Phase I of Histone Deacetylase (HDAC) Inhibitor Panobinostat With Ipilimumab With Unresectable III/IV Melanoma

A Phase 1 Study of HDAC Inhibitor Panobinostat (LBH 589) Administered in Combination With Ipilimumab in Subjects With Unresectable Stage III or Stage IV Melanoma

The purpose of this study is to find out if an investigational drug called panobinostat can be given safely with another drug called ipilimumab. Investigators want to learn more about the side effects of this combination of drugs using different doses of panobinostat and the same dose of ipilimumab.

• 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
• Women who are pregnant or breastfeeding
• Women with a positive pregnancy test on enrollment or prior to investigational product administration
• Sexually active fertile men not using effective birth control if their partners are WOCBP
• Exposure to any investigational drug within 4 weeks of study drug administration.
• Any anti-cancer therapy (e.g., chemotherapy, biologics, radiotherapy, or hormonal treatment) within 4 weeks or at least 5 half-lives (whichever is longer) of study drug administration
• Prior therapy with an anti-CTLA4 antibody or an HDAC inhibitor
• Concurrent chemotherapy, hormonal therapy, immunotherapy regimens, or radiation therapy, standard or investigational
• Prisoners or subjects who are involuntarily incarcerated
• Subjects who are compulsorily detained for treatment of either a psychiatric or physical (e.g., infectious disease) illness

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Dose Escalation; Dose Escalation of Panobinostat + Ipilimumab. Participants will be assigned to receive a certain dose of panobinostat (5, 10, 15, or 20 mg) along with a dose of ipilimumab of 3 mg per kg (mg/kg) of body weight.	Drug: Panobinostat; Participants will be assigned to receive a certain dose of panobinostat (5, 10, 15, or 20 mg). The dose of panobinostat will depend on the time point the participant enters the study and the side effects of other participants already on the study.; Other Names: LBH 589; Drug: Ipilimumab; Dose of ipilimumab of 3 mg per kg (mg/kg) of body weight.; Other Names: BMS-734016

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Tolerated Dose (MTD)	MTD and recommended Phase 2 dose (RP2D) of panobinostat (PAN), administered in combination with ipilimumab (IPI) in participants with unresectable Stage III or Stage IV melanoma. The goal is to enroll up to 36 patients for determination of the MTD, but will be successfully concluded earlier if 12 patients are accrued at the dose determined to be the MTD, with 3 dose limiting toxicities (DLTs). All participants who receive study any drug therapy will be evaluated for safety. Safety assessments will be based on medical review of adverse event reports and the results of vital sign measurements, physical examinations, and clinical laboratory tests. Triplicate 12-lead electrocardiograms (ECGs) will be collected prior to dosing on Day 1 of induction cycle 1. MTD of PAN in milligrams (mg), with IPI at 3 mg/kg.	Up to 36 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Immune Related Overall Response Rate (ORR)	Tumor response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and immune-related Response Criteria (irRC). RECIST: Best overall response from start of treatment until disease progression/recurrence. Immune-related Complete Response (irCR): Complete disappearance of all tumor lesions for at least 4 weeks from date of documentation of irCR. Immune-related Partial Response (irPR): Sum of the products of the 2 largest perpendicular diameters of all index lesions, measured and captured as the Sum of Product of Diameters (SPD) baseline. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for Progressive Disease (PD), taking as reference the smallest sum longest diameter (LD) since the treatment started. Immune-related Progressive Disease (irPD): At least a 25% increase in the SPD of all index lesions and new measurable lesions (irSPD) over the nadir SPD calculated for the index lesions.	Up to 36 months
Progression Free Survival (PFS)	Progression Free Survival (PFS): is defined for each participant as the time from first dosing to the first observation of disease progression or death due to any cause. If a subject has not progressed or died at the time of analysis, PFS will be censored on the date of the last disease assessment. PFS will be calculated by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Progressive Disease (PD) = 20% increase in the sum of the longest diameter of target lesions.	Up to 6 months
Overall Survival (OS)	Overall survival: The time from randomization until death from any cause.	36 months
