Clinical Trial Summary

To determine the maximum tolerated dose (MTD), if present, and dose schedule of ACY-1215 (ricolinostat) in combination with pomalidomide and low-dose dexamethasone in patients with relapsed-and-refractory multiple myeloma.

Description:

To determine the maximum tolerated dose (MTD), if present, and to identify a recommended dose and schedule of ricolinostat administered in an alternative liquid formulation (ALF) (10mg/mL) in combination with pomalidomide and low-dose dexamethasone in patients with relapsed or relapsed-and-refractory multiple myeloma.

To evaluate the safety and any anti-tumor activity of ricolinostat administered in combination with pomalidomide and dexamethasone as treatment for patients with relapsed or relapsed-and-refractory multiple myeloma, including duration of response.

To assess the Pharmacokinetics and Pharmacodynamics of all three medications administered in combination, and to assess the Pharmacokinetics of ricolinostat and pomalidomide specifically. An evaluation of the relationship between response and biomarkers relating to interacellular acetylation may also be completed.

9. Must have Eastern Cooperative Oncology Group performance status score of 0, 1, or 2.

10. Females of childbearing potential must have a negative serum or urine pregnancy test as described in Appendix 9.3 for the POMALYST REMS™ program. Females of childbearing potential and males must either commit to continued abstinence from heterosexual intercourse or must abide by birth control requirements as described in Appendix 9.3 for the POMALYST REMS™ program.

11. Must agree to refrain from donating blood while on study drug and for 28 days after discontinuation from this study.

12. Must agree not to share study medication with another person.

13. Must be able to take ASA (81 or 325 mg) daily as prophylactic anticoagulation. Patients intolerant to ASA may use low molecular weight heparin. Lovenox is recommended. Coumadin will be allowed provided the patient is fully anticoagulated, with an international normalized ratio of 2 to 3.

Key Exclusion Criteria Includes:

Patients meeting any of the following criteria will be excluded from enrollment in the study:

1. Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the patient from signing the ICF or from following the study requirements.

2. Pregnant or lactating females.

3. Prior therapy with histone deacetylase inhibitor or pomalidomide.

4. Any of the following laboratory abnormalities:

• ANC < 1,000/µL

• Platelet count < 75,000/ µL for patients in whom < 50% of bone marrow nucleated cells are plasma cells, or a platelet count < 50,000 for patients in whom = 50% of bone marrow nucleated cells are plasma cells

• Hemoglobin < 8 g/dL (< 4.9 mmol/L; prior red blood cell transfusion or recombinant human erythropoietin use is permitted).

• 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.

• Serum glutamic oxaloacetic transaminase/aspartate aminotransferase, or serum glutamic pyruvic transaminase/alanine aminotransferase > 3.0 × ULN

• Serum total bilirubin > 2.0 mg/dL

5. Prior history of malignancies, other than MM, unless the patient has been free of the disease for = 3 years. Exceptions include the following:

• Basal or squamous cell carcinoma of the skin

• Ductal carcinoma in situ; or cervical intraepithelial neoplasia

• Carcinoma of the prostate with a current prostate-specific antigen below the upper limit of normal

6. Corrected QT interval (QTc) using Fridericia's formula value > 480 msec at Screening; family or personal history of long QTc syndrome or ventricular arrhythmias including ventricular bigeminy at Screening; previous history of drug-induced QTc prolongation or the need for treatment with medications known or suspected of producing prolonged QTc intervals on electrocardiogram.

7. Known human immunodeficiency virus, hepatitis B virus, and known or suspected active hepatitis C virus infection.

8. Hypersensitivity to thalidomide, lenalidomide, pomalidomide, or dexamethasone (such as Steven Johnson Syndrome). Hypersensitivity, such as rash, that can be medically managed is allowable.

9. Peripheral neuropathy = Grade 2 despite supportive therapy.

10. Radiotherapy or systemic therapy (standard or an investigational or biologic anticancer agent) within 14 days of initiation of study drug treatment.

11. Current enrollment in another clinical trial involving treatment and/or receiving an investigational agent for any reason.

12. Inability or unwillingness to comply with birth control requirements or any of the POMALYST REMS™ requirements per Appendix 9.3.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Determine Maximum Tolerated Dose (MTD) if any, and recommended dose schedule	Identify the MTD of ACY-1215 administered in an alternative liquid formulation (ALF) if present, and identify a recommended dose and schedule. Patients will be followed for completion of 6 28-day Cycles of Study Treatment (for ITT Population analysis).	Every 56 days on treatment, estimated average of 4 months.
Secondary	Safety	To assess the type, frequency, and severity of adverse events (AEs) and relationship of AEs to study drug.	Upon completion of a 28-day treatment cycle and for the duration of treatment, an estimated average of 4 months.
Secondary	Anti-Tumor Activity	Anti-tumor activity will be measured by objective response to treatment as assessed by the site Investigators using International Myeloma Working Group (IMWG) Uniform Response criteria. Anti-tumor activity will also be measured by duration of response, time to response, and time to progression. The Response rate will be the percentage of patients who achieve PR or better. The number of patients who have at least MR or better will also be collected as clinical benefit response. Progression-free survival (PFS) will be defined as the time from first dose of study treatment to the first documentation of disease progression or death from any cause during the study. For responders, time to tumor response and response duration will be analyzed.	Upon completion of a 28-day treatment cycle and for the duration of treatment, an estimated average of 4 months.
Secondary	Pharmacokinetics	Plasma levels of ACY-1215 will be measured to assess the single and multiple dose PK of AC-1215 in combination with pomalidomide and low-dose dexamethasone. Plasma levels of pomalidomide will be measured to assess the PK of pomalidomide in combination with ACY-1215 and low-dose dexamethasone.	Up to 8 days post first dose
Secondary	Pharmacodynamics	Exposure response of ACY-1215 in combination with pomalidomide and low-dose dexamethasone, including biomarkers relating to intracellular protein acetylation, protein levels, mRNA and microRA expression profiles.	Up to 24 hours post first dose
