Primary Objective:

• To assess the potential effect on QTcF interval (QTc Fridericia) of cabazitaxel in cancer patients

Secondary Objectives:

• To assess the effects of cabazitaxel on heart rate (HR), QT, QTcB (Bazett's correction), and QTcN (population specific correction) intervals
• To assess the clinical safety of cabazitaxel
• To assess cabazitaxel plasma concentrations at Cycle 1 at early timepoints (during infusion and up to 5h post end of infusion)

The main period of the study consists of a maximum of 21-day screening phase, then first 2 treatment cycles with cabazitaxel. End of main period will be Cycle 3 or 30 days after last dose if patient discontinues study after 1 or 2 treatment cycles. The duration for a patient for the main period of the study will be about 9 to 10 weeks (screening, 2 cycles).

After Cycle 2, patients will have the option to continue to receive cabazitaxel and should be followed for safety reporting until 30 days after the last dose of cabazitaxel.

Inclusion criteria:

• Histologically or cytologically confirmed solid malignancy that is metastatic or unresectable, and for which standard curative measures do not exist, and a treatment with a novel taxane agent is considered.

Exclusion criteria:

• Conditions with screening ECG repolarization difficult to interpret, or showing significant abnormalities. This includes, but is not limited to: high degree AV block, pace-maker, atrial fibrillation or flutter
• QTcF >480 msec on screening Electrocardiogram (ECG)
• Significant hypokalemia at screening (serum potassium <3.5 mMol/L)
• Significant hypomagnesemia at screening (serum magnesium <0.7 mMol/L) (Note: Patient may be enrolled after correction of these laboratory abnormalities)
• Patient receives (and cannot discontinue), or is scheduled to receive a QT-prolonging drug

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
