• Wave Life Sciences will pursue FDA accelerated approval for WVE-N531, an exon 53 skipping therapy for Duchenne muscular dystrophy, following positive Phase 2 trial results showing increased dystrophin production. • The experimental treatment demonstrated substantial improvements in muscle health with a statistically significant improvement in "time to rise" functional tests compared to historical controls through 48 weeks of treatment. • If approved, WVE-N531 could offer a potential monthly dosing regimen and become a new therapeutic option for approximately 8-10% of Duchenne patients with specific genetic mutations amenable to exon 53 skipping.

Adverum Launches Groundbreaking Phase 3 ARTEMIS Trial for One-Time Gene Therapy in Wet AMD

• Adverum Biotechnologies initiates ARTEMIS, the first-ever registrational intravitreal gene therapy trial for wet AMD, evaluating Ixo-vec against standard aflibercept treatment in 284 patients. • The innovative trial design includes both treatment-naïve and previously treated patients, comparing a single Ixo-vec injection to regular aflibercept dosing with a primary endpoint of non-inferior vision outcomes. • Current data shows 42% of wet AMD patients discontinue treatment after 2 years, highlighting the potential impact of Ixo-vec's one-time administration approach for long-term vision preservation.

Clearside's CLS-AX Phase 2b Trial Data Shows Promise in Treatment-Naïve AMD Patients

• New subgroup analyses from Clearside Biomedical's ODYSSEY Phase 2b trial provide strategic insights for upcoming Phase 3 program in neovascular age-related macular degeneration. • Data presented at the Angiogenesis 2025 meeting supports focusing on treatment-naïve patients and implementing specific visual acuity criteria for future trials. • The 36-week ODYSSEY trial employed a robust design, being randomized, double-masked, and active-controlled across multiple centers.

REGENXBIO and Nippon Shinyaku Partner to Advance Gene Therapies for MPS I and MPS II

• REGENXBIO and Nippon Shinyaku have entered an exclusive partnership to develop and commercialize RGX-121 for MPS II and RGX-111 for MPS I. • Nippon Shinyaku will lead commercialization in the U.S. and Asia, while REGENXBIO will continue to lead clinical development and manufacturing. • The agreement includes an upfront payment of $110 million to REGENXBIO, with potential milestone payments reaching up to $700 million. • RGX-121 and RGX-111 are AAV-based gene therapies designed to address the underlying enzyme deficiencies in MPS II and MPS I, respectively.

Focused Ultrasound Shows Promise in Alzheimer's Treatment

• A clinical trial using focused ultrasound to treat Alzheimer’s disease has shown promising results, marking a potential new direction in treating this debilitating condition. • The study, published in the Journal of Neurosurgery, highlights the noninvasive nature of focused ultrasound as a key advantage in Alzheimer's treatment. • Researchers are optimistic about the potential of this approach to offer a new therapeutic avenue for patients suffering from Alzheimer's disease. • Further research is needed to fully understand the long-term effects and optimal use of focused ultrasound in Alzheimer's treatment.

Arvinas Advances Vepdegestrant into Phase 3 Trials for Breast Cancer and Updates Pipeline Milestones

• Arvinas plans to initiate two Phase 3 trials in 2025 for vepdegestrant in ER+/HER2- metastatic breast cancer, one in the first-line setting with atirmociclib and another in the second-line setting with a CDK4/6 inhibitor. • Topline data from the Phase 3 VERITAC-2 monotherapy trial of vepdegestrant in second-line-plus ER+/HER2- metastatic breast cancer is anticipated in the first quarter of 2025. • Arvinas is set to present initial data from the Phase 1 trial of ARV-393 in B-cell lymphomas and file an IND application for a novel PROTAC KRAS G12D degrader in 2025. • Phase 1 trial with PROTAC LRRK2 degrader ARV-102 in patients with Parkinson’s disease has been initiated, with data expected to be presented in the first half of 2025.

Regenxbio Expands MPS I Gene Therapy Trial After Initial Data Review

Regenxbio has decided to expand its phase 1/2 trial for RGX-111, a gene therapy targeting mucopolysaccharidosis type I (MPS I), following promising initial data showing clinical activity.

• Sarepta Therapeutics' Elevidys demonstrates sustained benefits and disease stabilization in ambulatory Duchenne muscular dystrophy (DMD) patients, according to Phase 3 EMBARK trial results. • Crossover-treated patients showed a 2.34-point improvement on the North Star Ambulatory Assessment (NSAA) compared to matched external controls after 52 weeks of Elevidys treatment. • Patients treated with Elevidys in Part 1 of EMBARK maintained clinically meaningful improvements in NSAA, Time to Rise (TTR), and 10-meter walk/run (10MWR) at two years. • Muscle biopsies showed consistent micro-dystrophin expression, and MRI scans indicated minimal muscle pathology progression, reinforcing Elevidys's long-term efficacy and safety.

Sozinibercept Shows Promise in Improving Visual Outcomes for nAMD Patients

• Sozinibercept, a novel VEGF-C/D inhibitor, is under investigation for neovascular age-related macular degeneration (nAMD) to improve visual acuity beyond current VEGF-A therapies. • Phase 2b trials showed that sozinibercept combined with ranibizumab led to a statistically significant additional gain of 3.4 letters in BCVA compared to ranibizumab alone at 24 weeks. • Ongoing Phase 3 trials (ShORe and COAST) are evaluating sozinibercept in combination with ranibizumab or aflibercept, with potential regulatory filings planned after 12-month efficacy analysis. • Next-generation nAMD therapies like sozinibercept aim to target multiple pathways beyond VEGF-A to enhance vision and quality of life for patients, addressing the limitations of current treatments.

Cell Therapy and Targeted Therapies Dominate Oncology Advances in Early 2025

• The FDA issued a CRL for Atara Biotherapeutics' tabelecleucel due to third-party manufacturing issues, not efficacy or safety data, delaying potential approval for EBV+ PTLD. • EsoBiotec dosed the first patient in a trial for ESO-T01, an in vivo BCMA-directed CAR-T therapy for multiple myeloma, aiming for lower costs and simplified administration. • Obecabtagene autoleucel (obe-cel) gained FDA approval for relapsed/refractory B-cell precursor ALL, offering a less toxic CD19-directed CAR T-cell therapy option. • Arlocabtagene autoleucel (arlo-cel) shows promise in heavily pretreated relapsed/refractory multiple myeloma, eliciting a 48% complete response rate in phase 1 studies.
