E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Part II – Safety and Primary Efficacy evaluation
• To demonstrate the safety of ATH008 cream in patients presenting PPES secondary to capecitabine therapy.

|
|
E.2.2 | Secondary objectives of the trial |

• To determine the plasmatic levels of the active ingredient, allopurinol, and its metabolite, oxypurinol, when given topically.
• To demonstrate the efficacy of ATH008 cream in improving the quality of life of patients presenting PPES.
• To demonstrate the efficacy of ATH008 cream in improving the signs and symptoms of PPES.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Have signed Informed Consent.
• Are under capecitabine therapy for treatment of colon or breast cancer at a regimen of 2 weeks on and 1 week off (14+7) and a daily doses between 2000 and 2500 mg/m2.
• Diagnosis of PPES grade 1 in any hand or foot according to the NCI CTCAE v4.03 definition.
• Are able to apply topical medication or provide for another person to apply it.

|
|
E.4 | Principal exclusion criteria |
• Are younger than 18 years.
• Diagnosis of PPES grade 1in any hand or foot according to the NCI CTCAE v4.03 definition for more than 2 cycles previously to inclusion in this clinical study.
• Use of other chemotherapies for the treatment of cancer except trastuzumab (Herceptin®) or bevacizumab (Avastin®).
• Haematological limits indicating that capecitabine (Xeloda®) cannot be administered due to safety reasons, based on the PI review before each cycle of chemotherapy.
• Total bilirubin > 3 upper normal value.
• Serum creatinine level > 2 upper normal value.
• Have neurologic symptoms greater than grade 1, which under the criteria of the clinician could interfere with PPES diagnosis or study treatment (e.g. hands or feet neuropathy).
• Have any dermatologic condition that in the opinion of the investigator may affect hands or feet or may complicate evaluation during study treatment (e.g. neurodermatitis, psoriasis, etc).
• Have onycholysis with a non-stable grade 1 or onycholysis greater than grade 1 (nail loss, NCI CTCAE v4.03 criteria) which in the assessment of the clinician could interfere with PPES diagnosis or study treatment.
• Need to use other emollient creams or other topical treatments in hands and/or feet during the study.
• Are receiving radiotherapy.
• Are actively treated with systemic allopurinol (oral or parenteral) for the treatment of gout, or any other indication.
• Have developed a severe reaction to allopurinol in the past (e.g. Lyell syndrome).
• Known allergy to allopurinol or any of the excipients of the product.
• Previous contraindication to treatment with capecitabine.
• Have received topical corticosteroids in hands and/ or feet 7 days prior to planned inclusion in the study.
• Are participating in any other investigational studies for the treatment of PPES.
• Have participated in any other investigational studies for the treatment of PPES, or received an experimental therapeutic procedure, considered to potentially interfere with the study in the 4 weeks preceding Day 1.
• Have a serious medical or psychiatric condition that could, in the investigator’s opinion, potentially interfere with their study treatment or participation in the study.
• Pregnant women, women in child bearing age not using contraceptives or men not using contraceptives. Methods of contraception which have a failure rate (Pearl index) of less than 1% per year are regarded as highly effective.
• Are participating in other clinical trials.
