 drug resistance, and modulate the immune
system’s response to cancer.

Several companies are developing liposomal formulations
and other nanoparticle-based delivery systems designed to improve the delivery and efficacy of cancer drugs, including Merrimack Pharmaceuticals
and Celator Pharmaceuticals, that have developed liposomal platforms for chemotherapeutic agents. These platforms aim to enhance drug
accumulation in tumor tissues while minimizing systemic toxicity, similar to our ARB’s intended mechanism of action.

Additionally, AstraZeneca, Roche, and Merck are
advancing the development of therapies targeting the TME, particularly focusing on modulating the immune microenvironment and overcoming
the immunosuppressive barriers within solid tumors. These efforts include the development of novel immune checkpoint inhibitors and agents
targeting CAFs, ECM remodeling enzymes, and other components critical to TME dynamics.

Emerging biotech firms are also exploring innovative
approaches to TME normalization, such as the use of small molecule inhibitors, monoclonal antibodies targeting CAFs or ECM components,
and gene therapy approaches to modulate the TME. These therapies aim to improve the penetration and effectiveness of existing cancer treatments
and may provide direct competition to our ARB technology.

On the technological front, advancements in nanotechnology,
drug formulation, and targeted delivery mechanisms, including the use of targeting ligands and stimuli-responsive release systems, present
potential competition. These technologies aim to enhance the selective accumulation and controlled release of therapeutics within the
TME, which is a key feature of our liposomal ARB formulation.

Furthermore, the use of angiotensin receptor blockers
(ARBs) in cancer therapy, while innovative, is not exclusive to our company. Research institutions and pharmaceutical companies are investigating
the repurposing of ARBs and other similar agents for oncological applications, given their potential anti-tumor effects. This could lead
to direct competition with our ARB product candidate, especially if these entities develop formulations or combinations that demonstrate
superior efficacy or safety profiles. However, while other methods of delivering ARBs orally or intravenously may lower blood pressure,
making them unsuitable for a large portion of cancer patients, the liposomal ARB has been demonstrated in animal models to be safe without
reducing blood pressure. This allows for its potential administration in a safe and efficacious manner.

The competitive landscape in oncology is highly
dynamic, with continuous advancements in science and technology leading to the emergence of novel therapeutic modalities
