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 second fiscal quarter ended October 31, 2022.

“We made a very difficult decision this quarter in terminating our phase 2 KOMPLETE trial for KVD824, but the safety of patients is of utmost importance to our Company,” said Andrew Crockett, Chief Executive Officer of KalVista. “We remain committed to providing best-in-class oral treatments for the hereditary angioedema (HAE) community. We are particularly excited about our recent data for the orally disintegrating tablet (ODT) formulation of sebetralstat, which will enable people to take a dose without requiring chewing or swallowing. We are also pleased with the progress of our Phase 3 KONFIDENT clinical trial for sebetralstat, which remains on our enrollment target for data in the second half of 2023.”

Second Fiscal Quarter and Recent Business Highlights:

• Presented at both the Stifel 2022 Healthcare Conference and the Jefferies London Healthcare Conference.
• Reported new patient-focused data at the American College of Allergy Asthma & Immunology (ACAAI) 2022 meeting. The data showed the impact of attacks on mental health, daily activities, and quality of life in people living with HAE and demonstrated the treatment burden associated with on-demand parenteral HAE therapies.
• Announced data from a Phase 1 study of an ODT formulation of sebetralstat. KalVista believes this data supports further development of the formulation, which may have significant benefit for pediatric patients and those who experience difficulty swallowing.
• Published new sebetralstat data in both the Journal of Medicinal Chemistry and Xenobiotica, focusing on the medicinal chemistry KalVista conducted that led to the discovery of sebetralstat, and how sebetralstat’s absorption, metabolism, and excretion properties are beneficial for on-demand treatment of HAE attacks.
• Appointed Brian J. G. Pereira, M.D., as Chairman of the Board of Directors.
• Presented data at the 2022 HAEi Global Leadership Workshop with patient perspectives that support the use of the Patient Global Impression of Change (PGI-C) scale as a clinical endpoint to assess the efficacy of on-demand treatments for HAE attacks in the phase 3 KONFIDENT trial of sebetralstat.
• Announced the termination of the Phase 2 KOMPLETE study for KVD824, due to elevations in liver enzymes observed in patients during the trial. The Company intends to evaluate the unblinded data prior to making any final decisions as to the potential future development of KVD824.
• Enrollment is proceeding as expected for the Phase 3 KONFIDENT trial for sebetralstat, with data expected in the second half of 2023 and an NDA filing planned for the first half of 2024.

Second Fiscal Quarter Financial Results:

Revenue: No revenue was recognized for the three months ended October 31, 2022 or October 31, 2021.

R&D Expenses: Research and development expenses were $18.1 million for the three months ended October 31, 2022, compared to $17.5 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, increased preclinical spending, and increased personnel costs.

G&A Expenses: General and administrative expenses were $7.8 million for the three months ended October 31, 2022, compared to $6.1 million for the same period in the prior fiscal year. The increase in G&A expenses was primarily due to an increase in commercial planning expenses, professional fees, and to a lesser extent, increases in investor and public relations expenses.

Net Loss: Net loss was $22.3 million, or $(0.90) per weighted average basic and diluted share, for the three months ended October 31, 2022, compared to net loss of $19.7 million, or $(0.80) 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, primarily research and development.

Cash Position: Cash, cash equivalents and marketable securities were $122.3 million as of October 31, 2022, compared to $166.2 million as of April 30, 2022. The decrease in the net cash and marketable securities position was due to cash consumption from operating expenses.
