Three Schedules of CUE-101 Administered Before Surgery or Definitive Chemoradiation Therapy in HLA-A*0201 Positive Patients With Locally Advanced, HPV16-Positive Oropharyngeal Squamous-Cell Carcinoma

NCT04852328

Description:

This is a phase 2 trial to assess the safety and tolerability of three schedules of CUE-101 administered in the neoadjuvant phase before standard of care (SOC) therapy to treatment naïve, HLA-A*0201 positive patients with newly diagnosed, locally advanced HPV16+ oropharyngeal squamous-cell carcinoma (OPSCC). This is an exploratory trial of a limited sample size to confirm safety and to assess for pharmacodynamic signals of efficacy in each of three schedules of CUE-101. Safety assessments will be performed at baseline and after CUE-101 administration. To assess for efficacy, peripheral blood and tumor samples will be collected at baseline and after CUE-101 administration. Following CUE-101, patients will proceed with SOC therapy, as prescribed by the treating physician.

Primary Outcome Measures

Measure:Number of treatment-related adverse events
Time Frame:From start of treatment through 12 months after the completion of standard of care treatment (estimated to be 15 months)
Safety Issue:
Description:-Defined as >7 days of treatment-related delay from the planned date of surgery or initiation of definitive-chemoradiation therapy.

Secondary Outcome Measures

Measure:Pathological tumor response
Time Frame:At the time of surgery or biopsy (Day 1 - approximately 7-14 days after start of CUE-101 treatment)
Safety Issue:
Description:Defined as rates of major and complete pathological response A major pathologic response (mPR) will be defined as ≤ 10% residual viable tumor within the tumor sample collected after administration of CUE-101. A complete pathologic response (cPR) will be defined as no invasive cancer in the tumor sample collected. For surgical patients, the tumor sample will include the primary tumor specimen and all sampled regional lymph nodes at the time of resection. For def-chemoradiation therapy patients, the tumor sample will comprise the biopsy(s) submitted. Pathologic tumor response will be stratified based on if the patients underwent surgery or post-CUE-101 biopsy only.

Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Disappearance of all non-target lesions and normalization of tumor marker level. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
