Levoleucovorin injection is used in adults and children to prevent harmful effects of methotrexate (Trexall) when methotrexate is used to treat osteosarcoma (cancer that forms in bones). Levoleucovorin injection is also used to treat adults and children who have accidentally received an overdose of methotrexate or similar medications or who are not able to eliminate these medications properly from their bodies. Levoleucovorin injection is also used with fluorouracil (5-FU, a chemotherapy medication) to treat adults with colorectal cancer (cancer that begins in the large intestine) that has spr...

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Effects of Leucovorin Products on Other Drugs Antiepileptic Drugs Folic acid in large amounts may counteract the antiepileptic effect of phenobarbital, phenytoin and primidone and increase the frequency of seizures in susceptible children. It is not known whether folinic acid has the same effects; however, both folic and folinic acids share some common metabolic pathways. Monitor patients taking folinic acid in combination with antiepileptic drugs.
Fluorouracil Leucovorin products increase the toxicity of fluorouracil. Do not initiate or continue therapy with levoleucovorin and fluorouracil in patients with symptoms of gastrointestinal toxicity until those symptoms have resolved. Monitor patients with diarrhea until the diarrhea has resolved, as rapid deterioration leading to death can occur [see Warnings and Precautions ( 5.2 )].
Trimethoprim-Sulfamethoxazole The concomitant use of d,l -leucovorin with trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis jiroveci pneumonia in patients with HIV infection was associated with increased rates of treatment failure and morbidity in a placebo-controlled study [see Warnings and Precautions ( 5.3 )] .

🆘 Overdosage ▾
2.4Recommended Dosage for Overdosage of Folic Acid Antagonists or Impaired Methotrexate Elimination Start levoleucovorin injection as soon as possible after an overdosage of methotrexate or within 24 hours of methotrexate administration when methotrexate elimination is impaired. As the time interval between methotrexate administration and levoleucovorin injection increases, the effectiveness of levoleucovorin injection to diminish methotrexate toxicity may decrease. Administer levoleucovorin injection 7.5 mg (approximately 5 mg/m 2 ) by intravenous infusion every 6 hours until the serum methotrexate level is less than 5 x 10 -8 M (0.05 micromolar).
Monitor serum creatinine and methotrexate levels at least every 24 hours. Increase the dosage of levoleucovorin injection to 50 mg/m 2 intravenously every 3 hours and continue levoleucovorin injection at this dosage until the methotrexate level is less than 5 x 10 -8 M for the following: if serum creatinine at 24-hours increases 50% or more compared to baseline if the methotrexate level at 24-hours is greater than 5 x 10 -6 M if the methotrexate level at 48-hours is greater than 9 x 10 -7 M, Continue concomitant hydration (3 L per day) and urinary alkalinization with sodium bicarbonate.
Adjust the sodium bicarbonate dose to maintain urine pH at 7 or greater.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action High-Dose Methotrexate Therapy Levoleucovorin is the pharmacologically active isomer of 5-formyl tetrahydrofolic acid. Levoleucovorin does not require reduction by the enzyme dihydrofolate reductase in order to participate in reactions utilizing folates as a source of “one-carbon” moieties. Administration of levoleucovorin counteracts the therapeutic and toxic effects of folic acid antagonists such as methotrexate, which act by inhibiting dihydrofolate reductase.
Combination with Fluorouracil in Colorectal Cancer Levoleucovorin enhances the therapeutic and toxic effects of fluorouracil. Fluorouracil is metabolized to 5-fluoro-2'-deoxyuridine-5'-monophosphate (FdUMP), which binds to and inhibits thymidylate synthase (an enzyme important in DNA repair and replication). Levoleucovorin is converted to another reduced folate, 5,10-methylenetetrahydrofolate, which acts to stabilize the binding of FdUMP to thymidylate synthase and thereby enhancing the inhibition of thymidylate synthase.
12.3Pharmacokinetics The pharmacokinetics of levoleucovorin after intravenous administration of a 15 mg dose was studied in healthy subjects. The mean maximum serum total tetrahydrofolate (total-THF) concentrations was 1722 ng/mL (CV 39%) and the mean maximum serum (6S)-5-methyl-5,6,7,8-tetrahydrofolate concentrations was 275 ng/mL (CV 18%) observed around 0.9 hours post injection. Distribution Exploratory studies show that small quantities of systemically administered leucovorin enter the cerebrospinal fluid (CSF), primarily as its major metabolite 5-methyltetrahydrofolate (5-MTHFA).
In humans, the CSF levels of 5-MTHFA remain 1-3 orders of magnitude lower than the usual methotrexate concentrations following intrathecal administration. Elimination The mean terminal half-life was 5.1 hours for total-THF and 6.8 hours for (6S)-5-methyl-5,6,7,8-tetrahydrofolate. Drug Interaction Studies The mean dose-normalized steady-state plasma concentrations for both levoleucovorin and 5-methyl-THF were comparable whether fluorouracil (370 mg/m 2 /day as an intravenous bolus) was given in combination with levoleucovorin (250 mg/m 2 and 1000 mg/m 2 as a continuous intravenous infusion for 5.5 days) or with d,l -leucovorin (500 mg/m 2 as a continuous intravenous infusion for 5.5 days).

📋 Description ▾
11 DESCRIPTION Levoleucovorin is a folate analog and the pharmacologically active levo-isomer of d,l -leucovorin. The chemical name of levoleucovorin calcium is calcium (6 S )-N-{4-[[(2-amino-5-formyl-1,4,5,6,7,8-hexahydro-4-oxo-6-pteridinyl)methyl] amino]benzoyl}- L -glutamate mixed hydrates. The molecular formula is C 20 H 21 CaN 7 O 7 ● nH 2 O (n = 3 to 6) and the molecular weight is 565.6 to 619.6.
The molecular structure is: Levoleucovorin Injection, for intravenous use is supplied as a sterile colorless to yellow, clear solution of either 175 mg levoleucovorin in 17.5 mL or 250 mg levoleucovorin in 25 mL per single-dose vial. Each mL contains 10 mg levoleucovorin (equivalent to 10.8 mg levoleucovorin calcium, on anhydrous basis) and 8.3 mg sodium chloride. Sodium hydroxide is used for pH adjustment to pH 8.0 (6.5 to 8.5). molecular structure
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics The pharmacokinetics of levoleucovorin after intravenous administration of a 15 mg dose was studied in healthy subjects. The mean maximum serum total tetrahydrofolate (total-THF) concentrations was 1722 ng/mL (CV 39%) and the mean maximum serum (6S)-5-methyl-5,6,7,8-tetrahydrofolate concentrations was 275 ng/mL (CV 18%) observed around 0.9 hours post injection. Distribution Exploratory studies show that small quantities of systemically administered leucovorin enter the cerebrospinal fluid (CSF), primarily as its major metabolite 5-methyltetrahydrofolate (5-MTHFA).
In humans, the CSF levels of 5-MTHFA remain 1-3 orders of magnitude lower than the usual methotrexate concentrations following intrathecal administration. Elimination The mean terminal half-life was 5.1 hours for total-THF and 6.8 hours for (6S)-5-methyl-5,6,7,8-tetrahydrofolate. Drug Interaction Studies The mean dose-normalized steady-state plasma concentrations for both levoleucovorin and 5-methyl-THF were comparable whether fluorouracil (370 mg/m 2 /day as an intravenous bolus) was given in combination with levoleucovorin (250 mg/m 2 and 1000 mg/m 2 as a continuous intravenous infusion for 5.5 days) or with d,l -leucovorin (500 mg/m 2 as a continuous intravenous infusion for 5.5 days).
🔬 Clinical Studies ▾
14 CLINICAL STUDIES
14.1Rescue after High-Dose Methotrexate Therapy in Patients with Osteosarcoma The efficacy of levoleucovorin rescue following high-dose methotrexate was evaluated in 16 patients aged 6 to 21 years who received 58 courses of therapy for osteogenic sarcoma. High-dose methotrexate was one component of several different combination chemotherapy regimens evaluated across several trials. Methotrexate 12 grams/m 2 as an intravenous infusion over 4 hours was administered to 13 patients, who received levoleucovorin 7.5 mg by intravenous infusion every 6 hours for 60 hours or longer beginning 24 hours after completion of methotrexate.
Three patients received methotrexate 12.5 grams/m 2 intravenously over 6 hours, followed by levoleucovorin 7.5 mg by intravenous infusion every 3 hours for 18 doses beginning 12 hours after completion of methotrexate. The mean number of levoleucovorin doses per course was 18.2 and the mean total dose per course was 350 mg. The efficacy of levoleucovorin rescue following high-dose methotrexate was based on the adverse reaction profile [see Adverse Reactions ( 6.1 )].
14.2Metastatic Colorectal Cancer In a randomized clinical study conducted by Mayo Clinic and North Central Cancer Treatment Group (NCCTG) in patients with metastatic colorectal cancer comparing d,l -leucovorin 200 mg/m 2 and fluorouracil 370 mg/m 2 versus d,l -leucovorin 20 mg/m 2 and fluorouracil 425 mg/m 2 versus fluorouracil 500 mg/m 2 , with all drugs administered by intravenous infusion daily for 5 days every 28 to 35 days, response rates were 26% (p=0.04 versus fluorouracil alone), 43% (p=0.001 versus fluorouracil alone) and 10%, respectively.
Respective median survival times were 12.2 months (p=0.037), 12 months (p=0.050), and 7.7 months. The low dose d,l -leucovorin regimen was associated with a statistically significant improvement in weight gain of more than 5%, relief of symptoms, and improvement in performance status. The high dose d,l -leucovorin regimen was associated with a statistically significant improvement in performance status and trended toward improvement in weight gain and in relief of symptoms but these were not statistically significant.
In a second randomized clinical study conducted by Mayo Clinic and NCCTG, the fluorouracil alone arm was replaced by a regimen of sequentially administered methotrexate, fluorouracil, and d,l -leucovorin. Response rates with d,l -leucovorin 200 mg/m 2 and fluorouracil 370 mg/m 2 versus d,l -leucovorin 20 mg/m 2 and fluorouracil 425 mg/m 2 versus sequential methotrexate and fluorouracil and d,l -leucovorin were respectively 31% (p≤0.01), 42% (p≤0.01), and 14%. Respective median survival times were 12.7 months (p≤0.04), 12.7 months (p≤0.01), and 8.4 months.
There was no statistically significant difference in weight gain of more than 5% or in improvement in performance status was seen between the treatment arms. A randomized controlled trial conducted by NCCTG in patients with metastatic colorectal cancer failed to show superiority of a regimen of fluorouracil + levoleucovorin to fluorouracil + d,l -leucovorin in overall survival. Patients were randomized to fluorouracil 370 mg/m 2 intravenously and levoleucovorin 100 mg/m 2 intravenously, both daily for 5 days, or to fluorouracil 370 mg/m 2 intravenously and d,l -leucovorin 200 mg/m 2 intravenously, both daily for 5 days.
Treatment was repeated week 4 and week 8, and then every 5 weeks until disease progression or unacceptable toxicity.
