• •Acute myocardial infarction, symptomatic angina pectoris ≤ 6 months prior to starting study drug
• •Presence of congestive heart failure ≥ NYHA class 3
• •QTc \> 480 ms on a screening ECG

• •Presence of permanent cardiac pacemaker
• •Other clinically significant heart disease
• •Subject is taking warfarin at start of treatment or within 6 months prior to start of study treatment.
• •Patient has a concurrent malignancy or has a malignancy within 3 years of study enrollment (with the exception of adequately treated basal or squamous cell carcinoma or nonmelanomatous skin cancer)
• •Patient is concurrently using other approved or investigational antineoplastic agent
• •Patient has received chemotherapy, targeted anticancer therapy, pelvic and/or para-aortic radiotherapy or has had major surgery ≤ 4 weeks (6 weeks for nitrosourea, monoclonal antibodies or mitomycin-C) prior to starting study drug or who have not recovered from side effects of such therapy
• •Patient has impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of mocetinostat (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
• •Patient is currently receiving increasing or chronic treatment (\> 10 days) with corticosteroids or another immunosuppressive agent. The following uses of corticosteroids are permitted: single dose, topical applications (e.g., rash), inhaled sprays (e.g., obstructive airways diseases), eye drops or local injections (e.g., intra-articular).

• •Patient is currently being treated with drugs known to be moderate or strong inhibitors or inducers of isoenzyme CYP3A, and the treatment cannot be discontinued or switched to a different medication prior to starting study drug. Patients must have discontinued strong inducers for at least one week and must have discontinued strong inhibitors before the start of treatment.
• •Note: the oral anti-diabetic drugs troglitazone and pioglitazone are CYP3A inducers.
