Janux Doses First Patient in Phase 1 Trial of PSMA-Targeted T Cell Engager JANX014
Event summary
- First patient dosed in Phase 1 trial of JANX014, a double-masked PSMA-directed T cell engager, for metastatic castration-resistant prostate cancer (mCRPC).
- JANX014 leverages Janux’s tumor-activated technology platform to selectively activate T cells in the tumor microenvironment.
- Phase 1 study is a first-in-human, open-label, multicenter trial assessing safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy.
- JANX007 remains the lead prostate program, with JANX014 representing an exploratory extension of the strategy.
The big picture
Janux Therapeutics is expanding its portfolio of tumor-activated PSMA therapies, aiming to address multiple treatment settings and mechanisms of immune engagement in prostate cancer. The initiation of the JANX014 Phase 1 trial reflects the company’s strategy to explore complementary approaches while maintaining disciplined execution on its lead program, JANX007. This move aligns with broader industry trends toward developing targeted immunotherapies with enhanced safety and efficacy profiles.
