Summary

The primary purpose of this study is to assess the pharmacodynamic effect of single, oral doses of SRT2104 (250 mg, 500 mg, 1000 mg, 2000 mg) and prednisolone as measured by levels of ex vivo LPS-induced TNF-alpha production in whole blood of healthy adult subjects.

The secondary purposes of this study are to assess the pharmacodynamic effects of single, oral doses of SRT2104 (250 mg, 500 mg, 1000 mg, 2000 mg) and prednisolone (30mg) as measured by levels of IL-6, IL-8 and IL-1beta in whole blood of healthy adult subjects. In addition, plasma pharmacokinetics, safety and tolerability of SRT2104 following the administration of single, oral doses of SRT2104 (250 mg, 500 mg, 1000 mg, 2000 mg) in healthy adult subjects will also be assessed. As exploratory endpoints, transcriptomic profiles, biomarker exploration, and relationships between plasma SRT2104 levels and ex vivo LPS-induced TNF-alpha production may also be examined.

Conditions

  • Pulmonary Disease, Chronic Obstructive

Interventions

DRUG

Placebo

Matching placebo is supplied containing microcrystalline cellulose (Avicel PH 105). Placebo will be administered as eight matched capsules.

DRUG

0.25g SRT2104

SRT2104 will be supplied as hard gelatin capsules, with each containing 250 mg. The 0.25g SRT2104 treatment visit will be administered as one SRT2104 capsule with 7 placebo capsules. Dosing will take place during one of the 6 treatment visits.

DRUG

Prednisolone

During the last treatment period, subjects will receive 30 mg open-label prednisolone.

DRUG

0.5g SRT2104

SRT2104 will be supplied as hard gelatin capsules, with each containing 250 mg. The 0.5g SRT2104 treatment visit will be administered as two SRT2104 capsules with 6 placebo capsules. Dosing will take place during one of the 6 treatment visits.

DRUG

1g SRT2104

SRT2104 will be supplied as hard gelatin capsules, with each containing 250 mg. The 1g SRT2104 treatment visit will be administered as four SRT2104 capsules with four placebo capsules. Dosing will take place during one of the 6 treatment visits.

DRUG

2g SRT2104

SRT2104 will be supplied as hard gelatin capsules, with each containing 250 mg. The 2g SRT2104 treatment visit will be administered as eight SRT2104 capsules. Dosing will take place during one of the 6 treatment visits.
