Use of synthetic vectors for neutralising antibody resistant delivery of replicating adenovirus DNA.

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.
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
Use of synthetic vectors to deliver genomes of conditionally replicating lytic viruses combines the strengths of viral and non-viral approaches by enabling neutralising antibody resistant deployment of cancer virotherapy. Adenovirus is particularly suitable for this application since all proteins essential for replication can be expressed from the input DNA, although the presence of terminal protein (TP) covalently linked to the 5' termini of the input virus genomes both improves expression of transgenes encoded in the input DNA and also enhances replication. These roles of TP were distinguished in experiments where E1-deleted Ad(GFP)DNA bearing TP (Ad(GFP)DNA-TP), delivered with DOTAP, gave a two-fold greater frequency of transduction than Ad(GFP)DNA(without TP) in non-complementing A549 cells, while in 293 cells (which support replication of E1-deleted viruses) the presence of TP mediated a much greater differential transgene expression, commensurate with its ability to promote replication. Subsequent studies using AdDNA for virotherapy, therefore, included covalently linked TP. AdDNA-TP delivered to A549 cells using a synthetic polyplex vector was shown to be resistant to levels of neutralising antisera that completely ablated infection by wild-type adenovirus, enabling polyplex/Ad(wild type)DNA-TP to mediate a powerful cytopathic effect. Similarly in vivo, direct injection of a polyplex/Ad(wild type)DNA-TP into A549 tumours was neutralising antibody-resistant and enabled virus replication, whereas intact virus was neutralised by the antibody and failed to infect. The delivery of adenovirus genomes-TP using synthetic vectors should provide a strategy to bypass neutralising antibodies and facilitate clinical application of replicating adenovirus for cancer virotherapy.
