Summary

This FTIH study, intends to identify the doses of GSK3358699, which are well tolerated by the subjects whilst delivering a robust pharmacodynamic (PD) response. This study will evaluate the safety, tolerability, pharmacokinetic (PK) and PD profile of single (in both fed and fasted states) and multiple ascending doses of GSK3358699 in healthy male subjects within a pre-defined and controlled pharmacodynamic and pharmacokinetic range for each cohort. It also intends to understand the effect of GSK3358699 on systemic markers of inflammation following low dose in vivo lipopolysaccharide (LPS) or Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) challenge and local inflammation in cantharidin-induced blisters. The study has been carefully designed to explore the in vivo biology of the target and the potential for the study drug to become a transformative medicine for subjects in multiple immuno-inflammatory disease indications.

Conditions

  • Arthritis, Rheumatoid

Interventions

DRUG

Placebo

Placebo will be administered as a matching oral solution or matching capsule to study drug GSK3358699, during Part A and C once daily

DRUG

GSK3358699

GSK3358699, will be administered from 1 mg to 45 mg as an oral solution (1 to 10 mg) or as a capsule (3 to 45 mg), in Part A, B and Part C once daily.

BIOLOGICAL

GM-CSF

The GM-CSF will be administered as an intravenous infusion to subjects as 60 microgram per meter\^2 in Part A (Day 1) and Part C (Day 14).This will be administered for 2 hours approximately, no later than 24 hours post -dose of the GSK3358699 or placebo in Part C

BIOLOGICAL

LPS

LPS will be administered as an intravenous injection to subjects not exceeding 0.75 nanogram per kilogram in Part A (Day 1) and Part C (Day 14). This will be administered no later than 24 hours post -dose of the GSK3358699 or placebo in Part C.

OTHER

Cantharidin

This will be applied as a topical application with 0.7% cantharidin liquid which will be diluted with acetone to 0.2%.
