5 WARNINGS AND PRECAUTIONS
5.1 For Intravenous Use Only
Fatal if Given by Other Routes. Death has occurred with intrathecal use.
5.2 Extravasation Tissue Injury
Only administer through a secure and free-flowing venous access line. If extravasation is suspected, discontinue infusion immediately and consider local treatment measures.
5.3 Neurologic Toxicity
Sensory and motor neuropathies are common and are cumulative. Monitor patients for symptoms of neuropathy, such as hypoesthesia, hyperesthesia, paresthesia, hyporeflexia, areflexia, neuralgia, jaw pain, decreased vibratory sense, cranial neuropathy, ileus, burning sensation, arthralgia, myalgia, muscle spasm, or weakness, both before and during treatment. Orthostatic hypotension may occur. The risk of neurologic toxicity is greater if Vincristine is administered to patients with preexisting neuromuscular disorders or when other drugs with risk of neurologic toxicity are being given. In the studies of relapsed and/or refractory adult ALL patients, Grade ≥ 3 neuropathy events occurred in 32.5% of patients. Worsening neuropathy requires dose delay, reduction, or discontinuation of Vincristine [see Dosage and Administration ].
Monitor complete blood counts prior to each dose of Vincristine. If Grade 3 or 4 neutropenia, thrombocytopenia, or anemia develops, consider Vincristine dose modification or reduction as well as supportive care measures.
5.5 Tumor Lysis Syndrome
Tumor lysis syndrome may occur in patients with ALL receiving Vincristine. Anticipate, monitor for, and manage.
5.6 Constipation and Bowel Obstruction
Ileus, bowel obstruction, and colonic pseudo-obstruction have occurred. Vincristine can cause constipation [see Adverse Reactions (6) ]. Institute a prophylactic bowel regimen to mitigate potential constipation, bowel obstruction, and/or paralytic ileus, considering adequate dietary fiber intake, hydration, and routine use of stool softeners, such as docusate. Additional treatments, such as senna, bisacodyl, milk of magnesia, magnesium citrate, and lactulose may be considered.
Vincristine can cause severe fatigue. Vincristine dose delay, reduction, or discontinuation may be necessary.
5.8 Hepatic Toxicity
Fatal liver toxicity and elevated levels of aspartate aminotransferase have occurred. Elevated levels of aspartate aminotransferase of Grade ≥3 occurred in 6-11% of patients in clinical trials. Monitor hepatic function tests. Reduce or interrupt Vincristine for hepatic toxicity.
5.9 Embryofetal Toxicity
Vincristine can cause fetal harm when administered to a pregnant woman. Vincristine liposome injection was teratogenic or caused embryo-fetal death in animals. Women of childbearing potential should avoid becoming pregnant while being treated with Vincristine. There are no adequate and well-controlled studies of Vincristine in pregnant women and there were no reports of pregnancy in any of the clinical studies in the Vincristine clinical development program. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus .
6 ADVERSE REACTIONS
The following adverse reactions are also discussed in other sections of the labeling:
Most commonly reported adverse reactions (incidence ≥ 30%) in clinical studies include constipation, nausea, pyrexia, fatigue, peripheral neuropathy, febrile neutropenia, diarrhea, anemia, decreased appetite, and insomnia (6.1).

6.1 Clinical Trials Safety Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Integrated Summary of Safety in Relapsed and/or Refractory Ph- Adult Acute Lymphoblastic Leukemia
Vincristine, at a dose of 2.25 mg/m2 weekly, was studied in a total of 83 patients in two trials: study 1 and study 2. Adverse reactions were observed in 100% of patients. The most common adverse reactions (>30%) were constipation (57%), nausea (52%), pyrexia (43%), fatigue (41%), peripheral neuropathy (39%), febrile neutropenia (38%), diarrhea (37%), anemia (34%), decreased appetite (33%), and insomnia (32%).
Adverse reactions of Grade 3 or greater were reported in 96% of patients. Adverse reactions of Grade 3 or greater and occurring in ≥ 5% of patients are summarized in Table 2.
A total of 75.9% of patients experienced serious adverse events (SAEs) during the studies. The most commonly reported SAEs included febrile neutropenia (20.5%), pyrexia (13.3%), hypotension (7.2%), respiratory distress (6.0%), and cardiac arrest (6.0%).
Dose reduction, delay, or omission occurred in 53% of patients during the treatment.
Twenty-eight percent of patients experienced adverse reactions leading to treatment discontinuation. The most common adverse reactions that caused treatment discontinuation were peripheral neuropathy (10%), leukemia-related (7%), and tumor lysis syndrome (2%).
Adverse reactions related to neuropathy and leading to treatment discontinuation were decreased vibratory sense, facial palsy, hyporeflexia, constipation, asthenia, fatigue, and musculoskeletal pain, each reported in at least 1 patient.
Deaths occurred in 23% of patients in study 1. The non-leukemia related causes of deaths were brain infarct (1), intracerebral hemorrhage (2), liver failure (1), multi system organ failure (2), pneumonia and septic shock (3), respiratory failure (4), pulmonary hemorrhage (1), and sudden cardiac death (1).
7 DRUG INTERACTIONS
No formal drug interaction studies have been conducted with Vincristine. Vincristine is expected to interact with drugs known to interact with non-liposomal Vincristine.
Simultaneous oral or intravenous administration of phenytoin and antineoplastic chemotherapy combinations that included non-liposomal Vincristine have been reported to reduce blood levels of phenytoin and to increase seizure activity.
Vincristine is expected to interact with drugs known to interact with non-liposomal Vincristine.
7.1 CYP3A Interactions
Vincristine, the active agent in Vincristine, is a substrate for cytochrome P450 3A isozymes (CYP3A); therefore, the concomitant use of strong CYP3A inhibitors should be avoided (e.g., ketoconazole, itraconazole, voriconazole, posaconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin). Similarly, the concomitant use of strong CYP3A inducers should be avoided (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital, St. John's Wort).
7.2 P-glycoprotein Interactions
Vincristine, the active agent in Vincristine, is also a substrate for P-glycoprotein (P-gp). The effect of concomitant use of potent P-gp inhibitors or inducers has not been investigated; it is likely that these agents will alter the pharmacokinetics or pharmacodynamics of Vincristine. Therefore the concomitant use of potent P-gp inhibitors or inducers should be avoided.
8 USE IN SPECIFIC POPULATIONS
Pediatric Use: The safety and effectiveness of Vincristine in pediatric patients has not been established
Pregnancy Category D [see Warnings and Precautions (5.9) ]
Based on its mechanism of action and findings from animal studies, Vincristine can cause fetal harm when administered to pregnant women.
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. In an embryofetal developmental study, pregnant rats were administered Vincristine liposome injection intravenously during the period of organogenesis at Vincristine doses of 0.022 to 0.09 mg/kg/day. Drug-related adverse effects included fetal malformations (skeletal and visceral), decreases in fetal weights, increased numbers of early resorptions and post-implantation losses, and decreased maternal body weights Malformations were observed at doses ≥ 0.044 mg/kg/day in animals at systemic exposures approximately 20-40% of those reported in patients at the recommended dose.
8.3 Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue the drug taking into account the importance of the drug to the mother.
8.4 Pediatric Use
The safety and effectiveness of Vincristine in pediatric patients have not been established.
8.5 Geriatric Use
Safety and effectiveness in elderly individuals have not been established. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
8.6 Renal Impairment
The influence of renal impairment on the safety, efficacy, and pharmacokinetics of Vincristine has not been evaluated.
8.7 Hepatic Impairment
Non-liposomal Vincristine is excreted primarily by the liver. The influence of severe hepatic impairment on the safety and efficacy of Vincristine has not been evaluated.
The pharmacokinetics of Vincristine was evaluated in patients with moderate hepatic dysfunction (Child-Pugh B) secondary to melanoma liver metastases. The dose-adjusted maximum plasma concentration (Cmax) and area under the concentration-time curve (AUC) of Vincristine in patients with moderate hepatic impairment was comparable to the Cmax and AUC of patients with ALL who had otherwise normal hepatic function.
When Vincristine (vinCRIStine sulfate LIPOSOME injection) was administered at a dose of 2.4 mg/m2, severe toxicities including motor neuropathy of Grade 3, grand mal seizure of Grade 4, and elevated aspartate aminotransferase and hyperbilirubinemia of Grade 4 were reported in 1 patient each. There is no known antidote for overdosage.
Vincristine (vinCRIStine sulfate LIPOSOME injection) is vincristine encapsulated in sphingomyelin/cholesterol liposomes for intravenous administration.
The active ingredient in Vincristine is Vincristine. Vincristine is a vinca alkaloid isolated as a 1:1 sulfate salt from the periwinkle plant (Catharanthus roseus). It is a hygroscopic, white to slightly yellowish crystalline powder that is soluble in water. It has a molecular weight of 923.04 (salt form) / 824.98 (base form) and a molecular formula of C46H56N4O10 - H2SO4. The chemical name for Vincristine is 22-oxovincaleukoblastine and it has the following chemical structure:
Vincristine is encapsulated in a Sphingomyelin/Cholesterol liposome. The lipid components in the liposome are sphingomyelin and cholesterol at a molar ratio of approximately 60:40 (mol:mol).
After preparation, each vial of Vincristine contains 5 mg Vincristine, 500 mg mannitol, 73.5 mg sphingomyelin, 29.5 mg cholesterol, 36 mg sodium citrate, 38 mg citric acid, 355 mg sodium phosphate, and 225 mg sodium chloride.
Vincristine (vinCRIStine sulfate LIPOSOME injection) appears as a white to off-white, translucent suspension, essentially free of visible foreign matter and aggregates, comprised of sphingomyelin/cholesterol liposomes, with an approximate liposome mean diameter of 100 nm. Greater than 95% of the drug is encapsulated in the liposomes.
The Vincristine Kit component vials for the preparation of Vincristine (vinCRIStine sulfate LIPOSOME injection) include:
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Vincristine is a sphingomyelin/cholesterol liposome-encapsulated formulation of Vincristine. Non-liposomal Vincristine binds to tubulin, altering the tubulin polymerization equilibrium, resulting in altered microtubule structure and function. Non-liposomal Vincristine stabilizes the spindle apparatus, preventing chromosome segregation, triggering metaphase arrest and inhibition of mitosis.
The plasma pharmacokinetics of Vincristine was investigated in 13 adult patients with relapsed ALL who received a Vincristine dose of 2.25 mg/m2 administered as a 1-hour intravenous infusion. The calculated pharmacokinetic parameters for total plasma Vincristine are given in Table 3. The Vincristine levels reported in Table 3 reflect liposome-encapsulated drug that may not be immediately bioavailable and may not be directly comparable to plasma levels of Vincristine after administration of non-liposomal Vincristine, which is immediately bioavailable.
The plasma clearance (CL) of Vincristine is slow, 345 mL/h, at a dose of 2.25 mg/m2. This is in comparison to the rapid clearance of non-liposomal Vincristine at 189 mL/min/m2 (11,340 mL/h). The slow clearance of Vincristine contributes to a much higher AUC for Vincristine relative to non-liposomal Vincristine.
Following intravenous administration of Vincristine, urinary excretion was a minor route of elimination for Vincristine and its metabolite. Less than 8% of the administered Vincristine dose was eliminated in urine over a 96-hour observation period, which is similar to the urinary excretion of non-liposomal Vincristine. Following non-liposomal Vincristine infusion, the main route of Vincristine excretion was the fecal route, accounting for 69% of the administered dose over 72 hours.
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
No carcinogenicity studies have been conducted with Vincristine or non-liposomal Vincristine. Based on the mechanism of action and genotoxicity findings in nonclinical studies conducted with non-liposomal Vincristine, Vincristine may be carcinogenic.
No genotoxicity studies have been conducted with Vincristine. Non-liposomal vincristine was genotoxic in some in vitro and in vivo studies.
The single- and repeat-dose animal toxicology study results indicate that Vincristine can impair male fertility, consistent with the literature on non-liposomal Vincristine. Administration of vincristine liposome injection causes testicular degeneration and atrophy, and epididymal aspermia in rats.
Gonadal dysfunction has been reported in both male and female post-pubertal patients who received multi-agent chemotherapy including non-liposomal Vincristine. The degree to which testicular or ovarian functions are affected is age-, dose-, and agent-dependent. Recovery may occur in some but not all patients.
13.2 Animal Toxicology and/or Pharmacology
In a repeat-dose comparative toxicology study in rats, Vincristine liposome injection or non-liposomal Vincristine was administered to animals intravenously once per week for 6 weeks. Clinical signs of toxicity consistent with neurotoxicity were greater with Vincristine liposome injection than with non-liposomal Vincristine at equal Vincristine doses of 2 mg/m2/week and included uncoordinated movements, weakness, reduced muscle tone, and limited usage of the limbs. Neurological testing indicated drug-induced peripheral neurotoxicity with both drugs. Based on the histopathology examination after 6 weekly doses, Vincristine liposome injection induced greater peripheral neurotoxicity (nerve fiber degeneration) and secondary skeletal muscle atrophy than the equal dose of non-liposomal Vincristine. In a separate tissue distribution study in rats, administration of 2 mg/m2 of intravenous liposomal or non-liposomal Vincristine showed greater accumulation of Vincristine in sciatic and tibial nerves (as well as the lymph nodes, spleen, and bone marrow) of the animals following Vincristine liposome injection.
14 CLINICAL STUDIES
14.1 Acute Lymphoblastic Leukemia
Vincristine was studied in an international, open-label, multi-center, single-arm trial (Study 1). Eligible patients were 18 years of age or older with Philadelphia chromosome negative ALL in second or greater relapse or whose disease progressed after two or greater treatment lines of anti-leukemia therapy. Patients had to have achieved a complete remission (CR) to at least one prior anti-leukemia chemotherapy, defined by a leukemia-free interval of equal or more than 90 days. Patients were not eligible for immediate hematopoietic stem cell transplantation (HSCT) at the time of screening and enrollment.
Patients received intravenous Vincristine monotherapy at 2.25 mg/m2 over 60 minutes every 7 days. Concomitant corticosteroids were not permitted beyond Day 5.
The treated population included 65 patients who received at least 1 dose of Vincristine. All of the treated patients had received prior Vincristine and 80% had evidence of residual neuropathy at study baseline. Among treated patients, 51% were male, 86% were white, 45% were under 30 years of age, 11% were age 65 or older, 48% had undergone prior HSCT, 51% had received 3 or more prior therapies, and 45% were refractory to their immediate prior therapy. Disease characteristics were 85% precursor B-cell ALL and 15% precursor T-cell ALL. In addition, 22 of 65 (34%) treated patients did not receive asparaginase products prior to enrollment. Efficacy results are shown in Table 4.
