Combination Therapy With NC-6004 and Pembrolizumab in Head and Neck Cancer Subjects Who Have Failed Platinum Regimen

Overview

In Phase IIa, dose-escalation study to determine the optimum tolerated dose and a recommended Phase IIb (RPIIb) dose in combination with pembrolizumab in subjects with recurrent or metastatic squamous cell carcinoma of the head and neck who have failed platinum or a platinum containing regimen. In Phase IIb, randomized control study between NC-6004 in combination with pembrolizumab versus pembrolizumab alone in the same subject population as Part 1 at the RPIIb dose identified in PIIa.

Full Title of Study: “Phase IIa/IIb Clinical Trial of NC-6004 in Combination With Pembrolizumab in Subjects With Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck Who Have Failed Platinum or a Platinum-containing Regimen”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: April 30, 2021

Interventions

  • Drug: NC-6004
    • NC-6004 should be administered to subjects once every 3 weeks. On Day 1 of each treatment cycle NC-6004 will be administered first followed by pembrolizumab.
  • Drug: Pembrolizumab
    • The recommended dose of pembrolizumab is 200 mg administered as an IV infusion over 30 minutes every 3 weeks.

Arms, Groups and Cohorts

  • Experimental: NC-6004 +pembrolizumab
    • NC-6004 should be administered to subjects once every 3 weeks. On Day 1 of each treatment cycle NC-6004 will be administered first followed by pembrolizumab. In phase IIa portion, NC-6004 dose goes up from 90 mg/m2 up to 135 mg/m2. In phase IIb portion, the dose should be the determined RPII dose in phase IIa portion.
  • Active Comparator: Pembrolizumab
    • The recommended dose of pembrolizumab is 200 mg administered as an IV infusion over 30 minutes every 3 weeks.

  • Compare overall response (complete response and partial response) rate between NC-6004 +pembrolizumab and pembrolizumab alone
    • Time Frame: 1 year
    • In PIIb portion, to ORR between NC-6004 plus pembrolizumab and pembrolizumab alone

    • Time Frame: 1 year
    • In PIIb portion, to compare DOR between NC-6004 plus pembrolizumab and pembrolizumab alone
  • Compare time to response between NC-6004 +pembrolizumab and pembrolizumab alone
    • Time Frame: 1 year
    • In PIIb portion, to compare TTR between NC-6004 plus pembrolizumab and pembrolizumab alone
  • Safety and tolerability as measured by severity of Adverse Events (AEs)
    • Time Frame: 1 year
    • The safety endpoints for this study are the incidence and severity of AEs in accordance with the NCI CTCAE and the occurrence of SAEs and treatment discontinuations due to AEs
  • Assess the Maximum Plasma Concentration (Cmax) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of the Maximum Plasma Concentration (Cmax)
  • Assess the Time to Maximum Concentration (Tmax) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of Time to Maximum Concentration (Tmax)
  • Assess the Area Under the Concentration (AUC) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of Area Under the Concentration (AUC)
  • Assess the Half-life(T½) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of Half-life(T½)
  • Assess the Clearance (CL) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of Clearance (CL)
  • Assess the Volume of Distribution (V) of NC-6004 in combination with pembrolizumab
    • Time Frame: 1 year
    • Assess PK parameters of Volume of Distribution (V)
