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

This is an open-label, single-arm intra-patient dose escalating pilot study of ALT-803, a recombinant human super agonist interleukin-15 (IL-15) complex with an expansion cohort at the maximum tolerated dose (MTD). The primary aim is to investigate the safety and tolerability of ALT-803 in HIV-infected people receiving potent and optimized antiretroviral therapy. All infusions will occur on a Monday. Subjects will be monitored for 24 hours after the first infusion and then for 6 hours after each subsequent infusion, provided no unacceptable toxicity.

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

18 years to 99 years (ADULT, OLDER_ADULT)

Experimental: ALT-803
Drug: ALT-803

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.
Outcome Measure
Measure Description
Time Frame
Assess the safety and tolerability of ALT-803 in HIV-infected subjects
Time Frame: 4 weeks
Safety and tolerability is determined by the incidence of adverse events, size of the inducible reservoir as estimated using the TILDA assay
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assess the impact of ALT-803 on the size of the inducible reservoir,
Time Frame: 4 weeks
Assess the impact of ALT-803 on the size of the inducible reservoir, as estimated using the TILDA assay, in total CD4+ T cells and memory subsets
