Biocomparison of Three Formulations of the S1P1 Receptor Modulator Ponesimod in Healthy Subjects.
Trial report in Drugs in R&D, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundPonesimod is a potent selective sphingosine-1-phosphate receptor 1 (S1P1) modulator, which leads to a reduction in circulating lymphocytes, reflecting their sequestration within lymphoid organs. Modulation of the S1P1 receptor has been previously described to be an effective treatment of autoimmune diseases (e.g., multiple sclerosis).
objectivesThe aim of this study was to compare the relative bioavailability of two polymorphic forms of ponesimod in capsules (Form A versus Form C; Study 1) and the relative bioavailability of a capsule formulation and a tablet formulation (both polymorphic Form C; Study 2).
methodsTwo open-label, randomized, two-way crossover studies in healthy subjects were performed. In Study 1, 12 male subjects received a single dose of 20 mg of polymorphic Form A or Form C of ponesimod in a capsule. In Study 2, 14 male and female subjects (ratio 1:1) received a single dose of 40 mg of polymorphic Form C of ponesimod in either a capsule or a tablet formulation. Pharmacokinetic and safety variables (clinical laboratory test results, vital signs, and an electrocardiogram) were assessed.
resultsComparison of the exposure to ponesimod following administration of the formulations in Study 1 showed that the 90 % confidence intervals of the geometric mean ratios for the area under the curve from time zero to infinity (AUC0-inf), the area under the curve from time zero to the time of the last measurable concentration (AUC0-t), the terminal half-life (t ½), and the maximum plasma concentration (C max) were all within the 0.80-1.25 bioequivalence interval. In Study 2, more rapid absorption of ponesimod was observed from the tablet formulation than from the capsule formulation. There were no relevant differences in the safety and tolerability profiles between the different formulations.
conclusionThe two polymorphic forms of ponesimod and tablet versus capsule formulations were similar in terms of pharmacokinetics, safety, and tolerability.
