Summary

RBN-3143 Background: PARP proteins are members of a family of seventeen ADP-ribosyltransferase (ART) enzymes that regulate cellular processes including gene expression, protein degradation, and multiple cellular stress responses. RBN-3143 is a PARP-14 inhibitor. PARP14 is over-expressed in tissues with inflammatory diseases. RBN-3143 is a novel, orally administered PARP14 inhibitor that was developed to be evaluated as therapy for a range of inflammatory diseases, with an initial focus on Atopic Dermatitis.

Study Overview: The study consists of 2 parts. Part A: This part of the study is being conducted in a clinical research unit (CRU) and is enrolling healthy adult subjects to determine the safety of RBN-3143; its absorption, metabolism, and excretion (what the body does to this drug); and will assess its potential pharmacodynamic properties (what the drug does to the body).

There are 3 subsections to this part of the study. The first segment was conducted in a double-blind manner (neither the investigator nor subject knew if placebo or RBN-3143 was given) to assess dosing regimens of RBN-3143 when taken in a fasted state (before food). The last two segments are currently recruiting and are Open Label (all subjects will receive RBN-3143) and will assess RBN-3143 when taken with food, with pantoprazole, a medication that decreases the amount of acid in the stomach, and with midazolam.

Part B: In early 2023 the second part of the study will be conducted in patients with moderate to severe atopic dermatitis to measure the pharmacodynamic activity of RBN-3143 and evaluate preliminary efficacy of 28 days administration of the study drug. All patients will receive the same dose of RBN-3143.
