Regulus Therapeutics Inc (NASDAQ:RGLS) just announced that the FDA is placing a clinical hold on its lead hepatitis candidate, RG-101, and the company is selling off as a direct result of the announcement. After hours trading saw the company lose nearly 50% on it’s Monday morning open. Given yesterday’s volume, chances are we will see further decline today. Regulus was already down more than 40% on the year before the clinical hold came into force, and the latest development has only served to put more pressure on the company’s market capitalization. Among all the noise, however, there may be an opportunity.
