Abstract

In a clinical trial for adeno-associated virus serotype 1 (AAV-1)–mediated gene transfer to muscle for lipoprotein lipase (LPL) deficiency, 1 subject from the high-dose cohort experienced a transient increase in the muscle enzyme creatine phosphokinase (CPK) 4 weeks after gene transfer. Simultaneously, after an initial downward trend consistent with expression of LPL, plasma triglyceride levels returned to baseline. We characterized B- and T-cell responses to the vector and the transgene product in the subjects enrolled in this study. IFN-γ enzyme-linked immunosorbent spot (ELISpot) and intracellular cytokine staining assays performed on peripheral blood mononuclear cells (PBMCs) from the subject who experienced the CPK elevation showed the activation of capsid-specific CD4+ and CD8+ T cells. Four of 8 subjects had detectable T-cell responses to capsid with dose-dependent kinetics of appearance. Subjects with detectable T-cell responses to capsid also had higher anti–AAV-1 IgG3 antibody titer. No subject developed B- or T-cell responses to the LPL transgene product. These findings suggest that T-cell responses directed to the AAV-1 capsid are dose-dependent. Whether they also limit the duration of expression of the transgene at higher doses is unclear, and will require additional analyses at later time points.

  • In patients receiving intramuscular AAV1 gene therapy with alipogene tiparvovec for lipoprotein lipase deficiency, dose-dependent AAV-specific T cell activation was seen.

    “For example, dose-dependent, AAV-specific T cell activation was seen in patients who received intramuscular gene therapy with an AAV1 vector (alipogene tiparvovec, Glybera) for lipoprotein lipase deficiency (Mingozzi et al., 2009; Ferreira et al., 2014).”

    From Gene Therapy-Associated Uveitis (GTAU): Understanding and mitigating the adverse immune response in retinal gene therapy (2025) · cites this paper as Mingozzi et al., 2009

    The Introduction (p. 1) describes intramuscular AAV-1 gene transfer for lipoprotein lipase deficiency, and the results (p. 3) report capsid-specific T-cell responses in 4 of 8 subjects with dose-dependent timing. Our copy identifies the vector as AAV-1–LPL S447X but does not identify it as alipogene tiparvovec or Glybera, so that part of the attribution is not verified. (LLM, conf=0.85)

  • The capsid-specific immune response is dose-dependent and administration of low vector doses of AAV are more likely to induce mild inflammation that is manageable by steroids.

    “Further studies confirmed that the capsid-specific immune response is dose-dependent and administration of low vector doses of AAV are more likely to induce mild inflammation that is manageable by steroids [86–88].”
  • Other trials have observed T-cell immune responses that did not clear transgene expression, particularly muscle-directed trials.

    “In contrast, other trials have observed T-cell immune responses that did not clear transgene expression, particularly muscle-directed trials [86, 90, 91].”
  • Concurrent clinical trials using i.m. delivery of AAV revealed long-term transgene expression without immune suppression, regardless of significant immune cell infiltration.

    “Despite the observation of immune responses after intravenous (i.v.) administration of AAV, concurrent clinical trials using intramuscular (i.m.) delivery of AAV revealed long-term transgene expression without immune suppression, regardless of significant immune cell infiltration.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
