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.
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.

Percentage of Participants With Clonal Expansion of Cells With a Predominant OZ1 Insertion Site
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.
Time frame: Approximately up to 15 years
Percentage of Participants With Insertional Oncogenesis
Percentage of participants with insertional oncogenesis by clonal expansion of cells modified with OZ1/LNL6 were reported.
Time frame: Approximately up to 15 years
Number of Participants With Quantitative Marking of Gene Transfer Product in Peripheral Blood Mononuclear Cells (PBMC) Over Time
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.
Time frame: Up to end of study (Approximately up to 15 years)
