2 Herceptin (Trastuzumab) plus Capecitabine & Cisplatin (HCX) CYCLE LENGTH AND NUMBER OF DAYS 21 days usually for 6 cycles with chemotherapy then as single agent trastuzumab until progression APPROVED INDICATIONS First line treatment of metastatic or locally advanced inoperable gastric cancer, including tumours of the gastrooesophageal junction, who over-express HER-II (IHC 2+/FISH+ or IHC 3+ only). ELIGIABILITY CRITERIA Adenocarcinoma of stomach or gastro-oesophageal junction Inoperable locally advanced and/or metastatic disease HER2-positive tumour: IHC 3+ or ICH 2+ and FISH+ Adequate organ function and ECOG performance status 2 EXCLUSION CRITERIA Inability to swallow Capecitabine tablets Chemotherapy for advanced disease Congestive heart failure or baseline LVEF <50% Creatinine clearance <60 ml/min Requirement for oxygen therapy PREMEDICATION Adequate hydration and urinary flow is essential when administering cisplatin. Patients should be weighed (with bladder empty) prior to commencing treatment and to use 20 mg of ORAL Furosemide as a diuretic given routinely if there is no contraindication. Patient should be re-weighed at the end of cisplatin (with empty bladder) and consideration given to administering a further dose of Furosemide if weight gain is more than 1.5 Kg. RECOMMENDED TAKE HOME MEDICATION Ondansetron 8mg twice daily for 2 to 3 days Dexamethasone 4mg twice daily for 1 to 3 days Metoclopramide 10 mg three times daily as required INVESTIGATIONS / MONITORING REQUIRED FBC, U&E s and LFT s. Check renal function before commencing platinum. Use EDTA or Wright formulae to estimate GFR. GFR must be above 60ml/min for cisplatin based treatment. If GFR <60ml/min discuss with an Oncology Specialist. Prior to each cycle FBC, U&E s, LFT s as required; GFR doubled checked using Wright formulae 4 monthly: ECHO / MUGA HCX-protocol-CRP10-UGI0101 v1.3 Page 2 of 6

3 REVIEW BY CLINICIAN To be reviewed by either a Nurse, Pharmacist or Clinician before every cycle. NURSE / PHARMACIST LED REVIEW On cycles where not seen by clinician. ADMINISTRATION NOTES How to take: Side effects Missed dose: Post dose vomiting: Storage/ Disposal COUNSELLING POINTS FOR ORAL CAPECITABINE Take tablets 12 hours apart, within 30 minutes after the end of meal (i.e. breakfast & evening meal.) Swallow whole with water Common side effects to discuss with patient include; diarrhoea, nausea & vomiting, stomatitis (mouth ulcers), Hand-foot syndrome(painful red swelling in hands and feet), fever or infection. If patients notice any of these advise them to stop taking treatment, contact doctor/chemotherapy day unit who will take steps to manage side effects and advise on continuing treatment. If remember half an hour after they should have taken their tablets, then take the missed dose, otherwise only take the regular dose at next scheduled time. Do not double-up doses to make up for the missed doses or take extra doses at the end of the treatment cycle. In the case of vomiting within a few hours after drug intake, never repeat the administration of the dose. Tablets should be stored in cool dry place less than 30 C. Unused medicines must be returned to hospital pharmacy for disposal Advise patients of the risk of Hand-and-foot skin-reaction (Palmar/Plantar Erythrodysesthesia) and that they should stop taking capecitabine and contact the Chemotherapy Unit if they have pain, swelling, and redness of hands and/or feet. Diarrhoea is common, and may require intervention with fluids and electrolytes if severe. If diarrhoea is a problem give loperamide 2 to 4 mg four times daily as required or codeine phosphate 30mg four times daily and stop taking Capecitabine if diarrhoea moderate/severe. If palmar- plantar erythrodysesthesia is a problem could consider pyridoxine 50 mg TDS, though the clinical evidence for efficacy of this intervention is lacking. May not need to stop trastuzumab for minor hypersensitivity e.g. reactions, flushing, localised rash. Must be stopped for major reactions, e.g. hypotension, dyspnoea, angioedema or generalised urticaria. Antihistamines, paracetamol and hydrocortisone can be used to treat reactions and should be available if required but must not be used prophylatically. If patient has hypersensitivity reaction follow manufacturers re-challenge guidelines before continuing with treatment. Units administering trastuzumab must have facilities available for the treatment of anaphylaxis and resuscitation. Patients who delay treatment for more than one week should be considered for reloading (8mg/kg) of trastuzumab. HCX-protocol-CRP10-UGI0101 v1.3 Page 3 of 6

4 EXTRAVASATION See NECN/ Local Policy TOXICITIES Herceptin is contraindicated in patients with severe dyspnoea at rest due to complications of advanced malignancy or requiring supplementary oxygen therapy. Risk of infusion reactions, hypersensitivity and anaphylaxis, particularly on first cycle. The majority of these events occur during or within 2.5 hours of the start of the first infusion. Pulmonary events, such as dyspnoea, bronchospasm, asthma and hypoxia. Adult Respiratory Distress Syndrome (ARDS) has been reported rarely with fatal outcome Cardiotoxicity - Do not give with anthracycline or give anthracycline within six months of patient receiving last dose of Herceptin. Chills and fevers common with first infusion Pain Myalgia, arthralgia Palmar/Plantar Erythrodysesthesia - Can be severe, patients must be forewarned Myelosuppression Nephrotoxicity due to cisplatin Nausea & Vomiting Diarrhoea Stomatitis Hyperpigmentation Alopecia Ototoxicity Neurotoxicity Metallic taste on administration Occasionally patients with heart disease may experience coronary artery spasm. DOSE MODIFICATION / TREATMENT DELAYS Haematological toxicity: Delay 1 week if WBC < 3.0, ANC < 1.5 and Platelets < 100. If ANC > 0.5 then the capecitabine may be continued at the same dose. Non-Haematological Toxicity for Oral Capecitabine Any patient with CTC toxicity should be prescribed the therapeutic option for grade 1 toxicity in addition to dose modification.
