Aplastic Anemia Life-Course Cohort Study (TRACE-AA)

5. november 2026 opdateret af: Jun Shi, Institute of Hematology & Blood Diseases Hospital, China

A Longitudinal Cohort Study of Aplastic Anemia Across the Disease Course

To establish a longitudinal cohort spanning the entire care continuum of acquired aplastic anemia (AA), from diagnosis and treatment through long-term follow-up, integrating routinely collected clinical data with biospecimens obtained in accordance with applicable ethical and regulatory requirements. The cohort will support observational studies of the natural history of AA; treatment effectiveness and safety; the evolution of clonal hematopoiesis and clonal T-cell populations; immune reconstitution following immunosuppressive therapy (IST); the incidence of platelet transfusion refractoriness and its association with response to IST; and hematopoietic and immune reconstitution after transplantation. Ultimately, the cohort aims to generate real-world evidence to inform clinical practice and reduce the burden of AA.

Studiebefolkning

Patients receiving immunosuppressive therapy, allogeneic hematopoietic stem cell transplantation, or other treatments in routine clinical practice will be enrolled and followed longitudinally from diagnosis through long-term follow-up.

Beskrivelse

Inclusion Criteria:

  • Subjects diagnosed with primary acquired aplastic anemia.
  • Subjects treated at the Institute of Hematology and Blood Diseases Hospital from Jan 1, 2012.

Exclusion Criteria:

  • Subjects that the investigator believes have other reasons that make them unsuitable for inclusion in this study.
  • Subject unlikely to be available for long-term follow-up for any reason (e.g., inability to obtain follow-up data or presence of severe comorbidities).

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
TRACE-AA
  1. Describe real-world treatment patterns and clinical outcomes in AA, including IST, HSCT, and other therapies.
  2. Evaluate treatment-related adverse events and safety, particularly complications of ATG/ALG-based IST and HSCT.
  3. Characterize longitudinal hematopoietic and immune reconstitution after drug therapy or HSCT, including immune-cell subsets, clonal T cells, immune biomarkers, and hematopoietic recovery.
  4. Estimate the cumulative incidence and trajectories of clonal hematopoiesis after IST, including cytogenetic and molecular abnormalities and PNH clones.
  5. Assess prognosis, including treatment discontinuation, relapse, clonal evolution, quality of life, and long-term survival.

Data collected will include: demographic characteristics; medical history and environmental exposures; comorbidities and concomitant medications; medical records; treatment regimens; treatment-related adverse events; treatment outcomes; clonal hematopoiesis and clonal evolution; immune reconstitution; platelet transfusion refractoriness; clonal T-cell populations; quality of life; and health economic outcomes, including healthcare costs and length of hospital stay.

Foranstaltningsbeskrivelse
Tidsramme
Hematologic response
Tidsramme: Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.

Hematologic response contains improvements in hemoglobin level, platelet count and neutrophil count.

Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.
Clonal evolution
Tidsramme: Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.

Progression to paroxysmal nocturnal hemoglobinuria, myelodysplastic syndrome, or acute myeloid leukemia.

Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.
Treatment related adverse events
Tidsramme: Within 10 years after allo-HSCT; within 6 months after IST

The main treatment modalities include allogeneic hematopoietic stem cell transplantation (allo-HSCT) and intensive immunosuppressive therapy (IST). Use Common Terminology Criteria for Adverse Events (CTCAE) Version 6 to assess the adverse event

Within 10 years after allo-HSCT; within 6 months after IST
