ITEM 1. BUSINESS.
Our Company
The Company is a Delaware corporation initially formed in March 2022 as Unite Acquisition 1 Corp. Effective February 11, 2025, Unite Acquisition’s wholly-owned subsidiary, Merger Sub, merged with and into Private Adaptin, a Delaware corporation. Private Adaptin was the surviving corporation in the Merger and became Unite Acquisition’s wholly-owned subsidiary, renamed as Adaptin Operating Co. At the same time, Unite Acquisition changed its name to Adaptin Bio, Inc.
The Company’s website address is www.adaptinbio.com and we can be contacted at info@adaptinbio.com. Information contained on, or that can be accessed through, our website is not a part of this Report.
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act, or the JOBS Act, and, for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies, including:
● not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act;
● reduced disclosure obligations regarding executive compensation in our periodic reports and annual report on Form 10-K; and
● exemptions from the requirements of holding non-binding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved.
Our status as an emerging growth company will end upon the earlier of: (a) the fifth anniversary of the first sale of our common equity securities pursuant to an effective registration statement; (b) the last day of the fiscal year in which we have more than $1.235 billion in annual gross revenues; (c) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; and (d) the date on which we have issued, in any three-year period, more than $1 billion in non-convertible debt securities.
Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to avail ourselves of this provision of the JOBS Act. As a result, we will not be subject to new or revised accounting standards at the same time as other public companies that are not emerging growth companies. Therefore, our consolidated financial statements may not be comparable to those of companies that comply with new or revised accounting pronouncements as of public company effective dates.
We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a “smaller reporting company” even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting Common Stock held by non-affiliates is less than $250 million measured on the last business day of our second fiscal quarter, or our annual revenues is less than $100 million during the most recently completed fiscal year and our voting and non-voting Common Stock held by non-affiliates is less than $700 million measured on the last business day of our second fiscal quarter.
Business Overview
Adaptin is a biopharmaceutical company pioneering a transformational approach to enhance the transfer of therapeutics into the brain, facilitating the treatment of brain cancers and other unmet medical conditions. The Company’s proprietary technology harnesses the human immune system’s ability to target, recognize, destroy or deliver therapeutics to specific cells, including cancer cells. Our mission is to be the global leader and pioneer of this new treatment paradigm, integrating recombinant technology, gene therapy and cell therapy to address the challenges of targeting and delivering effective therapies, including to the brain for cancer and other central nervous system (“CNS”) indications.
The cause(s), or etiology, of many diseases can be addressed in part through manipulation of engineered cells. We view targeted manipulation of the human immune system, together with recombinant technology and/or gene therapy, as a therapeutically disruptive transformation in the way we treat brain and other diseases. Our lead product candidate has been recently accepted under an investigator-led IND to begin first-in-human studies in brain cancer. Assuming success of those studies, our experienced group of scientists and business leaders intend to develop our proprietary in vivo and ex vivo technology platforms to revolutionize treatment across a broad array of other therapeutic areas with unmet treatment needs, including CNS disorders, autoimmune disease and cardiovascular diseases, among others. Pursuing other therapeutic areas will likely require us to either raise a significant amount of additional capital or to engage in strategic transactions such as spin-offs or out-licenses. Our goal is to complete preclinical studies on additional product candidates and file multiple investigational new drug applications (each, an “IND”) in 2026, if not earlier.
Adaptin’s novel technology was originally developed by researchers in the Department of Neurosurgery at Duke University, led by Dr. John H. Sampson, the prior Robert H. and Gloria Wilkins Distinguished Professor and Chair of the Department of Neurosurgery and currently the Dean and Vice Chancellor at the University of Colorado School of Medicine. The group recognized that adoptive transfer of specifically activated functional human immune cells significantly increases the “hitchhiking” and intracerebral accumulation of macromolecules that are bound to their surface. While circulating naïve T cells do not typically penetrate the CNS, activated T cells are known to traffic frequently past the blood brain barrier (“BBB”) and perform routine immune surveillance in the CNS. Adaptin and its collaborators at Duke University are taking advantage of this CNS trafficking to enhance the localization of macromolecules and other agents to the CNS for cancer and other CNS disorders.
Adaptin is closely working with researchers at Duke University to translate preclinical proof of concept data of its first proprietary platform technology called BRiTE (Brain Bispecific T-cell Engager) into human clinical trials. BRiTE focuses on the transport of difficult to deliver T cell targeting agents to tumor tissue, including in the immunoprivileged brain and overcoming the challenges with other immunotherapeutic approaches. BRiTE is a translatable method to specifically target malignant glioma using a tumor-specific, fully human bispecific antibody that redirects patients’ own T cells to recognize and destroy tumor cells.
The first application of Adaptin’s technology is APTN-101, a proprietary epidermal growth factor receptor variant III, or EGFRVIII, BRiTE in order to eliminate malignant glioma tumors in a variety of aggressive preclinical tumor models where the tumor is implanted behind the BBB in the CNS (i.e., orthotopic). We designed APTN-101 to specifically redirect T cells against tumors expressing a well-characterized, mutated form of epidermal growth factor receptors (“EGFRs”) known as EGFRVIII, on a number of tumor types, including glioblastoma, breast and lung cancer. Because EGFRVIII is exclusively expressed on tumor cells, but not normal healthy cells, we believe it represents an ideal target for immunotherapy. We have made significant progress towards first-in-human clinical studies, including:
● A pre-IND meeting with the FDA outlining a clear path to filing an IND;
● Completion of single-dose IND-enabling preclinical studies;
● Submission in April 2023 of an IND for an investigator-initiated, single-dose clinical trial, and its acceptance in May 2023 by the FDA; and
● Manufacturing of APTN-101 in more than sufficient quantities for Phase 1 trials.
We also expect to expand our proprietary platform to other targets and indications. The Company is exploring several external opportunities to continue to advance and expand the product pipeline.
Strategy
Our goal is to become a leading biopharmaceutical company focused on the transfer of drugs across barriers and to targeted tissues, including the brain and CNS, to transform current treatment paradigms for patients and address unmet medical needs. The critical components of our strategy are as follows:
● Advance the development of APTN-101 for the treatment of glioblastoma. The FDA’s acceptance in May 2023 of the IND for APTN-101 for the treatment of glioblastoma sets the stage for first-in-human clinical trials.
● Advance preclinical development of APTN-101 to support one or more additional INDs for additional kinds of cancer. We have designed APTN-101 to incorporate EGFRvIII, which is expressed on a number of tumor types, including breast and lung cancer (with or without brain metastases), so we are considering pre-clinical work to support INDs for these indications to be filed in 2026, if not earlier.
● Design and advance other early-stage drug product candidates for undisclosed rare and unmet needs. Because our proprietary technology enables drugs to cross barriers and target tissues, including the brain, we believe it has numerous potential applications in areas of unmet medical need. We are evaluating which of those indications would be most strategic to pursue in the near-term, and plan to initiate one or more preclinical studies in 2025 to support the filing of future INDs.
● Acquire, in-license or develop complementary delivery technologies that will allow us to produce BRiTE compounds or manipulate and activate immune cells in vivo. We continually evaluate technologies that will further enhance therapeutic effect, improve safety and manufacturability, or reduce costs of our products.
● Acquire targeted clinical compounds for conditions with unmet needs where our technology could be transformative. We continually evaluate development and in-licensing opportunities and may acquire clinical compounds for conditions with unmet medical needs where our technology’s ability to cross barriers and target specific tissues, including the brain, could be transformative of the treatment paradigm.
● Pursue a capital-efficient commercialization strategy. For products with smaller and/or orphan patient populations, our plan is to build an infrastructure to commercialize our drug products within the United Sates. Drawing upon our experience in commercializing specialty pharmaceutical products, we aim to build a specialized yet efficient infrastructure that will support the entire commercialization continuum, including stakeholder education, treatment decision and initiation, and product access throughout the patient journey. In addition, we plan to seek established companies to commercialize our drug products for larger addressable markets and outside of the United States.
● Leverage, protect and enhance our intellectual property portfolio and secure patents for additional products and indications. We intend to expand our intellectual property, grounded in securing composition of matter and method of use patents for new products and indications. We plan to enhance the intellectual property portfolio further through learnings from ongoing preclinical studies, clinical trials and manufacturing processes.
● Outsource capital-intensive operations. We plan to continue to outsource capital-intensive operations, including most clinical development and all manufacturing operations of our product candidates, and to facilitate the rapid development of our pipeline by using high quality specialist vendors and consultants in a capital efficient manner.
Glioblastoma
Background
Glioblastoma multiforme (“GBM”), the highest grade (World Health Organization (“WHO”) grade IV) astrocytoma, is the most common and malignant brain tumor, accounting for about 50% of all gliomas and 12%-15% of all brain tumors. GBM tumor cells, which arise from stem cells or immature astrocytes due to genetic abnormalities, grow rapidly and disseminate in the brain. In addition, GBM cells can invade the intracranial blood vessels to areas away from the tumor core.
Although glioblastoma can happen anywhere in the brain, it usually forms in the frontal lobe and the temporal lobe. Glioblastoma rarely occurs in the brain stem or spinal cord. As glioblastoma grows, it spreads into the surrounding brain. This makes it difficult to remove the entire tumor with surgery. Although radiation therapy and chemotherapy can reach the tumors, glioblastoma cells can survive and regrow. Glioblastoma is very challenging to treat due to tumor-specific features, such as its rapid growth rate, the poor function of the immune system cells within the tumor, and inherent resistance of the tumor cells to many types of treatments.
There is no direct risk factor associated with most cases of glioblastoma. Certain rare genetic diseases, such as Li-Fraumeni and Lynch syndrome, are associated with gliomas. However, these affect only a small portion of patients with glioblastoma. Besides genetic syndromes, the only well-established risk factor is prior exposure to ionizing radiation that is used to treat certain head and neck cancers.
Brain tumor symptoms vary and depend on the tumor location. The most common glioblastoma symptoms are headaches, seizures, and progressively worsening numbness or weakness. Headaches with red flag symptoms warrant a trip to the doctor for a neurologic evaluation. Red flag symptoms include waking up due to pain, worsening pain on changing position, and continuous pain not relieved with over-the-counter headache medications.
Neurologic imaging with an MRI of the brain is often the first step in diagnosis. Brain imaging showing contrast-enhancing masses can be suggestive of glioblastoma. Most cases can be definitively diagnosed after surgery through histological testing. This takes place when a neuropathologist examines tissue or cells under a microscope to help confirm a glioblastoma diagnosis.
Incidence and Mortality
In the United States, the average annual age-adjusted incidence of glioblastoma is 3.2 per 100,000 population (or about 12,000 patients annually) with an average age of 64 at diagnosis. Glioblastoma is 1.6 times more common in males compared with females and 2.0 times higher in Caucasians compared to African Americans, with lower incidence in Asians and American Indians. Globally, glioblastoma incidence is highest in North America, Australia, and Northern and Western Europe. Veterans who served in Iraq or Afghanistan are 26% more likely to develop glioblastoma, according to the U.S. Department of Veterans Affairs and National Institutes of Health data, likely due to environmental exposures. Malignant primary brain tumors are the most frequent cause of cancer death in children, are more common than Hodgkin lymphoma, ovarian and testicular cancer and are responsible for more deaths than malignant melanoma.
Overall, the one-year relative survival rate is about 40% for patients diagnosed in the United States. The five-year survival rate is only about 5%. Treatment outcome remains poor, with a median survival rate of about 15 months.
Current Treatment/Management
A patient’s care team will take into account age, functional status, medical history and medication tolerability when planning the best treatment. For most newly diagnosed patients, the standard approach utilizes what is known as the Stupp protocol. Treatment is comprised of maximal surgical resection, which allows for accurate histological diagnosis, tumor genotyping, and a reduction in tumor volume, followed by 6 weeks of radiotherapy and concomitant daily temozolomide and a further 6 cycles of maintenance temozolomide. In patients with minimal functional impairment, the median overall survival (“OS”) is 15 months for radiotherapy plus temozolomide versus 12 months for radiotherapy alone.
Treatment options in the relapsed or recurrent setting are less well defined, with no established standard of care and little evidence for any interventions that prolong OS. Indeed, a significant proportion of patients may not even be eligible for second-line therapy. Options include further surgical resection, reirradiation, systemic therapies such as carmustine or bevacizumab, combined approaches, or supportive care alone.
Patients may also be treated with tumor treatment fields. This is a portable device placed on the scalp that uses mild electrical fields to try to interrupt cancer cell growth.
Standard-of-care treatments fail to specifically eliminate tumor cells and are limited by incapacitating damage to surrounding normal brain and systemic tissues leading to lymphopenia and many other detrimental side effects. All of this demonstrates that a more targeted immunotherapeutic approach is needed. Over the last decade, emerging immunotherapies (such as monoclonal antibodies, oncolytic virus therapy, adoptive cell therapy, and cellular vaccines therapy) aimed at improving specific immune response against tumor cells have brought a glimmer of hope to patients with GBM. Adoptive cell therapy, including tumor-infiltrate lymphocytes (“TILs”) transfer and genetically engineered T cells transfer, is one of the most significant breakthroughs in the field of immune-oncology. Chimeric antigen receptor (“CAR”) engineered autologous T cells have produced sustained remissions in refractory lymphomas, but this approach needs further study in the treatment of solid tumors. While there is significant potential with targeted immunotherapy in GBM, significant challenges remain, including primarily the difficulty of crossing the BBB.
Bi-Specific Antibodies
The concept of bispecific antibodies was first introduced in 1980s as a method to target multiple antigens by a single antibody. The recombinant bispecific antibodies are classified into two types. The first are antibodies containing the crystallizable region (i.e., Fc-containing antibodies) and the second are antibody derivatives without Fc regions. The Fc region is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. The mechanism of action of bispecific antibodies includes binding to the tumor cells on one side through the Fab (antigen-binding region) portion of the antibody against the tumor-specific antigen (such as CD19, HER2, EGFR, or GD2) and to the immune effector cells such as T cells and NK cells, which leads to activation of those immune effector cells and Fc-receptor bearing phagocytic cells such as monocytes/macrophages that can also mediate direct lysis of the tumor cells.
Bispecific antibodies termed bispecific T cell engagers (“BiTEs”) are monomeric proteins consisting of two antibody-derived single-chain variable fragments (“scFvs”) translated in tandem. These constructs possess one effector-binding arm specific for the epsilon subunit of T-cell CD3 and an opposing target-binding arm directed against an antigen that is expressed on the surface of tumor cells (e.g., EGFRvIII).
We believe EGFRvIII is an attractive target tumor specific antigen, in part because it is specific to cancer cells and is not expressed in non-tumor tissue. Importantly, antibodies directed against EGFRvIII are entirely tumor-specific and do not cross react with the wild-type receptor located on healthy cells. Therefore, by retargeting T cells against the tumor-specific EGFRvIII antigen, we believe we can avoid killing healthy tissue and the related adverse effects. EGFRs are involved in deregulated cancer signaling pathways, leading to atypical proliferation and growth of tumor cells. EGFRvIII is the most common variant not presented in a major histocompatibility complex (“MHC”) -dependent manner and is seen in approximately 31 to 50% of patients with GBM and in a broad array of other cancers including breast and lung carcinoma. Lung and breast carcinoma are the two main types of cancer that lead to secondary brain tumors (i.e., brain metastases) in about 25% of these patients. Among patients with EGFRvIII-positive GBM, 37 to 86% of tumor cells express the mutated receptor, indicating that the mutation is translated with significant consistency.
Among patients with GBM, expression of EGFRvIII is an independent, negative prognostic indicator. EGFRvIII also enhances the growth of neighboring EGFRvIII-negative tumor cells via cytokine-mediated paracrine signaling and by transferring a functionally active oncogenic receptor to EGFRvIII-negative cells through the release of lipid-raft related microvesicles. Recent research has also found that EGFRvIII is expressed in glioma stem cells, an important consideration given the paradigm that tumor stem cells represent a subpopulation of cells that give rise to all differentiated tumor cells. Altogether, the specificity, high frequency of surface expression and oncogenicity of the EGFRvIII mutation make it an ideal target for antibody-based immunotherapy.
The divalent structure of BiTEs brings T cells into close proximity to the tumor cell, creating a synapse. Following BiTE-mediated synapse formation, T cells proliferate, secrete pro-inflammatory cytokines and express surface activation markers. Following BiTE-mediated synapse formation, T cells release perforin and granzyme proteases that kill tumor cells. BiTEs are capable of mediating serial rounds of killing and can trigger specific tumor cell killing from naïve T cells at exceedingly low concentrations and effector-to-target ratios.
It is well established that certain gliomas, such as glioblastoma, are uniquely shielded from the immune system due to its location within the CNS. While this privilege is not absolute, a significant proportion of tumors have been noted to be devoid of any TILs that can be redirected by bispecific T-cell engagers. In those tumors that do demonstrate invasion by TILs, they are often induced to be dysfunctional and anergic by the suppressive tumor microenvironment. Increased numbers of intratumoral CD8+ cytotoxic T lymphocytes (“CTLs”) have been associated with favorable outcomes in patients with glioblastoma.
Concomitant administration of stimulated CTLs may therefore synergistically enhance the efficacy of this treatment. The migration of T-cell engagers across the BBB may also be facilitated by activated T cells which adhere to the brain microvascular endothelium and subsequently cross by diapedesis. Concurrent administration of activated functional T cells could therefore enhance the trafficking of bispecific T-cell engagers and other therapeutics into the intracranial compartment, increasing their density at the tumor site and thus the therapeutic effect.
Additionally, target cell killing with BiTE occurs in the absence of regular MHC peptide antigen recognition and costimulation and is therefore resistant to certain immune escape mechanisms affecting antigen presentation and those affecting generation of tumor-specific T cell clones. Because the CD3ε target of BiTE antibody construct is the same in CD8+ and CD4+ T cells of any phenotype, they are all engaged, leading to a polyclonal T cell activation, expansion and broad tumor cell killing.
Bispecific T-cell engagers offer immunotherapy in a manufacturing format which is both scalable and standardizable. In contrast to CAR T cells, T-cell engagers do not require initial lymphodepletion. Ex vivo manipulation of autologous cells has significant limitations, including the need for a centralized manufacturing infrastructure with extensively trained laboratory personnel to genetically modify each patient’s own T cells, use viral transduction which poses uncertain risks, are limited to the initial subset of T cells manipulated and infused, and still face uncertainty as to the optimal T cell phenotype to infuse.
Our Product Pipeline
APTN-101
We have recently reported the development of our first novel T cell engaging molecule, known as APTN-101, using our BRiTE technology. BRiTE focuses on the transport of difficult to deliver T cell targeting agents across the BBB allowing access to the immunoprivileged brain and overcoming the challenges with other immunotherapeutic approaches. This is accomplished by sequentially or simultaneously administering both BRiTE and specifically activated T cells by adoptive transfer. APTN-101 was designed to specifically redirect T cells against tumors expressing a well-characterized, mutated form of the EGFR, EGFRvIII, on a number of tumor types, including GBM. Because EGFRvIII is exclusively expressed on tumor cells, but not normal healthy cells, it represents an ideal target for immunotherapy.
APTN-101 (EGFRvIII x CD3 BRiTE) successfully activates human T cells against EGFRvIII expressing target cells, in the absence of any additional immunostimulatory signal, resulting in the secretion of Th-1-associated cytokines and tumor-cell killing. APTN-101 is similarly effective in vivo. Intravenous administration of APTN-101 induced consistent antitumor responses in mice bearing established, late-stage, aggressive, intracerebral patient-derived gliomas, rapidly achieving complete remission rates as high as 75% in the absence of apparent toxicity. Given the exquisite tumor-specificity of APTN-101, it represents a critical conceptual advance in safety contrary to target antigens having a promiscuous expression pattern.
The concept of BRiTE is the combination of novel T cell targeting agents with specifically activated polyclonal T cells. In order to exert antineoplastic affects against brain tumors, both the T cell targeting agent and T cells need to efficiently access areas that have long been considered as immunoprivileged. While circulating naïve T cells do not typically penetrate the CNS, activated T cells are known to cross the BBB to perform routine immunosurveillance of the central nervous system (Figure 1).
Figure 1- The process of T cells crossing the inflamed BBB is coordinating and sequential. Briefly, activated T cells initially arresting on the endothelium is mediated by the lymphocyte-associated antigen-1 (“LFA- 1”) and α4β1-integrin expressed on the T cells, respectively binding to the intracellular cell adhesion molecule 1 (“ICAM1”) and adhesion molecules vascular cell adhesion molecule 1 (“VCAM1”) on brain endothelial cells. Subsequently, the T cell crawling and polarization exclusively involve LFA-1 and ICAM1/2 interactions. After arriving at sites where are rich in the laminin isoform α4 but not laminin β5, the T cells use α6β1-integrin to traverse the endothelial basement membrane.
Upon intravenous administration, the T cell targeting agent (i.e., EGFRviii x CD3) binds to circulating T cells via its CD3 receptor and carries or “hitchhikes” the agent to tumors located behind the BBB. Studies in aggressive orthotopic GBM models have revealed that adoptive transfer of activated T cells significantly increases the biodistribution of intravenously administered EGFRvIII x CD3 BRiTE to orthotopic glioma (Figure 2).
Figure 2- Mass spectroscopy demonstrates that pre-administration (four days) of ex vivo activated T cells increases the biodistribution of intravenously administered EGFRvIII x CD3 to the brain parenchyma.
BRiTE circumvents ordinary clonotypic T-cell specificity, potentially allowing any T-cell, regardless of endogenous specificity or phenotype, to exert an anti-neoplastic effect. In vivo experiments show that BRiTEs can reactivate potentially unresponsive, anergic T cells, such as those frequently encountered among TIL populations thereby enhancing the spread of T cells reactive towards other antigens (epitope spreading). Proximal contact between T cells and tumor cells could directly reactivate tumor infiltrating lymphocytes specific for cancer antigens other than directed by BRiTE, without cross-presentation. The EGFRvIII x CD3 BRiTE molecule has the potential to directly activate and expand pre-existing T cells among a polyclonal population that are specific for tumor antigens other than EGFRvIII. Indeed, others have discovered that by re-activating pre-existing T cell clones using a CD3 binding bispecific antibody specific for Wilms’ tumor protein (WT1) it is possible to induce effective and persistent epitope spreading responses to multiple antigens. If the clinical utility of this mechanism of epitope spreading is confirmed, this could provide an exciting mechanism to combat tumor heterogeneity.
Importantly, our data suggest that once APTN-101 reaches the brain, it can activate even suppressive Tregs to kill glioblastoma tumor cells by redirecting their natural granzyme-mediated cytotoxic potential and enhance a cytotoxic immune response. These findings not only highlight a new mechanism by which BRiTEs may circumvent certain aspects of Treg mediated suppression, but also have broader implications with regard to the natural functional role of activated, tumor infiltrating Tregs that ordinarily suppress and kill cytotoxic T lymphocytes in the tumor microenvironment.
By tethering cytotoxic effectors to target cells without the need for antigen presentation via the MHC, BRiTEs can furthermore overcome tumor immune escape mechanisms, such as the downregulation of MHC.
In addition to enhancing the biodistribution of EGFRvIII x CD3 BRiTE to the brain, the activated polyclonal T cells (compared to the addition of no activated polyclonal T cells or naïve polyclonal T cells) have the potential to restore effector T cells function at intracerebral sites (Figure 3) leading to cures in greater than 75% of animals.
Figure 3- IV administration of activated T cells enhances hEGFRvIII-CD3 bi-scFv efficacy against syngeneic, highly-invasive, orthotopic glioma (right panel) compared to IV administration of naïve T cells when combined with hEGFRvIII-CD3 bi-scFv (left panel). The highly invasive murine glioma CT-2A-EGFRvIII was implanted orthotopically in human CD3 transgenic mice (females, 8-10 weeks old, n=10 per group).
Next, we hypothesized that the increase in efficacy observed with the pre-administration of activated polyclonal T cells would be abrogated if those T cells were to be blocked from entering the CNS parenchyma. Natalizumab, a clinically approved drug for the treatment of multiple sclerosis, functions by binding to polyclonal T cells and preventing their association with receptors involved in the process of extravasation. Remarkably, in cohorts of mice receiving adoptive transfer of activated polyclonal T cells along with treatment with the extravasation blocking molecule natalizumab, efficacy was decreased to levels observed in cohorts that did not receive adoptive transfer of activated polyclonal T cells (Figure 4).
Figure 4- Blocking T cell extravasation with Natalizumab (αVLA-4) abrogates the observed increase in efficacy with adoptive cell transfer (n=8 per group). Natalizumab is a clinically approved drug for the treatment of multiple sclerosis that functions by blocking T cell extravasation.
We have also demonstrated an effective “antidote” for any potential toxicity that may result from administration of the EGFRvIII x CD3 BRiTE in a clinical setting. By administering a short peptide that spans the EGFRvIII mutation (PEPvIII), we have effectively blocked bispecific antibody function both in vitro and in vivo, providing a tool highly likely to aid in safe clinical administration of any EGFRvIII targeted bispecific antibody.
The above data demonstrates that BRiTE technology has the ability to transport difficult to deliver agents, including T cell targeting agents, across the BBB and demonstrate superior antineoplastic activity in aggressive orthotopic models of GBM while having an acceptable safety profile. This newly uncovered hitchhiking mechanism of drug delivery to the CNS provides an important tool to enhance the immunotherapy of brain tumors and has potentially far-reaching consequences for the treatment of other CNS disorders, such as Alzheimer’s or Parkinson’s disease, where issues regarding drug delivery to the CNS are relevant.
In summary, the results of preclinical studies demonstrate that the EGFRvIII targeting BRiTE may provide a safe, highly effective therapeutic option for GBM patients. Future studies will determine whether these results can be recapitulated in the clinical setting and whether BRiTEs favorably interact with other therapies that are currently employed as a standard-of-care for GBM patients.
APTN-101 Clinical Studies
The proposed Phase 1 study will evaluate a novel hEGFRvIII-CD3-biscFv Bispecific T cell engager (BRiTE) in patients diagnosed with pathologically documented supratentorial WHO grade IV malignant glioma with an EGFR mutation (either newly diagnosed or at first progression/recurrence) at the Preston Robert Tisch Brain Tumor Center at Duke University.
The primary objective of this Phase 1 study is to determine the safety and tolerability of BRiTE and recommend Phase 2 dose of BRiTE injected with and without activated polyclonal T-cells in among a patient population that includes newly diagnosed patients after completion of standard of care therapy consisting of radiation and adjuvant temozolomide, and patients at first progression (defined as progression during or after standard of care radiation and adjuvant temozolomide).
Another secondary objective is to describe the PK in subjects treated with BRiTE. A population PK analysis will be performed to characterize the PK of BRiTE using the software Nonlinear Mixed Effects Modeling (NONMEM, version 7.2). Different structural PK models (e.g., 1 and 2 compartment) with linear or non-linear (e.g., Michaelis-Menten) kinetics will be fitted to the plasma concentration-time data of BRiTE.
Exploratory objectives include an evaluation of the pharmacodynamics effect of BRiTE, an evaluation of the formation and incidence of anti-BRiTE antibodies, and a description of overall survival and progression-free survival.

License Agreement
Patent License Agreement with Duke University
Effective January 11, 2023, Private Adaptin entered into a patent license agreement (the “Duke License”) with Duke University, a nonprofit educational and research institution organized under the laws of North Carolina (“Duke University”), whereby Duke University granted Private Adaptin an exclusive license with a right to grant sublicenses to “BISPECIFIC EGFRvIII ANTIBODY ENGAGING MOLECULES,” “HUMAN BISPECIFIC EGFRvIII ANTIBODY AND CD3 ENGAGING MOLECULES,” “CERTAIN IMPROVED HUMAN BISPECIFIC EGFRvIII ANTIBODY ENGAGING MOLECULES” and “ENHANCED DELIVERY OF DRUGS AND OTHER COMPOUNDS TO THE BRAIN AND OTHER TISSUES” (together, the “precision medicine technology”). With this technology, which the Company assumed pursuant to the Merger, we intend to develop our BRiTE Platform, a combination of an immune cell engager with activated functional T-cells, which focuses on transporting difficult to deliver agents across the blood brain barrier, allowing access to the immunoprivileged central nervous system. Under the Duke License, we are required to use commercially reasonable efforts to obtain and retain the relevant governmental approvals and to commercialize the precision medicine technology. We must also use reasonable efforts to reach certain commercialization and research and development milestones as outlined in the Duke License.
On August 8, 2024, Private Adaptin entered into a Sponsored Research Agreement (the “SRA”), which the Company assumed pursuant to the Merger, whereby Duke University agreed to perform research exploring the administration methods of our BRiTE Platform for a fixed fee. The Duke License has been amended (the “First Amendment”) such that the Company has the option to add any invention conceived as a result of the performance under the SRA to the license.
As part of the consideration for the license, Private Adaptin issued Duke University shares, representing 5% of its issued and outstanding common stock on a fully diluted basis. Following the Merger, Duke University holds 2.0% of the combined Company. We also agreed to make payments based on clinical and commercial milestones and continuing royalty payments on any sales made after approval by regulatory authorities. These milestones include initiation of a Phase II or Phase III clinical trials, submission of applications for market approval in multiple jurisdictions including the United States, European Union and Japan and the initiation of post-approval commercial sales in the same jurisdictions. Based on an assumption that all milestones related to the current development program are met during the course of the Duke License, these milestone payments would total approximately $11.7 million. Under the terms of the Duke License, we must pay running royalties equal to low- to mid-single digit percentages of annual net sales, depending on the level of sales by us, our sublicensees and affiliates in that year, and subject to downward adjustment to low single digit percentages of our net annual sales in the event there is no valid claim of a patent for the product, with minimum annual royalty levels established. We also must pay Duke University low to mid-double-digit percentages of any sublicensing fees as set forth in the Duke License. We will be responsible for all patent expenses incurred by Duke University and must reimburse Duke University for previous patent expenses incurred by Duke University for filing and prosecution of the patent rights.
The term of the Duke License will extend until the expiration of the last to expire patent rights, subject to early termination as set forth in the Duke License. The foregoing descriptions of the Duke License, First Amendment and SRA do not purport to be complete and are qualified in their entirety by the terms and conditions of the Duke License, First Amendment and SRA, forms of which are attached hereto as Exhibits 10.1, 10.2 and 10.3, respectively, and are incorporated herein by reference.
Manufacturing and Supply
We contract with third parties for the manufacturing of all of our product candidates, and for pre-clinical and clinical studies and intend to continue to do so in the future. We do not own or operate any manufacturing facilities and we have no plans to build any owned clinical or commercial-scale manufacturing capabilities. We believe that the use of contract manufacturing organizations (“CMOs”) eliminates the need to directly invest in manufacturing facilities, equipment and additional staff. Although we rely on contract manufacturers, our personnel and consultants have extensive manufacturing experience overseeing CMOs.
We have produced the EGFRvIII x CD3 BRiTE in a fashion suitable for clinical translational and compatible with clinical biologic manufacturing infrastructure. This has included generating and certifying a Master Cell Bank and developing a scalable expression and tag-free purification and formulation process suitable for clinical translation. On the basis of our data and development work, we have had a CMO produce clinical-grade EGFRvIII x CD3 BRiTE suitable for clinical study.
As we further develop our product candidates, we expect to consider secondary or back-up manufacturers for both active pharmaceutical ingredient and drug product manufacturing. To date, our third-party manufacturers have met the manufacturing requirements for our product candidates in a timely manner. We expect third-party manufacturers to be capable of providing sufficient quantities of our product candidates to meet anticipated full-scale commercial demand but we have not assessed these capabilities beyond the supply of clinical materials to date. We currently engage CMOs on a “fee for services” basis based on our current development plans. We plan to identify CMOs and enter into longer-term contracts or commitments if and as we move our product candidates into Phase 3 clinical trials.
We believe alternate sources of manufacturing will be available to satisfy our clinical and potential future commercial requirements; however, we cannot guarantee that identifying and establishing alternative relationships with such sources will be successful, cost-effective, or completed on a timely basis without significant delay in the development or commercialization of our product candidates. All of the vendors we use are required to conduct their operations under current Good Manufacturing Practices (“cGMP”), a regulatory standard for the manufacture of pharmaceuticals.
Competition
The pharmaceutical industry is highly competitive and characterized by intense and rapidly changing competition to develop new technologies and proprietary products, particularly in some of the areas of high unmet medical need that we are targeting. Our potential competitors include both major and specialty pharmaceutical and biotechnology companies worldwide, many of which have far greater resources and access to capital than we do. In particular, Affimed N.V. and NexImmune, Inc. are studying the combination of immune cell engagers with T or NK cells using a different bispecific immune cell engager, and Amgen Inc. and Genentech, Inc. (a wholly owned subsidiary of Roche Holding AG) have programs using a form of EGFRvIII x CD3 bispecific T cell engager (although neither are using them in combination with activated T cells). Our success will be based in part on our ability to identify, develop, and manage a portfolio of safe and effective product candidates that address the unmet needs of patients before our competitors.
Government Regulations
The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of drugs, such as those we are developing. Along with our third-party contractors, we will be required to navigate the various preclinical, clinical, and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidates. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources.
FDA Regulation of Drugs
Before any of our drug product candidates may be marketed in the United States, they must be approved by the FDA. The process required by the FDA before drug product candidates may be marketed in the United States generally involves the following:
● completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s current Good Laboratory Practices regulations;
● submission to the FDA of an IND, which must become effective before human clinical trials may begin and must be updated annually or when significant changes are made;
● approval by an independent institutional review board (“IRB”) or ethics committee for each clinical site before a clinical trial can begin;
● performance of adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed product candidate for its intended purpose;
● preparation of and submission to the FDA of a New Drug Application (“NDA”) after completion of all required clinical trials;
● a determination by the FDA within 60 days of its receipt of an NDA to file the application for review;
● satisfactory completion of an FDA Advisory Committee review, if required by the FDA;
● satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP, and to assure that the facilities, methods, and controls are adequate to preserve the product’s continued safety, purity and potency, and of selected clinical investigational sites to assess compliance with current Good Clinical Practices; and
● FDA review and approval of the NDA to permit commercial marketing of the product for particular indications for use in the United States, which must be updated annually and when significant changes are made.
The testing and approval processes require substantial time, effort, and financial resources and each may take several years to complete. The FDA may not grant approval on a timely basis, or at all, and we may encounter difficulties or unanticipated costs in our efforts to secure necessary governmental approvals, which could delay or preclude us from marketing our product candidates. The FDA may delay or refuse approval of an NDA if applicable regulatory criteria are not satisfied, or may require additional testing, information, and/or post-marketing testing and surveillance to monitor safety or efficacy of a product candidate.
If regulatory approval of a product candidate is granted, such approval may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the NDA with a Risk Evaluation and Mitigation Strategy (“REMS”) plan to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries, and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing regulatory standards is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing studies. In addition, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.
FDA Programs for Expedited Review and Increased Exclusivity
A sponsor may seek approval of a product candidate under Fast Track and Breakthrough Therapy programs designed to accelerate the FDA’s review and approval of new drug candidates that meet certain criteria, and/or to receive increased exclusivity under the orphan drug program. We intend to pursue these programs where our product candidates qualify.
Fast Track. A new drug candidate is eligible for Fast Track designation if it is intended to treat a serious or life-threatening condition, fill an unmet medical need, and demonstrate a significant improvement in the safety or effectiveness in the treatment of that condition.
A drug that receives Fast Track designation is eligible for the following:
● more frequent meetings with FDA to discuss the drug’s development plan and ensure collection of appropriate data needed to support drug approval;
● more frequent written correspondence from FDA about the design of clinical trials;
● priority review to shorten the FDA review process for a new drug from ten months to six months; and
● rolling review, which means we can submit completed sections of its NDA for review by FDA, rather than waiting until every section of the application is completed before the entire application can be reviewed.
Under the accelerated approval program, the FDA may approve an NDA on the basis of either a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Fast Track designation and priority review do not change the standards for approval but may expedite the development or approval process.
Breakthrough Therapy. A new drug candidate is eligible for Breakthrough Therapy designation if it is intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on one or more clinically significant endpoints.
A drug that receives Breakthrough Therapy designation is eligible for the following:
● All Fast Track designation features;
● Intensive guidance from the FDA on an efficient drug development program, beginning as early as Phase 1; and
● FDA organizational commitment involving senior managers.
Orphan Drug Designation. Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug candidate intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that costs of research and development of the drug for the indication can be recovered by sales of the drug in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Although there may be some increased communication opportunities, orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.
If a drug candidate that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications, including a full NDA, to market the same drug for the same indication for seven years, except in very limited circumstances, such as if the second applicant demonstrates the clinical superiority of its product or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.
As in the United States, designation as an orphan drug for the treatment of a specific indication in the European Union must be made before the application for marketing authorization is made. Orphan drugs in Europe enjoy economic and marketing benefits, including up to ten years of market exclusivity for the approved indication unless another applicant can show that its product is safer, more effective or otherwise clinically superior to the orphan designated product.
The inability to obtain or failure to maintain adequate product exclusivity for our product candidates could have a material adverse effect on our business prospects, results of operations and financial condition.
Other Healthcare Laws and Compliance Requirements
Our sales, promotion, medical education, clinical research, and other activities following product approval will be subject to regulation by numerous regulatory and law enforcement authorities in the United States in addition to the FDA, including potentially the Federal Trade Commission, the Department of Justice, the Centers for Medicare and Medicaid Services (“CMS”), the U.S. Department of Health and Human Services (“DHHS”) Office of Inspector General, and other divisions of DHHS, and state and local governments.
Our business and our relationships with customers, physicians, and third-party payors are and will continue to be subject, directly and indirectly, to federal and state healthcare fraud and abuse laws and regulations. These laws also apply to the physicians and third-party payors who will play a primary role in the recommendation and prescription of our product candidates, if they become commercially available products. These laws may constrain the business or financial arrangements and relationships through which we might market, sell and distribute our products and will impact, among other things, any proposed sales, marketing and educational programs. There are also laws, regulations and requirements applicable to the award and performance of federal grants and contracts. If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to them, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, disgorgement, the reimbursement of overpayments, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs, imprisonment, contractual damages, reputational harm, and diminished profits and earnings-any of which could adversely affect our ability to operate our business and our financial results.
Restrictions under applicable federal and state healthcare related laws and regulations include but are not limited to the following:
● the federal Anti-Kickback Statute;
● the civil federal False Claims Act;
● the criminal federal False Claims Act;
● the Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and its implementing regulations (collectively, “HIPAA”);
● the civil monetary penalties statute;
● federal transparency laws, including the federal Physician Sunshine Act (“PSA”); and
● analogous or similar state, federal, and foreign laws, regulations, and requirements.
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations involve substantial costs. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other laws, regulations, or other requirements that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, restitution exclusion from government funded healthcare programs, corporate integrity agreements, deferred prosecution agreements, debarment from government contracts and grants and refusal of future orders under existing contracts, contractual damages, the curtailment or restructuring of our operations and other consequences. If any of the physicians or other healthcare providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, that person or entity may be subject to criminal, civil, or administrative sanctions, including exclusions from government funded healthcare programs. Moreover, availability of any federal grant funds which we may receive or for which we may apply is subject to federal appropriations law. Such grant funding may also be withdrawn or denied due to a violation of the above laws and/or for other reasons.
Coverage and Reimbursement; Healthcare Reform
Sales of pharmaceutical products depend significantly on the extent to which coverage and adequate reimbursement are provided by third-party payers. Third-party payers include state and federal government health care programs, managed care providers, private health insurers, and other organizations. Although we currently believe that third-party payers will provide coverage and reimbursement for our product candidates, if approved, we cannot be certain of this. Third-party payers are increasingly challenging the price, examining the cost-effectiveness and reducing reimbursement for medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. The United States government, state legislatures, and foreign governments have continued implementing healthcare reform and cost containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Adoption of price controls and cost containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. We might need to conduct expensive clinical studies to demonstrate the comparative cost-effectiveness of our product candidates. Third-party payers might not consider the product candidates that we develop to be cost-effective and not cover or sufficiently reimburse for their use. It is time-consuming and expensive for us to seek coverage and reimbursement from third-party payers, as each payer will make its own determination as to whether to cover a product and at what level of reimbursement. Thus, one payer’s decision to provide coverage and adequate reimbursement for a product does not assure that another payer will provide coverage or that the reimbursement levels will be adequate. Moreover, a payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved.
Foreign Regulation
In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our product candidates to the extent we choose to develop or sell any product candidates outside of the United States. The approval process varies from country to country and the time may be longer or shorter than that required to obtain FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement, and privacy, can vary greatly from country to country.
Employees
As of the Effective Time of the Merger, we had four employees, all of whom are located in the United States. None of our employees is represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.
Property
The Company owns no real property. We maintain a month-to-month membership providing mail services and shared space for meetings and other business activities at 3540 Toringdon Way, Suite 200, #250, Charlotte, North Carolina. The current rent is approximately $100 per month.
Litigation
From time to time, we may become involved in various lawsuits and legal proceedings that arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm business.
We are currently not aware of any pending legal proceedings to which we are a party or of which any of our property is the subject, nor are we aware of any such proceedings that are contemplated by any governmental authority.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
As discussed elsewhere in this Annual Report on Form 10-K for the year ended December 31, 2024 and below, on February 11, 2025, our wholly owned subsidiary, Adaptin Acquisition Co., merged with and into Private Adaptin. In connection with the Merger, Private Adaptin became a wholly owned subsidiary of the Company, and the Company changed its name to Adaptin Bio, Inc.
The following discussion and analysis is exclusively attributable to the operations of Unite Acquisition for the years ended December 31, 2024 and 2023. This discussion and analysis should be read in conjunction with our financial statements for the years ended December 31, 2024 and 2023 and the related notes thereto, which have been prepared in accordance with GAAP. The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
Overview of our Business
We were incorporated in the State of Delaware on March 10, 2022. From inception through the date of the Merger, the Company was engaged in organizational efforts and obtaining initial financing. The Company was formed as a vehicle to pursue a business combination and focused its efforts to identify a possible business combination.
As of December 31, 2024, the Company was considered to be a “blank check” company. The Securities and Exchange Commission, or SEC, defines those companies as a development stage company that has no specific business plan or purpose or has indicated that its business plan is to engage in a merger or acquisition with an unidentified company or companies, or other entity or person, and that is issuing a penny stock, as defined in in Rule 3a51-1 under the Exchange Act. Many states have enacted statutes, rules and regulations limiting the sale of securities of “blank check” companies in their respective jurisdictions. As of December 31, 2024, the Company was also a “shell company,” defined in Rule 12b-2 under the Exchange Act as a company with no or nominal assets (other than cash) and no or nominal operations. As a result of the Merger, we have ceased to be a shell company.
In addition, the Company is an “emerging growth company,” as defined in the JOBS Act, and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of section 404(b) of the Sarbanes-Oxley Act, and exemptions from the requirements of Sections 14A(a) and (b) of the Exchange Act to hold a nonbinding advisory vote of stockholders on executive compensation and any golden parachute payments not previously approved.
The Company has also elected to use the extended transition period for complying with new or revised accounting standards under Section 102(b)(1) of the JOBS Act. This election allows us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.
We will remain an “emerging growth company” until the earliest of (1) the last day of the fiscal year during which our gross revenues exceed $1.235 billion, (2) the date on which we issue more than $1 billion in non-convertible debt in a three year period, (3) the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to an effective registration statement filed pursuant to the Securities Act, or (4) when the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter. To the extent that we continue to qualify as a “smaller reporting company,” as such term is defined in Rule 12b-2 under the Exchange Act, after we cease to qualify as an emerging growth company, certain of the exemptions available to us as an emerging growth company may continue to be available to us as a smaller reporting company, including: (1) not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes Oxley Act; (2) scaled executive compensation disclosures; and (3) the requirement to provide only two years of audited financial statements, instead of three years.
From inception through the date of the Merger, the Company did not conduct any active operations, except for its efforts to locate suitable acquisition candidates. No revenue has been generated by the Company since inception. Following the Merger, we expect to continue to incur significant losses for the foreseeable future. We anticipate that a substantial portion of our capital resources and efforts in the foreseeable future will be focused on completing the necessary development activities required for applying for and obtaining regulatory approval for our product candidates and, subsequently, preparing for potential commercialization of our product candidates.
We expect to continue to incur significant expenses and operating losses for at least the next several years. Our net losses may fluctuate significantly from period to period, depending on the timing of our planned clinical trials and expenditures on other research and development activities. We expect our expenses will increase substantially over time as we:
● continue our ongoing and planned development of APTN-101, including pre-clinical activity and our Phase 1 investigator-led trial for the treatment of GBM;
● build a portfolio of product candidates through development, or the acquisition or in-license of drugs, product candidates or technologies;
● initiate preclinical studies and clinical trials for APTN-101 for any additional indications we may pursue and for any additional product candidates that we may pursue in the future;
● hire clinical, regulatory and scientific personnel;
● add operational, financial and management information systems and personnel, including personnel to support our product development efforts; and
● incur additional legal, accounting, insurance and other expenses associated with operating as a public company.
Based on our current operating plan, we anticipate that our existing cash balance will not be sufficient to fund our operating activities for the next twelve months and, as such, we will need to obtain additional funding. We plan to continue to fund our losses from operations through cash on hand, as well as through future equity offerings, debt financings, or other third-party funding. There can be no assurance that additional funds will be available when needed from any source or, if available, will be available on terms that are acceptable to us. Even if we raise additional capital, we may also be required to modify, delay or abandon some of our plans which could have a material adverse effect on our business, operating results and financial condition and our ability to achieve our intended business objectives. Any of these actions could materially harm our business, results of operations and future prospects.
As of December 31, 2024, the Company had $12,619 in cash. As of December 31, 2023, the Company had $380 in cash. On March 10, 2022, the Company issued a promissory note to Lucius Partners LLC (“Lucius Partners”), which was then the sole stockholder of the Company, pursuant to which the Company agreed to repay the sum of any and all amounts that Lucius Partners may advance to the Company on or before the date that the Company consummates a business combination with a private company or reverse takeover transaction or other transaction after which the Company would cease to be a shell company (as defined in Rule 12b-2 under the Exchange Act). The Company used the proceeds from the note to cover its expenses. Although Lucius Partners has no obligation to advance funds to the Company under the terms of the note, it is anticipated that it may advance funds to the Company as fees and expenses are incurred in the future. As a result, the Company issued the note in anticipation of such advances. Interest shall not accrue on the outstanding principal amount of the note except if an Event of Default (as defined in the note) has occurred. In the event of an Event of Default, the entire note shall automatically become due and payable (the “Default Date”) and starting from five days after the Default Date, the interest rate on the note shall accrue at the rate of 18% per annum. As of December 31, 2024 and 2023, the amounts due under the note payable was $0 and $81,219, respectively.
On October 28, 2024, the Company issued an Unsecured Promissory Note to Lucius Partners Opportunity Fund, LP and received $275,000. See “Issuance of Unsecured Promissory Note” below.
At December 31, 2024, the Company had an agreement to pay Nathan Pereira a monthly fee of $1,000 for his services as a director. Mr. Pereira served as a director of the Company during 2023 and 2024 and up to the date of the Merger. The Company incurred director fees with Mr. Pereira amounting to $12,000 for the years ended December 31, 2024 and 2023. In connection with the Merger, Mr. Pereira resigned as a director and the services agreement was terminated. As a condition to the Merger, the Company entered into a pre-Merger indemnity agreement with Mr. Pereira, pursuant to which the Company agreed to indemnify Mr. Pereira for actions taken by him in his official capacity relating to the consideration, approval and consummation of the Merger and certain related transactions.
Effective March 10, 2022, the Company also entered into a services agreement with Lucius Partners, pursuant to which we paid a quarterly fee of $1,250 to Lucius Partners for advisory, accounting, and administrative support services. This services agreement was terminated in connection with the Merger.
Our ability to continue as a going concern is dependent upon our ability to generate future profitable operations and/or to obtain the necessary financing to meet our obligations and repay our liabilities arising from normal business operations when they come due.
Liquidity and Capital Resources
As of December 31, 2024 and 2023, the Company had total assets equal to $12,619 and $380, respectively, comprised exclusively of cash. The Company’s current liabilities as of December 31, 2024 and 2023, totaled $286,676 and $113,277, respectively, was comprised of related party payables, accounts payable and accrued liabilities and amounts due under a note payable to a stockholder and an unsecured promissory note issued to a related party. The Company can provide no assurance that it can continue to satisfy its cash requirements for at least the next twelve months.
The following is a summary of the Company’s cash flows provided by (used in) operating and financing activities:
As of December 31,
Net cash used in operating activities $ (181,542 ) $ (81,035 )
Net cash provided by financing activities 193,781 80,915
Net (decrease) / increase in cash and cash equivalents $ 12,239 $ (120 )
Issuance of Promissory Note to a Stockholder and Director
On March 10, 2022, the Company issued a promissory note to Lucius Partners, then the sole stockholder of the Company, pursuant to which the Company agreed to repay the sum of any and all amounts that Lucius Partners may advance to the Company on or before the date that the Company consummates a business combination with a private company or reverse takeover transaction or other transaction after which the Company would cease to be a shell company (as defined in Rule 12b-2 under the Exchange Act). The Company used the proceeds from the note to cover its expenses. Although Lucius Partners has no obligation to advance funds to the Company under the terms of the note, it is anticipated that it may advance funds to the Company as fees and expenses are incurred in the future. As a result, the Company issued the note in anticipation of such advances. Interest shall not accrue on the outstanding principal amount of the note except if an Event of Default (as defined in the note) has occurred. In the event of an Event of Default, the entire note shall automatically become due and payable (the “Default Date”) and starting from five (5) days after the Default Date, the interest rate on the note shall accrue at the rate of 18% per annum. As of December 31, 2024 and 2023, the amounts due under the note payable was $0 and $81,219, respectively.
As of December 31, 2024, the Company had only cash assets and has generated no revenues since inception. The Company is also dependent upon the receipt of capital investment or other financing to fund its ongoing operations and to execute its business plan. If continued funding and capital resources are unavailable at reasonable terms, the Company may not be able to implement its plan of operations.
Issuance of Unsecured Promissory Note
On October 28, 2024, the Company issued an Unsecured Promissory Note (the “Promissory Note”) to Lucius Partners Opportunity Fund, LP (“LPOF”) and received $275,000. The annual interest rate on the Promissory Note is 12%. The Note matures on October 28, 2025 and can be prepaid at anytime without penalty. The Company used the proceeds to pay off the note payable - stockholder, related party payable, other accrued expenses and general expenses, held by Lucius Partners, the Company’s sole stockholder and the director fees owed to Nathan Pereira and other accrued expenses. The general partner of the new lender LPOF is Lucius Capital Partners LLC (“LCP”). The investment manager of LPOF is Lucius Capital Fund Management, LLC (“LCFM”). Lucius Partners, LCP and LCFM have two individuals in common as members, thus LPOF is considered a related party.
Results of Operations
From inception through the date of the Merger, the Company did not conduct any active operations, except for its efforts to locate suitable acquisition candidates. No revenue was generated by the Company for the years ended December 31, 2024 and December 31, 2023. It is unlikely the Company will have any revenues unless it is able to effectively execute its business plan. It is management’s assertion that these circumstances may hinder the Company’s ability to continue as a going concern. The Company’s plan of operation for the next twelve months shall be to continue its efforts to develop its product candidates.
For the years ended December 31, 2024 and 2023, the Company had a net loss of $161,160 and $85,593 respectively, comprised of accounting, audit and other professional service fees incurred in relation to the preparation and filing of the Company’s SEC filings and general and administrative expenses. For the year ended December 31, 2024, the Company also incurred interest expense in connection with the Promissory Note to LPOF described above.
Off-Balance Sheet Arrangements
We have not entered into any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources and would be considered material to investors.
Critical Accounting Estimates
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. We base our estimates on our limited historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
We have not identified any critical accounting estimates.
Contractual Obligations
As of December 31, 2024, we did not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than the note payable agreements disclosed above, an agreement to pay Nathan Pereira, a monthly fee of $1,000 for his services as a director and an agreement with Lucius Partners to pay $1,250 per quarter for advisory, accounting and administrative support services. As of December 31, 2024 and December 31, 2023, the amounts due under the note payable was $0 and $81,219, respectively. In connection with the Merger, Mr. Pereira resigned as a director and the services agreement was terminated. Also, in connection with the Merger, Lucius Partners has agreed to provide advisory services to the Company for two years following the initial closing of the Company’s private placement offering on February 11, 2025 (the “Advisory Period”) and the Company has agreed to pay to Lucius Partners a cash fee of $180,000 in advance for the first year of advisory services and a cash fee of $45,000 quarterly in advance for the second year of advisory services. The Advisory Period can be renewed for additional one-year periods upon written request by the Company within 60 days prior to the expiry of any Advisory Period.

ITEM 9A. CONTROLS AND PROCEDURES
ITEM 9A. CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this Report, is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the President and Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial and accounting officer), as appropriate to allow timely decisions regarding required disclosure.
In connection with the preparation of this Report, management, with the participation of our principal executive officer and principal financial and accounting officer, has evaluated the effectiveness of the design and operation of our predecessor, Unite Acquisition’s, disclosure controls and procedures as of December 31, 2024, pursuant to Rule 13a-15(b) under the Exchange Act. Based upon that evaluation, our principal executive officer and principal financial and accounting officer concluded that, as of December 31, 2024, our disclosure controls and procedures were still not designed and implemented and hence thereby not effective to ensure appropriate review of the internally prepared financial statements as well as the lack of adequate segregation of accounting functions which could have resulted in material misstatements in the financial statements
Unite Acquisition’s management had planned to remediate the material weaknesses described above through hiring additional qualified accounting and financial reporting personnel, and designing and implementing financial reporting systems, processes, policies and internal control, however such efforts were not complete as of December 31, 2024.
We performed additional analysis as deemed necessary to ensure that our financial statements were prepared in accordance with U.S. generally accepted accounting principles. Accordingly, management believes that the financial statements included in this Report present fairly in all material respects our financial position, results of operations and cash flows for the period presented.
Management’s Report on Internal Controls Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with generally accepted accounting principles. Because of inherent limitations, a system of internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate due to change in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. Management based this assessment on criteria for effective internal control over financial reporting described in “Internal Control - Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of its internal control over financial reporting. Management reviewed the results of its assessment with our Board of Directors.
Based on this assessment, management concluded that our predecessor, Unite Acquisition’s, internal control over financial reporting was not effective as the previously disclosed material weakness in our internal control over financial reporting continued to exist as of December 31, 2024. The material weakness identified related to the lack of segregation of duties and overall control environment, as we had insufficient internal resources to design, implement, document, and operate effective internal controls around our financial reporting process.
This Report on Form 10-K does not include an attestation report of our independent registered public accounting firm, regarding internal controls over financial reporting. Our internal control over financial reporting was not subject to such attestation as we are a “smaller reporting company” as defined by Item 10 of Regulation S-K.
Changes in Internal Control over Financial Reporting
Except for the material weaknesses in internal control over financial reporting described above, there have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15(f) under the Exchange Act that occurred during the period covered by this Report that has materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Limitations of the Effectiveness of Control
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations of any control system, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

Executive Officers
Michael J. Roberts, PhD - Chief Executive Officer and Director
Dr. Roberts has been our Chief Executive Officer and a member of our board of directors since February 2025, and was Chief Executive Officer and a director of Private Adaptin from March 2021 until February 2025. He has over 25 years of pharmaceutical research, development, corporate development, and executive experience. He is co-founder and President and CEO of Adaptin Bio and also serves on the board of directors. Prior to Adaptin he was co-founder of Corino Therapeutics and is currently its acting CEO. Dr. Roberts led and ran all activities related to Corino and the development of a disease-modifying drug called CRX-1008, which is used to treat the protein disorder transthyretin amyloidosis. He is a pharmaceutical and biotech consultant and owner of MAC B Consulting. Prior to Corino, Dr. Roberts was VP, Business Development and Corporate Officer of publicly traded Chelsea Therapeutics International, Ltd. He was responsible for business development efforts focused primarily on licensing and M&A with consideration to pipeline management. He led the sale of Chelsea Therapeutics to H. Lundbeck A/S in 2014 for approximately $658 million. Prior to Chelsea Therapeutics, Dr. Roberts was Director of Business Development for their Nektar Therapeutics’ Molecule Engineering technology and completed a number of transactions with large and specialty pharmaceutical companies. Dr. Roberts has completed pharmaceutical transactions valued at over $1B. Prior to this he was Manager of Biopharmaceutical Research at Shearwater Corporation where he led and was successful in the development of preclinical drug candidates from initial stages of research through Phase I clinical study, including inventing the product Movantik™, a treatment for opioid-induced constipation, subsequently licensed to AstraZeneca in a transaction valued at approximately $1 billion. Shearwater was sold to Inhale Therapeutic Systems (now known as Nektar Therapeutics) in 2001 for approximately $200 million. Dr. Roberts obtained his Ph.D. in Materials Science from the University of Alabama and B.S. in Chemical Engineering from Pennsylvania State University. We believe that Dr. Roberts’ experience in the life sciences industry and in the operation of publicly traded companies as an executive qualifies him to serve on our board of directors.
Simon C. Pedder, PhD - Executive Chairman and Director
Dr. Pedder has been our Executive Chairman and a member of our board of directors since February 2025, and was Executive Chairman and a director of Private Adaptin since October 2023. He has a career of over 30 years in drug development and commercialization. He was Chief Executive Officer of Nirogy from November 2021 to November 2022. From December 2016 to November 2021, he had leadership roles as Chief Business and Strategy Officer for Athenex; President and CEO of Cellectar Biosciences from April 2014 to June 2015; President and CEO of Chelsea Therapeutics International, Ltd. from May 2004 to July 2012; and Global Vice President of Oncology Pharma Business and Executive Officer at Hoffmann-LaRoche. Previous positions at Roche included Life Cycle Leader and Global Project Leader of Pegasys/IFN and Head of Hepatitis Franchise. Prior to that, he was Clinical Leader for a number of development compounds at Roche. Dr. Pedder served on the board of directors of Cerecor, Inc. from April 2018 to June 2020, Mateon Therapeutics, Inc. from March 2016 to April 2019 and Delcath Systems, Inc. from November 2017 to April 2019.

During his longstanding career in pharmaceutical development, Dr. Pedder played key roles in the successful development and commercialization of multiple proprietary pharmaceutical products including Tasmar®, Pegasys®, Copegus®, Northera® and Klisyri®. In addition to his Ph.D., Dr. Pedder obtained a Master of Science in Toxicology from Concordia University, a Joint Honors Bachelor degree in Environmental Studies/Biology from the University of Waterloo, and he completed the Roche-sponsored Pharmaceutical Executive Management Program at Columbia Business School. We believe Dr. Pedder’s experience in the life sciences industry and in the operation of publicly traded companies as an executive and board member qualifies him to serve on our board of directors.
Timothy L. Maness, CPA - Chief Financial Officer
Mr. Maness has been our Chief Financial Officer since February 2025, and was Chief Financial Officer of Private Adaptin from September 2024 to February 2025.

Additionally, Dr. Hewitt received a Master of Science degree in Toxicology and a B.Sc. (Hon) in Comparative Anatomy and Physiology from Concordia University.

Mr. Gallagher earned his Master in Business Administration from Penn State University and his Bachelor of Science in Finance from the University of Vermont. We believe that Mr. Gallagher’s extensive experience in the life sciences industry qualifies him to serve on our board of directors.
Anthony Zook

We believe Mr. Zook’s extensive commercialization experience and expertise in executive leadership qualify him to serve on our board of directors.
J. Nick Riehle
Mr. Riehle has been a member of our board of directors since February 2025. He has over 25 years of business and management experience with both large companies and start-up ventures, and 18 years of that has been as a chief financial officer of pharmaceutical and software companies, including taking these same companies public. Mr. Riehle formerly served as the CFO of Athenex, Inc., managing all aspects of the accounting, treasury, IT, HR, and legal functions and providing support to the company when it went public in June 2017.

We believe that Mr. Riehle’s experience in the life sciences industry qualifies and in the operation of publicly traded companies as a senior financial executive qualifies him to serve on our board of directors.
Corporate Governance
Appointment of Officers
Our executive officers are appointed by, and serve at the discretion of, our board of directors provided, however, that the board of directors may empower the Chief Executive Officer of the Company to appoint any officer other than the Executive Chairperson, the Chief Executive Officer, the President, the Chief Financial Officer or the Treasurer.
Board of Directors Composition
Our board of directors currently consists of five members. Dr. Roberts, Dr. Pedder, Mr. Gallagher, Mr. Zook, and Mr. Riehle have been designated to serve as members of our board of directors.
Each of our current directors will continue to serve until the election and qualification of his successor, or his earlier death, resignation, disqualification or removal.
Director Independence
Our securities are not listed on a national securities exchange or on any inter-dealer quotation system that has a requirement that a majority of directors be independent. We evaluate independence by the standards for director independence set forth in the Nasdaq Marketplace Rules. Under such rules, our board of directors has determined that all members of the board of directors except for Dr. Roberts and Dr. Pedder are independent directors under Nasdaq Listing Rule 5605(a)(2). In making such independence determination, our board of directors considered the relationships that each non-employee director has with us and all other facts and circumstances that our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.
Under Nasdaq Marketplace Rules, a director only qualifies as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.
Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (i) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (ii) be an affiliated person of the listed company or any of its subsidiaries. We intend to satisfy the audit committee independence requirements of Rule 10A-3 as of the time we list on a national securities exchange.
Our board of directors has undertaken a review of the independence of each director and considered whether each director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our board of directors determined that Messrs. Gallagher, Riehle and Zook are “independent directors” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of Nasdaq. In making these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and current and prior relationships as they may relate to us and our management, including the beneficial ownership of our capital stock by each non-employee director and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”
Family Relationships
There are no family relationships by between or among the members of the board of directors or other executive officers of the Company.
Legal Proceedings
None of the Company’s directors or executive officers are involved in any legal proceedings described in Item 401(f) of SEC Regulation S-K.
Code of Ethics
The Company has adopted a Code of Ethics and Business Conduct that applies to all officers, directors and employees (the “Code of Ethics”). The Code of Ethics is available under the heading “Governance Documents” on the Company’s website at ir.adaptinbio.com. If the Company makes any substantive amendments to the Code of Ethics or grants any waiver from a provision of the Code of Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.
The Code of Ethics addresses, among other matters, conflicts of interest and corporate opportunities, fair dealing, record- keeping and public disclosures, compliance with laws and corporate policies, confidentiality and corporate assets, and reporting and consequences of violations. The provisions of the Code of Ethics are intended to reflect current best practices and enhance the Company’s personnel’s understanding of the Company’s standards of ethical business practices, promote awareness of ethical issues that may be encountered in carrying out an employee’s or director’s responsibilities and improve clarity as to how to address ethical issues that may arise.
Insider Trading
The Company has adopted an insider trading policy governing the purchase, sale, and other dispositions of our securities by our directors, officers, and employees. We believe this policy is reasonably designed to promote compliance with insider trading laws, rules, and regulations and listing standards applicable to the Company. Additionally, our insider trading policy strongly discourages or prohibits employees, consultants, officers and directors from engaging in short sales, transactions in put or call options, hedging transactions, margin accounts or other inherently speculative transactions with respect to the Company’s stock at any time. A copy of our insider trading policy is filed as Exhibit 19 to this Report.
Committee of the Board of Directors
Our board of directors has an Audit Committee, which has the composition and responsibilities described below. Members serve on the Audit Committee until their resignation or until otherwise determined by our board of directors.
Audit Committee
The members of our Audit Committee are Messrs. Gallagher, Riehle, and Zook. Mr. Riehle serves as the Chair of this committee. The board of directors has determined that Mr. Riehle is “independent” under the Nasdaq Marketplace Rules and standards established by the SEC rules regarding audit committee members as set forth above. The board of directors has determined that Mr. Riehle qualifies as an “audit committee financial expert” as defined by applicable SEC rules.
The Audit Committee oversees on behalf of the board of directors (a) the conduct of the Company’s accounting and financial reporting processes, the audits of our financial statements and the integrity of the Company’s audited financial statements and other financial reports; (b) the performance of the Company’s internal accounting, internal auditing, and financial controls function; (c) the engagement, replacement, compensation, qualifications, independence and performance of our independent auditors, and (d) the portions of our Code of Conduct and Ethics and related policies regarding our accounting, internal accounting controls or auditing matters. The Audit Committee also reviews and approves or disapproves related party transactions identified in Item 404 of SEC Regulation S-K and makes recommendations to the full board of directors regarding the same.
The Audit Committee meets privately with our independent registered public accounting firm from time to time, and such firm has unrestricted access to, and reports directly to, the Audit Committee.
Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Exchange Act requires the Company’s directors and executive officers, and persons who own more than ten percent of a registered class of the Company’s equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities of the Company. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.
To the Company’s knowledge, based solely on the review of the copies of such reports filed with the SEC and/or furnished to the Company and written representations from the Company’s directors and executive officers that no other reports were required, during the year ended December 31, 2024, all officers, directors and greater than ten percent beneficial owners were in compliance with applicable Section 16(a) filing requirements

ITEM 11. EXECUTIVE COMPENSATION
ITEM 11. EXECUTIVE COMPENSATION.
Information with respect to the Company’s directors and executive officers is described in the section titled “Management” above.
Director Compensation
The Company incurred director fees with Nathan Pereira amounting to $12,000 for the year ended December 31, 2024. Following the Merger, the Company provides annual cash compensation of $30,000 to its non-employee directors who are not otherwise paid by a major investor in or advisor to the Company (“Independent Directors”). The chair of the Audit Committee receives an additional $15,000 in annual cash compensation. Independent Directors will also be eligible to receive such equity grants or awards as may be approved by the board of directors in its discretion. The board of directors intends to grant each Independent Director equity awards equal to 0.20% of the Company’s fully diluted shares outstanding at the time of grant. Drs. Roberts and Pedder are employees and executive officers of the Company and are not separately compensated for their service as directors.
Executive Officer Compensation
This section discusses the material components of the executive compensation program for the Company’s named executive officers who appear in the “Summary Compensation Table” below. In 2024, the “named executive officers” and their positions with the Company were as follows:
● Michael J. Robert: President and Chief Executive Officer
● Simon C. Pedder: Executive Chairman
● Timothy L. Maness: Chief Financial Officer
As required by SEC rules, our named executive officers also include Nathan Pereira, who was the former sole officer and director of Unite Acquisition until the closing of the Merger, serving as Chief Executive Officer and Chief Financial Officer. Mr. Pereira did not receive any employee compensation during the fiscal year ended December 31, 2024 and, as a result, this section is focused on the compensation of our current named executive officers.
This discussion may contain forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from the currently planned programs summarized in this discussion.
Summary Compensation Table
The following table sets forth information concerning the compensation of the named executive officers for the Company’s two most recent fiscal years.

Outstanding Equity Awards at Fiscal Year-End
As of the end of our most recently completed fiscal year, none of our named executive officers held any outstanding equity awards.
Policies and Practices Related to Stock Option Grants
The following discussion of the timing of option awards in relation to the disclosure of material nonpublic information is provided as required by Item 402(x) of Regulation S-K. The Company does not have a written policy regarding the timing of option awards in relation to the disclosure of material nonpublic information. The Company has not yet issued stock options. In the event stock options are issued, the Compensation Committee does not intend to take material nonpublic information into account when determining the timing and terms of option awards. The Company has not timed the disclosure of material nonpublic information to affect the value of executive compensation.
Pre-Merger Agreements with Named Executive Officers
Prior to the Merger, we were party to compensation agreements with Dr. Pedder and an entity owned by Dr. Roberts, as well as a consulting agreement with an entity owned by Mr. Maness. Descriptions of these agreements appear below. Upon closing of the Merger, these agreements were terminated and replaced by employment agreements with each of Dr. Roberts, Dr. Pedder, and Mr. Maness. See “Post-Merger Employment Agreements with Named Executive Officers” below.
Compensation Agreement - MAC B Consulting LLC. On October 1, 2023, the Company and MAC B Consulting LLC, d/b/a Michael J. Roberts entered into a compensation agreement (the “Roberts Compensation Agreement”). Pursuant to the Roberts Compensation Agreement, Dr. Roberts provides business and pharmaceutical development related services to the Company. The Roberts Compensation Agreement may be terminated by the Company or Dr. Roberts upon 30 days prior written notice to the other party. Pursuant to the Roberts Compensation Agreement, Dr. Roberts is entitled to receive cash compensation at a rate of $15,000 per month so long as the Company has sufficient funding.
Compensation Agreement - Simon C. Pedder. On October 1, 2023, the Company and Dr. Pedder entered into a compensation agreement (the “Pedder Compensation Agreement”). Pursuant to the Pedder Compensation Agreement, Dr. Pedder provides business and pharmaceutical development related services to the Company. The Pedder Compensation Agreement may be terminated by the Company or Dr. Pedder upon 30 days prior written notice to the other party. Pursuant to the Pedder Compensation Agreement, Dr. Pedder is entitled to receive cash compensation at a rate of $10,000 per month so long as the Company has sufficient funding.
Consulting Agreement - Adamanteus LLC. On May 31, 2023, the Company and Adamanteus LLC, d/b/a Timothy Maness entered into a consulting agreement (the “Maness Consulting Agreement”). Pursuant to the Maness Consulting Agreement, Mr. Maness provides finance and accounting services to the Company. The Maness Consulting Agreement was for an initial term of six months and has continued for subsequent six-month terms in accordance with the terms of the Maness Consulting Agreement. The Maness Consulting Agreement may be terminated by the Company or Mr. Maness upon 30 days prior written notice to the other party. Pursuant to the Maness Consulting Agreement, Mr. Maness is entitled to receive cash compensation at a rate of $300 per hour.
Post-Merger Employment Agreements with Named Executive Officers
We entered into executive employment agreements with each of Dr. Roberts, Dr. Pedder, and Mr. Maness (each an “Executive” and collectively, the “Executives”), which were effective upon the closing of the Merger. The agreements include customary non-competition, non-solicitation, and confidentiality covenants; establish the Executives’ duties and compensation; and provide for their continued employment with the Company. The discussion that follows summarizes certain other anticipated terms of these agreements.
Term. The initial term of each of the employment agreements commenced upon the closing of the Merger and continue for a term of three years in the case of Dr. Roberts and Dr. Pedder, and two years in the case of Mr. Maness, unless terminated sooner in accordance with the employment agreement (see “Termination” below). After the initial term expires, the employment agreements will automatically renew for successive one-year terms unless either the Company or the Executive provides written notice of their intent not to renew at least 90 days prior to the expiration of the then-current term.
Board Service. In the case of Drs. Roberts and Pedder, the Company will use commercially reasonable efforts to cause these individuals to be elected as members of the Company’s board of directors throughout the terms of their employment agreements.
Base Salary. The Company intends to pay each Executive a base salary at the following annual rates:
Dr. Roberts - $480,000
Dr. Pedder - $240,000
Mr. Maness - $240,000
These salaries will be reviewed by the board of directors from time to time and may be increased in the board of directors’ sole discretion. Salaries may not be reduced except in connection with an across-the-board reduction of executive-level salaries in which the Executive will not be subject to a greater reduction, on a percentage basis, than any other executive- level employee.
Bonus. For each calendar year, the Executives will be eligible to receive an annual bonus based on the following target amounts of each Executive’s base salary:
Dr. Roberts - 50%
Dr. Pedder - 30%
Mr. Maness - 30%
The actual amount of each annual bonus will depend on the level of achievement of the Company’s corporate objectives and the Executive’s individual objectives, in each case, as established by the board for the calendar year with respect to which such annual bonus relates. The annual bonus for a calendar year, to the extent earned, will be paid in a lump sum in the following calendar year. The annual bonus will not be deemed earned until the date that it is paid. Accordingly, in order for the Executive to receive an annual bonus, the Executive must be actively employed by the Company at the time of such payment.
Equity Compensation. Each Executive will be eligible to receive such equity grants or awards as may be approved by the board of directors in its discretion.
Subject to approval by the board of directors and the terms of the Company’s equity compensation plan then in place, in the event the Company issues additional securities raising aggregate funds of $10,000,000 (in one or more transactions), occurring, if at all, within two years following the Merger (the “Additional Financing Period”), the Company will grant each Executive options to purchase a number of shares of Common Stock of the Company (the “Anti-Dilution Options”) sufficient to ensure that their respective ownership immediately following the Additional Financing Period, on a fully diluted basis and assuming the exercise of all outstanding options (whether or not then exercisable) is equal to their respective ownership immediately following the Merger, as determined on a fully diluted basis and assuming the exercise of all outstanding options (whether or not then exercisable). The per share exercise price of the Anti-Dilution Options will be equal to the fair market value of a share of the Company’s Common Stock on the date of grant, as determined by the board of directors. The Anti-Dilution Options, if any, will become exercisable in four equal annual installments, in each case subject to the continued employment of each Executive with the Company on the date each such vesting milestone is achieved, and will be subject to the terms of the Company’s equity incentive plan then in place and a related option grant agreement to be entered between Executive and the Company.
Other Benefits. Dr. Roberts and Dr. Pedder will each be entitled to no less than 25 paid vacation days per year. Mr. Maness will be entitled to no less than 20 paid vacation days per year. The Executives will also be entitled to such other benefits, and to participate in such benefit plans, as are generally made available to similarly situated senior executive employees of the Company. The Company will also reimburse the Executives for all reasonable business expenses they incur in connection with the performance of their duties.
Termination. The employment agreements may be terminated in the following circumstances:
● Automatically effective upon the Executive’s death.
● By the Company upon notice to the Executive in the event of the Executive’s disability. “Disability” means the inability of the Executive to perform the essential functions of their job for 90 consecutive days or for 120 days in any one-year period due to the condition of the Executive’s physical, mental, or emotional health.
● By the Company for cause. “Cause” means the Executive’s (i) fraud, embezzlement or misappropriation with respect to the Company; (ii) willful or grossly negligent misconduct that has or may reasonably be expected to have a material adverse effect on the property, business, or reputation of the Company; (iii) material breach of their employment agreement; (iv) willful failure or refusal to perform their material duties or willful failure to follow any specific lawful instructions of the board of directors (in the case of Dr. Roberts and Dr. Pedder) or the chief executive officer (in the case of Mr. Maness); (v) conviction or plea of nolo contendere in respect of a felony or of a misdemeanor involving moral turpitude; or (vi) material failure to comply with the Company’s workplace rules, policies, or procedures.
● By the Company for any reason other than for cause or the Executive’s disability.
● By the Executive for good reason. “Good reason” means the occurrence of any of the following events without the Executive’s written consent: (i) the Company’s requiring the Executive to be based at any office or location more than 25 miles from their principal work location, except for travel reasonably required in the performance of the Executive’s responsibilities to the Company; (ii) a material reduction of the Executive’s base salary not in compliance with their employment agreement; (iii) a material diminution of the Executive’s authority, duties, or responsibilities; or (iv) the Company’s material breach of the Executive’s employment agreement. The Company will have an opportunity to cure any such conditions following notice by the Executive.
● By the Executive upon 30 days’ written notice to the Company at any time for any reason.
Separation Benefits Not in Connection with a Change in Control. If the Company terminates the Executive’s employment without cause or if the Executive resigns for good reason, in either case not in connection with a change in control of the Company, then the Executive will be entitled to the following benefits:
● 24 months of then-current base salary in the case of Dr. Roberts and Dr. Pedder, and 12 months of then-current base salary in the case of Mr. Maness.
● Continuation of health insurance coverage for the Executive and their family for 18 months in the case of Dr. Roberts and Dr. Pedder, and 12 months in the case or Mr. Maness, or until the Executive becomes eligible for coverage under another employer’s plan.
The Company’s obligation to provide such benefits is conditioned upon the Executive executing, and not revoking, a release of claims in a form acceptable to the Company.
Separation Benefits in Connection with a Change in Control. If the Company terminates the Executive’s employment without cause, or if the Executive resigns for good reason, in either case at the time of, or within six months following a change in control of the Company, then the Executive will be entitled to the following benefits:
● 24 months of then-current base salary in the case of Dr. Roberts and Dr. Pedder, and 12 months of then- current base salary in the case of Mr. Maness.
● Accelerated vesting of all equity awards such that all awards are deemed to have been vested as of the date of termination.
● Continuation of health insurance coverage for the Executive and their family for 18 months in the case of Dr. Roberts and Dr. Pedder, and 12 months in the case or Mr. Maness, or until the Executive becomes eligible for coverage under another employer’s plan.
The Company’s obligation to provide such benefits is conditioned upon the Executive executing, and not revoking, a release of claims in a form acceptable to the Company.
A “change in control” means the occurrence of any of the following events:
● Any “person,” including a “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) but excluding the Company, any entity controlling, controlled by or under common control with the Company, any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any such entity, and, with respect to any particular qualified participant of any equity incentive plan of the Company (a “Participant”), the Participant and any “group” (as such term is used in Section 13(d)(3) of the Exchange Act) of which the Participant is a member), is or becomes the “beneficial owner” (as defined in Rule 13(d)(3) under the Exchange Act), directly or indirectly, of securities of the Company representing 50% or more of either (i) the combined voting power of the Company’s then-outstanding securities; or (ii) the Company’s then-outstanding equity securities (in either such case other than as a result of an acquisition of securities directly from the Company).
● Any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own, directly or indirectly, equity securities representing in the aggregate 50% or more of the combined voting power of the securities of the entity issuing cash or securities in the consolidation or merger (or of its ultimate parent entity, if any).
● Any sale, lease, exclusive license, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company, other than a sale or disposition by the Company of all or substantially all of the Company’s assets to an entity, at least 50% of the combined voting power of the voting securities of which are owned by “persons” (as defined above) in substantially the same proportion as their ownership of the Company immediately prior to such sale.
● The members of the board at the beginning of any consecutive 24-calendar-month period (the “Incumbent Directors”) cease for any reason other than due to death to constitute at least a majority of the members of the board; provided that any director whose election, or nomination for election by the Company’s stockholders, was approved or ratified by a vote of at least a majority of the members of the board of directors then still in office who were members of the board of directors at the beginning of such 24-calendar-month period, will be deemed to be an Incumbent Director.
Indemnification. The Company will indemnify each Executive and hold them harmless in connection with the defense of any lawsuit or other claim to which they are made a party by reason of being an officer, director, or employee of the Company, to the fullest extent permitted by Delaware law. This indemnification obligation does not extend to claims arising out of the Executives’ willful misconduct. In addition, the Company will use commercially reasonable efforts to maintain directors’ and officers’ liability insurance for each Executive for acts and omissions occurring during Executive’s employment with the Company.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS.
The following table sets forth certain information with respect to the beneficial ownership of our Common Stock as of March 1, 2025 by:
● Each of our named executive officers;
● Each of our directors;
● All of our current directors and executive officers as a group; and
● Each person, or group of affiliated persons, who beneficially owned more than 5% of our Common Stock.
We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.
Transactions with Lucius Partners and Related Persons
On March 10, 2022, Unite Acquisition issued an aggregate of 5,000,000 shares of Common Stock to its sole stockholder, Lucius Partners, for an aggregate purchase price equal to $500, pursuant to the terms and conditions set forth in the Common Stock Purchase Agreement with Lucius Partners. The Company issued these shares of Common Stock under the exemption from registration provided by Section 4(a)(2) of the Securities Act.
Also on March 10, 2022, Unite Acquisition issued an unsecured promissory note to Lucius Partners, pursuant to which the Company agreed to repay Lucius Partners the sum of any and all amounts that Lucius Partners may advance to the Company on or before the date that the Company consummates a business combination with a private company or reverse takeover transaction or other transaction after which the Company would cease to be a shell company (as defined in Rule 12b-2 under the Exchange Act). The Company has used the proceeds from the note to cover its expenses. Interest did not accrue on the outstanding principal amount of the note except if an Event of Default (as defined in the note) has occurred. In the event of an Event of Default, the entire note shall automatically become due and payable (the “Default Date”), and starting from five days after the Default Date, the interest rate on the note shall accrue at the rate of 18% per annum. As of December 31, 2024 and December 31, 2023, the amount due under the note payable was $0 and $81,219, respectively.
Also effective March 10, 2022, Unite Acquisition entered into a services agreement with Lucius Partners, pursuant to which Unite Acquisition paid Lucius Partners a quarterly fee of $1,250 for advisory, accounting, and administrative support services. Unite Acquisition used the office space and equipment of its management under this agreement. This services agreement was terminated in connection with the Merger.
On October 28, 2024, Unite Acquisition issued an unsecured promissory note (the “October 2024 Note”) to Lucius Partners Opportunity Fund, LP (“LPOF”) and received $275,000. The annual interest rate on the promissory note is 12%. The note matures on October 28, 2025, and can be prepaid at any time without penalty. Unite Acquisition used the proceeds to pay off the note to Lucius Partners described above and the director fees owed to Mr. Pereira and other accrued expenses. The general partner of the new lender LPOF is Lucius Capital Partners LLC (“LCP”). The investment manager of LPOF is Lucius Capital Fund Management, LLC (“LCFM”). Lucius Partners, LCP and LCFM have two individuals in common as members, thus LPOF is considered a related party. The October 2024 Note was repaid in connection with the Merger.
On February 11, 2025, we entered into an Advisory Services Agreement with Lucius Partners, and agreed to pay to Lucius Partners a cash fee of $180,000 for advisory services during the first year following the closing of our private placement offering on February 11, 2025, and agreed to pay Lucius Partners for advisory services, in advance for four consecutive three-month periods, commencing on the first day of the month that is the first full month 12 months or more after such closing, a cash fee of $45,000 for one year (such two-year period, the “Advisory Period”). The Advisory Period can be renewed for additional one-year periods upon written request by the Company within 60 days prior to the expiry of any Advisory Period.
Policies and Procedures for Related Person Transactions
Our Audit Committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” as defined in applicable SEC rules and regulations. As provided in the Audit Committee charter, in approving or rejecting any such transaction, our Audit Committee is to consider the relevant facts and circumstances available and deemed relevant to it, including, among other factors, whether the terms or other aspects of the transaction differ from those that would likely be negotiated with independent third parties.
All of the transactions described in this section were entered into prior to the adoption of the Audit Committee charter. Although we have not had a written policy for the review and approval of transactions with related persons, our board of directors has historically reviewed and approved any transaction where a director or officer had a financial interest, including the transactions described above. Prior to approving such a transaction, the material facts as to the relationship or interest of the relevant related person in the agreement or transaction were disclosed to our board of directors. Our board of directors took this information into account when evaluating the transaction and in determining whether such transaction was fair to us and in the best interest of all our stockholders.

Audit-related fees(2) -- --
Tax fees(3) -- --
All other fees(4) -- --
Total $ 50,786 $ 32,035
(1) Audit fees consist of the aggregate fees billed for professional services rendered for the audit of Unite Acquisition’s annual financial statements and the reviews of the financial statements included in its Forms 10-Q and for any other services that were normally provided in connection with its statutory and regulatory filings or engagements.
(2) Audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of Unite Acquisition’s audit or review of its financial statements.

The policy provided that, without limiting the foregoing, the independent accounting firm would not be retained to provide services related to bookkeeping or other services related to the accounting records or financial statements, financial information systems design and implementation, appraisal or valuation services, fairness opinions or contribution-in-kind reports, actuarial services, internal audit outsourcing services, management functions, broker-dealer, investment adviser or investment banking services, legal services or expert services unrelated to the audit.
Audit Committee’s Pre-Approval Process
Unite Acquisition did not have a standing audit committee or a committee performing similar functions.
