Nanoparticulate Impurities Isolated from Pharmaceutical-Grade Sucrose Are a Potential Threat to Protein Stability.
Article in Pharmaceutical research, 2017. 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
purposeTo investigate the effect of nanoparticulate impurities (NPIs) isolated from pharmaceutical-grade sucrose, on the stability of monoclonal antibodies (mAbs).
methodsNPIs were purified from pharmaceutical-grade sucrose and spiked into trastuzumab, rituximab, infliximab, and cetuximab formulations. The stability of the mAbs as a function of storage time, temperature, and NPI concentration was assessed by visual inspection, flow-imaging microscopy, nanoparticle tracking analysis, size-exclusion chromatography, capillary isoelectric focusing, and intrinsic differential scanning fluorimetry.
resultsNPIs negatively affected the stability of all mAbs, albeit it to different extents. After spiking with NPIs, trastuzumab formulations showed high numbers of μm-sized particles and turbidity, rituximab and cetuximab formulations contained high numbers of nm-sized particles, while infliximab formed nm- and μm-sized particles, and showed turbidity. Low-molecular-weight species were observed for rituximab and infliximab, whereas high-molecular-weight species were detected for cetuximab. Whereas the stability of trastuzumab and infliximab formulations was affected directly after spiking NPIs, degradation of rituximab and cetuximab was observed only after 14 weeks at elevated temperatures. Moreover, the stability of rituximab and infliximab was affected by NPI concentrations that are potentially present in final drug products.
conclusionsThe presence of sucrose-derived NPIs in (bio-)pharmaceutical formulations may pose a threat to the stability of mAbs.
