SINGAPORE, March 14 (Bernama-BUSINESS WIRE) — Prestige BioPharma Limited (950210: KRX), a Singapore-based biopharmaceutical with operations in USA and South Korea, announced positive efficacy and safety results of the Phase 3 study for HD201 (TROIKA), a biosimilar to Herceptin® (trastuzumab), published in JAMA Oncology on March 4, 2022.
The publication highlights comparative efficacy and safety data for patients who received 1-year of treatment with HD201 or referent trastuzumab and completed a median follow-up of 31 months. The study met its primary endpoint (tpCR) and showed equivalent efficacy and comparable safety profile. The tpCR rates were 45% and 48.7% for HD201 and referent trastuzumab, respectively. The difference between the two groups was not significant at −3.8% (95% CI, −12.8% to 5.4%) and fell within the predefined equivalence margins. The results regarding secondary endpoints bpCR, overall response, and response based on mammography, ultrasonography, or clinical tumor evaluations supported the comparable efficacy between HD201 and referent trastuzumab. Similar safety, PK and immunogenicity results were reported for the two treatment arms.
