Brief Summary

The purpose of this study is to compare the progression-free survival of patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN) treated with VTX-2337 + cisplatin or carboplatin + 5-FU + cetuximab versus patients treated with cisplatin or carboplatin + 5-FU + cetuximab alone (standard-of-care; SOC). Safety and overall survival will also be evaluated.

Detailed Description

This is a randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of VTX 2337 in combination with cisplatin or carboplatin, 5-FU and cetuximab in prolonging the progression-free survival in subjects with recurrent or metastatic squamous cell carcinoma of the head and neck.

OBJECTIVES:

Primary Objective:

To compare the efficacy of VTX 2337 plus SOC to SOC alone in prolonging the PFS of patients with recurrent or metastatic SCCHN using irRECIST evaluated by independent radiology review.

Secondary Objectives:

To compare the following between the two treatment groups:

* Safety of VTX 2337 by adverse events, including clinically significant changes in physical examination, peripheral blood hematology, serum chemistry, urinalysis, and ECG.

* Efficacy of VTX 2337 plus SOC in prolonging the OS of patients with recurrent or metastatic SCCHN.

* Efficacy of VTX-2337 plus SOC on ORR, DOBR, DCR, and DDC by irRECIST and evaluation by independent radiology review.

* Efficacy of VTX-2337 plus SOC on ORR, DOBR, DCR, and DDC by RECIST v1.1 and evaluation by independent radiology review.

* Efficacy of VTX 2337 plus SOC to SOC alone in prolonging the PFS by RECIST v1.1 and evaluation by independent radiology review.

* Efficacy of VTX 2337 plus SOC to SOC alone in prolonging the PFS by irRECIST and evaluation by investigators.

Exploratory Objectives:

* To compare genetic polymorphisms that may impact the response of patients to a TLR8 agonist or to cetuximab between the two treatment groups.

* To compare immune biomarker response to VTX 2337 plus SOC as measured by a multiplexed panel of cytokines, chemokines, and inflammatory markers between the two treatment groups.

* To compare the effect of immune cell subsets within the tumor on response to VTX-2337 and/or clinical outcome, as measured by immunohistochemistry in primary tumor tissue between the two treatment groups.

* To assess the PK of VTX-2337.

OUTLINE:

Subjects will be screened for eligibility (within 14 days) and qualified subjects will be randomized 1:1 to 1 of 2 treatment groups: SOC + VTX 2337 or SOC + placebo.

Tumor assessments will be by CT or MRI starting at Week 12 (± 3 days), then at Week 18 (± 3 days) and every 8 weeks (± 7 days) thereafter. Response will be evaluated by immune-related RECIST criteria (irRECIST) and confirmed by an independent radiologist.

Upon independent confirmation of disease progression, active participation in the study is complete and subjects will undergo the End of Treatment evaluations.

Subjects will be followed for survival until \~12 months after the last subject is randomized.

Primary Outcome Measures
NameTimeMethod
Comparison of Progression Free Survival (PFS) Between Treatment Groups Using irRECIST and Evaluated by Independent Radiology.PFS is the time from randomization until disease progression or death, whichever comes first.

PFS was based on central assessment by a blinded independent radiologist per immune related response evaluation criteria for solid tumors (irRECIST) and was summarized and displayed by treatment arm using Kaplan-Meier methods. Treatments were compared using a stratified log-rank test controlling for randomization stratification factors. The hazard ratio between the 2 treatment arms, as well as the associated one-sided 90% CI and p-value, were presented using a Cox proportional hazards regression model.

Secondary Outcome Measures
NameTimeMethod
Comparison of Overall Survival (OS) Between the 2 Treatment Groups.OS is the time from randomization until death due to any cause or the date last confirmed to be alive.

Estimated using Kaplan-Meier product limit estimates, 1-sided stratified log-rank test, and Cox proportional hazard model; all with 90% 1-sided confidence intervals.

Comparison of Adverse Events (AEs) Between the Two Treatment Groups.AEs were collected from the first dose of study drug given on Cycle 1 Day 1 until 7 days after the dose of study drug or End of Treatment visit, whichever occurred first. Overall mean duration of exposure was 25.3 weeks.

The frequency and severity of adverse events, including any clinically significant changes in physical exam, laboratory values, or other clinical assessment.

Comparison of the Objective Response Rate Between the Two Treatment Groups pFrom the time of randomization until the best response on treatment is documented.

Objective response rate is defined as the percentage of subjects who achieve best overall response of irCR or irPR pr irRECIST and evaluated by independent radiology..
