NEW YORK--(BUSINESS WIRE)-- Neurogene Inc. (Nasdaq: NGNE), a clinical-stage company founded to bring life-changing genetic medicines to patients and families affected by rare neurological diseases, today announced fourth quarter and full year 2024 financial results and highlighted recent corporate updates.

“We believe 2024 was a year of significant progress for our NGN-401 Phase 1/2 trial in Rett syndrome, as we reported encouraging interim efficacy data and NGN-401 was generally well-tolerated at the 1E15 vg dose in a pediatric cohort,” said Rachel McMinn, Ph.D., Founder and Chief Executive Officer of Neurogene. “We remain on track to provide an update on the registrational trial plans in the first half of 2025, and as we look ahead to the second half of 2025, we plan to share additional interim clinical data from the Phase 1/2 trial, including from our 11 years and older cohort.”

Fourth Quarter 2024 and Recent Highlights, and Anticipated Milestones

Phase 1/2 Trial of NGN-401 Gene Therapy for Treatment of Rett Syndrome

NGN-401 is currently being evaluated in an open-label Phase 1/2 trial. Key updates include:

• Protocol amended and submitted to U.S. Food and Drug Administration (FDA) with the 1E15 vector genomes (vg) dose for all future participants in the trial, and enrollment is ongoing; 1E15 vg is the dose Neurogene expects to evaluate in a future registrational trial of NGN-401 based on positive interim efficacy results presented in November 2024
• Expanded the age range in the trial to evaluate NGN-401 in a broader population, including ages > 11 years in the older pilot cohort (n=3), from the previous design of > 16 years; the pilot cohort is in addition to the 4 to 10 years cohort (n=8)
• Previously shared the Company gained alignment with the U.S. Food and Drug Administration (FDA) on chemistry, manufacturing and controls (CMC) scale-up plans to support NGN-401 potential commercial launch and potency assay strategy for the program
• Remains on track to provide a regulatory update on registrational trial plans in the first half of 2025
• Continues to expect to report additional interim clinical data from the Phase 1/2 trial in the second half of 2025, including additional participants expected to be dosed during the first half of the year
• Announced today it has received Priority Medicines (PRIME) designation by the European Medicines Agency (EMA); medicines are eligible for PRIME if they demonstrate the potential to address an unmet medical need by showing a meaningful improvement of clinical outcomes

Fourth Quarter and Full Year 2024 Financial Results

• Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities as of December 31, 2024 were $312.4 million and are expected to provide runway into the second half of 2027, which would allow for the completion of enrollment of a future registrational trial for NGN-401 for Rett syndrome, CMC scale-up to support NGN-401 registrational activities and further development of Neurogene’s EXACT™ gene therapy pipeline.
• Research & Development (R&D) Expenses: R&D expenses were $15.3 million and $60.9 million for the three and twelve months ended December 31, 2024, respectively, compared to $12.2 million and $44.4 million for the three and twelve months ended December 31, 2023, respectively. The increase in R&D for the twelve months ended December 31, 2024 was primarily driven by an increase in Rett syndrome clinical trial costs, employee-related expenses due to an increase in headcount, and preclinical costs related to Neurogene’s EXACT gene therapy pipeline.
• General & Administrative (G&A) Expenses: G&A expenses were $6.2 million and $22.6 million for the three and twelve months ended December 31, 2024, respectively, compared to $2.5 million and $11.2 million for the three and twelve months ended December 31, 2023, respectively. The increase in G&A expenses for the twelve months ended December 31, 2024 was primarily driven by an increase in employee-related expenses due to an increase in headcount, professional fees, and office-related and other corporate expenses.
• Net Income and Net Loss: Net loss was $19.5 million for the three months ended December 31, 2024, and $75.1 million for the twelve months ended December 31, 2024, respectively, compared to net income of $2.4 million and net loss of $36.3 million for the three and twelve months ended December 31, 2023, respectively. Net income for the twelve months ended December 31, 2023 included a one-time $16.4 million bargain purchase gain related to the reverse merger.
