5. At least one measurable lesion on CT-scan (as per RECIST criteria V1.1).
6. Life expectancy ≥ 3 months
7. Adequate hematologic function (neutrophils ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L; Hb ≥ 9.0 g/dL), renal function (clearance creatinine using the CKD-EPI formula (Chronic Kidney Disease Epidemiology group) ≥ 60 mL/min) and hepatic function (serum bilirubin ≤ 1 ULN; AST and ALT ≤ 2.5 x ULN).
8. Potentially reproductive patients must agree to use an effective contraceptive method while on treatment, beginning 2 weeks before the first dose of investigational product and for 6 months after the final dose of investigational product.
9. Women of childbearing potential must have a negative serum beta-HCG pregnancy test within 14 days prior of enrolment and/or urine pregnancy test within 48 hours before the first administration of the study treatment.

Exclusion Criteria:

1. Active concurrent malignancy
2. Progression in the 3 months after the completion of treatment for localized disease
3. Patients with other concurrent severe and/or uncontrolled medical disease which could compromise participation in the study, such as :

   * infection,
   * cardiac disease such as uncontrolled hypertension, congestive cardiac failure, ventricular arrhythmias, active ischemic heart disease, myocardial infarction within one year, LVEF \> grade 2,
   * current active hepatic or biliary disease (with exception of subjects with Gilbert's syndrome, asymptomatic gallstones, liver metastasis or stable chronic liver disease per investigator assessment),
   * renal disease,
   * active GI tract ulceration, malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel. Subjects with active, uncontrolled ulcerative colitis are also excluded,
   * severely impaired lung function (spirometry and DLCO 70% or less of normal and O2 saturation of 88% or less at rest on room air).
4. Patients must have recovered of previous toxicity of chemotherapy and must not have toxicity grade \> 1 ; grade ≥ 2 for neuropathy and grade ≥ 2 for cutaneous rash after cetuximab (in the CTCAE v4.0)

6. Pregnant women, women who are likely to become pregnant or are breast-feeding.
7. Patients with significantly altered mental status prohibiting the understanding of the study or with psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
8. Patients who received any other investigational drugs within the 14 days prior to the start of cabazitaxel.
9. Patients receiving radiation within 4 weeks prior to the first dose of study drug.
10. Patients already included in another therapeutic trial involving an experimental drug
11. Individual deprived of liberty or placed under the authority of a tutor.
12. Other primary tumors within the previous 3 years
13. Concomitant prohibited treatment. Concurrent or planned treatment with strong inhibitors or strong inducers of cytochrome P450 3A4/5. A one week wash-out period is necessary for patients who are already on these treatments.
