Atsena Therapeutics Raises $55 Million Series A Financing to Advance LCA1 Gene Therapy Clinical Program, Two Preclinical Assets, and Novel Capsid Development for Ocular Diseases

  • Round was led by Sofinnova Investments with participation from Abingworth, Lightstone Ventures and all existing investors
  • Company expands board of directors and plans to build out team

DURHAM, NC and BOSTON, MA – Atsena Therapeutics, a clinical-stage gene therapy company focused on bringing the life-changing power of genetic medicine to reverse or prevent blindness, today announced it has closed an oversubscribed $55 million Series A financing led by Sofinnova Investments with participation from additional new investors Abingworth and Lightstone Ventures. Founding investors Hatteras Venture Partners and the Foundation Fighting Blindness’ RD Fund, along with existing investors Osage University Partners, University of Florida, and Manning Family Foundation, also participated in the round. Sarah Bhagat, PhD, Partner at Sofinnova, Jackie Grant, PhD, Principal at Abingworth, and Jason Lettmann, General Partner at Lightstone, will join Atsena’s board of directors.

Proceeds will be used to advance Atsena’s ongoing Phase I/II clinical trial evaluating a gene therapy for patients with GUCY2D-associated Leber congenital amaurosis (LCA1), one of the most common causes of blindness in children, as well as complete manufacturing development for Phase 3. In addition, the funds will enable Atsena to expand its team to support the research and development of novel gene therapies, including the progression of two existing preclinical programs in inherited retinal diseases toward the clinic and advancement of the company’s innovative adeno-associated virus (AAV) technology platform.

“We are grateful for the support of our new and existing investors and are encouraged by their enthusiasm for the potential of our technology to overcome the unique hurdles of inherited retinal diseases to prevent or reverse blindness,” said Patrick Ritschel, MBA, Chief Executive Officer of Atsena. “The Series A financing provides financial runway to reach the key inflection point of reading out efficacy data from our LCA1 clinical trial. While we continue expeditiously advancing this trial and our preclinical programs, we are excited to accelerate our growth as a leading ophthalmic gene therapy company.”

The Phase I/II LCA1 clinical trial is currently enrolling patients in the second dosing cohort. Atsena exclusively licensed the rights to the gene therapy from Sanofi, which originally licensed it from University of Florida. LCA is the most common cause of blindness in children. LCA1 is caused by mutations in the GUCY2D gene and results in early and severe vision impairment or blindness. GUCY2D-LCA1 is one of the most common forms of LCA, affecting roughly 20 percent of patients who live with this inherited retinal disease.

“We believe Atsena’s foundation in ocular gene therapy and potentially game-changing novel AAV vectors position the company to become a partner of choice,” said Dr. Bhagat. “Sofinnova is delighted to support Atsena and we look forward to helping the team further its mission to develop life-changing gene therapies for patients with inherited retinal diseases.”

Atsena Therapeutics acquires exclusive rights to Gene Therapy for GUCY2D-associated Leber Congenital Amaurosis

  • Therapy currently being evaluated in Phase I/II clinical study
  • Company formed with $8.15 million Series 1; led by founding investors Hatteras Venture Partners and the Foundation Fighting Blindness

DURHAM, NC – Atsena Therapeutics, a clinical-stage gene therapy company focused on bringing the life-changing power of genetic medicine to reverse or prevent blindness, today announced that it has acquired exclusive rights to a gene therapy targeting GUCY2D-associated Leber congenital amaurosis (LCA1), a genetic eye disease that affects the retina and is a leading cause of blindness in children, from Sanofi, which originally licensed it from the University of Florida. The therapy was created in the laboratory of Atsena Founder and Chief Scientific Officer Shannon Boye, Ph.D., and Founder and Chief Technology Officer Sanford Boye, M.Sc., at the University of Florida.

“We are thrilled that our gene therapy for LCA1 is coming home to Atsena and that we will have the opportunity to further its development,” said Shannon Boye. “Atsena was founded to advance treatments for inherited retinal diseases and believes in centering patients’ perspectives and needs in all we do. We are honored to continue to work with LCA1 patients and their families as we strive to treat this debilitating disease.”

LCA is the most common cause of blindness in children, impacting two to three per 100,000. LCA1 is caused by mutations in the GUCY2D gene and results in early and severe vision impairment or blindness. GUCY2D-LCA1 is one of the most common forms of LCA, affecting roughly 20 percent of patients who live with this inherited retinal disease.

Atsena has an ongoing Phase I/II clinical trial evaluating this gene therapy in LCA1 patients. The second cohort in the trial is expected to be dosed in the fall of 2020.

“Atsena’s gene therapy has the potential to be a major advance in treating blindness in both children and adults affected by this inherited retinal disease,” said Benjamin Yerxa, Ph.D., Chief Executive Officer of the Foundation Fighting Blindness and Atsena board director. “The foundation was instrumental in supporting proof of concept studies in the founders’ labs over the last 15 years. Now, via investment in Atsena through our Retinal Degeneration (RD) Fund, we are excited to support this potential breakthrough treatment for LCA1.”

Atsena closed a Series 1 funding of $8.15 million in April 2020, led by founding investors Hatteras Venture Partners and the Foundation Fighting Blindness’ RD Fund with participation by Osage University Partners, PBM Capital and the University of Florida. Patrick Ritschel, M.B.A., co-founder and former President of gene therapy company StrideBio, serves as Atsena’s Chief Executive Officer.

“Atsena is pleased to have the support of an enthusiastic investor base that shares our dedication to bringing the life-changing power of genetic medicine to patients living with LCA1 and other forms of blindness,” said Ritschel. “We look forward to working closely with our investors and patients as we continue to grow, and expect to announce additional milestones later this year.”
