(Nasdaq: TARA), a clinical-stage company developing transformative therapies for the treatment of cancer and rare diseases, today announced that patient dosing is now underway in its Phase 1b ADVANCED-1EXP expansion trial evaluating TARA-002, the Company’s investigational cell-based therapy, for the treatment of patients with high-grade non-muscle invasive bladder cancer (NMIBC) who have carcinoma in situ (CIS). “Following positive preliminary results from the ADVANCED-1 trial, we are pleased to have dosed the first patients in our ADVANCED-1EXP trial,” said Jathin Bandari, M.D., Chief Medical Officer of Protara Therapeutics. “We believe TARA-002 has the potential to play a meaningful role in the NMIBC treatment landscape, as there continues to be limited treatment options for this highly recurrent disease. We look forward to gaining additional clinical experience with TARA-002 in NMIBC patients with CIS.” ADVANCED-1EXP is a Phase 1b open-label expansion trial, which is evaluating intravesical TARA-002 at the 40KE1 dose in 12 CIS patients, including Bacillus Calmette-Guérin (BCG)-naïve, BCG-unresponsive and BCG-inadequately treated patients. Trial participants will receive six once-weekly intravesical instillations of TARA-002. The primary objective of the trial is to evaluate the safety, tolerability and signs of anti-tumor activity of TARA-002, and the planned primary endpoint is the complete response (CR) rate at three months. In April 2023 at the American Urological Association Annual Meeting, the Company announced positive preliminary results from the Phase 1a dose-escalation component of the ADVANCED-1 clinical trial of TARA-002 for the treatment of patients with high-grade NMIBC. The clinical data indicate that TARA-002 was generally well tolerated and anti-tumor activity was observed, including tumor regression in all three evaluable patients with CIS, including one heavily pre-treated BCG-unresponsive patient who achieved a CR.
