A Phase IV Clinical Study of Evaluating the Safety and Efficacy of Icatibant Injection (Icanticure) in the Treatment of Patients With Bradykinin Induced Angioedema

This is a phase IV clinical study. The investigators collect patients with a diagnosis of bradykinin induced angioedema. For a specific study period and prospectively arrange, the eligible patients who has an acute attack of angioedema could be treated by icatibant Injection (Icanticure®).
The drug, icatibant injection has been reimbursed by National Health Insurance Agency, Taiwan (NHI) in the treatment of diagnosed patients with hereditary angioedema. However, the reimbursement is still limited for some patients with atypical conditions. Therefore, Nang Kuang Company initiates a phase IV case collection study and supplies Icanticure® for free during the study period. Patients who still unable to obtain NHI's reimbursed icatibant drug is eligible for the inclusion, enter into the study and can be treated by Icanticure® to meet their clinical urgent needs. The safety and efficacy of Icanticure® are evaluated by the prospective, planed assessments in the enrolled patients.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) disrupts multiple host regulatory systems, including the kallikrein-kinin system (KKS), which plays a central role in vascular homeostasis and inflammation. Following viral entry, angiotensin-converting enzyme 2 (ACE2) is internalized and inactivated, impairing the degradation of des-Arg⁹-bradykinin (DABK), a selective agonist of the inducible kinin B1 receptor (B1R), while inflammatory feedback mechanisms may further elevate bradykinin (BK), the kinin B2 receptor (B2R) agonist. It has been postulated that the kinin storm observed in COVID-19 patients may lead to pulmonary angioedema, promote the exacerbated production of pro-inflammatory cytokines, and be related to disease progression, permanent sequelae, and death. However, it remains unknown whether in vitro SARS-CoV-2 infection triggers alterations in the KKS and its downstream inflammatory and vasoactive mediators. Here, we investigated how SARS-CoV-2 infection modulates kinin signaling and its downstream inflammatory and vasoactive mediators in Vero E6 and human endothelial (HUVEC) cells. SARS-CoV-2 infection increased BK levels and markedly upregulated B1R gene expression in Vero E6 cells (up to 20-fold), while B2R expression remained unchanged. Both BK and DABK reduced ACE2 expression in Vero E6 cells, an effect most likely mediated by DABK-B1R signaling due to the minimal expression of B2R in this cell line. Viral infection induced robust production of nitric oxide (NO) and interleukin-6 (IL-6) in Vero E6 cells, and supernatants from infected cells triggered similar responses in HUVECs. Pharmacological blockade of B1R with R-715 selectively prevented SARS-CoV-2-induced NO production in Vero E6 cells, whereas IL-6 induction occurred through B1R-independent mechanisms. In contrast, in endothelial HUVEC cells exposed to serum from patients with severe COVID-19, B2R antagonism with HOE-140 prevented both NO and IL-6 production, suggesting a key role for B2R in both vascular cytokine amplification and vasoactive mediator production. Our findings reveal a compartment-specific and complementary activation of B1R and B2R during SARS-CoV-2 infection, establishing the KKS as a key mediator of endothelial alterations and inflammatory amplification in COVID-19 and positioning B1R and B2R as therapeutic targets.

Angioedema reported with tissue plasminogen activators: A need to communicate on bradykinin- and histamine-mediated mechanisms

Article

作者: Polard, Elisabeth ; Largeau, Bérenger ; Gautier, Sophie ; Beau-Salinas, Frédérique ; Maurier, Anaïs ; Jonville-Bera, Annie-Pierre

AIM OF THE STUDY:

Angioedema (AE) is a potentially life-threatening adverse effect. The mechanism can be either bradykinin- (BK-AE) or histamine-mediated (Hi-AE), each requiring different management. AE are reported with recombinant tissue plasminogen activators (alteplase and tenecteplase), for which an immunoallergic or bradykinic mechanism is suggested. The aim of this study was to describe the characteristics of cases of AE (BK or Hi) reported with rt-PA to the French Regional Pharmacovigilance Centers in order to optimize their identification and management.

METHODS:

All cases of AE reported with alteplase or tenecteplase until 30 November, 2023 were analyzed and classified as Hi-AE or BK-AE using the clinical manifestations, the management and the allergological workup.

RESULTS:

We analyzed 151 cases of AE, with a median time to onset of 1h (IQR=1-2h), all localized at the head. From them, 150 were with alteplase use for acute ischemic stroke (98%) or myocardial infarction (2%), and 1 with tenecteplase. Of them 107 (71%) could be clearly categorized and were classified as 98 (92%) cases of BK-AE and 9 (8%) cases of Hi-AE. When the use of icatibant or C1 esterase inhibitor is specified, it was the 1st-line treatment for 32/47 (68%) patients.

CONCLUSION:

The majority of cases of AE reported with rt-PA, are BK-AE involving alteplase. This is consistent with the effects of rt-PA, which activates the kinin pathway by hydrolyzing plasminogen to plasmin, resulting in the formation of bradykinin. Clinicians need to be informed of this mechanism, in order to early prescribe the appropriate treatment, as we detect that it was not systematically used as 1st-line therapy for a lot of cases.

Article

作者: Zheng, Danping ; Ma, Haiyuan ; Huang, Zhoulin ; Chen, Baili ; Xiong, Shanshan ; Mao, Ren ; Tian, Chunyang ; Wang, Yangdi ; Li, Xuehua ; Ke, Yangyang ; He, Yao ; Chen, Minhu

Background:

Hereditary angioedema (HAE) is a rare, severe, disabling, and life-threatening disorder characterized by recurrent and unpredictable edema of skin and mucous membranes. Gastrointestinal edema, often presenting as abdominal pain, is common but frequently misdiagnosed, leading to unnecessary surgeries. This study aims to characterize gastrointestinal edema in HAE patients to improve early diagnosis and guide treatment.

Method:

We analyzed 61 patients with HAE who were admitted in our hospital between April 1, 2023 and August 31, 2025. Data on demographic characteristics, clinical manifestations, laboratory findings, imaging results, and treatment outcomes were collected through questionnaires and hospital electronic records.

Result:

Among the patients, 86.9% experienced gastrointestinal edema, mostly characterized by abdominal pain (94.3%), nausea (79.2%), and diarrhea (71.7%). Misdiagnosis occurred in 73.6% of cases, and 22.6% underwent unnecessary surgeries. The median age of gastrointestinal edema onset was 16.0 years, with the most severe episodes occurring at a median age of 25.0 years. The median annual frequency of attacks was 4.0/year, with a median severity score of 7.0. Acute attacks showed elevated D-dimer, white blood cells, neutrophils, and hemoglobin. CT imaging frequently revealed intestinal wall thickening and abdominal-pelvic effusion. Lanadelumab demonstrated superior efficacy over danazol in reducing both the frequency and severity of edema attacks, while icatibant significantly shortened the duration of edema episodes.

Conclusion:

This study updates the clinical and imaging features of gastrointestinal edema in Chinese patients with HAE, identifies biomarkers of gastrointestinal edema attacks, and highlights the efficacy of lanadelumab and icatibant, aiding timely diagnosis and treatment.

Evidence of Efficacy and Safety of Deucrictibant for Prophylaxis and On-Demand Treatment of Hereditary Angioedema Attacks Published Back-to-Back in The Lancet Haematology

Results from Phase 2 clinical studies, CHAPTER-1 and RAPIDe-1, provide evidence of viability of bradykinin B2 receptor antagonism in management of HAE ZUG, Switzerland, March 20, 2026 (GLOBE NEWSWIRE) -- Pharvaris (Nasdaq: PHVS), a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to help address unmet needs of those living with bradykinin-mediated diseases such as hereditary angioedema (HAE) and acquired angioedema due to C1 inhibitor deficiency (AAE-C1INH), today announced that two articles have been published back-to-back in the same issue of The Lancet Haematology. The articles detail data from the two randomized Phase 2 studies, CHAPTER-1 and RAPIDe-1 , evaluating the efficacy and safety of deucrictibant, a potent, orally bioavailable small-molecule bradykinin B2 receptor antagonist, in development for the prophylaxis and on-demand treatment of HAE attacks, respectively. “Since HAE is a bradykinin-mediated disease, regulation of bradykinin signaling through B2 receptor antagonism could both prevent HAE attacks and manage angioedema symptoms when they occur,” said Marc A. Riedl, M.D., M.S., Professor of Medicine, Clinical Director of the U.S. Hereditary Angioedema Association (HAEA) Angioedema Center at the University of California San Diego (UCSD), and investigator in both studies. “The statistically significant, placebo-controlled data from these two distinct clinical studies provide important evidence that deucrictibant, a bradykinin B2 receptor antagonist, may offer a viable option for both prophylactic and acute treatment of HAE attacks. Based on these results, deucrictibant is emerging as a potentially unique oral therapy for HAE, providing on-demand and preventative treatment effects through the availability of both the immediate-release capsule and extended-release tablet. This complementary approach may further improve HAE management for patients and prescribers alike.” CHAPTER-1 Study Results CHAPTER-1, a double-blind, placebo-controlled Phase 2 proof-of-concept study of deucrictibant for the prophylactic treatment of HAE attacks, demonstrated statistically significant reduction in the occurrence of attacks and clinically meaningful improvements in disease control and health-related quality of life. Deucrictibant was well tolerated at both doses tested. RAPIDe-1 Study Results RAPIDe-1, a double-blind, placebo-controlled Phase 2 study of deucrictibant immediate-release capsule for the on-demand treatment of HAE attacks, demonstrated a statistically significant reduction in severity of attack manifestations, as well as a reduced time to symptom relief and resolution. Deucrictibant was well tolerated at all doses tested. Peng Lu, M.D., Ph.D., Chief Medical Officer of Pharvaris, stated, “icatibant use has established bradykinin B2 receptor antagonism as the standard-of-care approach for on-demand treatment of HAE attacks. The RAPIDe-1 data are the first-ever clinical study data supporting deucrictibant as an oral on-demand therapy, and the CHAPTER-1 data are the first-ever clinical study data supporting bradykinin B2 receptor antagonism as an effective approach for prophylaxis of HAE attacks. Upon regulatory approval for both indications, deucrictibant could offer an end-to-end portfolio of options for bradykinin-mediated angioedema care. The two articles, published concurrently in The Lancet Haematology , add to the scientific evidence to further advance understanding of bradykinin-mediated angioedema and eventually inform clinical decisions about management in real-world clinical practice.” Topline data from CHAPTER-3 ( NCT06669754 ), an ongoing Phase 3 clinical study evaluating deucrictibant extended-release tablet for the prophylactic treatment of HAE attacks, is anticipated in the third quarter of 2026. Topline data from RAPIDe-3 ( NCT06343779 ), a pivotal, placebo-controlled Phase 3 clinical study evaluating deucrictibant immediate-release capsule for the on-demand treatment of HAE attacks, demonstrated that treatment with deucrictibant resulted in faster symptom relief and complete symptom resolution of HAE attacks and in most attacks being treated with a single capsule. These confirmatory data of deucrictibant’s potential as an oral on-demand treatment were presented at the American Academy of Allergy, Asthma & Immunology (AAAAI) 2026 Annual Meeting . The full articles can be found here: Oral deucrictibant for prophylaxis of hereditary angioedema attacks (CHAPTER-1): primary analysis of a randomised, double-blind, placebo-controlled, phase 2 trial Oral deucrictibant for on-demand treatment of hereditary angioedema attacks (RAPIDe-1): a randomised, double-blind, placebo-controlled, phase 2 trial About Deucrictibant Deucrictibant is a novel, potent, orally bioavailable small-molecule bradykinin B2 receptor antagonist currently in clinical development. Deucrictibant is being investigated for its potential to prevent the occurrence of bradykinin-mediated angioedema attacks and to treat the manifestations of attacks if/when they occur by inhibiting bradykinin signaling through the bradykinin B2 receptor. Pharvaris is developing two formulations of deucrictibant for oral administration: an extended-release tablet to enable sustained absorption and efficacy as prophylactic treatment, and an immediate-release capsule to enable rapid onset of activity for on-demand treatment. Deucrictibant has been granted orphan drug designation for the treatment of bradykinin-mediated angioedema by the U.S. Food and Drug Administration, the European Commission, and Swissmedic. About Pharvaris Pharvaris is a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to help address unmet needs in bradykinin-mediated conditions, including all types of bradykinin-mediated angioedema. Pharvaris’ aspiration is to offer therapies with injectable-like efficacy™, a well-tolerated profile, and the convenience of oral administration to prevent and treat bradykinin-mediated angioedema attacks. By delivering on this aspiration, Pharvaris aims to provide a new standard of care in bradykinin-mediated angioedema. Pharvaris is preparing marketing authorization applications for deucrictibant immediate-release capsule as an on-demand treatment of HAE attacks, and a global pivotal Phase 3 study of deucrictibant extended-release tablet for the prevention of HAE attacks (CHAPTER-3) is ongoing with topline data anticipated in the third quarter of 2026. In addition, CREAATE is an ongoing Phase 3 study of deucrictibant for the prophylactic and on-demand treatment of AAE-C1INH attacks. For more information, visit .

Septerna Highlights Pipeline Progress and Reports Fourth Quarter and Full Year 2025 Financial Results

Compelling Phase 1 Data for SEP-631 (MRGPRX2 NAM) in Healthy Volunteers Support Phase 2b Development, Initially in Chronic Spontaneous Urticaria (CSU) in Second Half of 2026 Advancing SEP-479 (PTH1R Agonist) Toward Phase 1 Initiation in First Half of 2026 Cash Runway Expected to Support Operating Plans at Least into 2029 SOUTH SAN FRANCISCO, Calif., March 09, 2026 (GLOBE NEWSWIRE) -- Septerna, Inc. (Nasdaq: SEPN), a clinical-stage biotechnology company pioneering a new era of G protein-coupled receptor (GPCR) drug discovery, today highlighted pipeline progress and anticipated milestones and reported financial results for the fourth quarter and full year ended December 31, 2025. "We made significant strides advancing our pipeline in the past year, and 2026 has already delivered a meaningful milestone with positive Phase 1 results for SEP-631,” said Jeffrey Finer, M.D., Ph.D., chief executive officer and co-founder of Septerna. “These results demonstrate clinical proof-of-mechanism and validate the ability of our Native Complex Platform ® to uncover novel mechanisms of action and rapidly generate differentiated oral small molecules for historically challenging GPCRs. With SEP-479 approaching Phase 1 initiation in the coming months, SEP-631 poised for Phase 2 development in the second half of the year, and additional programs progressing behind them, we believe 2026 will be a year of strong progress for Septerna and for the patients we are committed to serving.” Recent Pipeline Progress and Anticipated Milestones SEP-631 MRGPRX2 NAM for Mast Cell Diseases: In March 2026, Septerna presented positive results from its Phase 1 clinical trial evaluating SEP-631, its potent, selective and insurmountable oral small molecule MRGPRX2 negative allosteric modulator (NAM) and outlined its initial Phase 2 development strategy. Key findings include: Safety: SEP-631 was well-tolerated at all doses studied with an adverse event pro to placebo. Pharmacokinetics (PK): SEP-631 demonstrated a PK pro of convenient once-daily oral dosing without food restrictions. Pharmacodynamics (PD): SEP-631 produced robust suppression of wheal formation across evaluated dose levels, with complete inhibition observed at doses as low as 10 mg once daily following the 10 µg/mL icatibant challenge. Following the 100 µg/mL icatibant challenge, inhibition was dose-dependent, with progressively greater suppression observed at increasing SEP-631 doses with near to complete inhibition achieved at 90 and 200 mg once daily. Septerna plans to initiate a Phase 2b trial of SEP-631 in CSU in the second half of 2026 following completion of long-term toxicology studies, with an open-label study in chronic inducible urticaria (CIndU) patients with symptomatic dermatographism to follow. Septerna is also evaluating additional mast cell-driven diseases with high unmet need and MRGPRX2 expression on tissue-resident mast cells. SEP-479 PTH1R Agonist for Hypoparathyroidism: Septerna has completed IND-enabling studies for SEP-479, its potent and selective oral small molecule PTH1R agonist, and is on track to initiate a Phase 1 clinical trial in the first half of 2026. TSHR NAM Program: Septerna continues to progress toward development candidate selection for its TSHR NAM program, with the goal of delivering a potential disease-modifying oral treatment for Graves’ disease and thyroid eye disease.

一、开场介绍会议时间：2026年第四季度主持人说明：会议为第46届年度TDCowan医疗健康大会的一部分，由TDCowan生物技术分析师YaronWerber主持，目的是介绍Septerna公司最新研发进展。管理层发言摘要：JeffFiner（首席执行官）：Septerna是专注于GPCR药物发现的公司，核心技术为“天然复合物平台”（NativeComplexPlatform），旨在解锁传统难以成药的GPCR靶点；公司管线聚焦验证靶点，注重早期临床读数，目前现金储备可支持至2029年；重点介绍SEP-631（MRGPRX2负变构调节剂）和SEP-479（PTH激动剂）项目进展。二、财务业绩分析核心财务数据：暂无信息关键驱动因素：暂无信息三、业务运营情况研发投入与成果SEP-631（MRGPRX2负变构调节剂）：I期临床数据显示，单剂量10-400mg及多剂量10-200mg耐受性良好，无严重不良事件；皮肤激发试验中，10mg剂量即可完全抑制低剂量艾替班特诱导的风团，90-200mg可抑制高剂量艾替班特诱导的风团，药代动力学半衰期约24小时，支持每日一次口服给药。SEP-479（PTH激动剂）：临床前研究显示其为选择性小分子激动剂，可使甲状旁腺功能减退症大鼠模型血清钙正常化；猴子PK-PD研究显示内源性PTH水平显著降低（约80%），钙水平呈剂量依赖性增加；IND支持研究基本完成，计划未来几个月进入临床。合作项目：与诺和诺德关于肠促胰岛素受体及其他靶点的临床前合作进展顺利。平台技术：“天然复合物平台”已验证可发现新型GPCR调节剂，如SEP-631的不可克服负变构调节机制（结合跨膜域隐蔽口袋，阻断激动剂结合）。四、未来展望及规划短期目标（2026年及近期）SEP-631：计划2026年下半年启动II期慢性自发性荨麻疹（CSU）临床试验，设计为12周研究（含剂量探索+安慰剂对照），可能后续开展开放标签扩展。SEP-479：IND支持研究完成，计划在澳大利亚启动I期临床试验，评估单剂量递增和多剂量递增（7-10天）的安全性及药效。中长期战略适应症拓展：SEP-631除CSU外，计划评估特应性皮炎、间质性膀胱炎、偏头痛、哮喘等潜在适应症；SEP-479聚焦甲状旁腺功能减退症，探索长期钙控制方案。管线推进：持续推进TSH受体项目及早期阶段研发项目，依托“天然复合物平台”拓展GPCR靶点覆盖。五、问答环节要点SEP-631II期试验设计问：II期试验周期及设计？答：计划为12周研究，含3-4个药物剂量水平+安慰剂对照，可能后续开展开放标签长期扩展。SEP-631安全性与毒性研究问：慢性给药的毒性覆盖情况？答：已完成28天毒性研究支持I期；启动II期前将完成6个月大鼠、9个月狗慢性毒性研究，预计2026年年中获得数据，降低项目风险。MRGPRX2与IgE途径的关系问：X2介导疾病是否独立于IgE，是否需联合抑制？答：CSU等疾病可能存在混合机制，部分患者对IgE疗法无反应；X2抑制剂可能通过阻断肥大细胞脱颗粒反馈循环，对IgE高/低患者均有效，即使初始触发为IgE途径。SEP-479I期剂量设计问：I期剂量范围研究方案？答：从低剂量开始单剂量递增，避免健康志愿者血钙过高；基于半衰期（预计40-80小时）进行多剂量递增（7-10天），监测内源性PTH降低及钙水平变化。SEP-479滴定方案问：参考Yorvipath的复杂滴定方案，SEP-479如何设计？答：需根据半衰期确定，若与Yorvipath（60小时）接近，可能采用相似滴定频率；目标是通过剂量调整实现钙和维生素D补充剂独立，避免高/低钙血症。六、总结发言管理层表示：Septerna将持续依托“天然复合物平台”推进GPCR药物研发，重点推进SEP-631和SEP-479临床进展；SEP-631的I期数据验证了平台技术转化能力，有望成为同类最佳MRGPRX2拮抗剂；SEP-479为甲状旁腺功能减退症提供口服治疗新选择；未来将拓展多适应症并深化合作，推动管线价值最大化。查看业绩会议全文
