Official title

A Phase 3 Open-label, Randomized Controlled Study to Evaluate the Efficacy and Safety of Petosemtamab Compared With Investigator's Choice Monotherapy Treatment in Previously Treated Patients With Incurable, Metastatic/Recurrent Head and Neck Squamous Cell Carcinoma

Overview

This is a phase 3 open-label, randomized, controlled, multicenter study to compare petosemtamab vs investigator's choice monotherapy in HNSCC patients for the second- and third-line treatment of incurable metastatic/recurrent disease.

Detailed description

This is a phase 3 open-label, randomized, controlled, multicenter study to compare petosemtamab vs investigator's choice monotherapy in HNSCC patients for the second- and third-line treatment of incurable metastatic/recurrent disease. HNSCC patients must have progressive disease (PD) on or after anti-PD-1 therapy and platinum-containing therapy. Patients treated with platinum-containing therapy only in the adjuvant setting, or in the context of multimodal therapy for locally advanced disease, should have PD within 6 months of the last dose of platinum-containing therapy.

  • HNSCC participants progressed on or after anti-PD-1 therapy and platinum-containing therapy.
  • The eligible HNSCC primary tumor locations are oropharynx, oral cavity, hypopharynx, and larynx.
  • Documentation of p16 status (positive or negative) by local laboratory IHC for participants with primary oropharyngeal cancer.

  • Measurable disease as defined by RECIST v1.1 by radiologic methods.
  • ECOG PS of 0 or 1
  • Life expectancy ≥ 12 weeks, as per investigator

  • Known leptomeningeal involvement
  • Any systemic anticancer therapy within 4 weeks prior to randomization.
  • Major surgery within 3 weeks or palliative radiotherapy within 2 weeks prior to randomization.
  • Persistent Grade >1 clinically significant toxicities related to prior antineoplastic therapies
  • History of hypersensitivity reaction to any of the excipients of treatment required for this study.
  • Unstable angina; history of congestive heart failure of Class II-IV New York Heart Association (NYHA) criteria, or serious cardiac arrhythmia requiring treatment or history of myocardial infarction within 6 months of study entry
  • History of prior malignancies with the exception of localized cancer with curative resection (e.g. cervical intraepithelial neoplasia or nonmelanoma skin cancer)
