Bioequivalence of a single dose of two palbociclib formulations in healthy Chinese subjects under fasting conditions: a two-period crossover study with rabeprazole pre-treatment.

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
Objectives: This study assessed the pharmacokinetics, safety, and bioequivalence of generic and original palbociclib tablets in healthy Chinese subjects under fasting conditions with rabeprazole pre-treatment. Methods: This was a single-dose, randomized, open-label, two-period crossover bioequivalence study conducted under fasting conditions with rabeprazole pre-treatment. In each trial, healthy Chinese subjects received 40 mg oral rabeprazole enteric-coated tablets once daily before breakfast for 6 days. Following an overnight fast of at least 10 h, they took the seventh dose of rabeprazole and maintained fasting. They then received a single 125 mg oral dose of either the test or reference palbociclib tablet, followed by a 14-day washout interval between periods. Blood samples were collected from 0 to 96 h post-dose in each period, and palbociclib plasma concentrations were determined using a validated method. The primary pharmacokinetic parameters were calculated using the non-compartmental method. The geometric mean ratios of the two formulations and the corresponding 90% confidence intervals were acquired for bioequivalence analysis. The safety of both formulations was also evaluated. Results: The 90% confidence intervals for the primary pharmacokinetic parameters of C Conclusion: The trial confirmed that the pharmacokinetic parameters of the generic and original palbociclib tablets were bioequivalent in healthy Chinese subjects under fasting conditions with rabeprazole pre-treatment. Both formulations were safe and well tolerated. Clinical Trial Registration: http://www.chinadrugtrials.org.cn, identifier CTR20232617; https://www.chictr.org.cn, identifier ChiCTR2400084355.
