蛋白質激酶係催化蛋白質中特定殘基磷酸化的酵素家族,大致上分類為酪胺酸及絲胺酸/蘇胺酸激酶。由於突變、過度表現、或不適當的調控、異常調控(dys-regulation)或去調控(de-regulation)、以及生長因子或細胞激素之過度製造或製造不足所導致之不適當的激酶活性涉及許多疾病,包括但不限於癌症、心血管疾病、過敏、氣喘及其他呼吸道疾病、自體免疫性疾病、發炎性疾病、骨疾病、代謝病症、及神經性病症及神經退化性病症(諸如阿滋海默症(Alzheimer's disease))。不適當的激酶活性觸發各種與涉及前述及相關疾病之細胞生長、細胞分化、細胞功能、存活、凋亡、及細胞遷移性有關的生物細胞反應。
因此,蛋白質激酶已顯示作為用於治療性干預之標靶的重要酵素類別。特別是,細胞蛋白酪胺酸激酶之JAK家族(JAK1、JAK2、JAK3、及Tyk2)在細胞激素訊息傳導上扮演重要角色(Kisseleva et al., Gene, 2002, 285, 1; Yamaoka et al.Genome Biology 2004, 5, 253))。細胞激素在與其受體結合後活化JAK,JAK接著磷酸化細胞激素受體,從而為訊息傳導分子,尤其是最終導致基因表現的訊息傳導子及轉錄活化子(signal transducer and activator of transcription, STAT)家族成員建立停泊位點(docking sites)。已知有許多細胞激素會活化JAK家族。這些細胞激素包括干擾素(interferon, IFN)家族(IFN-α、IFN-β、IFN-ω、限制素(Limitin)、IFN-γ、IL-10、IL-19、IL-20、IL-22)、gp130家族(IL-6、IL-11、OSM、LIF、CNTF、NNT-1/BSF-3、G-CSF、CT-1、瘦素、IL-12、IL-23)、γC家族(IL-2、IL-7、TSLP、IL-9、IL-15、IL-21、IL-4、IL-13)、IL-3家族(IL-3、IL-5、GM-CSF)、單鏈家族(EPO、GH、PRL、TPO)、受體酪胺酸激酶(EGF、PDGF、CSF-1、HGF)、及G蛋白偶聯受體(AT1)。
Tyk2與JAK1配對以介導第I型干擾素(IFN)訊息傳導,而Tyk2與JAK2配對以傳輸介白素(interleukin, IL) IL-12及IL-23訊息傳導。這兩類關鍵細胞激素均涉及發炎性腸道疾病(inflammatory bowel disease, IBD)之病理生理學。Allocca M, et al., Best Practice & Research Clinical Gastroenterology 2018; 32-33; 95-102。由誘導期及維持期的臨床研究結果顯示,以優特克單抗(ustekinumab)(抗IL-12/IL-23受體之p40次單元的單株抗體)或密利基單抗(mirikizumab)(抗IL-23受體之p19次單元的單株抗體)治療,在顯著比例的患有中度至重度疾病活性之潰瘍性結腸炎(UC)個體中誘導並維持臨床緩解(clinical remission)。Sandborn WJ, et al., J Crohn’s and Colitis 2018; 13 (Supp. 1):S024-26; Sandborn WJ, et al., Gastroenterology 2018; 154(6):Supp. 1:S1360-S1361。IL-12及IL-23需要Tyk2進行訊息轉導,提出抑制Tyk2介導之訊息傳導可能有效治療UC的強烈可能性。Floss DM, et al., Mol Biol Cell. 2016; 27(14):2301–16。
化合物(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈係口服上生物可利用之高度選擇性Tyk2抑制劑(Tyk2 inhibitor, Tyk2i)。(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈正在患有斑癬及其他自體免疫性疾病之參與者中進行研究。基於其細胞激素抑制特性,預期(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈藉由抑制Tyk2直接靶向第一型輔助性T細胞(T-helper 1, Th1)、第十七型輔助性T細胞(T-helper 17, Th17)、及第I型IFN訊息傳導途徑。此應該在治療由Th1/Th17及干擾素免疫反應所驅使之發炎性病況中提供治療益處。
在患有中度至重度潰瘍性結腸炎之個體中,有效、安全、及耐受良好的治療需求仍有待解決。UC之標誌性臨床症狀包括與直腸急迫(rectal urgency)及裏急後重相關之出血性下痢(bloody diarrhea)。臨床病程係以惡化及緩解為特徵。UC之診斷係根據臨床懷疑並藉由診斷測試、及排除感染病因來支持。Dignass A, Eliakim R, Magro F, et al., J Crohn's Colitis. 2012; 6(10):965-90)。UC之最嚴重的腸徵象係毒性巨結腸及穿孔。腸外併發症包括關節炎(周邊或軸向受累(involvement))、皮膚病況(結節性紅斑、口瘡口炎、及壞疽性膿皮病(pyoderma gangrenosum))、眼部炎症(眼色素層炎)、肝功能異常(原發性硬化性膽管炎)。患有UC之患者得結腸癌的風險增加,且該風險隨著疾病之持續時間以及受疾病所影響之結腸範圍而增加。Rutter M, Saunders B, Wilkinson K, et al., Gastroenterology, 2004; 126(2):451-9。
UC之醫學治療旨在控制炎症並減輕症狀。可用的醫藥療法有限,總是無法完全減輕發炎性過程,且可能具有顯著的不良作用。輕度至中度活動性UC之療法包括5-胺基柳酸衍生物及免疫抑制劑。本文中所揭示者係發現抑制某些激酶諸如Tyk2的化合物及類似物,且特別是化合物(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈有用於治療UC。因此,本文中所揭示者係減輕人類個體之UC症狀嚴重度的方法,具有更快的起效時間(onset of action)及更低的不良作用發生率。Protein kinases are a family of enzymes that catalyze the phosphorylation of specific residues in proteins, and are roughly classified into tyrosine and serine/threonine kinases. Inappropriate kinase activity caused by mutations, overexpression, or inappropriate regulation, dys-regulation or de-regulation, and overproduction or underproduction of growth factors or cytokines involves many Diseases, including but not limited to cancer, cardiovascular diseases, allergies, asthma and other respiratory diseases, autoimmune diseases, inflammatory diseases, bone diseases, metabolic disorders, and neurological disorders and neurodegenerative disorders (such as Azihai (Alzheimer's disease)). Inappropriate kinase activity triggers various biological cell responses related to cell growth, cell differentiation, cell function, survival, apoptosis, and cell migration related to the aforementioned and related diseases. Therefore, protein kinases have been shown to be an important class of enzymes as targets for therapeutic intervention. In particular, the JAK family of cellular protein tyrosine kinases (JAK1, JAK2, JAK3, and Tyk2) play an important role in cytokine signaling (Kisseleva et al., Gene, 2002, 285, 1; Yamaoka et al. Genome Biology 2004, 5, 253)). Cytokines activate JAK after binding to their receptors. JAK then phosphorylates the cytokine receptors, which are signal transduction molecules, especially signal transducers and activator of transcription (STAT) that ultimately lead to gene expression. Family members establish docking sites. Many cytokines are known to activate the JAK family. These cytokines include interferon (IFN) family (IFN-α, IFN-β, IFN-ω, Limitin), IFN-γ, IL-10, IL-19, IL-20, IL-22 ), gp130 family (IL-6, IL-11, OSM, LIF, CNTF, NNT-1/BSF-3, G-CSF, CT-1, Leptin, IL-12, IL-23), γC family ( IL-2, IL-7, TSLP, IL-9, IL-15, IL-21, IL-4, IL-13), IL-3 family (IL-3, IL-5, GM-CSF), single Chain family (EPO, GH, PRL, TPO), receptor tyrosine kinase (EGF, PDGF, CSF-1, HGF), and G protein coupled receptor (AT1). Tyk2 is paired with JAK1 to mediate type I interferon (IFN) signaling, and Tyk2 is paired with JAK2 to transmit interleukin (IL) IL-12 and IL-23 signaling. Both types of key cell hormones are involved in the pathophysiology of inflammatory bowel disease (IBD). Allocca M, et al., Best Practice & Research Clinical Gastroenterology 2018; 32-33; 95-102. According to the results of clinical studies in the induction and maintenance phases, ustekinumab (a monoclonal antibody against the p40 subunit of IL-12/IL-23 receptor) or mirikizumab (Anti-IL-23 receptor p19 subunit monoclonal antibody) therapy induces and maintains clinical remission in a significant proportion of individuals with ulcerative colitis (UC) with moderate to severe disease activity. Sandborn WJ, et al., J Crohn's and Colitis 2018; 13 (Supp. 1):S024-26; Sandborn WJ, et al., Gastroenterology 2018; 154(6):Supp. 1:S1360-S1361. IL-12 and IL-23 require Tyk2 for signal transduction, which suggests that inhibiting Tyk2-mediated signal transduction may be an effective treatment for UC. Floss DM, et al., Mol Biol Cell. 2016; 27(14):2301-16. Compound (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile is a highly selective and bioavailable Tyk2 inhibitor (Tyk2i) for oral administration. (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile is being studied among participants with tinea rash and other autoimmune diseases. Based on its cytokine inhibitory properties, (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[ 1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile directly targets type 1 helper T cells (T-helper 1, Th1) and type 17 by inhibiting Tyk2 T helper cells (T-helper 17, Th17), and type I IFN signaling pathway. This should provide therapeutic benefit in the treatment of inflammatory conditions driven by Th1/Th17 and interferon immune responses. In individuals with moderate to severe ulcerative colitis, the need for effective, safe, and well-tolerated treatment remains to be resolved. The hallmark clinical symptoms of UC include blood diarrhea associated with rectal urgency and tenesmus. The clinical course is characterized by deterioration and remission. The diagnosis of UC is based on clinical suspicion and is supported by diagnostic tests and excluding the cause of infection. Dignass A, Eliakim R, Magro F, et al., J Crohn's Colitis. 2012; 6(10):965-90). The most serious bowel signs of UC are toxic megacolon and perforation. Extraintestinal complications include arthritis (peripheral or axial involvement), skin conditions (erythema nodosum, aphthous stomatitis, and pyoderma gangrenosum), inflammation of the eye (uveitis) , Abnormal liver function (primary sclerosing cholangitis). Patients with UC have an increased risk of colon cancer, and this risk increases with the duration of the disease and the extent of the colon affected by the disease. Rutter M, Saunders B, Wilkinson K, et al., Gastroenterology, 2004; 126(2):451-9. The medical treatment of UC aims to control inflammation and relieve symptoms. The available medical therapies are limited, always unable to completely reduce the inflammatory process, and may have significant adverse effects. Therapies for mild to moderately active UC include 5-aminosalicylic acid derivatives and immunosuppressive agents. The persons disclosed herein have discovered compounds and analogues that inhibit certain kinases such as Tyk2, and especially the compound (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl) -1H-pyrazol-4-yl)pyrazolo[1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile is useful for the treatment of UC. Therefore, the method disclosed in this article is a method for reducing the severity of UC symptoms in human individuals, which has a faster onset of action and a lower incidence of adverse effects.

實施例1
治療潰瘍性結腸炎之方法
研究係由長達4週的篩檢期、8週的誘導治療期、52週的開放標籤延伸治療期、及4週的安全性追蹤期所組成。在篩檢期之後,將符合資格的參與者以總體2:2:1:1隨機比例隨機分配以接受(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈600 mg(每日一次(QD))、300 mg QD、100 mg QD、或匹配的安慰劑,並基於曾曝露於UC生物治療及在基線時使用口服皮質類固醇進行分層。已完成8週誘導治療而無安全性發現或不符合停藥標準的所有參與者將符合進入52週的開放標籤延伸治療期的資格。符合資格的參與者將接受(1r,3r)-3-(氰基甲基)-3-(4-(6-(1-甲基-1H-吡唑-4-基)吡唑并[1,5-a]吡-4-基)-1H-吡唑-1-基)環丁烷-1-甲腈400 mg QD,且如果有需要,在開放標籤治療期中將劑量逐步降低(de-escalation)至200 mg QD。
實施例2
內視鏡檢
內視鏡檢(大腸鏡檢或可撓式乙狀結腸鏡檢)必須在篩檢期間進行,較佳地在已驗證所有其他合格性標準
(eligibility criteria)之後並在基線前5至7天(不超過10天)內進行,以允許在基線訪視時獲得中心讀取內視鏡檢分項得分,以用於總梅歐得分計算。
中心讀取者(Central Reader)之內視鏡檢分項得分必須在基線訪視時獲得。中心讀取者之評定將用於衍生總梅歐得分以用於研究合格。基於在篩檢期間所進行之日誌數據及內視鏡檢及在基線時所獲得之醫師總體評定(Physician Global Assessment, PGA)的糞便頻率、直腸出血、及中心讀取之內視鏡檢分項得分將用於判定合格。在原始文件中必須有內視鏡檢報告及病理報告。
內視鏡檢亦在第8週與第60週/可能提早中止訪視期間進行,但如果有需要可在現場訪視前最多-7天進行。腸道準備方案(bowel prep)應按當地程序進行。內視鏡之位置將基於在各種插入程度下儀器之長度以及在篩檢內視鏡檢(screening endoscopy)期間所看到之腸的形態特徵。內視鏡檢報告及在過程中所拍攝之任何照片及/或影像記錄應歸檔在參與者的圖表中。
內視鏡檢分項得分將按基於中心讀取者之梅歐得分進行報告,且對於梅歐內視鏡檢分項得分為1,將註明是否存在易脆性(friability)。符合以下2個標準之任一之參與者被認為有結腸直腸癌的風險且必須在隨機分組前進行結腸鏡檢。在原始文件中必須有結腸鏡檢及病理學報告(如果獲得活體組織切片)。
• 如果參與者年齡係≥50歲,則需有在篩檢之10年內的結腸鏡檢以排除腺瘤性息肉。經篩檢內視鏡檢確定患有腺瘤性息肉之參與者將在完成瘜肉切割術(polypectomy)且病理學報告為陰性之後才符合資格。
• 如果參與者已患有廣泛型(即大於左側)結腸炎>8年或疾病局限於結腸之左側(即,結腸脾彎遠端)≥10年,則無論年齡,必須有在篩檢訪視之1年內的結腸鏡檢以檢查發育不良。經活體組織切片確定患有發育不良或癌症之參與者將被排除在外。
實施例3
參與者糞便日誌
研究參與者將使用電子日誌以便在篩檢訪視時開始及在整個研究中在每日基礎上記錄下列訊息:
• 每天糞便之「正常」次數(當沒有發紅(flare)時)。此問題僅會在篩檢訪視時問。
• 在患有UC之前每天糞便之「正常」次數。此問題僅會在篩檢訪視時問。
• 在過去24小時內,個體具有多少次腸蠕動,包括導致下列任一種情況的如廁:具有腸蠕動的同時有血、或黏膜、或糞便。
• 在過去24小時內,當不在廁所卻具有腸蠕動時,個體經歷多少次排泄物、血、黏膜、或液體從肛門之洩漏?
• 糞便中存在血(如果有的話)。
• 糞便中血之描述(如果有的話),僅當註明存在時。
個體總體印象嚴重度(Subject Global Impression of Severity, PGIS)問題將評估過去24小時內你的潰瘍性結腸炎之嚴重度。為了鼓勵一致的日誌記錄,參與者應在篩檢訪視時開始輸入日誌數據並在整個研究中持續下去。在篩檢時將對參與者提供完成日誌的說明並在後續訪視時複查。
實施例4
潰瘍性結腸炎活動性之梅歐得分
梅歐得分係經設計用於量測UC疾病活動性之工具。梅歐得分系統由四個分項得分所組成,每項等級為0至3,且得分越高指示更嚴重的疾病活動性(參見下文及第10.9.3節)。總梅歐得分係所有4個分項得分之彙總,範圍從0至12分。
• 糞便頻率(分項得分0至3)。
• 直腸出血(分項得分0至3)。
• 內視鏡檢發現(分項得分0至3)。
• 醫師總體評定(分項得分0至3)。
計算梅歐得分需要參與者的糞便頻率及糞便中任何血量之評定。梅歐得分將基於參與者最接近研究訪視之最近記錄的3天有效且連續的糞便日誌計算。研究機構(investigator site)將對日誌用法進行訓練,並將訓練參與者使用日誌。由參與者所輸入之日誌數據將在每次訪視時現場複查。
如果缺失糞便日誌數據,則平均值將取自接近研究訪視5天內(且如果是基線訪視,則為之前)所報告之3個最近可用天數以計算梅歐得分。梅歐得分計算的無效日係腸道準備的日期、內視鏡檢的日期、及在內視鏡檢程序之後1天的日期。
若在接近研究訪視5天內(且如果是基線訪視,則為之前)僅報告2個可用有效天數,則除非在5天內沒有報告日誌數據,否則平均值將取自有限可用數據。在此情況下,糞便頻率及直腸出血分項得分將被視為缺失。如果平均值係在>0至<1之間,則直腸出血分項得分將被四捨五入。
實施例5
發炎性腸道疾病調查表(Inflammatory Bowel Disease Questionnaire, IBDQ)
IBDQ係經心理測量學驗證之PRO手段,用於量測患有IBD(包括UC)之參與者的疾病特異性生活品質。IBDQ包含32項,其被分組至4個領域(dimension)中:腸道功能、情緒狀態、全身症狀、及社會功能。4個領域得分如下:
• 腸道症狀:10至70。
• 全身症狀:5至35。
• 情緒功能:12至84。
• 社會功能:5至35。
總IBDQ得分在32至224範圍內。對於總得分及各個領域,較高的得分指示較好的生活品質。至少170之得分對應於臨床緩解且增加至少16分被視為指示臨床有意義之改良。The present invention relates to a method for treating ulcerative colitis in an individual, which comprises administering a compound that inhibits certain JAK such as Tyk2 to an individual in need.

[Chemical synthesis] The compound of the present invention can be prepared by any method known in the art. In particular, the compounds of the present invention can be prepared by referring to the procedures described in their disclosed prior art references. For those compounds that specifically inhibit Tyk2 (including (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazole And [1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile), the preparation method is disclosed in U.S. Patent No. 10,144,738, the content of which is incorporated herein in its entirety . Examples The following non-limiting examples are presented only to illustrate the present invention. Those with ordinary knowledge in the technical field to which the invention pertains will understand that there are many unillustrated equivalents and modifications, but they still form part of the teachings. Example 1 The method study for the treatment of ulcerative colitis consists of a 4-week screening period, an 8-week induction treatment period, a 52-week open-label extension treatment period, and a 4-week safety follow-up period. After the screening period, eligible participants will be randomly assigned to receive (1r,3r)-3-(cyanomethyl)-3-(4-(6- (1-Methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile 600 mg (QD), 300 mg QD, 100 mg QD, or matching placebo, and based on He has been exposed to UC biotherapy and stratified with oral corticosteroids at baseline. All participants who have completed 8 weeks of induction therapy without safety findings or do not meet the discontinuation criteria will be eligible to enter the 52-week open-label extended treatment period. Eligible participants will receive (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1 ,5-a]pyridine 
-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile 400 mg QD, and if necessary, de-escalation to 200 mg QD during the open-label treatment period . Example 2 Endoscopy Endoscopy (colonoscopy or flexible sigmoidoscopy) must be performed during screening, preferably after all other eligibility criteria have been verified and before baseline This should be done within 5 to 7 days (no more than 10 days) to allow the center-reading endoscopy sub-item scores to be obtained at the baseline visit for use in the calculation of the total Mayo score. The scores of the endoscopy sub-items of the Central Reader must be obtained during the baseline visit. The central reader's assessment will be used to derive the total Mayo score for research qualification. Stool frequency, rectal bleeding, and center-reading endoscopy sub-items based on the log data and endoscopy performed during the screening period and the Physician Global Assessment (PGA) obtained at baseline The score will be used to determine the pass. There must be an endoscopy report and a pathology report in the original document. Endoscopy is also carried out in the 8th and 60th week / during the early suspension of the visit, but if necessary, it can be carried out up to -7 days before the on-site visit. Bowel prep should be carried out in accordance with local procedures. The position of the endoscope will be based on the length of the instrument at various insertion levels and the morphological characteristics of the bowel as seen during screening endoscopy. The endoscopy report and any photos and/or video records taken during the process should be filed in the participant’s chart. The score of the endoscopy sub-item will be reported as the Mayo score based on the central reader, and the score of the Mayo endoscopy sub-item is 1, and whether there is friability will be indicated. Participants who meet any of the following 2 criteria are considered at risk of colorectal cancer and must undergo colonoscopy before randomization. The colonoscopy and pathology report must be included in the original file (if biopsy is obtained). • If the participant is ≥50 years of age, a colonoscopy within 10 years of the screening is required to exclude adenomatous polyps. Participants who are determined to have adenomatous polyps by screening endoscopy will not be eligible until they have completed a polypectomy and the pathology report is negative. • If the participant has had extensive (ie greater than the left side) colitis for more than 8 years or the disease is confined to the left side of the colon (ie, the distal splenic curve of the colon) for more than 10 years, regardless of age, they must be in the screening visit Colonoscopy within 1 year to check for dysplasia. Participants confirmed to have dysplasia or cancer through biopsy will be excluded. Example 3 Participants Stool Diary Study participants will use the electronic diary to record the following information at the beginning of the screening visit and on a daily basis throughout the study: • The number of "normal" stools per day (when there is no redness ( flare). This question will only be asked during the screening visit. • The "normal" number of stools per day before suffering from UC. This question will only be asked during the screening visit. • In the past 24 hours, how many bowel movements the individual has, including toileting that resulted in any of the following conditions: blood, mucous membranes, or feces along with bowel movements. • In the past 24 hours, when not in the toilet but with bowel movements, how many times did the individual experience leakage of excrement, blood, mucous membranes, or fluid from the anus? • The presence of blood in the stool (if any). • A description of blood in the stool (if any), only if it is noted as being present. The Subject Global Impression of Severity (PGIS) question will assess the severity of your ulcerative colitis in the past 24 hours. To encourage consistent log records, participants should start entering log data during the screening visit and continue throughout the study. Participants will be provided with instructions for completing the diary during the screening and will be reviewed during follow-up visits. Example 4 The Mayo Score of Ulcerative Colitis Activity The Mayo score is a tool designed to measure UC disease activity. The Mayo scoring system consists of four sub-items, each with a level of 0 to 3, and a higher score indicates more severe disease activity (see below and section 10.9.3). The total Mayo score is the sum of the scores of all 4 sub-items, ranging from 0 to 12 points. • Stool frequency (sub-item score 0 to 3). • Rectal bleeding (sub-item score 0 to 3). • Endoscopy findings (sub-item score 0 to 3). • Physician's overall assessment (sub-item score 0 to 3). The calculation of the Mayo score requires an assessment of the participant’s stool frequency and any blood volume in the stool. The Mayo score will be calculated based on the 3-day valid and continuous stool log of the participant closest to the study visit. The investigator site will train the log usage and train participants to use the log. The log data entered by the participants will be reviewed on-site during each visit. If the stool log data is missing, the average value will be taken from the 3 most recent available days reported within 5 days of the study visit (and if it is the baseline visit, then before) to calculate the Mayo score. The date of the invalid Japanese bowel preparation calculated by the Mayo score, the date of the endoscopy, and the date 1 day after the procedure of the endoscopy. If only 2 available valid days are reported within 5 days of the study visit (and if it is a baseline visit, then before), the average value will be taken from the limited available data unless log data is not reported within 5 days. In this case, stool frequency and rectal bleeding scores will be considered missing. If the average value is between >0 to <1, the rectal bleeding score will be rounded. Example 5 Inflammatory Bowel Disease Questionnaire (IBDQ) IBDQ is a PRO method validated by psychometrics to measure the disease-specific quality of life of participants with IBD (including UC). IBDQ contains 32 items, which are grouped into 4 dimensions: intestinal function, emotional state, systemic symptoms, and social function. The scores in the 4 areas are as follows: • Intestinal symptoms: 10 to 70. • Systemic symptoms: 5 to 35. • Emotional function: 12 to 84. • Social function: 5 to 35. The total IBDQ score ranges from 32 to 224. For the total score and each field, a higher score indicates a better quality of life. A score of at least 170 corresponds to clinical remission and an increase of at least 16 points is considered to indicate a clinically meaningful improvement.
