- Allocation: RandomizedIntervention Model: Crossover AssignmentIntervention Model Description: Study will be conducted as Part A, B and C. Part A will consist of 2-interlocking cohorts, where each subject will receive maximum 2-single ascending oral doses of GSK3358699 and 1 dose of placebo, in Treatment Periods (TP) 1 to 3. In TP 4 subjects will receive GSK3358699, dose evaluated in TP (1 to 3) or placebo, with cantharidin induced blisters and either LPS or GM-CSF in vivo challenge. Part B will comprise of single cohort taking part in two-way cross over, with open label phase where each subject will receive single oral dose of GSK3358699 (based on Part A), under fed and fasted conditions in each TP. Part C will consist of 3 cohorts with multiple ascending doses, with every cohort having one repeat dose TP with 14 days of daily dosing of either GSK3358699 or placebo. Subjects on Day 14 will receive cantharidin induced blisters with either LPS or GM-CSF in vivo challenge. An optional, cohort 7 may be included for further dose evaluation of GSK3358699 or alternate dosing schedule.Masking: Double (Participant, Investigator)Masking Description: This will be a double blind (sponsor open) study with respect to allocation of GSK3358699 or placebo to subjects. All site staff will be blinded with the exception of un-blinded pharmacists. Investigators will be un-blinded with respect to the LPS and GM-CSF allocation. The food effect part of the study (Part B) will be open-labelPrimary Purpose: Treatment

Subjects who are enrolled in the dose escalation treatment Periods of Part A may choose to only take part in the dose escalation treatment Periods 1-3, or may choose to also take part in the challenge Treatment Period (Period 4). If a subject chooses to participate in the dose escalation treatment Periods 1-3 only, or does not (at screening) meet the eligibility criteria specific to challenges (treatment Period 4), a new subject will be recruited for treatment Period 4 only and will be regarded as a replacement subject. The study will be conducted in three Parts. Total duration for participation will be approximately 19 weeks for subjects taking part in all three dose escalation treatment Periods and 23 weeks if a subject takes part in all four treatment Periods of Part A. For replacement subjects only taking part in the challenge treatment Period (Period 4), approximate study duration will be 10 weeks. Total duration for participation will be approximately 9 weeks for Part B and 12 weeks for Part C. The study will be conducted in up to 80 subjects.
