Clinical Trial Summary

This clinical trial is for subjects with multiple myeloma that has returned after treatment (relapsed) or did not respond to prior treatment (refractory). The study is in two parts, Phase I and Phase II. Phase I will determine the maximum tolerated dose of romidepsin in combination with pomalidomide and dexamethasone. The purpose of Phase II is to evaluate the effectiveness of combining romidepsin with pomalidomide and dexamethasone. The hypothesis is that overall response in a cohort of patients treated with romidepsin + pomalidomide + dexamethasone will be 60 percent.

Description:

This phase I/II study is a treatment program for patients with relapsed or refractory multiple myeloma. Up to 48 patients will be enrolled. Phase I will follow a 3+3 dose escalation design to find the maximum tolerated dose of romidepsin in combination with pomalidomide and dexamethasone.

In Phase I, subjects will receive:

• Pomalidomide 4mg daily by mouth on days 1-21 of a 28-day cycle

• Dexamethasone 40mg by mouth on days 1, 8, 15 and 22 of a 28-day cycle

• Romidepsin intravenously (9 mg/m2, 12 mg/m2, 15 mg/m2 or 18 mg/m2) on days 1 and 15 of a 28-day cycle.

Phase II will expand the number of subjects in the MTD arm of the trial until 48 subjects are enrolled. In Phase II, subjects subjects will receive:

• Pomalidomide 4mg daily by mouth on days 1-21 of a 28-day cycle

• Dexamethasone 40mg by mouth on days 1, 8, 15 and 22 of a 28-day cycle

• Romidepsin intravenously on days 1 and 15 of a 28-day cycle at the Maximum Tolerated Dose determined by Phase I

Exclusion Criteria:

3. Myocardial infarction within 6 months of C1D1. Subjects with a history of myocardial infarction between 6 and 12 months prior to C1D1 who are asymptomatic and have had a negative cardiac risk assessment (treadmill stress test, nuclear medicine stress test, or stress echocardiogram) since the event may participate

5. Symptomatic coronary artery disease (CAD), e.g., angina Canadian Class II-IV. In any subject in whom there is doubt, the subject should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present

6. An ECG recorded at screening showing evidence of cardiac ischemia (ST depression depression of =2 mm, measured from isoelectric line to the ST segment). If in any doubt, the patient should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present

7. Congestive heart failure (CHF) that meets New York Heart Association (NYHA) Class II to IV definitions (see Appendix E) and/or ejection fraction <40% by MUGA scan or <50% by echocardiogram and/or MRI;

• Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking pomalidomide.)

• Subjects with any condition, including the presence of laboratory abnormalities, which in the opinion of the Investigator places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.

• Subjects with a history of development of erythema nodosum, if characterized by a desquamating rash, while taking thalidomide, lenalidomide, pomalidomide or similar drugs.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of Romidepsin in Combination With Pomalidomide and Dexamethasone	Establish a maximum tolerated dose (MTD) of romidepsin in combination with pomalidomide and dexamethasone in patients with relapsed or refractory multiple myeloma (phase I)	During the duration of the study (from first to last dose of study drug, on average ten 28-day cycles)
Primary	Efficacy of Study Regimen Combination	The efficacy (as assessed by clinical response) of the combination of pomalidomide (CC-4047®) and romidepsin as therapy for patients with relapsed or refractory multiple myeloma (MM) (phase II portion) was evaluated using the IMWG Response Criteria for disease assessment. The best response was reported. (Criteria can be found at the following link, due to length and complexity of the response criteria: http://imwg.myeloma.org/international-myeloma-working-group-imwg-uniform-response-criteria-for-multiple-myeloma/)	From baseline to cycle of maximum response, which occurred on average after 2 cycles; 1 cycle = 28 days
Secondary	Time to Disease Progression (Progression Free Survival)		From start of treatment, to date of disease progression (on average, ten 28-day cycles)
