In September 2021, research conducted by MGH was published inCancer Nanotechnology, entitled “Radiolabeling and PET-MRI microdosing of the experimental cancer therapeutic, MN-anti-miR10b, demonstrates delivery to metastatic lesions in a murine model of metastatic breast cancer.” This paper reported on an MGH study using a radiolabeled derivative of TTX-MC138 (referred to in the paper as MN-anti-miR10b). In this study, TTX-MC138 was tagged with copper-64, or Cu-64. As a result, highly sensitive and specific quantitative determination of pharmacokinetics and biodistribution, as well as observation of delivery of the radiolabeled TTX-MC138 to metastases, was made in laboratory tests using noninvasive PET-MRI. The key results of the study suggest that when injected intravenously, TTX-MC138 accumulates in metastatic lesions. These results suggest that our TTX platform delivers its therapeutic candidate as intended and support clinical evaluation of TTX-MC138. In addition, the MGH investigation describes a microdosing PET-MRI approach to measure TTX-MC138 biodistribution in cancer patients and its delivery to clinical metastases. (Microdoses are minute, subpharmacologic doses of a test compound, not greater than 100 micrograms.) The capacity to carry out microdosing PET-MRI studies in patients under an exploratory IND, or eIND, application could be important because they have the potential to support additional clinical trials we may propose for FDA consideration. The research described in this paper, published by Dr. Zdravka Medarova, our Chief Scientific Officer and scientific co-founder, and others, describes what we believe is an effective approach to assessing delivery of TTX-MC138 in metastatic cancer patients. Since the PET-MRI technique is sensitive enough to determine the concentration of radiolabeled drug candidate in the sub-picomolar range, microgram quantities of the radiolabeled drug candidate are believed to be sufficient to perform such a study in humans. We believe this capability has significant advantages in the initial phases of drug development.

Because of the potential benefits from a microdose Phase 0 clinical trial, and reflecting the studies described inCancer Nanotechnology, our First-in-Human Phase 0 trial was designed to deliver a microdose of our therapeutic candidate. Preliminary results from the Phase 0 microdose trial suggest the validity of our TTX pipeline for drug delivery generally, potentially opening-up additional relevant RNA targets that have been previously undruggable.

Previous wording

On April 15, 2024, we announced that the FDA had completed its review of our IND application to conduct a Phase I/II clinical trial with our lead therapeutic candidate, TTX-MC138, and concluded that we may proceed with this clinical trial. The trial is a multicenter, open-label, dose-escalation and dose-expansion study in patients with advanced solid tumors. We commenced the trial in the third quarter 2024 at MD Anderson and three other clinical trial sites. The first stage of this trial, the Phase 1a, calls for administration of escalating therapeutic dose levels of our drug candidate to as many as six cohorts of three patients per cohort. The first cohort received the lowest therapeutic dose level. In October 2024, the trial’s Safety Review Committee (the “SRC”), approved commencing dosing of patients in the second cohort. Patients in the second and third cohorts have received dosing that is approximately double the level received by patients in each prior cohort. After three patients in each cohort received their initial dose of our drug candidate, the SRC assessed the data and determined that there were no drug-related serious adverse effects or dose limiting toxicities. The SRC approved commencement of dosing in the fourth cohort at a dosage that is approximately fifty percent higher than that administered in the third cohort. The SRC also approved enrollment of additional patients in Cohort 3 to build upon the safety profile of TTX-MC138. Preliminary data indicate no significant safety or dose limiting toxicities reported in Cohorts 1, 2, or 3 and PK and PD data from patients in Cohort 1 and Cohort 2 is consistent with preclinical results and results from our Phase 0 clinical trial. Key assessments in the clinical trial characterize the safety, pharmacokinetic, pharmacodynamic and anti-tumor activity of TTX-MC138 thus identifying a maximum tolerated dose (MTD) and ensuring the mechanism of action is on target. The trial also is exploring the effect of TTX-MC138 on biomarker expression, which may include miR-10b expression, and miR-10b downstream targets (RNA sequencing). Clinical assessments to further evaluate TTX-MC138 include clinical laboratory exams, CT scan assessments, and response assessments per RECIST criteria.

In January 2023, we made an initial payment of $250,000 to MD Anderson recorded as a Prepaid Expense pending such time as payments under the collaboration became due. As a result of changes at MD Anderson and the Company, we and MD Anderson agreed to amend the collaboration to continue our clinical trial currently underway at MD Anderson. Initial expenses of the clinical trial will be charged against the initial payment made to MD Anderson which for the three months ended March 31, 2025 and 2024, were $81,561 and $0, respectively.

Current wording

On July 29, 2022, we signed a five-year strategic collaboration agreement with The University of Texas M. D. Anderson Cancer Center (“MD Anderson”). Under the collaboration, we anticipated making certain expenditures with respect to Phase I and Phase II clinical trials in part through MD Anderson as a clinical site. MD Anderson was also expected to provide preclinical work under the collaboration. The details of clinical and preclinical work were to be mutually agreed by the parties prior to commencing work. We had agreed to fund up to $10 million over the term of the collaboration. In January 2023, we made an initial payment of $250,000 to MD Anderson recorded as a Prepaid Expense pending such time as payments under the collaboration became due. As a result of changes at MD Anderson and the Company, we and MD Anderson agreed to amend the collaboration to continue our clinical trial currently underway at MD Anderson.

Previous wording

We rely to a significant extent on third-parties to conduct preclinical studies, provide materials, and to provide clinical trial services, including trial conduct, data management, statistical analysis and electronic compilation. At the end of each reporting period, we compare payments made to each service provider to the estimated progress towards completion of the related project. Factors that we consider in preparing these estimates include materials delivered or services provided, milestones achieved, the number of patients enrolled in studies, and other criteria related to the efforts of these vendors. These estimates are subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, we record net prepaid or accrued expenses related to these costs.

The estimating process involves reviewing open contracts and purchase orders, communicating with our relevant personnel to identify services that have been performed on our behalf or deliveries of materials made to us, and estimating the level of service performed and the associated cost incurred for those services when we have not yet been invoiced or otherwise notified of actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule, or when contractual milestones are met; however, some require advance payments. As of each balance sheet date, we make estimates of our accrued expenses based on facts and circumstances

Previous wording

The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust the accrual or the prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period.

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrants’ specific terms and applicable authoritative guidance in ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), and ASC 815 “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to our own ordinary shares and whether warrant holders could potentially require “net cash settlement” in a circumstance outside of our control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end-date while the warrants are outstanding.

For issued or modified warrants that meet all the criteria for equity classification, the warrants are required to be recorded as a component of equity at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded as liabilities at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of warrants classified as liabilities are recognized as a non-cash gain or loss on our statements of operations.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards by delaying adoption of these standards until they would apply to private companies. We have elected to use the extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date on which we (i) are no longer an emerging growth company and (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of effective dates applicable to public companies.
