Atsena closes $150m in Series C round to progress gene therapy
Atsena Therapeutics has completed an oversubscribed Series C financing round, raising $150m to support the advancement of its lead gene therapy programme, ATSN-201, to treat X-linked retinoschisis (XLRS). The funds are to be used to further develop its preclinical pipeline of therapies and broaden the usage of the company's adeno-associated virus with laterally spreading capsid. Bain Capital's Life Sciences team headed the funding round, with contributions from new investor Wellington Management. Current investors such as Lightstone Ventures, Abingworth, Foundation Fighting Blindness and Hatteras Venture Partners participated in this latest round. XLRS is a condition that leads to blindness and is typically diagnosed in childhood. Atsena's clinical portfolio has already gained US Food and Drug Administration (FDA) rare paediatric disease and orphan drug designations for both ATSN-101 and ATSN-201. ATSN-101, which targets Leber Congenital Amaurosis type 1 (LCA1), has also been granted the regenerative medicine advanced therapy designation. Updated outcomes from the ongoing Phase I/II LIGHTHOUSE trial of ATSN-201 are expected in late 2025. The company also welcomed biopharmaceutical executive and scientist Dr Norbert Riedel to its board of directors. For the Series C financing, Wedbush & Co acted as exclusive placement agent to the company, while Cooley provided legal counsel. Atsena's investigational gene therapy, ATSN-101, has shown positive outcomes in a Phase I/II trial and is moving towards a pivotal trial in partnership with Nippon Shinyaku. The company's pipeline leverages adeno-associated virus technology designed to address the challenges of inherited retinal conditions. In March 2025, the company received fast track designation from the FDA for ATSN-201 to treat XLRS.

Atsena Therapeutics Granted U.S. FDA Fast Track Designation for ATSN-201 Gene Therapy to Treat X-linked Retinoschisis
Marks third FDA designation for ATSN-201, which has also received Rare Pediatric Disease Designation and Orphan Drug Designation DURHAM, N.C., March 12, 2025 (GLOBE NEWSWIRE) -- Atsena Therapeutics, a clinical-stage gene therapy company focused on using the life-changing power of genetic medicine to reverse or prevent blindness, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ATSN-201 for the treatment of X-linked retinoschisis (XLRS). ATSN-201, a best-in-class gene therapy product candidate, leverages the company's novel spreading capsid, to achieve therapeutic levels of gene expression in photoreceptors of the central retina while avoiding the surgical risks of foveal detachment. 'We are pleased that the FDA has granted Fast Track designation to ATSN-201, reinforcing its potential to address the significant unmet need in XLRS, a rare inherited retinal disease with no approved treatments,' said Patrick Ritschel, Chief Executive Officer of Atsena Therapeutics. 'This designation, along with the previously granted Orphan Drug and Rare Pediatric Disease designations, marks an important milestone in advancing the development of ATSN-201. The Atsena team remains dedicated to developing transformative gene therapies and improving the quality of life of individuals suffering from XLRS and other inherited retinal diseases.' Fast Track designation is granted to treatments intended to address serious or life-threatening diseases that have demonstrated the potential to meet an unmet medical need. Treatments that receive Fast Track designation may benefit from more frequent interactions with the FDA throughout drug development. In addition, the Fast Track program allows for Priority Review, if relevant criteria are met. Currently, there are no approved treatments for XLRS, which is typically diagnosed in early childhood and affects approximately 30,000 males in the U.S. and the EU. The safety and tolerability of ATSN-201 is currently being evaluated in the LIGHTHOUSE study, a Phase I/II, dose-escalation and dose-expansion clinical trial in male patients ages six and older with a clinical diagnosis of XLRS caused by mutations in the RS1 gene. Enrollment for this study is ongoing. For more information, visit (Identifier: NCT05878860). About X-linked Retinoschisis (XLRS)XLRS is a monogenic X-linked disease caused by mutations in the RS1 gene which encodes retinoschisin, a protein secreted primarily by photoreceptors. RS1 is localized to the extracellular surface of rods, cones, and bipolar cells. XLRS is characterized by schisis, or abnormal splitting of retinal layers, which causes impaired visual acuity that is not correctable with glasses and leads to progressive vision loss and ultimately blindness. XLRS primarily affects males and is typically diagnosed in early childhood. Approximately 30,000 males in the U.S. and EU have XLRS, for which there are currently no approved treatments. About one of Atsena's novel capsids, spreads laterally beyond the subretinal injection site to enable safe and efficient transduction of the central retina (where schisis cavities predominate in XLRS patient retinas) when injected into areas outside the macula. A preclinical study in non-human primates demonstrated that promotes transgene expression well beyond subretinal injection bleb margins. This is in contrast to benchmark AAV vectors, which remain confined to the original bleb margins. At clinically relevant doses, efficiently transduces foveal cones without the need for surgical detachment and has a favorable safety profile relative to benchmark capsids. For more information about the preclinical study and how works, visit About Atsena TherapeuticsAtsena Therapeutics ('Atsena') is a clinical-stage gene therapy company developing best-in-class treatments for the reversal or prevention of blindness from inherited retinal diseases. The company's lead program is evaluating ATSN-201 in an ongoing Phase I/II clinical trial for X-linked retinoschisis (XLRS), a genetic condition that is typically diagnosed in childhood and leads to blindness later in life. ATSN-101, Atsena's first-in-class, investigational gene therapy for Leber congenital amaurosis type 1 (LCA1), one of the most common causes of blindness in children, has completed a Phase 1 / 2 trial with positive results ( Atsena is advancing ATSN-101 toward the initiation of a global pivotal trial as part of its exclusive strategic collaboration with Nippon Shinyaku Co., Ltd. Atsena's pipeline is powered by novel adeno-associated virus (AAV) technology tailored to overcome the hurdles presented by inherited retinal diseases. Founded by pioneers in ocular gene therapy, Atsena is led by an experienced team dedicated to addressing the needs of patients with vision loss.
