Clinical Trial Summary

The present project aims at comparing two conditioning regimens (FM-PTCy vs FM-ATG). The hypothesis is that one or the two regimens will lead to a 2-year cGRFS rate improvement from 30% (the cGRFS rate with FM without ATG/PTCy) to 45% (Pick-a-winner phase 2 randomized study).

Description:

This study is a multicenter, randomized, open-label, phase II study pick-a-winner study, comparing 2 conditioning regimens. A total of 114 eligible patients with HLA-matched donors will be randomized 1:1 between the FM-PTCy arm and the FM-ATG arm, with stratification for donor type (related or unrelated). The recruitment period is 3 years with a 5-year follow-up plus a 10-year additional long-term follow-up (for GVHD status, disease status, second malignancy and QOL). The whole study will be completed within 18 years.

Eligibility

Inclusion Criteria:

• Informed consent given by donor or his/her guardian if indicated, as per donor center standard procedures.

Exclusion Criteria:

Patients

• Central Nervous System involvement with disease refractory to intrathecal chemotherapy.

• Terminal organ failure, except for renal failure (dialysis acceptable)

1. Cardiac: Symptomatic coronary artery disease; ejection fraction <40%; uncontrolled arrhythmia, uncontrolled hypertension;

2. Pulmonary: Diffusing Capacity of the Lung for Carbon Monoxide (DLCO)< 40% and/or receiving supplementary continuous oxygen, Forced Expiratory Volume in 1 Second (FEV1)< 40%;

3. Hepatic: Fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin >3 mg/dL, and symptomatic biliary disease;

• Uncontrolled infection;

• Karnofsky Performance Score <70%;

• Patient is a fertile man or woman who is unwilling to use contraceptive techniques during and for 12 months following treatment;

• Patient is a female who is pregnant or breastfeeding;

• Any condition precluding the use of melphalan or Thymoglobulin;

Donors

• Any condition not fulfilling inclusion criteria;

• Unable to undergo leukapheresis because of poor vein access or other reasons.
