Brief 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).

Interventions

DRUGPanobinostat

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.

DRUGSirolimus

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.

DRUGTacrolimus

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.

Inclusion criteria

* Age ≥ 18 years or older at time of enrollment * Signed informed consent * Hematologic disorder requiring allogeneic hematopoietic cell transplantation * Left ventricular ejection fraction (LVEF) ≥ 45% by multiple uptake gated acquisition (MUGA) scan or echocardiogram * Forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and diffusing lung capacity oxygenation (DLCO) adjusted ≥ 50% of predicted values on pulmonary function tests * Transaminases (AST, ALT) \< 3 times upper limit of normal (ULN) values * Creatinine clearance calculated ≥ 50 mL/min * Karnofsky Performance Status Score ≥ 60%. * Human leukocyte antigen (HLA) matched 8/8 (A, B, C, DRB1) related or unrelated donor

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.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants Stratified by Acute Graft Versus Host Disease GVHD Stage100 days post transplantCumulative 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.

MeasureTime frameDescription
Time to Stable Engraftment100 days post transplantStable 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.
Number of Participants With Primary Disease Relapse1 yearIncidence of primary disease relapse and non-relapse related death will be reported per standard definitions. These will be treated as competing risk events.

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.
Percentage of Participants With Overall Survival (OS)1 yearOverall 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.
Percentage of Participants With Relapse-free Survival (RFS)1 yearRelapse-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.
