In Vitro and In Vivo Efficacy of Self-Assembling RGD Peptide Amphiphiles for Targeted Delivery of Paclitaxel.
Article in Pharmaceutical research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeThe objective of this work was to compare the efficacy of self-assembling cyclic and linear RGD peptide amphiphiles as carriers for delivering paclitaxel to αvβ3 integrin overexpressing tumors.
methodsLinear (C18-ADA5-RGD) and cyclic (C18-ADA5-cRGDfK) peptide amphiphiles were synthesized and characterized for CMC, aggregation number and micelle stability using fluorescence spectroscopy methods. Size and morphology of micelles was studied using TEM. Fluorescence polarization and confocal microscopy assays were established to compare binding and internalization of micelles. The targeting efficacy was studied in A2058 cells using cytotoxicity assay as well as in vivo in melanoma xenograft mouse model.
resultsThe linear and cyclic RGD amphiphiles exhibited CMC of 25 and 8 μM, respectively, formed nano-sized spherical micelles and showed competitive binding to αvβ3 integrin protein. FITC-loaded RGD micelles rapidly internalized into A2058 melanoma cells. Paclitaxel-loaded RGD micelles exhibited higher cytotoxicity compared with free drug in A2058 cells in vitro as well as in vivo.
conclusionCyclic RGD micelles exhibited better targeting efficacy but were less effective compared to linear RGD micelles as drug delivery vehicle due to lower drug solubilization capacity and lesser kinetic stability. Results from the study proved the effectiveness of self-assembling low molecular weight RGD amphiphiles as carriers for targeted delivery of paclitaxel.
