All information provided in this section is applicable to XELJANZ/XELJANZ XR/XELJANZ Oral Solution as they contain the same active ingredient (tofacitinib).
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to XELJANZ/XELJANZ XR/XELJANZ Oral Solution during pregnancy. Patients should be encouraged to enroll in the XELJANZ/XELJANZ XR/XELJANZ Oral Solution pregnancy registry if they become pregnant. To enroll or obtain information from the registry, patients can call the toll free number 1-877-311-8972.
Risk Summary
Available data with XELJANZ/XELJANZ XR/XELJANZ Oral Solution use in pregnant women are insufficient to establish a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with rheumatoid arthritis and UC in pregnancy (see Clinical Considerations). In animal reproduction studies, fetocidal and teratogenic effects were noted when pregnant rats and rabbits received tofacitinib during the period of organogenesis at exposures multiples of 73-times and 6.3-times the maximum recommended dose of 10 mg twice daily, respectively. Further, in a peri- and post-natal study in rats, tofacitinib resulted in reductions in live litter size, postnatal survival, and pup body weights at exposure multiples of approximately 73-times the recommended dose of 5 mg twice daily and approximately 36 times the maximum recommended dose of 10 mg twice daily, respectively (see Data).
The estimated background risks of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risks in the U.S. general population of major birth defects and miscarriages are 2 to 4% and 15 to 20% of clinically recognized pregnancies, respectively.
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 or ulcerative colitis. 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 a rat embryofetal developmental study, in which pregnant rats received tofacitinib during organogenesis, tofacitinib was teratogenic at exposure levels approximately 146 times the recommended dose of 5 mg twice daily, and approximately 73 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 100 mg/kg/day in rats). Teratogenic effects consisted of external and soft tissue malformations of anasarca and membranous ventricular septal defects, respectively; and skeletal malformations or variations (absent cervical arch; bent femur, fibula, humerus, radius, scapula, tibia, and ulna; sternoschisis; absent rib; misshapen femur; branched rib; fused rib; fused sternebra; and hemicentric thoracic centrum). In addition, there was an increase in post-implantation loss, consisting of early and late resorptions, resulting in a reduced number of viable fetuses. Mean fetal body weight was reduced. No developmental toxicity was observed in rats at exposure levels approximately 58 times the recommended dose of 5 mg twice daily, and approximately 29 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in pregnant rats).
In a rabbit embryofetal developmental study in which pregnant rabbits received tofacitinib during the period of organogenesis, tofacitinib was teratogenic at exposure levels approximately 13 times the recommended dose of 5 mg twice daily, and approximately 6.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in rabbits) in the absence of signs of maternal toxicity. Teratogenic effects included thoracogastroschisis, omphalocele, membranous ventricular septal defects, and cranial/skeletal malformations (microstomia, microphthalmia), mid-line and tail defects. In addition, there was an increase in post-implantation loss associated with late resorptions. No developmental toxicity was observed in rabbits at exposure levels approximately 3 times the recommended dose of 5 mg twice daily, and approximately 1.5 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 10 mg/kg/day in pregnant rabbits).
In a peri- and postnatal development study in pregnant rats that received tofacitinib from gestation day 6 through day 20 of lactation, there were reductions in live litter size, postnatal survival, and pup body weights at exposure levels approximately 73 times the recommended dose of 5 mg twice daily, and approximately 36 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 50 mg/kg/day in rats). There was no effect on behavioral and learning assessments, sexual maturation or the ability of the F1 generation rats to mate and produce viable F2 generation fetuses in rats at exposure levels approximately 17 times the recommended dose of 5 mg twice daily, and approximately 8.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 10 mg/kg/day in rats).
Risk Summary
There are no data on the presence of tofacitinib in human milk, the effects on a breastfed infant, or the effects on milk production. Tofacitinib is present in the milk of lactating rats (see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk. Given the serious adverse reactions seen in patients treated with XELJANZ/XELJANZ XR/XELJANZ Oral Solution, such as increased risk of serious infections, advise patients that breastfeeding is not recommended during treatment and for at least 18 hours after the last dose of XELJANZ/XELJANZ Oral Solution or 36 hours after the last dose of XELJANZ XR (approximately 6 elimination half-lives).
Contraception
Females
In an animal reproduction study, tofacitinib at AUC multiples of 13 times the recommended dose of 5 mg twice daily and 6.3 times the maximum recommended dose of 10 mg twice daily demonstrated adverse embryo-fetal findings [see Use in Specific Populations (8.1)]. However, there is uncertainty as to how these animal findings relate to females of reproductive potential treated with the recommended clinical dose. Consider pregnancy planning and prevention for females of reproductive potential.
Infertility
Females
Based on findings in rats, treatment with XELJANZ/XELJANZ XR/XELJANZ Oral Solution may result in reduced fertility in females of reproductive potential. It is not known if this effect is reversible [see Nonclinical Toxicology (13.1)].
The safety and effectiveness of XELJANZ/XELJANZ Oral Solution for the treatment of active pcJIA have been established in patients 2 years to 17 years of age. Use of XELJANZ/XELJANZ Oral Solution for the treatment of pediatric patients with active pcJIA in this age group is supported by evidence from adequate and well-controlled studies of XELJANZ in adult RA patients with additional data from a clinical trial of XELJANZ/XELJANZ Oral Solution in pediatric patients (2 years to 17 years of age) with active pcJIA consisting of an 18-week, open label, run-in period followed by a 26-week placebo-controlled, randomized withdrawal period [see Clinical Studies (14.5)]. The safety and effectiveness of XELJANZ/XELJANZ Oral Solution have not been established in pcJIA patients less than 2 years of age.
Adverse reactions observed in pediatric patients receiving XELJANZ/XELJANZ Oral Solution were consistent with those reported in RA patients [see Adverse Reactions (6.1)].
Safety and efficacy of XELJANZ/XELJANZ Oral Solution in pediatric patients for indications other than pcJIA have not been established.
The safety and effectiveness of XELJANZ XR in pediatric patients have not been established.
Of the 3315 patients who enrolled in rheumatoid arthritis Studies I to V, a total of 505 rheumatoid arthritis patients were 65 years of age and older, including 71 patients 75 years and older. The frequency of serious infection among XELJANZ-treated subjects 65 years of age and older was higher than among those under the age of 65.
Of the 1156 XELJANZ-treated patients in the UC program, a total of 77 patients (7%) were 65 years of age or older. The number of patients aged 65 years and older was not sufficient to determine whether they responded differently from younger patients.
As there is a higher incidence of infections in the elderly population in general, caution should be used when treating the elderly [see Warnings and Precautions (5.1)].
As there is a higher incidence of infection in diabetic population in general, caution should be used when treating patients with diabetes.
Moderate and Severe Impairment
XELJANZ-treated patients with moderate or severe renal impairment had greater tofacitinib blood concentrations than XELJANZ-treated patients with normal renal function. Therefore, dosage adjustment of XELJANZ/XELJANZ XR/XELJANZ Oral Solution is recommended in patients with moderate or severe renal impairment (including but not limited to those with severe insufficiency who are undergoing hemodialysis) [see Dosage and Administration (2.2, 2.3, 2.4)].
Severe Impairment
XELJANZ/XELJANZ XR/XELJANZ Oral Solution has not been studied in patients with severe hepatic impairment; therefore, use of XELJANZ/XELJANZ XR/XELJANZ Oral Solution in patients with severe hepatic impairment is not recommended.
Moderate Impairment
XELJANZ-treated patients with moderate hepatic impairment had greater tofacitinib blood concentration than XELJANZ-treated patients with normal hepatic function [see Clinical Pharmacology (12.3)]. Higher blood concentrations may increase the risk of some adverse reactions. Therefore, dosage adjustment of XELJANZ/XELJANZ XR/XELJANZ Oral Solution is recommended in patients with moderate hepatic impairment [see Dosage and Administration (2.2, 2.3, 2.4)].

Moderate and Severe Impairment
XELJANZ-treated patients with moderate or severe renal impairment had greater tofacitinib blood concentrations than XELJANZ-treated patients with normal renal function. Therefore, dosage adjustment of XELJANZ/XELJANZ XR/XELJANZ Oral Solution is recommended in patients with moderate or severe renal impairment (including but not limited to those with severe insufficiency who are undergoing hemodialysis) [see Dosage and Administration (2.2, 2.3, 2.4)].
Severe Impairment
XELJANZ/XELJANZ XR/XELJANZ Oral Solution has not been studied in patients with severe hepatic impairment; therefore, use of XELJANZ/XELJANZ XR/XELJANZ Oral Solution in patients with severe hepatic impairment is not recommended.
Moderate Impairment
XELJANZ-treated patients with moderate hepatic impairment had greater tofacitinib blood concentration than XELJANZ-treated patients with normal hepatic function [see Clinical Pharmacology (12.3)]. Higher blood concentrations may increase the risk of some adverse reactions. Therefore, dosage adjustment of XELJANZ/XELJANZ XR/XELJANZ Oral Solution is recommended in patients with moderate hepatic impairment [see Dosage and Administration (2.2, 2.3, 2.4)].
