Brief summary

Primary Objectives: * Study was designed with multiple primary endpoints analyzed on randomized participants at the time of the cut-off date for each given analysis (progression free survival \[PFS\] and overall survival \[OS\]) * Study success was defined either on PFS or OS * The primary objective was to determine whether tusamitamab ravtansine improves the progression free survival (PFS) when compared to docetaxel in participants with metastatic non-squamous non-small-cell lung cancer (NSCLC) expressing CEACAM5 greater than or equal to 2+ in intensity in at least 50% of the tumor cell population and previously treated with standard-of-care platinum-based chemotherapy and an immune checkpoint inhibitor (ICI) * The primary objective was to determine whether tusamitamab ravtansine improves the overall survival (OS) when compared with docetaxel in participants with metastatic non-squamous NSCLC expressing CEACAM5 greater than or equal to 2+ in intensity in at least 50% of the tumor cell population and previously treated with standard-of-care platinum-based chemotherapy and an immune checkpoint inhibitor. Secondary Objectives: * Compared the objective response rate (ORR) of tusamitamab ravtansine with docetaxel * Compared the health-related quality of life (HRQOL) of tusamitamab ravtansine with docetaxel * Evaluated the safety of tusamitamab ravtansine compared to docetaxel * Assessed the duration of response (DOR) of tusamitamab ravtansine as compared with docetaxel

Detailed description

The median expected duration of study per participant was estimated as median 9 months in docetaxel arm (1 month for screening, 4 months for treatment, and 4 months for the EOT and follow-up visits) and 12.5 months in SAR408701 arm (1 month for screening, 6.5 months for treatment, and 5 months for end of treatment follow-up).

Progression-free Survival (PFS)Tumor assessments performed at screening, and every 8 weeks +/-5 days thereafter, up to 189 weeksPFS was defined as the time from the date of randomization to the date of the first documentation of objective PD as assessed by radiological review committee (IRC) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) definitions or death due to any cause before the study cut-off date, whichever occurred first. PD was defined as unequivocal progression of existing non-target lesions; appearance of 1 or more new lesions; at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm).

CR was defined as disappearance of all target and non-target lesions, and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have had reduction in short axis to \<10 mm.

For the TTD in disease-related symptoms (cough, dyspnea, pain) from EORTC QLQ LC-13, a deterioration was defined as an increase from baseline score of at least 10 points in any 1 of these 3 symptoms. The EORTC QLQ-LC13 (LC13) is the lung cancer module of the EORTC QLQ-C30 that assesses lung-cancer-associated symptoms (cough, dyspnea, pain, hemoptysis) and side-effects from conventional chemotherapy and radiotherapy (sore mouth, hair loss, dysphagia and neuropathy). The EORTC QLQ-LC13 contains 13 items. Items on the LC13 were scored using the LC13 scoring algorithms which standardize the raw scores to a 0-100 range. Lower scores indicate lower symptomology/symptom burden (lower scores better).

The TTD was defined as the time from baseline (Cycle 1, Day 1) until the first ≥10-point change from baseline up to the end of treatment assessment before the initiation of further anticancer therapy and the analysis cut-off date. For the TTD in disease-related symptoms (cough, dyspnea, pain) from EORTC QLQ LC-13, a deterioration was defined as an increase from baseline score of at least 10 points in any 1 of these 3 symptoms. The EORTC QLQ-LC13 (LC13) is the lung cancer module of the EORTC QLQ-C30 that assesses lung-cancer-associated symptoms (cough, dyspnea, pain, hemoptysis) and side-effects from conventional chemotherapy and radiotherapy (sore mouth, hair loss, dysphagia and neuropathy). The EORTC QLQ-LC13 contains 13 items. Items on the LC13 were scored using the LC13 scoring algorithms which standardize the raw scores to a 0-100 range. Lower scores indicate lower symptomology/symptom burden (lower scores better).
