CAMBRIDGE, Mass. & SALISBURY, England--(BUSINESS WIRE)--KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), today announced the presentation of new sebetralstat data at the American College of Allergy Asthma and Immunology (ACAAI) taking place in Boston, MA from October 24 - 28, 2024.
Tim Craig, DO, Professor, Departments of Medicine and Pediatrics, Division of Pulmonary, Allergy and Critical Care Medicine, Penn State Health, and KONFIDENT investigator, presented data on the Correlation of Time to Treatment with Attack Duration in the Sebetralstat KONFIDENT Phase 3 Trial that showed complete attack resolution was achieved faster in attacks that were treated earlier (1st quartile) compared with those treated later (4th quartile).
“This is the first time in a Phase 3 on-demand trial where we can see that treating attacks within minutes versus hours has a meaningful impact on clinical outcomes. While injectable on-demand therapies are effective, there are numerous barriers patients face that lead to delay or denial of HAE on-demand treatment,” said Dr. Craig. “These data help to clarify the potential value of sebetralstat if approved: reduced burden enabling patients to treat attacks early and achieve earlier symptom relief and shorter attack duration.”
William Lumry, MD, Medical Director AARA Research Center, Dallas and KONFIDENT investigator, presented data on the Substantial Reduction of HAE Symptom Burden in the Sebetralstat Phase 3 KONFIDENT Trial which showed that among attacks that had progressed to at least moderate severity on the Patient Global Impression of Severity (PGI-S) prior to treatment, those treated with sebetralstat 300mg (n=49, P=0.002) and sebetralstat 600mg (n=52, P=0.034) achieved a faster reduction in substantial symptom burden (reduction in PGI-S to “mild”) than with placebo (n=46), with median times of 5.0 hours, 5.2 hours, and >12 hours, respectively.
“All other clinical trial designs for on-demand therapy have required attacks to be at least moderate in severity to be eligible to treat. This changed with the sebetralstat Phase 2 and 3 trials which, consistent with modern HAE guidelines, instructed patients to treat attacks early. Despite this, approximately half of attacks progressed in severity prior to treatment,” said Dr. Lumry. “Among these more severe attacks, which were treated somewhat later, sebetralstat reduced symptom burden to “mild” significantly faster than placebo, with a median time of approximately 5 hours for sebetralstat vs >12 hours for placebo.”
The following are details for the additional ePoster - Meet the Author data presentations at ACAAI 2024:
“The HAE community has long sought a less invasive treatment option that combines needed efficacy with lower treatment burden. These presentations continue to demonstrate that sebetralstat has the potential to provide injectable-like efficacy in a pill,” said Ben Palleiko, CEO of KalVista Pharmaceuticals. “If approved, sebetralstat will be the only on-demand treatment option that will have demonstrated the ability to enable compliance with treatment guidelines that call for early treatment of attacks, regardless of severity or location.”

About Sebetralstat
Discovered and developed entirely by the scientific team at KalVista, sebetralstat is a novel, investigational oral plasma kallikrein inhibitor for the on-demand treatment of hereditary angioedema (HAE). Sebetralstat received Fast Track and Orphan Drug Designations from the U.S. FDA, as well as Orphan Drug Designation and an approved Pediatric Investigational Plan from the European Medicines Agency (EMA).
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 location affected. All currently approved on-demand treatment options require either intravenous or subcutaneous administration.
