Primary Endpoint
The study evaluates treatment-emergent adverse events (TEAEs) over 38 months, including clinically significant lab abnormalities (hematology, serum chemistry, urinalysis, coagulation), ECG changes, and vital sign deviations. Secondary outcomes include objective response rate (ORR) based on RECIST criteria (CR: disappearance of target lesions; PR: ≥50% tumor reduction) assessed until disease progression or new therapy initiation.

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.
