Provectus Biopharmaceuticals begins recruitment for phase 2 mechanism of action clinical trial of PH-10 for psoriasis

Provectus Biopharmaceuticals, Inc., a development-stage oncology and dermatology biopharmaceutical company (“Provectus”), has announced that it has opened recruitment for its phase 2 mechanism of action trial of PH-10 for the treatment of mild to moderate psoriasis. The purpose of the trial is to study the safety and efficacy of PH-10, a 0.005% preparation of Rose Bengal, in the treatment of psoriasis.

Officially titled, “A Phase 2 Study of Cellular and Immunologic Changes in the Skin of Subjects Receiving PH-10 Aqueous Hydrogel to Plaque Psoriasis,” total enrollment is expected to consist of 30 patients. Subjects will apply PH-10 vehicle daily for 28 consecutive days followed by active PH-10 daily for 28 consecutive days to their plaque psoriasis areas on the trunk or extremities (excluding palms, soles, scalp, facial and intertriginous sites). Biopsies of one target plaque will be collected at baseline (at least 7 days prior to first study treatment on Day 1) and at Days 29 and 64, with a 7-day interval between biopsy at Day 29 at the end of vehicle application and commencement of application of active PH-10 on Day 36. Study data from each subject will serve as an internal control (i.e., with assessment at baseline and at the end of application of PH-10 vehicle) for evaluation of clinical and cellular response to active investigational agent.

Eric Watcher, CTO of Provectus, stated, “We are very excited to begin this study. PH-10 has already been testing phase 1 and 2 studies and a total of 226 patients. In this study, we are looking at possible changes in the immunologic, structural and hyperproliferative state of the skin in the target plaque and evidence of cellular atypia following PH-10 application. We will use this data to aid in further development of PH-10 with our objective to co-develop or license PH-10 with dermatological partner as we continue to prepare to advance PH-10 for approval as topical anti-inflammatory non-steroidal agent for treating psoriasis and other inflammatory dermatoses.”

According to clinicaltrials.gov, the estimated completion date of the study is January 2016, and further information is available at https://clinicaltrials.gov/ct2/show/record/NCT02322086
