体液相および糸球体環境における補体調節異常は、腎生検標本にC3補体の沈着をもたらし、C3腎症として知られるまれなカテゴリーの腎臓病を特徴づける。C3腎症の2つの主要なサブグループである濃厚沈着症(DDD)とC3糸球体腎炎(C3GN)は、疾患の連続性の存在を示唆する臨床的・病理学的特徴を有しています。
終末経路の調節障害も頻度が高いが、補体代替経路の調節障害はC3腎症の徴候にとって極めて重要です。大半の患者では、C3またはC5転換酵素を標的とする自己抗体のような後天的要因が疾患を引き起こしています。
IC-MPGNおよびC3Gの経過は、体内の免疫システムの構成要素である補体カスケードの抑制されない活性化によって大きく影響を受けると考えられており、腎臓にC3分解産物が過剰に蓄積すると、炎症と臓器障害が促進されます。C3G患者の約半数は診断から10年以内に末期腎不全になり、その頻度は世界全体で100万人あたり2~3人です。
例えば、2021年6月、ノバルティスは、ファースト・イン・クラスの経口標的B因子阻害薬であるイプタコパン(LNP023)が、C3腎症(C3G)患者の推定糸球体濾過量(eGFR)勾配を改善し、腎機能を安定化させたと報告しました。C3G患者を対象とした非盲検第II相試験(NCT03832114)の中間解析結果によると、イプタコパン1日2回200mgの投与により、血液が腎臓を通過し濾過される速度を示す腎クリアランス機能の重要な指標であるeGFR勾配1が変化し、腎機能が安定しました。
さらに、2022年12月、免疫介在性疾患を治療するための画期的な補体療法を開拓する世界のバイオテクノロジー企業であるキラ・ファーマシューティカルズは、IgA腎症(IgAN)および補体3糸球体症(C3G)を含む腎バスケット試験において、代替補体経路および終末補体経路を選択的に標的とするファーストインクラスの二機能性生物学的製剤であるKP104の評価について、中国国家医薬品監督管理局(NMPA)およびオーストラリア治療品庁(TGA)から第2相試験の開始が承認されたことを報告しました。
C3腎症と呼ばれる稀な腎疾患は、新たな治療法の創出や市場の拡大を困難にしています。患者数が少ないため、製薬会社は希少疾患の研究開発に投資しにくい可能性があります。補体系の根本的な調節障害に対処する標的治療法の創出は困難であるため、市場の潜在的拡大が制約される可能性があります。特に希少疾患の場合、新規治療法の創出には費用と時間がかかります。臨床試験の実施や規制当局のライセンシング取得には多額の費用がかかるため、この分野への投資は抑制される可能性があります。
Complement dysregulation in the fluid phase and in the glomerular milieu, which results in substantial complement C3 deposition in kidney biopsy samples, characterizes the rare category of kidney illnesses known as C3 glomerulopathies. Dense deposit disease (DDD) and C3 glomerulonephritis (C3GN), the two main subgroups of C3 glomerulopathy, have clinical and pathological characteristics that point to the existence of a disease continuum.
Although terminal pathway dysregulation is also frequent, dysregulation of the complement alternative route is crucial to the signs of C3 glomerulopathy. In the majority of patients, acquired factors, such as autoantibodies that target the C3 or C5 convertases, are what cause disease.
The course of IC-MPGN and C3G is thought to be significantly influenced by unchecked activation of the complement cascade, a component of the body's immune system, where excessive buildup of C3 breakdown products in the kidney promotes inflammation and organ damage.1-4 Up to 8,000 people in Europe and 5,000 people in the United States are thought to have IC-MPGN or C3G, and 50% of those patients have renal failure within five to ten years of diagnosis. Around half of persons with C3G have end-stage renal disease within ten years of diagnosis, with a global frequency of 2-3 per million.
For instance, in June 2021, Novartis reported that Iptacopan (LNP023), a first-in-class oral, targeted factor B inhibitor, improved estimated glomerular filtration rate (eGFR) slope and stabilized kidney function in patients with C3 glomerulopathy (C3G). According to the interim analysis results from the open-label Phase II study (NCT03832114) in patients with C3G, twice-daily 200mg of iptacopan stabilized kidney function as indicated by a change in eGFR slope1, a crucial indicator of kidney clearance function that gauges the rate at which blood passes through and is filtered by the kidneys.
In addition, in December 2022, Kira Pharmaceuticals, a global biotechnology company that pioneers transformational complement therapies to treat immune-mediated diseases reported that the Chinese National Medical Products Administration (NMPA) and the Australian Therapeutic Goods Administration (TGA) have approved the start of Phase 2 studies for the evaluation of KP104, a first-in-class bifunctional biologic that selectively targets the alternative and terminal complement pathways, in a renal basket study including IgA nephropathy (IgAN) and complement 3 glomerulopathy (C3G).
A rare kidney condition called C3 glomerulopathy can make it difficult to create new treatments and expand the market. Due to the small patient population, pharmaceutical companies may be less likely to invest in research and development for rare diseases. It has been difficult to create targeted treatments that address the underlying dysregulation of the complement system; hence, the market's potential expansion may be constrained. Creating novel treatments can be expensive and time-consuming, especially for rare disorders. Investment in this field may be discouraged by the significant expenses involved with carrying out clinical trials and obtaining regulatory licenses.
The global C3 glomerulopathy treatment market is segmented based on drug class, route of administration, distribution channel, and region.
Some patients continue to have a high risk of developing progressive CKD even with the best supportive therapy. In addition to conventional therapy, these patients could require immunosuppressive therapy. The therapy also aims to improve hematuria and stabilize renal function. Patients with IgAN are considered to be at high risk of disease development and may be eligible for immunosuppressive medication if they continue to have proteinuria of less than 1 g/day after three to six months of optimal supportive care.
According to BMC Nephrology, in 2023, there are no known treatments for C3G, in contrast to immune-complex mediated MPGN, where treatment focuses on underlying disorders, such as chronic infections, autoimmune diseases, or cancer. In tiny patient cohorts, immunosuppressive therapies such as plasma infusion or plasmapheresis (calcineurin inhibitors, cyclophosphamide, mycophenolate mofetil, or rituximab) have had erratic results.
North America has been a dominant force in the global C3 glomerulopathy treatment market. According to estimates, there are between 0.5 and 3 instances of C3G per million people in the US, with a point prevalence of 14 to 40 cases per million people.1 DDD is typically diagnosed in childhood or early adulthood and seems to be less prevalent than C3GN. Patients typically have proteinuria and hematuria when they first present, which can range from asymptomatic abnormalities in the urine to classic acute glomerulonephritis with kidney failure and hypertension.
For instance, ChemoCentryx, Inc. developed Tavneos and is continuing to do so for the treatment of patients with hidradenitis suppurativ (HS) and C3 Glomerulopathy (C3G). Tavneos has been given orphan medical product classification by Swissmedic for the adjunctive treatment of MPA and GPA (formerly known as Wegener's granulomatosis), two types of ANCA-associated vasculitis, as well as C3G.
The outbreak of the COVID-19 pandemic in late 2019 created unprecedented challenges for industries worldwide, including the global C3 glomerulopathy treatment market. Treatment options for C3 glomerulopathy, an uncommon and complicated kidney condition, have historically been scarce. Immunosuppressive medications are frequently used in conjunction with blood pressure control, proteinuria treatment, and other management strategies.
The complement system-targeting drug eculizumab has showed potential in some patients, but it is not always efficient. In 2021, efforts were made in research and development to find more specialized treatments for C3 glomerulopathy. These initiatives intended to treat the disease's characteristic complement dysregulation, which was at the root of these efforts. Clinical trials for novel therapeutics were ongoing, and their success might increase the range of available treatments.
