Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Osteoporosis is a growing problem worldwide, with the greatest burden resulting from fractures. Nevertheless, the majority of fractures in adults occur in those with "osteopenia" (bone mineral density (BMD) only moderately lower than young normal individuals) Since life long drug therapy is an expensive option with uncertain consequences and side effect, natural herbal therapy offers an attractive alternative. The classic Yin and Yang Tonic Formula (eg.Zuogui Pill, Yougui Pill) have been used for osteoporosis or osteopenia in traditional Chinese medicine(TCM) for a long time. For this reason, Chinese guidelines for the treatment of osteopenia include natural herbal therapy, however, there is currently no randomize placebo controlled trial to verify the efficacy for treating low BMD. This trial is randomized, double blind, placebo controlled design. Results of this study will provide evidence regarding the value of the classic Yin and Yang tonic formula as an intervention for increase BMD and decreasing fracture risk in osteopenia. Furthermore, the mechanisms of action can be identified by this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
