to the American Cancer Society, approximately 215,000 people were expected to be diagnosed with lung cancer in 2008 in the U.S., with approximately 162,000 deaths. Approximately 1,500,000 new cases of lung cancer were expected worldwide in 2007 and approximately 1,350,000 deaths were projected from lung cancer in 2007. Only about 16% of NSCLC patients are diagnosed early enough to be eligible for surgery. Platinum-based chemotherapy regimens are standard first-line treatment for advanced NSCLC patients. During treatment, patients are subject to serious chemotherapy-induced adverse effects. According to results of 12 Phase 3 clinical trials published from 2001-2008, the one-year survival rate for patients receiving paclitaxel and carboplatin first-line therapy was on average only about 40%, the weighted average for median survival was 9.7 months and the objective tumor response (defined as greater than 30% tumor shrinkage) rate was about 27%. Overall, fewer than 5% of advanced non-small cell lung cancer patients survive five years. Improving on the standard of care in unselected advanced NSCLC remains challenging and elusive. About NOV-002 for NSCLC NOV-002 is a small molecule compound based on a proprietary formulation of oxidized glutathione that acts together with chemotherapy as a chemopotentiator and a chemoprotectant by regulating redox-sensitive cell signaling pathways. The pivotal Phase 3 trial of NOV-002 in 903 advanced NSCLC patients in combination with first-line chemotherapy did not meet the primary endpoint of improvement in overall survival. Previously, three separate Phase 2 trials demonstrated clinical activity and safety of NOV-002 in combination with first-line chemotherapy in NSCLC. NOV-002 has an extensive safety database, and has also demonstrated improved recovery from chemotherapy toxicity in cancer patients. NOV-002 does not appear to be chemotherapy specific or tumor specific.
About Novelos Therapeutics, Inc.Novelos Therapeutics, Inc. is a biopharmaceutical company commercializing oxidized glutathione-based compounds for the treatment of cancer and hepatitis. NOV-002, the lead compound that completed a Phase 3 trial for lung cancer, acts together with chemotherapy as a chemopotentiator and a chemoprotectant. NOV-002 is also in Phase 2 development for early-stage breast cancer and chemotherapy-resistant ovarian cancer. Novelos has a partnership with Mundipharma, an independent associated company of Purdue Pharma, to develop and commercialize NOV-002 in Europe and Asia (excluding China). Novelos’ second compound, NOV-205, acts as a hepatoprotective agent with immunomodulating and anti-inflammatory properties. NOV-205 is in Phase 1b development for chronic hepatitis C non-responders. Both compounds have been partnered with Lee’s Pharm in China. For additional information about Novelos please visit www.novelos.com.
