 Accutar Biotech has terminated the clinical trials of AC176, an AR PROTAC therapy, for the treatment of prostate cancer. These decisions came after the termination of a clinical trial of AC682, an ER PROTAC treatment in the phase 1 stage. Homepage of Accutar The clinical trials AC176 is an AR-targeting PROTAC drug candidate discovered by Accutar Biotech. The IND application was cleared by both the China NMPA and the US FDA. The clinical trial (NCT05673109/CTR20223355) was started in China, with the first patient receiving the dose in February 2023. Currently, the study has enrolled eight patients as reported on the clinical trial disclosure website. However, the trial was terminated due to changes in the benefit-risk ratio for the subjects at the end of 2023. No further statements were reported regarding this matter. The phase 1 trial (NCT05241613) in the US has enrolled 28 patients and has been terminated for the same reason as above. The trial stopped enrolling new patients in O...

  Jing Medicine (和径医药) has submitted the IND application for HJ-002-03, an EGFR-PROTAC, intended for patients with non-small cell lung cancer in China.
