Study Details

Study Description

Brief Summary

Current data on the impact of donor CHIP on long-term recipient outcome remain largely speculative. Data on the impact of donor CHIP including on allograft function, immunologic dysfunction, graft versus host disease (GVHD), disease relapse and survival across various donor populations are scarce. This is a retrospective-prospective cohort study designed to determine the association between donor gene mutations and outcome following allogeneic HSCT.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: Next generation sequencing

Detailed Description

This is a single centre prospective and retrospective cohort study. This study involves allo-HSCT recipients and their donors at Queen Mary Hospital, Hong Kong. Information on the presence of gene mutations in donor peripheral blood or bone marrow sample; gene mutations in recipient peripheral blood or bone marrow post-allo-HSCT; and donor and recipient outcome will be collected in either prospective, partial-prospective/retrospective or retrospective manner. The information will be used to determine the association between the presence of clonal haematopoiesis in the donor and recipient outcome following allo-HSCT.

Data will be collected through routine clinical visits and/or reviewing medical records. Data will be collected at the time of peripheral blood stem cells (PBSC) or bone marrow stem cells donation, at the time of allo-HSCT, one month post-allo-HSCT and every 6 months thereafter until death/study termination.

Genetic profile of donors will be collected at the time of PBSC or BM stem cell donation. Genetic profile of recipients will be collected at 1-month, 6-month, 12-month post-HSCT and at time of relapse or occurrence of leukaemia.

Gene mutations and pathogenic gene fusion will be determined in the peripheral blood and/or marrow samples by next-generation sequencing (NGS) using a myeloid-gene panel and nanopore long-read sequencing.

Arms and Interventions

Arm Intervention/Treatment
Allogeneic HSCT recipients and donors

Diagnostic Test: Next generation sequencing
Genetic profile of donors will be collected at the time of PBSC or BM stem cell donation. Genetic profile of recipients will be collected at 1-month, 6-month, 12-month post-HSCT and at time of relapse or occurrence of leukaemia. Gene mutations and pathogenic gene fusion will be determined in the peripheral blood and/or marrow samples by next-generation sequencing (NGS) using a myeloid-gene panel and nanopore long-read sequencing.

Outcome Measures

Primary Outcome Measures

  1. Overall survival (OS) of the recipient. [5 years]

    This is defined as the time (in months) from the date of allo-HSCT to death from any cause (event), latest follow-up (censor) or study termination.

  2. Progression-free survival (PFS) of the recipient. [5 years]

    This is defined as the time (in months) from the date of allo-HSCT to relapse/progression (event), death, latest follow-up or study termination.

Secondary Outcome Measures

  1. Acute and chronic GVHD [5 years]

    The occurrence of acute and/or chronic graft-versus-host disease

  2. Leukemia of donor origin [5 years]

    The occurrence of donor cell derived MDS/AML in the recipient following allogeneic HSCT

  3. Cardiac complications [5 years]

    The occurrence of arrthymias, pericardial disease, coronary artery disease, myocardial dysfunction, pulmonary hypertension

  4. Pulmonary complications [5 years]

    The occurrence of bronchiolitis obliterans, bronchiolitis obliterans with organizing pneumonia.
