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.

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 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. Subject is currently participating or has been involved in testing an investigational drug in another clinical study within the last 4 weeks. 11. Subject is in a situation or has a condition which, in the opinion of the investigator, may interfere with safe and optimal participation in the study. 12. Subject has a history of any illness or disorder which, in the investigator's opinion, might confound the results of the study. 13.

Subject has (a history of) diabetes mellitus, amyloidosis, vitamin B deficiency or any other medical disorder that, in the investigator's opinion, may cause peripheral neuropathy (only for Part II and III). 15. Subject has (a history of) a lesion in the central nervous system that is known to possibly cause neuropathic pain: e.g. spinal cord injury, infarction localized in the brainstem or thalamus, syringomyelia, multiple sclerosis, or any other disorder of the CNS that, in the investigator's opinion, may cause neuropathic pain (only for Part II and III). 16. Subject has a history of treatment with bortezomib, vincristine, or any other compound that, in the investigator's opinion, may cause neuropathic pain (only for Part II and III). 17.
