Engineered T-cell and NK-cell therapies

Cell therapies attempt to provide persistent immune effectors that recognize conserved HIV targets, resist exhaustion or deliver antiviral molecules. Designs include expanded HIV-specific T cells, engineered receptors and NK-cell approaches.

Direction at a glance

Cell therapies attempt to provide persistent immune effectors that recognize conserved HIV targets, resist exhaustion or deliver antiviral molecules. Designs include expanded HIV-specific T cells, engineered receptors and NK-cell approaches.
Early clinicalCure and remissionPhase 1 safety and biologic-activity studies

What the evidence establishes

  • Small phase 1 studies can establish feasibility and short-term safety, not cure efficacy.
  • A 2025 open-label study evaluated autologous HIV-specific T cells in six adults.
  • A 2026 first-in-human study reported safety and biologic activity for a bispecific T-cell receptor targeting HIV Gag.

Next decisive research questions

01Can engineered cells reach lymph-node and gut reservoirs?
02How can persistence be improved without uncontrolled activation?
03Can off-the-shelf products replace bespoke manufacturing?
04Which combinations prevent viral escape?

Limits and responsible interpretation

What this direction does not yet prove

Current studies are small and early. Manufacturing, tissue access, antigen escape and safety monitoring limit near-term scale.

Development pathway

How this direction should be evaluated
DecisionRequired evidence
Biological activityTarget engagement and an outcome that cannot be explained by assay noise or selection.
Clinical valueMeaningful benefit, adequate follow-up, safety, comparison with current standard care and transparent uncertainty.
GeneralizabilityDiverse populations, subtypes, geographies, ages and clinically relevant comorbidities.
ScalabilityManufacturing, delivery, monitoring, price, workforce and community acceptability.
