Long Term Follow-Up Study of Human Immunodeficiency Virus Type 1 (HIV-1) Positive Patients Who Have Received OZ1 Gene Therapy as Part of a Clinical Trial

November 20, 2018 updated by: Janssen-Cilag Pty Ltd

A Long Term Follow-up Protocol to Evaluate the Safety and Survival of Autologous CD34+ Hematopoietic Progenitor Cells Transduced With an Anti-HIV-1 Ribozyme (OZ1) in Patients With HIV-1 Infection

The purpose of this Observational Study is long term follow-up of the Human Immunodeficiency Virus -1 (HIV-1) infected patients who have received a gene therapy product (anti-HIV-1 Ribozyme [OZ1]) as part of an earlier phase 2 trial. Patients are seen twice yearly until 5 years from initial infusion of study drug has elapsed and then yearly until withdrawal or study completion. The study will monitor for and record any ill effects from the gene therapy product to provide long term safety information.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

During an earlier phase 2 base trial (study # NCT00074997), HIV-1 infected patients received a gene therapy product (anti-HIV-1 Ribozyme [OZ1]). Gene therapy is an investigational treatment where genes are inserted into an individual's cells and tissues to treat a disease. The gene therapy OZ1 is thought to have anti-HIV-1 actions. This is an Observational Study to provide long term follow-up of those HIV-1 infected patients who received the gene therapy product (anti-HIV-1 Ribozyme [OZ1]) as part of the earlier study. Patients are seen twice yearly until 5 years from initial infusion of study drug has elapsed and then yearly until withdrawal or study completion. The study will monitor for and record any ill effects from the gene therapy product to provide long term safety information. Observational study - no investigational drug administered.

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

  • Child
  • Adult
  • Older Adult

Description

Inclusion Criteria:

  • All patients who were enrolled (between 18 and 45 years of age) in the base study "OTH/OZ1-INT-1" (NCT00074997) will be invited to participate in this long term follow-up study
  • Patients must have received the Final Cell Product infusion in base study "OTH/OZ1-INT-1"
  • Have signed Informed Consent Form

Exclusion Criteria:

  • All patients who were enrolled in the OTH/OZ1-INT-1 study and received the final cell product will be invited to participate in this long term follow-up study. After unblinding of the OTH/OZ1-INT-1 study, any patients in the placebo arm will be withdrawn from this protocol

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
Percentage of Participants With Clonal Expansion of Cells With a Predominant OZ1 Insertion Site
Time Frame: Approximately up to 15 years
Percentage of participants with clonal expansion of cells with a predominant OZ1 insertion site was reported. A predominant integration site was defined as an integration site which has a density of at least 50 percent (%) of the total signal detected by polymerase chain reaction (PCR), when the percentage of cells marked by vector was greater than (>)1% of the test cell population.
Approximately up to 15 years
Percentage of Participants With Insertional Oncogenesis
Time Frame: Approximately up to 15 years
Percentage of participants with insertional oncogenesis by clonal expansion of cells modified with OZ1/LNL6 were reported.
Approximately up to 15 years
Number of Participants With Quantitative Marking of Gene Transfer Product in Peripheral Blood Mononuclear Cells (PBMC) Over Time
Time Frame: Up to end of study (Approximately up to 15 years)
OZ1 and LNL6 marking analysis were performed by quantitative deoxyribonucleic acid-polymerase chain reaction (DNA-PCR). Number of participants in each of 3 categories for gene detection: Not Detected, Detected (1, 2 and 3 of the 3 triplicates of the sample were detected respectively [1/3 Detected, 2/3 Detected, 3/3 Detected]) and Detected (Quantifiable) were reported for marking of gene transfer product in PBMC.
Up to end of study (Approximately up to 15 years)
