Demonstration of Biological and Immunological Equivalence of a Generic Glatiramer Acetate.
Article in CNS & neurological disorders drug targets, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn April 2015, the US Food and Drug Administration approved the first generic glatiramer acetate, Glatopa® (M356), as fully substitutable for Copaxone® 20 mg/mL for relapsing forms of multiple sclerosis (MS). This approval was accomplished through an Abbreviated New Drug Application that demonstrated equivalence to Copaxone.
methodThis article will provide an overview of the methods used to establish the biological and immunological equivalence of the two glatiramer acetate products, including methods evaluating antigenpresenting cell (APC) biology, T-cell biology, and other immunomodulatory effects.
resultsIn vitro and in vivo experiments from multiple redundant orthogonal assays within four biological processes (aggregate biology, APC biology, T-cell biology, and B-cell biology) modulated by glatiramer acetate in MS established the biological and immunological equivalence of Glatopa and Copaxone and are described. The following were observed when comparing Glatopa and Copaxone in these experiments: equivalent delays in symptom onset and reductions in "disease" intensity in experimental autoimmune encephalomyelitis; equivalent dose-dependent increases in Glatopa- and Copaxone- induced monokine-induced interferon-gamma release from THP-1 cells; a shift to a T helper 2 phenotype resulting in the secretion of interleukin (IL)-4 and downregulation of IL-17 release; no differences in immunogenicity and the presence of equivalent "immunofingerprints" between both versions of glatiramer acetate; and no stimulation of histamine release with either glatiramer acetate in basophilic leukemia 2H3 cell lines.
conclusionIn summary, this comprehensive approach across different biological and immunological pathways modulated by glatiramer acetate consistently supported the biological and immunological equivalence of Glatopa and Copaxone.
