SERIOUS INFECTIONS, MORTALITY, MALIGNANCY, MAJOR ADVERSE CARDIOVASCULAR EVENTS, and THROMBOSIS WARNING: SERIOUS INFECTIONS, MORTALITY, MALIGNANCY, MAJOR ADVERSE CARDIOVASCULAR EVENTS (MACE), and THROMBOSIS See full prescribing information for complete boxed warning. • Increased risk of serious bacterial, fungal, viral and opportunistic infections leading to hospitalization or death, including tuberculosis (TB). Discontinue treatment with CIBINQO if serious or opportunistic infection occurs. Test for latent TB before and during therapy; treat latent TB prior to use. Monitor all patients for active TB during treatment, even patients with initial negative latent TB test. ( 5.1 ) • Higher rate of all-cause mortality, including sudden cardiovascular death, with another JAK inhibitor vs. TNF blockers in rheumatoid arthritis (RA) patients. CIBINQO is not approved for use in RA patients. ( 5.2 ) • Malignancies have occurred with CIBINQO. Higher rate of lymphomas and lung cancers with another JAK inhibitor vs. TNF blockers in RA patients. ( 5.3 ) • MACE has occurred with CIBINQO. Higher rate of MACE (defined as cardiovascular death, myocardial infarction, and stroke) with another JAK inhibitor vs. TNF blockers in RA patients. ( 5.4 ) • Thrombosis has occurred with CIBINQO. Increased incidence of pulmonary embolism, venous and arterial thrombosis with another JAK inhibitor vs. TNF blockers. ( 5.5 ) Serious Infections Patients treated with CIBINQO may be at increased risk for developing serious infections that may lead to hospitalization or death. The most frequent serious infections reported with CIBINQO were herpes simplex, herpes zoster, and pneumonia [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ] . If a serious or opportunistic infection develops, discontinue CIBINQO and control the infection. Reported infections from Janus kinase (JAK) inhibitors used to treat inflammatory conditions: • Active tuberculosis, which may present with pulmonary or extrapulmonary disease. Test for latent TB before and during therapy; treat latent TB prior to use. Monitor all patients for active TB during treatment, even patients with initial negative latent TB test. • Invasive fungal infections, including cryptococcosis and pneumocystosis. Patients with invasive fungal infections may present with disseminated, rather than localized, disease. • Bacterial, viral, including herpes zoster, and other infections due to opportunistic pathogens. Avoid use of CIBINQO in pati

• Laboratory Abnormalities : Laboratory monitoring is recommended due to potential changes in platelets, lymphocytes, and lipids. ( 5.6 ) • Immunizations : Avoid use of live vaccines immediately prior to, during and immediately after CIBINQO treatment. ( 5.7 )

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 recommend

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.

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.

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.

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.

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.

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.
