About

Primary Objective:

To determine the maximum tolerated dose (MTD) of SAR566658

Secondary Objectives:

To characterize the safety profile of SAR566658
To evaluate the pharmacokinetic profile of SAR566658
To assess the potential immunogenicity of SAR566658
To assess preliminary antitumor activity
To assess the effect of SAR566658 at recommended dose on CYP3A enzyme activity using midazolam
To assess safety in the alternative schedules of SAR566658 administration

Full description

The duration of the study for one patient in the dose escalation phase of the study will include a screening period of up to 3 weeks, a 3-week treatment cycle(s) and a 2-week treatment cycle(s). The patients may continue treatment until disease progression, unacceptable toxicity, or willingness to stop, followed by a minimum of 30-day follow-up. If a patient treated in dose escalation part or in an expansion cohorts, continues to benefit from the treatment at the time of Clinical Study Report, the patient can continue study treatment and will continue to undergo all assessments as per the study flowchart. Such patients will be followed at least until 30 days after the last IMP administration.

Patients with previous history or active interstitial lung disease or pulmonary fibrosis.
Patients with abnormal cardiac function defined by a Left Ventricular Ejection Fraction <50%.
Patients with previous history of acute cardiac failure.
Patients with previous history and/or unresolved corneal disorders.
Known intolerance to infused protein products or maytansinoids.
Patients treated with strong CYP3A inhibitors within 2 weeks prior study drug administration.
For patients to be treated in the midazolam cohort:
Any treatment known to induce CYP3A isoenzymes or to inhibit CYP3A4 activities not allowed within 2 weeks before midazolam administration and up to the end of pharmacokinetic sampling following the last midazolam administration.
Any contra-indications to midazolam, according to the applicable labeling.
Patients older than 60 years.
