Trial Outcomes & Findings for Combination Study With Soluble LAG-3 Fusion Protein Eftilagimod Alpha (IMP321) and Pembrolizumab in Patients With Previously Untreated Unresectable or Metastatic NSCLC, or Recurrent PD-X Refractory NSCLC or With Recurrent or Metastatic HNSCC (NCT NCT03625323)

NCT ID: NCT03625323

Last Updated: 2024-12-18

Results Overview

ORR was defined as the percentage of participants for each dose level whose best overall response is rated as iCR or iPR per immune Response Evaluation Criteria In Solid Tumors (iRECIST) for target lesions and assessed by CT or MRI. iCR was defined as disappearance of all target and non-target lesions and any pathological lymph nodes must be \<10 mm in the short axis. iPR was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters.
