What was measured

Based on investigator review of radiographic images according to Response Evaluation Criteria In Solid Tumors for immune-based therapeutics (iRECIST). Objective response rate according to iRECIST was defined as the percentage of participants with complete response according to iRECIST or partial response according to iRECIST for target lesions and assessed by CT/MRI.

Analysis population: Patients who were exposed to nanrilkefusp alfa for at least 1 cycle and with at least 1 evaluable tumor assessment per iRECIST after nanrilkefusp alfa treatment start were analyzed. In the trial protocol and SAP it was pre-specified that the arms in individual trial parts will be analyzed combined (A, A1, B, D, and B1).

Groups in this outcome

Part A (Nanrilkefusp Alfa Monotherapy)

Nanrilkefusp alfa was administered on day 1 (±1 day), day 2, day 8, and day 9 of the 21-day treatment cycle as a once-daily dose.

Part A1 (Nanrilkefusp Alfa Divided Dosing, Monotherapy)

Nanrilkefusp alfa was administered on day 1 (±1 day), day 2, day 8, and day 9 of the 21-day treatment cycle twice a day as 2 divided doses (50%:50%) with the second dose on each treatment day administered 8 hours (±15 min) after the first dose.

Part B (Nanrilkefusp Alfa Combined With Pembrolizumab)

Nanrilkefusp alfa was administered on day 1 (±1 day), day 2, day 8, and day 9 of the 21-day treatment cycle as a once-daily dose. Pembrolizumab 200 mg was administered intravenously on day 1 of the 21-day treatment cycle.

Part D (Nanrilkefusp Alfa Monotherapy, Expansion at the RP2D Identified in Part A)

Nanrilkefusp alfa was administered on day 1 (±1 day), day 2, day 8, and day 9 of the 21-day treatment cycle as a once-daily dose.

Part B1 (Nanrilkefusp Alfa Twice Daily With Pembrolizumab, Expansion at RP2D Identified in Part A)

Nanrilkefusp alfa was administered on day 1 (±1 day), day 2, day 8, and day 9 of the 21-day treatment cycle twice a day as 2 divided doses (50%:50%) with the second dose on each treatment day administered 8 hours (±15 min) after the first dose. Pembrolizumab 200 mg was administered intravenously on day 1 of the 21-day treatment cycle.
