Trial summary

D-ribose, a natural occurring pentose carbohydrate, has repeatedly shown to enhance high-energy phosphates and improve function following ischemia, states of congestive heart failure, and recently in subjects with lung disease. Read more about this study

About this study

D-ribose, a natural occurring pentose carbohydrate, has repeatedly shown to enhance high-energy phosphates and improve function following ischemia, states of congestive heart failure, and recently in subjects with lung disease. An initial preliminary, open label pilot study demonstrated a positive benefit of D-ribose in "Baby-Boomer" subjects aged 50 to 65 years old complaining of persistent fatigue. The objective of this study will build on the previously collected data to evaluate oral D-ribose vs. dextrose (administered as a supplement) in relatively healthy, yet fatigued subjects with a goal of improving their state of fatigue.

What participants receive

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

  • D-riboseDietary supplement

    A 6 gm/day (3 gm/bid) dose of D-ribose in water. Each subject will consume oral D-ribose, dissolved in 8 fl. oz of water (1 serving) twice daily, for 2 weeks.

  • DextroseDietary supplement

    A 6 gm/day (3 gm/bid) dose of dextrose in water. Each subject will consume oral dextrose, dissolved in 8 fl. oz of water (1 serving) twice daily, for 2 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CPX parameters relative to placebo as measured by:

    Measured: Two weeks

  2. VO2 at AT

    Measured: Two weeks

  3. Ventilation Efficiency Slope

    Measured: Two weeks

  4. Oxygen Uptake Efficiency Slope

    Measured: Two weeks

  5. Heart rate to METS ratio at AT

    Measured: Two weeks

  6. Net Energy Expenditure at AT

Questions about this trial

What is this clinical trial studying?

A study testing D-ribose and Dextrose in people with Fatigue, run by Bioenergy Life Science, Inc. 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 7 inclusion and 19 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 7 Dec 2009. 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.

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?

CPX parameters relative to placebo as measured by: (time frame: Two weeks). The study lists 6 primary outcomes in all. 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 7 Dec 2009; AzTrials last refreshed its copy on 8 Nov 2026.
