Azacitidine Combined With Pembrolizumab and Epacadostat in Subjects With Advanced Solid Tumors (ECHO-206)
This is an open-label, Phase 1/2 study in subjects with advanced or metastatic solid tumors. The study has three separate treatment groups where separate epigenetic agents are evaluated with an immunotherapy combination. Treatment Group A will evaluate 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; Treatment Group B will evaluate the bromodomain and extra-terminal (BET) inhibitor INCB057643 with pembrolizumab and epacadostat; and Treatment Group C will evaluate the lysine-specific demethylase 1A (LSD1) inhibitor INCB059872 with pembrolizumab and epacadostat. 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 combination therapies. Once the recommended doses have been determined, subjects with previously treated NSCLC, microsatellite-stable colorectal cancer (CRC), head and neck squamous cell carcinoma, urothelial carcinoma, and melanoma will be enrolled into expansion cohorts in Part 2.

- Willingness to undergo a pretreatment and on-treatment tumor biopsy to obtain tumor tissue.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Part 1: Subjects with histologically or cytologically confirmed advanced or metastatic solid tumors that have failed prior standard therapy (disease progression; subject refusal or intolerance is also allowable).
- Part 2:
*Note: Subjects must have failed available therapies that are known to confer clinical benefit as indicated below, unless they are ineligible, intolerant, or refused standard treatment.
- Subjects with histologically or cytologically confirmed NSCLC:
- Metastatic (Stage IV) or recurrent 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.
- Must have disease progression on a prior PD-1-pathway targeted agent.
- 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 negative for KRAS, NRAS, and BRAF mutations and no contraindication, an anti-epidermal growth factor receptor(EGFR) therapy; and progressed after the last administration of approved therapy.
- Subjects with HNSCC:
- Histologically confirmed squamous cell carcinoma of the oral cavity, oropharynx,hypopharynx, or larynx.
- Carcinomas of the nasopharynx, salivary gland, or nonsquamous cell histology are excluded.
- Must have received prior treatment with a platinum-based therapy
- Must have had documented disease progression while on a prior PD-1 pathway-targeted agent.
- Subjects with melanoma:
- Histologically or cytologically confirmed melanoma.
- Unresectable Stage III or Stage IV melanoma, as per American Joint Committee on Cancer staging system not amenable to local therapy.
- Subjects with urothelial carcinoma:
- Histologically or cytologically confirmed urothelial carcinoma of the renal pelvis, ureter, urinary bladder, or urethra that is transitional cell or mixed transitional/nontransitional (predominantly transitional) cell type.
- Stage IV locally advanced or metastatic urothelial carcinoma (according to American Joint Committee on Cancer 7th edition guidelines) with documented disease progression while on a PD-1 pathway targeted therapy.
