###  Risk Summary

Avoid use of LUPKYNIS in pregnant women due to the alcohol content of the drug formulation. The available data on the use of LUPKYNIS in pregnant patients are insufficient to determine whether there is a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with systemic lupus erythematosus (SLE) (see Clinical Considerations) .

LUPKYNIS may be used in combination with a background immunosuppressive therapy regimen that includes MMF. MMF used in pregnant women and men whose female partners are pregnant can cause fetal harm (major birth defects and miscarriage). Refer to the MMF prescribing information for more information on its use during pregnancy.

In animal reproductive studies, oral administration of either voclosporin or a 50:50 mixture of voclosporin and its cis-isomer was embryocidal and fetocidal in rats and rabbits at doses 15- and 1-times, respectively, the maximum recommended human dose (MRHD) of 23.7 mg twice a day, based on drug exposure AUC. There were no treatment-related fetal malformations or variations. Additional findings of reduced placental and fetal body weights occurred in rabbits at 0.1 to 0.3-times the MRHD and in rats at higher drug exposures. Voclosporin was transferred across the placenta in pregnant rats. For rats, but not all doses in rabbits, these effects were associated with maternal toxicity consisting of reductions in body weight gain. Dystocia was evident in a pre- and postnatal study in rats, but there were no effects of voclosporin on postnatal growth and development (see Data) .

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

###  Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk 

Pregnant women with SLE are at increased risk of adverse pregnancy outcomes, including worsening of the underlying disease, premature birth, miscarriage, and intrauterine growth restriction. Maternal LN increases the risk of hypertension and preeclampsia/eclampsia. Passage of maternal autoantibodies across the placenta may result in adverse neonatal outcomes, including neonatal lupus and congenital heart block.

Fetal/Neonatal adverse reactions

The formulation of LUPKYNIS contains alcohol (21.6 mg of dehydrated ethanol per capsule for a total daily dose of 129.4 mg/day). Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders and impaired intellectual development. There is no safe level of alcohol exposure in pregnancy; therefore, avoid use of LUPKYNIS in pregnant women.

###  Data

Animal Data

Voclosporin (90 to 95% trans-isomer) is the active ingredient in LUPKYNIS. Animal reproductive studies were primarily conducted with an approximate 50:50 mixture of voclosporin and its cis-isomer. Similarity of the toxicity effects of the 50:50 mixture and voclosporin was demonstrated in comparative toxicity studies with adult rats. Interconversion between cis and trans isomers was not detected with in vitro or in vivo studies.

In an embryofetal developmental study, pregnant rats were dosed orally, during the period of organogenesis from gestation days 6-17, with the 50:50 mixture of voclosporin and its cis-isomer, litter size was reduced due to increased fetal resorptions and deaths at drug exposures approximately 15-times the MRHD (on an AUC basis with a maternal oral dose of 25 mg/kg/day). Surviving fetuses had reduced placental weights and slightly reduced fetal weights. There were no treatment-related fetal malformations or variations with doses up to 15-times the MRHD, although reductions in ossification sites were observed in the metatarsal bones. This dose was associated with maternal toxicity based on decreased body weight gain. The no effect dose for both fetal and maternal effects occurred at a drug exposure approximately 7-times the MRHD (on an AUC basis with a maternal oral dose of 10 mg/kg/day).

Two embryofetal developmental studies were conducted in pregnant rabbits that received either the 50:50 mixture of voclosporin and its cis-isomer or voclosporin during the period of organogenesis from gestation days 6-18. Litter size was reduced due to increased fetal resorptions and deaths with 50:50 mixture at drug exposures approximately the MRHD (on an AUC basis with a maternal oral dose of 20 mg/kg/day). Increased resorptions were observed with voclosporin at 0.1-times the MRHD (on an AUC basis with a maternal dose of 20 mg/kg/day); however, litter size was not significantly affected. Decreased placental weights and fetal body weights were observed with the 50:50 mixture at doses 0.3-times the MRHD and higher (on an AUC basis with maternal oral doses of 10 mg/kg/day and higher). Decreased fetal body weights were observed with voclosporin at doses 0.1-times the MRHD and higher (on an AUC basis with maternal oral doses of 5 mg/kg/day and higher). There were no treatment-related malformations or variations. Both studies had reductions of ossification sites in the metacarpal bones with the 50:50 mixture at doses 2-times the MRHD, and the sternabrae and hyoid body and/or arches with voclosporin at doses 0.1-times the MRHD and higher. The high dose of 20 mg/kg/day 50:50 mixture of voclosporin was associated with maternal toxicity based on decreased body weight gains. These rabbit studies indicated that the toxicity of 50:50 mixture of voclosporin and its cis-isomer and voclosporin were qualitatively similar; however, voclosporin was more potent than the 50:50 mixture, consistent with its pharmacological potency. The no effect dose for the fetal effects of voclosporin occurred at a drug exposure approximately 0.01-times the MRHD (on an AUC basis with a maternal oral dose of 1 mg/kg/day).

In a pre-and post-natal developmental study, rats were dosed from gestation day 7 through lactation day 20 with a 50:50 mixture of voclosporin and its cis-isomer. Dystocia (delayed parturition) occurred at a dose 12-times the MRHD (on an AUC basis with a maternal oral dose of 25 mg/kg/day) that resulted in reductions of the mean number of total pups delivered and surviving pups per litter. This dose was associated with maternal toxicity based on decreased body weight gain. No adverse effects on dams or their pups were observed at doses 3-times the MRHD and lower (on an AUC basis with a maternal oral dose of 10 mg/kg/day). There were no effects on behavioral and physical development, or the reproductive performance of male or female pups. The no effect dose for delivery and pup survival was 10 mg/kg/day.
