WILMINGTON, Del. - May 2, 2023 - Incyte (Nasdaq INCY) today reports 2023 first quarter financial results, and provides a status update on the Company's clinical development portfolio.

Our first quarter results demonstrate continued year-over-year double-digit revenue growth driven by Jakafi, which grew across all indications, and Opzelura, which is on track to become one of the most successful dermatology launches in recent years. In addition, we further expanded our commercial portfolio with several regulatory approvals including Opzelura for vitiligo in Europe." said Herv Hoppenot, Chief Executive Officer, Incyte. Furthermore, in Q1 we made a decision to focus our development efforts on eight programs that have high potential value for us and discontinued six other programs. This allows us to optimize our allocation of resources on programs that can have a high impact for patients and for Incyte.

Key Product Sales Performance

Net product revenues of $580 million

Net product revenues grew 7% compared with the first quarter of 2022, driven by strong underlying patient demand growth (+7% Y Y) including an 8% growth in new patients. Total patients grew across myelofibrosis (MF), polycythemia vera (PV) and graft-versus-host disease (GVHD).

Net product revenues were unfavorably impacted by

Higher gross-to-net deductions, compared to fourth quarter of 2022, as a result of the Medicare coverage gap and higher commercial patient deductibles at the beginning of the plan year, as well as an increase in 340B orders.

Lower than normal levels of channel inventory at the end of Q1, representing an $11 million impact.

Net product revenues of $57 million

Net product revenues grew 343% compared with the first quarter of 2022, driven by growth in patient demand and expansion in payer coverage as the launch in atopic dermatitis (AD) and vitiligo continues.

Compared to the fourth quarter of 2022, net product revenues were unfavorably impacted by

Increase in co-pay assistance due to higher commercial patient deductibles at the beginning of the plan year, consistent with first quarter dynamics and higher Medicaid utilization volume.

Acceleration of refills in December 2022 driven by patient demand in advance of annual deductible reset or health plan changes that negatively impacted refills during the months of January and February this year.

MPNs and GVHD - key highlights

LIMBER (Leadership In MPNs and GVHD BEyond Ruxolitinib) Our LIMBER development program encompasses multiple monotherapy and combination strategies, with the goal of improving upon the standard of care in MF, PV, GVHD and now, essential thrombocythemia (ET).

Combination trials of ruxolitinib BID with zilurgisertib (ALK2) and INCB57643 (BET) are ongoing and progressing well.

In early development, INCA33989 (mCALR) is on track for initiating first-in-human study in MF and ET in 2023. Additionally, a Phase 1 study evaluating ruxolitinib BID in combination with Cellenkos' CK0804 in MF is continuing to recruit patients.

AGAVE-201, a global pivotal Phase 2 trial of axatilimab in patients with cGVHD is ongoing and results are on track for mid-2023. A Phase 1 2 combination trial of axatilimab in combination with ruxolitinib is being planned.

The Phase 3 LIMBER-304 trial, evaluating parsaclisib in combination with ruxolitinib BID in suboptimal responders in MF and the Phase 3 LIMBER-313 trial, evaluating parsaclisib in combination with ruxolitinib BID in first-line MF, were discontinued following results of interim analyses that indicated that the studies were unlikely to meet their primary endpoints in the intent-to-treat patient population. The studies were not stopped due to safety.

The U.S. Food and Drug Administration (FDA) issued a complete response letter for ruxolitinib extended-release (XR) tablets for once-daily (QD) use in the treatment of certain types of MF, PV and GVHD. Incyte will work with the FDA to determine appropriate next steps.

1 Development collaboration with Cellenkos, Inc.

2 Clinical development of axatilimab in GVHD conducted in collaboration with Syndax Pharmaceuticals.

Other Hematology Oncology - key highlights

Zynyz (retifanlimab-dlwr) approved for Merkel cell carcinoma in the U.S. Zynyz, a humanized monoclonal antibody targeting programmed death receptor-1 (PD-1), received accelerated approval for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma (MCC) in the U.S. This represents the first regulatory approval for Incyte's PD-1 inhibitor, which is also being evaluated in pivotal trials in non-small cell lung cancer (NSCLC) and squamous cell carcinoma of the anal canal (SCAC).

Monjuvi (tafasitamab-cxix) Minjuvi (tafasitamab) Minjuvi continues to launch in new ex-US markets, having gained reimbursement in two additional countries this quarter, bringing the total of launch markets to six. At the American Association for Cancer Research (AACR), final five-year follow-up data from the Phase 2 L-MIND study were presented, which showed that Monjuvi plus lenalidomide followed by Monjuvi monotherapy provided prolonged, durable responses in adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).

Pemazyre (pemigatinib) continues to expand in ex-U.S. markets in cholangiocarcinoma and myeloproliferative neoplasms (MLNs) Pemazyre was approved in Japan by the Japanese Ministry of Health, Labour and Welfare (MHLW) for the treatment of MLNs with FGFR1 fusion. MLNs are a rare, aggressive group of cancers characterized by an over-production of myeloid cells, or bone tissue, with the tendency to rapidly progress to an acute myeloid leukemia (AML). The launch of Pemazyre in cholangiocarcinoma (CCA) is ongoing in 10 key markets in Europe. In clinical development, FIGHT-210, evaluating pemigatinib in NSCLC, was discontinued.

Parsaclisib in warm autoimmune hemolytic anemia (wAIHA) Based on the challenging regulatory landscape associated with the PI3K class, development of parsaclisib in wAIHA has been discontinued.

2 Retifanlimab licensed from MacroGenics.

3 Clinical trial collaboration and supply agreement with Mirati Therapeutics.

Inflammation and Autoimmunity (IAI) - key highlights

Opzelura approved for vitiligo in Europe Opzelura was approved by the European Commission for the treatment of non-segmental vitiligo with facial involvement in adults and adolescents 12 years of age and older. The EC decision is based on data from two pivotal Phase 3 clinical trials (TRuE-V1 and -V2), which showed treatment with Opzelura resulted in significant improvements in facial and total body repigmentation versus vehicle at Week 24 and among completers of an open-label extension at Week 52. Opzelura was well-tolerated with no serious treatment-related adverse events related to ruxolitinib cream.

Opzelura 104-week safety and efficacy data in vitiligo provide insights into the value of long-term treatment 104-week results from the long-term extension of the Phase 3 TRuE-V study were presented at the American Academy of Dermatology (AAD) Annual Meeting. The data demonstrated that many patients who achieved a high level of facial repigmentation ( F-VASI90) at Week 52 were able to maintain durable response one year following withdrawal of treatment. In patients who did not achieve F-VASI90 at Week 52 and continued treatment with Opzelura, improvements in facial and total body repigmentation, as shown by greater proportions of patients reaching F-VASI75 and T-VASI50, were observed through Week 104.

Ruxolitinib cream in pediatric atopic dermatitis (AD) A Phase 3 trial of ruxolitinib cream in pediatric AD has completed enrollment with results expected by end of year. There are an estimated 2-3 million pediatric AD patients (ages 2-11) in the United States.

Ruxolitinib cream in other indications Incyte continues to expand the development of ruxolitinib cream into new indications as we seek to maximize the potential opportunity with the franchise. Phase 2 trials evaluating ruxolitinib cream in mild to moderate hidradenitis suppurativa (HS), lichen planus (LP) and lichen sclerosus (LS) are ongoing. Additionally, two Phase 3 trials evaluating ruxolitinib cream in prurigo nodularis (PN) were initiated.

Phase 2 results in hidradenitis suppurativa 52-week results from the Phase 2 study evaluating povorcitinib (15mg QD, 45mg QD, 75mg QD) in HS were presented as an oral presentation at the European Hidradenitis Suppurativa Foundation (EHSF) Annual Meeting. The data demonstrated that continuation of treatment with povorcitinib 75 mg resulted in sustained and durable efficacy across all treatment arms, and importantly, 22-29% of patients treated for 52-weeks achieved HiSCR100, which is defined as a 100% reduction from baseline in total abscess and nodule (AN) count with no increase from baseline in abscess or draining tunnel count. Povorcitinib is currently in two Phase 3 studies in moderate to severe HS.

Phase 2 results in vitiligo 36-week results from the Phase 2b study evaluating povorcitinib in patients with extensive vitiligo were presented as an oral late-breaking presentation at the American Academy of Dermatology (AAD) Annual Meeting. The data demonstrated that treatment with oral povorcitinib was associated with substantial total body repigmentation in patients with extensive nonsegmental vitiligo, as measured by total Vitiligo Area Scoring Index (T-VASI) scores. Specifically, the study met its primary endpoint, and patients receiving povorcitinib experienced statistically superior improvements in T-VASI at Week 24 compared to placebo (povorcitinib 15 mg, -19.1% 45 mg, -17.8% 75 mg, -15.7% vs. placebo, +2.3% least squares mean LSM difference, P 0.01). Incyte plans to move into Phase 3 development for povorcitinib in vitiligo, pending FDA regulatory discussions.

Studies planned for asthma and chronic spontaneous urticaria Incyte announced the expansion of povorcitinib development into other inflammatory and autoimmune diseases, including planning for two Phase 2 trials in asthma and chronic spontaneous urticaria.

1Novartis' rights to ruxolitinib outside of the United States under our Collaboration and License Agreement with Novartis do not include topical administration.

Discovery and other early development - key highlights

INCB123667 (CDK2) oral presentation at the American Association for Cancer Research (AACR) 2023 INCB123667 is a selective and potent CDK2 kinase inhibitor, which has been shown to suppress tumor growth as monotherapy and in combination with standard of care, in Cyclin E amplified tumor models, in vivo. At AACR, Incyte presented data demonstrating INCB123667 exhibited significant single-agent activity in vivo in CCNE1high breast cancer xenograft and patient-derived xenograft models. INCB123667 is currently being evaluated in a Phase 1 clinical trial in patients with advanced malignancies including CCNE1high TNBC and HR+HER2- tumors post-CDK4 6 inhibitors.

INCA33890 (TGF R2xPD-1) in clinical development INCA33890 is a TGF R2xPD1 bispecific antibody which has been engineered to avoid the known toxicity of broad TGF pathway blockade. INCA33890 has higher affinity for PD1 than TGF R2, and blocks TGF -signaling specifically in cells co-expressing PD-1, thus potentially sparing tissues where TGFb-signaling is important for normal function. Preclinical in vivo data presented at AACR show that INCA33890 has a greater anti-tumor effect than either individual benchmark antibodies or a simple combination of these.

Development of the adenosine program (including INCB106385 and INCA00186), INCAGN1876 (GITR) and INCB81776 (AXL MER) has been discontinued based on early efficacy data.

2023 First Quarter Financial Results

The financial measures presented in this press release for the three months ended March 31, 2023 and 2022 have been prepared by the Company in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), unless otherwise identified as a Non-GAAP financial measure. Management believes that Non-GAAP information is useful for investors, when considered in conjunction with Incyte's GAAP disclosures. Management uses such information internally and externally for establishing budgets, operating goals and financial planning purposes. These metrics are also used to manage the Company's business and monitor performance. The Company adjusts, where appropriate, for expenses in order to reflect the Company's core operations. The Company believes these adjustments are useful to investors by providing an enhanced understanding of the financial performance of the Company's core operations. The metrics have been adopted to align the Company with disclosures provided by industry peers.

Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used in conjunction with and to supplement Incyte's operating results as reported under GAAP. Non-GAAP measures may be defined and calculated differently by other companies in our industry.

As changes in exchange rates are an important factor in understanding period-to-period comparisons, Management believes the presentation of certain revenue results on a constant currency basis in addition to reported results helps improve investors' ability to understand its operating results and evaluate its performance in comparison to prior periods. Constant currency information compares results between periods as if exchange rates had remained constant period over period. The Company calculates constant currency by calculating current year results using prior year foreign currency exchange rates and generally refers to such amounts calculated on a constant currency basis as excluding the impact of foreign exchange or being on a constant currency basis. These results should be considered in addition to, not as a substitute for, results reported in accordance with GAAP. Results on a constant currency basis, as the Company presents them, may not be comparable to similarly titled measures used by other companies and are not measures of performance presented in accordance with GAAP.

1.Percentage change in constant currency is calculated using 2022 foreign exchange rates to recalculate 2023 results.

Product and Royalty Revenues Product and royalty revenues for the three months ended March 31, 2023 increased 11% over the prior year comparative period as a result of net product revenues increasing 14% year-over-year, primarily driven by increases in Jakafi and Opzelura net product revenues. The increase in Jakafi net product revenues was primarily driven by growth in patient demand across all indications and was partially offset by higher gross-to-net deductions for Medicare and commercial co-pay assistance consistent with historical prior years' first quarters, as well as an increase in 340B volumes. The quarter was also impacted by lower weeks on hand channel inventory than normal due to timing of certain customer purchases. Opzelura net product revenues for the quarter were $57 million, representing a 343% increase year-over-year driven by increased patient demand and expanded coverage. The quarter was negatively impacted by an increase in co-pay assistance due to higher commercial patient deductibles at the beginning of the plan year and higher Medicaid utilization volume. In addition, volume was negatively impacted by an acceleration of refills in December 2022 driven by patient demand in advance of annual deductible reset or health plan changes. Jakavi and Olumiant royalties for the quarter were impacted by unfavorable changes in foreign currency exchange rates, while Olumiant royalties were also impacted by a decrease in net product sales of Olumiant for use as a treatment for COVID-19.
