Boxed Warning
SERIOUS INFECTIONS Patients treated with RINVOQ /RINVOQ LQ are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions ( 5.1 ), Adverse Reactions ( 6.1 )]. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. If a serious infection develops, interrupt RINVOQ /RINVOQ LQ until the infection is controlled. Reported infections include: Active tuberculosis, which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent tuberculosis before RINVOQ /RINVOQ LQ use and during therapy. Treatment for latent infection should be considered prior to RINVOQ /RINVOQ LQ use. Invasive fungal infections, including cryptococcosis and pneumocystosis. Bacterial, viral, including herpes zoster, and other infections due to opportunistic pathogens. The risks and benefits of treatment with RINVOQ /RINVOQ LQ should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with RINVOQ /RINVOQ LQ , including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy [see Warnings and Precautions ( 5.1 )]. MORTALITY In a large, randomized, postmarketing safety study in rheumatoid arthritis (RA) patients 50 years of age and older with at least one cardiovascular risk factor comparing another Janus kinase (JAK) inhibitor to tumor necrosis factor (TNF) blockers, a higher rate of all-cause mortality, including sudden cardiovascular death, was observed with the JAK inhibitor [see Warnings and Precautions ( 5.2 )] . MALIGNANCIES Lymphoma and other malignancies have been observed in patients treated with RINVOQ . In RA patients treated with another JAK inhibitor, a higher rate of malignancies (e
Contraindications
RINVOQ/RINVOQ LQ is contraindicated in patients with known hypersensitivity to upadacitinib or any of its excipients [see Warnings and Precautions ( 5.6 )].

Mechanism of Action
Upadacitinib is a Janus kinase (JAK) inhibitor. JAKs are intracellular enzymes which transmit signals arising from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoiesis and immune cell function. Within the signaling pathway, JAKs phosphorylate and activate signal transducers and activators of transcription (STATs) which modulate intracellular activity including gene expression. Upadacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through their pairing (e.g., JAK1/JAK2, JAK1/JAK3, JAK1/TYK2, JAK2/JAK2, JAK2/TYK2). In a cell-free isolated enzyme assay, upadacitinib had greater inhibitory potency at JAK1 and JAK2 relative to JAK3 and TYK2. In human leukocyte cellular assays, upadacitinib inhibited cytokine-induced STAT phosphorylation mediated by JAK1 and JAK1/JAK3 more potently than JAK2/JAK2 mediated STAT phosphorylation. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness is not currently known.
