Regulatory Roadblocks and Enrollment Surges: Key Contradictions from REGENXBIO's Q4 2024 Earnings Call

These are the key contradictions discussed in REGENXBIO's latest 2024Q4 earnings call, specifically including: Non-dilutive Financing Options and AbbVie Milestone, DMD Enrollment Pace and Patient Interest, and Regulatory Discussions with FDA:



Regenerative Gene Therapy Pipeline Progress:
- REGENXBIO submitted its first BLA for RGX-121, an onetime treatment for Hunter syndrome, marking a significant milestone in its pipeline development.
- This progress was driven by the positive data from the pivotal trial, which met its primary endpoint and demonstrated decreased CSF levels of heparan sulfate, leading to a potential FDA approval in the second half of 2025.

Duchenne Muscular Dystrophy Program Advancement:
- The pivotal study for RGX-202 is advancing rapidly, with nearly half of the enrollment completed and anticipated completion this year.
- This progress is attributed to the strong interest from patients and families, supported by positive functional data and robust microdystrophin expression, along with a proactive immune suppression regimen.

Retinal Program and Global Partnership:
- AbbVie RGX-314 is advancing in late-stage studies, with data from pivotal trials expected in 2026 for wet AMD and diabetic retinopathy.
- The global partnership with AbbVie is a significant enabler for large commercial opportunities, with ongoing favorable regulatory interactions and a potential pivotal study in diabetic retinopathy expected to start this year.

Financial Position and Non-dilutive Financing:
- REGENXBIO ended the year with $245 million in cash and cash equivalents, with a cash runway into the second half of 2026.
- The company's financial position is strengthened by potential non-dilutive financing sources, including milestone payments from Nippon Shinyaku and AbbVie, and the monetization of the Priority Review Voucher, which could extend the cash runway beyond 2026.
