License Option Agreement and License Agreement with CWRU

On July 1, 2020, we signed a License Option Agreement with CWRU, granting the Company the exclusive right to license certain technology covering an immunotherapy platform technology to treat and prevent cancer in humans and for veterinary use, including MIE-101, our lead clinical candidate. Under the License Option Agreement, CWRU granted us the exclusive option for a period of two (2) years to negotiate and enter into a license agreement with CWRU, provided that we meet certain diligence milestones.

Under the License Option Agreement, we issued CWRU 70,000 shares of Class B Common Stock at the fair market value of $7 on the date of issuance. On August 21, 2020, the Class B Common Stock was exchanged for shares of Series B Preferred.

On May 4, 2022, we exercised our rights under the License Option Agreement and entered into a license agreement with CWRU (“License Agreement”). Pursuant to the terms of the License Agreement, we agreed to pay CWRU for each licensed product used in human applications (i) development milestones of up to $1.8 million in aggregate dependent upon the progress of clinical trials, regulatory approvals, and initiation of product launch, (ii) tiered royalty on net sales beginning in the mid-single digits, (iii) annual minimum royalty of $10,000 beginning on the second anniversary date of the Agreement with the minimum amount rising based on net sales of the licensed product, and (iv) a declining percentage of all non-royalty sublicensing income based on the escalating stage of development upon a sublicensing event, if applicable. In addition, we agreed to pay CWRU for each licensed product used in veterinarian applications (i) a tiered royalty on net sales beginning in the low single digits and (ii) a declining percentage of all non-royalty sublicensing income based on the escalating stage of development upon a sublicensing event, if applicable.

In addition, we are responsible for the reimbursement of all past, current and future patent fees incurred by CWRU under the License Agreement. During the three months ended March 31, 2025 and 2024, we did not incur any patent legal fees associated with the License Agreement.

Furthermore, we agreed to reimburse CWRU for all intellectual property fees incurred since inception of the portfolio through the date of the License Agreement in the amount of approximately $303,000 (included in Accrued expenses and other in the accompanying condensed consolidated balance sheets) in four (4) equal quarterly installments beginning upon the sooner of (i) August 31, 2022 or (ii) upon the Company closing a financing in the amount of $5 million or more. Due to our limited cash position, as of December 31, 2024, we had not paid any amounts owed to CWRU and we continued to seek additional time to raise sufficient capital in order to pay amounts due to CWRU. On March 22, 2024, we received a notice of termination from CWRU to terminate the License Agreement effective on the notice date. As of March 31, 2025 and December 31, 2024, we have accrued $406,973 in accrued patent fees under the License Agreement.

License Agreements with University of California San Diego (“UC San Diego”)

During July 2021, we licensed the exclusive rights from UC San Diego to develop and commercialize technology that involves the loading of immuno-stimulatory molecules into plant virus protein nanoparticles.
