Summary
Brief summary (as posted)
This is a safety, pharmacokinetic and pharmacodynamic study designed to estimate the maximum tolerated dose (MTD), and determine the Recommended Phase 2 Dose (RP2D) of PF-05082566, a 4-1BB agonist monoclonal antibody (mAb), in combination with MK-3475, a PD-1 inhibitor in patients with solid tumors.

- description
- Severity of adverse events (AEs) was graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. For the purpose of dose escalation, any of the following AEs occurring during the DLT observation period that were attributable to one or both study drugs were classified as DLTs. 1) Hematologic: Grade 4 neutropenia; Febrile neutropenia, defined as absolute neutrophil count (ANC) \<1000/mm3 with a single temperature of \>38.3C(101F) or a sustained temperature of 38C (100.4F) for more than 1 hour; Grade\>=3 neutropenic infection; Grade\>=3 thrombocytopenia with bleeding; Grade 4 thrombocytopenia. 2) Non hematologic: Grade\>=3 toxicities (non-laboratory); Grade\>=3 nausea, vomiting or diarrhea despite maximal medical therapy; Grade 4 aspartate aminotransferase (AST) and alanine aminotransferase (ALT). 3) Other (non-AST/ALT) non-hematologic Grade\>=3 laboratory value. 4) Inability to complete 2 infusions of MK-3475 and PF-05082566 during the DLT observation period.
