Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Is 18 to 60 years of age, inclusive, at the time of signing the Informed Consent Form (ICF).
  • Healthy as determined by investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, vital sign measurements, and cardiac monitoring.
  • Has a body mass index (BMI) from 18.0 to less than (\<) 30.0 kilograms per square meter (kg/m\^2).

You may not qualify if:

  • Has a history or evidence of clinically significant hematologic, dermatologic, neurologic, pulmonary, immunologic or atopic (except seasonal allergies), or endocrine disease, or psychiatric disorder (such as psychosis, delusions, or schizophrenia), or other abnormality, that may impact the ability of the participant to participate or potentially confound the study results, or that, in the investigator's opinion, makes the participant unsuitable for the study.
  • Presence (within 6 months) or history of significant liver or gastrointestinal (GI) disease that would be expected to influence the absorption of drugs (i.e., a history of malabsorption, any surgical intervention known to impact absorption \[e.g., bariatric surgery or bowel resection\], or clinically significant esophageal reflux), or surgery that may affect bioavailability as judged by the investigator.

Data Sharing

IPD Sharing
Will share

Study Sponsor will assess requests from qualified researchers for anonymized individual patient-level data and related study documents. Data sharing is subject to certain criteria, conditions, and exceptions. For further information, refer to https://www.gsk-studyregister.com/gsk-patient-level-data-sharing-july2025.pdf

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR
Time Frame
Anonymized IPD will be made available within 6 months of publication of primary, key secondary and safety results for studies in product with approved indication(s) or terminated asset(s) across all indications.
Access Criteria
Anonymized IPD is shared with researchers whose proposals are approved by an Independent Review Panel and after a Data Sharing Agreement is in place. Access is provided for an initial period of 12 months but an extension may be granted, when justified, for up to 6 months.
