Scientists from Apertura Gene Therapy and the Broad Institute of MIT and Harvard, will present advancements related to TfR1 CapX™, a leading AAV capsid that leverages human transferrin receptor 1 (hTfR1) to enable intravenous delivery to the brain and spinal cord, at the 29th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT), held May 11–15, 2026 in Boston, MA.
Data presented by Apertura at ASGCT will show that TfR1 CapX can be manufactured at clinically relevant scale, helping reduce one of the biggest bottlenecks in bringing therapies to patients. The company will also present on the utility of different animal models for the preclinical evaluation of novel AAV capsids such as TfR1 CapX, emphasizing that more human-relevant models are critical for more accurately predicting clinical translation.
Apertura will also share how it is expanding access to its innovative TfR1 CapX capsid through its Open Aperture program, which provides academic researchers free access and a practical development playbook aimed at accelerating discovery and enabling more breakthroughs across the field.
"We look forward to sharing Apertura's latest updates with the broader gene therapy community at ASGCT this year," said Andrew Steinsapir, Acting CTO at Apertura and Director & Gene Therapy Program Lead at Deerfield Management.
"The progress we continue to see with TfR1 CapX is a reflection of the dedication of our collaborators, partners, and patient advocacy groups who are all working toward the same goal: advancing new treatment options for patients with serious neurological diseases."
Presentations from the labs of Dr. Sonia Vallabh, Director, Prion Therapeutic Science at the Broad Institute, and Dr. Ben Deverman, Senior Director of Vector Engineering and Institute Scientist at the Broad Institute and Scientific Founder of Apertura, will highlight the versatility of TfR1 CapX across therapeutic approaches. These include epigenetic silencing and base-editing strategies designed to reduce prion protein levels in the brain and advances in capsid engineering that help evade neutralizing antibodies, potentially enabling gene therapies to reach a broader patient population.
"Our recent work shows the versatility of TfR1 CapX with a wide array of gene expression and editing payloads, enabling rapid blood-brain barrier crossing and efficient delivery to cells throughout the central nervous system," Dr. Deverman said. "We are excited to share our findings and help foster a community of open sharing amongst groups using TfR1 CapX to develop gene therapies for the CNS."
