Efficacy Study & Safety Evaluation of SR-T100 Gel in Actinic Keratosis Treatment
17 de fevereiro de 2016 atualizado por: G&E Herbal Biotechnology Co., LTD
A Randomized, Double-Blind, Parallel, Vehicle-Controlled Phase III Trial to Assess the Efficacy and Safety of Topical SR-T100 Gel in the Treatment of Patients With Actinic Keratosis
Studies of SR-T100 gel and its clinical relevance in the treatment of AK, providing adequate measured outcomes for skin lesion treatment.
In addition to the high complete response rate (90.0%) as compared with the conventional therapy, the most significant result was that no undesirable side effects were associated with the use of SR-T100 gel.
The result also shows approximately 80% of study subjects had a complete response in phase II clinical trial conducted in Taiwan; hence, result from our study model suggested SR-T100 gel offers beneficial therapeutic values in treatment of AK is harmless to the skin as well as high tolerance level displayed by majority of patients.

Descrição detalhada
The primary objective of this study is to demonstrate a clinically significant outcome involving SR-T100 topical gel developed against skin lesions such as AK.
Furthermore, evaluation of SR-T100 efficacy & tolerability in treating AK lesions are developed as secondary objective in this clinical study.
Patients with at least two clinically visible, discrete, non-hyperkeratotic, non-hypertrophic AK lesions on the arms, shoulder, chest, face and or scalp and at least one lesion of greater than or equal to 4mm in diameter within a total of 25 cm squared contiguous or non-contiguous treatment are expected to be enrolled.
Candidate pool is then divided into two groups with random assignments of treatment group or placebo group.
This randomization scheme will be generated by biostatistics and produced by a computer software program that incorporates a standard procedure for generating random probabilities.
Study procedures include laboratory testings, analytical readings as well as clinical assessment practices for treatment efficacy and safety evaluations.

|---|---|
|
Experimental: SR-T100 gel
Patient group receiving medication SR-T100 gel with active ingredient under investigation, enrolled subjects randomly assigned to this group to accurately depict statistical significance of the measured outcome.
|
Patient will be instructed to self-apply approximately 0.3~0.5g of SR-T100 gel on 25 cm squared treatment area (avoiding the periocular areas, lips, and nares) once daily with an occlusive dressing for 16 weeks treatment period.

Comparador Ativo: Vehicle gel
Patients given placebo with non-SR-T100 ingredients as they are being administered to patients, subjects are under random assignments from patient pool to depict statistically significant outcome measurement.
|
Patient wil be instructed to self-apply approximately 0.3~0.5g of vehicle gel (without active ingredient)per total of 25 cm squared treatment area (avoiding the periocular areas, lips, and nares) once daily with an occlusive dressing for 16 weeks treatment period.
