Descriptive Information
Brief Title  ICMJE Study of Tinostamustine, First-in-Class Alkylating HDACi Fusion Molecule, in Relapsed/Refractory Hematologic Malignancies
Official Title  ICMJE A Phase 1 Trial to Investigate the Safety, Pharmacokinetic Profiles and the Efficacy of Tinostamustine, a First-in-Class Alkylating Histone Deacetylase Inhibition (HDACi) Fusion Molecule, in Relapsed/Refractory Hematologic Malignancies
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 new chemical entity, a first-in-class fusion molecule of an alkylator, bendamustine and a histone-deacetylase inhibitor (HDACi), vorinostat. 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.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Patient willing and able to sign an informed consent.
  2. Patients age ≥18 years at signing the informed consent.
  3. Life expectancy > 3 months.
  4. Diagnosis of relapsed or refractory lymphoid malignancy for which there are no available therapies.
  5. Eastern Cooperative Oncology Group (ECOG) performance status ≤2
  6. Absolute Neutrophil Count >1,000 µL
  7. Platelets ≥100,000 µL
  8. Aspartate aminotransferase/alanine aminotransferase (AST/ALT) ≤2.5 upper limit of normal (ULN).
  9. Total bilirubin <2.0 mg/dL unless elevated due to known Gilbert's syndrome.
  10. Creatinine ≤1.5 x ULN.
  11. Serum potassium and magnesium at least at the lowest limit of normal (LLN) at baseline(before every IMP administration; if it is below LNN, (supplementation is permissible).
  12. Males and females of child-bearing potential, and their partners, must be willing to use at least two effective forms of birth control during the study drug administration and for at least 90 days after the administration of the study drug to be eligible to participate. Vasectomized partners and patients must be willing to use a secondary method of effective birth control. Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient.
