Membrane-bound MMP-14 protease-activatable adeno-associated viral vectors for gene delivery to pancreatic tumors.
Article in Gene therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Adeno-associated virus' (AAV) relatively simple structure makes it accommodating for engineering into controllable delivery platforms. Cancer, such as pancreatic ductal adenocarcinoma (PDAC), are often characterized by upregulation of membrane-bound proteins, such as MMP-14, that propagate survival integrin signaling. In order to target tumors, we have engineered an MMP-14 protease-activatable AAV vector that responds to both membrane-bound and extracellularly active MMPs. This "provector" was generated by inserting a tetra-aspartic acid inactivating motif flanked by the MMP-14 cleavage sequence IPESLRAG into the capsid subunits. The MMP-14 provector shows lower background transduction than previously developed provectors, leading to a 9.5-fold increase in transduction ability. In a murine model of PDAC, the MMP-14 provector shows increased delivery to an allograft tumor. This proof-of-concept study illustrates the possibilities of membrane-bound protease-activatable gene therapies to target tumors.
