The incidence of adverse events will be evaluated from the time of signing of the informed consent until approximately 2 weeks after the last dose of study drug. Examples of potential adverse events include: respiratory symptoms, liver toxicity, and skin conditions. Study participants will be monitored for adverse events via the following: vital signs (blood pressure assessed using a sphygmomanometer, temperature assessed by thermometer, pulse and respiratory rate assessed by pulse oximeter), oxygen saturation, spirometry, physical exams, blood chemistry, and quality of life assessments.
