SUZHOU, China, March 24, 2025 /PRNewswire/ -- CStone Pharmaceuticals ('CStone', HKEX: 2616), a biopharmaceutical company dedicated to developing innovative cancer therapies, today announced the submission of a Type II variation application to the European Medicines Agency (EMA) for sugemalimab. The application seeks approval for the treatment of patients with unresectable stage III non-small cell lung cancer (NSCLC) who have not progressed following concurrent or sequential platinum-based chemoradiotherapy (CRT). This marks CStone's second regulatory submission for sugemalimab to the EMA, following its initial approval in Europe for metastatic squamous and non-squamous NSCLC in 2024.

The drug's dual utility in stage III and IV NSCLC could solidify its role as a cornerstone immunotherapy in lung cancer.

CS5001 is so far the first anti-ROR1 ADC known to show clinical anti-tumor activity in both solid tumors and lymphomas. The data presented at ASH highlighted the latest safety and efficacy of CS5001 as a monotherapy for patients with advanced lymphomas. CS5001 is well tolerated in heavily pre-treated patients with advanced B-cell lymphoma. No dose-limiting toxicity (DLT) has been reported up to dose level 10 (DL10). Encouraging anti-tumor activity with high objective response rate (ORR) was observed regardless of ROR1 expression levels, starting from the effective dose, in advanced Hodgkin lymphomas (HLs) (ORR=60.0%) and non-Hodgkin lymphomas (NHLs) (ORR=56.3%). At the preliminary recommended Phase 2 dose (RP2D) of DL8 (125 μg/kg), a notably higher ORR of 76.9% was observed in advanced B-cell lymphoma, including 3 evaluable HL cases with complete or partial response, and an ORR of 70% in NHL. The global multicenter Phase 1 trials of CS5001 are currently in progress in the USA, Australia, and China. Dose escalation has been completed with ongoing backfilling of patients for selective DLs. A Phase 1b dose-expansion study across multiple tumor types with registration potential is expected to be initiated soon.
