Combined Treatment With Pembrolizumab and Allogenic BK Virus-Specific T Cells in Progressive Multifocal Leukoencephalopathy: A Case Report.
Article in Neurology(R) neuroimmunology & neuroinflammation, 2021. 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
objectiveWe report a combination of BK virus-specific T cells and pembrolizumab as a treatment option in progressive multifocal leukoencephalopathy (PML).
resultsA 57-year-old male patient diagnosed with PML presented a fast-progressing right hemiparesis, aphasia, and cognitive deficits. Brain MRI showed a severe leukoencephalopathy with diffusion restriction. The patient was treated with 10 doses of pembrolizumab (2 mg/kg body weight) in differing intervals and 2 partially human leukocyte antigen-matched allogenic BK virus-specific T cell transfusions after the fifth pembrolizumab treatment. Although pembrolizumab alone decreased the viral load but failed to control the virus, BK-specific T cell transfer further enhanced the decline of JC virus copies in the CSF. Moreover, the regression of leukoencephalopathy and disappearance of diffusion restriction in subsequent brain MRI were observed. The combined treatment resulted in a clinical stabilization with improvements of the cognitive and speech deficits. DISCUSSION: This case supports the hypothesis that pembrolizumab is more efficient in the presence of an appropriate number of functional antigen-specific T cells. Thus, the combined treatment of pembrolizumab and virus-specific T cells should be further evaluated as a treatment option for PML in future clinical trials.
