Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1. 4mg daily oral dexamethasone for 3 days, starting immediately pre zoledronate infusion (3 days total)
Arm 2. 4mg daily oral dexamethasone for 2 days, starting immediately pre zoledronate infusion, and then 4mg oral dexamethasone on day 3 only if symptomatic (ie 2-3 days total)
Arm 3. 1g oral paracetamol four times per day for 3 days starting immediately pre-zoledronate infusion. (3 days total)
Adherence to all medications will be checked with a self-reported question on how many tablets were taken
Intervention code [1] 329939 0
Treatment: Drugs
Comparator / control treatment
Arm 4. 1g oral paracetamol up to four times per day for 3 days starting post infusion and only taken if symptomatic. Adherence to all medications will be checked with a self-reported question on how many tablets were taken. Note that there are 4 active treatment arms without a pre-specified "control" group.
Control group
Active

Outcomes
Primary outcome [1] 339849 0
Difference between groups in mean greatest temperature change from baseline
Timepoint [1] 339849 0
Temperature will be assessed at baseline (pre-infusion) and then three times daily for 3 days (day of infusion and 2 days post-infusion).
Secondary outcome [1] 441642 0
Between-group difference in change in mean symptom score from baseline for 4 major symptom clusters (headache, nausea, muscle or joint pain, and fever). This will be assesses as a composite endpoint of the symptom clusters.
Timepoint [1] 441642 0
Symptom questionnaire will be completed at baseline (pre-infusion) and daily for 3 days (day of infusion and 2 days post-infusion) and at 7 days
Secondary outcome [2] 441643 0
Between-group difference in change in mean symptom score from baseline for remaining symptoms listed in the symptom questionnaire (All symptoms in questionnaire are fever, joint pain, joint swelling, muscle aches/ pain, stomach pain, nausea or vomiting, diarrhoea, other gut or bowel symptoms, fatigue, headache, blocked/runny nose, red/painful eye, any other symptom) This will be assessed as a composite outcome.
Timepoint [2] 441643 0
Symptom questionnaire will be completed at baseline (pre-infusion) and daily for 3 days (day of infusion and 2 days post-infusion) and at 7 days.
Secondary outcome [3] 441644 0
Between-group differences in the proportions in each group with an increase in oral temperature following zoledronate (increase of at least 1°C above baseline and final temp > 37.5°C)
Timepoint [3] 441644 0
Temperature will be assessed at baseline (pre-infusion) and then three times daily for 3 days (day of infusion and 2 days post-infusion).
Secondary outcome [4] 441645 0
Between-group differences in proportions in each group with at least one acute phase response-related symptom
Timepoint [4] 441645 0
Symptom questionnaire will be completed at baseline (pre-infusion) and daily for 3 days (day of infusion and 2 days post-infusion) and at 7 days
Secondary outcome [5] 441646 0
Between-group differences in proportions in each group requiring rescue medication
Timepoint [5] 441646 0
Rescue medication questionnaire will be completed daily for 3 days (day of infusion and 2 days post-infusion) and at 7 days.
