Recent phase 3 trials demonstrated modest improvements in durability, but failures that might be attributed to these strategies (conjugation and manufacturing processes) have occurred. Future drug development focuses on extending duration of action with implantable reservoirs (ranibizumab port delivery system), sustained release devices (tyrosine kinase inhibitors), and gene therapy.

While current treatments for w-AMD have significantly advanced with the advent of anti-VEGF therapies, their limitations in terms of treatment burden and incomplete responses have spurred research into diverse alternative approaches. These innovative strategies offer hope for improving patient outcomes and reducing healthcare burdens, suggesting a promising future for w-AMD management.

Journal: Investigational drugs in clinical trials for macular degeneration.

Complement inhibitors (Pegcetacoplan and Avacincaptad pegol) will likely obtain FDA approval but will serve to pave the way for combined complement and direct phagocytic inhibitors such as AVD-104.

Sustained-release anti-VEGF therapies include the ranibizumab Port Delivery System (in phase 3 studies), GB-102 (Phase 2b), OTX-TKI (phase 1), and Durasert (preclinical)...Genetic therapies in phase 1 studies include RGX-314 and ADVM-022, which introduce a viral vector that modifies the retina's cellular apparatus to create an anti-VEGF biofactory, potentially serving as a one-time treatment. Further investigation is warranted for drugs and delivery systems that hope to advance visual outcomes and reduce treatment burden of nAMD.

Characterization of Antibody Biopolymer Conjugate reveals superior biophysical properties compared to naked antibodies (Exhibit Hall: Posterboard# A0323) - Mar 9, 2020 - Abstract #ARVO2020ARVO_4917; Here, we present the biophysical characterization of KSI-301, a novel anti-VEGF ABC, which is currently in clinical testing for the treatment of retinal vascular diseases.Methods Intermolecular interactions of KSI-301 Conjugate or KSI-301 Protein (IgG only) were assessed by A2 (SEC-MALS) and KD (DLS) measurements at various pH and salt concentrations...These underlying biophysical properties may also contribute to the observed enhanced tissue penetration and improved ocular distribution seen for ABC. Altogether, our continuing studies demonstrate the ABC system is an important new platform with the potential to treat a wide array of retinal diseases.
