• Common warts are estimated to affect 10 percent of the global population

• Currently no FDA-approved prescription treatment

• Phase III patient enrollment expected to start in the second half of 2023

SAN DIEGO--(BUSINESS WIRE)--Nielsen BioSciences, Inc. (“Nielsen”), a privately-held, San Diego-based biopharmaceutical company, today announced that it has entered into a license agreement with Maruho Co., Ltd. (“Maruho”), granting Maruho exclusive rights to market CANDIN^Ⓡ in Japan for the treatment of Verruca vulgaris (common warts). CANDIN is an approved diagnostic skin test and currently not approved by the FDA or Japan’s PMDA for the treatment of common warts. Enrollment in Nielsen’s phase III trial for common warts treatment is expected to begin in the second half of 2023.

Under the terms of the license agreement, Nielsen grants Maruho an exclusive license for the post-launch sales and promotional activities of CANDIN in Japan after it is developed by Nielsen and approved by regulatory authorities. For the exclusive Japanese license, Maruho will pay Nielsen a substantial upfront payment, and additional development, regulatory and sales milestone payments based on outcomes. With the upfront payment and milestones, Nielsen has the potential to earn greater than $100 million from the license agreement with Maruho.

Nielsen has one United States Patent and one United States Patent Application, as well as 10 Patent Applications outside the U.S., which is associated with its development and use of CANDIN.

“Verruca vulgaris is not purely cosmetic in nature and can cause physical discomfort, bleeding, and psychological distress. It can also lead to other more serious conditions if left untreated. There is currently no FDA-approved prescription treatment,” said David P. Burney, PhD, MBA, President and COO at Nielsen BioSciences. “We are proud to continue the development of this potential new therapy and make it available to patients in need.”

Verruca vulgaris are benign lesions caused by infection of the skin with the human papillomavirus (HPV). They are raised lesions on the skin, commonly on the fingers, palms, knees, and soles of the feet. Since warts are caused by a viral infection, skin symptoms can be widespread and refractory. Common warts are estimated to affect 10 percent of the global population.¹

“This immunotherapy biologic holds great promise for providing patients with a non-invasive form of treatment for the millions of people who develop common warts yearly,” said H. Stewart Nielsen, Jr., Ph.D., Vice Chairman and Founder of Nielsen BioSciences. “The investigational treatment is given via an injection, which promises to be a potential improvement to standard removal of the wart via acid, surgery, cryotherapy and other methods that can damage skin.”

Raymond James acted as the financial advisor to Nielsen on this transaction.
