Increase Downstream Productivity and Decrease Costs with Multi-column Continuous Chromatography
Multi-column continuous chromatography (MCC) offers significant economic advantages over traditional batch methods for the purification of monoclonal antibodies (mAbs), including increased resin capacity utilization, smaller columns, reduced buffer consumption, and faster processing time. For mAb productivity, the Protein A capture step is a primary target to apply MCC due to its high cost, which is driven even higher as improvements in upstream processing have produced a steady increase in mAb titers. The multi-column continuous chromatography method has demonstrated that mAb productivity can be increased by 400 to 500% compared to batch-mode.

Artiva Biotherapeutics will present data on AlloNK, an allogeneic, non-genetically modified NK cell therapy given with rituximab, in refractory rheumatoid arthritis, Sjögren disease and systemic sclerosis at ACR Convergence 2026, ahead of a planned phase 3 trial in rheumatoid arthritis.
Novartis has secured an exclusive worldwide license to ABO2203, Abogen's investigational mRNA-encoded CD19xCD3 T-cell engager designed to produce the bispecific inside the body to reset B cells in autoimmune disease. The agreement also includes options on other programs built on Abogen's RNA platform.
Former FDA oncology reviewer Paz Vellanki, MD, PhD, of Precision for Medicine, discusses how CDER's ARC program supports novel end points such as ctDNA for rare diseases and why sponsors should engage FDA early.
Following an FDA meeting, Wave Life Sciences plans a single 2-year registrational trial of WVE-006, its GalNAc-conjugated RNA editing oligonucleotide for alpha-1 antitrypsin deficiency, with a 1-year interim analysis that could support accelerated approval based on biomarkers.
