Provisional Patent Filed
A provisional patent has been filed for a novel perioperative strategy using paxalisib to prevent metastatic recurrence in high-risk early-stage TNBC.
-
Strong Preclinical Efficacy
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 Supports Mechanism
Paxalisib completely disrupted (100%) circulating tumor cell clusters in ex vivo patient samples, reinforcing the rationale for preventing metastatic spread.
-
Expansion into Early-Stage TNBC Planned
The company is actively evaluating opportunities to broaden clinical development of paxalisib into earlier-stage TNBC, with details expected in the near term.
Analysis · KZIA · Life Sciences
Compelling preclinical and translational data support a new perioperative use of paxalisib to prevent metastatic recurrence in triple-negative breast cancer. The results showed a 95% reduction in residual disease and local recurrence, a 40% reduction in lung metastatic burden, and complete disruption of circulating tumor cell clusters in patient samples. This significantly expands the potential market for paxalisib beyond advanced disease and strengthens the intellectual property position. The company is actively planning to broaden clinical development into earlier-stage TNBC, which could transform the treatment paradigm and substantially increase the drug's commercial opportunity.
