      Background

      Immunotherapy has significantly changed the treatment landscape of non-small cell lung cancer (NSCLC) with no driver mutations. However, despite the addition of anti-PD-1/PD-L1 therapies to the clinical armamentarium only a subset of patients derives durable benefit. IO102 is a novel, second generation, HLA-A unrestricted immune modulating T-win® vaccine targeting IDO. IO102 has a dual mode of action; remodulation of the tumour micro-environment through elimination of immune suppressive cells, and induction of CD8 T-cell mediated killing of IDO-expressing tumor cells. Our first-generation IDO vaccine (IO101) has shown promising antitumor activity and a favorable safety in heavily pretreated NSCLC patients (Iversen, CCR 2013).

      Method

      Phase I/II, international, multicenter, open-label, randomized trial with two parallel cohorts. Cohort A: IO102 (100µg s.c.) and pembrolizumab (200 mg) (PD-L1 ≥ 50%); Cohort B: IO102, pembrolizumab and carboplatin plus pemetrexed (PD-L1 < 50%). The maximum treatment duration is 35 cycles (app. 2 years). Key eligibility criteria include metastatic NSCLC or non-squamous NSCLC (cohort B) with no prior treatment for metastatic NSCLC and no driver mutations.

      Phase I is a non-randomized safety run-in with 6 patients per cohort investigating one dose level of the experimental arms. Only one DLT is allowed in each cohort. Phase II is following Sargent’s two-stage, three-outcome optimum design (Sargent, ClinTrial2001) with a 2:1 randomization in the cohorts. Cohort A: IO102 and pembrolizumab versus pembrolizumab alone; Cohort B: IO102, pembrolizumab and chemotherapy vs. pembrolizumab and chemotherapy. Provision of blood and tumour tissue is required for biomarker studies.

      The primary endpoint is safety and objective response rate (ORR) per RECIST 1.1 in Phases I and II, respectively. Secondary endpoints include ORR per iRECIST, duration of response, progression free survival, overall survival, and biomarkers including immunoscore in tissue, tumour mutational burden and immunomonitoring in blood.

      The study is enrolling in Europe. First patient was entered in September 2018 and recruitment is expected to continue throughout 2019: EudraCT Number 2018-000139-28 / IND Number: 018081.
