E.1.1 | Medical condition(s) being investigated |
Breast cancer survivors on adjuvant treatment with an aromatase inhibitor having joint pain |
|
E.1.1.1 | Medical condition in easily understood language |
Breast cancer survivors with joint pain on treatment with an aromatase inhibitor to reduce their risk for breast cancer relapse |
|

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 try the hypothesis that vitamin D supplementation reduce joint pain in breast cancer survivors on adjuvant treatment with an aromatase inhibitor |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives is to try the hypothesis that vitamin D supplementation in breast cancer survivors on adjuvant treatment with an aromatase inhibitor reduce fatigue and depression and improve quality of life. The effect on the vitamin D levels in serum after 12 weeks of treatment will also be studied.
The safety objective is to verify that the use of vitamin D is safe and tolerable. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Breast cancer survivors at the Breastcentre, St Gorans Hospital on adjuvant endocrine treatment with an aromatase inhibitor having joint pain 2. The patient should have no cognitive failure, being able to comprehend oral and written information about the study. 3. 25 OHD < 50 nmol/L. 4. Women aged ≥18. 5. Signed 'informed consent'. |
|
E.4 | Principal exclusion criteria |
1. Ongoing vitamin D or calcium supplementation at the time for inclusion. 2. Serum level of 25-OH vitamin D3 >/= 50 nmol/L. 3. Known sarkoidosis. 4. Treament with tizzies. 5. Primary hyperparathyroidism. 6. Hypercalcaemia (verified by a laboratory result younger than 2 month). 7. History of kidney stones. 8. Hypersensivity to cholecalciferol and/or any of the excipients. 9. Other criteria that could jeopardize the study or its intention as judged by the investigator. 10. Not being able to perform EORTC-QLQ-BR23 or Brief Pain Inventory Short Form. |

E.5 End points |
E.5.1 | Primary end point(s) |
Reduced joint and muscle pain during 12 weeks of vitamin D supplementation |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Measurement of joint and muscle pain with Brief Pain Inventory Short Form at inclusion and after 6 and 12 weeks. |
|
E.5.2 | Secondary end point(s) |
1. Improvement in quality of life measured with EORTC-QLQ-BR23 at screening and after 6 and 12 weeks 2. Improvement in fatigue and depression measured with patient reported Numeric score 0-10 at screening and after 6 and 12 weeks 3. Levels of 25-OHD in serum after 12 weeks of treatment. 4. The safety endpoint is the frequency of AE among all subjects and the levels of calcium in plasma and urine (selected patients) during the study period. |
