What was measured

Dose limiting toxicities (DLT) were defined as one of the AEs in Protocol Section 5.5 that at least possibly related to study treatment. The DLT observation period was 2 cycles of therapy, from the start of Cycle 1 through the start of Cycle 3. Toxicities were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).

Analysis population: Two patients in dose level 1 and one patient in dose level 2 were not evaluable for DLT.

Groups in this outcome

Phase I - Dose Level 1: Pembrolizumab 200mg + Pralatrexate 20mg/m2

Patients receive pralatrexate 20mg/m2 IV over 3-5 minutes on days 1 and 8 and pembrolizumab 200mg IV over 30 minutes on day 1. Courses repeat every 21 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

Phase I - Dose Level 2: Pembrolizumab 200mg + Pralatrexate 30mg/m2

Patients receive pralatrexate 30mg/m2 IV over 3-5 minutes on days 1 and 8 and pembrolizumab 200mg IV over 30 minutes on day 1. Courses repeat every 21 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
