Impacts of COVID-19 on Our Business
The impacts of the global COVID-19 pandemic continue to evolve. We have implemented a hybrid work model of remote and in-person operations for our employees that enables us to continue to develop our drug candidates and provide contract research services to our clients. We are focused on ensuring the continuity of our operations.
If COVID-19 continues to spread, we may experience disruptions that could severely impact our business, results of operations and prospects, including the timing of our development programs and our clinical trials, including our trials of zunsemetinib as a potential treatment for moderate to severe rheumatoid arthritis and other immuno-inflammatory diseases and ATI-1777 as a potential treatment for moderate to severe atopic dermatitis, and the supply of active pharmaceutical ingredients and drug product for our clinical trials. The extent to which the COVID-19 pandemic impacts our business, our preclinical and clinical development and our regulatory efforts will depend on future developments that are highly uncertain and cannot be predicted, such as the spread of the disease, the introduction and spread of new variants, travel restrictions, quarantines, stay-at-home orders, social distancing requirements, business closures, staffing shortages, and supply chain and other disruptions in the United States and other countries, and the effectiveness of actions taken in the United States and other countries to contain and treat the disease, including the administration of vaccines. Accordingly, we do not know the full extent of the potential impacts on our business, our preclinical and clinical development and regulatory activities.
