Rx only

1 INDICATIONS AND USAGE

CIBINQO is indicated for the treatment of adults and pediatric patients 12 years of age and older with refractory, moderate-to-severe atopic dermatitis whose disease is not adequately controlled with other systemic drug products, including biologics, or when use of those therapies is inadvisable.

Limitations of Use

CIBINQO is not recommended for use in combination with other JAK inhibitors, biologic immunomodulators, or other immunosuppressants.

4 CONTRAINDICATIONS

CIBINQO is contraindicated in patients taking antiplatelet therapies, except for low-dose aspirin (≤81 mg daily), during the first 3 months of treatment [see Warnings and Precautions (5.6), Drug Interactions (7.2), and Clinical Pharmacology (12.2)].

5 WARNINGS AND PRECAUTIONS

5.1 Serious Infections

The most frequent serious infections reported in clinical studies with CIBINQO for atopic dermatitis were herpes simplex, herpes zoster, and pneumonia [see Adverse Reactions (6.1)]. Serious infections leading to hospitalization or death, including tuberculosis and bacterial, invasive fungal, viral, and other opportunistic infections, have occurred in patients receiving JAK inhibitors used to treat inflammatory conditions.

Avoid use of CIBINQO in patients with active, serious infection including localized infections.

Consider the risks and benefits of treatment prior to initiating CIBINQO in patients:

•

with chronic or recurrent infection

•

who have been exposed to tuberculosis

•

with a history of a serious or an opportunistic infection

•

who have resided or traveled in areas of endemic tuberculosis or endemic mycoses

•

with underlying conditions that may predispose them to infection

Closely monitor patients for the development of signs and symptoms of infection during and after treatment with CIBINQO. If a patient develops a serious or opportunistic infection, discontinue CIBINQO. Initiate complete diagnostic testing and appropriate antimicrobial therapy. The risks and benefits of treatment with CIBINQO should be carefully considered prior to reinitiating therapy with CIBINQO.

Tuberculosis

Evaluate and test patients for TB before starting CIBINQO therapy and consider yearly screening for patients in highly endemic areas for TB. CIBINQO is not recommended for use in patients with active TB. For patients with a new diagnosis of latent TB or prior untreated latent TB, or for patients with a negative test for latent TB but who are at high risk for TB infection, start preventive therapy for latent TB prior to initiation of CIBINQO. Monitor patients for the development of signs and symptoms of TB, including patients who were tested negative for latent TB infection prior to initiating therapy.

Viral Reactivation

Viral reactivation, including herpes virus reactivation (e.g., herpes zoster, herpes simplex), was reported in clinical trials with CIBINQO [see Adverse Reactions (6.1)]. If a patient develops herpes zoster, consider interrupting CIBINQO until the episode resolves.

Hepatitis B virus (HBV) reactivation has been reported in patients receiving JAK inhibitors. Perform viral hepatitis screening in accordance with clinical guidelines before starting therapy and monitor for reactivation during therapy with CIBINQO. CIBINQO is not recommended for use in patients with active hepatitis B or hepatitis C [see Clinical Pharmacology (12.3)]. Monitor patients with inactive HBV for expression of HBV DNA during therapy with CIBINQO. If HBV DNA is detected during therapy with CIBINQO, consult a liver specialist.

5.2 Mortality

In a large, randomized, postmarketing safety trial of another JAK inhibitor in rheumatoid arthritis (RA) patients 50 years of age and older with at least one cardiovascular risk factor, a higher rate of all-cause mortality, including sudden cardiovascular death, was observed in subjects treated with the JAK inhibitor compared with TNF blockers. CIBINQO is not approved for use in RA.

Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with CIBINQO.

5.3 Malignancy and Lymphoproliferative Disorders

Malignancies, including non-melanoma skin cancer (NMSC), were observed in clinical trials with CIBINQO for atopic dermatitis [see Adverse Reactions (6.1)].

Perform periodic skin examination for patients who are at increased risk for skin cancer. Exposure to sunlight and UV light should be limited by wearing protective clothing and using broad-spectrum sunscreen.

Malignancies, including lymphomas, have occurred in patients receiving JAK inhibitors used to treat inflammatory conditions. In a large, randomized, postmarketing safety trial of another JAK inhibitor in RA subjects, a higher rate of malignancies (excluding non-melanoma skin cancer (NMSC)) was observed in subjects treated with the JAK inhibitor compared to those treated with TNF blockers. CIBINQO is not approved for use in RA. A higher rate of lymphomas was observed in subjects treated with the JAK inhibitor compared to those treated with TNF blockers. A higher rate of lung cancers was observed in current or past smokers treated with the JAK inhibitor compared to those treated with TNF blockers. In this trial, current or past smokers had an additional increased risk of overall malignancies.

Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with CIBINQO, particularly in patients with a known malignancy (other than a successfully treated NMSC), patients who develop a malignancy when on treatment, and patients who are current or past smokers.

5.4 Major Adverse Cardiovascular Events

Major adverse cardiovascular events were reported in clinical trials of CIBINQO for atopic dermatitis [see Adverse Reactions (6.1)].

In a large, randomized, postmarketing safety trial of another JAK inhibitor in RA subjects 50 years of age and older with at least one cardiovascular risk factor, a higher rate of major adverse cardiovascular events (MACE) defined as cardiovascular death, non-fatal myocardial infarction (MI), and non-fatal stroke was observed with the JAK inhibitor compared to those treated with TNF blockers. CIBINQO is not approved for use in RA. Patients who are current or past smokers are at additional increased risk.

Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with CIBINQO, particularly in patients who are current or past smokers and patients with other cardiovascular risk factors. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur. Discontinue CIBINQO in patients that have experienced a myocardial infarction or stroke.

5.5 Thrombosis

Deep venous thrombosis (DVT) and pulmonary embolism (PE) were observed in subjects receiving CIBINQO in the clinical trials for atopic dermatitis [see Adverse Reactions (6.1)].

Thrombosis, including DVT, PE, and arterial thrombosis have been reported in patients receiving JAK inhibitors used to treat inflammatory conditions. Many of these adverse reactions were serious and some resulted in death.

In a large, randomized, postmarketing safety trial of another JAK inhibitor in RA subjects 50 years of age and older with at least one cardiovascular risk factor, higher rates of overall thrombosis, DVT, and PE were observed compared to those treated with TNF blockers. CIBINQO is not approved for use in RA.

Avoid CIBINQO in patients that may be at increased risk of thrombosis. If symptoms of thrombosis occur, discontinue CIBINQO and evaluate and treat patients appropriately.

5.6 Laboratory Abnormalities

Hematologic Abnormalities

Treatment with CIBINQO was associated with an increased incidence of thrombocytopenia and lymphopenia [see Adverse Reactions (6.1)]. Prior to CIBINQO initiation, perform a CBC [see Dosage and Administration (2.1)]. CBC evaluations are recommended at 4 weeks after initiation and 4 weeks after dose increase of CIBINQO. Discontinuation of CIBINQO therapy is required for certain laboratory abnormalities [see Dosage and Administration (2.6)].

Lipid Elevations

Dose-dependent increase in blood lipid parameters were reported in subjects treated with CIBINQO [see Adverse Reactions (6.1)]. Lipid parameters should be assessed approximately 4 weeks following initiation of CIBINQO therapy and thereafter patients should be managed according to clinical guidelines for hyperlipidemia. The effect of these lipid parameter elevations on cardiovascular morbidity and mortality has not been determined.

5.7 Immunizations

Prior to initiating CIBINQO, complete all age-appropriate vaccinations as recommended by current immunization guidelines, including prophylactic herpes zoster vaccinations. Avoid vaccination with live vaccines immediately prior to, during and immediately after CIBINQO therapy.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of CIBINQO was evaluated in four randomized, placebo-controlled clinical trials (2 monotherapy, 1 combination therapy with topical corticosteroid, and 1 dose-ranging) and one long-term extension trial in subjects with moderate to severe atopic dermatitis (AD). A total of 1623 subjects with moderate to severe atopic dermatitis were treated with CIBINQO in these clinical trials representing 1428 patient-years of exposure. There were 634 subjects with at least 1 year of exposure to CIBINQO.

In the placebo-controlled clinical trials, a total of 1198 subjects were exposed to CIBINQO with 608 subjects receiving CIBINQO 100 mg once daily and 590 subjects receiving CIBINQO 200 mg once daily for up to 16 weeks. The median age of subjects was 33.0 years, 124 subjects (8.1%) were 12 to less than 18 years old and 94 subjects (6.1%) were 65 years of age or older. The majority of subjects were White (68.7%) and male (53.9%).

Adverse reactions occurring at ≥1% in any of the treated groups and at a higher rate than in the placebo group are presented in Table 3. A total of 61 (5.1%) subjects treated with CIBINQO were discontinued from the trials due to adverse reactions. The safety profile of CIBINQO in the monotherapy and the combination trial(s) were similar.

Specific Adverse Reactions

Exposure adjusted incidence rates were adjusted by trial size for all the adverse reactions reported in this section.

Overall Infections

In the placebo-controlled trials, for up to 16 weeks, overall infections were reported in 90 subjects (126.8 per 100 patient-years) treated with placebo, 211 subjects (168.8 per 100 patient-years) treated with CIBINQO 100 mg and 204 subjects (159.5 per 100 patient-years) treated with CIBINQO 200 mg. In all 5 clinical trials, including the long-term extension trial, overall infections were reported in 427 subjects (91.8 per 100 patient-years) treated with CIBINQO 100 mg and 394 subjects (103.2 per 100 patient-years) treated with CIBINQO 200 mg.

Serious Infections

In the placebo-controlled trials, for up to 16 weeks, serious infections were reported in 2 subjects (2.6 per 100 patient-years) treated with placebo, 6 subjects (3.9 per 100 patient-years) treated with CIBINQO 100 mg, and 2 subjects (1.3 per 100 patient-years) treated with CIBINQO 200 mg. In all 5 clinical trials, including the long-term extension trial, serious infections were reported in 18 subjects (2.3 per 100 patient-years) treated with CIBINQO 100 mg and 16 subjects (2.3 per 100 patient-years) treated with CIBINQO 200 mg. The most commonly reported serious infections were herpes simplex, herpes zoster, and pneumonia.

Herpes Zoster

In the placebo-controlled trials, for up to 16 weeks, opportunistic infections were generally cases of multidermatomal cutaneous herpes zoster. Herpes zoster was reported in 0 subjects treated with placebo, 3 subjects (1.9 per 100 patient-years) treated with CIBINQO 100 mg and 8 subjects (5.1 per 100 patient-years) treated with CIBINQO 200 mg. In all 5 clinical trials, including the long-term extension trial, herpes zoster was reported in 16 subjects (2.0 per 100 patient-years) treated with CIBINQO 100 mg and 35 subjects (5.2 per 100 patient-years) treated with CIBINQO 200 mg.

Malignancy

In the placebo-controlled trials, for up to 16 weeks, no malignancy was reported in subjects treated with placebo or CIBINQO 100 mg and in 1 patient (0.65 per 100 patient-years) treated with CIBINQO 200 mg. In all 5 clinical trials, including the long-term extension trial, malignancy was reported in 4 subjects (0.5 per 100 patient-years) treated with CIBINQO 100 mg and 2 subjects (0.3 per 100 patient-years) treated with CIBINQO 200 mg.

Thrombosis

In all clinical trials, including the long-term extension trial, pulmonary embolism was reported in 3 subjects (0.4 per 100 patient-years), who were treated with CIBINQO 200 mg. Deep vein thrombosis was reported in 2 subjects (0.3 per 100 patient-years) who were treated with CIBINQO 200 mg. No thrombosis occurred in subjects treated with CIBINQO 100 mg.

Major Adverse Cardiovascular Events

In the placebo-controlled trials, for up to 16 weeks, major adverse cardiovascular event (MACE) was reported in 1 subject (0.6 per 100 patient- years) treated with CIBINQO 100 mg. In all 5 clinical trials, including the long-term extension trial, MACE was reported in 1 patient (0.1 per 100 patient-years) treated with CIBINQO 100 mg and 2 subjects (0.3 per 100 patient-years) treated with CIBINQO 200 mg.

Thrombocytopenia

In the placebo-controlled trials, for up to 16 weeks, treatment with CIBINQO was associated with a dose-related decrease in platelet count. Maximum effects on platelets were observed within 4 weeks, after which the platelet count returned towards baseline despite continued therapy. In all 5 clinical trials, including the long-term extension trial, 6 subjects (0.9 per 100 patient- years) treated with CIBINQO 200 mg had adverse reactions of thrombocytopenia; no subjects treated with CIBINQO 100 mg had an adverse reaction of thrombocytopenia.

Lymphopenia

In the placebo-controlled trials, for up to 16 weeks, confirmed ALC <500/mm3 occurred in 2 subjects (1.2 per 100 patient-years) treated with CIBINQO 200 mg and 0 subjects treated with CIBINQO 100 mg or placebo. Both cases occurred in the first 4 weeks of exposure.

Lipid Elevations

In the placebo-controlled trials, for up to 16 weeks, there was a dose-related percent increase in low-density lipoprotein cholesterol (LDL-c), total cholesterol, and high-density lipoprotein cholesterol (HDL-c) relative to placebo at Week 4 which remained elevated through the final visit in the treatment period. Adverse reactions related to hyperlipidemia occurred in 1 subject (0.6 per 100 patient-years) exposed to CIBINQO 100 mg, 3 subjects (2.0 per 100 patient-years) exposed to CIBINQO 200 mg.

Retinal Detachment

In the placebo-controlled trials, for up to 16 weeks, retinal detachment occurred in 1 subject (0.6 per 100 patient-years) treated with CIBINQO 100 mg. In all 5 clinical trials, including the long-term extension trial, retinal detachment occurred in 2 subjects (0.3 per 100 patient-years) treated with CIBINQO 100 mg.

Creatine Phosphokinase Elevations (CPK)

In the placebo-controlled trials, for up to 16 weeks, events of blood CPK increased were reported in 6 subjects (7.5 per 100 patient-years) treated with placebo, 11 subjects (6.9 per 100 patient-years) treated with 100 mg of CIBINQO and 19 subjects (12.3 per 100 patient-years) treated with 200 mg of CIBINQO. Most elevations were transient, there were no reported adverse reactions of rhabdomyolysis.

Pediatric Subjects (12 to less than 18 years of age)

The safety of CIBINQO was assessed in a trial of 284 subjects 12 to less than 18 years of age with moderate-to-severe atopic dermatitis (Trial-AD-4). The safety profile of CIBINQO in these subjects, assessed through the initial treatment period of 12 weeks and the long-term period (213 with at least 52 weeks of abrocitinib exposure), was comparable to the safety profile from trials in adults with atopic dermatitis.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

In a 2-year oral carcinogenicity study in rats, abrocitinib increased the incidence of benign thymomas in female rats at doses of 10 and 30 mg/kg/day (2.8 and 14 times the MRHD, respectively, based on AUC comparison). Abrocitinib was not carcinogenic in female rats at 3 mg/kg/day (0.6 times the MRHD based on AUC comparison) or male rats at doses up to 30 mg/kg/day (14 times the MRHD based on AUC comparison). Abrocitinib was not carcinogenic in Tg.rasH2 mice at oral doses up to 60 mg/kg/day in males and 75 mg/kg/day in females.

Abrocitinib was not mutagenic in the bacterial mutagenicity assay (Ames assay). Although abrocitinib was aneugenic in the in vitro TK6 micronucleus assay, abrocitinib was not aneugenic or clastogenic in an in vivo rat bone marrow micronucleus assay.

Abrocitinib did not impair male fertility at doses up to 70 mg/kg/day (26 times the MRHD based on AUC comparison) or female fertility at 10 mg/kg/day (2 times the MRHD based on AUC comparison). Abrocitinib impaired female fertility (reducing fertility index, corpora lutea, and implantation sites) at 70 mg/kg/day (29 times the MRHD based on AUC comparison). Impaired fertility in female rats reversed 1 month after cessation of abrocitinib administration.

14 CLINICAL STUDIES

The efficacy of CIBINQO as monotherapy and in combination with background topical corticosteroids was evaluated in 4 randomized, double-blind, placebo- controlled trials [Trial-AD-1 (NCT03349060), Trial-AD-2 (NCT03575871), Trial- AD-3 (NCT03720470), and Trial-AD-4 (NCT03796676)] in 1900 subjects (see Table 8). Trial-AD-1 and Trial-AD-2 enrolled adult and pediatric subjects 12 years of age and older. Trial-AD-3 enrolled only adults (≥18 years of age) and Trial-AD-4 enrolled only pediatric subjects 12 to less than 18 years of age. The trials enrolled subjects with moderate-to-severe atopic dermatitis as defined by Investigator’s Global Assessment (IGA) score ≥3, Eczema Area and Severity Index (EASI) score ≥16, body surface area (BSA) involvement ≥10%, and Peak Pruritus Numerical Rating Scale (PP-NRS) ≥4 at the baseline visit prior to randomization.

Baseline Characteristics

In Trial-AD-1, Trial-AD-2, and Trial-AD-3, 53% of subjects were male, 69% of subjects were white, 64% of subjects had a baseline IGA score of 3 (moderate AD), and 36% of subjects had a baseline IGA score of 4 (severe AD). The baseline mean EASI score was 30. The baseline mean age was 36 years old with 8% of subjects 12 to less than 18 years old and 92% of subjects 18 years of age or older. Subjects in these trials were those who had inadequate response to previous topical therapy or were subjects for whom topical treatments were medically inadvisable or who had received systemic therapies including dupilumab. In each of the trials, over 40% of subjects had prior exposure to systemic therapy. In Trial-AD-1 and Trial-AD-2, 6% of the subjects had received dupilumab, whereas prior use of dupilumab was not allowed in Trial- AD-3.

In Trial-AD-4, 49% of subjects were female, 56% of subjects were White, 33% of subjects were Asian and 6% of subjects were Black. The median age was 15 years and the proportion of subjects with severe atopic dermatitis (IGA of 4) was 38%.

Trial Designs and Endpoints

Trial-AD-1, Trial-AD-2, Trial-AD-3, and Trial-AD-4 assessed the co-primary endpoints of IGA and EASI-75 responses at Week 12. The designs of the trials are summarized in Table 8.

Clinical Response

Monotherapy Trials

The results of the CIBINQO monotherapy trials (Trial-AD-1 and Trial-AD-2) are presented in Table 9.

The proportion of subjects achieving PP-NRS4 at Week 2 (defined as an improvement of ≥4 points from baseline in PP-NRS) was higher in subjects treated with CIBINQO monotherapy 200 mg once daily (28% in Trial-AD-1 and 24% in Trial-AD-2) and 100 mg once daily (11% in both trials) compared to placebo (2% in both trials).

A higher proportion of subjects in the CIBINQO monotherapy 100 mg or 200 mg once daily arms compared to placebo achieved improvement in itching at Week 12.

Combination Therapy Trials

The results of CIBINQO in combination with background topical corticosteroids in subjects 18 years of age and older (Trial-AD-3) are presented in Table 10.

The proportions of subjects achieving PP-NRS4 at Week 2 was higher in subjects treated with CIBINQO 200 mg once daily (30%) and 100 mg once daily (14%) in combination with background medicated topical therapies compared to placebo (8%).

The results of CIBINQO in combination with background topical corticosteroids for pediatric subjects 12 to less than 18 years of age (Trial-AD-4) are presented in Table 11.

The proportion of pediatric subjects 12 to less than 18 years of age achieving PP-NRS4 at Week 2 in Trial-AD-4 was higher with CIBINQO 200 mg once daily (25%) and 100 mg once daily (13%) compared to placebo (8%).

A higher proportion of subjects in the CIBINQO 200 mg once daily arm compared to placebo achieved improvement in itching at Week 12.

Subgroup Analysis (Monotherapy Trials and the Combination Therapy Trial in Subjects 18 Years of Age and Older)

Examination of age, gender, race, weight, and previous systemic AD therapy treatment did not identify differences in response to CIBINQO 100 mg or 200 mg once daily among these subgroups in Trial-AD-1, Trial-AD-2, and Trial-AD-3.
