A Phase 1/2 Randomized, Blinded, Placebo Controlled Study of Ipilimumab in Combination With Epacadostat or Placebo in Subjects With Unresectable or Metastatic Melanoma

March 19, 2019 updated by: Incyte Corporation
The study design includes an open-label, dose escalation phase followed by a blinded, randomized phase, which combines epacadostat (an oral IDO1 inhibitor) with an approved therapy and compares to approved therapy plus placebo in metastatic melanoma patients.

Description

Inclusion Criteria:

  • Male or female subjects, aged 18 years or older with unresectable or metastatic melanoma.
  • A life expectancy of >12 weeks.
  • Laboratory ranges and medical criteria met, as defined within the protocol.
  • Subject may have received more than 1 prior regimen of systematic treatment for unresectable or metastatic melanoma.
  • For Phase 2 period of the study only, Subjects must have archival tumor tissue available and collected with the prior 6 months or accessible disease for pre-treatment, study biopsy.

Exclusion Criteria:

  • Pregnant or nursing women.
  • Current investigational trial participation with another investigational product or subjects who have received any anticancer medications within 21 days prior to screening (6 weeks for mitomycin-C or nitrosoureas.)
  • Subjects receiving monoamine oxidase inhibitors (MAOI)s; subjects who have ever had Serotonin Syndrome after receiving one or more serotonergic drugs.
  • Subjects who have received prior immune checkpoint inhibitors (eg anti-CTLA-4, anti-PD-1, anti- PD-L1 and others) who have had Grade 3 or 4 hepatotoxicity, immune colitis requiring infliximab, endocrine toxicity not controlled by replacement, any other Grade 4 immune adverse events (AEs) or ocular toxicity
  • Subjects with protocol-specified active autoimmune process except vitiligo or thyroiditis.
  • Subjects with concurrent conditions that would jeopardize the safety of the safety of the subject or compliance with the protocol.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Phase 1: Number of patients with adverse events as a measure of Safety and Tolerability.
Time Frame: Baseline and minimally every 3 weeks until discontinuation or death (estimated timeframe to be 29 months from first patient enrolled to last patient discontinued or dead).
Baseline and minimally every 3 weeks until discontinuation or death (estimated timeframe to be 29 months from first patient enrolled to last patient discontinued or dead).
Phase 2: Overall survival.
Time Frame: Measured every 4 weeks until the 50th death occurs, then follow-up is measured every 3 months (estimated timeframe to be 29 months from first patient enrolled to last patient death).
Measured every 4 weeks until the 50th death occurs, then follow-up is measured every 3 months (estimated timeframe to be 29 months from first patient enrolled to last patient death).

Secondary Outcome Measures

Outcome Measure
Time Frame
Preliminary efficacy as assessed by tumor response.
Time Frame: Baseline and every nine weeks (3 cycles) thereafter (estimated timeframe is that each patient will be on study for 11 months).
Baseline and every nine weeks (3 cycles) thereafter (estimated timeframe is that each patient will be on study for 11 months).
Evaluation of progression free survival.
Time Frame: Measured every 4 weeks until the 50th death occurs, then follow-up is measured every 3 months (estimated timeframe is that patients will progress after 11 months).
