This study aims to evaluate whether GSK3772701 alters the pharmacokinetics (PK) of midazolam (MDZ), a standard probe substrate for the CYP3A4 enzyme. The findings are planned to be used to determine whether GSK3772701 acts as an inducer and/or inhibitor of CYP3A4 and will help guide recommendations for safe co-administration with CYP3A4 substrates.
Aged 18 to 55 years (inclusive), at the time of signing the informed consent form (ICF).
Weight of at least 50 kg with a body-mass index <=18.0 and <=30.0 kg/m².
Written informed consent obtained from the participant prior to performance of any study specific procedure, and which includes agreement to compliance, with the requirements and restrictions listed in the ICF and in this protocol.
Participants, who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., completion of study assessments, return for follow-up visits).
History or presence/significant history of or current cardiovascular, respiratory, hepatic, renal, urological, gastrointestinal, immunological, dermatological, endocrine, hematologic, 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.
Any condition where the administration of MDZ could be contraindicated, including but not limited to, hypersensitivity (MDZ, any of its excipients, or to any benzodiazepines), sleep apnea, glaucoma (narrow-angle glaucoma, acute or open angle glaucoma, untreated), myasthenia gravis, respiratory insufficiency, impaired pulmonary function, or severe hepatic impairment.
History of any malignancy within the past 5 years. Exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy which is considered cured with minimal risk of recurrence. Participants under evaluation for possible malignancy are not eligible.
History of any reaction or hypersensitivity likely to be exacerbated by any component (formulation, capsule, or excipients) of the study intervention(s) (including hypromellose [hydroxypropyl methylcellulose] for GSK3772701) or allergies to cherries (as per MDZ USPI).
