A phase 1b study of isatuximab plus lenalidomide and dexamethasone for relapsed/refractory multiple myeloma.

This phase 1b, open-label, dose-escalation study assessed the safety, efficacy, and pharmacokinetics of anti-CD38 monoclonal antibody isatuximab given in 2 schedules (3, 5, or 10 mg/kg every other week [Q2W] or 10 or 20 mg/kg weekly [QW] for 4 weeks and then Q2W thereafter [QW/Q2W]), in combination with lenalidomide 25 mg (days 1-21) and dexamethasone 40 mg (QW), in patients with relapsed/refractory multiple myeloma (RRMM). Patients received 28-day treatment cycles; the primary objective was to determine the maximum tolerated dose (MTD) of isatuximab with lenalidomide and dexamethasone. Fifty-seven patients (median 5 [range 1-12] prior regimens; 83% refractory to previous lenalidomide therapy) were treated.

Safety and pharmacokinetics of cabazitaxel in patients with hepatic impairment: a phase I dose-escalation study.

Purpose: Cabazitaxel has not been studied in patients with hepatic impairment (HI). This phase I study assessed cabazitaxel safety and pharmacokinetics in patients with HI.

Methods: Patients with advanced, non-hematologic cancer, and normal hepatic function (Cohort 1: C-1), or mild (C-2), moderate (C-3), severe (C-4) HI received cabazitaxel starting doses of 25, 20, 10, and 10 mg/m, respectively.

A phase I pharmacokinetic and safety study of cabazitaxel in adult cancer patients with normal and impaired renal function.

Purpose: Limited data are available on cabazitaxel pharmacokinetics in patients with renal impairment. This open-label, multicenter study assessed cabazitaxel in patients with advanced solid tumors and normal or impaired renal function.

Methods: Cohorts A (normal renal function: creatinine clearance [CrCL] >80 mL/min/1.

Phase I study of cabazitaxel plus cisplatin in patients with advanced solid tumors: study to evaluate the impact of cytochrome P450 3A inhibitors (aprepitant, ketoconazole) or inducers (rifampin) on the pharmacokinetics of cabazitaxel.

Purpose: Cabazitaxel is primarily metabolized by CYP3A. This study evaluated the impact of moderate/strong CYP3A inhibitors [aprepitant (Study Part 2); ketoconazole (Study Part 3)] or strong CYP3A inducers [rifampin (Study Part 4)] on the pharmacokinetics of cabazitaxel.

Methods: Adult patients received IV cabazitaxel/cisplatin 15/75 mg/m(2) on Day 1 of 3-week cycles (5/75 mg/m(2) in Cycles 1 and 2 of Part 3 to allow a safety margin to the cabazitaxel MTD).

Phase I dose-escalation study of cabazitaxel administered in combination with cisplatin in patients with advanced solid tumors.

Introduction: Cabazitaxel is a second-generation taxane with in vivo activity against taxane-sensitive and -resistant tumor cell lines and tumor xenografts. Cabazitaxel/cisplatin have therapeutic synergism in tumor-bearing mice, providing a rationale for assessing this combination in patients with solid tumors.

Methods: The primary objectives of this study were to determine dose-limiting toxicities (DLTs) and the maximum tolerated dose (MTD) of a cabazitaxel/cisplatin combined regimen (Part 1) and to assess antitumor activity at the MTD (Part 2).

Plateable cryopreserved human hepatocytes for the assessment of cytochrome P450 inducibility: experimental condition-related variables affecting their response to inducers.

Unlabelled: 1.

Rationale: The aim of the present study was to assess the stability of cryopreserved human hepatocytes over 5 years and to explore experimental condition-related variables such as seeding density, culture matrix and medium, start and duration of treatment that could potentially affect the quality of cultures and their response to cytochrome P450 (CYP) inducers. 2.
