Nasıl çalışır
12.1 Mechanism of Action Ruxolitinib, a Janus kinase (JAK) inhibitor, inhibits JAK1 and JAK2 which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of STATs (signal transducers and activators of transcription) to cytokine receptors, activation and subsequent localization of STATs to the nucleus leading to modulation of gene expression. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness is not currently known.

5 WARNINGS AND PRECAUTIONS Serious Infections: Serious bacterial, mycobacterial, fungal and viral infections have occurred. Regularly monitor patients for infection and manage it promptly. ( 5.1 ) Non-melanoma Skin Cancers . Basal cell and squamous cell carcinoma have occurred. Perform periodic skin examinations during treatment and following treatment as appropriate. ( 5.3 ) Thrombosis. Thromboembolic events have occurred. ( 5.5 ) Cytopenias: Thrombocytopenia, anemia, neutropenia, lymphopenia, and leukopenia have occurred. Perform CBC monitoring as clinically indicated. ( 5.6 ) 5.1 Serious Infections Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving oral JAK inhibitors. Serious lower respiratory tract infections were reported in the clinical development program with topical ruxolitinib. Avoid use of OPZELURA in patients with an active, serious infection, including localized infections. Consider the risks and benefits of treatment prior to initiating OPZELURA in patients: with chronic or recurrent infection with a history of a serious or an opportunistic infection who have been exposed to tuberculosis who have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or 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 OPZELURA. Interrupt OPZELURA if a patient develops a serious infection, an opportunistic infection, or sepsis. Do not resume OPZELURA until the infection is controlled. Tuberculosis No cases of active tuberculosis (TB) were reported in clinical trials with OPZELURA. Cases of active TB were reported in clinical trials of oral JAK inhibitors used to treat inflammatory conditions. Consider evaluating patients for latent and active TB infection prior to administration of OPZELURA. During OPZELURA use, monitor patients for the development of signs and symptoms of TB. Viral Reactivation Viral reactivation, including cases of herpes virus reactivation (e.g., herpes zoster), were reported in clinical trials with JAK inhibitors used to treat inflammatory conditions including OPZELURA. If a patient develops herpes zoster, consider interrupting OPZELURA treatment until the episode resolves. Hepatitis B and C The impact of JAK inhibitors used to treat inflammatory conditions including OPZELURA on chronic viral hepatitis reactivation is unknown. Patients with a history of hepatitis B or C infection were excluded from clinical trials. Hepatitis B viral load (HBV-DNA titer) increases, with or without associated elevations in alanine aminotransferase and aspartate aminotransferase, have been reported in patients with chronic HBV infections taking oral ruxolitinib. OPZELURA initiation is not recommended in patients with active hepatitis B or hepatitis C. 5.2 Mortality In a large, randomized, postmarketing safety study of an oral 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 patients treated with the JAK inhibitor compared with TNF blockers. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with OPZELURA. 5.3 Malignancy and Lymphoproliferative Disorders Malignancies, including lymphomas, were observed in clinical trials of oral JAK inhibitors used to treat inflammatory conditions. Patients who are current or past smokers are at additional increased risk. Malignancies, including lymphomas, have occurred in patients receiving JAK inhibitors used to treat inflammatory conditions. In a large, randomized, postmarketing safety study of an oral JAK inhibitor in RA patients, a higher rate of malignancies (excluding non-melanoma skin cancer) was observed in patients treated with the JAK inhibitor compared to those treated with TNF blockers. A higher rate of lymphomas was observed in patients 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 study, 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 OPZELURA, particularly in patients with a known malignancy (other than successfully treated non-melanoma skin cancers), patients who develop a malignancy when on treatment, and patients who are current or past smokers. Non-melanoma Skin Cancers Non-melanoma skin cancers including basal cell and squamous cell carcinoma have occurred in patients treated with OPZELURA. Perform periodic skin examinations during OPZELURA treatment and following treatment as appropriate. Exposure to sunlight and UV light should be limited by wearing protective clothing and using broad-spectrum sunscreen. 5.4 Major Adverse Cardiovascular Events (MACE) In a large, randomized, postmarketing safety study of an oral JAK inhibitor in RA patients 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. 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 OPZELURA, 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 OPZELURA in patients that have experienced a myocardial infarction or stroke. 5.5 Thrombosis Thromboembolic events were observed in clinical trials with OPZELURA. Thrombosis, including deep vein thrombosis (DVT), pulmonary embolism (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 study of an oral JAK inhibitor in RA patients 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. Avoid OPZELURA in patients who may be at increased risk of thrombosis. If symptoms of thrombosis occur, discontinue OPZELURA and evaluate and treat patients appropriately. 5.6 Cytopenias Thrombocytopenia, anemia, neutropenia, lymphopenia, and leukopenia were reported in the clinical trials with OPZELURA. Consider the benefits and risks for individual patients who have a known history of these events prior to initiating therapy with OPZELURA. Perform CBC monitoring as clinically indicated. Discontinue OPZELURA if signs and/or symptoms associated with clinically significant decreases in laboratory values occur. 5.7 Lipid Elevations Treatment with oral ruxolitinib has been associated with increases in lipid parameters including total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides.

12.3 Pharmacokinetics In Trial INCB18424-103, the pharmacokinetics of ruxolitinib were evaluated in 20 adult subjects and 21 pediatric subjects 13 years of age and older with atopic dermatitis with a mean ± SD BSA involvement of 37.5 ± 16.1% (range 25% to 90%). Subjects applied approximately 1.5 mg/cm 2 of OPZELURA (dose range was approximately 1.2 grams to 37.6 grams per application) twice daily for 28 days. Absorption Plasma concentrations of ruxolitinib were quantifiable in all subjects. In adult subjects, the mean ± SD maximum plasma concentration (C max ) and area under the concentration time curve from 0 to 12 hours post dose (AUC 0–12 ) for ruxolitinib on Day 1 were 449 ± 883 nM and 3215 ± 6184 h*nM, respectively. There is no evidence of ruxolitinib accumulation after daily application of OPZELURA for 28 days in subjects with atopic dermatitis. Distribution Plasma protein binding is approximately 97%. Elimination The mean terminal half-life of ruxolitinib following topical application of OPZELURA was estimated in 9 subjects and is approximately 116 hours. Metabolism Ruxolitinib is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9 in vitro. Excretion Ruxolitinib and its metabolites are primarily excreted by urine (74%) and feces (22%). Less than 1% is excreted as unchanged drug. Specific Populations Pediatric Patients In Trial INCB18424-103, in subjects 13 to 17 years of age with atopic dermatitis, the mean ± SD C max and AUC 0–12 for ruxolitinib on Day 1 were 110 ± 255 nM and 801 ± 2019 h*nM, respectively. In Trial INCB18424-109, the pharmacokinetics of ruxolitinib was evaluated in 27 subjects 2 to 11 years of age with atopic dermatitis with a mean ± SD BSA involvement of 58.9 ± 20.6% (range 35% to 92%). The mean ± SD daily dose of the cream was 8.5 ± 6.3 g. Plasma concentrations of ruxolitinib were quantifiable in all subjects. The mean ± SD steady state plasma concentration (C ss ) and projected area under the concentration time curve from 0 to 12 hours post dose (AUC 0-12h ) for ruxolitinib were 84.1 ± 183 nM and 1009.2 ± 2196 h*nM, respectively in subjects 7 to less than 12 years of age (n=12) and 109 ± 122 nM and 1308 ± 1464 h*nM, respectively in subjects 2 to less than 7 years of age (n=15). There is no evidence of ruxolitinib accumulation after twice daily application of OPZELURA for 28 days in subjects 2 years to 17 years of age with atopic dermatitis. Drug Interactions Clinical Studies Drug interaction studies with OPZELURA have not been conducted. Strong CYP3A4 inhibitors : The C max and AUC of ruxolitinib increased 33% and 91%, respectively, with administration of 10 mg single dose orally following ketoconazole 200 mg twice daily for four days, compared to receiving the oral ruxolitinib dose alone in healthy subjects. Mild or moderate CYP3A4 inhibitors : There was an 8% and 27% increase in the C max and AUC of ruxolitinib, respectively, with the administration of 10 mg single dose orally following erythromycin, a moderate CYP3A4 inhibitor, at 500 mg twice daily for 4 days, compared to receiving the oral ruxolitinib dose alone in healthy subjects. There are no clinical studies conducted with mild CYP3A4 inhibitor. CYP3A4 inducers: The C max and AUC of ruxolitinib decreased 32% and 61%, respectively, with the oral administration of 50 mg single dose of ruxolitinib following rifampin 600 mg once daily for 10 days, compared to receiving the oral ruxolitinib dose alone in healthy subjects. In Vitro Studies Cytochrome P450 (CYP) Enzymes: Ruxolitinib is not expected to inhibit CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and CYP3A4 or induce CYP1A2, 2B6 and 3A4 following topical application. Transporter Systems: Ruxolitinib is not expected to inhibit P-gp, BCRP, OATP1B1, OATP1B3, OCT1, OCT2, OAT1, or OAT3 transporter systems following topical application. Ruxolitinib is not a substrate for the P-gp transporter.
