Clinical Trial Summary

This study will test PANO in combination with tacrolimus/sirolimus (TAC/SIR) for acute GVHD prevention. The purpose of this study is to determine if Panobinostat (PANO) when used in combination with sirolimus and tacrolimus will help reduce the incidence of Graft-vs-host disease (GVHD).

Exclusion Criteria:

• Active infection not controlled with appropriate antimicrobial therapy

• HIV, hepatitis B (HBcAb positive but HBsAg negative with undetectable viral load are eligible), or hepatitis C infection

• Sorror's co-morbidity factors with total score > 4. Important modification to co-morbidity index calculation: DLCO adjusted will not be included in assessment of pulmonary risk, except those patients with DLCO adjusted < 50% who are excluded from the trial.

• Anti-thymocyte globulin (ATG) as part of the conditioning regimen

• Cyclophosphamide as part of the conditioning regimen or for GVHD prophylaxis

• Pregnancy

• Histone deacetylase (HDAC), DAC, HSP90 inhibitors or valproic acid for the treatment of cancer within 30 days

• Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first PANO treatment

• Impaired cardiac function or clinically significant cardiac diseases, including any one of the following: Any history of ventricular fibrillation or torsade de pointes; Bradycardia defined as heart rate (HR)< 45 bpm (Patients with pacemakers are eligible if HR = 45 bpm); Screening electrocardiogram (ECG) with a QTcF > 480 msec; Right bundle branch block + left anterior hemiblock (bifascicular block); Patients with myocardial infarction or unstable angina = 12 months prior to starting study drug; Other clinically significant heart disease (e.g., New York Heart Association (NYHA) class III or IV , uncontrolled hypertension) as per discretion of principal investigator and/or treating physician; Patients using medications that have a relative risk of prolonging the QT interval or inducing torsade de pointes if treatment cannot be discontinued or switched to a different medication prior to starting study drug with the exception of drugs listed on Appendix B of study documents that are required for hematopoietic cell transplantation (HCT) patients.

Intervention

Drug:
• Panobinostat
Panobinostat (PANO) will begin 5 days (Day -5) before transplant day (Day 0). All participants will take PANO by mouth once a day, three times a week (48 hours apart), every week for 26 weeks (approximately 6 months). PANO will be provided by Novartis as 5-mg pink gelatin capsules.
• Sirolimus
Sirolimus will be given the day before transplant and continued daily for at least one year. SIR will be administered starting on day -1 and thereafter. Dosing will be adjusted to maintain therapeutic targets per Moffitt institutional standards.
• Tacrolimus
Tacrolimus as an infusion or as a pill will begin 3 days before transplant (day -3) and following Moffitt institutional guidelines for dosing. Tacrolimus will be given for at least 50 days and participants will remain on Tacrolimus for as long as it is necessary per standard of care.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Stratified by Acute Graft Versus Host Disease GVHD Stage	Cumulative incidence of acute GVHD grades II-IV by day 100. Investigators will consider =43% incidence of grade II-IV aGVHD not acceptable. Investigators will use 23% incidence rate of GVHD as target. GVHD severity stage and grading and distribution will be measured weekly from day of transplant to day 90 +/- 14 using standard scoring system. Stage of GVHD will be given for each site of involvement (e.g. skin, liver, and gut), as well as a composite score for overall acute GVHD grade. Pathologic confirmation of aGVHD will be dictated by usual clinical practice, and not mandated by this protocol.	100 days post transplant
Secondary	Number of Participants Stratified by Chronic Graft Versus Host Disease (GVHD) Stage	GVHD with onset after 100 days post-HCT with presence of at least one diagnostic manifestation of chronic c-GVHD or distinct manifestation confirmed by biopsy or other relevant tests (e.g., PFT). Classified as: 1- Classic chronic GVHD - meets criteria for chronic GVHD and has no features consistent with aGVHD or 2-Overlap syndrome - features of acute and chronic GVHD exist together. C-GVHD will be measured prospectively in all participants on days 90+/-14 , 120 +/- 14, 150 +/- 14, 180+/- 14, 270+/- 30, and 365 +/- 30 as per standardized scoring system.	100 days post transplant
Secondary	Time to Stable Engraftment	Stable engraftment for white blood count (WBC) is defined as a sustained absolute neutrophil count > 500 over 3 days without cytokine support. Stable platelet engraftments is defined as count of > 20,000 over 7 days without transfusion support. Time to engraftment is defined as time from day 0 to day of sustained engraftment per above criteria for both platelets and WBC.	100 days post transplant
Secondary	Number of Participants With Primary Disease Relapse	Incidence of primary disease relapse and non-relapse related death will be reported per standard definitions. These will be treated as competing risk events.	1 year
Secondary	Number of Participants With Non-relapse Mortality	Incidence of primary disease relapse and non-relapse related death will be reported per standard definitions. These will be treated as competing risk events. Non-relapse death is defined as death in continuous remission from primary disease requiring transplantation.	1 year
Secondary	Percentage of Participants With Overall Survival (OS)	Overall survival: Time from transplant date to death from any cause. Time-to-event data such as overall survival is measured from the date of transplantation. OS will be analyzed using the Kaplan-Meier method.	1 year
Secondary	Percentage of Participants With Relapse-free Survival (RFS)	Relapse-free survival: Time from transplant date to death or primary disease relapse. Time-to-event data such as relapse-free survival is measured from the date of transplantation. RFS will be analyzed using the Kaplan-Meier method.	1 year
