– Recent KVD900 Phase 2 Clinical Trial Results Statistically and Clinically Significant –

– IND Submitted for Oral Prophylactic HAE Treatment Candidate KVD824; Phase 2 Expected to Initiate in Q2 2021 –

– Following Upsized Public Offering, Funded to KVD900 NDA Filing –

CAMBRIDGE, Mass. & SALISBURY, England–(BUSINESS WIRE)–$KALV–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 third fiscal quarter ended January 31, 2021.

“We are making excellent progress in our commitment to providing those with hereditary angioedema a complete set of oral options to manage their disease. The data announced last month for KVD900 as an oral on-demand therapy were overwhelmingly positive and show that patients don’t have to compromise on efficacy or rely on injectables. We view this data as validation of our work in oral plasma kallikrein inhibition, which also includes KVD824 as a development candidate for an oral prophylactic treatment for HAE,” said Andrew Crockett, Chief Executive Officer of KalVista. “Our next step is to meet with regulatory agencies to finalize the Phase 3 program for KVD900 while we push ahead with preparations to be ready to begin that trial as quickly as possible. We have also filed the IND for a Phase 2 clinical trial of KVD824 and expect to initiate that trial in the second quarter of 2021. The closing of our recent upsized financing puts us in a position to execute on plans across our oral HAE franchise, thanks to a cash balance sufficient to get us to the KVD900 NDA filing.”

Third Fiscal Quarter and Recent Business Highlights:

• Reported positive results for KVD900 in a Phase 2 clinical trial demonstrating statistically and clinically significant responses across primary and secondary endpoints as an oral on-demand treatment for HAE attacks. The trial met its primary endpoint comparing the time to use of conventional attack treatment within 12 hours on KVD900 versus placebo (p=0.0010) with rates of use at 12 hours of 15.1% following treatment with KVD900 versus 30.2% after placebo. The trial also met all secondary endpoints: reduced worsening of attacks (p<0.0001; PGI-S or use of rescue) and reduced time to onset of symptom relief measured using both patient’s global impression of change (PGI-C) (p<0.0001) and visual analogue scale (VAS) (p<0.0001). The trial included 126 administrations of KVD900 and 55 of placebo. During the uncontrolled, open label phase, 5 of 68 patients dosed reported 8 adverse events suspected to be related to treatment. During the randomized, placebo-controlled phase, 5 patients reported adverse events suspected to be treatment-related (3 of 58 dosed with KVD900 and 2 of 55 dosed with placebo).
• Closed an upsized public offering of common stock and full exercise of the underwriters’ options to purchase additional shares. The gross proceeds, before deducting the underwriting discounts and commissions and other offering expenses were approximately $222.5 million based on 6,181,250 shares at a price to the public of $36.00 per share.

Third Fiscal Quarter Financial Results:

• Revenue: No revenue was recognized for the three months ended January 31, 2021, compared to $1.6 million for the same period in the prior fiscal year. The decrease of $1.6 million was due to the expiration of the Merck Option Agreement in February 2020. No future revenue remains to be recognized under this agreement.
• R&D Expenses: Research and development expenses were $9.1 million for the three months ended January 31, 2021, compared to $11.2 million for the same period in the prior fiscal year. The decrease in expenses during the quarter primarily reflect a decrease in spending on KVD001, which concluded a Phase 2 clinical trial in December 2019, a decrease in spending on KVD900, and a decrease in spending on preclinical activities. These decreases were somewhat offset by increased spending related to the development of KVD824.
• G&A Expenses: General and administrative expenses were $3.6 million for the three months ended January 31, 2021, compared to $3.1 million for the same period in the prior fiscal year. The $0.5 million increase in expenses primarily reflects an increase in employee related and commercial development expenses.
• Net Loss: Net loss was $10.1 million, or $(0.56) per weighted average basic and diluted share, for the three months ended January 31, 2021, compared to net loss of $9.3 million, or $(0.52) 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 in the three months ended January 31, 2021 compared to the same period in the prior fiscal year was primarily due to decreases in revenue and other income in the three months ended January 31, 2021, somewhat offset by the decrease in research and development expenses.
• Cash: Cash, cash equivalents and marketable securities were $50.3 million as of January 31, 2021, compared to $67.7 million as of April 30, 2020. The decrease in net cash position was due to increased spending, primarily on research and development activities.
