Safety and Pharmacokinetic Study of Cabazitaxel in Patients With Advanced Solid Tumors and Liver Impairment

Phase I Safety and Pharmacokinetic Study of XRP6258 (Cabazitaxel) In Advanced Solid Tumor Patients With Varying Degrees of Hepatic Impairment

Primary Objectives:

• To determine the maximum tolerated dose (MTD) and safety of Cabazitaxel when administered to advanced solid tumor patients with varying degrees of hepatic impairment
• To determine the pharmacokinetics (PKs) of Cabazitaxel in patients with varying degrees of hepatic impairment
• To correlate PK variables with pharmacodynamic (PD) safety parameters in order to guide prescribers with regard to dosing in this patient population
• To assess the effect of cabazitaxel at recommended dose of 25mg/m^2 on CYP3A enzyme activity using midazolam as probe in an additional cohort of cancer patients with normal hepatic function.

Study Overview

• Status: Completed
• Conditions: Neoplasm Malignant
• Intervention / Treatment: Drug: Cabazitaxel (XRP6258)

Detailed Description

The study consists of:

• a screening phase (maximum length of 21-day).
• a treatment phase with 21-day study treatment cycles. Cycle lengths may be extended up to maximum of 12 additional days in case of unresolved toxicity.

Patients continue to receive treatment until they experience, unacceptable toxicities/AEs, disease progression ,withdraw their consent, or the investigator decides to discontinue the patient, or study cut-off, whichever comes first.

• a 30-day follow-up visit after the last dose of study medication.

The cut off date is when the last patient treated has completed cycle 1 and the subsequent 30 days follow-up.

Patients may continue to be treated as long as they are benefiting from study treatment and have not met study withdrawal criteria.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 60 years (Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion criteria:

• Patients with a diagnosis of advanced, measurable or non-measurable, non-hematological cancer who have varying degrees of hepatic impairment. The cancer must be one that is either refractory to standard therapy or for which no standard therapy exists.

Exclusion criteria:

• Eastern Cooperative Oncology Group (ECOG) performance status (PS) >2
• Life expectancy <3 months
• Need for a major surgical procedure or radiation therapy during the study
• Evidence of another active malignancy
• Prior chemotherapy, other investigational drug, biological therapy, targeted non-cytotoxic therapy and radiotherapy within 3 weeks prior to registration
• Patients with known history of Gilbert's syndrome
• Prior treatment with Cabazitaxel and a history of severe (Grade ≥3) hypersensitivity to taxanes, polysorbate-80, or to compounds with similar chemical structures
• Prior history of bone marrow transplant
• Any treatment known to induce CYP isoenzymes or to inhibit CYP3A4 activities within 2 weeks before or during the test period of the pharmacokinetic sampling. Moderate inhibitors within one week prior and during the pharmacokinetic sampling.
• Any contra-indications to midazolam, according to the applicable labeling.
