WAYNE, PA, USA I April 25, 2019 I Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a physician-led biopharmaceutical company focused on immuno-inflammatory and dermatological diseases, today announced that it has submitted an Investigational New Drug (IND) Application to the U.S. Food and Drug Administration (FDA) for ATI-450, an oral MK2 inhibitor, for the treatment of rheumatoid arthritis (RA). If the IND is allowed by the FDA, Aclaris plans to initiate a Phase 1 clinical trial of ATI-450 in the second half of 2019. 

“We are very pleased to have this IND under review by the FDA,” said Dr. Neal Walker, President & Chief Executive Officer of Aclaris.  “We look forward to beginning the development of ATI-450 as a potential treatment for rheumatoid arthritis and other potential indications driven by TNFα, IL-1β, IL-6, or IL-8. We believe there is an important need to provide additional treatment options for rheumatoid arthritis to improve overall patient care.”

ATI-450, an investigational medicine formerly known as CDD-450, would be the first novel compound created by Confluence Discovery Technologies, Inc., our indirect wholly owned subsidiary, to enter the clinical phase of development. Aclaris plans to initiate a Phase 1 single ascending dose study of safety, tolerance, and pharmacokinetics followed by several cohorts of multiple ascending doses. Aclaris is actively considering additional indications for clinical testing in the future.

Dosed orally, ATI-450 is a novel, selective MK2 (mitogen-activated protein kinase-activated protein kinase 2; MAPKAPK2) pathway inhibitor. MK2 is a key regulator of pro-inflammatory mediators including TNFα, IL-1β, IL-6, IL-8 and other essential pathogenic signals in chronic inflammatory and autoimmune diseases, as well as in cancer.  Selective MK2 pathway inhibitors are being investigated for their potential ability to block inflammatory cytokine production and activity and, thereby, restore balance to the body’s immune system. Selective MK2 pathway inhibitors are also being evaluated in cancer models for their ability to block stromal inflammation and affect cell-cycle checkpoint activity.  MK2 pathway inhibitors have the potential to treat patients with a variety of inflammatory and autoimmune diseases, as well as cancer. As an oral drug candidate, ATI-450 is being developed as a potential alternative to anti-TNF/anti-IL-1 biologics.

About Rheumatoid Arthritis

RA is the most common form of autoimmune arthritis. It affects more than 1.3 million Americans. About 75% of RA patients are women, and 1–3% of women may get rheumatoid arthritis in their lifetime. The disease most often begins between the ages of 30 and 50, and is a chronic disease which causes joint pain, stiffness, swelling, and decreased movement of the joints. Small joints in the hands and feet are most commonly affected, but RA can affect organs, such as eyes, skin or lungs.
