Immunotherapy With Racotumomab in Advanced Lung Cancer

Recombio SL1,082 enrolled

Overview

This is a prospective, randomized, open label, parallel-group, multicenter phase III study to evaluate the efficacy and safety of active specific immunotherapy with racotumomab plus best supportive care versus best supportive care in patients with advanced NSCLC who have achieved an Objective Response (Partial or Complete Response) or Stable Disease with standard first-line treatment. Also immunological parameters will be evaluated. Best supportive therapy will be administered to all patients in the study according to institutional standards and includes any subsequent onco-specific therapies. 1082 patients will be included in the study, with non-small cell lung cancer in stages IIIA (non-resectable), IIIB or IV.

Conditions

NSCLC Lung Cancer, Non-small Cell

Interventions

Patients will receive best support treatment and vaccination with racotumomab. The vaccination schedule is as follows: 5 doses (1mg/mL each), intradermally, every 2 weeks (induction period) followed by monthly vaccinations until any criteria for discontinuation are met. If disease progression occurs and further onco-specific therapy is indicated, the patient will be able to continue in the study and vaccination will not be interrupted unless criteria for vaccine discontinuation are met.

Outcomes

Primary Outcomes

Overall Survival

A comparison of survival in the subgroup of inoperable stage IIIA and dry IIIB will be performed in 757 (approximately 70% of the study population)

Time frame: Until date of death or last censored observation, on average upto 17 months

Secondary Outcomes

Number of Participants with Adverse events as a measure of safety and tolerability

Safety will be evaluated at each study visit according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0 and will include physical examination with vital signs, performance status as per the Eastern Cooperative Oncology Group scale(ECOG scale), laboratory tests and clinical history.

Time frame: Until death, on average during 17 months

Progression Free Survival

Tumour evaluations will be performed every 2 months and evaluated as per Response Evaluation Criteria in Solid Tumors (RECIST).

Time frame: From randomization until date of first documented progression of disease, assessed as per RECIST 1.0 during an expected average of 17 months

Determination of IgM and IgG antibody titers against N-Glycolil-GM3 ganglioside

Time frame: Baseline
