Drug: INCB086550
Part 1: INCB086550 once or twice daily with dose modifications based on tolerability criteria. Part 2 and Part 3: Recommended doses from Part 1. |
- Number of treatment-emergent adverse events [ Time Frame: Baseline through 90 days after end of treatment, estimated up to 12 months. ]Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.
- Cmax of INCB086550 in fasted and food effect conditions [ Time Frame: Approximately 1 month ]Maximum observed plasma or serum concentration.
- tmax of INCB086550 in fasted and food effect conditions [ Time Frame: Approximately 1 month ]Time to maximum concentration.
- AUC0-tau of INCB086550 in fasted and food effect conditions [ Time Frame: Approximately 1 month ]Area under the plasma or serum concentration-time curve from time = 0 to the end of dosing period at steady state
- AUC 0-t and/or AUC0-∞ of INCB086550 in fasted and food effect conditions [ Time Frame: Approximately 1 month ]Area under the single-dose plasma concentration-time curve from Hour 0 to the last quantifiable measurable plasma concentration, or Area under the single-dose plasma concentration-time curve from Hour 0 to infinity
- t½ of INCB086550 [ Time Frame: Approximately 1 month ]Apparent terminal-phase disposition half-life.
- λz of INCB086550 [ Time Frame: Approximately 1 month ]Apparent terminal-phase disposition rate constant
- CL/F of INCB086550 [ Time Frame: Approximately 1 month ]Apparent oral dose clearance.
- Vz/F of INCB086550 [ Time Frame: Approximately 1 month ]Apparent oral dose volume of distribution.
- Pharmacokinetic/pharmacodynamics association of INCB086550 exposure with expression levels of PD-L1 [ Time Frame: Approximately 1 month ]Evaluation of the ability of INCB086550 to modulate PD-L1 expression levels as assessed by flow cytometry protein analyses.
- Objective response rate [ Time Frame: Every 8 weeks for the duration of study participation; estimated to be 12 months. ]Defined as the percentage of participants having complete response (CR) or partial response (PR) by investigator assessment of radiographic disease assessments per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
- Disease control rate [ Time Frame: Every 8 weeks for the duration of study participation; estimated to be 12 months. ]Defined as the percentage of participants having CR, PR, or stable disease ≥ 12 weeks by investigator assessment of radiographic disease assessments per RECIST v1.1.
- Duration of response [ Time Frame: Every 8 weeks for the duration of study participation; estimated to be 12 months. ]Defined as the time from the first documented evidence of CR or PR until the earliest date of disease progression by investigator assessment per RECIST v1.1 or death due to any cause, if occurring sooner than progression.
- Cmin of INCB086550 in fasted and food effect condiitons [ Time Frame: Approximately 1 month ]Minimum observed plasma or serum concentration of INCB086550

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Histologically confirmed advanced solid tumors with measurable lesions per RECIST v1.1 that are considered nonamenable to surgery or other curative treatments or procedures. Tumor lesions located in a previously irradiated area, or in an area subjected to other loco-regional therapy, are considered measurable per RECIST v1.1 if progression has been demonstrated in the lesion.
- Willingness to undergo a tumor biopsy to obtain tumor tissue,Pretreatment and on-treatment tumor biopsies are required.
- Must have disease progression after treatment with available therapies that are known to confer clinical benefit or who are intolerant to or ineligible for standard treatment. There is no limit to the number of prior treatment regimens.
- Eastern Cooperative Oncology Group performance status score of 0 or 1.
- Life expectancy > 12 weeks.
- Willingness to avoid pregnancy or fathering children.
- Part 2 Expansion Cohort 2-A only: Participants with any type of solid tumor that has a local regulatory approval for an anti-PD-1 therapy. Other tumor types may be enrolled with medical monitor approval. Participants must have had confirmed disease progression on a prior anti-PD-1 monoclonal antibody.
- Part 2 Expansion Cohort 2-B only: Participants with select solid tumors who are immunotherapy-naïve.
- Part 3 MSI-H or dMMR Expansion Cohort only (Enrolled ex-United States only): Participants with any MSI-H or dMMR solid tumor who are immunotherapy-naïve.
Exclusion Criteria:
- Laboratory values not within the Protocol-defined range.
- Clinically significant cardiac disease.
- History or presence of an ECG that, in the investigator's opinion, is clinically meaningful.
- Untreated brain or central nervous system (CNS) metastases or brain or CNS metastases that have progressed. Participants who have previously treated and clinically stable brain or CNS metastases and have not required steroids for at least 7 days before study treatment are eligible.
- Known additional malignancy that is progressing or requires active treatment.
- Has not recovered to ≤ Grade 1 or baseline from toxic effects of prior therapy and/or complications from prior surgical intervention before starting study treatment.
- Treatment with anticancer medications or investigational drugs within protocol-defined intervals before the first administration of study drug.
- Active infection requiring systemic therapy.
- Evidence of hepatitis B virus or hepatitis C virus infection or risk of reactivation.
- Known history of HIV (HIV 1/2 antibodies).
- Known hypersensitivity or severe reaction to any component of study drug or formulation components.
- Prior receipt of an anti-PD-L1 therapy for all participants.
