Oncolytics Biotech Inc. (NASDAQ: ONCY) (TSX: ONC) today announced that its partner Adlai Nortye has advanced to the third and final dose escalation cohort of the bridging clinical trial evaluating the safety, tolerability, and preliminary efficacy of pelareorep-paclitaxel combination therapy in Chinese patients with advanced or metastatic breast cancer.
Oncolytics Biotech highlights that the trial’s first two cohorts have completed their dose escalation evaluation periods and indicated pelareorep in combination with paclitaxel was well-tolerated with no new safety signals observed to date.
The dosing regimens for the bridging trial’s second and third cohorts are equivalent to those administered in Oncolytics’ randomized North American breast cancer trials, IND-213 and BRACELET-1, respectively. In IND-213, HR+/HER2- breast cancer patients treated with pelareorep and paclitaxel showed a statistically significant, near doubling of overall survival compared to those treated with paclitaxel alone. BRACELET-1, an ongoing phase 2 study evaluating pelareorep-paclitaxel combination therapy with and without a checkpoint inhibitor, is on track for a top-line data readout in Q4 2022 that will inform the design of a registrational study in the United States. Final results from the Chinese bridging trial are expected to accelerate pelareorep’s development in territories such as China, Hong Kong, and Macau, by allowing Adlai Nortye to include data from IND-213 and BRACELET-1 in future submissions to regulators in these jurisdictions.
“The territories covered by our partnership with Adlai Nortye represent an important component of our business development strategy, as China and the other areas in which Adlai Nortye anticipates commercializing pelareorep are among the largest in the world and growing rapidly,” said Andrew de Guttadauro, President of Oncolytics Biotech U.S. and Global Head of Business Development. “With the bridging trial entering its final cohort less than six months after dosing began, Adlai is making major strides towards satisfying the regulatory criteria needed to accelerate pelareorep’s development in China. The trial also continues to generate positive safety data, which will serve us well as we collaborate with Adlai Nortye to advance pelareorep towards approval in key global markets.”
About Breast Cancer
Breast cancer is the most common cancer in women worldwide, with over two million new cases diagnosed in 2018, representing about 25 percent of all cancers in women. It is the second leading cause of death from cancer in women in America, with an estimated 42,000 deaths in the U.S. in 20201. In China, breast cancer is now estimated to be the largest subtype of cancer among women, with over 416,000 cases and over 117,000 deaths in 20202.
Breast cancer starts when cells in the breast begin to grow out of control. These cells usually form a tumor that can often be seen on an x-ray or felt as a lump. The malignant tumor (cancer) gets worse when the cells grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body.
