DFB Soria Gives Update on Enrollment in Phase 2 Clinical Trial of SOR007 (Nanoparticle Paclitaxel) Ointment for Actinic Keratosis (AK)

AK can lead to the second most common form of skin cancer 

DALLAS/FT.WORTH, (September 26, 2017) —DFB Soria, a clinical-stage pharmaceutical development company, and an affiliate of NanOlogy™, today announced completion of the second of four patient cohorts enrolled in a Phase 2 actinic keratosis (AK) clinical trial of a topical ointment containing nanoparticle paclitaxel formed by a proprietary production process. Identified as SOR007, the ointment is being evaluated topically in a dose escalating trial for safety and preliminary efficacy.

“The most widely prescribed topical treatment for AK is 5-fluorouracil, which causes severe dermal irritation and significantly decreases the patient’s quality of life for several weeks.” said Gere diZerega, MD, Soria VP of Medical Affairs. “Preclinical dermal irritation studies and a Phase 1 clinical trial of SOR007 showed minimal dermal irritation and negligible systemic absorption, and formed the basis for FDA approving the clinical protocol for our AK trial.”

AK is a precancerous condition caused primarily by exposure to the sun, and affects an estimated 58 million Americans. If left untreated, AK can progress to cutaneous squamous cell carcinoma (CSCC), the second most common form of skin cancer. More than one million people are diagnosed with CSCC each year, and as many as 9,000 people die from the disease. Paclitaxel administered systemically is effective in the treatment of advanced CSCC but can cause systemic adverse effects.

“Our goal is to demonstrate that SOR007 is effective without the severe topical irritation that limits other AK products.” said Maxwell Lea of Soria. “Successful results from this clinical trial will allow selection of the most efficacious SOR007 concentration to move forward into phase 3-enabling clinical trials.”

Nanoparticle paclitaxel contained in SOR007 is produced by a proprietary nanoparticle production technology that reduces the size of unprocessed paclitaxel API crystals up to 400 times into patented, stable, naked nanoparticles with exponentially increased surface area and unique geometry. NanoPac is then suspended in a topical anhydrous base, which has successfully shown penetration of the drug through the epidermis into the dermis. Both the nanoparticle and the ointment are patent pending.

Nanology and Soria share a common nanoparticle technology platform that is currently in six clinical trials for evaluation in ovarian cancer (with orphan drug status), prostate cancer,

pancreatic cancer, pancreatic mucinous cysts, cutaneous metastases, and actinic keratosis. In addition, preclinical studies are underway for lung cancer and bladder cancer.
