3 Day 10 Posaconazole 300 mg Oral TWICE daily for 1 DAY, ONCE daily thereafter until 7 days after neutrophils recover to >0.5x10 9 /L (see supportive care section). This must not be started within 5 days of Mylotarg. Frequency & duration: See trial protocol for further details Notes: All patients who receive fludarabine should receive irradiated blood products throughout their chemotherapy and for life. The dose of in FLAG-Ida should be reduced to 1gm/m 2 on days 2-6 for patients 60+years of age in both course 1 and 2. Omit Day 1 G-CSF if WBC>30x10 9 /L, (Clinical decision, Dr Amott 2016) Patients with Serum Alanine Aminotransferase (AST) or Aspartate Aminotransferase (ALT) more than 2.5 times the local upper limit of normal (ULN) or bilirubin more than twice the ULN are not eligible for Gemtuzumab randomisations. Patients allocated to receive Gemtuzumab must not have a WBC count greater than 30 x 10 9 /L at the time of Gemtuzumab administration because of the risk of tumour lysis. Such patients should either have the WBC reduced with Hydroxycarbamide before commencing trial chemotherapy or have the administration of gemtuzumab delayed until day 4 of the chemotherapy. Patients should receive AmBisome 100mg intravenous infusion 3 times a week for antifungal cover, (Clinical decision, Dr Amott 2016). o A test dose of 1ml (1mg) intravenous infusion in dextrose 5% should be given over 10 minutes then stopped (infusion must be protected from light). o If no reaction occurs after 30 minutes the infusion can be restarted and given over 30 minutes. o AmBisome is not compatible with sodium chloride 0.9% - the line should be flushed with dextrose 5% after administration. If AmBisome is given on the same day as Gemtuzumab Ozogamicin, administer the AmBisome first. If this is not possible or other IV infusions in sodium chloride 0.9% have already been given, flush the line with dextrose 5% before AmBisome administration. PAGE 3 of 7

4 National dose banding tables have been approved for use by the Trial for nimp s. Baseline investigations 1. All patients should have their creatinine clearance measured using a 24 hour urine collection prior to each cycle (see below for dose modifications in case of renal impairment). The EGFR must not be used to assess renal function. If the creatinine is significantly increased in subsequent cycles renal function should be reassessed. modifications and toxicities 1. Renal impairment Patients with creatinine clearance <30 ml/min should be considered for alternative chemotherapy. Fludarabine Creatinine clearance ml/min >70 100% normal dose % normal dose <30 Use alternative regimen No reductions are necessary for renal impairment. Idarubicin Creatinine micromol/l <99 100% normal dose % normal dose >175 Clinical decision - consider alternative regime Gemtuzumab Ozogamicin (Mylotarg ) This is contraindicated if the renal function is abnormal. The Serum creatinine should be 1.5 upper limit of normal (ULN). PAGE 4 of 7

5 2. Hepatic impairment Fludarabine - no reductions are necessary for hepatic impairment. Bilirubin micromol/l <34 100% normal dose >34 50% normal dose Idarubicin Bilirubin micromol/l <21 100% normal dose % normal dose >34 Omit Gemtuzumab ozogamicin (Mylotarg ) This is contraindicated if liver function tests are abnormal. Patients must have Serum Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) 2.5 ULN and bilirubin 2.0 ULN. 3. Other toxicities A Cytosar syndrome has been described with use of. It is characterised by fever, myalgia, bone pain, occasional chest pains, maculopapular rash, conjunctivitis and malaise. This usually occurs 6-12 hours following infusion, and is more common with higher doses. Systemic steroids have been beneficial in treating this condition if severe. Gemtuzumab Ozogamicin (Mylotarg ) Premedication, consisting of an antihistamine (such as chlorphenamine) and paracetamol, should be given before each infusion to reduce the incidence of a post-infusion symptom complex. A steroid is not required unless a reaction occurs, in which case dexamethasone 8mg may be used prior to gemtuzumab on the next course. Vital signs should be monitored during infusion and for four hours following infusion. 0.2micron end-line filter used within the Trust is the Baxter Millipore IV Express which is held in stock on chemotherapy suite and ward 302.

6 Supportive care 1. Allopurinol 300mg once daily (Reduce dose to 100mg if GFR < 10ml/min) if there is risk of tumour lysis syndrome. Consider rasburicase if there is high risk of tumour lysis. The dose may need to be repeated for several days. 2. Ambisone 100mg three times a week given prophylactically prior to starting posaconazole. Ensure test dose is given on day 1 as anaphylaxis and anaphylactoid reactions have been reported in association with AmBisome infusion. Allergic type reactions, including severe infusion-related reactions can also occur. Although infusion-related reactions are not usually serious, consideration of precautionary measures for the prevention or treatment of these reactions should be given to patients who receive AmBisome therapy. Slower infusion rates (over 2 hours) or routine doses of chlorphenamine, paracetamol, pethidine and/or hydrocortisone have been reported as successful in their prevention or treatment. 3. Posaconazole 300mg orally TWICE daily for 1 day, 300mg ONCE daily thereafter. Continue for 7 days after neutrophils recover to >0.5x10 9 /L. If a patient is already on posaconazole when Mylotarg commences, stop the posaconazole & monitor liver function tests. Ideally posaconazole should not be given until at least day 5 after the administration of gemtuzumab ozogamicin (Mylotarg ). Note: Tablets and suspension are NOT interchangeable. The dose of suspension is 200mg three times a day, and must be taken during or immediately after a meal. The preferred option is posaconazole 100mg tablets as they achieve better plasma levels than the suspension. Monitoring of levels is not necessary in patients taking tablets unless there are concerns about absorption e.g. vomiting and diarrhoea, concomitant medication which may significantly affect the levels or the patient weighs >120kg. Due to erratic absorption of posaconazole from the suspension formulation, levels should be checked to ensure they have reached a therapeutic level. For more information on the use of posaconazole please refer to Antifungal treatment - haematology oncology - clinical guideline, BNF & Summary of Product Characteristics for posaconazole. 4. Prednisolone (0.5% Predsol) eye drops (or equivalent) should be used four times a day during the courses of high dose cytarabine and be continued for 5 days after each course finishes. PAGE 6 of 7
