B-Cell Non-Hodgkin Lymphoma (NHL), Chronic Lymphocytic Leukaemia (CLL), Multiple Myeloma (MM)
Conditions
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.
Interventions
S 55746, per os administration, from 50 to 1500 mg, once a day during a 21-day cycle. Participants will receive 21-day cycles of treatment until a discontinuation criterion is met.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame |

| Apoptotic activity from blood samples | At Cycle 1(21 days) |
| Objective Response Rate (ORR) | Up to study completion (maximum of 3 years) |
| Plasma concentration of S 55746 | 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) |
| Clinical Benefit Rate (CBR) | 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 |
