Combined therapy with oral capecitabine^{† [off-label]} is a reasonable choice (accepted, treatment option) as adjuvant therapy following complete resection of primary tumor in patients with stage III colon cancer.^{10001 10002 10003 10006 10007 10008 10011 10012 10013 10014 10015 10016 10018}

Used in combination with fluorouracil and leucovorin for the treatment of advanced carcinoma of the colon or rectum.¹ Evaluated as first-line therapy for unresectable colorectal cancer^{1 11} and as second-line therapy in patients whose disease recurred or progressed during or within 6 months following first-line therapy with fluorouracil, leucovorin, and irinotecan.¹

Oxaliplatin Dosage and Administration

General

• Administer on day 1 as part of a 2-day combination regimen.^{1 24}

• Premedication with antiemetics, including selective inhibitors of type 3 serotonergic (5-HT₃) receptors (e.g., dolasetron, granisetron, ondansetron) with or without dexamethasone, recommended prior to each 2-day cycle.¹

• Hydration prior to administration not necessary.¹

• Handle cautiously (e.g., use gloves) to avoid exposure to oxaliplatin during preparation of IV solutions.¹ Immediately treat accidental contact; wash skin thoroughly with soap and water or flush mucosa with copious amounts of water.¹ Consult specialized references for procedures for proper handling and disposal of antineoplastics.

Cautions for Oxaliplatin

Contraindications

• History of hypersensitivity reactions to oxaliplatin, any ingredient in the formulation, or other platinum-containing compounds.^{1 7}

Warnings/Precautions

Warnings

Hypersensitivity Reactions

Risk of anaphylaxis and other hypersensitivity reactions (e.g., rash, urticaria, erythema, pruritus, flushing, infusion-associated diarrhea, dyspnea, bronchospasm, diaphoresis, hypotension, chest pain, disorientation, syncope).^{1 24} (See Boxed Warning.) Can be fatal.¹ Similar in nature and severity to those associated with other platinum-containing antineoplastic agents.¹ May occur within minutes following administration and during any cycle of therapy.¹

If a hypersensitivity reaction occurs, immediately and permanently discontinue the drug and initiate appropriate treatment.¹

Other Warnings and Precautions

Consider the usual cautions, precautions, and contraindications of fluorouracil and leucovorin therapy.⁷

Neuropathy

Consistently associated with acute or delayed peripheral neuropathy.^{1 2 3 4} Duration and severity increase with increasing oxaliplatin cumulative dosage.^{2 7}

Acute, reversible sensory neuropathy (e.g., acute transient paresthesia,^{1 3} dysesthesia,^{1 3} and hypoesthesia in hands, feet, perioral area, or throat, jaw spasm, abnormal tongue sensation, dysarthria, ocular pain, feeling of chest pressure¹ ) may occur within hours^{1 2} or 2 days following oxaliplatin administration, resolves within 14 days, and frequently recurs with further administration of the drug.¹ Acute neuropathy may be precipitated or exacerbated by exposure to cold temperature or cold objects;^{1 2} avoid ice (e.g., for mucositis prophylaxis) during oxaliplatin infusion.¹

Possible acute pharyngolaryngeal dysesthesia;^{1 3} incidence may be reduced by prolonging duration of infusion.^{2 7}

Delayed sensory neuropathy (e.g., paresthesias, dysesthesias, hypoesthesias, impaired proprioception)^{1 2} can occur without any prior acute neuropathic event and typically persists for >14 days following oxaliplatin administration;¹ symptoms may improve upon discontinuance of therapy.¹

Insufficient evidence to support use of any preventive strategy (e.g., intermittent [“stop and go”] oxaliplatin regimens, potential neuromodulatory agents).¹⁴

Hematologic Effects

Possible grade 3 or 4 neutropenia, febrile neutropenia, or infection with severe neutropenia.¹ Sepsis, neutropenic sepsis, and septic shock, sometimes fatal, also reported.¹

Monitor CBCs at baseline, prior to each cycle of therapy, and as clinically indicated.¹ Do not administer oxaliplatin until neutrophil counts reach ≥1500/mm³ and platelet counts reach ≥75,000/mm³.¹ If sepsis or septic shock occurs, interrupt therapy.¹

Posterior Reversible Encephalopathy Syndrome (PRES)

PRES, with or without concomitant hypertension, reported.¹ Manifestations include headache, altered mental status, seizure, and visual disturbance (e.g., vision loss, blurred vision).¹

If PRES is suspected, perform MRI for diagnostic evaluation.¹ If PRES is confirmed. permanently discontinue oxaliplatin.¹

Pulmonary Toxicity

Pulmonary fibrosis (sometimes fatal) reported.^{1 7} If unexplained respiratory manifestations (e.g., nonproductive cough, dyspnea, crackles, radiographic evidence of pulmonary infiltrates) develop, temporarily discontinue therapy until interstitial lung disease and pulmonary fibrosis are excluded.¹ If interstitial lung disease or pulmonary fibrosis is confirmed, permanently discontinue oxaliplatin.¹

Fatal eosinophilic pneumonia reported.¹

Hepatic Effects

Possible elevation of ALT, AST, alkaline phosphatase, or bilirubin concentrations.¹ Perform liver function tests (e.g., aminotransferases, bilirubin) at baseline, prior to each cycle of therapy, and as clinically indicated.^{1 7}

Hepatic vascular conditions (e.g., peliosis hepatis, nodular regenerative hyperplasia or sinusoidal changes, perisinusoidal fibrosis, veno-occlusive lesions) reported in patients receiving oxaliplatin in combination with fluorouracil and leucovorin.¹ Consider hepatic vascular toxicity in patients with abnormal liver function test results or portal hypertension that cannot be explained by metastases to the liver; investigate as clinically appropriate.¹

Cardiac Effects

Prolongation of the QT interval and subsequent ventricular arrhythmia, including torsades de pointes with fatal outcome, reported.¹

Avoid in patients with congenital long QT syndrome.¹ Monitor ECGs in patients with CHF, bradyarrhythmias, or electrolyte abnormalities and in those who are receiving drugs known to prolong the QT interval (i.e., class IA and III antiarrhythmics).¹ Monitor and correct serum electrolyte abnormalities prior to initiation of oxaliplatin and periodically during therapy.¹

Rhabdomyolysis

Rhabdomyolysis, which may be fatal, reported.¹

If manifestations of rhabdomyolysis (e.g., hematuria, anuria) occur, permanently discontinue oxaliplatin.¹

Hemorrhage

Possible thrombocytopenia and hemorrhage (e.g., GI bleeding, hematuria, epistaxis).¹ Rapid onset of thrombocytopenia and increased risk of hemorrhage observed in patients experiencing immune-mediated thrombocytopenia; consider discontinuance of oxaliplatin therapy if immune-mediated thrombocytopenia occurs.¹ (See Hematologic Effects under Cautions.)

Possible prolongation of PT and INR with possible hemorrhage in patients receiving anticoagulant therapy; monitor patients receiving concomitant oral anticoagulant therapy (e.g., warfarin) more frequently.¹

Fetal/Neonatal Morbidity and Mortality

Possible fetal harm; teratogenicity and embryolethality demonstrated in animals.¹ Avoid pregnancy during therapy.¹ Confirm pregnancy status prior to initiation of therapy.¹ Women of reproductive potential should use effective contraceptive methods during therapy and for at least 9 months after the last dose of the drug.¹ Men with female partners of reproductive potential should use effective contraceptive methods during therapy and for 6 months after the last dose of the drug.¹ If used during pregnancy or if patient becomes pregnant, apprise of potential fetal hazard.¹

Impairment of Fertility

Based on animal studies, may impair male and female fertility.¹

Specific Populations

Pregnancy

May cause fetal harm.¹ (See Fetal/Neonatal Morbidity and Mortality under Cautions.)

Lactation

Not known whether oxaliplatin or its metabolites are distributed into milk or if drug has any effect on milk production or the nursing infant.¹ Women should not breast-feed during therapy and for 3 months after the last dose of the drug.¹

Pediatric Use

Safety and efficacy not established in pediatric patients.^{1 7} No substantial antitumor activity reported in 69 pediatric patients with solid tumors.¹

Geriatric Use

Clearance of ultrafilterable platinum does not appear to be affected substantially by age.¹ However, incidence of certain adverse effects (i.e., diarrhea, dehydration, hypokalemia, granulocytopenia, leukopenia, grade 3 or 4 neutropenia, fatigue, syncope) was increased in geriatric patients compared with younger adults.^{1 5 7}

Efficacy (effect on disease-free survival) of oxaliplatin/fluorouracil/leucovorin versus fluorouracil/leucovorin as adjuvant therapy for colon cancer was inconclusive in patients ≥65 years of age (based on descriptive subset analysis of study data).¹

In patients receiving oxaliplatin/fluorouracil/leucovorin as first-line therapy for advanced colorectal cancer, no differences in efficacy observed in patients ≥65 years of age compared with the overall study population.¹

In patients receiving the oxaliplatin/fluorouracil/leucovorin regimen for previously treated advanced colorectal cancer, no differences in efficacy observed in patients ≥65 years of age compared with younger adults.¹

Renal Impairment

Mild or moderate renal impairment: Increases mean dose-adjusted AUC of unbound platinum following administration of oxaliplatin 85 mg/m².¹ Peak plasma concentrations of unbound platinum not altered.¹

Severe renal impairment: Increases mean dose-adjusted AUC and peak plasma concentration of unbound platinum following administration of oxaliplatin 65 mg/m²; dosage adjustment recommended.¹

Common Adverse Effects

Adjuvant combination therapy with fluorouracil and leucovorin in patients with colon cancer: Peripheral sensory neuropathy, nausea, vomiting, diarrhea, fatigue, anorexia, pyrexia, neutropenia, thrombocytopenia, anemia, elevated aminotransferase concentrations, elevated alkaline phosphatase concentrations.¹

Combination therapy with fluorouracil and leucovorin in patients with previously untreated advanced colorectal cancer: Adverse neurologic effects (i.e., neuropathy, including paresthesia, pharyngo-laryngeal dysesthesias), adverse GI effects (i.e., nausea, diarrhea, vomiting, stomatitis, anorexia, constipation, abdominal pain), fatigue, cough, alopecia, leukopenia, neutropenia, thrombocytopenia, anemia.¹

Nephrotoxic Drugs

Potential pharmacokinetic interaction (decreased clearance of platinum-containing compounds); however, this interaction has not been specifically studied.¹ Avoid concomitant use with other nephrotoxic drugs.¹

Protein-bound Drugs

Pharmacokinetic interaction with highly protein-bound drugs unlikely; platinum displacement not observed in vitro.^{1 7}

Drugs Affecting Hepatic Microsomal Enzymes

Pharmacokinetic interaction with drugs metabolized by CYP isoenzymes or those that induce or inhibit these isoenzymes unlikely.¹ However, no studies have been conducted.¹

Drugs that Prolong the QT Interval

Avoid concomitant use with other drugs known to prolong the QT interval (i.e., class IA and III antiarrhythmics).¹ (See Cardiac Effects under Cautions.)

Specific Drugs

Oxaliplatin Pharmacokinetics

Undergoes rapid and extensive nonenzymatic biotransformation to numerous platinum-containing transient reactive intermediates.^{1 2} Pharmacokinetic parameters generally expressed in terms of platinum-containing complexes rather than parent compound.²

Absorption

Special Populations

Increased mean dose-adjusted AUC of unbound platinum by 40 or 95% in patients with mild (Cl_cr of 50–80 mL/minute) or moderate (Cl_cr of 30–49 mL/minute) renal impairment, respectively, following administration of oxaliplatin 85 mg/m².¹ Mean dose-adjusted peak plasma concentration of unbound platinum not altered.¹

Increased mean dose-adjusted AUC and peak plasma concentration of unbound platinum by 342 or 38%, respectively, in patients with severe renal impairment receiving oxaliplatin 65 mg/m² compared with patients with normal renal function receiving oxaliplatin 85 mg/m².¹

Distribution

Extent

Following a 2-hour IV infusion, 85% of administered platinum is rapidly distributed into tissues or eliminated in urine; approximately 15% of administered platinum is present in systemic circulation.¹

No evidence of accumulation in plasma following usual dosage;^{1 2} possible progressive accumulation in erythrocytes.²

Not known whether oxaliplatin or its metabolites are distributed into milk.¹

Plasma Protein Binding

>90% irreversibly bound to plasma proteins (principally albumin and γ-globulins).¹

Elimination

Metabolism

Undergoes rapid and extensive nonenzymatic biotransformation; no evidence of CYP-mediated metabolism in vitro.¹

Elimination Route

Eliminated principally by renal excretion;^{1 2} renal clearance of ultrafilterable platinum appears to be directly proportional to GFR.¹

Following 2-hour IV infusion, approximately 54 or 2% of platinum-containing derivatives is excreted in urine and feces, respectively, within 5 days.¹

Half-life

Distribution and elimination of platinum-containing derivatives appears to be triphasic, with 2 relatively short distribution phases with half-lives of approximately 0.43 and 16.8 hours, respectively, and a long elimination phase with a half-life of approximately 392 hours.¹

Actions

• Antineoplastic agent;^{1 2} consists of a platinum atom complexed with 1,2-diaminocyclohexane (DACH) and a labile oxalate ligand.¹

• Must undergo nonenzymatic activation before antineoplastic activity occurs.^{1 7} In physiologic solutions, the labile oxalate ligand presumably is displaced, forming several transient reactive complexes (e.g., monoaquo DACH platinum, diaquo DACH platinum).^{1 2} These complexes covalently bind to specific DNA base sequences, producing intrastrand and interstrand DNA cross-links, which are thought to inhibit DNA replication and transcription.^{1 2}

• Cycle-phase nonspecific.¹

• Exhibits antitumor activity against colon carcinoma in vivo.¹ Exhibits synergistic antiproliferative activity with fluorouracil.^{1 2}

• Risk of hypersensitivity reactions.¹ Importance of seeking immediate medical attention if signs of severe hypersensitivity reaction (e.g., chest tightness, shortness of breath, wheezing, dizziness, faintness, angioedema) occur.¹

• Risk of neuropathy.¹ Instruct patients to avoid cold drinks and use of ice (e.g., for mucositis prophylaxis) and to cover skin prior to exposure to cold temperature or cold objects since such exposure can precipitate or exacerbate acute sensory neuropathy.¹ Importance of reading manufacturer’s patient information for further instructions to minimize exposure to cold temperature or cold objects.¹

• Risk of anemia, leukopenia, neutropenia, and thrombocytopenia; importance of informing a clinician immediately if bleeding, fever (particularly if associated with persistent diarrhea), or evidence of infection develops.¹

• Risk of posterior reversible encephalopathy syndrome and visual abnormalities (e.g., transient vision loss); such effects may affect ability to drive or operate machinery.¹

• Risk of pulmonary toxicity.¹ Importance of promptly informing clinician of any persistent or recurrent respiratory symptoms (e.g., nonproductive cough, dyspnea).¹

• Risk of hepatotoxicity.¹ Importance of informing clinician if symptoms of hepatotoxicity occur.¹

• Risk of QT-interval prolongation.¹ Importance of informing clinician if symptoms of QT-interval prolongation (e.g., syncope) occur.¹

• Risk of rhabdomyolysis.¹ Importance of promptly informing clinician if new or worsening signs or symptoms of rhabdomyolysis (e.g., dark urine, anuria, urinary retention) occur.¹

• Risk of persistent vomiting, diarrhea, or signs of dehydration.¹

• Risk of fetal harm.¹ Necessity of advising women of reproductive potential that they should use effective contraceptive methods while receiving the drug and for 9 months after the last dose of the drug.¹ Importance of advising men who are partners with women of reproductive potential to use effective methods of contraception while receiving the drug and for 6 months after the last dose of the drug.¹ Importance of patients informing their clinicians if they are pregnant or think they may be pregnant.¹ If pregnancy occurs, advise patient of potential risk to fetus.¹

• Importance of advising women to avoid breast-feeding while receiving oxaliplatin therapy and for 3 months after the last dose of the drug.¹

• Risk of impaired male and female fertility.¹

• Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as concomitant illness.¹

• Importance of informing patients of other important precautionary information.¹ (See Cautions.)
