Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study duration is 12 weeks; 2-week lead-in period for screening, recruitment, and baseline measurements, followed by a 4-week intervention period, a 2-week washout period, followed by another 4-week intervention period.

Participants will be recruited from sarcoidosis support e-groups. The aims of the study and investigational product will be described, along with descriptions of the questionnaires and the medical data sought, and information for their healthcare providers. It is expected that motivated support e-group members will volunteer to participate. Following emailed confirmation of participation, receipt of written informed consent and appropriateness of volunteered data, participants will be courier-posted to consume daily, for 4 weeks, either a 30 mL berry fruit beverage (BerriQi®) or a heat-inactivated version (placebo) and asked to continue to volunteer appropriate medical data from their usual medical monitoring regime. Participants will continue with their usual ongoing medical treatment. After 4 weeks, participants will have a 2 week washout period, followed by another 4-week intervention period where they will be sent to consume daily , either a 30 mL berry fruit beverage (BerriQi®) or a heat-inactivated version (placebo) and continue to volunteer medical data.

At baseline (Day 0), midpoint (Day 14) and endpoint (Day 28) of each intervention, participants will complete questionnaires to assess their dietary habits as a means of ensuring compliance and to remind them to avoid berry-based foods, and at the beginning (Day 0) and end (Day 28) of each intervention to assess their lung health.

Participants will provide lung function and liver function tests, obtained from their healthcare provider at the beginning (Day 0) and end (Day 28) of each intervention as a part of the routine monitoring of their condition. These results will be sent by email.

This study will be conducted entirely online with investigational product and placebo sent by mail. Used and unused bottles will be returned by mail to check compliance.

Comparator / control treatment
This is a randomised placebo controlled crossover study. Participants will be randomised to recieve and drink either 30 mL BerriQi fruit drink or 30 mL heat-inactivated BerriQi (experimentally determined in preclinical studies to not provide benefits observed with active BerriQi) daily for 28 days for the first intervention period, and after a 2 week washout period, the opposite (heat-inactivated placebo or active BerriQi) treatment in the second intervention period.

Participants will continue to recieve their normal medical treatment.
Control group
Placebo

Efficacy
Statistical methods / analysis
Lung function is the primary end point of this study. We were unable to find qualitative data for sarcoidosis studies using the SGRQ to allow a power analysis based on the so-called clinically significant improvement in 4/100. Instead we have calculated power on the basis of FVC improvements in sarcoidosis patients responding to infliximab (Baughman et al., 2006). This study allowed for treatment sample sizes of n=40 with a statistical power of 80% to detect a 10% improvement in FVC. Erring on the side of caution and allowing for larger drop out (incompletion) rates due to the hands-off online crowdsource nature of this study, we figure 55 participants will provide adequate power to establish differences in all end points.

Summary
Brief summary
The aims of this study are to determine whether a 4-week, daily supplementation of a New Zealand berry fruit supplement product (BerriQi®) can improve lung function in free-living adults with pulmonary sarcoidosis over baseline (day 0) values. We hypothesise that BerriQi® consumption can improve breathing parameters as measured by spirometry and also result in improved serum ACE and blood liver function tests. This is a randomised crossover placebo-controlled double blind study.
