E.1.1.1 | Medical condition in easily understood language |

MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to test the hypothesis vitamin D supplementation for 12 weeks reduces opioid consumption. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to test the hypothesis that vitamin D supplementation for 12 weeks leads to decline in antibiotic consumption, improvement in quality of life and improvement in fatigue. The effect on the vitamin D levels in serum after 12 weeks of treatment will also be studied. We will also investigate the change in opioid dose in relation to genetic polymorphism in genes involved in the effect and metabolism of vitamin D, VDR(TaqI and FoqI), GC (Rs2282679, CYP2R1 (Rs2060793), CYP27B (Rs10877012) and CYP24A1 (rs Rs6013897).
The safety objective is to verify that the use of vitamin D is safe and tolerable.

9. Taking part of another clinical study involving drugs.
10. Hypersensivity to cholecalciferol and/or any of the excipients.
11. Other criteria that could jeopardize the study or its intention as judged by the investigator.

E.5 End points |
E.5.1 | Primary end point(s) |
1) The decline of opioid-consumption during 12 weeks in the vitamin D group compared to the placebo groups, based on 4 measurements with 4 week intervals. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
1) Opioid dose, translated to fentanyl per hour measured at baseline and at week 4, 8 and 12.
|
|
E.5.2 | Secondary end point(s) |
1) Decline in antibiotic consumption (expressed as % of days with antibiotics during the last 4 weeks) based on measurements at baseline, week 4, 8 and 12.
2) Improvement in quality of life measured with EORTC-QLQ-PAL15 at screening and after 12 weeks
3) Improvement in fatigue measured with EORTC-QLQ-PAL15 at screening and after 12 weeks
4) Improvement in symptom burden measured with ESAS.
5) Levels of 25-OHD in serum after 12 weeks of treatment.
6) The change in opioid dose in relation to genetic polymorphism in genes involved in the effect and metabolism of vitamin D, VDR(TaqI and FoqI), GC (Rs2282679, CYP2R1 (Rs2060793), CYP27B (Rs10877012) and CYP24A1 (rs Rs6013897).
7) The safety endpoint is the frequency of AE among all subjects and the levels of calcium in plasma and urine (selected patients).
