– Phase 1 clinical study of PSMA-TRACTr (JANX007) expected to initiate in 2H 2022 –
Janux Therapeutics, Inc. (Nasdaq: JANX) (Janux), a biopharmaceutical company developing a broad pipeline of novel immunotherapies by applying its proprietary technology to its Tumor Activated T Cell Engager (TRACTr) and Tumor Activated Immunomodulator (TRACIr) platforms, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Company’s investigational new drug (IND) application for its lead product candidate, JANX007, a PSMA-TRACTr in development for the treatment of metastatic castration-resistant prostate cancer (mCRPC). JANX007 is the Company’s lead novel T cell engager (TCE) therapeutic from its TRACTr platform. Janux plans to initiate a Phase 1 clinical trial for JANX007 in the second half of 2022.
“We are proud to announce today the clearance of Janux’s first IND – a critical milestone for our TRACTr platform and for the Company as we advance a broad pipeline of next generation immunotherapies to address unmet needs and improve the treatment of cancer,” said David Campbell, Ph.D., President and CEO of Janux. “JANX007 is uniquely designed to overcome the clinical limitations of existing TCE approaches, potentially providing mCRPC patients a safer therapeutic option, while also generating potent anti-tumor activity by enabling the delivery of a higher concentration of active drug. With this IND acceptance, we are on track to advance JANX007 into the clinic in the second half of this year.”
Unlike existing TCE approaches to prostate cancer that have been limited to-date by dose-limiting toxicities, poor pharmacokinetic (PK) profiles and attenuated efficacy, JANX007 is designed as a safer, highly potent anti-tumor approach to mCRPC. In preclinical studies, JANX007 was well tolerated in non-human primates with limited healthy tissue toxicities and cytokine release syndrome and exhibited enhanced safety and PK properties relative to unmasked TCEs. These data along with the superior manufacturability properties of JANX007 support its further development as an attractive mCRPC therapeutic.
About Janux Therapeutics
Janux Therapeutics is an innovative biopharmaceutical company developing next-generation therapeutics based on applying its proprietary technology to its Tumor Activated T Cell Engager (TRACTr) and Tumor Activated Immunomodulator (TRACIr) platforms to better treat patients suffering from cancer. Janux’s initial focus is on developing a novel class of T cell engagers (TCEs), and its lead product candidates are designed to target clinically validated drug targets. While TCE therapeutics have displayed potent anti-tumor activity in hematological cancers, developing TCEs to treat solid tumors have faced challenges due to the limitations of prior TCE technologies, namely (i) overactivation of the immune system leading to cytokine release syndrome, (ii) on-target, healthy tissue toxicities, and (iii) poor pharmacokinetics leading to short half-life. Janux is using its TRACTr platform technology to engineer product candidates designed to overcome these limitations by offering accuracy, stability, activity, modularity, and manufacturability. Janux is developing a broad pipeline with lead TRACTr programs targeting prostate-specific membrane antigen (PSMA), epidermal growth factor receptor (EGFR), and trophoblast cell surface antigen 2 (TROP2).
