Westlake Village, CA, August 14, 2024 – Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today reported financial results for the quarter ended June 30, 2024, and provided a business update.

“In the second quarter, sales grew by a robust 43% sequentially, highlighting the strength of physician demand for ZORYVE across multiple approved indications, and our ability to continue to improve our GTN. Following the recent launch of ZORYVE cream for atopic dermatitis, we are well-positioned to drive further growth,” said Frank Watanabe, president and chief executive officer. “Our ZORYVE franchise co-promotion agreement with Kowa will further expand our total addressable market, allowing us to address millions of patients treated outside of a dermatology office. In addition, we continue to advance ZORYVE's late-stage development, with the filing of the supplemental new drug application for ZORYVE foam in scalp and body psoriasis, which will enable us to drive greater preference share, once approved.

Finally, we amended our existing debt agreement favorably, providing us with additional financial flexibility and improved liquidity to enhance our business going forward.”

“We are pleased that we continued to grow sales while prudently managing operating expenses in the second quarter. These solid financial results together with our amended existing debt agreement, which provides an extended maturity, a lower interest rate and the flexibility to repay a portion and re-draw it later, give us additional financial and strategic flexibility to continue investing in our growth, especially supporting our three commercial launches and advancing our pipeline,” said David Topper, chief financial officer.

ZORYVE cream - a highly potent and selective phosphodiesterase-4 (PDE4) inhibitor in a once-daily cream formulation, approved in the United States for the treatment of plaque psoriasis and atopic dermatitis

•U.S. Demand for ZORYVE cream in plaque psoriasis continues to grow, with over 252,000 prescriptions filled to date since launch by close to 13,000 unique prescribers, reflecting the high levels of patient and physician satisfaction with the ZORYVE cream clinical profile. ZORYVE cream is covered by the three largest Pharmacy Benefit Managers (PBMs) and multiple other commercial insurers, and the Company obtained its first Medicaid coverage in Texas, Florida, and New York and anticipates it will obtain Medicaid coverage in additional states during 2024. The cream 0.3% saw further GTN improvement in the second quarter compared to Q1 '24, and we anticipate modest incremental GTN improvement throughout 2024 as GTN for the cream 0.3% approaches steady state.

•The FDA approved ZORYVE cream 0.15% for the treatment of mild to moderate atopic dermatitis in adults and children down to age 6 in early Q3, and the Company commenced the commercial launch at the end of July. ZORYVE cream 0.15% is already covered as a line extension by two of the largest national PBMs, and the company anticipates continued improvement in coverage through the remainder of 2024.

•The launch of ZORYVE foam in seborrheic dermatitis continues to progress well, with over 98,000 prescriptions filled since launch, reflecting the high unmet need in this disease. ZORYVE foam is also covered by the three largest PBMs, and coverage for the foam is steadily improving, as evidenced by its favorable GTN, which is expected to improve over the remainder of 2024 and approach steady state in early 2025.

•The Company submitted an sNDA for ZORYVE foam for scalp and body psoriasis to the FDA in July 2024 based on the positive results from the pivotal ARRECTOR Phase 3 trial and a Phase 2b trial.

•In December 2022, Arcutis announced the enrollment of the first healthy volunteer subject in a Phase 1b study in alopecia areata. The first subject in the alopecia areata cohort enrolled in the second quarter of 2023.

•In July, the Company Received FDA approval for ZORYVE cream 0.15%, for the treatment of atopic dermatitis in adults and children down to age 6, and launched ZORYVE cream for atopic dermatitis in United States in late July.

•In July, the Company also announced a co-promotion agreement with Kowa Pharmaceuticals America, Inc., whereby Kowa will leverage its 200-person primary care sales force in the United States to market and promote ZORYVE cream and ZORYVE foam to primary care practitioners and pediatricians for all FDA approved indications.

•Amended the $200 million term-loan with SLR Investment Corp., lowering the interest rate by 150 basis points, extending the maturity to June 2029, and obtaining an option to prepay up to $100 million of the principal and re-draw it within 21-24 months at company’s discretion.

•Arcutis obtained five new U.S. patents in June and July related to ZORYVE. These patents cover, in part, formulations and methods of treatment resulting in unexpected and beneficial properties of ZORYVE, including the reduced side effects of ZORYVE compared to orally administered roflumilast and the beneficial pharmacokinetic profile of ZORYVE.

Product revenues for the quarter ended June 30, 2024 were $30.9 million compared to $4.8 million for the corresponding period in 2023. Revenues for the quarter were $17.3 million for ZORYVE cream 0.3% and $13.6 million for ZORYVE topical foam, 0.3%. Year-over-year and quarter-over-quarter increases were due to strong unit demand as well as GTN improvements. Across ZORYVE cream and ZORYVE foam, blended GTN is now in the high 50s, driven by the high percentage of prescriptions being reimbursed.

Cost of sales for the quarter ended June 30, 2024 were $3.5 million compared to $0.8 million for the corresponding period in 2023.

Research and development (R&D) expenses for the quarter ended June 30, 2024 were $19.3 million compared to $25.2 million for the corresponding period in 2023. The year-over-year decrease was due to decreased clinical development costs related to our topical roflumilast program.
