5 WARNINGS AND PRECAUTIONS Hypersensitivity : Serious reactions have been reported. Discontinue OLUMIANT if a serious hypersensitivity reaction occurs. ( 5.6 ) Gastrointestinal Perforations : Monitor patients who may be at increased risk and evaluate promptly new onset of abdominal symptoms. ( 5.7 ) Laboratory Abnormalities : Monitor for changes in lymphocytes, neutrophils, hemoglobin, liver enzymes, and lipids. ( 5.8 ) Vaccinations : Avoid use with live vaccines. ( 5.9 ) 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 with rheumatoid arthritis receiving OLUMIANT. The most common serious infections reported with OLUMIANT included pneumonia, herpes zoster, and urinary tract infection [see Adverse Reactions ( 6.1 )] . Among opportunistic infections, tuberculosis, multidermatomal herpes zoster, esophageal candidiasis, pneumocystosis, acute histoplasmosis, cryptococcosis, cytomegalovirus, and BK virus were reported with OLUMIANT. Some patients have presented with disseminated rather than localized disease, and were often taking concomitant immunosuppressants such as methotrexate or corticosteroids. Avoid use of OLUMIANT in patients with an active, serious infection, including localized infections. Consider the risks and benefits of treatment prior to initiating OLUMIANT 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; or with underlying conditions that may predispose them to infection. In patients with rheumatoid arthritis or alopecia areata, closely monitor for the development of signs and symptoms of infection during and after treatment with OLUMIANT. Interrupt OLUMIANT in patients with rheumatoid arthritis or alopecia areata, if the patient develops a serious infection, an opportunistic infection, or sepsis. A patient who develops a new infection during treatment with OLUMIANT should undergo prompt and complete diagnostic testing appropriate for an immunocompromised patient; appropriate antimicrobial therapy should be initiated, the patient should be closely monitored, and OLUMIANT should be interrupted if the patient is not responding to therapy. Do not resume OLUMIANT until the infection is controlled. In patients with COVID-19, monitor for signs and symptoms of new infections during and after treatment with OLUMIANT. There is limited information regarding the use of OLUMIANT in patients with COVID-19 and concomitant active serious infections. The risks and benefits of treatment with OLUMIANT in COVID-19 patients with other concurrent infections should be considered. Tuberculosis Evaluate patients for active infection prior to administration of OLUMIANT. OLUMIANT should not be given to patients with active TB. Test patients with rheumatoid arthritis or alopecia areata for latent tuberculosis. Patients with rheumatoid arthritis or alopecia areata and latent tuberculosis (TB) should be treated with standard antimycobacterial therapy before initiating OLUMIANT. Consider anti-TB therapy prior to initiation of OLUMIANT in patients with a history of latent or active TB in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent TB but who have risk factors for TB infection. Consultation with a physician with expertise in the treatment of TB is recommended to aid in the decision about whether initiating anti-TB therapy is appropriate for an individual patient. During OLUMIANT use, monitor patients for the development of signs and symptoms of TB, including patients who tested negative for latent TB infection prior to initiating therapy. Viral Reactivation Viral reactivation, including cases of herpes virus reactivation (e.g., herpes zoster), were reported in clinical studies wi…

7 DRUG INTERACTIONS In patients taking strong Organic Anion Transporter 3 (OAT3) inhibitors (e.g., probenecid) the recommended dosage should be reduced. ( 2.7 , 7.1 ) 7.1 Strong OAT3 Inhibitors Baricitinib exposure is increased when OLUMIANT is co-administered with strong OAT3 inhibitors (such as probenecid), hence the dosage of baricitinib should be reduced by half the recommended dose [see Dosage and Administration ( 2.2 , 2.3 ) and Clinical Pharmacology ( 12.3 )] . 7.2 Other JAK Inhibitors or Biologic DMARDs OLUMIANT has not been studied in combination with other JAK inhibitors or with biologic DMARDs [see Indications and Usage ( 1.1 , 1.2 )] .

8.1 Pregnancy Risk Summary Based on the findings from animal reproduction studies, OLUMIANT may cause fetal harm during pregnancy. Available data from clinical trials and postmarketing case reports with OLUMIANT exposure in pregnancy are insufficient to inform a drug-associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are no human data on chronic baricitinib exposure throughout pregnancy. There are risks to the mother and the fetus associated with rheumatoid arthritis in pregnancy (see Clinical Considerations) . Consider the risks and benefits with chronic use of OLUMIANT during pregnancy. In animal embryo-fetal development studies, oral baricitinib administration to pregnant rats and rabbits at exposures equal to and greater than approximately 11 and 46 times the maximum recommended human dose (MRHD) of 4 mg/day, respectively, resulted in reduced fetal body weights, increased embryolethality (rabbits only), and dose-related increases in skeletal malformations. No developmental toxicity was observed in pregnant rats and rabbits treated with oral baricitinib during organogenesis at approximately 2 and 7 times the exposure at the MRHD, respectively. In a pre- and post-natal development study in pregnant female rats, oral baricitinib administration at exposures approximately 24 times the MRHD resulted in reduction in pup viability (increased incidence of stillborn pups and early neonatal deaths), decreased fetal birth weight, reduced fetal body weight gain, decreased cytotoxic T cells on post-natal day (PND) 35 with evidence of recovery by PND 65, and developmental delays that might be attributable to decreased body weight gain. No developmental toxicity was observed at an exposure approximately 5 times the exposure at the MRHD (see Data) . The background risks of major birth defects and miscarriage for the indicated population(s) are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Report pregnancies to Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979). Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with rheumatoid arthritis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Data Animal Data In an embryofetal development study in pregnant rats, dosed orally during the period of organogenesis from gestation days 6 to 17, baricitinib was teratogenic (skeletal malformations that consisted of bent limb bones and rib anomalies) at exposures equal to or greater than approximately 11 times the MRHD (on an AUC basis at maternal oral doses of 10 mg/kg/day and higher). No developmental toxicity was observed in rats at an exposure approximately 2 times the MRHD (on an AUC basis at a maternal oral dose of 2 mg/kg/day). In an embryofetal development study in pregnant rabbits, dosed orally during the period of organogenesis from gestation days 7 to 20, embryolethality, decreased fetal body weights, and skeletal malformations (rib anomalies) were observed in the presence of maternal toxicity at an exposure approximately 46 times the MRHD (on an AUC basis at a maternal oral dose of 30 mg/kg/day). Embryolethality consisted of increased post-implantation loss that was due to elevated incidences of both early and late resorptions. No developmental toxicity was observed in rabbits at an exposure approximately 7 times the MRHD (on an AUC basis at a maternal oral dose of 10 mg/kg/day). In a pre- and post-natal development study in pregnant female rats dosed orally from gestation day 6 through lactat…

Adverse Reactions in Patients with Rheumatoid Arthritis The safety of OLUMIANT was evaluated in six randomized double-blind placebo-controlled studies (three Phase 2, three Phase 3) and a long-term extension study in patients with moderately to severely active RA. Patients were randomized to placebo (1070 patients), OLUMIANT 2 mg (479 patients), or baricitinib 4 mg (997 patients). Patients could be switched to baricitinib 4 mg from placebo or OLUMIANT 2 mg from as early as Week 12 depending on the study design. All patients initially randomized to placebo were switched to baricitinib 4 mg by Week 24. During the 16-week treatment period, adverse events leading to discontinuation of treatment were reported by 35 patients (11.4 per 100 patient-years) treated with placebo, 17 patients (12.1 per 100 patient-years) with OLUMIANT 2 mg, and 40 patients (13.4 per 100 patient-years) treated with baricitinib 4 mg. During 0 to 52-week exposure, adverse events leading to discontinuation of treatment were reported by 31 patients (9.2 per 100 patient-years) with OLUMIANT 2 mg, and 92 patients (10.2 per 100 patient-years) treated with baricitinib 4 mg. Overall Infections – During the 16-week treatment period, infections were reported by 253 patients (82.1 per 100 patient-years) treated with placebo, 139 patients (99.1 per 100 patient-years) treated with OLUMIANT 2 mg, and 298 patients (100.1 per 100 patient-years) treated with baricitinib 4 mg. During 0 to 52-week exposure, infections were reported by 200 patients (59.6 per 100 patients-years) treated with OLUMIANT 2 mg, and 500 patients (55.3 per 100 patient-years) treated with baricitinib 4 mg. In the 0 to 52-week exposure population, the most commonly reported infections with OLUMIANT were viral upper respiratory tract infection, upper respiratory tract infection, urinary tract infection, and bronchitis. Serious Infections – During the 16-week treatment period, serious infections were reported in 13 patients (4.2 per 100 patient-years) treated with placebo, 5 patients (3.6 per 100 patient-years) treated with OLUMIANT 2 mg, and 11 patients (3.7 per 100 patient-years) treated with baricitinib 4 mg. During 0 to 52-week exposure, serious infections were report…
