Note 1 – Organization and Description of the Business

Business Activities and Organization

We are a clinical-stage biopharmaceutical company focused on the development of drug products that are intended to provide treatment for patients who have a high unmet medical need condition that effects survival or the patient’s quality of life and have few or no treatment options. We currently have three drugs in various stages of clinical development. Our most advanced product candidate, PCS499, is an oral tablet that is a deuterated analog of one of the major metabolites of pentoxifylline (PTX or Trental^®). We have completed a Phase 2A trial for PCS499 and will begin recruiting for a Phase 2 trial in the first half of 2021. In addition, we have in-licensed PCS6422 (eniluracil) from Elion Oncology and PCS12852 from Yuhan Corporation. PCS6422 will be orally administered with capecitabine in a Phase 1B dose-escalation study in patients with Advanced Refractory Gastrointestinal (GI) Tract Tumors, with recruitment beginning in the first half of 2021. PCS12852 has already been evaluated in clinical studies in South Korea and we anticipate a response back to our pre-IND meeting questions by March 31, 2021. Our remaining two drug assets whose active molecules have been shown to be clinically efficacious require more toxicology data in order to more efficiently develop the drugs clinically.

Impact of COVID-19

The extent of the impact of the COVID-19 pandemic on our business, operations and development timelines and plans remains uncertain, and will depend on certain developments, including the duration of the outbreak and its impact on our development activities, planned clinical trial enrollment, future trial sites, CROs, third-party manufacturers, and other third parties with whom we do business, as well as its impact on regulatory authorities and our key scientific and management personnel. During 2020, although we modified our operations and practices due to the COVID-19 pandemic and to comply with federal, state and local requirements, our business, operations and development timelines were not materially adversely affected. However, the extent to which the COVID-19 pandemic may affect our business, operations and development timelines and plans in the future, including the resulting impact on our expenditures and capital needs, remains uncertain.
