Under the terms of the agreement, Gene Biotherapeutics will be entitled to a total consideration of up to $4,000,000, consisting of an upfront cash payment totaling $650,000 and $3,350,000 in additional consideration that would consist of royalties on worldwide net sales, and accelerated royalties in the form of lump sum cash payments based on capital investments received by Olaregen or the sale of the Excellagen technology platform to a third party.

Emerging Medical Need for Advanced Wound Care in Asian Markets

A clinical study conducted by researchers at eight leading hospitals and medical centers representing nearly all geographic regions across China has concluded that diabetic foot ulceration represents a serious problem in China, and that more intensive surveillance, more aggressive treatment, and earlier referral to specialty care are required to improve patient outcomes.  The study reported that there are approximately 114 million Chinese adults with diabetes and 493 million Chinese adults with pre-diabetes.  The study shows that the prevalence of diabetic foot ulcers has increased from 4.91% in 1996 to 35.3% in 2008 and has been "a heavy burden for health care resources, with an average hospital stay of 31 days and a medical cost of 17,181 yuan RMB."  It was also reported that the incidence of diabetic foot ulcers and amputation in China are much higher that of Western countries [Jiang et al., Wound Repair and Regeneration, 2015. DOI: 10.1111/wrr.12263].

Excellagen® Advanced Dermal Wound Matrix

Excellagen® is an FDA-cleared, flowable dermal matrix indicated for the treatment of hard to heal wounds such as diabetic foot ulcers and pressure ulcers as well as other dermal wounds. Excellagen is supplied in the form of a physiologically formulated homogenate of purified bovine dermal collagen (Type I) in its native 3-dimensional fibrillar configuration. Excellagen® can activate platelets, triggering release of essential growth factors and is capable of providing a structural scaffold for cellular infiltration and migration, significantly accelerating the growth of granulation tissue. Excellagen's unique flowable fibrillar collagen formulation is topically applied through easy-to-control, pre-filled sterile syringes and is designed for application at once weekly intervals.  Excellagen® has been designated as a skin substitute (bearing a unique product Q Code), in accordance with the standards established by the U.S. Centers for Medicare and Medicaid Services (CMS).

On June 7, 2017, Gene Biotherapeutics received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for a new patent (U.S. Patent #9,782, 457) entitled "Flowable Formulations for Tissue Repair and Regeneration." The patent application includes claims covering methods to utilize formulations encompassing Excellagen [2.6%] as a topically applied flowable fibrillar collagen matrix for wound repair by promoting localized release of platelet derived growth factors and providing an in situ microstructural scaffold for cell migration. On February 12, 2018, Gene Biotherapeutics received a Notice of Allowance for a patent with the same title and similar claims from the State Intellectual Property Office of China (CN Application #2013800634138).  The U.S. patent is transferred to Olaregen as part of this transaction, whereas Gene Biotherapeutics retains the China patent.
