KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), today provided an operational update and released financial results for the first fiscal quarter ended July 31, 2024.

“We are excited about the steady progress we’ve made over the last few months including the most recent acceptance of our NDA by FDA and the EMA’s validation of our MAA,” said Ben Palleiko, CEO of KalVista. “We look forward to building on these recent milestones as we move toward filing for approval in the UK, Japan, and other countries later in 2024 and aim for our first commercial launch of sebetralstat in June 2025. I am grateful for the hard work of the entire KalVista team as we remain dedicated to getting this important treatment to people living with HAE.”

First Fiscal Quarter and Recent Business Highlights:

Sebetralstat

• In September, KalVista announced the U.S. Food and Drug Administration (FDA) accepted its New Drug Application (NDA) for sebetralstat, a novel, investigational oral plasma kallikrein inhibitor for the on-demand treatment of hereditary angioedema (HAE) attacks in adult and pediatric patients aged 12 years and older. The FDA has set a Prescription Drug User Fee Act (PDUFA) goal date of June 17, 2025.
• Last month, the Company announced that the European Medicines Agency (EMA) validated the submission of the Marketing Authorization Application (MAA) for sebetralstat.
• KalVista expects to file for approval in the UK, Japan, and other countries later in 2024. The Company has also engaged with the Access Consortium to maximize regulatory collaboration across countries and support a timely review process.
• In June, ahead of schedule, KalVista initiated a pediatric clinical trial (KONFIDENT-KID) using an orally disintegrating tablet (ODT) formulation of sebetralstat designed for this population. KONFIDENT-KID will enroll approximately 24 children, with an age range of 2 to 11 years, across seven countries in North America, Europe and Asia. The trial has since started dosing patients and if approved, sebetralstat would be the first oral, on demand treatment for this population and only the second approved on-demand therapy of any type.
• Data from the phase 3 KONFIDENT trial of sebetralstat was published in the New England Journal of Medicine (NEJM) and presented at the European Academy of Allergy and Clinical Immunology Congress 2024 (EAACI).

First Fiscal Quarter Financial Results

• Revenue: No revenue was recognized for the three months ended July 31, 2024, or July 31, 2023, respectively.
• R&D Expenses: Research and development expenses were $26.6 million for the three months ended July 31, 2024, compared to $19.3 million for the same period in the prior fiscal year. The increase in R&D expenses during the quarter primarily reflects the phase 3 KONFIDENT trial which concluded in February 2024, the ongoing KONFIDENT-S trial, and a headcount driven increase in personnel costs.
• G&A Expenses: General and administrative expenses were $17.6 million for the three months ended July 31, 2024, compared to $9.8 million for the same period in the prior fiscal year. The increase in G&A expenses was primarily due to increases in commercial planning expenses and employee-related expenses.
• Net Loss: Net loss was $40.4 million, or $(0.87) per weighted average basic and diluted share, for the three months ended July 31, 2024, compared to net loss of $25.3 million, or $(0.74) per weighted average basic and diluted share for the same period in the prior fiscal year. The increase in net loss and net loss per share primarily resulted from the increase in operating expenses, both research and development and general and administrative.
• Cash position: Cash, cash equivalents and marketable securities were $174.3 million on July 31, 2024, compared to $210.4 million on April 30, 2024. The decrease in the net cash and marketable securities position was due to cash consumption from operating expenses.
