Description

Summary

Open-label, Phase II, randomized, controlled study evaluating the efficacy and safety of danvatirsen in combination with pembrolizumab compared with pembrolizumab alone as first-line treatment of patients with recurrent/metastatic (R/M) HNSCC. Two-thirds of patients will be randomized to receive danvatirsen and pembrolizumab and one-third will be randomized to receive pembrolizumab alone.

Official Title

An Open-Label, Phase II, Randomized, Controlled Study of Danvatirsen Plus Pembrolizumab Compared to Pembrolizumab Alone in Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC)

Details

This is a multicenter, open-label, Phase II, randomized, controlled study to determine the efficacy, safety, and other indicators of clinical and biological activity of the combination of danvatirsen and pembrolizumab as first-line treatment for R/M HNSCC.

After providing informed consent, patients will be assessed for eligibility during the screening phase of the study. All patients must be willing and able to provide a formalin fixed paraffin-embedded (FFPE) archival or fresh tumor sample collected during the screening period; a fresh biopsy is preferred if safe and feasible to obtain and consented to by the patient. Following the screening period, eligible patients will be randomized in a 2:1 ratio to danvatirsen + pembrolizumab or pembrolizumab monotherapy, respectively. Patients will receive treatment in 21-day cycles. Patients assigned to the pembrolizumab monotherapy arm will receive treatment until a criterion for discontinuation is met or a maximum of 24 months of treatment. Patients assigned to combination therapy will receive both treatments until a criterion for discontinuation is met or the patient has received a maximum of 24 months of treatment, after which they may remain on danvatirsen monotherapy.

Patients in both treatment arms will have radiologic tumor assessments every 6 weeks (±1 week), regardless of treatment delays, until objective disease progression, initiation of new anticancer treatment, death, withdrawal of consent, or end of study, whichever occurs first.

All patients who discontinue study treatment for any reason will have a safety follow-up visit 30 days (+7 days) after the last dose of study treatment and a follow-up for AEs 90 days (+7 days) after the last dose of pembrolizumab. Patients will be followed for survival at 12 week (±7 days) intervals until death or withdrawal of consent, whichever occurs first. Survival follow-up will continue until at least 15 months after the last patient is randomized in the study.
