1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Viral vector-based gene therapies (GTx) have received significant attention in the recent years and the number of ongoing GTx clinical trials is increasing. A platform of choice for many of these studies is adeno-associated virus (AAV). All humans may be exposed to natural AAV infections and could mount an immune response against the virus. Consequently, there can be a high prevalence of pre-existing anti-AAV immunity. This presents a potential limitation for AAV-based GTx due to the potential for AAV-specific antibodies to reduce the efficacy of the GTx. Therefore, appropriate assessment of potential subjects enrolled in these studies should include evaluation for the presence and degree of anti-AAV immunity, including anti-AAV neutralizing antibodies (NAb). Recommendations for the development and validation of cell-based anti-AAV NAb detection methods, including considerations related to selection of appropriate cell line, surrogate vector/reporter gene, assay matrix and controls, and methodologies for calculating assay cut-point are discussed herein. General recommendations for the key assay validation parameters are provided as well as considerations for the development of NAb diagnostic tests. This manuscript is produced by a group of scientists involved in GTx therapeutic development representing various companies. It is our intent to provide recommendations and guidance to industrial and academic laboratories working on viral vector based GTx modalities with the goal of achieving a more consistent approach to anti-AAV NAb assessment.
