ClinConnect Summary

This clinical trial, called PROT-001, is a Phase 1 study that aims to evaluate the safety and effects of a new medication in healthy adults. Specifically, the trial will look at how well the medication is tolerated, how it moves through the body, and how factors like age and food might affect its behavior. The study will involve different groups of participants, and it is designed to ensure that we learn as much as possible about the medication's effects before it is tested in people with specific health conditions.

To be eligible for this trial, participants must be healthy adults aged 18 to 65, or between 65 and 75 for one part of the study that focuses on older adults. They should also meet certain health criteria, such as having a specific body weight and not having any significant medical conditions. Participants will be closely monitored during the study, and they can expect to take the medication in a controlled environment. It's important to note that the trial is not yet recruiting participants, and those interested will need to provide informed consent before joining.

• • 10. Participants, who, in the opinion of the Investigator, can and will comply with the requirements and restrictions, including lifestyle restrictions listed in the Protocol.
• • 11. Able to swallow an oral solid-dosage form of medication.
• • 12. For Part 3 (Food-Effect study) only, able to consume a standardized high-fat meal.
• Exclusion Criteria:
• • 1. History or current evidence of a clinically significant or uncontrolled underlying condition, including but not limited to cardiovascular, hepatic, renal, hematological, infectious, autoimmune, neurological, psychiatric, endocrine, gastrointestinal, reproductive, pulmonary, or ocular. Clinically significant is defined as any disease that, in the opinion of the Investigator, would put the safety of the participant at risk through participation or which could affect the endpoint analysis if the disease/condition worsened during the study. EXCEPTION: Fully resolved childhood asthma is not exclusionary.
• • 2. History of or current invasive malignancy including hematological malignancies. Participants with a history of basal cell or squamous cell carcinoma or other carcinomas in situ that has been treated with no evidence of recurrence within 1 year prior to Screening will be allowed for inclusion, as judged by the Investigator.
• • 3. History or presence of any disease or condition known to interfere with the absorption, distribution, metabolism, or excretion of drugs.
• • 4. Any current active infections, including localized infections, or any recent history of active infections, cough, or fever within 1 week prior to IP administration (including severe acute respiratory syndrome coronavirus 2 \[SARS-CoV-2\]), or any history of recurrent or chronic infections.
