Drug Interaction Assessment of GSK3882347 in Healthy Participants Aged 18 to 65 Years

Phase 1
Completed
Conditions
Urinary Tract Infections
Interventions
Registration Number
NCT05760261
Lead Sponsor
GlaxoSmithKline
Brief Summary

The objective of this study is to determine the magnitude and clinical relevance of a potential drug-drug interaction of GSK3882347 with midazolam (MDZ) in healthy participants. This study assesses the effect of GSK3882347 as an inducer of Cytochrome P450 3A4 (CYP3A4) using MDZ, a sensitive substrate of hepatic and intestinal CYP3A4. The study will investigate MDZ pharmacokinetic (PK) effect in two dosing periods:

Period 1: A single dose of MDZ Period 2: 14-days of once daily repeat dosing of GSK3882347 followed by single dose of MDZ co-administered with GSK3882347 on Day 15 (14-days has been selected as this duration is required in order to maximize any potential CYP3A4 enzyme induction).

Exclusion Criteria
  • History or presence of significant cardiovascular, respiratory, hepatic, renal, urological, gastrointestinal, metabolic, endocrinological, hematological, immunologic, dermatologic, neurological or psychiatric disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data or in the opinion of the investigator places the participants at unacceptable risk or would make adhering to study procedures for the duration of the study difficult. Participants who have had a gastric bypass or a cholecystectomy are excluded from the study.

  • Abnormal blood pressure, as determined by the investigator.

  • Alanine transferase (ALT) value greater than (>)1.5 × upper limit of normal (ULN).

  • Bilirubin value >1.5 × ULN (isolated bilirubin >1.5 × ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).

  • The participant has a current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).

  • The participant has congenital long QT syndrome or known prolongation of the corrected QT (QTc) interval.

  • The participant has any history of heart failure.

  • The participant has a family history of QT prolongation or sudden death.

  • The participant has any current or previous a history of episodes of symptomatic bradycardia or bradyarrhythmia.

  • The participant has a QTc >450 millisecond (msec). Note: The QTc is the QT interval corrected for heart rate according to Fridericia formula, machine, or manual overread.

    1. The participant has anuria, oliguria, or impairment of renal function (GFR by Modification of diet in renal disease [MDRD] <90 milliliter per minute per 1.73 meter square [mL/min/1.73m^2] or serum creatinine > ULN or urine albumin-creatinine ratio [ACR] of ≥300 milligram per gram [mg/g] at screening).
  • The participant must agree to and adhere to the concomitant therapy (including nondrug therapies) restrictions from the Screening Visit through to the end of the end of the study (including telephone visit).

  • Participation in the study would result in loss of blood or blood products in excess of 500 milliliter (mL) within 56 days.

  • Exposure to more than 4 new chemical entities within 12 months prior to the first dosing day.

  • Current enrolment or past participation within the last 30 days or 5 half-lives, whichever is longer, before signing of consent in any other clinical study involving an investigational study intervention or any other type of medical research.

  • Current enrolment or past participation in this clinical study.

  • Positive human immunodeficiency virus (HIV) antibody test.

  • Presence of Hepatitis B surface antigen (HbsAg) at screening or within 3 months prior to first dose of study intervention.

  • Hepatitis C antibody test result at screening or within 3 months prior to first dose of study intervention.

  • A positive confirmation of Coronavirus disease 2019 (COVID-19) infection, or high clinical index of suspicion for COVID-19.

  • The participant, in the judgment of the investigator, would not be able or willing to comply with the protocol or complete the study.

  • Regular alcohol consumption within 6 months prior to the study. An average weekly intake of >14 units for males or females. One unit is equivalent to approximately to 8 g of alcohol: a half-pint (approximately [~]240 mL) of beer, one glass (125 mL) of wine or one (25 mL) measure of spirits.

  • Positive smoke breathalyzer indicative of smoking history at screening and each in-house admission to the clinical research unit or regular use of tobacco or nicotine-containing products (i.e., nicotine patches or vaporizing devices) within 3 months prior to screening.

  • Regular use of combustible tobacco products, and non-combustible nicotine delivery systems, inclusive of cigarettes, cigars, pipes, and materials used to "vape".

  • Any history of substance abuse or a positive urine test for drugs of abuse/ alcohol breath screen at screening or admission.

  • Known hypersensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates participation in the study.

  • Contraindication for MDZ (i.e., Hypersensitivity to the active substance, benzodiazepines or to any of the excipients, myasthenia gravis, respiratory insufficiency, sleep apnea syndrome, severe hepatic impairment).

  • Use of any products intended to treat medical conditions that are not approved by the governing health authority in a given country or region (for example, herbal medicine, health supplements, traditional medicine, homeopathic remedies, etc.).
