Frequently asked questions about RCT2100

What is RCT2100 used for?

RCT2100 is an investigational small molecule being developed for cystic fibrosis. It is currently in Phase 2 clinical development. The drug is being studied in a randomized, double-blind, placebo-controlled trial that includes healthy participants and participants with cystic fibrosis.

Who makes RCT2100?

RCT2100 is being developed by cbdMD, Inc., a company traded on the NYSE American under the ticker symbol YCBD. The company is conducting a Phase 2 clinical trial of RCT2100 for cystic fibrosis.

What phase is RCT2100 in?

RCT2100 is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 2 trial is active but not recruiting participants, with a planned enrollment of 128.

What clinical trials is RCT2100 in?

RCT2100 is being evaluated in a Phase 2 study with the identifier NCT06237335. This randomized, double-blind, placebo-controlled trial is assessing the safety and tolerability of RCT2100 in healthy participants and in participants with cystic fibrosis. The study is being conducted in the United States, France, Netherlands, New Zealand, and the United Kingdom.

How does RCT2100 work?

RCT2100 is a small molecule that targets the cystic fibrosis transmembrane conductance regulator (CFTR) mRNA. It is designed to address the underlying cause of cystic fibrosis by modulating CFTR function. The drug is being studied in a biomarker-selected patient population.
