Bioequivalence of saxagliptin/metformin extended-release (XR) fixed-dose combination tablets and single-component saxagliptin and metformin XR tablets in healthy adult Chinese subjects.
Trial report in Clinical drug investigation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesAs compared with individual tablets, saxagliptin/metformin extended-release (XR) fixed-dose combination (FDC) tablets offer the potential for increased patient compliance with the convenience of once daily dosing. The aim of the present study was to show that the FDC of saxagliptin and metformin XR is bioequivalent to co-administration of the individual components when given to Chinese subjects residing in China.
methodsThis was a randomized, open-label, single-dose, two-period, cross-over pharmacokinetic study in two cohorts of healthy adult Chinese male subjects (n = 32 in each cohort) under fed conditions. In cohort 1, the pharmacokinetic properties of a saxagliptin/metformin XR 5/500 mg FDC tablet were compared with those of co-administration of a 5 mg saxagliptin tablet and a 500 mg metformin XR tablet. In cohort 2, the pharmacokinetic properties of a saxagliptin/metformin XR 5/1,000 mg FDC tablet were compared with those of co-administration of a 5 mg saxagliptin tablet and 2 × 500 mg metformin XR tablets. The two cohorts were independent of each other with respect to treatment and results. The pharmacokinetic properties of the active metabolite of saxagliptin (5-hydroxy-saxagliptin), as well as the safety and tolerability of each treatment, were also evaluated.
resultsFor both cohorts, saxagliptin and metformin in the FDCs were bioequivalent to the individual components, as the limits of the 90 % confidence intervals of the geometric least squares mean ratios were contained within the 80-125 % bioequivalence limits for the area under the plasma concentration-time curve parameters and within the 70-143 % bioequivalence limits for the maximum plasma concentration. Similar exposures of 5-hydroxy-saxagliptin were observed with the two treatment regimens within each cohort. Co-administration of saxagliptin and metformin XR was generally safe and well tolerated as the FDCs or as individual tablets.
conclusionSaxagliptin/metformin XR 5/500 mg and saxagliptin/metformin XR 5/1,000 mg FDCs were bioequivalent to individual tablets of saxagliptin and metformin XR of the same strengths and were generally well tolerated. These results in healthy Chinese subjects are consistent with those of previous assessments of saxagliptin/metformin XR FDC in the saxagliptin clinical development programme.
