BCMA-directed mRNA CAR-T cell therapy for myasthenia gravis: exploratory biomarker analysis of a placebo-controlled phase 2b trial.
Trial report in Nature medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07391605 (A Randomized Double-Blind Placebo-Controlled Study to Evaluate Efficacy, Safety, and Tolerability of Descartes-08 in Patients With Dermatomyositis and Antisynthetase Syndrome), which is not on this map. Cited by 13 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.

Abstract
Chimeric antigen receptor (CAR)-T cell therapies have the potential to transform treatment of autoimmune disease by resetting the immune system. However, adoption of cell therapies in the autoimmune space is limited by hurdles such as inpatient administration, lymphodepletion and safety concerns around cytokine release syndrome and non-specific immunosuppression. RNA-based cell therapy has potential to address these limitations. Here we report prespecified exploratory analyses from a successful placebo-controlled, double-blind, randomized phase 2b trial in patients with generalized myasthenia gravis who received Descartes-08, an autologous, RNA-encoded anti-B cell maturation antigen (BCMA) CAR-T cell therapy. In 66.7% of patients (n = 10/15), transient targeting of BCMA with Descartes-08 administered in an outpatient setting without lymphodepletion resulted in durable clinical efficacy. Comparison of Descartes-08-treated (n ≤ 19) and placebo (n ≤ 15) cohorts by flow cytometry, serum profiling, multiplexing cytokine analysis and bulk/single-cell transcriptional analysis reveals a precision retuning of self-reactivity demonstrated by increased pro-immune function, decreased activity of BCMA
