ing to a new product candidate pipeline has many risks, including the ability to obtain sufficient capital to cover expenses to fund operations. These risks may be further exacerbated by the FYARRO Divestiture, as FYARRO has historically been our only source of revenue. The ADC Therapies represent a new preclinical pipeline with new targets and indications from historical current clinical pipeline and FYARRO. As a result, we have competitors that are better established in the market, have greater experience with such line of business or have greater resources than we do. Furthermore, certain of our current employees may have limited experience with discovery, research and development, preclinical studies and clinical trials relating to ADC Therapies and may have limited experience with respect to other programs we may explore as we seek to expand our pipeline. We may also be required to incur additional costs, including hiring additional personnel or equipment or engaging with new service providers. We may also have issues with the transfer of materials or learnings.

The ADC Therapies have never been tested in humans. They are comprised of antibodies that have never been tested in humans and linker-payloads that are currently in clinical trials run by independent third parties for other indications.

Our product candidates are next-generation ADC Therapies using the same linker-payload designed by Hangzhou DAC and new antibodies designed by WuXi Biologics. Though ADC-based product candidates have been or are currently being evaluated by others in clinical trials using similar targets or the same linker-payload architectures, our product candidates and their antibody components have never been evaluated in human clinical trials. If our product candidates encounter safety or efficacy problems, developmental delays or regulatory issues or other problems, such problems could impact the development plans for our other product candidates because all of our product candidates are currently use the same linker-payload architecture.

Additionally, if the ADC Therapies being developed by other third parties that use the same linker-payload as our product candidates encounter safety or efficacy problems, our product candidates may face challenges from a development, regulatory or commercialization perspective. Lack of efficacy, adverse events, undesirable side effects or other adverse results may emerge in clinical trials conducted by third parties investigating a similar product candidate or product candidates using the same or similar linkers, payloads or antibodies. Those adverse results can adversely affect the development, approval and commercialization of our product candidates.

Additionally, WuXi Biologics and Hangzhou DAC may enter into other licenses or collaboration partners that allow more third parties to develop and commercialize product candidates with the same or similar components, thereby
