KalVista Pharmaceuticals, Inc. (NASDAQ:KALV), today released financial results for the third fiscal quarter ended January 31, 2025, and provided an operational update.

"Sebetralstat is poised to be the first and only oral on-demand treatment for HAE, with the potential to become the foundational treatment for this disease," said Ben Palleiko, Chief Executive Officer of KalVista. "With seven regulatory submissions globally and the first regulatory approval expected in June, we are confident in our ability to achieve commercial success. Our robust data set, including recent presentations at WSAAI and AAAAI, demonstrates how sebetralstat could address critical unmet needs, particularly for vulnerable populations, such as those experiencing HAE attacks despite LTP, adolescents with HAE, and individuals facing laryngeal attacks. We continue to receive positive feedback from healthcare providers and people living with the disease, who share their excitement about the potential of an oral, on-demand option that offers both high efficacy and low treatment burden."

Third Fiscal Quarter and Recent Business Highlights

Sebetralstat

• In January 2025, KalVista announced that Japan's Ministry of Health, Labour and Welfare (MHLW) granted Orphan Drug Designation to sebetralstat, alongside the Company's submission of a New Drug Application (NDA) for sebetralstat in that country. This marks the Company's seventh regulatory submission since mid-2024, including to the U.S. FDA, which issued a PDUFA goal date of June 17, 2025. The Company has also completed submissions to the U.K., Switzerland, Australia, Singapore, and the European Medicines Agency, which validated the Marketing Authorization Application in August 2024.
• KalVista continued to build on the extensive clinical evidence demonstrating the efficacy and safety of sebetralstat for HAE. The Company presented new sebetralstat data at the 2025 Western Society of Allergy, Asthma, and Immunology (WSAAI) and the American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting. Key highlights from these medical congresses are outlined below:
  • WSAAI
    • Data from KONFIDENT-S showed patients on LTP averaged 1.7 HAE attacks per month and showed symptom relief for treated attacks with sebetralstat in a median of 1.3 hours. These results confirm that sebetralstat was shown to be effective for the on-demand treatment of HAE attacks regardless of the type of LTP therapy used.
  • AAAAI
    • Interim analysis from KONFIDENT-S showed sebetralstat enabled prompt treatment response of laryngeal HAE attacks with a median time of 1 hour and 16 minutes to onset of symptom relief. No patient reported difficulty swallowing the film-coated tablet.
    • Pooled survey analysis showed adolescents treated attacks with sebetralstat in a median of 4 minutes after onset of symptoms compared to over 3 hours based on international survey data presented at the meeting.
• KalVista will host a virtual investor day on Tuesday, March 25th, at 8:00 a.m. ET, highlighting the commercialization strategy and launch plans for sebetralstat. The event will include presentations by members of the KalVista executive team and key healthcare experts in the field of HAE.

Organizational

• In preparation for the anticipated U.S. commercial launch, KalVista has fully onboarded its field sales team, comprised of experts in HAE, allergy, and rare diseases.
• Strengthening its leadership, the Company appointed Jeb Ledell as Chief Operating Officer and Chris Hamblett, PhD, Senior Vice President of Corporate Development.
• In November 2024, KalVista raised a total of $160 million in aggregate gross proceeds through concurrent synthetic royalty financing and equity offerings. The synthetic royalty financing agreement with DRI Healthcare provides up to $179 million in non-dilutive funding, including $100 million upfront. In addition, the Company closed a public offering raising $55 million as well as $5 million in a private placement to DRI Healthcare.

Third Fiscal Quarter Financial Results

• The Company did not record any revenue for the three months ended January 31, 2025 or three months ended January 31, 2024.
• Research and development expenses were $12.6 million for the three months ended January 31, 2025, compared to $22.5 million for the same period in the prior fiscal year. The decrease was primarily attributable to reduced clinical trial expenses, preclinical activities and recognizing expense associated with sebetralstat pre-commercial awareness within General & Administrative.
• General and administrative expenses were $30.3 million for the three months ended January 31, 2025, compared to $10.6 million for the same period in the prior fiscal year. The increase was primarily due to pre-commercial planning activities related to sebetralstat.
• As of January 31, 2025, the Company had cash, cash equivalents and marketable securities of approximately $253.2 million.
