- Study will evaluate pelareorep's ability to synergistically combine with the checkpoint inhibitor therapy avelumab and improve outcomes in metastatic breast cancer
- Study aims to validate T cell clonality as a biomarker of pelareorep response and enable advancement into a phase 3 registrational study
- BRACELET-1 is being conducted under a co-development agreement with Merck KGaA, Darmstadt, Germany and Pfizer
The randomized BRACELET-1 study is designed to support the results of a prior successful phase 2 trial (IND-213) that showed a near doubling of overall survival with pelareorep treatment, by demonstrating pelareorep's ability to induce a robust anti-tumor immune response in an identical patient population (patients with HR+/HER2- mBC). The ability of pelareorep-induced immune responses to enhance anti- PD-L1 therapy will also be evaluated through the inclusion of the paclitaxel-pelareorep-avelumab combination therapy cohort. Importantly, the trial also aims to validate peripheral T cell clonality as a biomarker of pelareorep response in HR+/HER2- mBC, which may aid in future registrational trial study design and patient selection.
For more information about the BRACELET-1 study, refer to http://ClinicalTrials.gov (NCT04215146).
About BRACELET-1
The BRACELET-1(BReast cAnCEr with the Oncolytic Reovirus PeLareorEp in CombinaTion with anti- PD-L1 and Paclitaxel) study is an open-label, phase 2, randomized study in patients with HR+/HER2-, endocrine-refractory metastatic breast cancer being conducted under a co-development agreement with Merck KGaA, Darmstadt, Germany and Pfizer. PrECOG LLC, a leading cancer research network, is managing the study. The study will take place at 20 trial sites and enroll 45 patients randomized into three cohorts. A three patient safety run-in will be conducted with patients receiving pelareorep, paclitaxel, and avelumab prior to randomization. The three cohorts will be treated as follows:
- Cohort 1 (n=15): paclitaxel
- Cohort 2 (n=15): paclitaxel + pelareorep
- Cohort 3 (n=18): paclitaxel + pelareorep + avelumab (Bavencio®)
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. Incidence rates vary widely across the world, from 27 per 100,000 in Middle Africa and Eastern Asia to 85 per 100,000 in Northern America. It is the fifth most common cause of death from cancer in women globally, with an estimated 522,000 deaths.
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) is getting worse when the cells grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body.
About Pelareorep
Pelareorep is a non-pathogenic, proprietary isolate of the unmodified reovirus: a first-in-class intravenously delivered immuno-oncolytic virus for the treatment of solid tumors and hematological malignancies. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype through innate and adaptive immune responses to treat a variety of cancers and has been demonstrated to be able to escape neutralizing antibodies found in patients.
About Oncolytics Biotech Inc.
Oncolytics is a biotechnology company developing pelareorep, an intravenously delivered immuno- oncolytic virus. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype -- turning "cold" tumors "hot" -- through innate and adaptive immune responses to treat a variety of cancers.
Pelareorep has demonstrated synergies with immune checkpoint inhibitors and may also be synergistic with other approved immuno-oncology agents. Oncolytics is currently conducting and planning additional studies in combination with checkpoint inhibitors and targeted therapies in solid and hematological malignancies, as it prepares for a phase 3 registration study in metastatic breast cancer.
