A Phase 2, multicenter, adaptive 2-part clinical trial designed to evaluate the safety and efficacy of ADX-629 alone and in combination with standard-of-care in adults with atopic dermatitis.

The trial is divided into 2 parts; the first part of the trial (Part 1) is open label, and the second part (Part 2) is randomized, double-blind, and placebo controlled.

In Part 1, approximately 10 subjects will receive open-label ADX-629 twice daily for 90 days.

In Part 2, approximately 40 subjects will be randomized to receive either ADX-629 or matching placebo twice daily for 90 days.

Patients who are interested in participating will be provided detailed information about the study including description of study assessments/procedures, possible side-effects, alternative treatments, and potential benefits.

• Not pregnant, breastfeeding, or lactating and agree to use a highly effective method of acceptable contraceptive for the trial duration, if applicable

Exclusion Criteria:

• Presence of clinically significant kidney disease or an estimated gloverular filtration rate (eGFR) of less than or equal to 45 milliliters/min/1.73 m2 during screening
• History of any unstable chronic diseases/conditions, clinically significant abnormalities, or findings, that in the opinion of the Investigator, could compromise subject safety or affect the conduct of the trial

Part 1 is an open-label trial.
