Biotechs Zeroing In on Developing Breakthrough Therapeutics for Metastatic Breast Cancer

Palm Beach, FL – June 5, 2023 – News Commentary – The COVID-19 pandemic has had a limited impact on the global breast cancer therapeutics market and reports see substantial growth now that it has receded. The status of breast cancer as one of the most commonly occurring cancers in the world is expected to be a key driving factor for the global market. As more and more patients are diagnosed with breast cancer across the globe, the need for accurate and efficient treatment outcomes for the patient remains unparalleled. Furthermore, the strong trend of continuous R&D amongst key market players engaged in breast cancer therapeutics would lead to the launch of breakthrough therapeutics in the coming years. This trend of introducing new and advanced therapies such as targeted therapies and immunotherapies is expected to strongly surge the growth of the global market in developed as well as emerging regions during the forecast period. A report from Fortune Business Insights projected that the global breast cancer therapeutics market size is projected to reach USD 55.27 billion by 2027, exhibiting a CAGR of 13.1% during the forecast period.  The report said: “One of the most prevalent trends in the global market is the ongoing R&D initiatives for the development and the marketing of efficient drugs for breast cancer treatment. As the number of patients suffering from breast cancer continues to increase across the globe, the importance and the critical need for the development of advanced therapeutics for better outcomes remains unparalleled.  Such trends are expected to significantly boost the global breast cancer therapeutics market growth in the forecast period as the development of new therapeutics is expected to lead to new product launches. This is further set to result in greater sales of breast cancer drugs and the inclusion of new patients in the treatment process, as more types of breast cancers are anticipated to be treated through these new drugs.”  Active biotech and pharma companies in the markets this week include Oncolytics Biotech® Inc. (NASDAQ: ONCY) (TSX: ONC), Gilead Sciences, Inc. (NASDAQ: GILD), Rain Oncology Inc. (NASDAQ: RAIN), CNS Pharmaceuticals, Inc. (NASDAQ: CNSP), Bristol Myers Squibb (NYSE: BMY).


Fortune Business Insights continued: “One of the foremost drivers influencing the growth of the global market is the increased prevalence of breast cancer across the world, which is expected to result in a large patient population demanding accurate and efficient treatment options. Breast cancer is one of the most prevalent forms of cancer worldwide and improved diagnostics are further expected to result in a greater number of patients being diagnosed.  Furthermore, the increasing demand for preventive care and early treatment has led many individuals to undergo cancer screening tests, which would also strongly drive the number of patients demanding treatment in the forecast period. Besides, the increasing patient awareness due to such alarming statistics is anticipated to further drive the market growth. Hence, the rising prevalence of breast cancer is projected to boost market growth in the forecast period.  North America is projected to be the key market in the forecast period (2027). This growth is attributable to the presence of prominent companies in the region, which, in turn, would lead to the launch of new therapeutics in the region. Other reasons include the strong prevalence of breast cancer, the increasing number of breast cancer therapeutics R&D clinical trials, and the increased awareness and adoption of advanced therapeutics.”


Oncolytics Biotech® Inc. (NASDAQ: ONCY) (TSX: ONC) BREAKING NEWS:  Oncolytics Biotech® Announces Updated Randomized Phase 2 Data from BRACELET-1 Metastatic Breast Cancer Trial that Show Pelareorep Driving Robust Increases in Progression-Free Survival and Confirmed Overall Response Rate

  • Pelareorep-paclitaxel combination reduced risk of disease progression by 71% (hazard ratio of 0.29) compared to paclitaxel monotherapy
  • 5% confirmed overall response rate with pelareorep-paclitaxel vs. 13.3% with paclitaxel monotherapy
  • 12-month progression-free survival rate of 32.8% for pelareorep-paclitaxel compared to 0% for paclitaxel monotherapy and 0% for pelareorep-paclitaxel-avelumab
  • Oncolytics’ HR+/HER2- breast cancer program now phase 3-ready and advancing to a registrational study of pelareorep-paclitaxel combination


Oncolytics Biotech® today announced updated results from BRACELET-1, a randomized phase 2 trial in HR+/HER2- metastatic breast cancer, which include data featured in an oral presentation at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, as well as additional new data and analyses.


BRACELET-1 enrolled 48 patients, including 45 that were randomized and well-balanced across three cohorts evaluating: (1) paclitaxel monotherapy; (2) paclitaxel in combination with pelareorep; and (3) paclitaxel plus pelareorep in combination with the anti-PD-L1 checkpoint inhibitor, avelumab (Bavencio®). A three-patient safety run-in was also conducted with patients receiving pelareorep, paclitaxel, and avelumab prior to randomization. All participants enrolled in the trial had previously progressed on at least one hormone-based therapy with a CDK 4/6 inhibitor. No patients in BRACELET-1 received chemotherapy for metastatic disease prior to enrolling in the trial.


Updated data from BRACELET-1 showed a median progression-free survival (mPFS) of 9.5 months in the paclitaxel plus pelareorep cohort vs. 6.3 months in the paclitaxel monotherapy cohort for a hazard ratio of 0.29 as of a March 3, 2023 cut-off date. Confirmed overall response rate (ORR) in these cohorts was 37.5% and 13.3%, respectively. As previously reported, ORR at week-16 (the trial’s primary endpoint) in the pelareorep plus paclitaxel and paclitaxel monotherapy cohorts was 31.3% and 20%, respectively. Overall survival data from the trial continue to mature.


“BRACELET-1’s positive results complement prior phase 2 data showing a statistically significant increase in overall survival when pelareorep was combined with paclitaxel by demonstrating similar robust improvements in PFS and ORR in less heavily pre-treated patients,” said Dr. Matt Coffey, President and Chief Executive Officer. “Given this exciting finding, our next step is to discuss our data with the FDA to investigate incorporating dual PFS and OS endpoints into our breast cancer program’s registrational study. Including a PFS endpoint could substantially reduce the time to a pivotal readout from the registrational trial, thereby accelerating pelareorep’s path to potential approval as we work to address the urgent needs of HR+/HER2- breast cancer patients.”  CONTINUED Read this full press release and more news for ONCY at:
