On September 10, 2026 Prelude Therapeutics Incorporated (Nasdaq: PRLD), a precision oncology company, reported that the U.S. Food and Drug Administration (FDA) cleared the Company to proceed with a Phase 1 study under its Investigational New Drug Application (IND) for PRT13722, an oral KAT6A selective degrader being developed for the treatment of patients with HR+/HER2- breast cancer. The Company expects to begin enrolling patients in the fourth quarter of 2026.

"Recent clinical data validated KAT6 as a targetable mechanism in the treatment of HR+/HER2- breast cancer, including those with actionable mutations," stated Charles Morris, MBChB, MRCP, Chief Medical Officer of Prelude. "Dual KAT6A/B inhibitors, however, demonstrated overlapping toxicities with current backbone therapies may limit the utility in earlier lines of treatment. Our approach of selectively degrading KAT6A has the potential to address this challenge by maximizing the therapeutic window with enhanced efficacy and improved hematological safety, as supported by our preclinical data. We look forward to advancing PRT13722 into the clinic with the ultimate goal of providing a new therapeutic option for patients with HR+/HER2- breast cancer."

The Phase 1 study is a first-in-human, open-label, multicenter study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and antitumor activity of PRT13722 as monotherapy and in combination with endocrine and targeted therapies in adults with locally advanced or metastatic HR-positive, HER2-negative breast cancer.

Highly selective KAT6A oral degrader program

KAT6 is an emerging and clinically validated target in the treatment of ER+ breast cancer. Prelude discovered and is developing first-in-class, highly potent, highly selective and orally bioavailable KAT6A degraders. Prelude believes that selectively degrading KAT6A and sparing KAT6B has the potential for improved efficacy, tolerability and combinability with other agents relative to dual inhibitors of KAT6A/B.

On September 10, 2026 Oncolytics Biotech Inc. (Nasdaq: ONCY) ("Oncolytics" or the "Company"), a clinical-stage immunotherapy company developing pelareorep, reported positive preclinical results evaluating pelareorep in combination with a pan-RAS inhibitor in a RAS-driven colorectal cancer model.

During the initial treatment period, when pelareorep was administered every other day, pelareorep, the pan-RAS inhibitor and the combination each reduced tumor growth compared to the control. The greatest tumor reductions were observed in the RAS inhibitor and combination groups, demonstrating that pelareorep activity was maintained in the presence of RAS inhibition without evidence of antagonism between the two therapies.

Following the transition to less frequent weekly pelareorep dosing, the incremental activity associated with pelareorep became less evident. Together, these findings support further evaluation of optimized pelareorep dosing with RAS inhibitors and the hypothesis that sustained pelareorep activity could potentially deepen or prolong responses to RAS-targeted therapy and thereby delay the emergence of treatment resistance.

Importantly, the findings are consistent with previously published independent research demonstrating that RAS inhibitors do not interfere with the mechanism through which pelareorep selectively infects tumor cells. This biological compatibility provides a rationale for further evaluating whether pelareorep’s tumor-selective and immunologic activity can complement the direct antitumor effects of RAS inhibition and potentially delay the development of resistance.

"These results provide an encouraging first look at combining pelareorep with one of the most important emerging classes of targeted cancer therapies," said Thomas Heineman, MD, PhD, Chief Medical Officer of Oncolytics. "We observed pelareorep activity during the initial intensive dosing period as well as biologic compatibility between pelareorep and RAS inhibition, supporting the continued evaluation of pelareorep/RAS inhibitor combination therapy. Because acquired resistance remains a major limitation of RAS-targeted therapies, we believe these findings provide a compelling rationale to investigate whether sustained pelareorep activity can deepen and prolong responses to RAS inhibition and potentially delay the emergence of resistance. Similarly, pelareorep, because of its unique mechanism of action, may offer a treatment option for patients who become resistant to RAS inhibitors."

Oncolytics plans to expand its preclinical evaluation of pelareorep with RAS inhibitors across additional dosing schedules and RAS-driven tumor models. These studies will be designed to further characterize pelareorep’s contribution to the combination, including its potential impact on the depth and durability of tumor response and the development of resistance to RAS-targeted therapy.

About Pelareorep

Pelareorep is an intravenously delivered, systemically active, investigational immunotherapy with a dual mechanism of action that selectively replicates in tumor cells while activating both innate and adaptive anti-tumor immune responses, including the upregulation of key inflammatory cytokines resulting in the formation of tertiary lymphoid structures and the expansion of tumor-infiltrating lymphocytes. It has been administered to over 1,200 patients, and clinical studies have demonstrated pelareorep’s potential to enhance the activity of checkpoint inhibitors and other anti-cancer therapies across multiple solid tumor types.
