• Sebetralstat Phase 3 KONFIDENT Clinical Trial Achieves Target Enrollment; Data Readout on Track for Q4 
• Preparations Continue for NDA filing H1 2024 and Rapid Commercialization Upon Approval 

CAMBRIDGE, Mass. & SALISBURY, England / Sep 07, 2023 / Business Wire / 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 first fiscal quarter ended July 31, 2023.

“We know from our extensive interactions with people living with hereditary angioedema (HAE) at the recent conferences how much they are anticipating having sebetralstat available to them, and the data from the KONFIDENT trial in Q4 is the next step,” said Andrew Crockett, Chief Executive Officer of KalVista. “We continue to build our Commercial operation with the addition of Nicole Sweeny as Chief Commercial Officer and other key members of the team to support an NDA submission in the first half of 2024 and a rapid launch upon FDA approval.”

First Fiscal Quarter and Recent Business Highlights:

• Published “Evaluation of patient-reported outcome measures for on-demand treatment of hereditary angioedema attacks and design of KONFIDENT, a phase 3 trial of sebetralstat” in Clinical and Translational Allergy. This publication outlines the rigorous, multi-factorial approach used to design a phase 3 trial with an optimized, patient- and physician-preferred measure to assess measure efficacy, and discusses reasons for the superiority of the selected primary endpoint over other potential measures
• Presented real-world patient data on the HAE Attack Journey at the HAEi Regional Conference EMEA meeting showing there remain important unmet needs for both people using only on-demand therapies as well as those on long-term prophylaxis
• Achieved enrollment target of 114 patients in the phase 3 KONFIDENT trial. Data readout remains on track for the fourth quarter of 2023 and, if the trial is successful, KalVista anticipates submitting an NDA to the FDA in the first half of 2024
• Presented real-world patient data at the 2023 US HAEA National Summit showing people living with HAE continue to delay treatment for attacks due to challenges from injections or infusions, even though they know early treatment means an earlier return to normal activities
• Announced that Nicole Sweeny joined the Senior Leadership Team at KalVista as Chief Commercial Officer
• Reported new data in five posters at the 2023 Meeting of the European Academy of Allergy and Clinical Immunology. The presentations showed that sebetralstat pharmacokinetic and pharmacodynamic data support globalization of the KONFIDENT phase 3 clinical trial and use in short-term prophylaxis and that patients receiving modern long-term prophylaxis continued to have challenges associated with treatment decisions
• Presented at the 2023 Jefferies Global Healthcare Conference, Stifel Tailoring Genes: Genetic Medicines Day and Stifel Biotech Summer Summit
• Revealed patient survey data at the 13th C1-inhibitor Deficiency & Angioedema Workshop demonstrating the burden associated with injectable on-demand treatments for HAE and that those living with HAE had a strong preference for oral medication for on-demand treatment of attacks over self-administered injectable treatments when efficacy and safety profiles were similar
• Continued to advance plans for the eventual worldwide launch of sebetralstat by hiring a General Manager, Japan. Based on interactions to date with Japanese physicians and regulatory authorities, KalVista believes sebetralstat has the potential to significantly improve HAE therapeutic options in Japan.

First Fiscal Quarter Financial Results:

Revenue: No revenue was recognized for the three months ended July 31, 2023 or July 31, 2022.

R&D Expenses: Research and development expenses were $19.3 million for the three months ended July 31, 2023, compared to $18.2 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 trial for sebetralstat and increased personnel costs.

G&A Expenses: General and administrative expenses were $9.8 million for the three months ended July 31, 2023, compared to $8.1 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 professional fees.

Net Loss: Net loss was $25.3 million, or $(0.74) per weighted average basic and diluted share, for the three months ended July 31, 2023, compared to net loss of $23.0 million, or $(0.94) 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 $123.3 million as of July 31, 2023, 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.
