Announcement
Oncocyte Corp. announced the peer-reviewed publication of positive data related to its proprietary gene expression test, DetermaIO™.
AI Summary
Oncocyte Corp. announced that new, positive data on its proprietary gene expression test, DetermaIO™, has been peer-reviewed and published in Clinical Cancer Research. This study, part of the NeoTRIP clinical trial for triple-negative breast cancer, shows that DetermaIO effectively predicts which patients are likely to benefit from combining immunotherapy with chemotherapy. Patients with a positive DetermaIO result had a significantly higher complete tumor response rate when treated with atezolizumab plus chemotherapy compared to those receiving chemotherapy alone.
The findings highlight that DetermaIO outperforms other biomarkers, making it a useful tool for selecting patients for immune checkpoint inhibitors. These promising results support Oncocyte’s efforts to seek CMS reimbursement and expand access to this valuable diagnostic test in precision oncology.

Oncolytics Biotech® Inc. announced new data from the Phase I/II GOBLET clinical trial in a poster presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting.
AI Summary
Oncolytics Biotech® Inc. has shared encouraging new data from its Phase I/II GOBLET clinical trial at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The company presented a poster explaining how its immunotherapeutic agent, pelareorep, works in pancreatic ductal adenocarcinoma (PDAC). The data show pelareorep starts a cascade of immune responses by expanding anti-reovirus T cells, which then improve the immune activity in the tumor microenvironment. This treatment appears to boost the release of cytokines and chemokines, allowing pre-existing tumor-infiltrating lymphocytes (TILs) in the blood to re-enter the tumor and contribute to tumor shrinkage. By mapping these immune responses, the study enhances understanding of how pelareorep can turn “cold” tumors “hot,” potentially improving combination therapies for PDAC patients.

Oncolytics Biotech® Inc. announced positive clinical results from BRACELET-1, its randomized Phase 2 study evaluating pelareorep in patients with HR+/HER2- advanced or metastatic breast cancer.
AI Summary
Oncolytics Biotech® Inc. announced positive final results from its randomized Phase 2 BRACELET-1 study, which evaluated pelareorep combined with paclitaxel in patients with HR+/HER2- advanced or metastatic breast cancer. The study showed that more than half of the patients receiving the combination therapy were still alive at the end, with the median overall survival (OS) not reached. It is estimated that the OS could be at least 32 months compared to 18 months for patients treated with paclitaxel alone.
The trial also demonstrated a significant benefit in progression-free survival, with the combination arm showing an improvement of almost 6 months over chemotherapy alone. These encouraging results support the potential of pelareorep-based combination therapy to extend survival in these patients. Oncolytics is now moving forward to secure funding for a registration-enabling study based on these positive findings.
