NOTE 5 — LICENSE AGREEMENTS

XOMA License Agreement

In December 2017, the Company entered into a license agreement (the “XOMA License Agreement”) with XOMA Corporation (“XOMA”), through its wholly-owned subsidiary, XOMA (US) LLC, pursuant to which XOMA granted an exclusive global license to the Company to develop and commercialize XOMA 358 (formerly X358, now RZ358) for all indications.

In January 2022, the Company was required to make a milestone payment under the XOMA License Agreement of $2.0 million that became due upon the dosing of the last patient in the Company’s Phase 2b Clinical Trial for RZ358. Upon the achievement of certain clinical and regulatory events under the XOMA License Agreement, the Company will be required to make additional milestone payments to XOMA up to $35.0 million. After the clinical and regulatory milestones, the Company will be required, upon the future commercialization of RZ358, to pay royalties to XOMA based on the net sales of the related products and additional milestone payments to XOMA up to $185.0 million related to annual net sales amounts. There have been no events that would result in any royalty payments owed under the XOMA License Agreement to date.

ActiveSite License Agreement

In August 2017, the Company entered into a Development and License Agreement (the “ActiveSite License Agreement”) with ActiveSite Pharmaceuticals, Inc. (“ActiveSite”) pursuant to which the Company acquired the rights to ActiveSite’s Plasma Kallikrein Inhibitor program (“PKI Portfolio”). The Company is initially using the PKI Portfolio to develop an oral PKI therapeutic for diabetic macular edema (RZ402) and may use the PKI Portfolio to develop other therapeutics for different indications. The ActiveSite License Agreement requires various milestone payments up to $46.5 million, if all milestones are achieved. The first milestone payment for $1.0 million was paid in December 2020 after clearance was received for an Initial Drug Application, or IND, filed with the U.S. Food and Drug Administration (“FDA”). The second milestone payment of $3.0 million was paid in February 2023 after dosing of the first patient in a Phase 2 clinical trial for RZ402. The next milestone payment of $5.0 million will be due upon dosing of the first patient in a Phase 3 clinical trial. The Company is also required to pay royalties equal to 2.0% of any sales of products that use the PKI Portfolio. There have been no events that would result in any royalty payments owed under the ActiveSite License Agreement to date.
