KalVista Pharmaceuticals Reports First Fiscal Quarter Results

– FDA End-of-Phase 2 Meeting for KVD900 Oral HAE Phase 3 Program Scheduled for This Month –

– KVD824 Phase 2 KOMPLETE Clinical Trial Enrolling –

Cambridge, MA and Salisbury, England, September 9, 2021 – KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of small molecule protease inhibitors, today provided an operational update and released financial results for the first fiscal quarter ended July 31, 2021.

“We have made excellent progress in the rollout of our Phase 2 KOMPLETE clinical trial for KVD824,” said Andrew Crockett, Chief Executive Officer of KalVista. “Site initiations are underway, and patients are being enrolled in the trial to evaluate KVD824 as a potential oral prophylactic treatment for HAE. We will be having an end-of-Phase 2 meeting with the FDA later this month regarding KVD900, our oral on-demand candidate for treatment of HAE attacks and are ready to initiate the Phase 3 study quickly afterwards. We look forward to advancing both of these compounds as we continue with our strategy of bringing a full spectrum of oral treatment options to HAE patients.”

First Fiscal Quarter and Recent Business Highlights:

• Presented Phase 2 data for KVD900 in late-breaking session at European Academy of Allergy and Clinical Immunology (EAACI) Congress. The data showed that a single on-demand treatment with orally administered KVD900 significantly slows progression and accelerates resolution of attacks in patients with hereditary angioedema (HAE). KalVista also presented four other posters at EAACI related to the HAE clinical landscape and unmet needs, as well as preclinical data from other oral molecules.

• Scheduled an end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to review the proposed development plans for KVD900, KalVista’s oral on-demand candidate for treatment of HAE attacks, expected to take place in September 2021. KVD900 also received Orphan Drug Designation from the FDA.

• Presented data at the International Society on Thrombosis and Haemostasis (ISTH) Virtual Congress showcasing small molecule Factor XIIa inhibitor research.

• Provided a progress update on the KVD824 Phase 2 KOMPLETE Clinical Trial. KVD824 is in development for oral prophylactic treatment of HAE. Regulatory submissions have been approved in Canada, Australia, and the UK with patient enrollment now underway. KalVista also submitted a response to the clinical hold related to the U.S. Investigational New Drug (IND) filing for KVD824 and is prepared to initiate the study in the U.S. upon clearance from the FDA.

• Presented KVD001 data at American Chemical Society (ACS) Meeting.

First Fiscal Quarter Financial Results:

• Revenue: No revenue was recognized for the three months ended July 31, 2021 or July 31, 2020.

• R&D Expenses: Research and development expenses were $13.7 million for the three months ended July 31, 2021, compared to $11.2 million for the same period in the prior fiscal year. The increase in R&D expenses during the quarter primarily reflects increased preclinical spending and the ongoing clinical trial for KVD824, offset by a decrease in spending on KVD900 and KVD001 due to their concluded Phase 2 clinical trials in February 2021 and December 2019, respectively.

• G&A Expenses: General and administrative expenses were $5.9 million for the three months ended July 31, 2021, compared to $3.3 million for the same period in the prior fiscal year. The increase in G&A expenses was primarily due to an increase in compensation related expenses and to a lesser extent, increases in commercial planning expenses, professional fees, and other administrative costs.

• Net Loss: Net loss was $16.1 million, or $(0.66) per weighted average basic and diluted share, for the three months ended July 31, 2021, compared to net loss of $10.8 million, or $(0.61) 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 $230.6 million as of July 31, 2021, compared to $248.9 million as of April 30, 2021. The decrease in the net cash position was due to increased operating expenses.
