A Phase I Study to Evaluate the Safety and Toxicity of the Combination of Zidovudine and 2',3'-Dideoxyinosine (Didanosine) in Children With HIV Infection

October 31, 2012 updated by: National Cancer Institute (NCI)

To assess the safety and tolerance of the combination of zidovudine (AZT) and didanosine (ddI) in children with HIV infection.

New approaches to using available agents may provide increased or improved treatment options for AIDS. Combination therapy is expected to play a major role in improving survival and quality of life for HIV-infected individuals. AZT and ddI are two agents that have been most extensively evaluated and for which the evidence for antiretroviral effectiveness is strongest.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

New approaches to using available agents may provide increased or improved treatment options for AIDS. Combination therapy is expected to play a major role in improving survival and quality of life for HIV-infected individuals. AZT and ddI are two agents that have been most extensively evaluated and for which the evidence for antiretroviral effectiveness is strongest.

Patients take AZT and ddI on an empty stomach; ddI is taken 2 minutes after taking antacid. Part A patients receive AZT plus ddI each at ranging doses. Patients in part B may receive a higher dose of ddI than patients in part A. The first patients enrolled are given the lowest dose. Subsequent patients receive increasingly higher doses until a dose limiting toxicity occurs.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
85

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

3 months to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
