Duality Biotherapeutics, Inc. ( (HK:9606) ) just unveiled an update.

Duality Biotherapeutics will present updated Phase 1/2 data for its core B7-H3 antibody-drug conjugate DB-1311/BNT324 in heavily pretreated metastatic castration-resistant prostate cancer at the 2026 ASCO Genitourinary Cancers Symposium. The study, involving 104 patients across dose optimization and expansion cohorts, showed a confirmed overall response rate of 34.5%, disease control in 87.9% of response-evaluable patients and a median radiographic progression-free survival of 11.3 months, with safety dominated by mostly mild nausea and hematologic events.

Efficacy outcomes appeared consistent in patients with and without prior Lu-177 PSMA therapy, suggesting DB-1311/BNT324 may be viable across different treatment histories, though prior Lu-177 exposure was associated with shorter PSA response duration. The results support the ongoing global Phase 3 trial in taxane-naïve metastatic castration-resistant prostate cancer and reinforce the strategic value of DB-1311/BNT324 for Duality’s oncology franchise, while regulatory cautions highlight that successful development and commercialization are not guaranteed, a key consideration for investors.

The most recent analyst rating on (HK:9606) stock is a Buy with a HK$493.00 price target. To see the full list of analyst forecasts on Duality Biotherapeutics, Inc. stock, see the HK:9606 Stock Forecast page.
