Study of APVO436 in Patients With AML or MDS

Trial Status: active

The primary objective of the Phase 1 part of the study is to determine the recommended dose of APVO436 administered intravenously to patients with AML or MDS. The primary objective of the Phase 1b part of the study is to evaluate the clinical activity of APVO436 in patients with AML or MDS. APVO436 is being studied in this Phase 1b, open-label, multi-center, two-part dose-escalation/dose expansion study to evaluate the safety, pharmacokinetic/pharmacodynamic (PK/PD), and clinical activity of APVO436 in patients with AML and MDS. The study will be conducted in 2 parts. The first part of this Phase 1B study is an open-label, multiple dose ascending dose escalation phase to determine the recommended dose (RP2D) level of APVO436 for future Phase 2 studies. The goal of the dose expansion phase of the study (Part 2) is to (i) evaluate the safety and tolerability of APVO436 at the RP2D level when it is used as an adjunct to the standard of care and (ii) obtain a preliminary assessment of the anti-leukemia activity of APVO436-containing experimental monotherapy and combination therapy modalities. Study Objectives for Dose Escalation Phase - Primary Objectives are to: 1. Determine the RP2D level of APVO436 administered intravenously (IV) in patients with AML or MDS, and 2. Evaluate the safety and tolerability of APVO436 at the RP2D level when it is used as an adjunct to the standard of care and obtain a preliminary assessment of the anti-leukemia activity of APVO436-containing experimental monotherapy and combination therapy modalities. - Secondary Objectives are to: 1. Define the safety profile and immunogenicity of APVO436; to determine the PK/PD of APVO436; to evaluate the clinical activity of APVO436 in AML and MDS patients. 2. Further evaluate the safety profile and immunogenicity of APVO436 and the PK/PD of APVO436 and the relationship between PK/PD and clinical response. Study Objectives for Dose Expansion Phase - Primary Objective is to evaluate the safety and tolerability of APVO436 at the RP2D level when it is used as an adjunct to the standard of care. - Secondary Objective is to obtain a preliminary assessment of the anti-leukemia activity of APVO436-containing experimental monotherapy and combination therapy modalities.
