Dose-escalation Study of Oral Administration of S 55746 in Patients With Chronic Lymphocytic Leukaemia and B-Cell Non-Hodgkin Lymphoma

Phase 1
Completed
Conditions
Multiple Myeloma (MM)
Chronic Lymphocytic Leukaemia (CLL)
B-Cell Non-Hodgkin Lymphoma (NHL)
Interventions
Drug: S 55746
Registration Number
NCT02920697
Lead Sponsor
Institut de Recherches Internationales Servier
Brief Summary

The purpose of this study is to determine the safety profile and tolerability of S 55746 in patients with CLL, B-Cell NHL and MM, in terms of Dose-Limiting Toxicities (DLTs), Maximum Tolerated Dose (MTD) and determine the Recommended Phase 2 Dose (RP2D) through safety profile (DLT, MTD), PK profile, PD profile and preliminary efficacy.

Primary Outcome Measures
NameTimeMethod
Maximum Tolerated Dose (MTD)During cycle 1 (21 days)

The MTD is the highest drug dosage that is unlikely (\<25% posterior probability) to cause DLT in more than 33% of the treated patients in the first cycle of S 55746 treatment

Incidence of Adverse Events (AEs)From first dose until 30 days after the last dose intake

Characterized by severity and seriousness of AEs, laboratory abnormalities and other safety parameters such as electrocardiogram (ECG) changes

Secondary Outcome Measures
NameTimeMethod
Apoptotic activity from blood samplesAt Cycle 1(21 days)
Objective Response Rate (ORR)Up to study completion (maximum of 3 years)
The pharmacokinetic (PK) profile of S 55746: Area Under the Curve [AUC]Pre-dose on Cycle 1 Day 1 (C1D1), C1D2, C1D3, C1D4, C1D5, C1D8, C1D9, C2D1 ; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10-12 hours post-dose on C1D1, C1D8
Progression Free Survival (PFS)From date of inclusion until the date of progression or date of death, whichever occurs first, assessed up to study completion (maximum of 3 years)
Plasma concentration of S 55746Pre-dose on Cycle 1 Day 1 (C1D1), C1D2, C1D3, C1D4, C1D5, C1D8, C1D9, C2D1 ; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10-12 hours post-dose on C1D1, C1D8
The PK profile of S 55746: Maximal Concentration [Cmax]Pre-dose on Cycle 1 Day 1 (C1D1), C1D2, C1D3, C1D4, C1D5, C1D8, C1D9, C2D1 ; 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10-12 hours post-dose on C1D1, C1D8
