Relapsed or refractory follicular lymphoma (FL) after two or more lines of systemic therapy,Relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy
12 mg/m2 IV over 5-15 minutes once daily on days 1-3 of a 28-day cycle, or as a single dose of 12-14 mg/m2 IV every 21 days. For acute nonlymphocytic leukemia, 12 mg/m2 IV daily for 3 days with cytarabine.
12 mg/kg intravenously on Day 1 of each 21-day cycle for 12 cycles in combination with bendamustine. For patients with relapsed or refractory follicular lymphoma after two or more prior therapies, the recommended dose is 12 mg/kg intravenously on Day 1 of each 28-day cycle until disease progression or unacceptable toxicity.
Terminal elimination half-life: 23-215 hours (mean ~37 hours). The long half-life reflects extensive tissue distribution and slow elimination, allowing weekly dosing.
Terminal half-life approximately 20 days (range 14-28 days), consistent with Ig G1 monoclonal antibody clearance via intracellular catabolism.
Mitoxantrone is extensively metabolized in the liver via oxidation and conjugation, primarily by cytochrome P450 enzymes, forming inactive metabolites. Elimination is mainly via the hepatobiliary system with fecal excretion; small amounts are excreted renally.
Metabolized via non-specific proteolysis into small peptides and amino acids; not metabolized by CYP450 enzymes.
Primarily hepatic (biliary/fecal) elimination: ~25% as unchanged drug and metabolites in feces over 5 days; renal excretion accounts for ~11% (6-11%) as unchanged drug. Less than 10% excreted unchanged in urine.
Primarily eliminated via biliary/fecal route; renal excretion is minimal (less than 1% of dose).
~78% bound to plasma proteins (primarily albumin).
No specific protein binding data; as a monoclonal antibody, it is not bound to plasma proteins in a significant manner.
Mean Vd: 8-22 L/kg (range 6-44 L/kg). Large Vd indicates extensive tissue distribution and binding to intracellular components.
Approximately 4.5 L (0.06 L/kg assuming 70 kg), indicating limited extravascular distribution, primarily confined to plasma and interstitial space.
Intravenous: 100% (only route of administration). Oral bioavailability is <5% and not clinically relevant; no other routes used.
Intravenous administration yields 100% bioavailability.
No dose adjustment required for GFR >50 m L/min. For GFR 10-50 m L/min: administer 75% of normal dose. For GFR <10 m L/min: administer 50% of normal dose.
No dose adjustment recommended for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not studied in severe renal impairment (Cr Cl <30 m L/min) or on dialysis.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 25%. Child-Pugh Class C: reduce dose by 50%.
No dose adjustment recommended for mild hepatic impairment (Child-Pugh A). Not studied in moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment.
Safety and efficacy not established; not recommended for pediatric use.
Safety and effectiveness in pediatric patients have not been established.
Monitor cardiac function closely due to increased risk of cardiotoxicity. Higher risk of myelosuppression; consider lower initial doses based on renal function (see renal adjustment).
No specific dose adjustment recommended for elderly patients (≥65 years). Clinical studies included patients up to 88 years; no overall differences in safety or efficacy observed.
1. Mitoxantrone should be administered under the supervision of a physician experienced in the use of cancer chemotherapy agents. 2. Cardiac toxicity, including congestive heart failure, can occur and may be cumulative; risk increases with prior anthracycline use, mediastinal radiotherapy, pre-existing cardiac disease, or concomitant cardiotoxic drugs. 3. Secondary acute myeloid leukemia (AML) has been reported in patients treated with mitoxantrone-containing regimens. 4. Severe myelosuppression will occur.

Mitoxantrone is teratogenic in animals and is classified as Pregnancy Category D. First trimester exposure is associated with increased risk of spontaneous abortion and major congenital malformations. Second and third trimester exposure may cause fetal growth restriction, myelosuppression, and cardiac toxicity. Use during pregnancy is contraindicated unless the potential benefit outweighs the risk.
COLUMVI (glofitamab) is a CD3/CD20 bispecific antibody. Based on its mechanism of action and animal studies, there is a potential for fetal harm. Ig G molecules cross the placenta; fetal exposure increases as pregnancy progresses, with the largest amount transferred during the third trimester. Glofitamab may cause fetal B-cell depletion and immune dysfunction. There are no adequate human data. Contraindicated during pregnancy; advise effective contraception during treatment and for 3 months after the last dose.
Mitoxantrone is excreted into human breast milk; the milk-to-plasma ratio is not well characterized. Due to the potential for serious adverse reactions in nursing infants, including immunosuppression and cardiotoxicity, breastfeeding is contraindicated during therapy and for at least 1 month after the last dose.
No data on presence in human milk, effects on the breastfed child, or milk production. Human Ig G is secreted into breast milk, but minimal systemic absorption in the infant is expected. Because of potential for serious adverse reactions (including B-cell depletion), advise patients not to breastfeed during treatment and for at least 3 months after the last dose. M/P ratio: unknown.
No specific dose adjustments are established for pregnancy. However, pharmacokinetics may be altered due to increased plasma volume and renal clearance. Dose adjustment based on body surface area and close monitoring for toxicity are recommended. Use lowest effective dose and consider alternative therapies if possible.
No clinical trials have evaluated dosing in pregnancy. Pharmacokinetics of therapeutic antibodies are not significantly altered by pregnancy-mediated changes; however, increased plasma volume and altered clearance may occur. No specific dose adjustments are recommended; if benefit outweighs risk, administer at standard dosing (2.5 mg and 10 mg step-up doses, then 30 mg fixed dose every 21 days for up to 12 cycles). Clinical judgment required due to lack of data; consider therapeutic drug monitoring if available.
Mitoxantrone is a topoisomerase II inhibitor and anthracenedione; cumulative lifetime dose should not exceed 140 mg/m² due to dose-dependent cardiotoxicity. Pre-treatment LVEF must be assessed and monitored regularly. Administration requires cardiac monitoring during infusion due to risk of arrhythmias.
COLUMVI (glofitamab) is a CD3x CD20 bispecific antibody for relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Administer with prior rituximab and premedication to mitigate cytokine release syndrome (CRS). Monitor for CRS closely during step-up dosing; consider tocilizumab for management. Ensure adequate IV hydration and uric acid monitoring for tumor lysis syndrome. Do not coadminister with other systemic immunosuppressants unless necessary. Assess for hepatitis B reactivation prior to initiation.
