CIBINQO

Limitations of Use

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

2.1 Recommended Testing, Evaluations, and Procedures Prior to Treatment Initiation

Perform the following tests and evaluations prior to CIBINQO initiation:

•

Tuberculosis (TB) infection evaluation – CIBINQO initiation is not recommended in patients with active TB. For patients with latent TB or those with a negative latent TB test who are at high risk for TB, start preventive therapy for latent TB prior to initiation of CIBINQO [see Warnings and Precautions (5.1)].

•

Viral hepatitis screening in accordance with clinical guidelines – CIBINQO initiation is not recommended in patients with active hepatitis B or hepatitis C [see Warnings and Precautions (5.1)].

•

A complete blood count (CBC) – CIBINQO initiation is not recommended in patients with a platelet count <150,000/mm3, an absolute lymphocyte count <500/mm3, an absolute neutrophil count <1,000/mm3, or a hemoglobin value <8 g/dL [see Warnings and Precautions (5.6)].

Complete any necessary immunizations, including herpes zoster vaccinations, in agreement with current immunization guidelines prior to CIBINQO initiation [see Warnings and Precautions (5.7)].

2.2 Recommended Dosage

The recommended dose is 100 mg once daily. If an adequate response is not achieved with CIBINQO 100 mg once daily, consider increasing the dosage to 200 mg once daily.

Discontinue CIBINQO if an adequate response is not achieved with 200 mg once daily.

Use the lowest efficacious dose to maintain response.

CIBINQO can be used with or without topical corticosteroids.

If a dose is missed, administer the dose as soon as possible unless it is less than 12 hours before the next dose, in which case skip the missed dose. Thereafter, resume dosing at the regular scheduled time.

2.3 Recommended Dosage in Patients with Renal Impairment or Hepatic Impairment

2.4 Recommended Dosage in CYP2C19 Poor Metabolizers

In patients who are known or suspected to be CYP2C19 poor metabolizers, the recommended dosage of CIBINQO is 50 mg once daily [see Use in Specific Populations (8.8) and Clinical Pharmacology (12.5)]. If an adequate response is not achieved with CIBINQO 50 mg once daily, consider increasing the dosage to 100 mg once daily. Discontinue therapy if inadequate response is seen after dosage increase to 100 mg once daily.

2.5 Dosage Modifications due to Strong Inhibitors

In patients taking strong inhibitors of cytochrome P450 (CYP) 2C19, reduce the dosage to 50 mg once daily [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)]. If an adequate response is not achieved with CIBINQO 50 mg daily, consider increasing the dosage to 100 mg once daily. Discontinue therapy if inadequate response is seen after dosage increase to 100 mg once daily.

2.6 Treatment Discontinuation due to Serious Infections or Hematologic Adverse Reactions

2.7 Administration Instructions

Administer CIBINQO with or without food at approximately the same time each day.

Swallow CIBINQO tablets whole with water. Do not crush, split, or chew CIBINQO tablets.

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.

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

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.

8.1 Pregnancy

8.2 Lactation

8.3 Females and Males of Reproductive Potential

8.4 Pediatric Use

The safety and effectiveness of CIBINQO in pediatric patients 12 years of age and older with atopic dermatitis have been established.

In trials Trial-AD-1 and Trial-AD-2, 124 pediatric subjects 12 to less than 18 years old weighing 25 kg or more with moderate-to-severe atopic dermatitis were enrolled and randomized to receive either CIBINQO 100 mg (N=51), 200 mg (N=48), or matching placebo (N=25) in monotherapy. Additional 284 pediatric subjects 12 to less than 18 years of age weighing 25 kg or more with moderate-to-severe atopic dermatitis, were enrolled and randomized to receive either CIBINQO 100 mg (N=95) or 200 mg (N=94) or matching placebo (N=95) in combination with topical corticosteroids in Trial-AD-4. Efficacy and adverse reaction profile were comparable between the pediatric patients and adults [see Clinical Studies (14) and Adverse Reactions (6.1)].

The safety and effectiveness of CIBINQO have not been established in pediatric patients below 12 years of age.

8.5 Geriatric Use

A total of 145 (4.6%) subjects 65 years of age and older, while 25 (0.8%) were 75 years of age and older, were enrolled in CIBINQO clinical trials. Clinical trials of CIBINQO did not include sufficient numbers of subjects 65 years of age and older to determine whether they respond differently from younger adult subjects.

A higher proportion of subjects 65 years of age and older discontinued from clinical trials compared to younger subjects. Among all subjects exposed to CIBINQO, including the long-term extension trial, confirmed ALC <500/mm3 occurred only in subjects 65 years of age and older. A higher proportion of subjects 65 years of age and older had platelet counts <75,000/mm3. The incidence rate of herpes zoster in subjects 65 years of age and older treated with CIBINQO (7.40 per 100 patient-years) was higher than that of subjects 18 to less than 65 years of age (3.44 per 100 patient-years).

8.6 Renal Impairment

In patients with severe (eGFR <30 mL/min) and moderate (eGFR 30–59 mL/min) renal impairment, the combined exposure (AUCinf,u) of abrocitinib and its two active metabolites, M1 and M2, is increased compared to patients with normal renal function (eGFR ≥90 mL/min) [see Clinical Pharmacology (12.3)]. This may increase the risk of adverse reactions such as infections.

CIBINQO is not recommended for use in patients with severe renal impairment and ESRD including those on renal replacement therapy [see Dosage and Administration (2.3)].

A dosage reduction in patients with moderate renal impairment is recommended. No dosage adjustment is required in patients with mild renal impairment (eGFR 60–89 mL/min) [see Dosage and Administration (2.3)].

CIBINQO has not been studied in subjects on renal replacement therapy. In Phase 3 clinical trials, CIBINQO was not evaluated in subjects with atopic dermatitis with baseline creatinine clearance values less than 40 mL/min.

8.7 Hepatic Impairment

Avoid use of CIBINQO in patients with severe (Child Pugh C) hepatic impairment. In clinical trials, CIBINQO was not evaluated in subjects with severe (Child Pugh C) hepatic impairment.

Dosage adjustment is not required in patients with mild (Child Pugh A) or moderate (Child Pugh B) hepatic impairment based on similar combined exposure (AUCinf,u) of abrocitinib and its two active metabolites, M1 and M2 compared to patients with normal hepatic function [see Clinical Pharmacology (12.3)].

8.8 CYP2C19 Poor Metabolizers

In patients who are CYP2C19 poor metabolizers, the AUC of abrocitinib is increased compared to CYP2C19 normal metabolizers due to reduced metabolic clearance. Dosage reduction of CIBINQO is recommended in patients who are known or suspected to be CYP2C19 poor metabolizers based on genotype or previous history/experience with other CYP2C19 substrates [see Dosage and Administration (2.4) and Clinical Pharmacology (12.5)].

12.1 Mechanism of Action

CIBINQO is a Janus kinase (JAK) inhibitor.

Abrocitinib reversibly inhibits JAK1 by blocking the adenosine triphosphate (ATP) binding site. In a cell-free isolated enzyme assay, abrocitinib was selective for JAK1 over JAK2 (28-fold), JAK3 (>340-fold), and tyrosine kinase (TYK) 2 (43-fold), as well as the broader kinome. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness is not currently known. Both the parent compound and the active metabolites inhibit JAK1 activity in vitro with similar levels of selectivity.

12.2 Pharmacodynamics

Treatment with CIBINQO was associated with dose-dependent reduction in serum markers of inflammation, including high sensitivity C-reactive protein (hsCRP), interleukin-31 (IL-31) and thymus and activation regulated chemokine (TARC). These changes returned to near baseline within 4 weeks of drug discontinuation.

12.3 Pharmacokinetics

Abrocitinib plasma Cmax and AUC increased dose proportionally up to 200 mg. Steady-state plasma concentrations of abrocitinib are achieved within 48 hours after once daily administration.

12.5 Pharmacogenomics

Patients who are CYP2C19 poor metabolizers have little to no CYP2C19 enzyme function compared to CYP2C19 normal metabolizers that have fully functional CYP2C19 enzymes.

After single doses of abrocitinib, CYP2C19 poor metabolizers demonstrated dose-normalized AUC of abrocitinib values that were 2.3-fold higher when compared to CYP2C19 normal metabolizers. Approximately 3–5% of Whites and Blacks and 15 to 20% of Asians are CYP2C19 poor metabolizers [see Dosage and Administration (2.4) and Use in Specific Populations (8.8)].

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.
