Companies Aclaris Therapeutics Inc FollowNov 13 (Reuters) - Aclaris Therapeutics (ACRS.O) on Monday said it would stop development of its rheumatoid arthritis treatment after it failed in a mid-stage trial, sending its shares plunging 84% before the bell. The trial tested two doses of the drug, zunsemetinib, along with anti-rheumatic drug methotrexate compared to placebo and methotrexate in patients with moderate to severe rheumatoid arthritis who have inadequate response to methotrexate alone. There was no notable differentiation between zunsemetinib and placebo across any measures of efficacy at 12 weeks, the company said. The company will also be halting enrollment in an ongoing mid-stage trial studying the drug in psoriatic arthritis. The drug developer said it is also studying its drug ATI-1777 in patients with moderate to severe atopic dermatitis which is currently in mid-stage trial.

Evercore ISI initiated coverage of Aclaris Therapeutics , a clinical stage biotech working on immunology and inflammation drugs, at an outperform, saying the market is underpricing its odds for success heading into the release of clinical trial data. Admittedly, the upcoming trial results may not be successful, which makes the bet a risky one, he said. If Aclaris is successful with zunsemetinib, it will be the only MK2 inhibitor on the market for rheumatoid arthritis, which Evercore ISI sees as an advantage. A similar drug from Bristol Myers Squibb wasn't successful in a different form of arthritis. Evercore ISI expects investors are only pricing in a 20% chance of positive data from the clinical trial, whereas the firm expects the odds are closer to 50%.

Companies Aclaris Therapeutics Inc FollowMarch 6 (Reuters) - Aclaris Therapeutics Inc (ACRS.O) said on Monday its experimental drug failed to meet the main goal of a mid-stage study to treat a painful skin disorder, sending its shares tumbling more than 36% in premarket trading. The drug, zunsemetinib, did not meet the main goal of reducing abscesses in patients with moderate to severe hidradenitis suppurativa (HS) at week 12, compared with a placebo. HS is a chronic inflammatory skin condition that causes abscesses and scarring on the skin. The study also failed to meet its secondary goals, which included percentage of patients who achieved at least a 50% reduction in number of inflammatory lesions, Aclaris said. The drug is being tested to treat other inflammatory conditions such as rheumatoid arthritis and psoriatic arthritis, far bigger markets than HS.
Shares of Aclaris Therapeutics can surge more than 60% on the back of a possible new treatment for immuno-inflammatory diseases, including rheumatoid arthritis, according to Goldman Sachs. Analyst Corinne Jenkins initiated coverage of Aclaris Therapeutics with a buy rating, saying she expects promising results out of clinical trials for the company's drug called zunsemetinib . The biopharma stock has already outperformed this year, up nearly 5% in 2022, while the S & P 500 declined roughly 14%. The analyst expects that there will be further catalysts for positive upside as the Aclaris unveils further data for zunsemetinib in 2023. "We see this profile as sufficient to garner modest share in these large indications, fostering a sizable peak sales opportunity which we estimate at > $5B across indications," Jenkins wrote.
