Enter a dose to see draw volume, final concentration, and rates.
Recommended Dosage The recommended dose of POTELIGEO is 1 mg/kg administered as an intravenous infusion over at least 60 minutes. Administer on days 1, 8, 15, and 22 of the first 28-day cycle, then on days 1 and 15 of each subsequent 28-day cycle until disease progression or unacceptable toxicity. Administer POTELIGEO within 2 days of the scheduled dose.
If a dose is missed, administer the next dose as soon as possible and resume dosing schedule. Do not administer POTELIGEO subcutaneously or by rapid intravenous administration. Recommended Premedications Administer premedication with diphenhydramine and acetaminophen for the first POTELIGEO infusion.
Preparation and Administration Preparation Visually inspect drug product solution for particulate matter and discoloration prior to administration. POTELIGEO is a clear to slightly opalescent colorless solution. Discard the vial if cloudiness, discoloration, or particulates are observed. Calculate the dose (mg/kg) and number of vials of POTELIGEO needed to prepare the infusion solution based on patient weight.
Aseptically withdraw the required volume of POTELIGEO into the syringe and transfer into an intravenous (IV) bag containing 0.9% Sodium Chloride Injection, USP. The final concentration of the diluted solution should be between 0.1 mg/mL to 3 mg/mL. Mix diluted solution by gentle inversion. Do not shake. Discard any unused portion left in the vial.
The diluted solution is compatible with polyvinyl chloride (PVC) or polyolefin (PO) infusion bags. Administration Administer infusion solution over at least 60 minutes through an intravenous line containing a sterile, low protein binding, 0.22 micron (or equivalent) in-line filter. Do not mix POTELIGEO with other drugs.
Do not co-administer other drugs through the same intravenous line. Storage of Diluted Solution After preparation, infuse the POTELIGEO solution immediately, or store under refrigeration at 2°C to 8°C (36°F to 46°F) for no more than 24 hours from the time of infusion preparation. Do not freeze. Do not shake.

Safety data
Reported adverse events (FAERS)
Liver injury (LiverTox)
CLikelihood score C: Probable cause of clinically apparent liver injury largely due to reactivation of hepatitis B and induction of autoimmune conditions.
Mogamulizumab is a humanized monoclonal antibody to the T cell CC chemokine receptor 4 which is used to treat peripheral and cutaneous T-cell lymphomas. Mogamulizumab is associated with a low rate of serum enzyme elevations during treatment and has been linked to several instances of reactivation of hepatitis B.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are no available data on POTELIGEO use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. In an animal reproduction study, administration of mogamulizumab-kpkc to pregnant cynomolgus monkeys from the start of organogenesis through delivery did not show a potential for adverse developmental outcomes at maternal systemic exposures 27 times the exposure in patients at the recommended dose, based on AUC ( see Data ). In general, IgG molecules are known to cross the placental barrier and in the monkey reproduction study mogamulizumab-kpkc was detected in fetal plasma.
Therefore, POTELIGEO has the potential to be transmitted from the mother to the developing fetus. POTELIGEO is not recommended during pregnancy or in women of childbearing potential not using contraception. 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 estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively.
Data Animal Data The effects of mogamulizumab-kpkc on embryo-fetal development were evaluated in 12 pregnant cynomolgus monkeys that received mogamulizumab-kpkc once weekly by intravenous administration from the start of organogenesis through delivery at an exposure level 27 times higher than the clinical dose. Mogamulizumab-kpkc administration did not show a potential for embryo-fetal lethality, teratogenicity, or fetal growth retardation and did not result in spontaneous abortion or increased fetal death.
In surviving fetuses (10 of 12 compared with 11 of 12 in the control group) of cynomolgus monkeys treated with mogamulizumab-kpkc, a decrease in CCR4-expressing lymphocytes due to the pharmacological activity of mogamulizumab-kpkc was noted; there were no apparent mogamulizumab-kpkc -related external, visceral, or skeletal abnormalities.
Breastfeeding (LactMed)
No information is available on the passage of mogamulizumab into breastmilk. Because mogamulizumab is a large protein molecule with a molecular weight of 149,000 Da, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. Until more data become available, mogamulizumab injection should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.
