Summary

Part I: Evaluating the increase in dermal blood flow upon topical application of cinnamaldehyde and capsaicin on the fingers in healthy, male volunteers. In addition, the inter-period and inter-hand reproducibility of the increase in dermal blood flow will be assessed. Part II: Evaluating the increase in dermal blood flow upon topical application of cinnamaldehyde and capsaicin on the fingers in patients suffering from chemotherapy-induced peripheral neuropathy compared to matched healthy volunteers. Part III: Evaluating the increase in dermal blood flow upon topical application of cinnamaldehyde and capsaicin on the fingers in patients who are treated with paclitaxel or oxaliplatin.

Detailed description

The primary aim is to investigate whether paclitaxel and/or oxaliplatin alter TRP channel functionality in vivo in human. TRP functionality can indirectly be assessed via dermal blood flow changes which are part of the so-called neurogenic inflammation, induced upon TRP activation. In vivo in human, TRP can be activated via topical application of cinnamaldehyde or capsaicin on the skin. In Part I of the study, the DBF changes upon topical application of cinnamaldehyde or capsaicin on the fingers will be characterized, including inter-period and inter-hand reproducibility. In Part II, patients who are suffering from chronic CIPN after treatment with paclitaxel or oxaliplatin are included. DBF changes upon cinnamaldehyde and capsaicin are compared to a matched control group. In Part III, DBF changes are assessed in patients prior to the first administration of taxol/oxaliplatin and at regular points in time during the dosage regimen.
