Study Description

Brief Summary: This study evaluates the efficacy, safety and pharmacokinetics of tinostamustine (EDO-S101) in patients with relapsed/refractory hematologic malignancies. All patients will receive tinostamustine.

Detailed Description: Tinostamustine is a First-in-Class Alkylating Histone Deacetylase Inhibition (HDACi) Fusion Molecule. It is anticipated that tinostamustine may have activity in various hematological malignancies and solid tumors. The study consists of 2 stages: * Stage 1: Dose Escalation to determine Maximum Tolerated Dose (MTD) at the optimal infusion time and the pharmacokinetic (PK) profiles; is expected to enroll between 21 and 48 patients. Stage 1 has now been completed. * Stage 2: Expansion in five Cohorts, in which approximately 12-16 patients will be enrolled per cohort, for a maximum of 70 patients. In Stage 1, tinostamustine doses were escalated following the standard 3+3 design. The decision to escalate to the next dose level occurred after all cohort patients completed 3 weeks (21 days) of observation and have been evaluated for safety and toxicity.The starting dose was a 1 hour infusion of 20 mg/m2, and the maximum dose level was 150 mg/m2. Reduced infusion times of 45 minutes and 30 minutes were assessed once the maximum tolerated dose at a 1-hour infusion was determined. In Stage 2, five cohorts of patients (with relapsed/refractory multiple myeloma (MM); relapsed/refractory Hodgkin's lymphoma; relapsed/refractory peripheral T-cell lymphoma (PTCL); relapsed/refractory cutaneous T-cell lymphoma (CTCL); and relapsed/refractory T-cell Prolymphocytic leukemia (T-PLL) will be enrolled and treated at the recommended Phase 2 dose (RP2D) based on results of Stage 1. For MM patients, treatment will occur on Day 1 and Day 15 of a 28 day cycle. For lymphoma patients, treatment will occur on Day 1 of a 21 day cycle. Patients in each stage of the study are expected to receive a median of four Cycles of therapy, and the maximum number of treatment Cycles allowed is 12. A sub study portion was added to the protocol as an amendment. In the sub study 6 patients will be treated with 100mg/m2 tinostamustine infusion delivered over 100 minutes.
