Brief Summary

The purpose of this study is to determine the safety, tolerability, efficacy, PK and pharmacodynamics of INCAGN01876 when given in combination with retifanlimab. The study will consist of 2 parts: a safety lead-in part (Part 1) followed by a dose expansion part (Part 2).

Detailed Description

The purpose of this study is to determine the safety, tolerability, efficacy, PK and pharmacodynamics of INCAGN01876 when given in combination with retifanlimab in participants with GITR expression in recurrent or metastatic HNSCC who have progressed on or after prior systemic therapy including anti-PD-(L)1 therapy. The study will consist of 2 parts: a safety lead-in part (Part 1) followed by a dose expansion part (Part 2)

  • ECOG performance status of 0 to 1.
  • Measurable disease based on RECIST v1.1.
  • Mandatory pre-treatment and on-treatment tumor biopsies.
  • GITR-positive tumor confirmed by central laboratory before study treatment start.
  • Willingness to avoid pregnancy or fathering children.
Exclusion Criteria
  • Have received chemotherapy, targeted small molecule therapy or curative radiation within 21 days of first dose of study drug; prior mAB for anticancer therapy other within 28 days of first dose of study drug; or investigational study drugs or devices within 28 days or five half-lives prior to enrollment unless approved by medical monitor.
  • Prior treatment with any TNF Super Family agonist therapy.
  • Have not recovered to ≤ Grade 1 from toxic effects of prior therapy.
  • Laboratory and medical history parameters not within the Protocol-defined range before the first administration of study treatment.

Known active HBV or HCV, or Known to be seropositive for HIV.

  • Have an active autoimmune disease that has required systemic treatment in past 2 years (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs).

Primary Outcome Measures
NameTimeMethod
Part 1: Participants With Treatment-Emergent Adverse Events (TEAEs)Screening through 90 days after end of treatment, up to 24 months

A TEAE is any adverse event (AE) either reported for the first time or worsening of a pre-existing event after the first dose of study treatment.

Objective response rate (ORR) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1Assessed every 8 weeks for 12 months, thereafter every 12 weeks up to the end of treatment, up to 24 months.

Defined as the percentage of participants having complete response (CR) or partial response (PR).

Secondary Outcome Measures
NameTimeMethod
Progression-free survival (PFS) based on RECIST v1.1 and mRECISTAssessed every 8 weeks for 12 months, then every 12 weeks, up to 24 months.

Defined as the time from the start of combination therapy until the earliest date of disease progression or death due to any cause.

Part 2: Participants With Treatment-Emergent Adverse Events (TEAEs)Screening through 90 days after end of treatment, up to 24 months

A TEAE is any adverse event (AE) either reported for the first time or worsening of a pre-existing event after the first dose of study treatment.

Duration of response (DOR) based on RECIST v1.1 and mRECISTAssessed every 8 weeks for 12 months, then every 12 weeks, up to 24 months.

Defined as the time from the earliest date of disease response (CR or PR) until earliest date of disease progression or death due to any cause.

Disease control rate (DCR) based on RECIST v1.1 and mRECISTAssessed every 8 weeks for 12 months, then every 12 weeks, up to 24 months.

Defined as the percentage of participants having CR, PR, or stable disease (SD).
