Exclusion Criteria:

• Active autoimmune disease or a history of known or suspected autoimmune disease with the exception of subjects with isolated vitiligo, treated thyroiditis or resolved childhood asthma/atopy
• Known human immunodeficiency virus (HIV), active hepatitis A, or hepatitis B or C infection
• History of any hepatitis (e.g., alcohol or non-alcohol steatohepatitis (NASH), drug- related, autoimmune)

• Diabetes mellitus uncontrolled by medication
• Known drug or alcohol abuse
• Presence of underlying medical condition that in the opinion of the Investigator or Sponsor could adversely affect the ability of the subject to comply with or tolerate study procedures and/or study therapy, or confound the ability to interpret the tolerability of combined administration of panobinostat and ipilimumab in treated subjects
• History of allergy to components of ipilimumab or panobinostat, or known allergy to other antibody therapies.
• WOCBP who are unwilling or unable to use an acceptable method to minimize the risk of pregnancy for the entire study period and for at least 12 weeks after the last dose of investigational product
