Relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease,Reduction of risk of hospitalization and all-cause mortality in COVID-19 (EUA, no longer authorized)
JOENJA (lenalidomide) 2.5 mg orally once daily on days 1-21 of a 28-day cycle.
0.5 mg orally once daily
Terminal elimination half-life is approximately 12-15 hours in patients with normal renal function. This supports once-daily dosing in most indications. Half-life is prolonged in renal impairment, requiring dose adjustment.
Terminal elimination half-life is approximately 6–9 days; due to extensive tissue distribution, steady-state is reached within 1–2 months of daily dosing.
Primarily metabolized by CYP3A4 and aldehyde oxidase (AO). Minor pathways include CYP3A5 and CYP2C8.
Primarily metabolized by cytochrome P450 4F2 (CYP4F2) via omega-hydroxylation; also undergoes hydrolysis by non-CYP enzymes. Minor contribution from CYP3A4.
Primarily renal excretion of unchanged drug (approximately 70-80% of the dose). A small fraction (5-10%) is eliminated via feces via biliary excretion. The remainder is metabolized and excreted as inactive metabolites.
Primarily hepatic metabolism (CYP4F2) with subsequent biliary/fecal elimination (81% of total clearance); renal excretion accounts for <2.5% of unchanged drug.
Approximately 90-95% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein. Binding is saturable at high concentrations and may be altered in disease states (e.g., hepatic impairment, hypoalbuminemia).
>99.7% bound to plasma proteins, primarily albumin and lipoproteins.
Volume of distribution is approximately 0.6-0.8 L/kg, indicating distribution into total body water. This suggests extensive extravascular distribution, with higher concentrations in well-perfused organs (liver, kidneys) and lower in adipose tissue.
Approximately 1700 L (17 ± 6 L/kg) indicating extensive distribution into tissues, including erythrocytes, brain, and adipose tissue.
Oral bioavailability is approximately 60-70%, with moderate interindividual variability. Food does not significantly affect absorption. No other relevant routes (e.g., topical) are available; bioavailability via IV is 100%.
Oral bioavailability is approximately 93% (range 80–100%).
For Cr Cl 30-60 m L/min: 2.5 mg orally once daily; for Cr Cl <30 m L/min (not on dialysis): 1.25 mg orally once daily; for ESRD on dialysis: 2.5 mg orally once daily, dose after dialysis.
No dose adjustment required for GFR ≥15 m L/min. Fingolimod has not been studied in ESRD (GFR <15 m L/min) or dialysis; use caution.

No specific dose adjustment; use caution due to increased risk of bradycardia, infections, and comorbidities.
None.
Increased risk of serious infections, including life-threatening opportunistic infections such as progressive multifocal leukoencephalopathy (PML), cryptococcal meningitis, and herpes virus infections. Baseline and periodic monitoring required.
Hypertension (including hypertensive crisis),Cardiac dysfunction (reduced LVEF),Arterial thromboembolic events,Hepatic impairment (including hepatotoxicity),Renal impairment (including proteinuria),Hemorrhage,Gastrointestinal perforation or fistula,QT prolongation,Reversible posterior leukoencephalopathy syndrome (RPLS),Thyroid dysfunction,Wound healing complications
Risk of bradyarrhythmia and atrioventricular block at treatment initiation; require ECG monitoring. Macular edema, especially in patients with uveitis or diabetes. Reduced pulmonary function; avoid in severe respiratory disease. Posterior reversible encephalopathy syndrome (PRES). Hepatic injury; monitor liver enzymes. Fetal harm; effective contraception required. Increased risk of infections; withhold during serious infection. Avoid live vaccines during and for 2 months after treatment.
None known
Hypersensitivity to fingolimod or any component. Recent (within 6 months) myocardial infarction, unstable angina, stroke, TIA, decompensated heart failure, or NYHA class III/IV heart failure. History of Mobitz type II 2nd-degree or 3rd-degree AV block or sick sinus syndrome unless pacemaker in place. Severe untreated sleep apnea. Baseline prolonged QTc interval (>500 msec) or concurrent Class Ia or Class III antiarrhythmic drugs.
Avoid grapefruit, grapefruit juice, and star fruit as they inhibit CYP3A4 and may increase lapatinib levels. Administer on an empty stomach; food, especially high-fat meals, can increase lapatinib AUC by 2-3 times and Cmax by 3-4 times, increasing toxicity risk.
Grapefruit and grapefruit juice increase fingolimod exposure by inhibiting CYP3A4 and CYP4F2; avoid concurrent consumption.
First trimester: Based on animal studies, there is evidence of teratogenicity including cardiovascular and neural tube defects. Human data are limited; however, the drug should be avoided in the first trimester unless benefits outweigh risks. Second/third trimester: May cause fetal growth restriction and oligohydramnios; use only if clearly needed.
First trimester: FDA Pregnancy Category C. Animal studies show embryolethality, fetal malformations (including persistent truncus arteriosus and ventricular septal defects) and increased resorptions. In humans, S1P receptor modulators are associated with a 2-fold increase in major congenital malformations when exposed in the first trimester. Second and third trimesters: Risk of fetal bradycardia, QT prolongation, and growth restriction due to maternal lymphopenia and immune modulation.
Unknown if excreted in human milk. The M/P ratio has not been determined. Due to potential for serious adverse reactions in nursing infants, breastfeeding is not recommended during treatment and for at least 1 month after last dose.
Unknown if excreted in human breast milk. M/P ratio not established. Due to potential for serious adverse reactions in breastfed infants (e.g., immunosuppression), advise against breastfeeding during therapy and for 2 months after last dose.
Due to increased plasma volume and renal clearance during pregnancy, higher doses may be required. Consider dose titration based on therapeutic drug monitoring and clinical response. No specific dose adjustment is established; individualize therapy.
No specific dose adjustments established for pregnancy; however, pharmacokinetic changes (increased volume of distribution, renal clearance) may reduce drug exposure. Fingolimod is contraindicated in pregnancy due to fetal risk; use only if benefit justifies risk. Discontinue at least 2 months before planned conception due to long half-life (6-9 days).
JOENJA (lapatinib) is a dual tyrosine kinase inhibitor of EGFR and HER2. Use with caution in patients with severe hepatic impairment (Child-Pugh C); reduce dose to 750 mg/day. Monitor for QT prolongation, especially in patients with hypokalemia or hypomagnesemia, or those on concurrent QT-prolonging drugs. Diarrhea is common (grades 1-2 in ~50%); premedicate with loperamide and ensure adequate hydration. Hepatotoxicity (ALT >5x ULN) occurs in ~2%; discontinue if severe. Avoid concurrent strong CYP3A4 inducers (e.g., rifampin) as they decrease lapatinib AUC by up to 70%.
First-dose monitoring required for 6 hours post-initial dose due to bradycardia risk; obtain baseline ECG, blood pressure, and heart rate. Avoid use in patients with recent MI, unstable angina, stroke, TIA, or certain arrhythmias. Vaccinate against varicella zoster virus (VZV) before initiation if no history of chickenpox or vaccination. Monitor for macular edema, especially in patients with diabetes or uveitis. Lymphopenia is expected; do not discontinue for low lymphocyte counts unless infection occurs.

"Fingolimod, a sphingosine 1-phosphate receptor modulator used for multiple sclerosis, can inhibit the metabolism of lorcaserin, a serotonin 2C receptor agonist for weight management. This occurs via fingolimod's moderate inhibition of CYP2D6, the primary enzyme responsible for lorcaserin's oxidative deamination. Increased lorcaserin exposure may heighten the risk of serotonin-related adverse effects, including nausea, headache, and potentially life-threatening serotonin syndrome."
"Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, impairs B-cell receptor signaling and reduces B-cell and T-cell function, leading to immunosuppression. Fingolimod, a sphingosine-1-phosphate receptor modulator, sequesters lymphocytes in lymph nodes, further decreasing peripheral lymphocyte counts. Coadministration may result in profound immunosuppression, increasing the risk of serious infections, including opportunistic infections and viral reactivation, as well as potential impairment of vaccine responses."
"Dexamethasone, a potent corticosteroid with profound immunosuppressive and anti-inflammatory effects, may potentiate the immunosuppressive actions of fingolimod, a sphingosine-1-phosphate receptor modulator used in multiple sclerosis. This additive immunosuppression increases the risk of opportunistic infections, including viral reactivation (e.g., herpes zoster) and serious bacterial infections. Clinical outcomes may range from prolonged infections to life-threatening sepsis, particularly in patients receiving high-dose or prolonged dexamethasone therapy."
