Bone Marrow Failure Epidemiology

Key Highlights

• Bone Marrow Failure (BMF) is a condition in which the marrow cannot adequately produce blood cells, leading to single-lineage cytopenia or pancytopenia. It arises from intrinsic stem-cell defects or disturbances in the marrow microenvironment and is broadly classified into Acquired Bone Marrow Failure (ABMF) and Inherited Bone Marrow Failure Syndromes (IBMFS), each with distinct causes and clinical features.
• BMF is diagnosed through blood tests that reveal reductions in red cells, white cells, and platelets, followed by a bone marrow biopsy to document low marrow cellularity and rule out alternative conditions. After establishing the diagnosis, further workups—such as genetic analyses or investigations for potential acquired triggers—are conducted to identify the underlying cause.
• BMF commonly manifests through cytopenia-related symptoms such as fatigue (anemia), recurrent infections (neutropenia), bleeding or easy bruising (thrombocytopenia), and sometimes dyspnea. The timing of onset aligns with etiology: IBMFS typically appear in childhood, while acquired forms—such as aplastic anemia or MDS-related marrow failure—usually present in young adulthood or later life.
• In 2024, the 7MM recorded roughly 35 thousand incident cases of BMF, underscoring the steady clinical burden and the continued need for earlier diagnosis and effective treatment strategies.
• DelveInsight estimates that the United States recorded about 15,600 incident cases of BMF in 2024, underscoring the sustained clinical need in this population.

Bone Marrow Failure (BMF) Understanding

Bone Marrow Failure (BMF) Overview

Bone Marrow Failure (BMF) refers to a condition in which the bone marrow cannot sufficiently generate one or more blood cell lineages, leading to diminished or absent hematopoietic precursors and resulting cytopenias. This impaired hematopoiesis may present as single-lineage deficits or pancytopenia and can arise from intrinsic stem cell abnormalities or disturbances within the marrow microenvironment.

 

Acquired BMF is the most common form in adolescents and adults—arises from immune-mediated injury, toxic exposures, infections, radiation, or clonal disorders and includes aplastic anemia, MDS, and Paroxysmal Nocturnal Hemoglobinuria (PNH), which often overlaps with aplastic anemia. These disorders typically present with fatigue, recurrent infections, and bleeding due to cytopenias. In contrast, inherited BMF syndromes result from germline defects in DNA repair, telomere biology, or ribosomal function and include Fanconi anemia, dyskeratosis congenita, Diamond–Blackfan Anemia (DBA), Shwachman–Diamond syndrome (SDS), Severe Congenital Neutropenia (SCN), and Congenital Amegakaryocytic Thrombocytopenia (CAT), generally presenting in childhood but sometimes diagnosed later because of variable severity.

 

Bone Marrow Failure (BMF) Diagnosis

Evaluation of BMF begins with peripheral smear assessment and bone marrow biopsy to evaluate cellularity, dysplasia, and clonal abnormalities while excluding nutritional deficiencies, infections, toxic exposures, and secondary causes such as PNH. IBMFS are considered when there is early-onset disease, family history, or congenital anomalies. Screening includes chromosome breakage testing for Fanconi anemia, telomere length measurement for dyskeratosis congenita, and genetic sequencing for disorders such as SDS, CAT, DBA, and reticular dysgenesis.

 

Diagnosis of acquired conditions relies on characteristic features: acquired aplastic anemia is defined by pancytopenia with hypocellular marrow; PRCA shows isolated anemia with severe reticulocytopenia; MDS is identified by persistent cytopenias, dysplasia, and clonal cytogenetic or molecular mutations; PNH is confirmed by flow cytometry showing loss of GPI-anchored proteins; and acquired amegakaryocytic thrombocytopenia is diagnosed through isolated thrombocytopenia with markedly reduced megakaryocytes on marrow biopsy.

Bone Marrow Failure (BMF) Epidemiology

For the purpose of designing the patient-based model for BMF, the report provides historical as well as forecasted epidemiology segmented by total BMF cases, incident cases of BMF in the associated indication, and age-specific cases of BMF in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan, from 2020 to 2034.

• In 2024, incident BMF cases in the United States were overwhelmingly concentrated in acquired indications, with 15 thousand cases attributed to acquired BMF, forming the clear majority of the burden. In contrast, inherited BMF indications accounted for nearly 300 incident cases.
• Based on DelveInsight estimates, pediatric patients accounted for around one-third of all BMF cases in the United States in 2024, with adults representing the dominant share at roughly 70%.
• DelveInsight estimates that Japan recorded approximately 4 thousand BMF cases in 2024, highlighting a meaningful clinical burden that underscores the need for improved diagnostic pathways and expanded therapeutic options within this patient population.

KOL Views

To gaze into the epidemiology insights of the real world, we take KOLs and SMEs’ opinions working in the domain through research to fill the data gaps and validate our secondary research on disease incidence.

 

DelveInsight’s analysts connected with 25+ KOLs to gather insights; however, interviews were conducted with 10+ KOLs in the 7MM. Centers such as the University of Minnesota, Newcastle University, Kanazawa University, and others were contacted. Their opinion helps understand and validate current disease incidence, gender involved with the disease, diagnosis rate, and diagnostic criteria.

 

As per the KOLs from the US, HSCT is the main therapy for inherited BMF, with reduced-intensity conditioning and mandatory genetic screening of related donors. DBA is the key exception, often responding to steroids. Supportive care relies on transfusions, infection control, and iron chelation.

 

As per the KOLs from Germany, Telomere Biology Disorders (TBD), caused by germline variants, lead to BMF and multi-organ complications. Even asymptomatic carriers may develop late-onset issues, emphasizing the need for lifelong monitoring and genetic counselling.

 

As per the KOLs from Japan, there is a significant unmet need for safe and effective therapies for aplastic anemia, as some patients show inadequate responses to currently available treatments. ROMIPLATE offers a promising alternative, with the potential to improve outcomes and enable more personalized, patient-tailored treatment strategies for individuals who have not received prior immunosuppressive therapy.
