CAMBRIDGE, Mass. & SALISBURY, England - KalVista Pharmaceuticals, Inc. (NASDAQ: NASDAQ:KALV) has presented new data at the American College of Allergy Asthma and Immunology (ACAAI) demonstrating the potential of sebetralstat, an oral plasma kallikrein inhibitor, for the on-demand treatment of hereditary angioedema (HAE). The presentations included findings from the Phase 3 KONFIDENT trial, which suggested that earlier treatment with sebetralstat led to faster resolution of HAE attacks.
Tim Craig, DO, of Penn State Health, highlighted that complete attack resolution was achieved more quickly when treatment was initiated sooner. The Phase 3 trial data showed that attacks treated in the earliest phase (1st quartile) resolved faster than those treated later (4th quartile). This supports the clinical value of early treatment for HAE attacks, which can be life-threatening due to tissue swelling in various parts of the body.
William Lumry, MD, from the AARA Research Center in Dallas, presented data indicating that sebetralstat significantly reduced symptom burden compared to placebo. In attacks that had reached at least moderate severity before treatment, sebetralstat led to a median time of symptom relief of approximately 5 hours, in contrast to over 12 hours with placebo.
The data also included an indirect comparison between oral sebetralstat and intravenous recombinant C1-inhibitor (IV rhC1-INH), showing no significant differences in the time to the beginning of symptom relief. Furthermore, a pooled analysis from the KONFIDENT and KONFIDENT-S trials found that sebetralstat treated laryngeal HAE attacks effectively, with median times to beginning of symptom relief and to complete attack resolution being 1.5 and 9.7 hours, respectively.
The presentations underscored the challenges HAE patients face with current on-demand treatments, which require intravenous or subcutaneous administration, and often lead to delays in treatment due to the invasiveness of the methods. Sebetralstat, if approved, could offer a less invasive and more accessible treatment option.
Sebetralstat has received Fast Track and Orphan Drug Designations from the U.S. FDA, and is currently under regulatory review with a Prescription Drug User Fee Act (PDUFA) goal date of June 17, 2025. KalVista has also submitted marketing authorization applications for sebetralstat in several other regions, including the European Union and the United Kingdom.
The information presented is based on a press release statement from KalVista Pharmaceuticals, Inc. The company continues to develop sebetralstat and other treatments for rare diseases, aiming to provide life-changing oral medicines to patients with significant unmet needs.
In other recent news, KalVista Pharmaceuticals has made significant strides in the development of sebetralstat, a potential treatment for hereditary angioedema (HAE). The company recently presented new findings at the HAEi Global Angioedema Forum, highlighting the drug's effectiveness in reducing anxiety related to HAE attacks. This data was drawn from the KONFIDENT Phase 3 clinical trial, which revealed its top line results earlier this year.
KalVista has also submitted Marketing Authorization Applications for sebetralstat to regulatory authorities in the United Kingdom, Switzerland, Australia, and Singapore. The U.S. FDA has set a Prescription Drug User Fee Act (PDUFA) date of June 17, 2025, for sebetralstat. In addition to these developments, the company has announced the appointment of a new CFO, Brian Piekos, who brings over 25 years of financial and strategic planning experience in the biopharmaceutical industry.
In terms of analyst ratings, H.C. Wainwright and Leerink Partners have reiterated a Buy and Outperform rating respectively, while Jones Trading initiated coverage on KalVista, issuing a Buy rating. These ratings and developments underscore the recent progress KalVista has made in its ongoing efforts to provide innovative treatments for diseases with significant unmet medical needs.
