非定型溶血性尿毒症症候群(aHUS)は、腎臓の細い血管に異常な血栓が形成される病気です。これらの血栓が血流を制限または遮断すると、溶血性貧血、血小板減少症、腎不全などの重篤な医学的問題を引き起こす可能性があります。aHUSの最も一般的な症状は、錯乱、脳卒中、発作、心臓発作、高血圧、腎臓、心臓、または他の臓器における血栓の形成、吐き気と嘔吐、腹痛、腎障害です。aHUSの診断検査には、赤血球数と血小板数を測定する全血球算定(CBC)検査と、腎機能を調べる血液検査が含まれます。腎臓の健康状態は、クレアチニン値、年齢、性別、人種を用いて計算されるeGFRと呼ばれる検査で測定することができます。
2022年、主要7ヶ国でaHUSと診断された症例は約4,800例でした。主要7ヶ国では、小児患者よりも青年および成人のaHUS症例が多くなっています。2022年には、青年成人は約4,000例、小児患者は約700例でした。aHUSの治療は支持療法であり、急性腎障害と全身合併症の管理に注意を払う。尿毒症、体液過多、電解質異常のある患者には腎代替療法が必要です。血漿交換と補体阻害薬であるエクリズマブが特異的な治療法です。現在、aHUSの治療薬として承認されているのは、エクリズマブとラブリズマブの2剤のみです。
2022年の市場規模は主要7ヶ国の中で米国が最も大きく、調査期間中(2019年~2032年)のCAGRは約4%で2032年までに増加すると予想されます。
薬剤の割高な価格設定により商業的な導入が進んでいないこと、aHUSの治療における安全性への懸念、確定的な診断基準の欠如、今後のジェネリック医薬品競争などがaHUS疾患市場に打撃を与えると予想されます。
主要7ヶ国における非定型溶血性尿毒症症候群(aHUS)の市場規模は、2022年に13億米ドルとなりました。同市場は2032年までに拡大すると予測されています。

Various key players are leading the treatment landscape of aHUS, such as Alexion Pharmaceuticals, Novartis, and Roche. The details of the country-wise and therapy-wise market size have been provided below.
The section dedicated to drugs in the aHUS report provides an in-depth evaluation of late-stage pipeline drugs (Phase III) related to aHUS.
The drug chapters section provides valuable information on various aspects related to clinical trials of aHUS, such as the pharmacological mechanisms of the drugs involved, designations, approval status, patent information, and a comprehensive analysis of the pros and cons associated with each drug. Furthermore, it presents the most recent news updates and press releases on drugs targeting aHUS.
ULTOMIRIS is a medication primarily indicated for the treatment of aHUS. Atypical hemolytic uremic syndrome is a rare and serious condition characterized by the formation of blood clots in small blood vessels throughout the body, leading to damage to vital organs, especially the kidneys. In September 2020, Alexion Pharmaceuticals announced that Japan's MHLW had approved ULTOMIRIS (ravulizumab) for adults and children living with aHUS.
Iptacopan, also known as LNP023, is a first-in-class, orally-administered, small-molecule, potent, and highly selective factor B (FB) inhibitor, a key serine protease of the alternative pathway of the complement cascade. Currently, Iptacopan is in the Phase III development stage. The ongoing Phase III clinical trial is a multicenter, single-arm, open-label trial to evaluate the efficacy and safety of oral, twice-daily LNP023 in adult aHUS patients who are naive to complement inhibitor therapy and is expected to be completed by December 2024.
The introduction of complement C5 inhibition into the treatment landscape has significantly improved patient prognosis and QoL. Currently available complement C5 inhibitors across the 7MM are SOLIRIS (eculizumab) and ULTOMIRIS (ravulizumab), both Alexion Pharmaceuticals products. Alexion Pharmaceuticals was acquired by AstraZeneca in 2021.
The treatment transition of patients being treated with eculizumab to ravulizumab has been established as a viable treatment strategy, as this would lead to a reduction in the dosing frequency, which would then lead to a significant reduction of economic burden (treatment-related costs of repeated infusions) and improve the overall QoL of patients.
Although eculizumab and ravulizumab are safe and effective, their high costs often limit their usage in the treatment landscape. Hence, efficacious pharmacologic options for managing the most prevalent and most disabling stages of aHUS are extremely limited; therefore, new treatments are desperately needed.
In a nutshell, a few potential therapies are being investigated to manage aHUS. Even though it is too soon to comment on the above-mentioned promising candidate to enter the market during the forecast period (2023-2032), it is safe to assume that the future of this market is bright. Eventually, these drugs shall create a significant difference in the landscape of aHUS in the coming years. The treatment space is expected to experience a significant positive shift in the coming years owing to the improvement in healthcare spending worldwide.
aHUS is an extremely rare disease characterized by low levels of circulating red blood cells due to their destruction (hemolytic anemia), low platelet count (thrombocytopenia) due to their consumption, and the inability of the kidneys to process waste products from the blood and excrete them into the urine (acute kidney failure), a condition known as uremia. It is a distinctly different illness from the more common disorder known as a typical hemolytic uremic syndrome, caused by E. coli-producing Shiga toxins (Stx HUS) and is generally foodborne.
Most cases of aHUS are genetic, although some may be acquired due to autoantibodies or for unknown reasons (idiopathic). aHUS may become chronic, and affected individuals may experience repeated episodes of the disorder.
There are two types of HUS: Typical HUS (caused by E. coli or other food/water-borne pathogens) and atypical HUS (usually a genetic mutation but sometimes triggered by other illnesses or unknown causes).
The signs and symptoms of aHUS result from the formation of tiny blood clots (microthrombi) in various small blood vessels. These clots reduce or prevent proper blood flow to various body organs, especially the kidneys. aHUS is a complex disorder, and multiple factors, including certain genetic, environmental, and immunologic factors, all play a role in its development.
Diagnosing aHUS is complicated by the fact that it is more challenging to establish without a family history of the disorder. The diagnostic criteria associated with aHUS are hemolytic anemia (anemia in the presence of broken red blood cells), low platelet count (thrombocytopenia), and kidney dysfunction.
The diagnostic test of aHUS includes a complete blood count (CBC) test, which is used to measure the red blood cell and platelet count, and a blood test to check kidney function. Kidney health can be measured by a test called eGFR which is calculated using the creatinine level, age, sex, and race.
Specific testing is there; both HUS and aHUS share some signs and symptoms with another disease called thrombotic thrombocytopenic purpura (TTP), which has a different underlying cause. Doctors can measure levels of a certain protein in the blood, ADAMTS13, which may help clarify whether a patient has aHUS or TTP.

Treatment of Atypical Hemolytic Uremic Syndrome is supportive, with attention to management of acute kidney injury and systemic complications. The use of packed cells is necessary in patients with severe anemia. Platelet transfusions are rarely required, except in counts are <10 000/cu mm or thrombocytopenia associated with active bleeding or in patients undergoing invasive procedures.
Fluid and electrolyte management is important to maintain intravascular volume status and combat the consequences of aHUS, acute kidney injury, and multisystem organ failure. Electrolyte disturbances should be promptly corrected and nephrotoxic medications avoided. Hypertension should be managed with appropriate agents. Renal replacement therapy is required in patients with uremia, fluid overload, or electrolyte abnormalities. Plasma exchange and eculizumab or rivalizumab, a complement inhibitor, offer specific forms of therapy.
For years, plasma therapy was the standard treatment for individuals with aHUS. Both infusions of fresh frozen plasma (plasma infusion), as well as plasma exchange (plasmapheresis), were utilized. Fresh frozen plasma is a blood derivative that is obtained from donors. Plasma exchange removes potentially harmful substances (e.g., toxins, metabolic substances, and plasma parts) from the blood. Blood is removed from the affected individual, and blood cells are separated from the plasma. The plasma is then replaced with other human plasma, and the blood is transfused into the affected individuals. Plasma exchange can also remove mutant factors and autoantibodies.

The aHUS epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total prevalent cases, diagnosed cases, age-specific cases, and treated cases of aHUS in the United States, EU4 countries (Germany, France, Italy, Spain) and the United Kingdom, and Japan from 2019 to 2032.
To stay abreast of the latest trends in the market, we conduct primary research by seeking the opinions of Key Opinion Leaders (KOLs) and Subject Matter Experts (SMEs) who work in the relevant field. This helps us fill any gaps in data and validate our secondary research.
We have reached out to industry experts to gather insights on various aspects of aHUS, including the evolving treatment landscape, patients' reliance on conventional therapies, their acceptance of therapy switching, drug uptake, and challenges related to accessibility. The experts we contacted included medical/scientific writers, professors, and researchers from prestigious universities in the US, Europe, the UK, and Japan.
Our team of analysts at Delveinsight connected with more than 15 KOLs across the 7MM. We contacted institutions such as the University of Munich, the University of Tokyo, the European Dialysis and Transplant Association, the American Society of Nephrology, etc., among others. By obtaining the opinions of these experts, we gained a better understanding of the current and emerging treatment patterns in the aHUS market, which will assist our clients in analyzing the overall epidemiology and market scenario.
We perform Qualitative and Market Intelligence analysis using various approaches, such as SWOT analysis and Conjoint Analysis. In the SWOT analysis, strengths, weaknesses, opportunities, and threats in terms of disease diagnosis, patient awareness, patient burden, competitive landscape, cost-effectiveness, and geographical accessibility of therapies are provided. These pointers are based on the Analyst's discretion and assessment of the patient burden, cost analysis, and existing and evolving treatment landscape.
Conjoint Analysis analyzes multiple approved and emerging therapies based on relevant attributes such as safety, efficacy, frequency of administration, designation, route of administration, and order of entry. Scoring is given based on these parameters to analyze the effectiveness of therapy.
In efficacy, the trial's primary and secondary outcome measures are evaluated; for instance, in trials for aHUS, one of the most important primary endpoints was achieving hemolysis control, LDH normalization, etc. Based on these, the overall efficacy is evaluated.
Further, the therapies' safety is evaluated wherein the acceptability, tolerability, and adverse events are majorly observed, and it sets a clear understanding of the side effects posed by the drug in the trials. In addition, the scoring is also based on the route of administration, order of entry and designation, probability of success, and the addressable patient pool for each therapy. According to these parameters, the final weightage score and the ranking of the emerging therapies are decided.
Because newly authorized drugs are often expensive, some patients escape receiving proper treatment or use off-label, less expensive prescriptions. Reimbursement plays a critical role in how innovative treatments can enter the market. The cost of the medicine, compared to the benefit it provides to patients who are being treated, sometimes determines whether or not it will be reimbursed. Regulatory status, target population size, the setting of treatment, unmet needs, the number of incremental benefit claims, and prices can all affect market access and reimbursement possibilities.
The report further provides detailed insights on the country-wise accessibility and reimbursement scenarios, cost-effectiveness scenario of approved therapies, programs making accessibility easier and out-of-pocket costs more affordable, insights on patients insured under federal or state government prescription drug programs, etc.
