Phase 2
Withdrawn
Conditions
Cutaneous Squamous Cell Carcinoma
Interventions
Registration Number
NCT04985825
Lead Sponsor
Pega-One S.A.S.
Brief Summary

This study will evaluate the anti-tumor activity, safety, tolerability, immunogenicity, pharmacokinetics, and pharmacodynamics of imgatuzumab, a monoclonal antibody against epidermal growth factor receptor (EGFR) with enhanced antibody-dependent cellular cytotoxicity (ADCC) in patients with advanced cutaneous squamous cell carcinoma (CSCC). Quality of life of patients treated with imgatuzumab will also be assessed.

Key

Exclusion Criteria
  • Prior systemic treatment for advanced disease with any anti-EGFR agent
  • Active central nervous system metastasis
  • Systemic anti-cancer therapy within five half-lives or two weeks, whichever is shorter, prior to first dose of the study drug
  • Persistent toxicities from previous systemic anti-neoplastic treatments
  • Wide-field radiotherapy within four weeks, or focal radiation for analgesic purpose or for lytic lesions at risk of fracture within two weeks prior to first dose of the study drug, or no recovery from side effects of such intervention
  • Major surgery within four weeks prior to first dose of the study drug, or no recovery from side effects of such intervention
  • Active infection requiring therapy
  • Concomitant use of systemic steroids at dose of >10 mg of prednisone or its equivalent per day
  • Known or suspected allergy/hypersensitivity to the study drug or any component of the study drug, other monoclonal antibodies, premedication medicines
  • Concurrent participation in another investigational therapeutic clinical trial
  • Pregnant or breast-feeding females
  • Mental or medical conditions that prevent the patient from giving informed consent or participating in the trial
  • Other severe acute or chronic medical or psychiatric conditions or laboratory abnormality that may increase the risk associated with the study participation or the study drug administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for enrollment in this study

Note: Other protocol defined Inclusion/Exclusion criteria apply.
