主要7ヶ国における再生不良性貧血の総発生症例数は、2023年には約2,500例であり、予測期間中に増加すると予測されます。主要7ヶ国Mの中で再生不良性貧血の罹患数が最も多いのは日本であり、2023年には800例でした。推計によると、再生不良性貧血は高齢者に多く、2020年の主要7ヶ国の罹患者数は60歳未満が60%を占め、60歳未満が40%でした。2023年、EU4ヶ国と英国の中で再生不良性貧血症例数が最も多いのはドイツであり、スペインは最下位です。
主要7ヶ国における再生不良性貧血の総市場規模は、2023年に約2億7,000万米ドルとなっており、予測期間中(2024年~2034年)に拡大すると予測されます。米国が約1億9,000万米ドルで最大となっており、EU4ヶ国と英国においては、2023年の市場規模はドイツが最大で、英国は最下位です。治療薬の中では、プロマクタが2034年までに主要7ヶ国で最も高い収益を上げると予想されます。
再生不良性貧血は、初期造血細胞の自己免疫破壊を特徴とする稀で重篤な非悪性疾患です。世界の罹患率は人口100万人当たり年間0.7~7.4人で、欧米に比べアジアでの罹患率が高くなっています。主な治療法は骨髄移植と免疫抑制療法です。最も一般的に使用される免疫抑制剤は、抗胸腺細胞グロブリン(ATG)とシクロスポリンであり、単独または併用で投与されます。40歳以上の患者では、フロントラインISTが一般的な標準治療です。逆に、SAAと診断された小児や若年成人、特にMSDを有する患者に対しては、依然としてBMTが望ましい治療法です。
再生不良性貧血とは、傷害による慢性的な原発性造血不全の症候群を指し、骨髄中の造血前駆体の減少または消失、およびそれに伴う汎血球減少をもたらします。再生不良性貧血の症状は、骨髄が十分な血球を産生できないために起こります。軽度の症状で長年安定している人もいれば、重篤な症状で生命を脅かす合併症にまで進行する人もいます。貧血では、疲れやすい、睡眠不足、脱力感、ふらつき、めまい、神経過敏、頭痛、皮膚の青白さ、呼吸困難、胸痛などの心臓症状がみられることがあります。
再生不良性貧血はまれな疾患であり、他の骨髄不全症候群との重複もあるため、診断に難渋します。出血や感染症に関連する所見を除き、検査では主にリンパ節腫脹がないこと、脾臓や肝臓の腫大がないこと、他の臓器に浸潤がないことなどの陰性所見を示します。再生不良性貧血の診断には、骨髄吸引と生検が不可欠です。細胞遺伝学的異常は、典型的な再生不良性貧血患者の最大12-15%で検出されるため、すべての再生不良性貧血患者に対して系統的な細胞遺伝学的検査が不可欠です。次世代シーケンシング(NGS)を含む分子解析は、疾患の病態生理を理解する上でますます重要となってきています。
当レポートは、主要7ヶ国市場における再生不良性貧血について調査し、過去の疫学と予測、再生不良性貧血市場動向を詳細に紹介しています。また、現在の治療法、新薬、個々の治療法の市場シェア、2020年から2034年までの主要7ヶ国の再生不良性貧血市場規模の現状と予測を提供しています。現在の再生不良性貧血の治療法/アルゴリズムやアンメットメディカルニーズも網羅し、最良の機会を発掘し、市場の可能性を評価します。

Study Period: 2020-2034
Aplastic Anemia Overview
Aplastic anemia refers to the syndrome of chronic primary hematopoietic failure from injury leading to diminished or absent hematopoietic precursors in the bone marrow and attendant pancytopenia. The symptoms of aplastic anemia occur because the bone marrow fails to produce enough blood cells. Some individuals may have mild symptoms that remain stable for many years; others may have serious symptoms that can progress to life-threatening complications. Individuals with anemia may experience tiredness, increased need for sleep, weakness, lightheadedness, dizziness, irritability, headaches, pale skin color, difficulty breathing, and cardiac symptoms like chest pain.
Aplastic Anemia Diagnosis
The rarity of aplastic anemia, coupled with its overlap with other bone marrow failure syndromes, poses a diagnostic challenge.Except for findings related to bleeding or infections, the examination presents mainly negative characteristics: absence of lymphadenopathy, no enlarged spleen or liver, and no infiltration of any other organ. Bone marrow (BM) aspiration and biopsy are essential procedures for diagnosing aplastic anemia. Cytogenetic abnormalities can be detected in up to 12-15% of otherwise typical aplastic anemia patients, making systematic cytogenetic investigations essential for all aplastic anemia patients. Molecular analysis, including next-generation sequencing (NGS), has become increasingly instrumental in comprehending the pathophysiology of diseases.
Aplastic Anemia Treatment
Treatment of aplastic anemia varies, depending upon the individual's age, general health, and the severity of aplastic anemia. Treatment aims to correct the bone marrow failure, as well as to treat the patient's immediate signs and symptoms. The two main forms of specific treatment are bone marrow transplantation and immunosuppressive therapies. Initial treatment of acquired aplastic anemia may be directed toward improving the symptoms that may result from low blood counts. Such treatment consists of giving red blood cell transfusions to correct anemia, platelet transfusions to treat or prevent serious bleeding, and antibiotics to treat or prevent infections. Supportive care is a critical component in the management of aplastic anemia, aiming to address symptoms, complications, and overall patient well-being. Patients often require regular blood transfusions to alleviate anemia and manage low platelet counts.

Marketed Drug
PROMACTA/REVOLADE (eltrombopag): Novartis
PROMACTA/REVOLADE (eltrombopag) tablets contain eltrombopag olamine, a small molecule thrombopoietin (TPO) receptor agonist for oral administration. Eltrombopag, sold under the brand name PROMACTA, among others, is a medication used to treat thrombocytopenia and severe aplastic anemia (SAA). Eltrombopag is sold under the brand name REVOLADE outside the US and is marketed by Novartis. In August 2014, the US FDA approved a sNDA for the once-daily use of PROMACTA in patients with severe aplastic anemia (SAA) who had an insufficient response to immunosuppressive therapy. And later in November 2018, the us FDA expanded the label for PROMACTA (eltrombopag) to include first-line treatment for adults and pediatric patients 2 years and older with SAA in combination with IST.
ROMIPLATE (romiplostim; AMG531): Kyowa Kirin/Amgen
ROMIPLATE is composed of recombinant protein acting on the thrombopoietin receptor, which has been licensed from Amgen (K-A) to Kyowa Kirin. It was launched as a drug for idiopathic thrombocytopenic purpura (ITP) in April 2011 and for aplastic anemia in patients who had an inadequate response to conventional therapy in June 2019 in Japan. The drug is composed of recombinant protein stimulating hematopoiesis via acting on the thrombopoietin receptors. It acts directly on megakaryocytic progenitor cells and exerts platelet hematopoietic effects.
Emerging Drug
REGN7257: Regeneron Pharmaceuticals
REGN7257 is a gc cytokine receptor antibody that targets the common g chain (gc; IL-2RG) found in interleukin (IL) receptors for various gc cytokines, including IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. It was developed to investigate the potential of targeting gc cytokines for the prevention and treatment of T-cell-mediated diseases. By blocking the signaling of gc cytokines, REGN7257 aims to ameliorate T-cell-mediated pathogenesis. The drug REGN7257 is presently undergoing evaluation in a Phase I/II clinical trial to assess its safety and tolerability in patients with severe aplastic anemia (SAA) who have either relapsed after immunosuppressive therapy (IST) or are refractory to IST.
OMISIRGE (omidubicel): Gamida Cell
OMISIRGE (omidubicel-onlv) is a cryopreserved nicotinamide-modified allogeneic hematopoietic progenitor cell therapy derived from cord blood and manufactured utilizing a proprietary NAM-based technology producing enriched HPCs. It is indicated for use in adults and pediatric patients aged 12 years and older with hematologic malignancies who are planned for umbilical cord blood transplantation following myeloablative conditioning. Omisirge has received approval for use in hematological malignancies and is currently undergoing evaluation in an ongoing investigator-sponsored Phase I/II study focusing on patients with severe aplastic anemia.
In real-world scenarios, the approach to treating NSAA differs significantly from SAA/VSAA. Unlike SAA/VSAA, hematopoietic stem cell transplantation (HSCT) is not employed in NSAA cases. The criteria for determining when to initiate treatment for NSAA are less clearly defined, and there is a lack of comprehensive recommendations for clinical evaluation and therapeutic strategies. The ultimate management of NSAA predominantly relies on the expertise of individual medical centers. Historically, the primary modalities for treating aplastic anemia have been IST and BMT in eligible patients. For individuals with SAA/VSAA deemed suitable for transplant-based interventions, age emerges as a pivotal determinant influencing survival post-matched sibling donor (MSD) allogeneic transplantation. Notably, older patients, often having undergone prior IST, presenting with additional comorbidities, diminished performance status, and an extended duration between diagnosis and BMT, exhibit distinctive challenges in outcomes, with fludarabine-containing regimens offering more promising results in this demographic, albeit based on limited retrospective analyses. In the realm of second-line treatments, patients with aplastic anemia are considered eligible for transplantation in cases of refractory status following first-line IST. IST in the form of horse ATG + CyA has been extensively researched regimen in Europe, Asia, and the United States over several decades. Recent endeavors to enhance the efficacy of horse ATG have involved augmenting immunosuppression with agents such as mycophenolate, sirolimus, rabbit ATG, alemtuzumab, and cyclophosphamide.
Approximately a decade ago, notable progress was made with the approval of thrombopoietin receptor agonists for immune thrombocytopenia, effectively inducing platelet count recovery in refractory cases. Distinguishing itself from erythropoietin and G-CSF, the Tpo receptor is expressed in stem cells. Tpo receptor knockout models revealed significant reductions not only in megakaryocytes and platelets but also in HSCs. In 2014, the US FDA approved PROMACTA for the treatment of aplastic anemia, which then approved in Europe and Japan in 2015 and 2017, respectively, under the brand name REVOLADE. Later, another Tpo receptor agonist, ROMIPLATE, was granted approval in Japan in June 2019 for aplastic anemia cases where conventional treatments have proven insufficient.
With respect to the emerging pipeline, there is a scarcity of advancements in SAA treatment, with only two companies in the 7MM actively engaged in developing therapies-Regeneron Pharmaceuticals with REGN7257 and Gamida Cell with omidubicel. This underscores the crucial need for additional research and development to broaden the spectrum of treatment options for this complex condition.
