Multicenter, randomized (2:1), open-label phase 3 study in HLA-A2 positive patients with squamous and non-squamous metastatic NSCLC with ICI secondary resistance.
Patients will be randomized into 2 arms (randomization 2:1): experimental Arm A with OSE2101 monotherapy or control Arm B SoC with docetaxel monotherapy. Stratification factors will be histology (squamous versus non squamous) and ECOG Performance Status (0 versus 1).
Male or female, aged ≥ 18 years
Patients expressing HLA-A2 phenotype in blood by pre-screening central laboratory
Patients with histologically or cytologically squamous or non-squamous documented NSCLC, metastatic stage at study entry, not eligible for definite surgery or radiation, without EGFR, ALK and ROS1 gene alterations eligible for targeted therapy; for patients with squamous NSCLC, the molecular tests are not mandatory if age ≥ 50 years old and smoker ≥ 15 pack years; other sensitizing mutations known to be immunosensitive are eligible in case of lack of local access to targeted therapy (i.e.; KRAS G12C and BRAF mutations) after Sponsor' agreement.
Patients with secondary resistance to ICI;
None
