Trial summary
Lyme disease is the most common tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. It may exist in a chronic form and be the result of: 1) active infection by B. Read more about this study

About this study
Lyme disease is the most common tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. It may exist in a chronic form and be the result of: 1) active infection by B. burgdorferi; 2) damage caused by the original infectious process; or 3) the presence of co-infection with another organism transmitted by Ixodes ticks. The purpose of this study is to determine the safety and effectiveness, for seropositive patients, of intensive antibiotic treatment in eliminating symptoms of Chronic Lyme Disease (CLD).
Read the detailed description
One hundred ninety-four (194) patients will be enrolled in this study. Each patient will be assigned to one of two groups and will be randomly selected to receive either antibiotic therapy or placebo; but, the assignment of medication will not be made known to the patient or administering doctor. Antibiotic or placebo will be given intravenously (IV) for 30 consecutive days and then orally for the next 60 consecutive days.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ceftriaxone and doxycycline in people with Lyme Disease, run by National Institute of Allergy and Infectious Diseases (NIAID) 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 8 inclusion and 11 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 27 Aug 2010. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001101, which also lists 4 linked publications.
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 27 Aug 2010.
