The FDA granted the BTD based on data from the dose escalation portion and two expansion cohorts of a three-cohort phase 1 study of patritumab deruxtecan (cohorts 1 and 3a).

Key Points: 
  • The FDA granted the BTD based on data from the dose escalation portion and two expansion cohorts of a three-cohort phase 1 study of patritumab deruxtecan (cohorts 1 and 3a).
  • This is the first BTD for patritumab deruxtecan and the seventh BTD across Daiichi Sankyos oncology portfolio.
  • The Breakthrough Therapy Designation for patritumab deruxtecan acknowledges the need for new treatment approaches to overcome resistance and improve survival in patients with metastatic TKI-resistant, EGFR-mutated non-small cell lung cancer, said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo.
  • The global, multicenter, open label, two-part phase 1 study is evaluating patritumab deruxtecan in previously treated patients with metastatic or unresectable NSCLC.

The global, multicenter, open label, two-part phase 1 study is evaluating patritumab deruxtecan in previously treated patients with metastatic or unresectable NSCLC.

Key Points: 
  • The global, multicenter, open label, two-part phase 1 study is evaluating patritumab deruxtecan in previously treated patients with metastatic or unresectable NSCLC.
  • The dose expansion part of the study is evaluating patritumab deruxtecan at the RDE (5.6 mg/kg every three weeks) in three cohorts.
  • Cohort 2 includes patients with squamous or non-squamous NSCLC without EGFR-activating mutations following platinum-based chemotherapy and following an anti-PD-1 or anti-PD-L1 antibody regimen.
  • Secondary study endpoints include investigator-assessed objective response rate; safety, tolerability and preliminary efficacy; and characterization of the pharmacokinetics of patritumab deruxtecan.
