简要总结
The Nutramax test article is a nutritional supplement that contains several ingredients shown to potentially provide benefit to patients suffering from a painful and sometimes debilitating condition of the knee called "osteoarthritis."
This is a pilot study that is intended to determine whether results from a proprietary testing panel conducted on blood and urine samples will correlate with data from physical examination and validated surveys that measure participants' quality of life and physical capabilities.
详细描述
Osteoarthritis (OA) of the knee is a significant source of morbidity, especially in patients over the age of 40 and is associated with more than $90 billion in US health care costs annually. While a myriad of clinical interventions are available, the mainstays of OA therapy are the NSAIDs, a class of compounds with well documented side effects including death; the risks of which increase with patient age and chronic use. Assessing the effectiveness of OA treatment modalities is often complicated by a high placebo effect, making purely clinical assessment of outcomes difficult. It is therefore desirable to develop an objective assessment tool for both the diagnosis/staging of knee OA and patient response to interventional therapies.
Participants in this study will receive a formulation of the nutraceutical (test article). They will be asked to take 3 pills at once per day for 40-44 days. There will be either 4 or 5 study visits. If participants have been using certain medications or dietary supplements, they will be asked to return one week from the initial screening, making a total of 5 visits in the study. If they have not been using key medications or dietary supplements, then study activities will begin on the day of the initial screening and they will only have 4 study visits.
Participants will be asked to complete a series of questionnaires about their health, and have their blood drawn (15 mls or about 3 teaspoons), and provide a urine sample at 4 visits. In addition, at the first visit, we will collect information from participants' medical record and they will have a physical exam.

- •Male or female subjects of any race, aged 40 to 64 years
- •Subject has a BMI of 24 to 40 kg/m2
- •Subject has had pain in one or both knees for a minimum of 15 days within the 30 days prior to the start of the study.
- •Subject has had symptoms of knee pain for at least 6 months.
- •Subject has been diagnosed within the previous 30 days with moderate to severe knee osteoarthritis - based on attending physician's diagnosis from physical exam in conjunction with Kellgren-Lawrence X-ray grade of ≥ 2 (radiographs taken within previous 30 days must be available to the investigator, or be obtained at the screening visit).
- •Subject can walk.
- •Before study enrollment, subject routinely uses acetaminophen (at any dose) with a history of therapeutic benefit.
- •Subject has a visual analogue scale (VAS) score of ≥ 4 at the initial visit. Subject may continue taking acetaminophen at the screening but will not have taken additional analgesics for at least 48 hours prior to the initial visit.
- •Female subject abstains from sexual intercourse, is surgically sterile, post-menopausal, or agrees to use a FDA-approved method of birth control.
排除标准
- •Subject has any of the following medical conditions:
- •active heart disease - defined as currently under the care of a cardiologist
- •high blood pressure (≥ 140/90 mmHg)
- •renal or hepatic impairment/disease
- •Type I or II diabetes
- •Bipolar or major depressive disorder or a history of other psychiatric illness requiring hospitalization in the past 6 months.
- •Parkinson's disease
- •unstable thyroid disease
- •immune disorder (such as HIV/AIDS)
- •multiple sclerosis or any other autoimmune disorder
- •any arthritic condition, other than OA, affecting a joint other than the knee
- •acute septic arthritis
- •fibromyalgia or other chronic pain syndromes (OA in locations other than knee allowed)
- •gout and hyperuricemia
- •peptic ulcer disease and/or history of upper gastrointestinal bleeding
- •any medical condition deemed exclusionary by the Principal Investigator (PI)
- •Subject has a history of cancer (except localized skin cancer without metastases or in situ cervical cancer) within five years prior to screening.
- •Subject has had a significant injury to the target joint within the past 12 months.
- •Subject plans to have knee surgery in the next 2 months.
- •Subject has had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medication.
- •Subject has an allergy to avocados, soybeans, shellfish or any other ingredient in the test product.
- •Subject requires additional analgesic or a change from acetaminophen. (Subjects requiring acetaminophen dose adjustments may remain in the study and all such dose and/or schedule changes shall be recorded in the raw data and daily patient diary).
- •Subject is currently taking any medication or suffers from a medical condition, deemed to potentially interfere with the objectives of the study as determined by the PI.
- •Subject has a history of drug or alcohol abuse in the past 12 months.
