– Submitted NDA for sebetralstat as first-ever, oral on-demand treatment for HAE attacks, a pivotal moment for the HAE community –

– Potential FDA approval and launch of sebetralstat in first half 2025 -

KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), today provided an operational update and released financial results for the fiscal year ended April 30, 2024.

“This last fiscal quarter was the most important in the history of KalVista,” said Ben Palleiko, CEO of KalVista. “Not only did we submit the NDA for sebetralstat to the FDA, but the KONFIDENT phase 3 trial results were published in The New England Journal of Medicine, supporting our view on the importance of this potential therapy. We look forward to building on these milestones as we submit additional marketing authorization applications to other national health authorities throughout 2024 and anticipate approval and launch in the US in the first half of 2025.”

Fiscal 2024 and Recent Business Highlights:

Sebetralstat

• In June 2024, KalVista submitted a New Drug Application (NDA) for U.S. Food and Drug Administration (FDA) review of sebetralstat, a novel investigational oral plasma kallikrein inhibitor for the treatment of hereditary angioedema (HAE) attacks in adults and pediatric patients aged 12 years and older.
• Also in June, the Company initiated ahead of schedule 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. 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 phase 3 KONFIDENT trial of sebetralstat was published in the New England Journal of Medicine (NEJM) and presented concurrently at the European Academy of Allergy and Clinical Immunology Congress 2024 (EAACI).
• Presented the U.S. subgroup analysis from the phase 3 KONFIDENT trial at the Eastern Allergy Conference (EAC) 2024, as well as the Japanese subgroup from KONFIDENT at the 123^rd Annual Meeting of the Japanese Dermatological Association (JDA) 2024.
• KalVista is on track for Market Authorization Application submissions to both European Medicines Agency and UK Medicines and Healthcare Products Regulatory Agency in Q3 2024 as well as a JNDA submission to the Japanese Pharmaceuticals and Medical Devices Agency in Q4 2024.

Oral Factor XIIa Inhibitor Program

• The Company believes its preclinical Factor XIIa inhibitor program may have the potential to yield the first orally delivered Factor XIIa inhibitor for a variety of therapeutic indications. KalVista is undergoing a strategic review of this program to evaluate the potential for further development.

Organizational

• In March 2024, KalVista announced the promotion of Benjamin L. Palleiko to Chief Executive Officer and his appointment as a member of the Board.
• In February, KalVista entered into an underwriting agreement with Jefferies LLC, Leerink Partners LLC, Stifel, Nicolaus & Company, Incorporated, and Cantor Fitzgerald & Co., as the representatives of several underwriters to sell an aggregate of 7,016,312 shares of the Company’s common stock at price of $15.25 per share and pre-funded warrants to purchase up to 3,483,688 shares of common stock at a price of $15.249 per pre-funded warrant. The net proceeds from the Offering, after deducting estimated expenses, were approximately $150.1 million.
• In April, William C. Fairey was appointed to the KalVista Board of Directors.

Fourth Quarter and Full Year Financial Results:

• Revenue: No revenue was recognized for the three months and fiscal years ended April 30, 2024, or April 30, 2023, respectively.
• R&D Expenses: Research and development expenses were $25.3 million for the three months ended April 30, 2024, compared to $24.0 million for the same period in the prior fiscal year. Research and development expenses were $86.2 million for the fiscal year ended April 30, 2024, compared to $80.3 million for the prior fiscal year. The increase in spending in the fiscal year ended April 30, 2024 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 $23.2 million for the three months ended April 30, 2024, compared to $7.8 million for the same period in the prior fiscal year. General and administrative expenses were $54.3 million for the fiscal year ended April 30, 2024, compared to $30.6 million for the prior fiscal year. The increase in G&A expenses was primarily due to increases in employee-related expenses and commercial planning expenses.
• Net Loss: Net loss was $44.7 million, or $(1.02) per weighted average basic and diluted share, for the three months ended April 30, 2024, compared to net loss of $26.3 million, or $(0.77) per weighted average basic and diluted share for the same period in the prior fiscal year. Net loss was $126.6 million, or $(3.44) per weighted average basic and diluted share for the fiscal year ended April 30, 2024, compared to net loss of $92.9 million, or $(3.33) per weighted average basic and diluted share 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 $210.4 million on April 30, 2024, compared to $149.4 million on April 30, 2023. The increase in the net cash and marketable securities position was primarily due to the net proceeds received from the February 2024 underwritten offering of common stock and pre-funded warrants.
