About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC)

Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2 (Appendix C)

Age 18 years or above.

WBC ≥2000/uL

Disqualifiers

Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.

Receipt of any investigational anticancer therapy during the last 28 days or 5 half-lives, whichever is shorter, prior to the first dose of study treatment.

Any concurrent chemotherapy, investigational agent, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.

Local treatment of isolated lesions for palliative intent is acceptable (e.g., local surgery or radiotherapy), excluding target lesions, Palliative radiation therapy cannot be administered less than 1 week prior to the first dose of study treatment.
