Announcement
Protara Therapeutics, announced positive data from three-month evaluable carcinoma in situ (CIS) patients treated across its ongoing clinical program of TARA-002, the Company's investigational cell-based therapy, in high-risk Non-Muscle Invasive Bladder Cancer (NMIBC), including Bacillus Calmette-Guérin (BCG)-Unresponsive, BCG-Experienced and BCG-Naïve patient populations.
AI Summary
Protara Therapeutics shared positive three‐month data from its NMIBC clinical program with TARA-002, an investigational cell-based therapy aimed at treating high-risk non-muscle invasive bladder cancer. The results focused on carcinoma in situ (CIS) patients, including those who are BCG-Unresponsive, BCG-Experienced, and BCG-Naïve. In patients with CIS only, the complete response (CR) rate was 63%, while the overall CR rate across varying disease stages was 38%. These encouraging findings suggest that TARA-002 could benefit NMIBC patients who currently have limited treatment options. Researchers also noted a favorable safety profile, as no Grade 3 or higher treatment-related adverse events were observed. The study investigators believe that reinduction therapy could further enhance response rates, building on what is known from other immune therapies used for bladder cancer.
