Gene study aims to personalize common heart drug
NCT ID NCT03051282
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how genetic differences affect the activation of enalapril, a common blood pressure medication. Researchers gave 21 healthy volunteers enalapril for a week and measured drug levels in their blood. The goal was to see if a specific gene variant (G143E) changes how the body processes the drug, which could lead to more personalized dosing in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- enalapril
- What this could lead to
- If successful, this could help doctors personalize ACE inhibitor dosing based on a person's genetics, improving effectiveness and reducing side effects.
- What could go wrong
- This is a small, early-stage study in healthy volunteers, not patients. Results may not translate to real-world treatment or account for other factors affecting drug response.

Inclusion Criteria: * Subjects must be male and female (50:50) between the ages of 18-55 years * Females must have a negative urine pregnancy test prior to the study * All subjects must have no clinically significant diseases or clinically significant abnormal laboratory values as assessed during the screening medical history, nursing assessment, and laboratory evaluations * Informed consent must be signed by the eligible subject prior to the initiation of any study procedures Exclusion Criteria: * The presence of a known medical condition that would preclude the use of enalapril * The presence of any surgical or medical condition (active or chronic) that may interfere with drug absorption, distribution, metabolism, or excretion. * A positive urine pregnancy test in the MCRU prior to the study * No subjects weighing under 50 kg will be selected * The lack of use of acceptable methods of birth control unless abstinent * Subjects who regularly take medications, vitamins, herbal supplements * The use of any illicit drugs or habitual consumption of large quantities of ethanol (\>3 drinks/day) * The consumption of grapefruit or grapefruit juice a week prior to, and during the study * Asians will not be included in the study as the CES1 SNP G143E is absent in this population * Subjects hypersensitive to enalapril * Subject with a history of angioedema * Smokers
