Clinical Trial Summary

The trial is an investigator-initiated, double-blind, randomized, placebo-controlled phase III study.

After the patient has receiving information about the study and after given written informed consent, the patient will be screened. All patients are randomized to receive standardized rose hip powder or matching placebo for 3 weeks followed by half the dose standardized rose hip (or placebo) for the remaining 12 weeks of the study.

The patient's medical history and demographic information will be recorded. The patient will then be asked questions in accordance to the study questionnaires, and they will also be asked to complete questionnaires regarding quality of life - and finally they be instructed on how to complete the diary.

Investigator or study nurse will take telephone contact with the subject after 3 and 6 weeks of treatment, subjects will be asked about how things are going and to remember to take the capsules and whether they have completed the diary.

The contact taken after 6 weeks by phone is mainly to guide the subject on how complete the questionnaires including VAS scales.

The last patient visit will take place after 12 weeks. Any side effects will be reported to and reviewed with HybenVital ApS in collaboration with medical experts.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	difference in the effect by using WOMAC-pain score.

Primary	difference in the effect by using WOMAC-ADL score	The effect of treatment within each of the two groups (Rose hip powder and placebo) measured by using the differences in WOMAC-ADL (Activities of Daily Living) scores at 3 months of treatment between active treatment and placebo group, and between baseline and 3 months.	12 weeks	Yes
Secondary	Quality of life	Effects on QoL (SF-12 questionnaire and diaries) after 6 weeks and 12 weeks treatment, both groups compared to baseline, and the effects in the active group compared with the placebo group on QoL (SF-12 questionnaire and diaries) after 6 weeks and 12 weeks treatment.	12 weeks	No
