Key pharmacokinetic parameters (Cmax, AUC0-t, AUC0-inf, t1/2, CL, Vss, Tmax) for Debio 1562 and rituximab were measured across cycles (21-day intervals) up to 37 months. Efficacy endpoints included PFS (time to progression/death), TTR (time to first response), DOR (response duration), and OS (time to death), with PD defined as new lesions, >50% tumor growth, or nodal enlargement >1.5 cm.

| Primary Endpoint |
The MTD was PCA062 3.60 mg/kg every 2 weeks.No patient achieved a complete response. Only 1 patient with stage IV metastatic HNSCC treated at 0.90 mg/kg achieved a confirmed partial response (PR) as best overall response (BOR).
