Vorinostat for Graft-versus-host Disease (GVHD) Prevention in Non-Malignant Adolescent and Young Adults (AYA) Population

Официальное название

Use of Vorinostat as GVHD Prophylaxis in Children, Adolescents, and Young Adults With Non-Malignant Disorders Undergoing Allogeneic Blood and Marrow Transplantation

Обзор

This is a single-arm, open label, phase 2 study to determine the safety and efficacy of vorinostat without serotherapy as GVHD prophylaxis when combined with either tacrolimus and methotrexate or post-transplant cyclophosphamide, tacrolimus, and mycophenolate in patients aged 1 to 26 years of age with non-malignant disorders undergoing bone marrow transplant following myeloablative conditioning.

Подробное описание

The Hypothesis of the trial:

The addition of vorinostat to standard GVHD prophylaxis without serotherapy will lead to improved GVHD-free event-free survival (GEFS) at 1-year post-transplant compared to historical serotherapy-containing GVHD prophylaxis regimens in patients with non-malignant disorders (NMD) undergoing Hematopoietic stem cell transplant (HSCT).

Вмешательства

• Препарат Vorinostat
  For Matched sibling and matched unrelated donor transplant recipients: Vorinostat will be given orally at a dose of 60 milligrams per square meter two times a day (BID) (120 mg/m2/day) from day -10 to day 30 post-transplant. The maximum dose will be 100 mg BID. Haploidentical donor transplant recipients: Vorinostat will be given orally at a dose of 60 mg/m2 BID (120 mg/m2/day) from day +5 (at least 24 hours after completion of the day +4 cyclophosphamide) through day 30 post-transplant.

Критерии участия

Критерии включения

• Non-malignant condition amenable to transplantation, including but not limited to:

• Primary Immunodeficiency/Primary Immune regulatory disorders
• Inborn errors of metabolism
• Red blood cell disorders including hemoglobinopathies per protocol.
• Inherited bone marrow failure syndromes
• Available donor per protocol (matched siblings and matched unrelated donors, haploidentical donors). The use of mismatched unrelated donors will not be allowed for this study.
• Patient and/or legal guardian have signed the informed consent document
• Adequate organ function and performance status for allogeneic hematopoietic stem cell transplantation as defined by institutional practice:

• Pulmonary Function: diffusing capacity of the lungs for carbon monoxide (DLCO), forced expiratory volume in the first second (FEV1), Forced vital capacity (FVC) ≥50% predicted.
• Renal Function: Estimated or actual glomerular filtration rate (GFR) of ≥50 milliliters per minute (mL/min)/1.72 square meter (m2)
• Liver Function: aspartate aminotransferase (AST), alanine aminotransferase (ALT) <3x upper limit of normal; total bilirubin ≤2.5 milligrams per deciliter (mg/dL) unless related to disease or Gilbert syndrome. There is no upper limit for bilirubin in patients with confirmed Gilbert syndrome.
• Cardiac Function: Ejection fraction (EF) ≥50% or fractional shortening (FS) ≥26%
• Performance Status: Karnofsky/Lansky score ≥70%(HIV) and Human T-lymphotropic virus type (HTLV) I/II negative
• Infectious Disease testing: human immunodeficiency virus
• Patients with transfusion-dependent anemias (per protocol) should have a liver MRI to document hepatic iron content (certain values will be excluded)
• All patients of childbearing age must agree to practice 2 effective methods of contraception at the same time or agree to abstinence for 6 months after the last dose for females. Males with female sexual partners of reproductive potential should use contraception during treatment and for at least 3 months after the last dose.
• Patients treated with other investigational therapies for underlying disorder must discontinue these therapies prior to enrollment on the study unless, in the opinion of the treating physician, discontinuing these therapies prior to transplant would place the patient at undue risk of morbidity or mortality. In this case, patients must discontinue investigational therapies prior to initiation of the conditioning regimen.
