The effect of laquinimod, a novel immuno-modulator in development to treat Huntington disease, on the pharmacokinetics of ethinylestradiol and levonorgestrel in healthy young women.
Trial report in European journal of clinical pharmacology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeLaquinimod is an orally dosed immuno-modulator currently under development for Huntington's disease (HD). Preclinical findings suggest potential teratogenicity of laquinimod, thus the reproductive ability of females with HD treated with laquinimod needs to be closely managed. Because combined oral contraceptives (COC) are often used in this context, the pharmacokinetics of COC containing ethinylestradiol (EE) and levonorgestrel (LNG) in combination with laquinimod (0.6 mg/day) was evaluated.
methodsIn this randomized, phase-1 single-center, double-blind, placebo-controlled, 2-way crossover drug-drug interaction (DDI) study in 48 healthy premenopausal women, COC were administered in a 28-day regimen of 21 days followed by 7 pill-free days for 4 cycles and laquinimod or placebo was administered for 28 days in cycle 1 and cycle 3 starting 7 days prior to COC administration. Blood samples for pharmacokinetic profiling of laquinimod, EE and LNG were collected on day 21 and day 22 of Cycles 1 and 3 pre-dose and multiple times post-dose.
resultsThe ratio of geometric means and 90% confidence intervals for AUC
conclusionThe combination of COC and laquinimod treatment was found to be safe, tolerable, and devoid of any noticeable pharmacokinetic interaction.
