OSE2101 Versus Chemotherapy in HLA-A2 Positive Patients With Advanced NSCLC After Immune Checkpoint Inhibitor Failure

Phase 3

Conditions

Interventions
Registration Number
NCT02654587
Lead Sponsor
OSE Immunotherapeutics
Brief Summary

The aim of this clinical trial was to determine if the therapeutic cancer vaccine OSE2101 (TEDOPI) was more effective than standard chemotherapy (docetaxel or pemetrexed) in treating HLA-A2 positive patients with metastatic NSCLC who progressed after sequential or concurrent chemotherapy and immune checkpoint inhibitor given in first or second-line treatment.

The main questions were to compare the survival, the tolerance to treatment and the quality of life of patients between the two arms of treatment (OSE2101 versus standard chemotherapy)

Detailed Description

The study was a two-step randomized (2:1) study. Patients were stratified by histology (non-squamous versus squamous), best response to first-line treatment \[complete response or partial response versus stable disease or progressive disease\] and line of treatment with prior ICI (first-line ICI when combined with platinum-based chemotherapy versus second-line ICI when administered as sequential treatment). Primary endpoint was overall survival (OS). Interim OS futility analysis was planned as per Fleming design. In April 2020 at the time of the interim analysis, a decision was taken to early stop the accrual due to COVID-19 after 219 out of 363 patients were randomized. It led to a decrease of the study power from 80% to 62%. At the time of the interim analysis, a subgroup of patients was identified from stratification factor based on a clinical and biological rationale: those who received ICI second line and having received at least 12 weeks ICI. This subgroup was defined as ICI secondary resistance. The final analysis was carried out in the subgroup of patients with ICI secondary resistance and in all patients (ICI primary and secondary resistance).

Docetaxel or PemetrexedPemetrexedPatients receiving docetaxel: Docetaxel 75 mg/m2 will be administered by intravenous infusion over 1 hour on Day 1 of a 21-day cycle. Patients receiving pemetrexed: Pemetrexed, 500 mg/m2, will be administered by intravenous infusion over 10 minutes on Day 1 of a 21-day cycle. Docetaxel and pemetrexed will be continued until unequivocal RECIST 1.1-defined disease progression as determined by the investigator, unacceptable toxicity, or consent withdrawal.
OSE2101OSE2101OSE2101 was administered as a 1 mL-subcutaneous injection on Day 1 every three weeks for six cycles, then every eight weeks for the remainder of year one and finally every twelve weeks beyond year one until unequivocal RECIST 1.1-defined disease progression as determined by the investigator, unacceptable toxicity, or consent withdrawal. Should pseudo progression or delayed response to treatment suspected in arm A, investigator may continue treatment beyond the time of RECIST-defined progression, if the patient is perceived to be experiencing clinical benefit of OSE2101. OSE2101 dose was 5 mg of peptides (0.5 mg for each peptide).

Primary Outcome Measures
NameTimeMethod
Overall Survival (OS)Approx. 24 months

OS defined as the time from randomisation to death from any cause in patients with ICI secondary resistance

Secondary Outcome Measures
NameTimeMethod
Mean Changes in Symptoms Subscales of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire (QLQ-C30) From Baseline to Treatment Discontinuation in Patients With ICI Secondary ResistanceApprox. 24 months

Mean change from baseline to treatment discontinuation in Quality of Life (QoL) score of the following symptoms subscales analyzed separately: Fatigue, Constipation, Dyspnea, Nausea and Vomiting, Pain, Insomnia, Appetite loss, Diarrhea, Financial Difficulties. Each score range from 0 to 100 after normalisation. Lowest scores correspond to a better QoL. The mean score change was assessed using a mixed-effects model for repeated measures analysis with the patient as the random effect, treatment, visit and treatment-by-visit interaction as explanatory variables and baseline score as covariates. If the mean score change is negative, it means a deterioration of QoL. If the mean score change is positive or 0, it means an improvement or stability of QoL.

Mean Changes in Symptoms Subscales of European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Lung Cancer (QLQ-LC13) From Baseline to Treatment Discontinuation in Patients With ICI Secondary ResistanceApprox. 24 months

Each score range from 0 to 100 after normalisation. Lowest scores correspond to a better QoL. The mean score change was assessed using a mixed-effects model for repeated measures analysis with the patient as the random effect, treatment, visit and treatment-by-visit interaction as explanatory variables and baseline score as covariates. If the mean score change is negative, it means a deterioration of QoL. If the mean score change is positive or 0, it means an improvement or stability of QoL.

Disease Control Rate (DCR) at 6 MonthsApprox. 6 months

DCR at 6 months defined as the number of patients with Complete Response (CR), Partial Response (PR) or Stable Disease (SD) assessed by investigator per "Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions based on CT scan in patients with ICI secondary resistance. Complete Response (CR) defined as disappearance of all target lesions; Partial Response (PR) as \>=30% decrease in the sum of the longest diameter of target lesions; Stable disease (SD) defined as neither sufficient shrinkage (compared to baseline) to qualify for CR or PR nor sufficient increase (taking as reference the smallest sum of diameters at baseline or while on study, whichever is smallest) to qualify for progressive disease (PD) (e.g. decrease of the sum of the longest diameters of target lesions \<30% or increase up to 20%)

Progression Free Survival (PFS) in Patients With ICI Secondary ResistanceApprox. 24 months

PFS was defined as the time from randomization to the earliest date of progression assessed by investigator per "Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions based on CT scan in patients with ICI secondary resistance. Progressive disease (PD) defined as increase of target lesions \>=20% taking as reference the smallest sum of diameters at baseline or while on study, whichever is smallest)

Post-Progression Survivalapproximately 24 months

Post-progression survival was defined as the time from the earliest date of progression according to RECIST 1.1 until death in patients with ICI secondary resistance

Time to Worsening ECOG PSApprox. 24 months

Time to Worsening ECOG PS was defined as the time from randomization to the earliest date when ECOG PS was \>1 in patients with ICI secondary resistance. Time to worsening ECPG PS was summarized by treatment arm using the Kaplan-Meier method. The median event time for each treatment arm and the corresponding 2-sided 95% confidence interval were provided. By protocol, ECOG PS was not collected when a patient permanenetly discontinued the study treatment. Patients without ECOG PS worsening were censored at the last time when an ECOG value was recorded.

Mean Changes in Functional Subscales of European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire (QLQ-C30) From Baseline to Treatment Discontinuation in Patients With ICI Secondary ResistanceApprox. 24 months

Mean change from baseline to treatment discontinuation in Quality of Life (QoL) score of the following functional subscales analyzed separately: global health status, physical, role, cognitive, emotional and social functioning. Each score range from 0 to 100 after normalisation. Highest scores correspond to a better quality of life. The mean score change was assessed using a mixed-effects model for repeated measures analysis with the patient as the random effect, treatment, visit and treatment-by-visit interaction as explanatory variables and baseline score as covariates. If the mean score change is negative, it means a deterioration of QoL. If the mean score change is positive or 0, it means an improvement or stability of QoL
