Drug Formulary information is intended for use by healthcare professionals. It is not intended to be medical advice. Some of the information, including information about funding for cancer drugs, does not apply to all patients. Cancer treatment plans are unique to each patient. If you are a patient, please speak with your healthcare team to understand how this information applies to you.
XELOX+BEVA
Small bowel and appendix
Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR). Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.

oxaliplatin | 130 mg /m² | IV | Day 1 |
capecitabine | 1000 mg /m² | PO | BID, Days 1 to 14 |
Note: a dose of capecitabine 750 mg/m2 PO BID was used in a small phase 2 study in small bowel cancer (Overman MJ et al.)
Moderate
No routine prophylaxis for capecitabine
Also refer to CCO Antiemetic Recommendations.
Screen for hepatitis B virus in all cancer patients starting systemic treatment. Refer to the hepatitis B virus screening and management guideline.
Oxaliplatin premedication (prophylaxis for infusion reactions):
- There is insufficient evidence that routine prophylaxis with pre-medications reduces IR rates.
- Consider corticosteroids and H1-receptor antagonists ± H2-receptor antagonists in high-risk patients (i.e. ≥ cycle 6, younger age, female gender, prior platinum exposure, platinum-free interval ≥ 3 years).
Bevacizumab premedication (prophylaxis for infusion reactions):
- Routine primary prophylaxis is not recommended; the use of secondary prophylaxis pre-medications should be based on clinical judgement.
Other Supportive Care:
- Topical emollients (e.g. hand creams, udder balm) therapy may ameliorate the manifestations of hand-foot syndrome in patients receiving capecitabine.
- Standard antidiarrheal agents (e.g. loperamide) should be initiated, as medically appropriate, as early as possible.
- Patients should be counselled about cold avoidance prior to receiving oxaliplatin, since cold temperatures can precipitate or exacerbate acute neurological symptoms.
Doses should be modified according to the protocol by which the patient is being treated.
Patients should be tested for DPD deficiency before starting treatment with capecitabine. Refer to the DPD Deficiency Guidance for Clinicians for more information.
In patients with unrecognized DPD deficiency, acute, life-threatening toxicity may occur; if acute grade 2-4 toxicity develops, treatment should be stopped immediately and permanent discontinuation considered based on clinical assessment of the toxicities.
Bevacizumab should not be initiated in patients with recurrent hemoptysis, uncontrolled hypertension or wounds that require healing.
Prior to treatment, a dental evaluation should be performed and major dental procedures completed.
Dosage with toxicity
Do not retreat until neutrophils ≥ 1.5 x 109 /L, platelet counts ≥ 100 x 109 /L and major organ toxicity has resolved to ≤ grade 1.

Dosage in the Elderly
For oxaliplatin, patients ≥ 65 years had a higher incidence of GI toxicity, myelosuppression, syncope and fatigue. No dose adjustments were needed but caution should be exercised.
For capecitabine, older patients are more susceptible to the effects of fluoropyrimidine-based therapies with increased grade 3 / 4 adverse effects, especially when used in combination. Starting dosage adjustment is not recommended, but dose modifications should be performed for toxicity (see tables above).
Use bevacizumab with caution; patients > 65 years old have an increased risk of arterial thrombotic events as well as myelosuppression, fatigue, proteinuria, hypertension, dizziness, dysphonia, anorexia and GI effects (except gastrointestinal perforation).
Dosage based on gender
Females were observed to have higher number of severe adverse effects with oxaliplatin than males.
Refer to oxaliplatin, capecitabine, bevacizumab drug monograph(s) for additional details of adverse effects

Refer to oxaliplatin, capecitabine, bevacizumab drug monograph(s) for additional details
-
Concomitant use with sorivudine or analogues is contraindicated, given the increased risk of capecitabine toxicity (may be fatal). Wait at least 4 weeks after sorivudine (or chemically related analogues) treatment before starting capecitabine.
-
Avoid concomitant administration with phenytoin; capecitabine may increase levels. Monitor phenytoin levels if must be given together.
-
Do not use with diuretics in patients who are receiving bevacizumab and platinum-based chemotherapy (oxaliplatin).
-
Monitor PT/INR when this treatment is administered with warfarin or other anticoagulants; adjust anticoagulant dose accordingly.
-
Caution with the use of proton pump inhibitors and monitor for reduced effectiveness of capecitabine; consider switching to a magnesium and aluminum hydroxide-containing antacid.
-
Caution and monitor with the coadministration of leucovorin as this may increase capecitabine toxicity.
- Monitor for toxicity when using oxaliplatin with other nephrotoxic drugs, QT-prolonging drugs or drugs associated with rhabdomyolysis.
Refer to oxaliplatin, capecitabine, bevacizumab drug monograph(s) for additional details
Administration:
Bevacizumab
Different bevacizumab products are not interchangeable.
-
Do not administer as an IV push or bolus.
-
Bevacizumab infusions should not be administered or mixed with dextrose or glucose solutions due to potential for drug degradation.
-
Mix in 100 mL bag NS. (Final concentration should be 1.4 -16.5 mg/mL).
-
Compatible with PVC or polyolefin bags.
-
Do not shake. Should not be mixed or diluted with other drugs.
-
Infuse over 90 minutes as loading dose, if tolerated next infusion can be given over 60 minutes; can thereafter be given over 30 minutes as maintenance dose
-
Bevacizumab rapid infusion (over 10 minutes) has safely been administered with no significant increase in infusion reactions (for 5mg/kg and 7.5mg/kg doses).
-
Refrigerate unopened vials and protect from light; do not freeze.
Oxaliplatin
-
Oxaliplatin is administered by intravenous infusion.
-
May be mixed in 250-500 mL bag (D5W only). Do not mix with NS, chloride containing or alkaline solutions.
-
Administer by slow infusion. Concentration must be between 0.2 to 0.7 mg/mL
-
Infuse IV over 2 hours. Increasing infusion time to 6 hours may decrease acute toxicity such as pharyngolaryngeal dysesthesia.
-
Do not mix oxaliplatin with other drugs in the same infusion bag or infusion line.
-
If another drug is given before oxaliplatin, flush infusion line with D5W before giving oxaliplatin. Flush the line with D5W after oxaliplatin before giving a subsequent drug.
-
The compatibility of oxaliplatin solution for infusion has been tested with representative, PVC-based, administration sets.
-
Do not use with injection equipment containing aluminum, as this can degrade platinum compounds.
-
Unopened vials should be stored at 15-30°C; protect from light.
Capecitabine
-
Oral self-administration; drug available by outpatient prescription.
-
Doses are given orally approximately 12 hours apart, within 30 minutes after the end of a meal.
-
Swallow tablets whole; do not crush or cut tablets.
-
If a capecitabine dose is missed, skip this and give the next dose at the usual time. Missed or omitted doses should not be replaced.
-
Store tablets at 15ºC to 30ºC in the original package.
Also refer to the CCO guideline for detailed description of Management of Cancer Medication-Related Infusion Reactions.
