Study summary

This is a two parts study, a single ascending dose followed by 14-days repeat dosing. The single ascending dose part will assess two dose levels of GSK3923868 or placebo across two treatment periods 1 and 2 in a single cohort of participants with a washout period of a minimum of 5 days after each treatment periods. The repeat dose part will assess repeated one dose level of GSK3923868 or placebo in treatment period 3 with up to 14 days of follow up in the same cohort of participants. The duration of study participation for treatment period 1, 2 and 3 will be 6, 6 and up to 29 days (including follow up), respectively.

Individual participant data

Plan to share: Yes — IPD for this study will be made available via the Clinical Study Data Request site.

Supporting information: Study protocol, Statistical analysis plan, Informed consent form, Clinical study report

Time frame: IPD will be made available within 6 months of publishing the results of the primary endpoints, a key secondary endpoints and safety data of the study.

Access criteria: Access is provided after a research proposal is submitted and has received approval from the 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 can be granted, when justified, for up to another 12 months.
