Engineered T-Cells take on HIV in early trial

NCT ID NCT03617198

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This early-stage study tests a new approach to HIV treatment. Researchers take a person's own T-cells, modify them to better recognize and attack HIV, and infuse them back. The main goal is to check safety in 12 stable HIV patients, while also seeing if the modified cells can help control the virus.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
genetically modified T-cells (CD4 CAR+CCR5 ZFN T-cells)
What this could lead to
If successful, this could point toward a way to control HIV without daily medication, by training the immune system to attack infected cells.
What could go wrong
This is a very early, small safety trial with only 12 people. The modified cells may not work as hoped, and there are risks of side effects from the cell infusion.

Inclusion Criteria: * HIV-1 infection * Clinically stable on first or second HAART regimen * Screening CD4+ T cell count of ≥450 cells/mm3 within 30 days of enrollment; and a documented CD4 nadir of not lower than 200 cells/mm3 * Screening HIV-1 RNA that is ≤50 copies/mL within 30 days prior to enrollment * HIV-1 RNA ≤50 copies/mL for at least 24 weeks prior to enrollment * Adequate venous access and no other contraindications for leukapheresis * Laboratory values within certain parameters, obtained within 30 days prior to enrollment * Willing to comply with study-mandated evaluations * Male or female, 18 years of age or older * Ability and willingness to provide informed consent * Karnofsky Performance Score of 70 or higher * Negative HBsAg (hepatitis B) within 6 months prior to enrollment * Negative HCV (hepatitis C) serology, or if positive, negative HCV RNA within 6 months prior to enrollment * Have a recorded viral load set point prior to starting antiretroviral therapy Exclusion Criteria: * Acute or chronic hepatitis B or hepatitis C infection * Current or prior AIDS diagnosis * History of cancer or malignancy, with the exception of successfully treated basal cell or squamous cell carcinoma of the skin * History or any features on physical examination indicative of active or unstable cardiac disease or hemodynamic instability (subjects with a history of cardiac disease may participate with a physician's approval) * History or any features of physical examination indicative of bleeding diathesis * Have been previously treated with any HIV experimental vaccine within 6 months prior to screening, or any previous gene therapy using an integrating vector (subjects treated with placebo in an HIV vaccine study will not be excluded if documentation that they received placebo is provided) * Use of chronic systemic corticosteroids, hydroxyurea, or immunomodulating agents within 30 days prior to enrollment (recent or current use of inhaled steroids is not exclusionary) * Breast-feeding, pregnant, or unwilling to use acceptable methods of birth control * Anticipated use of aspirin, dipyridamole, warfarin, or any other medication that is likely to affect platelet function or other aspects of blood coagulation during the 2 week period prior to leukapheresis * Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements * Serious illness requiring systemic treatment and/or hospitalization within 30 days prior to the study screening visit * Receipt of vaccination within 30 days prior to study screening visit * Have an allergy to hypersensitivity to study product components (human serum albumin, DMSO and Dextran 40) * Currently taking a non-nucleoside reverse transcriptase inhibitor (NNRTI)
