RegenXBio Secures $250M in Gene Therapy Royalty Deals, Boosting Cash Runway

RegenXBio, a leading player in gene therapy development, has announced a significant financial maneuver, securing up to $250 million through the monetization of royalty rights for multiple gene therapies. This strategic move, involving partnerships with HealthCare Royalty and existing collaborations with pharmaceutical giants, aims to bolster RegenXBio's financial position and advance its diverse gene therapy portfolio.

Zolgensma Royalties and Pipeline Advancements

The cornerstone of this financial arrangement involves RegenXbio's continued monetization of royalty rights for Zolgensma, the Novartis-partnered spinal muscular atrophy gene therapy. Building on a previous $200 million deal in 2020, RegenXbio has once again tapped into the commercial success of Zolgensma to secure immediate funding.

In addition to Zolgensma, the agreement encompasses anticipated payments linked to two other gene therapies in RegenXbio's pipeline. One of these, RGX-121 for Hunter syndrome, is currently awaiting an FDA decision for approval. The other therapy included in the deal remains in development, showcasing RegenXbio's commitment to advancing multiple candidates simultaneously.

Strategic Partnerships and Financial Details

RegenXbio's deal with HealthCare Royalty, a firm specializing in acquiring drug royalties, is structured to provide immediate and potential future benefits. The company will receive an upfront payment of $150 million, with an additional $50 million due by April 2027, contingent on Zolgensma meeting sales milestones. A final $50 million installment is subject to mutual agreement between the parties.

This influx of capital is expected to extend RegenXbio's cash runway into early 2027, providing crucial financial stability as the company navigates the complex landscape of gene therapy development and commercialization. Mitchell Chan, RegenXbio's Chief Financial Officer, emphasized the strategic importance of this financing, stating, "This strategic financing brings future potential funds forward and extends our runway beyond multiple meaningful milestones."

Expanding Collaborations and Pipeline Progress

While the HealthCare Royalty deal takes center stage, RegenXbio's broader collaborative efforts continue to bear fruit. A recent $110 million upfront deal with Nippon Shinyaku, announced in January, grants the Japanese firm commercialization rights for RGX-121 and RGX-111 (a phase 2-stage therapy for Hurler syndrome) in the U.S. and Asia. This partnership could yield up to $700 million in additional milestone payments and double-digit royalties on net sales.

RegenXbio is also maintaining focus on other key pipeline candidates, including the AbbVie-partnered eye disease gene therapy surabgene lomparvovec (ABBV-RGX-314), which is notably excluded from the HealthCare Royalty agreement. The company's diverse portfolio spans rare diseases and retinal disorders, positioning RegenXbio as a leader in the gene therapy space.

As RegenXbio approaches potential product launches and pivotal data readouts, this latest financial maneuver underscores the company's strategy of leveraging non-dilutive capital to drive progress. With an extended cash runway and a robust pipeline, RegenXbio appears well-positioned to navigate the challenges and opportunities in the rapidly evolving field of gene therapy.
