-- CT-011 Meets Primary Endpoint of Progression-Free Survival --
-- Achieved Statistically Significant Results in Secondary Endpoint of Overall Survival --
JERUSALEM--(BUSINESS WIRE)-- Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) and CureTech, a portfolio company of Teva and Clal Biotechnology Industries announced today preliminary topline results for CT-011, an investigational anti-PD-1 monoclonal antibody. CT-011 met the primary endpoint of improved progression-free survival (PFS), in a Phase II clinical trial in patients with Diffuse Large B Cell Lymphoma (DLBCL) following autologous stem cell transplantation. Statistically significant results have also been achieved in the secondary endpoint of Overall Survival (OS).
Preliminary analyses indicate that 70% of the patients treated with CT-011 were progression-free at the end of the follow-up period, as compared to only 47% in the historical control. Furthermore, 84% of the patients treated with CT-011 were alive by the end of the follow-up period, compared to only 62% in the historical control.
"We are very pleased to have achieved this major milestone in the clinical development of CT-011," said Dr. Michael Schickler, CEO of CureTech. "Following the final results, CureTech will be ready to commence Phase III regulatory studies for the high unmet need in this severe indication."
“DLBCL is an aggressive type of non-Hodgkin's Lymphoma (NHL) affecting about 40% of all NHL patients," said Jacob M Rowe MD, Director, Department of Hematology, Shaare Zedek Medical Center in Jerusalem, Israel. “I am very encouraged by the results of this trial and am certain that if these results will be confirmed in future controlled Phase III studies, CT-011, a truly novel anti cancer therapy will improve the lives of many DLBCL patients.”
“The results of this early study are exciting,” said Arnon Nagler, MD, Director of the Division of Hematology, BMT and CBB at the Chaim Sheba Medical Center, Israel and co-International Principal Investigator in the study. “There is a significant unmet medical need for therapies that could benefit these patients and I am pleased that such a promising treatment came out of Israeli science.”
Following the successful completion of CureTech's first Phase I study in 2006, Teva took an equity position in the Company, and upon subsequent investments, Teva now holds approximately 33% of CureTech and has an option to further invest in the Company. This opportunity is one of many initiatives in which Teva has invested in recent years. The success of this significant Phase II study encourages Teva to continue leveraging Israeli science.
“When we expanded our collaboration with CureTech in 2008, we did so with the intention of building on CT-011’s success up to that point, and we are incredibly pleased with the Phase II data announced today,” said Dr. Aharon Schwartz, Head of Teva's Innovative Ventures. “Our collaboration with CureTech is just one of many oncology investments and alliances that we have made over the last several years in an effort to build out our portfolio of specialty products within niche therapeutic areas like oncology.”
Final Phase II results for CT-011 in DLBCL are expected to be available during the third quarter of this year. These data will be presented at future international scientific meetings.
ABOUT THE PHASE II STUDY
Seventy two patients in 30 centers in the US, Asia, South America and Israel, entered the study 1-3 months after ASCT. Patients received up to 3 injections of CT-011 every 6 weeks and were then followed for 13 months without further treatment. The historical comparator for this study was a cohort of 198 patients who had participated in the DHAP arm of the CORAL (ASCO, 2009) study (the historical control). In addition to the clinical endpoints, about 100 biomarkers were also monitored at different time points. The results indicate an increase in the number of specific T cells responsible to the maintenance of long-term immunologic memory. This may explain the long term effect of the treatment shown in the study.
ABOUT CT-011
CT-011 was generated by Drs. Brita Hardy and the late Abraham Novogrodsky at the Tel Aviv University and it belongs to a new class of anticancer therapies attempting to harness the body's immune system against the disease. Cancer cells avoid the body's immune system through a mechanism involving the interaction of PD-1, a "programmed death" receptor with its cognate antigen, PD-L1. PD-1 appears on tumor-reactive lymphocytes and induces apoptosis of these cells. CT-011 blocks PD-1 and revitalizes the body's own immune system. Until recently immunotherapy was an unfulfilled dream shared by many cancer researchers. However, during the last two years the validity of this approach was rekindled by the regulatory approval of two immunotherapeutic agents which showed success in clinical trials for cancer patients. In 2007, the National Cancer Institute (NCI) rated PD-1 as the second most promising potential target among approximately 140 pathways and molecules for cancer immunotherapy.
To date more than 400 patients participate in 7 phase II and Phase I/II studies with CT-011 in different cancer indications such as colon cancer, multiple myeloma, acute leukemia, and pancreatic cancer, in cooperation with leading global researchers. CureTech has also recently announced the submission of a protocol to the US FDA for the conduct of a phase II trial in metastatic melanoma, a severe solid tumor indication with very few treatment options. These trials demonstrate the broad potential of the CT-011 antibody.
