Miscellaneous immune disorders:

Indications for LUPKYNIS:

Treatment of active lupus nephritis in combination with a background immunosuppressive therapy regimen.

Limitations of Use:

Not recommended in combination with cyclophosphamide, as safety and efficacy have not been established.

Adult Dosage:

See full labeling. Swallow whole. Take on an empty stomach. Initially 23.7mg twice daily (approx. 12hrs apart) in combination with mycophenolate mofetil and corticosteroids. Adjust dose based on eGFR. If eGFR <60mL/min/1.73m2 and reduced by >20% and <30% from baseline, reduce dose by 7.9mg twice daily. Reassess within 2 weeks; if eGFR is still reduced by >20% from baseline, reduce the dose again by 7.9mg twice daily. Discontinue if eGFR <60mL/min/1.73m2 and reduced by ≥30% from baseline. Reassess within 2 weeks; consider re-initiating at a lower dose (7.9mg twice daily) only if eGFR has returned to ≥80% of baseline. For patients that had a decrease in dose due to eGFR, consider increasing the dose by 7.9mg twice daily for each eGFR measurement that is ≥80% of baseline; do not exceed the starting dose. All: if no therapeutic benefit by 24 weeks, consider treatment discontinuation. Severe renal impairment or mild/moderate hepatic impairment: 15.8mg twice daily. Concomitant moderate CYP3A4 inhibitors: reduce to 15.8mg in the AM and 7.9mg in the PM.

Children Dosage:

Not established.

LUPKYNIS Contraindications:

Concomitant strong CYP3A4 inhibitors (eg, ketoconazole, itraconazole, clarithromycin).

Boxed Warning:

Malignancies. Serious infections.

LUPKYNIS Warnings/Precautions:

Increased risk of lymphomas, other malignancies (eg, skin). Avoid or limit sun exposure, UV light; examine for skin changes. Increased risk of infections (eg, bacterial, viral, fungal, protozoal), opportunistic infections, including cytomegalovirus, herpes zoster; monitor. Obtain eGFR at baseline; monitor closely every 2 weeks for the 1st month, then every 4 weeks thereafter. Consider dose reduction or discontinuation with decreases in eGFR from baseline; if persistent, evaluate for chronic nephrotoxicity. Check BP at baseline; do not initiate if BP >165/105mmHg or with hypertensive emergency. Monitor BP every 2 weeks for the 1st month after initiation, then as clinically indicated. Treat new-onset or exacerbations of pre-existing hypertension. Consider discontinuation if increases in BP is not manageable with dose reduction or other appropriate intervention. Monitor for neurologic symptoms (eg, tremors, paresthesias, headache, mental status changes, others); consider dose reduction or discontinuation if neurotoxicity occurs. Monitor serum potassium periodically during treatment. Consider discontinuing if pure red cell aplasia is diagnosed. Severe hepatic impairment (Child-Pugh C): avoid. Renal impairment (eGFR ≤45mL/min/1.73m<sup2): not recommended. Elderly. Pregnancy: avoid. Nursing mothers: not recommended (during and for at least 7 days after the last dose).

LUPKYNIS Classification:

Immunosuppressant (calcineurin-inhibitor).

LUPKYNIS Interactions:

See Contraindications. Potentiated by strong or moderate CYP3A4 inhibitors. Concomitant moderate CYP3A4 inhibitors (eg, verapamil, fluconazole, diltiazem); reduce dose (see Adults). Antagonized by strong or moderate CYP3A4 inducers (eg, rifampin, efavirenz); avoid concomitant use. Avoid live attenuated vaccines (eg, intranasal flu, measles, mumps, rubella, others), grapefruit or grapefruit juice. Concomitant with inactivated vaccines may not be sufficiently immunogenic. Increased risk of nephrotoxicity with nephrotoxic drugs. Increased risk of torsade de pointes with drugs that prolong the QTc interval. Concomitant drugs associated with hyperkalemia (eg, potassium-sparing diuretics, ACE inhibitors, ARBs); monitor. Potentiates P-gp substrates (eg, digoxin); reduce dose of substrate if needed. May potentiate OATP1B1 substrates (eg, statins); monitor.

Adverse Reactions:

GFR decreased, hypertension, diarrhea, headache, anemia, cough, UTI, upper abdominal pain, dyspepsia, alopecia, renal impairment, abdominal pain, mouth ulceration, fatigue, tremor, acute kidney injury, decreased appetite; hyperkalemia, QTc prolongation, pure red cell aplasia.
