Incyte Reports 2021 Second Quarter Financial Results

and Provides Updates on Key Clinical Programs

Conference Call and Webcast Scheduled Today at 8:00 a.m. EDT

WILMINGTON, Del. - August 3, 2021 - Incyte (Nasdaq:INCY) today reports 2021 second quarter financial results and provides a status update on the Company's development portfolio.

"In the second quarter, we saw an acceleration of growth of Jakafi (ruxolitinib) and encouraging uptake in Europe for Pemazyre (pemigatinib). In addition, the recent positive CHMP opinion for tafasitamab and the potential subsequent launch of tafasitamab (Minjuvi ) in Europe represents another significant growth opportunity for Incyte," stated Herv Hoppenot, Chief Executive Officer, Incyte. "We continue to achieve clinical development success across our portfolio with positive outcomes from multiple programs, including topline results from ruxolitinib cream's pivotal trials in vitiligo (TRuE-V), 52-week safety and efficacy data of ruxolitinib cream in atopic dermatitis (TRuE-AD), Phase 2 data of parsaclisib in autoimmune hemolytic anemia (AIHA) and the achievement of bioequivalence with once-daily (QD) ruxolitinib."

MPNs and GVHD - key highlights

Ruxolitinib in GVHD: Data from the REACH3 trial of ruxolitinib versus best available therapy (BAT) in patients with steroid-refractory chronic graft-versus-host disease (GVHD) have been published in The New England Journal of Medicine. The supplemental New Drug Application (sNDA) seeking approval of ruxolitinib for the treatment of steroid-refractory chronic GVHD is under review; the Prescription Drug User Fee Act (PDUFA) date was extended to September 22, 2021.

LIMBER (Leadership In MPNs BEyond Ruxolitinib): Bioavailability and bioequivalence data were published for ruxolitinib's QD extended release (XR) formulation at the European Hematology Association (EHA) 2021 Virtual Congress. QD ruxolitinib is in stability testing with an NDA submission planned for early 2022. Clinical studies evaluating ruxolitinib in combination with parsaclisib, INCB57643 (BET) and INCB00928 (ALK2), are progressing as expected.

Updated interim data from the proof-of-concept trial evaluating parsaclisib in combination with ruxolitinib in myelofibrosis (MF) patients with an inadequate response to ruxolitinib monotherapy were also presented at EHA.

Other Hematology/Oncology - key highlights

Tafasitamab: In June, Incyte and MorphoSys announced that the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion recommending the conditional marketing authorization of tafasitamab in combination with lenalidomide, followed by tafasitamab monotherapy, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not eligible for autologous stem cell transplantation (ASCT).

Updated three-year data from the Phase 2 L-MIND study evaluating tafasitamab in combination with lenalidomide as a treatment for adult patients with relapsed or refractory DLBCL were presented at EHA. Multiple studies evaluating tafasitamab as a backbone therapy in various combinations for the treatment of patients with DLBCL, follicular lymphoma, marginal zone lymphoma and other B-cell malignancies are underway, including two Phase 3 trials (inMIND and frontMIND) currently ongoing. An additional proof of concept trial (coreMIND) of tafasitamab in combination with parsaclisib for the treatment of patients with relapsed or refractory chronic lymphocytic leukemia (CLL) is expected to start in the next six months.

Pemigatinib: The ongoing launch in the United States continues to go well and the recent launches in Europe and Japan are on track. FIGHT-207, evaluating pemigatinib in tumor agnostic FGFR malignancies, is now closed to recruitment. Based on findings from this study, Incyte has identified populations that may potentially benefit from treatment with pemigatinib and intends to initiate Phase 2 studies in glioblastoma and non-small cell lung cancer by early next year.

Retifanlimab: In July, Incyte announced that the FDA issued a complete response letter for the Biologics License Application (BLA) for retifanlimab as a treatment for squamous cell carcinoma of the anal canal (SCAC). Registration-directed trials of retifanlimab in MSI-high endometrial and Merkel cell carcinoma are ongoing. The Marketing Authorization Application (MAA) seeking approval of retifanlimab in SCAC remains under review with the European Medicines Agency (EMA).

CCA = cholangiocarcinoma; DLBCL = diffuse large B-cell lymphoma; SCAC = squamous cell anal carcinoma; FL = follicular lymphoma; MZL = marginal zone lymphoma; MCL = mantle cell lymphoma; CLL = chronic lymphocytic leukemia

Inflammation and Autoimmunity (IAI) - key highlights

Ruxolitinib cream: In June, 52-week safety and efficacy data from the two Phase 3 TRuE-AD studies evaluating ruxolitinib cream in mild-to-moderate atopic dermatitis were presented at the Revolutionizing

Atopic Dermatitis (RAD) virtual symposium. These data were the basis for an NDA seeking approval of ruxolitinib cream for the treatment of atopic dermatitis (AD); the PDUFA date has been extended to September 21, 2021.

A Phase 3 trial (TRuE-AD3) evaluating ruxolitinib cream in children (ages 2 to <12 years) with atopic dermatitis is ongoing.

In May, Incyte announced positive topline results from its pivotal Phase 3 TRuE-V program of ruxolitinib cream in adolescent and adult patients with vitiligo. Both TRuE-V1 and TRuE-V2 studies met the primary and key secondary endpoints, including patient reported outcomes. The overall efficacy and safety profile of ruxolitinib cream is consistent with previously reported Phase 2 data, and no new safety signals were observed. The long-term efficacy and safety portions of both studies will continue as planned. The regulatory submission seeking approval of ruxolitinib cream in vitiligo is expected later this year.

Parsaclisib: At EHA, Incyte presented Phase 2 data evaluating parsaclisib in autoimmune hemolytic anemia. The majority of patients achieved a response with parsaclisib over the initial 12-week treatment period. Treatment with parsaclisib was generally well tolerated. Based on these results, Incyte plans to initiate a Phase 3 trial by end of year.

Discovery and early development - key highlights

Incyte's portfolio of other earlier-stage clinical candidates is summarized below.

1 INCB01158 development in collaboration with Calithera

2 Discovery collaboration with Agenus

3 MCLA-145 development in collaboration with Merus

Partnered - key highlights

Baricitinib: In July, Incyte and Lilly announced that the FDA would not meet the PDUFA action date for the sNDA for baricitinib for the treatment of adults with moderate to severe atopic dermatitis. Baricitinib is also being studied in alopecia areata with an expected submission in H2 2021.

1 Worldwide rights to baricitinib licensed to Lilly: approved as Olumiant in multiple territories globally for certain patients with moderate-to-severe rheumatoid arthritis; approved as Olumiant in EU and Japan for certain patients with atopic dermatitis

2 Worldwide rights to capmatinib licensed to Novartis
