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

Up to 187 patients will be recruited in the TACTI-002 (Two ACTive Immunotherapies) Phase II study which will take place across approximately 22 study centres in the U.S., Europe and Australia. It will evaluate the safety and efficacy of the combination of eftilagimod alpha with pembrolizumab in patients with advanced or metastatic non-small cell lung carcinoma or head and neck carcinoma. It will be a Simon's two-stage, non-comparative, open-label, single-arm, multicentre clinical study. Patients participating in the trial will be given the combination treatment for 12 months using a 30 mg s.c. eftilagimod alpha dosing every 2 or 3 weeks.
