Provisional Patent Filed for TNBC Strategy
Kazia filed a provisional patent for a perioperative strategy using paxalisib to prevent metastatic recurrence in high-risk early-stage triple-negative breast cancer.
-
Preclinical Data: 95% Reduction in Residual Disease
In a clinically relevant model, adjuvant paxalisib reduced residual disease and local recurrence by 95% (p<0.0001) and lung metastatic burden by 40% (p<0.027).
-
Translational Data: 100% Disruption of CTC Clusters
Ex vivo studies on patient tumor samples showed paxalisib completely disrupted circulating tumor cell clusters, supporting the anti-metastatic rationale.
-
Broader Clinical Development Planned
The company is actively evaluating opportunities to expand paxalisib development into earlier-stage TNBC and expects to provide additional details in the near term.
Analysis · KZIA · Life Sciences
Kazia Therapeutics disclosed new preclinical data supporting a patent filing for a perioperative strategy with paxalisib in high-risk early-stage triple-negative breast cancer. In a clinically relevant model, adjuvant paxalisib reduced residual disease and local recurrence by 95% and lung metastatic burden by 40%. Complementary translational data showed complete disruption of circulating tumor cell clusters in patient samples. These findings expand paxalisib's potential beyond advanced disease and could open a new development path in earlier-stage TNBC, where one-third of patients remain at high risk of metastatic recurrence after standard therapy. The company is actively evaluating broader clinical development and expects to provide details soon.
