Details and patient eligibility

About

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).

Inclusion and exclusion criteria

Inclusion Criteria:

  1. Male or female, aged ≥ 18 years

  3. 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; 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's agreement
  4. Patients with secondary resistance to ICI;

Other inclusion and exclusion criteria will apply per protocol.
