Kazia Therapeutics to Participate in J.P. Morgan Healthcare Conference Week; Clinical and Translational Update Anticipated Before Month-End

SYDNEY, Jan. 8, 2026 /PRNewswire/ -- Kazia Therapeutics (NASDAQ: KZIA) today announced that its Chief Executive Officer, John Friend, MD, will be in San Francisco next week to participate in meetings during the annual J.P. Morgan Healthcare Conference week (JPM Week).

During the week, Kazia will connect with existing and prospective institutional investors, sell-side analysts, and strategic collaborators, including both established partners and potential new industry counterparties, as part of ongoing investor relations and business development outreach.

"We are entering JPM Week with strong strategic and clinical momentum," said Dr. John Friend, M.D., Chief Executive Officer of Kazia Therapeutics. "Following the successful completion of our recent financing, we are well capitalized to execute across multiple near-term catalysts, including an anticipated triple negative breast cancer clinical and biomarker update before the end of the month. At the same time, renewed industry focus on the PI3K/mTOR pathway—particularly in hormone receptor–positive, HER2-negative breast cancer—underscores the growing relevance of approaches that are designed to be differentiated and patient-friendly, such as paxalisib."

Anticipated Clinical and Program Updates

Kazia expects to provide a clinical and translational update before the end of the month from its ongoing Phase 1b trial evaluating paxalisib in advanced triple-negative breast cancer (TNBC). The update is anticipated to include additional clinical response observations, together with expanded circulating tumor cell (CTC) and CTC cluster biomarker analyses, further evaluating paxalisib's potential impact on metastatic disease biology.

As previously reported, paxalisib treatment in advanced TNBC has been associated with rapid and sustained reductions in CTCs and CTC clusters, biomarkers increasingly linked to metastatic potential and adverse clinical outcomes. Notably, prior observations in the patient demonstrated that temporary interruption of paxalisib dosing was accompanied by a rebound increase in CTC clusters, with subsequent re-initiation again suppressing overall CTC count and cluster formation, supporting a mechanistically distinct and pharmacodynamically consistent contribution beyond that of immunotherapy alone.

The impending update could meaningfully expand the clinical and biological dataset supporting paxalisib in metastatic breast cancer, providing further context around treatment response, biological consistency, and translational relevance, and may further inform the broader development strategy for paxalisib across breast cancer subtypes.

In addition, Kazia plans to provide the first update on its potential first-in-class PD-L1 protein degrader program. This program is designed to leverage a novel and differentiated mechanism of action, reflecting evolving scientific strategies aimed at addressing biological complexity, resistance, and durability challenges in immune-based cancer therapies.
