Pharmacogenetics of plasma dolutegravir exposure during 1-month rifapentine/isoniazid treatment of latent tuberculosis.
Article in Pharmacogenetics and genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In Advancing Clinical Therapeutics Globally protocol A5372, a pharmacokinetic study of dolutegravir with 1-month of daily rifapentine/isoniazid, twice-daily dolutegravir offset the induction effects of rifapentine on plasma dolutegravir trough concentrations (C trough ). Here, we characterize the impact on dolutegravir C trough of UGT1A1 , AADAC , and NAT2 polymorphisms that affect dolutegravir, rifapentine, and isoniazid, respectively. People with HIV receiving dolutegravir-based antiretroviral therapy with an indication to treat latent tuberculosis underwent pharmacokinetic sampling during dolutegravir 50 mg once daily alone, and on day 28 of dolutegravir 50 mg twice daily with rifapentine/isoniazid. Multivariable linear regression models characterized genetic associations with dolutegravir C trough . Among 30 participants evaluable for genetic associations, median (Q1, Q3) day 0 dolutegravir C trough was 1745 (1099, 2694) ng/ml, and day 28 was 2146 (1412, 2484) ng/ml. Day 28 C trough was higher with UGT1A1 rs887829 TT [geometric mean ratio (GMR) = 1.65; 90% confidence interval (CI): 0.97-2.78] and CT (GMR = 1.38; 90% CI: 1.02-1.86) than with CC, and was higher with AADAC rs1803155 GG (GMR = 1.79; 90% CI: 1.09-2.93) and AG (GMR = 1.48; 90% CI: 1.14-1.90) than with AA. Median day 28 C trough ranged from 1205 (1063, 1897) ng/ml with 4 total UGT1A1 and AADAC risk alleles, to 3882 and 3717 ng/ml with only one risk allele. Individuals with concomitant AADAC slow metabolizer and UGT1A1 normal metabolizer genotypes may be at greater risk for clinically significant drug-drug interactions between rifapentine/isoniazid and dolutegravir.
