- Completion of Enrollment in Zunsemetinib Phase 2b Trial in Rheumatoid Arthritis As Previously Announced; Data Expected in Q4 2023 -
“During the second quarter of this year, we continued to make positive strides across our clinical development pipeline, most notably through the completion of enrollment in our Phase 2b trial of zunsemetinib in patients with rheumatoid arthritis, which positions that trial to be our next Phase 2 data read-out,” stated
Research and Development Highlights:
- Zunsemetinib, an investigational oral small molecule MK2 inhibitor:
Currently being developed as a potential treatment for immuno-inflammatory diseases- Rheumatoid Arthritis (ATI-450-RA-202): This Phase 2b placebo-controlled dose ranging trial to investigate the efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of multiple doses (20 mg and 50 mg twice daily) of zunsemetinib in combination with methotrexate in subjects with moderate to severe rheumatoid arthritis (RA) completed enrollment in
June 2023 . Aclaris continues to expect topline data in the fourth quarter of 2023. - Psoriatic Arthritis (ATI-450-PsA-201): This Phase 2a placebo-controlled trial to investigate the efficacy, safety, tolerability, PK and PD of zunsemetinib (50 mg twice daily) in subjects with moderate to severe psoriatic arthritis (PsA) is ongoing. Aclaris continues to expect topline data in the first half of 2024.

- ATI-1777, an investigational topical “soft” Janus kinase (JAK) 1/3 inhibitor:
Currently being developed as a potential treatment for mild to severe atopic dermatitis (AD)
- Atopic Dermatitis (ATI-1777-AD-202): This Phase 2b vehicle-controlled trial to determine the efficacy, safety, tolerability, and PK of multiple doses and application regimens of ATI-1777 in subjects with mild to severe AD is ongoing. Aclaris continues to expect topline data in the second half of 2023.
- ATI-2138, an investigational oral covalent ITK/JAK3 inhibitor:
Currently being developed as a potential treatment for ulcerative colitis; Aclaris is also exploring additional indications for other T cell-mediated autoimmune diseases
Healthy Volunteers (ATI-2138-PKPD-102): This two-week Phase 1 MAD (multiple ascending dose) trial to investigate the safety, tolerability, PK and PD of ATI-2138 in healthy volunteers has been completed. Based on a preliminary analysis of the PK, PD and safety, Aclaris believes the data support the progression of ATI-2138 into Phase 2 clinical development in ulcerative colitis. Aclaris expects to report the data inSeptember 2023 .
- ATI-2231, an investigational oral MK2 inhibitor compound:
Currently being explored as a potential treatment for pancreatic cancer and metastatic breast cancer as well as in preventing bone loss in patients with metastatic breast cancer
- This is the second MK2 inhibitor generated from Aclaris’ proprietary KINect® drug discovery platform and is designed to have a long plasma half-life.
- Aclaris is supporting
Washington University in a first-in-human investigator-initiated Phase 1a trial of ATI-2231 in patients with advanced solid tumor malignancies. Aclaris expects clinical development activities to be initiated in the second half of 2023.

Financial Results
Second Quarter 2023
- Net loss was
$29.6 million for the second quarter of 2023 compared to$20.5 million for the second quarter of 2022. - Total revenue was
$1.9 million for the second quarter of 2023 compared to$1.5 million for the second quarter of 2022. The increase was driven by higher licensing revenue primarily from royalties earned on out-licensed intellectual property. - Research and development (R&D) expenses were
$25.3 million for the quarter endedJune 30, 2023 compared to$18.8 million for the prior year period.- The
$6.5 million increase was primarily the result of higher:- Zunsemetinib development expenses related to drug candidate manufacturing and costs associated with clinical activities for a Phase 2b trial for RA.
- ATI-2138 development expenses, including costs associated with a Phase 1 MAD trial and other preclinical activities.
- Compensation-related expenses due to an increase in headcount.
- The
- General and administrative (G&A) expenses were
$8.3 million for the quarter endedJune 30, 2023 compared to$6.1 million for the prior year period. The increase was primarily due to bad debt expense recorded from Aclaris’ determination that collection of amounts due fromEPI Health are uncertain as a result of their filing for Chapter 11 bankruptcy protection. Compensation-related expenses also increased due to an increase in headcount. - Licensing expenses were
$0.6 million for the quarter endedJune 30, 2023 resulting from separate third-party contractual obligations related to the non-exclusive patent license agreement withLilly . There were no licensing expenses for the quarter endedJune 30, 2022 . - Revaluation of contingent consideration resulted in a
$1.5 million gain for the quarter endedJune 30, 2023 compared to a gain of$3.4 million for the prior year period.
Year-to-date 2023

$47.9 million for the six months endedJune 30, 2023 compared to$33.1 million for the prior year period.- The
$14.8 million increase was primarily the result of higher:- Zunsemetinib development expenses, including costs associated with clinical activities for a Phase 2b trial for RA and a Phase 2a trial for PsA.
- ATI-2138 development expenses, including costs associated with a Phase 1 MAD trial and other preclinical activities.
- Compensation-related expenses due to an increase in headcount.
- The
- G&A expenses were
$17.1 million for the six months endedJune 30, 2023 compared to$12.2 million for the prior year period.- The
