Evaluation of SAR408701 in Patients With Advanced Solid Tumors

Inclusion criteria: * Locally advanced or metastatic solid malignant tumor disease for which no standard alternative therapy is available. * Availability of archived tumor tissue for carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5 or CEA) testing. * For participants in the Dose Escalation Cohorts (Main Escalation and Loading Dose Cohorts at every 2 week cycle and Dose Escalation every 3 week cycle): patients with tumors expressing or likely to be expressing CEACAM5 which includes colorectal cancer (CRC), non-squamous non-small cell lung cancer (NSCLC), gastric adenocarcinoma, squamous cell carcinoma of the cervix, pancreas adenocarcinoma, bladder transitional cell carcinoma, cholangiocarcinoma, epithelial ovarian cancer and endometrial adenocarcinoma are favored, or if carcinoembryonic antigen (CEA) plasma levels \>5 ng/mL. * For participants to the Expansion Phase cohorts: patients with CRC or with CEACAM5 positive non-squamous NSCLC, small cell lung cancer (SCLC) or gastric carcinoma (including esophago-gastric junction adenocarcinoma of the Siewert types II and III). * At least one measurable lesion by RECIST v1.1 in the Expansion Phase only. * At least one lesion amenable to biopsy (Expansion cohort - CRC and gastric cancer only). Patient must consent to a baseline biopsy for retrospective confirmation of tumor CEACAM5 expression, except if NSCLC or SCLC without lesion amenable to biopsy. * Signed informed consent. Exclusion criteria: * Aged less than 18 years. * Eastern Cooperative Oncology Group (ECOG) performance status more than 1. * New or progressing brain involvement. * Concurrent treatment with any other anticancer therapy or inadequate wash-out period for prior anticancer therapies before first administration of SAR408701, or non-resolution of toxicities induced by these anticancer therapies. * Female or male patients with reproductive potential who do not agree to use an accepted effective method of contraception during the study treatment period and for at least 3 months following completion of study treatment. * Pregnancy or breast-feeding. * Participation to any clinical research study evaluating another investigational drug or therapy within 3 weeks of initiation of study regimen. * Prior therapy targeting CEACAM5. * Prior maytansinoid treatments (DM1 or DM4 antibody drug conjugates). * Poor bone marrow reserve resulting in low blood cell counts. * Poor kidney and liver functions. * Any of the following within 6 months prior to study enrolment: infectious or inflammatory bowel disease, diverticulitis, gastrointestinal perforation, intestinal obstruction, and gastrointestinal hemorrhage. Patients with malabsorption syndrome are excluded. * Previous history and or unresolved corneal disorders. The use of contact lenses is not permitted. * Unresolved signs and symptoms of neuropathy; Grade 1 is acceptable if prior neurotoxic drugs such as cisplatin or taxanes. * Abnormal cardiac function defined by a left ventricular ejection fraction (LVEF) of \<50%. * Cardiac conduction defects, or any other clinically significant arrhythmias. * Known intolerance to infused protein products. * Medical conditions requiring concomitant administration of medications with narrow therapeutic window, metabolized by cytochrome P450 (CYPs) enzymes and for which a dose reduction cannot be considered. * Medical conditions requiring concomitant administration of strong CYP3A inhibitor, unless it can be discontinued at least 2 weeks before 1st administration of SAR408701. * Contraindications to the use of ophthalmic vasoconstrictor and/or corticosteroid as per package insert of each drug, including the following: increase intraocular pressure, prior or current glaucoma, narrow-angle glaucoma, ongoing eye infection, uncontrolled hypertension, known/suspected allergy to constituents of the preparation (such as sodium bisulfite).
