An Open-Label, Dose-Escalation/Dose-Expansion Safety Study of INCB059872 in Subjects With Advanced Malignancies
Results Available
Clinical Study Purpose
This is an open-label, dose-escalation/dose-expansion study of INCB059872 in subjects with advanced malignancies. The study will be conducted in 4 parts. Part 1 (mono therapy dose escalation) will determine the recommended dose(s) of INCB059872 for dose expansion, based on maximum tolerated dose and/or a tolerated pharmacologically active dose. Part 2 (dose expansion) will further determine the safety, tolerability, efficacy, PK, and PD of the selected monotherapy dose(s) in AML/MDS, SCLC, myelofibrosis, Ewing sarcoma, and poorly differentiated neuroendocrine tumors. Part 3 will determine the recommended dose(s) of INCB059872 in combination with azacitadine and all-trans retinoic acid in AML and in combination with nivolumab in SCLC. Part 4 will further determine the safety, tolerability, efficacy, PK, and PD of the selected combination dose(s) in Part 3.

Key Inclusion and Exclusion Criteria
Inclusion Criteria
- Male or female subjects, age 18 years or older.
- Presence of measurable disease that has been confirmed by histology or cytology.
Exclusion Criteria
- Receipt of anticancer medications, anticancer therapies, or investigational drugs within the defined interval before the first administration of study drug.
- Any unresolved toxicity ≥ Grade 2 from previous anticancer therapy except for stable chronic toxicities (≤ Grade 2) not expected to resolve.
Protocol Summary
Safety and tolerability of INCB059872 in monotherapy and in combination with other therapies as measured by the frequency, duration, and severity of adverse events (AEs) in participants, and determine recommended dose(s) for further study
Timeframe: AEs assessed from screening through 30 days after end of treatment, up to 6 months
Tumor response rates in subjects with measurable disease
Timeframe: Tumor response at protocol-defined intervals from baseline through end of treatment, up to approximately 6 months
Maximum observed plasma concentration (Cmax) of INCB059872
Timeframe: 0.5, 1, 2, 4, 6 hours postdose on Days 1 and 15 in treatment Cycle 1 and for food effect in Cycle 2, up to approximately 1 month
Area under the single-dose plasma concentration-time curve (AUC0-t) of INCB059872
Timeframe: 0.5, 1, 2, 4, 6 hours postdose on Days 1 and 15 in treatment Cycle 1 and for food effect in Cycle 2, up to approximately 1 month
