Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 45 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • 45 to 65 years of age at the time of recruitment
  • Healthy -- see exclusion criteria
  • There is the possibility of at least a 20% absolute increase in the subject's energy subscale score of the Activation-Deactivation Adjective Checklist (AD ACL). For the purpose of meeting the inclusion criteria, the subject fills out the AD ACL with the following instructions: "Each of the words below describes feelings or moods. Please circle the rating next to each word that best describes your feelings during the past month. These instructions are different from the instructions used when the study endpoints are being measured so as to be consistent with the way the questionnaire was validated."

Who cannot join

  • Any major medical or mental illness (including a history of bipolar disorder, borderline personality disorder, and schizophrenia)
  • Medical diseases known to be associated with fatigue but not limited to:
  • AIDS
  • Anemia
  • Cancer or history of cancer (excluding basal cell carcinoma of the skin)
  • Chronic fatigue syndrome

  • Congestive heart failure
  • Chronic obstructive pulmonary disease (COPD)
  • Depression
  • Diabetes
  • Drug/alcohol dependence
  • Fibromyalgia
  • Hypertension that is uncontrolled or difficult to control
  • Hypothyroidism
  • Subjects taking the following medical therapies:
  • Beta-blocking medications
  • Human growth hormone
  • Testosterone
  • Warfarin
  • Subjects taking the following complementary and alternative medicine (CAM) products:
  • Feverfew
  • Garlic supplements
  • Ginseng
  • Red clover
  • Women who have not gone through menopause - those women who have had one or more menstrual periods in the 12 months prior to the enrollment in the study
  • The subject's score on the energy subscale of the AD ACL is at a level that precludes at least a 20% absolute increase of that score.
  • Subjects who are unable to make their own decisions regarding informed consent
  • Those subjects who have taken any of the medical therapies or CAM products listed but are no longer taking them are eligible to participate provided no other exclusion criteria are present and the subjects have not taken those therapies or products in the six months prior to enrollment.

About this study

Official title: The Effect of OPC Factor on Energy Levels in Healthy Individuals Aged 45-65: A Randomized Controlled Trial

In this study the food supplement OPC Factor will be tested to determine its effectiveness for increasing energy levels in healthy people aged 45-65 when compared to a placebo. All subjects will receive both active product and placebo at some time during the study. The study is nine weeks in duration. It involves three visits, taking an effervescent powder in water twice a day, and answering 24 multiple choice questions once a week. Subjects who complete the study can elect to receive a two month supply of the study product free of charge.

Read the detailed description

OPC Factor, a food supplement which contains grape seed extract, pine bark extract,vitamins and minerals, has shown during clinical observation the effect of raising energy levels in people aged 45-65. It is believed that the mechanism of action is based on enhanced production of ATP by mitochondria.

In this study subjects will be assigned by chance to either the active product group or the placebo group. Subjects will take the product for three weeks. Then there will be a two week wash out period followed by subjects being crossed over to the other group for a three week period. Subjects, assessors, and health providers will be masked as to who is in the active product group and who is in the placebo group. Subjects will meet with the primary investigator three times during the study, will fill out very short questions once a week, and receive phone calls once a week from study personnel.

This study is a randomized, placebo controlled, triple-blinded, cross-over study that tests the hypothesis that OPC Factor produces a response rate of 70% in the active product phase versus a 30% response rate during the placebo phase. A response is defined as at least a 20% absolute increase on the Energy subscale of the Activation-Deactivation Adjective Check List.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OPC Factor(TM)Dietary supplement

    Evervescent poweder containing oligomeric proanthocyanidins (OPCs)and other nutrients.

  • PlaceboOther

    Effervescent powder similar in taste and appearance to the intervention but without the OPCs and nutrients.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing OPC Factor(TM) in people with Healthy, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Energy subscore on the Activation-Deactivation Adjective Check List (time frame: Nine weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2011.
