In episode 119 of Cell & Gene The Podcast, Host Erin Harris talks to Dr. Norman Putzki, Global Head Clinical Development, Novartis, about the FDA approval of Itvisma, now the only gene replacement therapy approved for children, adolescents, and adults with spinal muscular atrophy (SMA). Dr. Putzki walks us through the six-year development journey behind the STEER and STRENGTH Phase 3 programs. And we explore what the expanded age-range label means for patients who were previously left behind, why intrathecal, fixed-dose AAV delivery represents a pivotal advance for safety, efficacy, and scalability. He details how the Itvisma program is informing Novartis’ broader gene therapy strategy across neuromuscular and CNS diseases, and more.

In Episode 118, Host Erin Harris talks to Alexander Cryer, Ph.D., Instructor in Medicine at Mass General Brigham, about a proof of concept strategy that reprograms tumor cells with mRNA lipid nanoparticles to overactivate the cGAS-STING pathway, forcing cancer cells to produce and export large amounts of the innate immune agonist cGAMP to stimulate surrounding immune cells and drive anti-tumor immunity. Dr. Cryer explains the basic biology of cGAS-STING and how his team restored this pathway in tumor cells and leveraged intratumoral LNP delivery to overcome nucleic acid delivery and targeting challenges. He also discusses future directions, the need to move beyond intratumoral administration with more targeted systemic delivery, and the broader concept of turning the tumor’s own abundant cell population and evolutionarily conserved innate immune pathways into therapeutic allies rather than obstacles.

In episode 116 of Cell & Gene: The Podcast, Host Erin Harris talks to Dr. Arun Upadhyay, Chief Scientific officer, Head of Research and Development at Ocugen to discuss how the company’s modifier gene therapy platform is redefining treatment possibilities for inherited retinal diseases such as retinitis pigmentosa, Stargardt disease, and geographic atrophy. Dr. Upadhyay explains how Ocugen’s gene-agnostic approach differs from traditional single-gene therapies by targeting shared disease pathways to preserve photoreceptors and slow vision loss across diverse genetic mutations. He also shares key lessons learned from advancing OCU400, the first modifier gene therapy to receive a broad FDA indication for retinitis pigmentosa, including challenges in clinical trial design, endpoint selection, and manufacturing scalability.

On episode 114 of Cell & Gene: The Podcast, Host Erin Harris talks to Brian Culley, CEO of Lineage Cell Therapeutics, about advancing cell therapy beyond oncology and into transformative treatments for conditions such as spinal cord injury and blindness. Culley shares how Lineage’s allogeneic, off-the-shelf approach, anchored by its OPC1 program, aims to replace lost or damaged cells to restore function, starting with patients who have plateaued after chronic spinal cord injury. He details the DOSED study’s innovative delivery device and thaw-and-inject formulation, both designed to simplify administration, enhance safety, and improve patient access. Harris and Culley also explore Lineage's broader vision for commercial viability in cell transplantation and its collaborative work with the Christopher & Dana Reeve Foundation to drive awareness, research, and investment in spinal cord injury therapies.

Welcome to Episode 113 of Cell & Gene: The Podcast. Host Erin Harris is joined by Thorsten Gorba, Ph.D., VP Process Development at Aspen Neuroscience to explore how the company is advancing the field of cell therapy manufacturing. Aspen Neuroscience stands at the forefront of integrating machine vision and AI/ML to assess induced pluripotent stem cell (iPSC) colony quality by offering a transformative approach to move beyond the subjective nature of manual evaluation. Dr. Gorba discusses how these technologies bolster reproducibility and scalability and help reduce variability in starting materials. He also covers the regulatory angle, including how the FDA is evaluating digital quality control tools.
