Study Details

Study Description

Brief Summary

This is a phase Ib study with a safety lead-in (n = 6 per arm) evaluating combinatorial DPV-001 + sequenced PD-1 blockade, with or without GITR agonist, in recurrent or metastatic HNSCC.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This is a phase Ib trial of an autophagosome vaccine (DPV-001) with or without anti-GITR (INCAGN01876), combined with subsequent anti-PD1 (INCMGA00012), in patients with recurrent or metastatic HNSCC. Eligible patients will be registered and assigned to one of two treatment arms. Subjects in Arm 1 will receive combination therapy with DPV-001 with delayed anti-PD-1, and subjects in Arm 2 will receive DPV-001 and anti-GITR with delayed anti-PD-1 (triplet therapy). Mandatory biopsy will occur at week 2. Initial restaging CT and mandatory biopsy will occur at 8 weeks, followed by confirmatory CT at 12 weeks. Subsequent restaging CT will be performed at week 24 and every 12 weeks thereafter. Starting at week 22, dosing of DPV-101 will switch to a q4wk schedule, while the schedule of anti-GITR and anti-PD1 will remain unchanged.

Study Design

Study Type:
Interventional
Anticipated Enrollment :
56 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
The trial will have a run-in safety phase for each of the 2 arms, starting with arm 1 using a standard 3+3 design. If arm 1 is deemed safe, the safety run-in for arm 2 will begin enrollment, using the same 3+3 design. If arm 2 is deemed safe, enrollment will continue to 15 in each arm (total n = 30). Patients enrolling after the safety run-in will be randomly assigned to either arm 1 or arm 2.The trial will have a run-in safety phase for each of the 2 arms, starting with arm 1 using a standard 3+3 design.
