Official Title: An Open-Label Phase 1b Study of the Safety, Tolerability, and Preliminary Antitumor Activity of INCB059872 in Participants With Relapsed or Refractory Ewing Sarcoma
Actual Study Start Date : June 27, 2018
Actual Primary Completion Date : June 25, 2020
Actual Study Completion Date : June 25, 2020

Arm Intervention/treatment
Experimental: INCB059872
Drug: INCB059872
Part 1: Initial cohort of INCB059872 administered every other day (QOD) at the protocol-defined starting dose, with subsequent cohort dose escalation based on protocol-defined criteria. Part 2: Expansion with the recommended dose from Part 1.

Primary Outcome Measures :
  1. Number of adverse events [ Time Frame: Screening through 30 days after last dose of study treatment, up to approximately 6 months. ]
    Defined as any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of a drug in humans, whether or not considered drug-related.

Secondary Outcome Measures :
  1. Objective response rate [ Time Frame: Up to approximately 6 months. ]
    Defined as the percentage of participants who have a complete response or partial response as determined by investigator assessment of response per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

  2. Cmax of INCB059872 [ Time Frame: Up to approximately 2 weeks. ]
    Defined as maximum observed plasma concentration.

  3. tmax of INCB059872 [ Time Frame: Up to approximately 2 weeks. ]
    Defined as time to maximum concentration.

  4. t½ of INCB059872 [ Time Frame: Up to approximately 2 weeks. ]
    Defined as apparent terminal-phase disposition half-life.

  5. Cl/F of INCB059872 [ Time Frame: Up to approximately 2 weeks. ]
    Defined as apparent oral dose clearance.

Layout table for eligibility information
Ages Eligible for Study:   12 Years and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically or cytologically confirmed diagnosis of Ewing sarcoma and have progressed on or after standard therapies.
  • Must not be a candidate for potentially curative therapy or standard-of-care approved therapy.
  • Measurable disease by computed tomography or magnetic resonance imaging based on RECIST 1.1 as determined by site radiology.
  • Eastern Cooperative Oncology Group performance status 0 to 2.
  • Willingness to avoid pregnancy or fathering children.

Exclusion Criteria:

  • Receipt of anticancer medications, anticancer therapies, or investigational drugs within protocol-defined intervals before the first administration of study drug.
  • Must have recovered (≤ Grade 2 or at pretreatment baseline) from adverse events (AEs) from previously administered therapies except for stable chronic toxicities (≤ Grade 2) not expected to resolve.
  • Untreated brain or central nervous system (CNS) metastases or brain/CNS metastases that have progressed.
  • Prior radiotherapy within 2 weeks of study treatment. A 1-week washout period is permitted for palliative radiation to non-CNS disease with medical monitor approval.
  • Laboratory values outside the protocol-defined range at screening.
  • History or evidence of bleeding disorder or active clinically significant bleeding requiring medical intervention.
