Plain English Summary
Background and study aims
Osteoarthritis (OA) is the most common type of arthritis and affects millions of people worldwide. It occurs when the protective cartilage on the end of bones wears away. The bones then rub against one another, causing stiffness, pain and a reduction in the range of movement. The knee is the most common joint to be affected by OA and in many sufferers, the pain prevents people from moving around leading to muscle weakness and disability. Those with OA of the knee often require medication to help control the pain. However, there are now alternatives to the traditional medication such as herbal medications containing natural ingredients that may help with the pain and discomfort. UP1306 is an herbal formulation consists of herbs found naturally growing in northern China, Australia and other tropical, warm-temperature regions. The aim of this study is to determine the effects of an herbal formulation (UP1306) on discomfort and overall function when taken by individuals with OA of the knee over 12 weeks.
Who can participate?
Adults aged 35 to 75 years old who have symptoms of knee pain.
What does the study involve?
Participants are asked to attend seven study visits. The first visit determines participant’s eligibility. At the second study visit, participants have their weight, height, blood and urine measured, have x-rays taken, take part in a six minute walk test and have a range of motion test. Participants are then randomly allocated participants to one of three groups. Those in the first group receive the herbal medication, those in the second group receive a placebo medication (a dummy) and those in the last group receive a similar medication to the herbal medication. Participants take the medication by mouth four times daily, two with their morning meal and two with their evening dinner. Participants are asked to keep a diary of their pain and discomfort levels. Participants attend five more follow up visits to assess their knee discomfort and function.
What are the possible benefits and risks of participating?
There are no direct benefits with participating. There are some risks involved with participating. Participants may feel discomfort when providing blood samples. There are risks of feeling faint, redness of the vein and bruising/bleeding at the needle puncture sight. There are risks of radiation exposure due to having an x-ray. There are also risks with the study product causing allergic reactions such as rashes or itching, or causing more serious problems such as trouble breathing or swallowing.

| Scientific title | The effects of Morus alba and Acacia catechu on quality of life and overall function in adults with osteoarthritis of the knee |
| Study hypothesis | Morus alba and Acacia catechu combined together will have a positive effect on quality of life in those adults with osteoarthritis |
| Ethics approval(s) | Asprire IRB, 02/14/2014, ref: Study ID UNI-OA-2014 |
| Condition | Healthy subjects with joint pain/discomfort, osteoarthritis |
| Intervention | Participants attend a baseline screening visit (visit one) that involves a medical history, medication review, urine test for pregnancy, anthropomorphic measures, and a physical examination. If participants are deemed as eligible, they are randomly allocated by a third party statistician to one of three treatments. The consulting statistician develops a randomization schedule and created a randomization log for use at the investigative site. The participants are allocated, in equal probability, to one of three product groups using a Block-6 randomization scheme. Each group of six consecutively-enrolled subjects are allocated among the three products with two participants to each product in random order. The three treatments are: Group 1: A Morus alba and Acacia catechu based nutritional product UP1306 Group 2: Placebo Group 3: Glucosamine + chondroitin Participants attend six study visits, each visit lasts around two hours. The second study visit includes monitoring for changes in health and medication, questionnaires about discomfort, blood and urine tests, weight, blood pressure and heart rates measurements. Participants also have x-rays done. Participants are provided a breakfast of a bagel, cream cheese and orange juice. Participants are asked to perform a knee range of motion test, as well as a six minute walk test to see how far they can walk in six minutes. At this visit they are provided the study product and given instructions on how to use it. They are instructed to take four capsules of their assigned group's study product daily, two with a morning meal and two with an evening meal. They are required to fast after midnight prior to the study visits. They are asked to refrain from consuming alcohol or exercising for the 24 hours prior to the study visits. They are asked to complete a discomfort diary every day for the first seven days of taking the study product and after visit three they are required to complete the discomfort diary once a week for the remainder of the study. The follow up visits (visits three, four, five, six and seven) includes monitoring for changes in health and medication, questionnaires about discomfort, blood and urine tests, weight, blood pressure and heart rates measurements. Participants are provided a breakfast of a bagel, cream cheese and orange juice. Participants are asked to perform a knee range of motion test. At visit five, six and seven they are asked to perform a six-minute walk test. At visit seven participants have a physical examination and provide blood and urine samples. The entire duration of the study is 12 weeks. |
| Intervention type | Supplement |
| Primary outcome measure | Effect of UP 1306 is measured using the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) pain sub-score at 12 weeks. |
| Secondary outcome measures | Acute effect of UP 1306 is measured using the Visual Analog Scale (VAS) discomfort ratings and the rescue medication use at 12 weeks. |
