Study Description
Brief Summary:
This is an open-label, Phase 1/2 study in subjects with advanced or metastatic solid tumors. The study will be divided into 2 parts (Part 1 and 2). Part 1 is a dose-escalation assessment to evaluate the safety and tolerability of the DNA methyltransferase inhibitor azacitidine in combination with the programmed death receptor-1 (PD-1) inhibitor pembrolizumab and the indoleamine 2,3-dioxygenase (IDO-1) inhibitor epacadostat. Once the recommended doses have been determined, subjects with previously treated NSCLC and microsatellite-stable colorectal cancer (CRC) will be enrolled into expansion cohorts in Part 2.

Arms and Interventions

Arm Intervention/treatment
Experimental: Azacitidine + Pembrolizumab + Epacadostat
Part 1 is an open-label 3 + 3 + 3 dose-escalation design based on observing each dose level for a period of 21 days. Part 2 will evaluate the recommended dose determined in Part 1.
Drug: Azacitidine
Five doses of azacitidine will be administered by subcutaneous injection or intravenously (IV) over Days 1 to 7 in Cycles 1 and 2.
Drug: Pembrolizumab
Pembrolizumab will be administered in a 30-minute IV infusion every 3 weeks on Day 1 of each 21-day cycle.
Drug: Epacadostat
Epacadostat tablets will be administered orally twice daily.


Outcome Measures

Primary Outcome Measures :
  1. Part 1: Frequency, duration, and severity of adverse events [ Time Frame: Baseline through 42-49 days after end of treatment, estimated up to 18 months. ]
    A treatment-emergent AE was defined as an event occurring after exposure to at least 1 dose of study drug. A treatment-related AE was defined as an event with a definite, probable, or possible causality to study medication. A serious AE is an event resulting in death, hospitalization, persistent or significant disability/incapacity, or is life threatening, a congenital anomaly/birth defect or requires medical or surgical intervention to prevent 1 of the outcomes above. The intensity of an AE was graded according to the National Cancer Institute common terminology criteria for adverse events (NCI-CTCAE) version 4.03: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (life-threatening).

  2. Part 2: Objective response rate based on modified Response Evaluation Criteria in Solid Tumors version 1.1 (mRECIST v1.1) [ Time Frame: Every 9 weeks for the duration of study participation; estimated to be 18 months. ]
    Defined as the percentage of subjects having a complete response or partial response.


Secondary Outcome Measures :
  1. Part 1: Objective response rate based on mRECIST v1.1 [ Time Frame: Every 9 weeks for the duration of study participation; estimated to be 18 months ]
    Defined as the percentage of subjects having a complete response or partial response.

  2. Part 2: Frequency, duration, and severity of adverse events [ Time Frame: Baseline through 42-49 days after end of treatment, estimated up to 18 months. ]
    A treatment-emergent AE was defined as an event occurring after exposure to at least 1 dose of study drug. A treatment-related AE was defined as an event with a definite, probable, or possible causality to study medication. A serious AE is an event resulting in death, hospitalization, persistent or significant disability/incapacity, or is life threatening, a congenital anomaly/birth defect or requires medical or surgical intervention to prevent 1 of the outcomes above. The intensity of an AE was graded according to the National Cancer Institute common terminology criteria for adverse events (NCI-CTCAE) version 4.03: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe); Grade 4 (life-threatening).

  3. Parts 1 and 2: Percentage of responders determined by immunohistochemistry [ Time Frame: Baseline and Week 5 or Week 6. ]
    Responder is defined as an increase in the number of tumor-infiltrating lymphocytes or the ratio of CD8+ lymphocytes to T regulatory cells infiltrating tumor post-treatment versus pretreatment with pembrolizumab and epacadostat in combination with azacitidine.

  4. Parts 1 and 2: Progression-free survival based on mRECIST v1.1. [ Time Frame: Every 9 weeks for the duration of study participation; estimated to be 18 months. ]
    Defined as the time from date of first dose of study drug until the earliest date of disease progression per mRECIST v1.1, or death due to any cause, if occurring sooner than progression.

  5. Parts 1 and 2: Duration of response based on mRECIST v1.1 [ Time Frame: Every 9 weeks for the duration of study participation; estimated to be 18 months. ]
    Defined as the time from earliest date of disease response until the earliest date of disease progression per mRECIST v1.1, or death due to any cause, if occurring sooner than progression.

    • Stage IIIB or metastatic (Stage IV) NSCLC (according to American Joint Committee on Cancer 7th edition guidelines) who have had disease progression after available therapies for advanced or metastatic disease that are known to confer clinical benefit, been intolerant to treatment, or refused standard treatment.
    • Prior systemic regimens must include previously approved therapies, including a platinum-containing chemotherapy regimen; a tyrosine kinase inhibitor for tumors with driver mutations; and checkpoint inhibitors where approved (except Cohort A1, which must be checkpoint inhibitor-naive).
    • Must have disease progression on a prior PD-1-pathway targeted agent (Cohort A2) or must be PD-1 pathway-targeted treatment naive (Cohort A1).
  • Subjects with recurrent (unresectable) or metastatic CRC:

    • Have histologically confirmed microsatellite stable (MSS) CRC.
    • Stage IV MSS CRC (according to American Joint Committee on Cancer 7th edition guidelines) who have had disease progression after available therapies for advanced or metastatic disease that are known to confer clinical benefit, been intolerant to treatment, or refused standard treatment.
    • Prior systemic regimens must include previously approved therapies, including fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy; an anti-VEGF therapy (if no contraindication); and if KRAS wild type and no contraindication, an anti-epidermal growth factor receptor (EGFR) therapy; and progressed after the last administration of approved therapy.
  • Has baseline tumor biopsy specimen available or willingness to undergo a pretreatment and on-treatment tumor biopsy to obtain the specimen.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Exclusion Criteria:

  • Laboratory parameters not within the protocol-defined range.

  • Known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
  • History or presence of an abnormal ECG that, in the investigator's opinion, is clinically meaningful.
