Description of intervention(s) / exposure
This is a multi-centre, open label randomised parallel arm trial to determine whether guideline driven (targeted) aetiology based antiemetic therapy is more effective than single agent therapy with haloperidol in patients with cancer and nausea not related to anticancer therapy.
Participants will be randomised to active treatment arms 1 or 2.

In each trial arm, the duration of each step is 24 hours and the overall duration of treatment is 72 hours (3 days) after administration of the first study antiemetic. The mode of administration will be a clinician decision based on patient characteristics.

Abbreviations: subcutaneous (sc), po (orally), bd (twice daily), iv (intravenously), tds (three dimes/day), qid (four times /day), Q4/6h (every 4/6 hours), prn (as required).

Rescue medication for all patients will be metoclopramide (10mg po, sc, iv, prn q4h). If this dose is already delivered in the standard treatment (Arm 1), haloperidol (0.5mg po, sc, prn to q6h) will be administered.

Patients will have access to laxatives according to clinician practice.

Arm 1 Clinical Practice Guideline (CPG) driven antiemetic therapy, given orally or parenterally (subcutaneous or intravenous), according to the presumed cause of nausea, using freely available Pharmaceutical Benefits Scheme (PBS) listed antiemetics, in a 3 step dose escalation schedule. The duration of each step is 24 hours. Overall duration of treatment is 72 hours.

Treatment drugs are prochlorperazine, haloperidol, dexamethasone, promethazine, metoclopramide, hyoscine butylbromide, ranitidine.

CPG dosing schedule and drug selection by cause: If there are multiple causes, the most likely cause is chosen from the following schedule. Note: sc drug delivery can be in a 24hr infusion, except for Dexamethasone which is not given as an infusion.

Dominant Cause A: Central/Chemoreceptive Trigger Zone (CTZ) stimulation
Step 1 Prochlorperazine 5mg tds po
or 25mg PR followed by 5mg tds po

Step 1 Metoclopramide 10mg qid po/sc/iv
Step 2 Metoclopramide 10mg qid po/sc/iv,
Haloperidol 1.5mg/24hrs po/sc
Step 3 Metoclopramide 10mg Q4h po/sc/iv,
Haloperidol 3mg/24hrs sc

Arm 2 Haloperidol, in a 3 step dose escalation schedule from 1mg/24 hours to 3mg/24 hours orally or parenterally (subcutaneously).

Participants with intolerable nausea despite maximum breakthrough doses can proceed to Study 2 prior to the next 24 hour assessment. Participants already on Step 3 should be considered for Study 2.

Treatment after the 72 hour trial period should be at the clinicians’ discretion if the patient does not continue to study 2.

For all study participants, secondary outcomes and collection of data for safety will occur until the end of 4 weeks after the primary endpoint, unless consent is withdrawn.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients under the care or shared care of the palliative care team and all potential participants attending clinic will be screened by the study nurse for their suitability to enter the study in consultation with the treating clinician and nursing staff. The study nurse will ask the clinician in charge for permission to approach potentially eligible participants. This referral will be recorded within both the Case Report Form (CRF) and the participant clinical file. After checking with the clinical team to make sure the person meets the broad criteria for consideration of eligibility, that the person has given explicit permission to be seen by a researcher, and is well enough to be approached, the study nurse will introduce themself to the person and explain the study. If participants are suitable for entry and prepared to consent to the study, they will undergo baseline assessments and assessment of eligibility criteria. On notification of a participant, the site co-ordinator will consult the central registry to obtain the next code available. The Principal Investigator will then chart and order the allocated medication according to the code. A screening log will be kept of all potentially eligible participants including the reasons for non-entry.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation schedules will be developed for each site using random numbers generated by computer at an independent centre. Treatment for each patient will be allocated according to a block randomisation schedule held by the central registry at the Queensland University of Technology. Site coordinators will contact the central registry to obtain random allocation once consent has been obtained. Block randomisation within the centre will ensure even allocation to each code in each site. Sites will not be informed of the block size in order to minimise bias in patient allocation.
