- Clinical Trial Progress: Kazia Therapeutics reports significant clinical responses in its ongoing Phase 1b trial for late-stage metastatic triple-negative breast cancer, with three patients showing meaningful responses, including two partial responses and one complete metabolic response, indicating the potential of paxalisib.
- Funding Support: In December 2025, Kazia raised approximately $46.5 million to support the continued clinical development of paxalisib, with plans to enroll twelve TNBC patients by the end of 2026, further advancing its research efforts.
- Safety and Tolerability: Paxalisib, when combined with pembrolizumab and chemotherapy at a daily dose of 30 mg, has demonstrated a favorable safety profile, with only one case of Grade 1 hyperglycemia observed, requiring no intervention, suggesting a relatively low risk for this treatment regimen.
- Future Plans: Kazia anticipates activating two additional clinical sites by April 2026, with plans for two more by mid-2026, aiming to accelerate patient recruitment and target topline data readout in early 2027, showcasing its strategic positioning in breast cancer treatment.

About KZIA
Kazia Therapeutics Limited is an Australia-based pharmaceutical drug development company. The Company operates in the pharmaceutical research and development business. The Company’s lead program is paxalisib, an investigational brain-penetrant inhibitor of the PI3K / Akt / mTOR pathway, which is being developed to treat multiple forms of brain cancer. It is also developing EVT801, a small-molecule inhibitor of VEGFR3, which is critical to the development of new blood vessels and lymphatic vessels in a growing tumor, as well as to the metastasis of tumors to distant sites in the body. It designed paxalisib to inhibit PI3K, a critical control mechanism in growth and cell division, which is activated in many forms of cancer. The Company’s drug candidates are designed to treat diseases, such as brain cancer, renal cancer, and liver cancer.
