NCT01082302	Pharmacokinetic Study of Topically Applied Veregen 15% Compared With Oral Intake of Green Tea Beverage	Completed	Charité Research Organization GmbH	Phase 4	This open, monocentric study is designed to investigate plasma concentrations of certain catechins after topical application of Veregen 15% ointment to genital or perianal warts in comparison to catechin plasma concentrations after oral intake of a defined dose of green tea beverage. The study is intended to demonstrate that topical administration of Veregen 15% induces catechin plasma concentrations lower or equivalent to those that can be reached with normal consumption of green tea.

NCT01222000	Treatment of the Recessive Nonbullous Congenital Ichthyosis by the Epigallocatechine Cutaneous	Unknown status	Centre Hospitalier Universitaire de Nice	Phase 3	Lamellar ichthyosis (IL) is a rare autosomal recessive genodermatosis with a defect of keratinization of the skin which results in a severe generalized cutaneous xerosis with dark brown big scales, an ectropion, an eclabion, an alopecia and a palmo-plantar keratodermia. They are due to mutations of the gene TGM1 coding for the transglutaminase keratinocyte 1 (TG1) in 1/3 of the cases. Other genes were recently identified, ABCA12 coding for the triphosphate-binding adenosine cassette A12 and FLJ39501 which codes for a protein of the cytochrome p450 ( CYP4F2). No etiological treatment is available. Symptomatic treatment consists on twice application of emollients and keratolytic ointments which decrease the dryness of the skin and reduce scales. Oral isotretinoin is usually partially effective but is only suspensive and has numerous side effects. Recent studies showed that the epigallocatechin-3-gallate (POLYPHENON E®), extracted from green tea increases the differentiation of the normal human keratinocytes, as showedb by the increase of the involucrine, TG1 and caspase-14 genes expression. The main objective of this pilot study is to estimate the action and the tolerance of a daily application of topical Polyphénon E 10% ® to improve the desquamation and the cutaneous roughness of patients with lamellar ichthyosis, after 4 weeks of treatment. The secondary objectives - To estimate the duration of remission obtained after the treatment - To estimate the action of cutaneous Veregen® to improve the palmar and plantar involvement. - To estimate the action of cutaneous Veregen on the pruritus - And to estimate the global level of acceptability by the patient of the Veregen 10 %
NCT01490008	Systemic Exposure of Catechins From Veregen 15% Ointment in Patients With External Anogenital Warts and From Oral Intake of Green Tea Beverage in Healthy Volunteers	Completed	MediGene	Phase 1	Investigation of systemic catechin exposure following topically administered Veregen® 15% ointment in patients with external genital and perianal warts and following oral intake of a standardized green tea beverage in healthy subjects. Pharmacokinetic parameters for the main catechin EGCg used as a marker of overall catechin exposure following dermal administration in the patient group will only be calculated if sufficiently consistent data can be obtained e.g. sufficient plasma catechin concentrations to pharmacokinetically evaluate plasma profiles for plasma catechin concentrations. If applicable, a safety margin for ointment use might need to be established with respect to intolerable systemic exposures of catechins following application of Veregen® ointment. In treatment arm 1, patients with anogenital warts will apply Veregen® 15% ointment 250 mg three times daily: in the morning, at midday, and in the evening on the defined anogenital administration area (total dose of 750 mg/d) for one week . In treatment arm 2, healthy subjects will ingest 500 mL commercially available green tea beverage ("Lipton® Green Limone" distributed by PepsiCo Deutschland GmbH, Neu-Isenburg, Germany), three times daily in the morning, at midday, and in the evening (total dose of 1500 mL/d) for one week. Plasma samples will be collected to aim for a complete pharmacokinetic assessment (over 24 hours) on Days 1 and 2 at Visit 2 and on Days 7 and 8 at Visit 3 (one week after first dosing). To avoid any influence on overall systemic catechin exposure deriving from any other source than Veregen® or Lipton Green Tea, all subjects participating in the trial (patients and healthy volunteers) will be asked to follow a defined diet abstaining from food or beverages known to containing catechins (a list of all prohibited and allowed foods and beverages will be provided to all subjects). For concomitant medication, only paracetamol and oral contraceptives are allowed.
