Original description

This is a phase 1a/1b, multicenter, single-arm, open-label, dose escalation study to determine the maximum tolerated dose (MTD) and evaluate the safety and preliminary antitumor activity of ACY-241 for oral administration as monotherapy and in combination therapy with orally administered pomalidomide and low-dose dexamethasone in eligible patients with relapsed or relapsed-and-refractory multiple myeloma (MM).Read full original descriptionShow less

A Phase 1a/1b Multicenter, Single-Arm, Open-Label, Dose-Escalation Study to Determine the Maximum Tolerated Dose, Safety, and Preliminary Activity of Oral ACY-241 Alone and in Combination With Pomalidomide and Low-Dose Dexamethasone in Patients With Relapsed or Relapsed-and-Refractory Multiple Myeloma

This is a phase 1a/1b, multicenter, single-arm, open-label, dose escalation study to determine the maximum tolerated dose (MTD) and evaluate the safety and preliminary antitumor activity of ACY-241 for oral administration as monotherapy and in combination therapy with orally administered pomalidomide and low-dose dexamethasone in eligible patients with relapsed or relapsed-and-refractory multiple myeloma (MM).

Inclusion: Must have a documented diagnosis of MM and have relapsed or relapsed-and-refractory disease. All patients must have relapsed after having achieved at least stable disease (SD) for at least 1 cycle of treatment to at least 1 prior regimen and then developed progressive disease (PD). Relapsed-and-refractory patients also have documented evidence of PD during or within 60 days of completing last treatment; Must have undergone prior treatment with at least 2 cycles of lenalidomide and at least 2 cycles of proteasome inhibitor unless not a candidate; May have undergone prior treatment with pomalidomide if patient is not refractory to pomalidomide and has previously achieved a response of MR or better to pomalidomide; Must have measurable disease (serum M-protein or urine M-protein); Must have Eastern Cooperative Oncology Group (ECOG) Performance score of 0, 1, or 2; Must be able to take low-dose aspirin, low molecular weight heparin, or other equivalent antithrombotic or anticoagulant daily as prophylactic anticoagulation.

Exclusion: Prior therapy with pomalidomide with best response of PD or SD; Prior therapy with histone deacetylase (HDAC) inhibitor; Patients who received an allogeneic bone marrow or allogeneic peripheral blood stem cell transplant less than 12 months prior to initiation of study; Hypersensitivity to thalidomide, lenalidomide, pomalidomide, or dexamethasone; Any of the following laboratory abnormalities: Absolute neutrophil count(ANC) < 1,000/µL, Platelet count < 75,000/µL or < 50,000/µL for patients in whom ≥ 50% of bone marrow nucleated cells are plasma cells, Hemoglobin < 8 g/dL, Creatinine clearance < 45 mL/min according to Cockcroft-Gault formula. If creatinine clearance calculated from the 24 hour urine sample is ≥ 45 mL/min, patient will qualify for the trial, Aspartate transaminase (AST) or Alanine transaminase (ALT) > 3.0 × Upper Limited Normal (ULN), Serum total bilirubin > 2.0 mg/dL or > 3.0 × ULN for patients with hereditary benign hyperbilirubinaemia; Nonsecretory myeloma or free light chain detected in serum only (ogliosecretory); Hematologic growth factors are not allowed at screening or during the first cycle of phase 1a or 1b.
