Official title

A Randomised, Open-label, Phase 3 Trial Comparing the Efficacy and Safety of OSE2101 Versus Docetaxel in HLA-A2 Positive Patients With Metastatic Non-Small Cell Lung Cancer (NSCLC) With Secondary Resistance to Immune Checkpoint Inhibitor

Overview

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).

Interventions

Drug OSE2101
OSE2101 is a peptidic cancer vaccine composed of nine epitopes restricted to HLA-A2 phenotype targeting the tumor associated antigens of P53, HER-2, CEA, MAGE-2 and MAGE-3, and one pan-HLA DR binding epitope (PADRE), all epitopes emulsified in Montanide ISA 51TM adjuvant.
Drug Docetaxel
Docetaxel is an antineoplastic agent that acts by disrupting the microtubular network in cells that is essential for mitotic and interphase cellular functions.
Device NGS HLAA2 assay
Amp-HLA-A-CDx Tedopi for amplification of human genomic DNA (gDNA), LFK-CDx Tedopi kit (library full kit) for library preparation, NGSengine-CDx Tedopi software for analysis of NGS data files.

Primary outcome measures

OS defined as time from randomization to death [Time frame: From randomization date through study completion, an average of 3 years]

Eligibility criteria

Inclusion criteria

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;

Other inclusion and exclusion criteria will apply per protocol.
