On August 23, 2021, iBio, Inc. (the “Company”) entered into a series of agreements with RubrYc Theraputics, Inc. (“RubrYc”) described in more detail below whereby in exchange for a $5 million investment in RubrYc, a potential further investment of $2.5 million, potential future milestones and royalties, the Company acquired:

RTX -003 Collaboration and License Agreement

On August 23, 2021, the Company entered into a Collaboration and License Agreement (the “RTX-003 License Agreement”) with RubrYc whereby the Company will further develop RubrYc’s immuno-oncology antibodies in its RTX-003 campaign. The RTX-003 antibodies were developed for their potential to bind to the CD25 protein without interfering with the IL-2 signaling pathway, thus supporting tumor immunity. The RTX-003 License Agreement provides that the Company is solely responsible for worldwide research and development activities for development of the RTX-003 antibodies for use in pharmaceutical products in all fields. Contingent upon receipt by RubrYc of funding of its Series A-2 preferred stock offering (see below), during the term of the RTX-003 License Agreement, RubrYc granted the Company an exclusive worldwide sublicensable royalty-bearing license under the patents controlled by RubrYc that cover the RTX-003 antibodies. The commercial license exclusively permits the Company to research, develop, make, have made, manufacture, use, distribute, sell, offer for sale, import, and export antibodies in RubrYc’s RTX-003 campaign.

Under the terms and conditions of the RTX-003 License Agreement, the Company agreed to use commercially reasonable efforts to develop and commercialize RTX-003 antibodies. If the Company fails to achieve certain timing milestones for starting GMP manufacturing and dosing human patients under an IND, the Company could be required to make a payment to RubrYc on the date the milestone is missed and on each anniversary of such date until the milestone is achieved, provided that the milestone was missed due to the Company’s failure to exercise commercially reasonable efforts.

Under the terms of the RTX-003 License Agreement, RubrYc is eligible to receive from the Company up to an aggregate of $15 million in clinical development and regulatory milestone payments for RTX-003 upon achievement of the following four clinical milestones:

RubrYc will also be entitled to receive royalties in the mid-single digits on net sales of RTX-003 antibodies, subject to adjustment under certain circumstances. Royalties are payable on a country-by-country basis until the latest to occur of: (i) the last-to-expire of specified patent rights in such country; (ii) expiration of marketing or regulatory exclusivity in such country; or (iii) ten (10) years after the first commercial sale of a product in such country, provided that no biosimilar product has been approved in such country.

If either the Company or RubrYc materially breaches the RTX-003 License Agreement and does not cure such breach within 60 days (or 30 days in the event of non-payment), the non-breaching party may terminate the RTX-003 License Agreement in its entirety. Either party may also terminate the RTX-003 License Agreement, effective immediately upon written notice, if the other party files for bankruptcy, is dissolved or has a receiver appointed for substantially all of its property. RubrYc may terminate the RTX-003 License Agreement if the Company or its sublicensees challenges the validity or enforceability of any of RubrYc’s Licensed Patents subject to certain exceptions. The Company may terminate the RTX-003 License Agreement in its entirety for any or no reason upon ninety (90) days’ written notice to RubrYc. In addition, if RubrYc is unable to complete a financing with proceeds of a certain agreed upon amount by a set time defined in the RTX-003 License Agreement, the Company may terminate the RTX-003 License Agreement upon written notice to RubrYc within thirty (30) days of the end of such period. Effective upon such termination, among other things, RubrYc shall assign to the Company exclusive ownership of the RTX-003, including all relevant intellectual property rights.

Collaboration, Option and License Agreement

On August 23, 2021, the Company entered into a Collaboration, Option and License Agreement (the “Collaboration Agreement”) with RubrYc, whereby the Company and RubrYc will collaborate for up to five years to discover and develop novel antibody therapeutics using RubrYc’s artificial intelligence discovery platform. Antibody targets for the collaboration may be agreed upon pursuant to written collaboration plans approved by a joint steering committee comprised of two representatives of each party. In addition, RubrYc has granted the Company an exclusive option to obtain a worldwide sublicensable commercial license with respect to each of the lead product candidates resulting from such collaboration programs (the “Selected Compounds”). The Company has agreed to pay RubrYc for each Selected Compound as it achieves various milestones in addition to royalties the Company would owe if it were commercialized.

Under the terms and conditions of the Collaboration Agreement, in the event the option is exercised by the Company, the Company has various diligence obligations including that it will use commercially reasonable efforts to (i) develop Selected Compounds for use in pharmaceutical products (the “Collaboration Products”); and (ii) commercialize the Collaboration Products. The Company is also required to meet a series of development milestones for each Collaboration Product. Failure to achieve the milestones will result in a payment to RubrYc on the date the milestone is missed and on each anniversary of such date until the milestone is achieved, provided that the milestone was missed due to the Company’s failure to exercise commercially reasonable efforts.

Under the terms of the Collaboration Agreement, RubrYc is eligible to receive from the Company up to an aggregate of $15 million in clinical development and regulatory milestone payments for each Collaboration Product that achieves the following:

RubrYc will also be entitled to receive tiered royalties ranging from low- to mid-single digits on net sales of Collaboration Products, subject to adjustment under certain circumstances. Royalties are payable on a country-by-country and collaboration product-by-collaboration product basis until the latest to occur of: (i) the last-to-expire of specified patent rights in such country; (ii) expiration of marketing or regulatory exclusivity in such country; or (iii) ten (10) years after the first commercial sale of a product in such country, provided that no biosimilar product has been approved in such country.

If either the Company or RubrYc materially breaches the Collaboration Agreement and does not cure such breach within 60 days (or 30 days in the event of non-payment), the non-breaching party may terminate the Agreement in its entirety. Either party may also terminate the Collaboration Agreement, effective immediately upon written notice, if the other party files for bankruptcy, is dissolved or has a receiver appointed for substantially all of its property. RubrYc may terminate the Collaboration Agreement if the Company, its affiliates or its sublicensees challenges the validity or enforceability of any of RubrYc’s patents covering any of the licensed compounds or products. The Company may terminate the Collaboration Agreement in its entirety, or with respect to a program, collaboration or Selected Compound for any or no reason upon ninety (90) days’ written notice to RubrYc.

In addition, if RubrYc is unable to complete a financing with proceeds of a certain agreed upon amount by a set time defined in the Collaboration Agreement, the Company may terminate the Collaboration Agreement upon written notice to RubrYc within thirty (30) days of the end of such period. Effective upon such termination, among other things, RubrYc shall assign to the Company exclusive ownership of the Collaboration Hit Candidates (as defined in the Collaboration Agreement) that are in the then-current (un-terminated) discovery collaboration plans, including all relevant intellectual property rights.

The Stock Purchase Agreement and Related Financing Documents

In connection with the entry into the Collaboration Agreement and RTX-003 License Agreement, the Company also entered into a Stock Purchase Agreement (“Stock Purchase Agreement”) with RubrYc whereby it purchased 1,909,563 shares of RubrYc’s Series A-2 preferred stock “Series A-2 Preferred”) for $5,000,000 and agreed to acquire an additional 954,782 shares of RubrYc’s Series A-2 Preferred for $2,500,000 in the event certain conditions set forth in the Stock Purchase Agreement are satisfied as of December 1, 2021.
