Brief 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.

Exclusion criteria
1. Subject has eczema, scleroderma, psoriasis, dermatitis, or keloids, tumors, ulcers, burns, flaps or grafts on their fingers or any other abnormality of the skin which, in the opinion of the investigator may interfere with the study assessments. 2. Subject has excessive hair growth on the fingers. 3. Subject cannot avoid excessive tanning (any exposure to sunlight or a tanning bed which would cause a sunburn reaction) throughout the study. 4. Subject has a history of significant severe (drug) allergies. 5. Subject uses any prescription or non-prescription drugs on a regular basis which, in the investigator's opinion, might confound the results of the study. 6. Subject currently uses lotions, oils, depilatory preparations, makeup, or other topical treatments on the fingers on a regular basis which cannot be discontinued for the duration of the study. 7. Subject is unable to refrain from drinking alcohol 24 hours prior to each study visit, is currently a regular user of any illicit drugs, or has a history of drug (including alcohol) abuse. 8. Subject is unable to refrain from drinking caffeinated beverages (e.g. coffee, tea, cola, …) 24 hours prior to each study visit. Subject is unable to limit their intake of caffeinated beverages to ≤4 cups a day throughout the study. 9. Subject has any of the following vital sign measurements at screening after at least 10 minutes of supine rest: Heart Rate \<40 or \>100 beats/min, Diastolic Blood Pressure \<50 or \>90 mmHg, Systolic Blood Pressure \<90 or \>140 mmHg. 10.
