Vigene Biosciences Secures Institutional Investment in New Round of Growth Capital Financing

ROCKVILLE, Md., April 29, 2019 /PRNewswire/ -- Vigene Biosciences, Inc ("Vigene") a leading provider of viral vector products and services used in gene therapy, has completed a substantial growth capital financing transaction. The investment was made by Signet Healthcare Partners ("Signet"), a New York based growth equity firm specializing in healthcare investments.

The growth capital will be used to support Vigene's expansion into a new facility to support the growing demand for viral vector and plasmid production in the rapidly expanding fields of cell and gene therapy. Construction of the new facility, located in Rockville, Maryland, is set to be completed mid-2019 and will increase Vigene's office, laboratory and cGMP production space by 51,000 sq. ft. The most notable additions from the expansion are 5 state-of-the-art cGMP viral manufacturing suites, which will increase Vigene's cGMP production facilities to 10 suites with over 30,000 sq. ft. of cGMP space.

Vigene CEO Dr. Zairen Sun said, "We are very excited to receive this investment, which will allow us to accelerate the growth of our business. Signet Healthcare Partners is an ideal partner in further developing Vigene as a leader in the Contract Development and Manufacturing Organization (CDMO) space for viral vector cGMP production. The new facility and equipment will allow us to innovate and meet production demands as the fields of gene and cell therapy continue to advance."

Concurrently with the financing, Ashley Friedman, Managing Director at Signet Healthcare Partners, will join the board of directors at Vigene. "I believe the company is well positioned to capitalize on the rapidly evolving field of gene therapy. Signet looks forward to a close collaboration with Dr. Sun and the leadership team at Vigene," said Ashley Friedman. Additionally, Jeffrey M Ostrove, Ph.D. will be joining Vigene as an Independent member of the board of directors. Dr. Ostrove is a biotechnology executive with extensive experience in gene therapy, both on the drug development and CDMO side of the business. Dr. Ostrove is currently the CEO of Locana Inc. "There is a great need for additional contract manufacturing and support services in the fields of cell and gene therapy as the FDA predicts there will be over 200 Investigational New Drug applications filed over the next 2 years which represents a substantial expansion of the field and Vigene is poised to support that effort," stated Dr. Ostrove.
