Voclosporin

Moderate CYP3A4 inhibitors: Reduce LUPKYNIS daily dosage to 15.8 mg in the morning and 7.9 mg in the evening. ( 2.5 , 7.1 , 12.3 ) Strong and moderate CYP3A4 inducers: Avoid co-administration. ( 7.1 , 12.3 ) Certain P-gp substrates: Reduce dosage of certain P-gp substrates with a narrow therapeutic window when co-administered with LUPKYNIS. ( 7.2 , 12.3 )

7.1 Effect of Other Drugs on LUPKYNIS Strong and Moderate CYP3A4 Inhibitors Voclosporin is a sensitive CYP3A4 substrate. Co-administration with strong or moderate CYP3A4 inhibitors increases voclosporin exposure [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of LUPKYNIS adverse reactions. Co-administration of LUPKYNIS with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin) is contraindicated [see Contraindications ( 4 )] . Reduce LUPKYNIS dosage when co-administered with moderate CYP3A4 inhibitors (e.g., verapamil, fluconazole, diltiazem) [see Dosage and Administration ( 2.5 ] . Avoid food or drink containing grapefruit when taking LUPKYNIS.

Strong and Moderate CYP3A4 Inducers Voclosporin is a sensitive CYP3A4 substrate. Co-administration with strong or moderate CYP3A4 inducers decreases voclosporin exposure [see Clinical Pharmacology ( 12.3 )] , which may decrease the efficacy of LUPKYNIS. Avoid co-administration of LUPKYNIS with strong or moderate CYP3A4 inducers.

7.2 Effect of LUPKYNIS on Other Drugs Certain P-gp Substrates Voclosporin is a P-gp inhibitor. Co-administration of voclosporin increases exposure of P-gp substrates [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of adverse reactions of these substrates. For certain P-gp substrates with a narrow therapeutic window, reduce the dosage of the substrate as recommended in its prescribing information, if needed. OATP1B1 Substrates Voclosporin is an inhibitor of OATP1B1 and OATP1B3 transporters.

In one clinical study the concomitant administration of a single 40 mg dose of simvastatin with 23.7 mg BID voclosporin increased C max and AUC of the active metabolite simvastatin acid (an OATP1B1 substrate) by 3.1-fold and 1.8-fold, respectively [see Clinical Pharmacology ( 12.3 )] . Monitor for adverse reactions such as myopathy and rhabdomyolysis when OATP1B1/OATP1B3 substrates (e.g., simvastatin, atorvastatin, pravastatin, rosuvastatin, pitavastatin, fluvastatin) are used concomitantly with LUPKYNIS and reduce the dosage of these substrates as recommended in their prescribing information.

For example, when taking LUPKYNIS with simvastatin, limit the simvastatin dosage to 20 mg daily, or 40 mg daily for patients who have previously tolerated simvastatin 80 mg daily for at least one year without evidence of muscle toxicity.

8.1 Pregnancy 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…
