The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) approved Sebetralstat (Ekterly) on July 15, 2025, as the first oral on-demand treatment for hereditary angioedema (HAE) in patients aged 12 and older.
This approval marks a significant advancement in HAE treatment, offering a non-injectable option that promises quicker relief during acute attacks.
Revolutionizing HAE Management with Sebetralstat
The MHRA’s recent approval of Sebetralstat, sold under the brand name Ekterly, introduces a groundbreaking shift in the treatment of hereditary angioedema (HAE) — a rare genetic disorder characterized by sudden and severe swelling.
This is the first time an oral medication has been available for on-demand treatment of HAE attacks, providing a significant alternative to the injectable treatments that have been standard until now.
Sebetralstat works by effectively blocking bradykinin, a peptide that plays a crucial role in the physiological processes leading to swelling during HAE attacks. This mechanism addresses the root cause of the condition more directly than previous treatments.
Insights from the KONFIDENT Clinical Trial
The approval was supported by results from the KONFIDENT clinical trial, which demonstrated that Sebetralstat significantly reduces the time to relief from HAE attacks compared to placebo.
Patients using Sebetralstat reported experiencing faster cessation of symptoms, which is critical in managing acute episodes of the disease.
The trial also highlighted the drug’s safety profile, with the most common side effects being mild to moderate headaches and gastrointestinal issues. These findings underscore the treatment’s efficacy and manageable tolerability, making it a viable option for many patients.
Expanding Treatment Accessibility for Adolescents
One of the notable aspects of Sebetralstat’s approval is its authorization for use in adolescents aged 12 and over. This approval expands the treatment options available to younger patients, who may particularly benefit from an oral medication over injectables due to ease of administration and less invasive nature.
By allowing treatment initiation at the onset of symptoms, Sebetralstat empowers adolescents and their caregivers to manage attacks promptly and effectively, potentially reducing the need for emergency medical interventions.
Streamlined Regulatory Approval via NASWSI
The approval of Sebetralstat was expedited through the Access Consortium’s NASWSI procedure, which is designed to streamline the regulatory process for drugs that are approved in multiple jurisdictions within the EU and UK.
This collaborative approach not only speeds up the availability of new treatments but also aligns regulatory standards across member countries.
This method of approval indicates a strong regulatory confidence in the safety and efficacy of Sebetralstat, setting a precedent for future treatments undergoing the same process.

How Global Trends Are Shaping Tomorrow’s World
Following its approval by the MHRA, Sebetralstat is set to have a significant impact on the global treatment landscape for HAE. The drug’s approval in the UK follows closely on the heels of its endorsement by the FDA in the United States, signaling a broad international consensus on its benefits and safety.
This dual approval enhances the drug’s potential for widespread adoption and may influence future research and development in treatments for rare diseases, particularly those requiring rapid symptom management.
Voices from the Industry: Julian Beach’s Perspective
Julian Beach, MHRA Interim Executive Director, emphasized the importance of patient safety in the approval process:
“Patient safety is our top priority, which is why we’re pleased to approve Sebetralstat… HAE attacks can have sudden serious impacts… This approval is the first oral option, valuable for patients preferring alternatives to injections.”
This statement highlights the regulatory body’s commitment to advancing healthcare options that not only meet stringent safety standards but also enhance patient quality of life by providing more accessible treatment forms.
