EMA Backs First Oral Treatment for Hereditary Angioedema
At its July 2025 meeting, the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending marketing authorization for sebetralstat (Ekterly, KalVista Pharmaceuticals) for symptomatic treatment of acute attacks of hereditary angioedema in adults and adolescents aged 12 years or older. Hereditary angioedema is a rare, chronic, and potentially life-threatening genetic condition caused by deficiency or dysfunction of C1 esterase inhibitor, leading to excessive bradykinin and unpredictable swelling episodes in the face, abdomen, limbs, and airways. Sebetralstat is a selective oral plasma kallikrein inhibitor designed for administration at the earliest sign of an angioedema attack. It blocks the overactivation of the kallikrein-kinin system, preventing the formation of bradykinin, a key mediator of swelling in the condition. If approved by the European Commission, the drug will be the first oral on-demand treatment for hereditary angioedema in the European Union. The CHMP opinion was based on efficacy and safety data from a phase 3 KONFIDENT trial, which randomized 136 patients with hereditary angioedema. Findings showed that sebetralstat led to significantly faster symptom relief and reduction in attack severity and attack resolution than placebo. It was also well-tolerated with a safety profile similar to placebo. Ekterly will be available in 300-mg film-coated tablets. The most common side effect reported is headache. One of the key advantages of the drug is its oral route of administration, offering patients a more convenient alternative to injectable therapies. This may significantly reduce the time between an angioedema attack onset and treatment administration. Ekterly was granted orphan medicine status during its development due to its targeted use in a rare, life-threatening condition. The EMA noted that the drug would have been unlikely to be developed without such incentives and is now reviewing the available data to determine whether the orphan designation should be maintained.

KalVista Pharmaceuticals Receives Positive CHMP Opinion for Sebetralstat for the Treatment of Hereditary Angioedema Attacks
CAMBRIDGE, Mass. & SALISBURY, England--(BUSINESS WIRE)--KalVista Pharmaceuticals, Inc. (Nasdaq: KALV) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending marketing authorization for sebetralstat, a novel oral plasma kallikrein inhibitor, for symptomatic treatment of acute attacks of hereditary angioedema (HAE) in adults and adolescents aged 12 years and older. The European Commission (EC) final decision is expected by early October. 'This positive CHMP opinion is an important step forward for people living with HAE in Europe, where there remains a high need for effective, easy-to-administer on-demand treatments,' said Ben Palleiko, CEO of KalVista. 'Coming just weeks after regulatory approvals in the US and UK, this milestone highlights the potential of sebetralstat to transform how HAE is managed globally. Sebetralstat is expected to become the first and only oral on-demand treatment for HAE available in Europe, bringing forward a new treatment approach that enables adherence to guidelines and empowers people to treat attacks quickly, wherever they occur.' The CHMP based its opinion on results from the phase 3 KONFIDENT clinical trial, which was the largest clinical trial ever conducted in HAE. Data from KONFIDENT was published in the New England Journal of Medicine in May 2024, showing that sebetralstat achieved significantly faster symptom relief, reduction in attack severity and attack resolution than placebo, and was well-tolerated with a safety profile similar to placebo.1 The trial randomized 136 HAE patients from 66 clinical sites across 20 countries. 'Access to on-demand treatments that offer easy self-administration and rapid symptom relief is critical for patients living with HAE,' said Emel Aygören-Pürsün, M.D., Assistant Professor, Internal Medicine and Hemostaseology, Department for Children and Adolescents, University Hospital Frankfurt. 'Until now, on-demand therapies for HAE attacks required parenteral administration via injections. The positive CHMP opinion for sebetralstat is an essential move toward a novel, long-awaited oral on-demand option that could help patients treat attacks early and independently, as advocated by guidelines, with the goal of improving outcomes and normalizing lives.' Sebetralstat is approved in the United States and United Kingdom under the brand name EKTERLY® for the treatment of HAE attacks in people 12 years of age and older. It is currently under review with regulatory authorities in Japan as well as multiple other territories. About Hereditary Angioedema Hereditary angioedema (HAE) is a rare genetic disease resulting in deficiency or dysfunction in the C1 esterase inhibitor (C1INH) protein and subsequent uncontrolled activation of the kallikrein-kinin system. People living with HAE experience painful and debilitating attacks of tissue swelling in various locations of the body that can be life-threatening depending on the area affected. Treatment guidelines recommend treating attacks as early as possible to prevent progression of swelling and shorten the time to attack resolution, and to consider treatment for all attacks, regardless of anatomic location or severity. About Sebetralstat Sebetralstat is a novel plasma kallikrein inhibitor approved in the United States and United Kingdom for the treatment of acute attacks of hereditary angioedema (HAE) in people 12 years of age and older. It is the first and only oral on-demand treatment for HAE. With ongoing studies exploring its use in children aged two to 11 and multiple regulatory applications under review in key global markets, sebetralstat has the potential to become the foundational therapy for HAE management worldwide.

(Nasdaq: KALV), today provided an operational update and released financial results for the fiscal year ended April 30, 2025. "The FDA approval of EKTERLY represents a major milestone—not only as the first commercial product for KalVista, but more importantly, as the first and only oral on-demand therapy for people living with HAE," said Ben Palleiko, CEO of KalVista Pharmaceuticals. "EKTERLY delivers a long-awaited treatment that is safe, effective, and easy to administer. Our commercial team is actively engaging in the field, leveraging their expertise to educate and activate patients and physicians to enable timely access, drive awareness, and support informed treatment decisions around this important new therapy. With commercial partners now in place in Canada and Japan, and six global regulatory submissions under review, we believe EKTERLY is poised to become the foundational therapy for HAE management worldwide." Recent Business Highlights EKTERLY® (sebetralstat) On July 7, 2025, KalVista announced FDA approval of EKTERLY (sebetralstat), a novel plasma kallikrein inhibitor, for the treatment of acute attacks of hereditary angioedema (HAE) in adult and pediatric patients aged 12 years and older. KalVista further strengthened the robust body of clinical evidence supporting the efficacy and safety of EKTERLY (sebetralstat) for the treatment of HAE. The Company presented new data at the European Academy of Allergy and Clinical Immunology Congress 2025 (EAACI), the 14th C1-inhibitor Deficiency & Angioedema (C1-INH) Workshop in Budapest, Hungary, and the Eastern Allergy Conference (EAC) in Palm Beach, Florida. Key highlights from these medical congresses are outlined below: EAACI: Data showed the efficacy of EKTERLY (sebetralstat) for the on-demand treatment of HAE attacks among patients receiving long-term prophylaxis (LTP). Real world data highlighted significant challenges with LTP adherence, and ongoing reliance on on-demand medications. In KONFIDENT-S, EKTERLY (sebetralstat) delivered rapid, consistent relief for attacks, regardless of LTP mechanism of action with a median time to beginning of symptom relief of 1.3 hours. C1-INH: Analysis from nearly 1,600 attacks in KONFIDENT-S showed a median time to end of attack progression of 19.8 minutes. These results aligned closely with KONFIDENT, reinforcing the rapid effect of EKTERLY (sebetralstat) after absorption. Interim data from KONFIDENT-S highlighted the role of EKTERLY (sebetralstat) in treating mucosal attacks with a median time to beginning of symptom relief of 1.3 hours for both abdominal and laryngeal attacks. EAC: In KONFIDENT-S, EKTERLY (sebetralstat) was used to treat 76 attacks that had progressed to severe or very severe after a median of 2.16 hours from attack onset, demonstrating its utility in more advanced stages of HAE attacks. The median time to beginning of symptom relief for these attacks was 1.36 hours, with reduction in attack severity and substantial reduction of symptom burden in a median of 1.77 hours and 9.15 hours, respectively. Organizational In April, KalVista entered into an exclusive agreement with Kaken Pharmaceutical, Co., Ltd. to commercialize sebetralstat in Japan. Under the terms of the deal, in June 2025 KalVista received an upfront payment of $11 million, and an additional $11 million will be paid upon achieving a regulatory milestone anticipated in early 2026. This agreement also includes potential commercial milestone payments of up to $2 million and royalties based on the Japan National Health Insurance (NHI) price, with royalties expected to be in the mid-twenties as a percentage of sales. In June, KalVista granted Pendopharm, a division of Pharmascience Inc., the exclusive rights to manage the regulatory approval process and commercialization of sebetralstat in Canada. Financial Results for Fiscal Year Ended April 30, 2025: Research and development expenses were $71.7 million and $86.2 million for the fiscal years ended April 30, 2025, and 2024, respectively. The decrease in R&D was primarily attributable to reduced clinical trial expenses, preclinical activities and recognizing expense associated with EKTERLY (sebetralstat) pre-commercial awareness within General & Administrative. General and administrative expenses were $116.3 million and $54.3 million for the fiscal years ended April 30, 2025, and 2024, respectively. The increase in G&A expenses was primarily due to pre-commercial planning expenses related to EKTERLY (sebetralstat). Cash, cash equivalents and marketable securities were $220.6 million on April 30, 2025, compared to $210.4 million on April 30, 2024. About KalVista Pharmaceuticals, Inc.

FDA Approves First Oral Treatment for Rare Swelling Disorder
July 8, 2025 – The FDA has approved the first-ever pill for a rare genetic swelling disorder. The drug, known as sebetralstat but sold as Ekterly, is for adults and children age 12 years or older with hereditary angioedema (HAE), which affects about 1 in 50,000 people and causes sudden and painful swelling that can sometimes be life-threatening. These easy-to-take pills help stop an attack whenever it happens, offering an advantage over other treatments that need to be injected either into the veins or under the skin. HAE happens when a person has a faulty gene that causes their body to make too little of a protein called C1 inhibitor, or the protein doesn't work well. This protein usually helps control swelling and inflammation in the body. This genetic defect can cause swelling in the face, throat, abdomen, or limbs, which can sometimes be serious. Those with the condition who have swelling in the abdomen can have stomach pain, vomiting, or diarrhea. Swelling in the throat or face can make it hard to breathe. Even with regular treatment, many people with HAE still have sudden attacks and always need fast-acting medicine available to them. "As the first orally administered on-demand therapy for HAE attacks, Ekterly provides patients and physicians with an important and welcome advance in HAE treatment options," Anthony J. Castaldo, chief executive officer of the US Hereditary Angioedema Association, said in a statement. Ekterly was approved after a study involving 136 people with HAE across 20 countries showed that it could quickly relieve symptoms and help end attacks sooner, compared to a placebo, regardless of how severe the attack was. In a follow-up study, many people were able to take the pill within 10 minutes of an attack, and symptoms began to improve in about 1.3 hours, according to a news release from KalVista Pharmaceuticals, the drug's maker. Ekterly works by blocking an enzyme called plasma kallikrein, which causes swelling. In people with HAE, this enzyme is too active because the C1 inhibitor protein does not work properly. By blocking this enzyme, Ekterly helps stop sudden swelling and pain from happening. The pill lets people treat attacks early, giving them more control and helping doctors lower the impact of the disease. According to KalVista, the medicine will be available right away. Headaches are the only reported side effect of the new treatment. It's not known if the medicine is safe during pregnancy or breastfeeding, so patients should tell their doctor if they are pregnant, planning to become pregnant, or breastfeeding. Patients should also tell their doctor if they have liver problems or are taking other medicines, especially for fungal or viral infections, or epilepsy.
