Raynaud’s phenomenon
Conditions
Brief summary
For each treatment:area under the cooling and rewarming curve (AUC) and mean ischemic time of one hand assessed by cooling and recovery photo-electric plethysmography (PPG, BIOPAC), For each treatment: regions of interest peripheral blood perfusion of same hand by FLIR thermography system (FLIR E53)
Detailed description
Pharmacokinetics: Determination and comparison of AUC0-t, AUC0-inf Cmax after increasing dose regimens of intravenously administered STS, Pharmacokinetics: Determination and comparison of steady-state levels after increasing dose regimens of intravenously administered STS, Pharmacokinetics: Determination and comparison of elimination PK parameters after increasing dose regimens of intravenously administered STS, Pharmacokinetics: Determination of endogenous STS levels (based on various pre-dose levels) in Raynaud’s patients, Safety and tolerability as evidenced by: Incidence of treatment-emergent adverse events (TEAEs), Safety and tolerability as evidenced by: ECG, Safety and tolerability as evidenced by: Continuous blood pressure measurement (Finapress), Safety and tolerability as evidenced by: Local tolerability at vein of intravenous administration, Pharmacodynamics: Oxidative stress (systemic free thiols, plasma malondialdehyde (MDA)), Pharmacodynamics: Inflammation (circulating pro-inflammatory cytokines e.g. IL-6, IL-1 beta and TNFalpha), Pharmacodynamics: Endothelial activation (circulating adhesion molecules)
