KalVista Pharmaceuticals, Inc. (NASDAQ:KALV), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of oral, small molecule protease inhibitors, today provided an operational update and released financial results for the third fiscal quarter ended January 31, 2024.

"This has been an exciting and busy period for KalVista, as we achieved key milestones with the release of our phase 3 KONFIDENT data and the completion of a substantial financing," said Ben Palleiko, Chief Executive Officer of KalVista. "We remain on track to file the NDA with the U.S. Food and Drug Administration in the first half of this year, and we look forward to presenting further phase 3 data for sebetralstat at upcoming patient and medical meetings. We also continue to grow the commercial organization to enable us to deliver on the promise of providing the first oral, on-demand treatment option to the HAE community."

Third Fiscal Quarter and Recent Business Highlights:

• In February, the Company announced positive topline data from the Phase 3 KONFIDENT clinical trial evaluating the safety and efficacy of sebetralstat as the potential first oral, on-demand therapy for hereditary angioedema (HAE). KONFIDENT was the largest and most representative trial ever conducted in HAE, enrolling a total of 136 patients from 66 clinical sites across 20 countries. Eligible participants included adolescents, patients using long-term prophylaxis, and the trial evaluated all attack severities and locations. The clinical trial met all primary and key secondary endpoints across both the 300 and 600 mg doses and demonstrated a safety profile similar to placebo.
• Also in February, KalVista closed an underwritten offering to sell an aggregate of 7,016,312 shares of 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 were approximately $150.1 million and are expected to provide funding into 2026.
• The Company announced that Benjamin L. Palleiko, the Company's prior President, CBO and CFO, was appointed as Chief Executive Officer and a director of the Company. This appointment is the result of a planned transition as KalVista prepares to become a commercial entity following the success of the KONFIDENT Phase 3 trial for its program sebetralstat.
• The UK Medicines and Healthcare products Regulatory Agency (MHRA) awarded the Innovation Passport for sebetralstat, providing entry to the UK Innovative Licensing and Access Pathway (ILAP), which aims to accelerate time to market and facilitate patient access to innovative medicines.
• Presented additional Phase 3 KONFIDENT data as well as data on unmet need in HAE from a patient perspective at the 2024 American Academy of Allergy Asthma & Immunology Annual Meeting (AAAAI) in Washington, D.C.
• Announced publication of the first report of a potent and specific Factor XIIa inhibitor with high oral availability in a peer-reviewed journal. The Frontiers in Pharmacology article describes the pharmacology of a representative compound from KalVista's portfolio of structurally diverse, oral Factor XII inhibitors.

Third Fiscal Quarter Financial Results:

Revenue: No revenue was recognized for the three months ended January 31, 2024, or January 31, 2023.

R&D Expenses: Research and development expenses were $22.5 million for the three months ended January 31, 2024, compared to $20.1 million for the same period in the prior fiscal year. The increase in R&D expenses during the quarter primarily reflects the ongoing Phase 3 KONFIDENT and KONFIDENT-S trials.

G&A Expenses: General and administrative expenses were $10.6 million for the three months ended January 31, 2024, compared to $6.9 million for the same period in 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 $29.0 million, or $(0.84) per weighted average basic and diluted share, for the three months ended January 31, 2024, compared to net loss of $21.3 million, or $(0.75) per weighted average basic and diluted share for the same period in the prior fiscal year. The increase in net loss primarily resulted from the increase in operating expenses, primarily research and development.

Cash Position: Cash, cash equivalents and marketable securities were $75.6 million as of January 31, 2024, compared to $149.4 million as of April 30, 2023. The decrease in the net cash and marketable securities position was due to cash consumption from operating expenses.
