KalVista Pharmaceuticals, Inc. (NASDAQ:KALV) ("KalVista"), today announced the closing of a synthetic royalty financing agreement with DRI Healthcare Trust ("DRI") for up to $179 million, comprised of a $100 million upfront payment, a one-time $22 million optional payment upon U.S. product approval, and up to $57 million in a sales-based milestone payment. The proceeds of this transaction will be used to fund the commercialization of sebetralstat, which, if approved, is expected to be the first approved oral on-demand therapy to treat hereditary angioedema ("HAE"). KalVista has a New Drug Application for sebetralstat under review by the U.S. Food and Drug Administration (the "FDA") with a Prescription Drug User Free Act ("PDUFA") target action date of June 17, 2025.

DRI has also indicated an interest in investing up to $5 million in KalVista's common stock in a private placement transaction. However, this indication of interest is not binding agreement or commitment to purchase KalVista's common stock and DRI may decide to purchase more, less or no shares of KalVista's common stock and KalVista may decide to not sell shares of its common stock to DRI.

"This financing arrangement is a pivotal step for KalVista, enabling us to continue building a global commercial organization ahead of the potential U.S. launch of sebetralstat in June 2025," said Ben Palleiko, Chief Executive Officer of KalVista. "Moving forward, we are well-positioned to achieve long-term sustainable growth as we focus on delivering a potentially transformative treatment for people living with HAE. We appreciate DRI's confidence in KalVista and sebetralstat to make this their first pre-approval investment."

"Our royalty investment reflects DRI's research-driven belief that sebetralstat has the potential to be the foundational treatment for all people living with HAE. We are excited to support the KalVista team's continued transformation toward a commercial organization at this important stage," said Navin Jacob, Chief Investment Officer of DRI.

"Acquiring a synthetic royalty on such a high-quality asset like sebetralstat showcases DRI's willingness to develop partnerships with companies like KalVista who are seeking to meaningfully improve patients' lives," said Ali Hedayat, Acting Chief Executive Officer of DRI.

Synthetic Royalty Financing Terms

Under the terms of the synthetic royalty financing agreement, KalVista will immediately receive $100 million and be obligated to pay DRI a tiered royalty of 5.00% of annual global net sales up to and including $500 million, 1.10% of annual global net sales above $500 million and up to and including $750 million, and 0.25% of annual global net sales above $750 million. KalVista is entitled to a potential one-time sales-based milestone payment of $50 million if annual global net sales of sebetralstat meet or exceed $550 million in any calendar year before January 1, 2031.

If sebetralstat is approved prior to October 1, 2025, KalVista will have the option to receive a one-time payment of $22 million. If KalVista chooses to receive this optional payment, the royalty rate on net sales up to and including $500 million will increase from 5.00% to 6.00%, and the sales-based milestone amount will increase from $50 million to $57 million.
