About this study

To determine the safety, pharmacokinetics (blood levels), and effectiveness of didanosine (ddI) when administered both intravenously and orally. After the maximum tolerated dose (MTD) is determined, an appropriate dosage regimen will then be established for Phase II and Phase III trials.

Zidovudine (AZT) has produced the best clinical results in the drug therapy of AIDS to date, but it produces toxicity in approximately 50 percent of patients. Early data show that ddI possesses high antiviral activity and less toxicity than AZT. The most effective route and dose of ddI has yet to be determined.

Read the detailed description

Zidovudine (AZT) has produced the best clinical results in the drug therapy of AIDS to date, but it produces toxicity in approximately 50 percent of patients. Early data show that ddI possesses high antiviral activity and less toxicity than AZT. The most effective route and dose of ddI has yet to be determined.

Patients are given intravenous drug for 14 days with a 1 day washout period, then 76 weeks of oral medication. To expedite this safety study and still be able to maintain close monitoring of the patient's health, an overlapping dosing regimen is used. After 6 patients have been enrolled and at least 4 have completed 4 weeks of dosing without significant toxic effects, a second group of patients is started at the next dose level.

AMENDED: An alternative oral dosing formulation of ddI will be provided as a buffer powder blend packaged in sealed foil sachets in several strengths.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Didanosine in people with HIV Infections, 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 50 inclusion and 0 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 4 Nov 2021. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 NCT00000710, which also lists 9 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 4 Nov 2021.
