COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study design: This study is a double-blind, controlled, parallel arm (two arms) study
Arm 1: Commercially-available Apple and Boysenberry beverage (BerriQi)
Arm 2: Control beverage (Heat-treated version of BerriQi; depleted in anthocyanins)

Intervention details:
Dose: 30 mL of BerriQi or Control beverage, daily for 4 weeks (28 days)
Duration: 6 weeks
(I) a 2-week lead in period for screening, recruitment and randomisation, followed by
(II) a 4-week intervention period

Mode of administration: Oral (beverage form)

Important notes:
1. Participants can maintain their dietary habits throughout the 4 week intervention period. Participants are therefore allowed to consume other beverages throughout the intervention.
2. Participants will be provided with the beverage, free of charge, during the intervention period only.
3. At every visit, participants will be asked to return all used and unused bottles of the intervention products (BerriQi or control beverage). Adherence/compliance will be assessed by determining the proportion of unused bottles at each visit.
Intervention code [1] 316187 0
Treatment: Other
Comparator / control treatment
The main intervention beverage (arm 1) will consist of one serving (30 mL) of BerriQi® daily, for a total of 28 days.

The control beverage (arm 2) is the heat-treated version of the main intervention beverage (BerriQi). It has undergone heat inactivation to deplete its anthocyanins, which should render it inactive/less active relative to the main intervention. It is similar in all other physical and visual aspects to the main intervention beverage (i.e. BerriQi). Slight flavour and colour differences are externally unrecognisable to participants within this parallel arm study design. To blind all study coordinators and participants, the two products will be dispensed in two identical bottles with either a ‘black’ or ‘white’ label.

Placebo

Outcomes
Primary outcome [1] 322080 0
This study will evaluate the following primary outcome measures at baseline (day 0), mid-intervention (day 14) and at the end of the intervention (day 28):

Changes in lung function evaluated by spirometry as forced expiratory volume 1:forced vital capacity (FEV1/FVC) ratios.
(i.e. ratio of: the volume of air that has been exhaled at the end of the first second of forced expiration [FEV1] to forced vital capacity [FVC]).

This is a calculated ratio that measures how an individual inhales or exhales volumes of air as a function of time, and it provides an indicative clinical measure of how well an individual’s breathing capabilities are

Summary
Brief summary
The World Health Organization estimates that 90% of the world’s population is exposed to airborne particulate matter (PM), established drivers of systemic inflammation.
The purpose of this study is to investigate whether daily intake, as part of the habitual daily diet, for four weeks, of a New Zealand berry fruit product, made from natural boysenberries and apples, previously shown to benefit lung health in animal models of lung inflammation, can improve an aspect of lung health in adults living in an urban area in China (Nanjing, Jiangsu). Lung health will be assessed using spirometry, evaluated as the ratio of the volume of air that can be forced from the lungs in 1 second (Forced Expiratory Volume 1 or FEV1), divided by the total forced volume of the lungs (Forced Vital Capacity or FVC).
