Takeda Pharmaceutical Co. Ltd. ( together with its wholly-owned subsidiaries, “Takeda”)

The Company was a party to an exclusive research, development and license agreement with Takeda related to the development of a novel series of polysialylated blood coagulation factors. This collaboration with Takeda relied on the Company’s PolyXen technology to conjugate PSA with therapeutic blood-clotting factors, with the goal of improving the pharmacokinetic profile and extending the active half-life of these biologic molecules. The agreement granted Takeda a worldwide, exclusive, royalty-bearing license to the Company’s PSA patented and proprietary technology in combination with Takeda’s proprietary molecules designed for the treatment of blood and bleeding disorders. There are no active projects under the exclusive research, development and license agreement, and the parties mutually terminated the agreement in August 2021.

In October 2017, the Company granted to Takeda the right to grant a non-exclusive sublicense to certain patents related to the Company’s PolyXen technology that were previously exclusively licensed to Takeda in connection with products related to the treatment of blood and bleeding disorders. Royalty payments of approximately $1.2 million and $0.4 million were recorded as revenue by the Company during the years ended December 31, 2021 and 2020, respectively, and are based on single digit royalties on net sales of certain covered products. The Company’s policy is to recognize royalty payments as revenue when they are reliably measurable, which is upon receipt of reports from Takeda. The Company receives these reports in the quarter subsequent to the actual sublicensee sales. At the time the revenue was received, there were no remaining performance obligations and all other revenue recognition criteria were met. The termination of the exclusive research, development and license agreement had no impact on the Company’s non-exclusive sublicense agreement and the royalties being generated.

Scripps Research

On May 15, 2020, the Company and Scripps Research entered into a Research Funding and Option Agreement (the “Scripps Agreement”), pursuant to which the Company has agreed to provide Scripps Research an aggregate of up to $3.0 million to fund research relating to advancing the pre-clinical development of XCART. The research funding is payable by the Company to Scripps Research on a quarterly basis in accordance with a negotiated budget, which provides for an initial payment of approximately $300,000 on the date of the Scripps Agreement and subsequent quarterly payments of approximately $300,000 over a 27-month period. Under the Scripps Agreement, Scripps Research has granted the Company a license within the Field (as defined in the Scripps Agreement) to any Patent Rights or Technology (as defined in the Scripps Agreement) under the terms of that certain license agreement with Scripps Research, dated February 25, 2019, assigned to the Company on March 1, 2019. Additionally, the Company has the option to acquire a worldwide exclusive license to Scripps Research’s rights in the Technology or Patent Rights not already licensed to the Company, as well as a non-exclusive, royalty-free, non-transferrable license to make and use Scripps Research Technology (as defined in the Scripps Agreement) solely for the Company’s internal research purposes during the performance of the research program contemplated by the Scripps Agreement. The Company has paid $2.1 million to Scripps Research under this agreement through December 31, 2021. As of December 31, 2021, and December 31, 2020, approximately $0.2 million has been recognized as an advance payment under this agreement and is included in prepaid expenses and other current assets.

In addition to its common stock ownership, Pharmsynthez owns approximately 1.5 million shares of our outstanding Series B Preferred Stock (as defined in Note 10, Stockholders’ Equity), and all of our issued and outstanding Series A Preferred Stock (as defined in Note 10, Stockholders’ Equity) through SynBio.

During the third quarter of 2019, the Company entered into a Sponsored Research Agreement with Pharmsynthez (the “SRA”) related to experiments identified by the Company to support its efforts for initial tech transfer of the XCART methods to a future academic collaborator. Under the agreement, the Company made a $350,000 payment to Pharmsynthez during the third quarter of 2019, which was refundable on a pro rata basis if the project is terminated prematurely as a result of Pharmsynthez failing to perform the work. On June 12, 2020, the Company and Pharmsynthez entered into a Master Services Agreement (“MSA”) to advance the development of the Company’s XCART technology for B-cell malignancies. The MSA terminated and superseded the SRA. The Company expensed approximately $0.1 million and $0.2 million related to work performed under these agreements during the years ended December 31, 2021 and 2020, respectively. There were no amounts recorded on the consolidated balance sheet as of December 31, 2021. As of December 31, 2020, approximately $25,000 was recorded as an advanced payment and included in prepaid expenses and other assets on the consolidated balance sheet.

Under the MSA, Pharmsynthez agreed to provide services pursuant to work orders agreed upon by the parties from time to time, which services include, but are not limited to, acting as the Company’s primary contract research organization to assist in managing collaborations with multiple academic institutions in Russia and Belarus. The Company is required to pay reasonable fees, expenses and pass-through costs incurred by Pharmsynthez in providing the services in accordance with a budget and payment terms set forth in each work order. Additionally, in the event that a work order provides for milestone payments, the Company is required to make such payments to Pharmsynthez, or third party service providers designated by Pharmsynthez, in accordance with the terms set forth in the work order, which milestone payments may be made, at the sole discretion of the Company, in cash or shares of the Company’s common stock.

The Company and Pharmsynthez executed a work order on June 12, 2020 (the “Work Order”) under the MSA pursuant to which Pharmsynthez agreed to conduct a Stage 1 study of the Company’s XCART technology under the research program as set forth in the Work Order. The activities to be performed under the Work Order were expected to take approximately 20 months unless earlier terminated in accordance with the MSA. Under the terms of the Work Order, the Company paid Pharmsynthez $51,000 as an initial payment for trial startup costs, which amount was credited against the amounts paid under the SRA. The Work Order provided for additional pass-through costs to be invoiced by Pharmsynthez upon execution of contracts with third party sites, which were to be further credited against the SRA. Through December 31, 2021, all costs incurred under the MSA were credited against the amounts paid under the SRA. Additionally, the Work Order provided for milestone payments of up to an aggregate of $1,050,000, or, in the Company’s sole discretion, up to an aggregate of 1,000,000 shares of the Company’s common stock, to be paid or issued, as applicable, by the Company upon achievement of milestones associated with completion of early stages of the research program as set forth in the Work Order. As of December 31, 2021, approximately $0.1 million of milestone payments had been made and no further milestone payments are expected.

On October 12, 2021, the Company entered into Amendment Number One to the MSA (the “MSA Amendment”) with Pharmsynthez to, among other things, terminate all work orders under the MSA. As a result, no further services were to be performed under the Work Order and any additional services will be covered by new work orders. In exchange, the Company entered into a new work order (the “Second Work Order”) simultaneously with the MSA Amendment. Under the terms of the Second Work Order, Pharmsynthez shall provide certain enumerated services to support the Company’s development of its XCART technology upon the written request of the Company, which work may be requested by the Company from time to time.

Pursuant to the MSA Amendment and Second Work Order, upon entry into the Second Work Order, the Company made a one-time $40,000 payment to Pharmsynthez, of which $21,000 was a one-time payment in full for all money and other compensation owed by the Company under the Work Order, and the remaining $19,000 will be creditable against any out of pocket costs and expenses incurred by Pharmsynthez on behalf of the Company pursuant to any new work orders initiated after the effective date of the MSA Amendment, including the Second Work Order.

In August 2011, SynBio, a wholly-owned subsidiary of Pharmsynthez, and the Company entered into a stock subscription and collaborative development agreement (the “Co-Development Agreement”). The Company granted an exclusive license to SynBio to develop, market and commercialize certain drug candidates utilizing molecules based on SynBio’s technology and the Company’s proprietary technologies (PolyXen, OncoHist and ImuXen) in Russia and CIS, collectively referred to herein as the SynBio Market. In return, SynBio granted an exclusive license to the Company to use the preclinical and clinical data generated by SynBio in certain agreed products and to engage in the development of commercial candidates in any territory outside of the SynBio Market.

SynBio and the Company are each responsible for funding and conducting their own research and clinical development activities. There are no milestone or other research-related payments provided for under the Co-Development Agreement other than fees for the supply of each company’s respective research supplies based on their technology, which, when provided, are due to mutual convenience and not representative of an ongoing or recurring obligation to supply research supplies. Serum Institute of India Limited (“Serum Institute”) has agreed to directly provide the research supplies to SynBio, where the Company is not liable for any failure to supply the research supplies as a result of any act or fault of Serum Institute. Upon successful commercialization of any resultant products, the Company is entitled to receive a 10% royalty on sales in certain territories and pay royalties to SynBio for sales outside those certain territories, subject to the terms of the Co-Development Agreement. Effective December 20, 2021, SynBio assigned the Co-Development Agreement to Pharmsynthez.

Through December 31, 2021, Pharmsynthez continued to engage in research and development activities with no resultant commercial products. In December 2020, Pharmsynthez reported positive data from its Phase 3 clinical study of Epolong, a treatment for anemia in patients with chronic kidney disease leveraging the Company’s PolyXen technology. In February 2021, Pharmsynthez reported in a press release that it had started the registration phase of Epolong by filing a registration dossier to obtain approval in Russia. Pharmsynthez had reported in its press release that it expected that the Russian stage of registration activities would be completed in 2021 and that it would be able to start production of the product as early as the first quarter of 2022. Pharmsynthez has not informed the Company that the registration process has been completed or that production of the product has commenced. The Company did not recognize revenue in connection with the Co-Development Agreement during the years ended December 31, 2021 and 2020. 0
