Generex Biotechnology Subsidiary Olaregen Therapeutix Inc. Plans Launch of FDA Cleared Excellagen Wound Conforming Gel Matrix with Three Dosage Options

MIRAMAR, FL, January 11, 2019 - Generex Biotechnology Corporation (OTCQB:GNBT) is pleased to announce that Olaregen Therapeutix Inc., a subsidiary of Generex Biotechnology will launch three doses of FDA 510K-Cleared, Excellagen, the company’s wound conforming gel matrix that is designated as a Cellular & Tissue Based Product or CTP for wound healing. The 0.5 cc and a 0.8 cc syringes will be utilized to treat smaller wounds such as diabetic foot ulcers, venous stasis ulcers, and pressure ulcers, and in patients who have undergone MOHs surgery for removal of cancerous tissue. The 3cc syringe has been developed for larger wounds that are most frequently seen in emergency departments, operating rooms, and surgical suites. Excellagen has a designated reimbursement code in the Healthcare Common Procedure Coding System, with a unique Q Code designation 4149 referred to as a skin substitute.

The Excellagen® launch team is introducing the product in surgical centers, the Department of Defense and VA system, operating rooms, and wound care centers, as well as through podiatric practices. The company is currently in contract negotiations with major nation-wide surgical wound care centers for the use of Excellagen® for the treatment of a variety of wound types, including partial and full thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds (donor sites/grafts, post-Mohs surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, second-degree burns, and skin tears) and draining wounds. Additionally, NuGenerex Distribution Solutions, a wholly-owned subsidiary of Generex, will immediately launch Excellagen® through its MSO network of surgeons and podiatrists in five states.

“We’ve heard time and again about the issue of waste, or the need for multiple applications per a single procedure because the existing products don’t necessarily accommodate the size of the wound. This is not only time consuming for the doctor but is cost inefficient,” said Anthony J. Dolisi, Chief Executive Officer of Olaregen. “As part of our commitment to our customers, we listen carefully to their needs. After a thorough analysis of the market, and through discussions with physicians, we determined that Olaregen will launch Excellagen with multiple dosage options that offer clinical flexibility and cost savings with improved clinical outcomes.”Dr. Peter Blume, D.P. M., F. A. C. F. A. S., Medical Director/HVC/Ambulatory Surgery, Yale New Haven Health Systems, Assistant Clinical Professor Of Surgery Anesthesia and Cardiology, Yale School of Medicine provides his views on Excellagen%uF0D2, ““The average wound size in the surgical setting can be variable and quite large depending on the amount of debridement of soft tissue and bone. Olaregen’s decision to manufacture a 0.5cc and a 0.8cc for smaller wounds such as DFU, VSU and Pressure ulcers and a 3cc syringe for the surgical setting will not only save doctors time but will be highly cost effective and reduce product waste. The company is collaborating with physicians and surgeons with respect to the needs of the wound care community and addressing the unmet needs.”

The wound care market is extensive, with an estimated 77 million surgical wounds in the U.S., a percentage of which Excellegen is cleared for use. The wound conforming gel is also indicated to treat Diabetic Foot Ulcers (1,260,000), Venous Stasis Ulcers (1,625,000), and MOHs surgery (850,000) among the 17 wound types Excellagen is cleared to treat. Further, a recent study published in Value in Health (Volume 21, September 2018, 27 – 32) found that total Medicare spending estimates for all wound types ranged from $28.1 to $96.8 billion, as nearly 15% of

Medicare beneficiaries or 8.2 million people had at least one type of wound or tissue infection. These figures do not reflect the incidence of burns, amputations, and traumatic wounds and lacerations all which Excellagen is cleared for use. With the aging population and the increase in the incidence of diabetes, these numbers are expected to grow significantly in the future.

Anthony J. Dolisi, Chief Executive Officer provided his view of the market, “We have created awound care expert salesforce to help guide physicians on the optimal Excellegen dose for a given wound type. As an example, in the surgical setting, a 3cc pre-filled syringe of Excellagen will cost substantially less than our CTP competitors with demonstrated improvements in healing rates.Olaregen is aggressively pursuing a “Value Based Healthcare” strategy in line with the goals ofthe Centers for Medicare and Medicaid Services, which has announced that they will be assessing waste in the wound care system. Discarding unused wound care products is a tremendous cost in the wound care space, so our strategy of multiple dosing options puts Olaregen in a strong market position.”
