Postmarketing Reports
Immune system disorders: Drug hypersensitivity (eg, rash, urticaria, angioedema)
Warnings
Black Box Warnings
Serious infections
- May increase risk for developing serious infections which may lead to hospitalization or death
- Most patients with rheumatoid arthritis who developed these infections were taking concomitant immunosuppressants (eg, methotrexate, corticosteroids)
- If a serious infection develops, interrupt dosing until infection is controlled
-
Reported infections include:
- Active TB, which may present with pulmonary or extrapulmonary disease; do not administer to patients with active TB
- Except those with COVID-19, test for latent TB before initiating and during therapy; consider treating for latent infection before initiating
- Invasive fungal infections, including candidiasis and pneumocystosis; patients with invasive fungal infections may present with disseminated, rather than localized, disease
- Bacterial, viral, and other infections due to opportunistic pathogens
- Consider risks and benefits before initiating therapy in patients with chronic or recurrent infection
- Closely monitor for developing signs and symptoms of infection during and after treatment, including the possible development of TB in patients who tested negative for latent TB before initiating baricitinib
Mortality and cardiovascular risk
- Higher rate of all-cause mortality observed, including sudden cardiovascular (CV) death, with another JAK inhibitor when compared with TNF blockers in a large, randomized, postmarketing safety study in patients with rheumatoid arthritis aged ≥50 years with ≥1 CV factor
-
CV risk
- Also, higher rate of major adverse cardiovascular events (MACE), defined as cardiovascular death, myocardial infarction (MI), and stroke, observed when compared with TNF blockers
- Patients who are current or past smokers are at additional increased risk
- Discontinue in patients that have experienced MI or stroke
Malignancies
- Higher rate of lymphoma and other malignancies (excluding nonmelanoma skin cancer) observed in patients with RA arthritis treated with another JAK inhibitor, when compared with TNF blockers
- Patients who are current or past smokers are at additional increased risk
Thrombosis
- Thrombosis, including deep venous thrombosis (DVT) and pulmonary embolism (PE), observed at an increased incidence in patients treated with baricitinib compared with placebo
- Additionally, cases of arterial thrombosis reported; many of these adverse events were serious and some resulted in death
- Patients with symptoms of thrombosis should be promptly evaluated
- Higher rate of thrombosis observed in patients with RA (aged ≥50 yr) with ≥1 CV risk factor treated with another JAK compared with TNF blockers; avoid in patients at risk
- Discontinue in patients with symptoms of thrombosis
Contraindications
None
Cautions
Hypersensitivity reactions (eg, angioedema, urticaria, rash) observed, including serious reactions; if serious hypersensitivity reaction occurs, promptly discontinue therapy while evaluating potential causes
Malignancies were observed in clinical studies; non-melanoma skin cancers reported; periodic skin examination is recommended for patients who are at increased risk for skin cancer
Higher rate for all-cause mortality and for MACE (defined as CV death, myocardial infarction, and stroke) reported with another JAK inhibitor compared with TNF blockers in patients who have RA and ≥1 CV risk
Increased incidence of thrombosis, including DVT and PE, observed compared with placebo; avoid therapy in patients who may be at increased risk of thrombosis
Gastrointestinal perforation reported in clinical studies, although role of JAK inhibition in these events is unknown
May increase incidence of neutropenia, lymphopenia, anemia, or elevated LFTs or lipids; monitor laboratory values at baseline and periodically during treatment
Promptly investigate cause of liver enzyme elevation recommended to identify potential cases of drug-induced liver injury; interrupt therapy if increased ALT or AST observed and drug-induced liver injury is suspected, until this diagnosis is excluded
Infection risk
- In patients with COVID-19, monitor for signs and symptoms of new infections during and after treatment; there is limited information regarding use in patients with COVID-19 and concomitant active serious infections; risks and benefits of treatment in COVID-19 patients with other concurrent infections should be considered
- Serious and sometimes fatal infections may develop owing to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens reported; may cause reactivation of latent TB or viral infections
- Perform screening for viral hepatitis in accordance with clinical guidelines before starting therapy; unknown impact on chronic viral hepatitis reactivation
- Consider risks and benefits before initiating in patients with chronic or recurrent infection, history of serious or opportunistic infection, underlying conditions predisposing them to infection, or patients who have been exposed to tuberculosis or have resided or traveled in areas of endemic tuberculosis or mycoses
- Consider TB therapy for patients with a negative test for latent TB but who have risk factors for TB infection; consultation with a physician with expertise in TB recommended to aid in decision about whether initiating anti-TB therapy is appropriate
- If a new infection develops during treatment, promptly initiate diagnostic tests appropriate for an immunocompromised patient; if necessary, initiate appropriate antimicrobial therapy and closely monitor; interrupt baricitinib therapy if patient unresponsive to treatment
- If herpes zoster occurs, interrupt treatment until episode resolves
Drug interaction overview
- Avoid use of live vaccines; update immunizations in agreement with current immunization guidelines before initiating
- Coadministration with strong OAT3 inhibitors may increase baricitinib systemic exposure; dosage modification recommended
Pregnancy & Lactation
Pregnancy
Report pregnancies to Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979)
Based on findings from animal reproduction studies, therapy may cause fetal harm during pregnancy; available data from clinical trials and postmarketing reports of 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 mother and the fetus associated with rheumatoid arthritis in pregnancy; consider risks and benefits with chronic use during pregnancy
Published data suggest that increased disease activity is associated with 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
Based on animal studies, therapy may cause fetal harm when administered during pregnancy; consider pregnancy planning and prevention for females of reproductive potential
Animal studies
- In animal embryo-fetal development studies, oral baricitinib administration to pregnant rats and rabbits at exposures equal to and greater than ~20 and 84 times the maximum recommended human dose (MRHD), respectively, resulted in reduced fetal body weights, increased embryo lethality (rabbits only), and dose-related increases in skeletal malformations
Lactation
Unknown if distributed in human breast milk
Baricitinib is present in the milk of lactating rats
Owing to species-specific differences in lactation physiology, the clinical relevance of these data are not clear
Because of the potential for serious adverse reactions in nursing infants, advise women with rheumatoid arthritis not to breastfeed while taking baricitinib
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Janus kinases (JAKs) pathways inhibitor; JAK consists of a group of intracellular tyrosine kinases that transmit signals from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoieses 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; baricitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs
Absorption
Absolute bioavailability: 80%
Peak plasma time: 1 hr
Steady-state achieved: 2-3 days
Distribution
Protein bound: 50% to plasma proteins and 45% to serum proteins
Vd: 76 L
Substrate of the P-gp, BCRP, OAT3 and MATE2-K transporters, which play roles in drug distribution
Metabolism
~6% of the orally administered baricitinib dose is identified as metabolites (3 from urine and 1 from feces), with CYP3A4 identified as the main metabolizing enzyme
No metabolites of baricitinib were quantifiable in plasma
Elimination
Half-life: 12 hr
Total body clearance: 8.9 L/hr
Excretion: 75% (69% unchanged) urine; 20% (15% unchanged) feces
Administration
Oral Administration
May take with or without food
Unable to swallow whole tablet
-
Oral
- Disperse tablet(s) for required dose in container with ~10 mL (5 mL minimum) of room temperature water by gently swirling contents; take immediately
- Rinse container with an additional 5-10 mL of water and administer entire contents to patient
-
Gastrostomy feeding tube
- Disperse tablet(s) for required dose in container with ~15 mL (10 mL minimum) of room temperature water by gently swirling contents; ensure tablets are sufficiently dispersed to flow through syringe tip
- Withdraw entire contents from container into an appropriate syringe and immediately administer through gastric tube
- Rinse container with an additional 10-15 mL of water, withdraw entire content into syringe and administer to patient
-
Nasogastric or orogastric feeding tube
- Disperse tablet(s) for required dose in container with ~30 mL of room temperature water by gently swirling contents; ensure tablets are sufficiently dispersed to flow through syringe tip
- Withdraw entire contents from container into an appropriate syringe and immediately administer through nasogastric tube
- To avoid clogging small diameter tubes (<12 Fr), the syringe can be held horizontally and shaken during administration
- Rinse container with enough (minimum of 15 mL) room temperature water, withdraw contents into syringe, and administer through nasogastric tube
Storage
Tablets: Store at 20-25°C (68-77°F); excursions permitted to 15-30°C (59-86°F)
Dispersed tablets in water: Stable for up to 4 hr
Handling
- Intact tablet: Not hazardous
- Crushed tablets: Unknown if powder may constitute a reproductive hazard to preparer; use proper control measures (eg, ventilated enclosure) or personal protective equipment (ie, N95 respirator)
