• 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/mm 3 , an absolute lymphocyte count <500/mm 3 , an absolute neutrophil count <1,000/mm 3 , or a hemoglobin value <8 g/dL [see Warnings and Precautions (5.7) ] . Complete any necessary immunizations, including herpes zoster vaccinations, in agreement with current immunization guidelines prior to CIBINQO initiation [see Warnings and Precautions (5.8) ] . 2.2 Recommended Dosage The recommended dosage 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 dosage 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 Renal Impairment CIBINQO dosage recommendations for patients with renal impairment are provided in Table 1 [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] . In patients with mild and moderate renal impairment, if an adequate response is not achieved with initial dose, the dose of CIBINQO can be doubled. Table 1. Recommended Dosage in Patients with Renal Impairment Renal Impairment Stage Estimated Glomerular Filtration (eGFR) Glomerular filtration rate was estimated by the Modification of Diet in Renal Disease (MDRD) formula. Recommended Dosage Mild 60 – 89 mL/minute CIBINQO 100 mg once daily Moderate 30 – 59 mL/minute CIBINQO 50 mg once daily Severe Severe Renal Impairment and End-Stage Renal Disease include patients on renal replacement therapy. 15 – 29 mL/minute Not recommended for use End-Stage Renal Disease (ESRD) <15 mL/minute Hepatic Impairment CIBINQO is not recommended for use in patients with severe hepatic impairment (Child-Pugh C). The recommended dosage in patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment is the same as patients with normal hepatic function [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3) ]. 2.4 Recommended Dosage in CYP2C19 Poor Metabolizers In patients who are 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 for Strong CYP2C19 Inhibitors In patients who concomitantly use strong inhibitors of cytochrome P450 (CYP) 2C19, reduce the dosage of CIBINQO 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. Dosage modification is not required in patients taking moderate inhibitors of CYP2C19. 2.6 Treatment Discontinuation due to Serious Infections or Hematologic Adverse Reactions Serious or Opportunistic Infections If a patient develops a serious or opportunistic infection, discontinue CIBINQO and control the infection. The risks and benefits of treatment with CIBINQO should be carefully considered prior to reinitiating therapy with CIBINQO [see Warnings and Precautions (5.1) ] . Hematologic Abnormalities Recommendations for CIBINQO discontinuation for hematologic abnormalities are summarized in Table 2. Table 2.

Antiplatelet therapies except for low-dose aspirin (≤81 mg daily), during the first 3 months of treatment. ( 4 )

Warnings and precautions

• Hypoglycemia in Patients with Diabetes : Consider increased monitoring of blood glucose; advise diabetic patients to notify their healthcare provider if they develop signs and symptoms of hypoglycemia. ( 5.6 )
• Laboratory Abnormalities : Laboratory monitoring is recommended due to potential changes in platelets, lymphocytes, and lipids. ( 5.7 )
• Immunizations : Avoid use of live vaccines immediately prior to, during and immediately after CIBINQO treatment. ( 5.8 ) 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 patients with 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.

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) [see Clinical Studies (14) ] 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. Table 3.

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.

Drug interactions

• Strong Inhibitors of CYP2C19 : The recommended dosage is 50 mg once daily or 100 mg once daily for those patients who are not responding to 50 mg once daily. ( 2.5 , 7.1 )
• Moderate to Strong Inhibitors of Both CYP2C19 and CYP2C9, or Strong or Moderate CYP2C19 or CYP2C9 Inducers : Avoid concomitant use. ( 7.1 )
• Certain P-gp Substrates or Certain CYP2C19 Substrates : Monitor or titrate dosage of P-gp substrates or CYP2C19 substrates where small concentration changes may lead to serious or life-threatening toxicities. ( 7.2 ) 7.1 Effects of Other Drugs on CIBINQO Table 4 includes drugs with clinically significant drug interactions affecting CIBINQO. Table 4. Clinically Significant Drug Interactions Affecting CIBINQO Strong CYP2C19 Inhibitors Clinical Impact Concomitant use of CIBINQO with strong CYP2C19 inhibitors increases the combined exposure of abrocitinib and its two active metabolites, M1 and M2 which may increase the adverse reactions of CIBINQO [see Clinical Pharmacology (12.3) ]. Intervention Dosage reduction of CIBINQO is recommended when concomitantly used with strong CYP2C19 inhibitors [see Dosage and Administration (2.5) ]. Strong or Moderate Inhibitors of both CYP2C19 and CYP2C9 Clinical Impact Concomitant use of CIBINQO with drugs that are strong or moderate inhibitors of both CYP2C19 and CYP2C9 increases the exposure of abrocitinib and its two active metabolites, M1 and M2 which may increase the adverse reactions of CIBINQO [ Clinical Pharmacology (12.3) ]. Intervention Avoid concomitant use of CIBINQO with drugs that are moderate to strong inhibitors of both CYP2C19 and CYP2C9 . Strong or Moderate CYP2C19 or CYP2C9 Inducers Clinical Impact Concomitant use of CIBINQO with strong or moderate CYP2C19 or CYP2C9 inducers decreases the combined exposure of abrocitinib and its two active metabolites, M1 and M2, which may result in loss of or reduced clinical response [see Clinical Pharmacology (12.3) ] . Intervention Avoid concomitant use of CIBINQO with strong or moderate CYP2C19 or CYP2C9 inducers. 7.2 Effects of CIBINQO on Other Drugs Table 5 includes clinically significant drug interactions in which CIBINQO affects other drugs. Table 5. Clinically Significant Drug Interactions Affecting Other Drugs Certain P-gp Substrates Clinical Impact Concomitant use of CIBINQO with P-gp substrates increases plasma concentrations of P-gp substrates and may result in potential adverse reactions of the P-gp substrate where minimal increases in the concentration of the P-gp substrate may lead to serious adverse reactions [see Clinical Pharmacology (12.3) ] . Intervention Monitor appropriately or modify the dosage of the P-gp substrate where small concentration changes may lead to serious or life-threatening toxicities when concomitantly used with CIBINQO. Refer to the Prescribing Information of the P-gp substrate. Certain CYP2C19 Substrates Clinical Impact CIBINQO is a moderate inhibitor of CYP2C19. Concomitant use of CIBINQO with drugs that are primarily metabolized by the CYP2C19 enzyme may increase the plasma concentrations of the CYP2C19 substrate and may result in potential adverse reactions of the CYP2C19 substrate where minimal increases in the concentration of the CYP2C19 substrate may lead to serious adverse reactions [see Clinical Pharmacology (12.3) ] . Intervention Caution should be exercised when CIBINQO is concomitantly used with drugs that are CYP2C19 sensitive substrates where small concentration changes may lead to serious or life-threatening toxicities. Antiplatelet Therapy Drugs Clinical Impact Concomitant use of CIBINQO with antiplatelet therapy drugs may increase the risk of bleeding with thrombocytopenia [see Warnings and Precautions (5.5) and Clinical Pharmacology (12.2) ]. Intervention CIBINQO is contraindicated in patients taking antiplatelet drugs, except for low-dose aspirin (≤81 mg daily), during the first 3 months of treatment [see Contraindications (4) ] .

Use in specific populations

• Lactation : Breastfeeding not recommended. ( 8.2 )
• Renal Impairment : Not recommended in patients with severe renal impairment or end-stage renal disease. ( 8.6 )
• Hepatic Impairment : Not recommended in patients with severe hepatic impairment. ( 8.7 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to CIBINQO during pregnancy. Pregnant women exposed to CIBINQO and health care providers are encouraged to call 1-877-311-3770. Risk Summary Available data from pregnancies reported in clinical trials with CIBINQO are not sufficient to establish a drug‑associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of abrocitinib to pregnant rats and rabbits during organogenesis at exposure 11 or 4 times the maximum recommended human dose (MRHD) based on AUC comparison, respectively, resulted in maternal dystocia and skeletal variations in rats and no adverse effects in rabbits ( see Data ). The background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies carry some risk of birth defects, loss, or other adverse outcomes. The background risks in the U.S. general population of major birth defects and miscarriages are 2–4% and 15–20% of clinically recognized pregnancies, respectively. Data Animal Data In an embryofetal development study, abrocitinib was administered orally to pregnant rats at doses of 10, 30, or 60 mg/kg/day during the period of organogenesis. No fetal malformations were observed. Abrocitinib increased the incidence of skeletal variations of short 13 th ribs at 30 mg/kg/day (11 times the MRHD based on AUC comparison). Increased embryofetal lethality and additional skeletal variations (cervical arches with reduced ventral processes, thickened ribs, and unossified metatarsals) were noted at 60 mg/kg/day (17 times the MRHD based on AUC comparison). In an embryofetal development study, abrocitinib was administered orally to pregnant rabbits at doses of 10, 30, or 75 mg/kg/day during the period of organogenesis. No abrocitinib-related maternal or developmental toxicity was noted at doses up to 75 mg/kg/day (4 times the MRHD based on AUC comparison). In a prenatal and postnatal development study, abrocitinib was administered orally to pregnant rats at doses of 10, 30, and 60 mg/kg/day beginning on gestation day 6 and continuing through lactation day 20. Dystocia with prolonged parturition and reduced offspring body weights were noted at 30 mg/kg/day (11 times the MRHD based on AUC comparison). Postnatal survival was markedly decreased at 60 mg/kg/day (17 times the MRHD based on AUC comparison). No maternal toxicity was observed at 10 mg/kg/day (2.4 times the MRHD based on AUC comparison). No abrocitinib-related effects on postnatal developmental, neurobehavioral, or reproductive performance of offspring was noted at doses up to 30 mg/kg/day (11 times the MRHD based on AUC comparison). 8.2 Lactation Risk Summary There are no data on the presence of abrocitinib in human milk, the effects on the breast-fed infant, or the effects on milk production. Abrocitinib was secreted in milk of lactating rats ( see Data ) . When a drug is present in animal milk, it is likely that the drug will be present in human milk. Because of the serious adverse findings in adults, including risks of serious infections, malignancy, and thrombosis, advise women not to breastfeed during treatment with CIBINQO and for one day after the last dose (approximately 5–6 elimination half-lives). Data Animal Data Lactating female rats were orally administered a single dose of 10 mg/kg abrocitinib on lactation day 12. Abrocitinib AUC was approximately 5 times greater in milk than in plasma. 8.3 Females and Males of Reproductive Potential Infertility Females Based on the findings in rats, oral administration of CIBINQO may impair female fertility. Impaired fertility in female rats was reversible 1 month after cessation of abrocitinib oral administration [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of CIBINQO have been established in 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. 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) once daily 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) once daily 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. Juvenile Animal Toxicity Data In a juvenile animal toxicity study, abrocitinib was administered orally to juvenile rats at doses of 5, 25, and 75 mg/kg/day from postnatal day 10 (approximately equivalent to a human infant) through postnatal day 63 (approximately equivalent to an adolescent). Abrocitinib caused a reversible, dose‑related decrease in the primary spongiosa in the metaphysis of the proximal tibia and distal femur and adverse effects on bone development at all dose levels.

Postnatal survival was markedly decreased at 60 mg/kg/day (17 times the MRHD based on AUC comparison). No maternal toxicity was observed at 10 mg/kg/day (2.4 times the MRHD based on AUC comparison). No abrocitinib-related effects on postnatal developmental, neurobehavioral, or reproductive performance of offspring was noted at doses up to 30 mg/kg/day (11 times the MRHD based on AUC comparison).

Pediatric use

8.4 Pediatric Use The safety and effectiveness of CIBINQO have been established in 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. 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) once daily 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) once daily 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. Juvenile Animal Toxicity Data In a juvenile animal toxicity study, abrocitinib was administered orally to juvenile rats at doses of 5, 25, and 75 mg/kg/day from postnatal day 10 (approximately equivalent to a human infant) through postnatal day 63 (approximately equivalent to an adolescent). Abrocitinib caused a reversible, dose‑related decrease in the primary spongiosa in the metaphysis of the proximal tibia and distal femur and adverse effects on bone development at all dose levels. Abrocitinib caused irreversible dose-related small or misshapen femoral heads at doses ≥5 mg/kg/day (0.8 times the MRHD based on AUC comparison); irreversibly decreased femur size and caused paw malrotation and limb impairment at doses ≥25 mg/kg/day (7.2 times the MRHD based on AUC comparison); and fractures at 75 mg/kg/day (27 times the MRHD based on AUC comparison). In a follow-up study, abrocitinib (25 mg/kg/day, at least 4.5 times the MRHD based on AUC comparison) was orally administered to juvenile rats from postnatal day (PND) 10, 15, 21, or 30 through PND day 63. Administration beginning PND 10 caused adverse macroscopic and microscopic bone findings consistent with the previous juvenile animal study. However, administration beginning PND 15 (approximately equivalent to a 6- to 12-month old infant) caused non-adverse reversible microscopic bone findings. No bone findings were noted when administration began on PND 21 or 30 (approximately equivalent to 2- and 6-year old children, respectively).

Geriatric use

8.5 Geriatric Use A total of 145 (4.6%) subjects 65 years of age and older, of which 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/mm 3 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/mm 3 . 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).

Overdosage

There is no experience regarding human overdosage with CIBINQO. There is no specific antidote for overdose with CIBINQO. In case of an overdose, call Poison Control Center at 1-800-222-1222 for latest recommendations.

Abrocitinib has a molecular weight of 323.42 g/mol and a molecular formula of C 14 H 21 N 5 O 2 S. The structural formula of abrocitinib is: Each film-coated tablet contains 50 mg or 100 mg or 200 mg of abrocitinib and the following inactive ingredients: dibasic calcium phosphate anhydrous, hypromellose, iron oxide red, lactose monohydrate, Macrogol, magnesium stearate, microcrystalline cellulose, sodium starch glycolate, titanium dioxide, and triacetin. Chemical Structure

Mechanism of action

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.
