Neoplasm Malignant
Conditions
Brief summary
Primary Objectives: To determine the maximum tolerated dose (MTD) of SAR428926 when administered as a single agent in patients with advanced solid tumors. To evaluate the anti-tumor response of SAR428926 when administered as a single agent in patients with advanced triple negative breast cancer (TNBC) positive for the protein targeted by SAR428926 To assess the preliminary anti-tumor response of SAR428926 when administered as a single agent in patients with advanced solid tumors positive for the protein targeted by SAR428926 Secondary Objectives: To determine the overall safety profile of SAR428926 as a single agent. To characterize the pharmacokinetics (PK) profile of SAR428926 and its metabolites. To identify the recommended Phase 2 dose (RP2D) of SAR428926 as a single agent. To evaluate the immunogenicity of SAR428926. To assess the tumor response and duration of tumor response in all treated patients. To evaluate the benefit of primary prophylaxis on the occurrence of corneal (keratopathy/keratitis) toxicity (Expansion cohorts).
Detailed description
The study duration for an individual patient will include a screening period for inclusion of up to 28 days, a treatment period, an end-of-treatment (EOT) visit around 30 days following the last administration of SAR428926, and at least one follow-up visit around 30 days after the EOT visit. The treatment period may continue until disease progression, intolerable toxicity, or investigator, Sponsor, or patient decision to discontinue therapy. Patients who discontinue treatment for reasons other than progression of disease will be followed every 3 months until progression, initiation of subsequent therapy, or until the primary analysis cutoff date, whichever comes first.

Inclusion criteria
: * Patients with advanced solid tumor with no standard alternative treatment. * Availability of archived tumor tissue for SAR428926 targeted antigen testing. * For participants in the Escalation Phase: human epidermal growth factor receptor 2 (HER2) negative breast cancer (BC), gastric cancer, colorectal cancer (CRC), ovarian cancer, prostate cancer and non small-cell lung cancer (NSCLC). * For participants in the Expansion Phase: patients with TNBC, prostate cancer, CRC, ovarian cancer or NSCLC and positive SAR428926 targeted antigen. * At least one measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and one lesion amenable to biopsy in expansion cohort only (except for NSCLC patients).
Exclusion criteria
* Age less than 18 years old. * Eastern Cooperative Oncology Group (ECOG) performance status more than 1. * New or progressing brain metastases. * Concurrent treatment with any other anticancer therapy or inadequate wash-out period for prior anticancer therapies, including other experimental anticancer treatment, before first administration of SAR428926, or non resolution of toxicities induced by these anticancer therapies. * Women of reproductive potential and male subjects with female partners of childbearing potential who are not willing to avoid pregnancy. * Pregnancy or breast feeding. * Prior maytansinoid treatments (DM1 or DM4 antibody drug conjugates \[ADCs\]). * Unwillingness and inability to comply with scheduled visits, drug administration plan, laboratory tests, other study procedures, and study restrictions. * Significant concomitant illness, including psychiatric condition that, in the opinion of the Investigator or Sponsor, would adversely affect the patient's participation in the study. * Any surgery within the preceding 3 weeks. * Known human immunodeficiency virus (HIV) infection or active hepatitis B or C viral infection. * Poor bone marrow reserve. * Poor kidney and liver function. * Previous history of chronic corneal diseases (even if asymptomatic) or unresolved acute non-recurrent corneal conditions. Patients wearing contact lenses who are not willing to stop wearing them for the duration of the study. * Unresolved signs and symptoms of peripheral neuropathy; Grade 1 is acceptable. * Abnormal cardiac function defined by a left ventricular ejection fraction (LVEF) \<50%. * Known intolerance to infused protein products including other monoclonal antibodies and ADCs. * Medical conditions requiring concomitant administration of medications with narrow therapeutic window, metabolized by CYPs and which a dose reduction cannot be considered. * Medical conditions requiring concomitant administration of strong CYP3A inhibitors, unless it can be discontinued at least two weeks before first administration of SAR428926. * Other prior neoplasm. * 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).
