Clinical Study of TUTI-16 in Asymptomatic HIV-1 Infected Subjects (THYMON-11001)

January 14, 2013 updated by: Thymon, LLC

Clinical Study of TUTI-16 in Asymptomatic, HIV-1 Infected Subjects Effectively Controlled by Antiretroviral Therapy and the Effects on Viral Load During a Structured Treatment Interruption

This protocol represents the third in human study of TUTI-16, and is being conducted to gather additional safety and human immunogenicity (anti-HIV-1 Tat titers) data of subcutaneously administered TUTI-16.

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

In this study, HIV-1 infected subjects on ART, with undetectable HIV-1 viral load, will be immunized with 1mg TUTI-16 or placebo in a randomized double blind fashion (prime and 3 week boost). Three weeks after the 3 week boost (week 6) ART will be stopped. HIV-1 viral load and CD4+ T-cell levels will be determined at defined intervals through 54 weeks (48 weeks Post ART discontinuation).

Study Type

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 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Males and Females
  • Age ≥ 18 and ≤ 50 years at Screening
  • Body weight of 50-100 kg (inclusive) at Screening.
  • HIV-1 seropositive subjects on effective ART for > 12 months (undetectable HIV plasma viremia), viral set point before ART > 10,000.
  • CD4+ T-cell count ≥ 500/mm3.
  • No antiviral drug within 8 weeks of screening. Patients stabilized on Aciclovir and Valciclovir for more than 6 months may be enrolled.
  • Karnofsky performance status > 90% at screening.
  • In good health as determined by medical history, a baseline physical examination, vital signs, and clinical laboratory tests.
  • Subject is willing and able to sign written informed consent prior to beginning study procedures.
  • Subject is willing and able to follow instructions, comply with the protocol requirements and make all required study visits.

Exclusion Criteria:

  • Females planning to become pregnant during the course of the study.
  • Females with a positive pregnancy test at Screening or study enrollment.
  • Any out-of range laboratory value at screening that has not been reviewed, approved and documented as not clinically significant by the Principal Investigator.
  • Systemic infection or other vaccination within 6 weeks prior to screening. Live vaccine within 1 year of screening.
  • Autoimmune disease (e.g., psoriasis, rheumatoid arthritis, etc.) or inflammatory bowel disease confirmed by clinical history.
  • Positive at screen for HBV (by HBsAg assay) or HCV (by antibody ELISA) unless there is no active infection as judged by an elevated alanine aminotransferase (ALT) at screening.
  • Alanine aminotransferase (ALT) above the upper limit of normal at screening.
  • Hemoglobin outside of laboratory normal range at screening.
  • Absolute neutrophil counts outside of laboratory normal range at screening.
  • Platelet count outside of laboratory normal range at screening.
  • A history of significant drug allergy.
  • A general medical or psychological condition or behavior, including current substance dependence or abuse that, in the opinion of the investigator, might not permit the subject to complete the study or sign the informed consent.
  • Subjects experiencing an acute Herpetic event.
  • Any other condition or clinically significant abnormal findings on the physical examination, medical history, or clinical laboratory results during screening that, in the opinion of the Principal Investigator would make the subject unsuitable for the study or put them at additional risk.
  • Routine or PRN consumption of immune suppressive medications that the subject is unable or unwilling to discontinue during the study.
  • Inability to understand or follow study instructions.
  • Participation in another investigational drug/vaccine study within 30 days preceding the first injection of investigational agent in this study.
