Summary

TNM-001 is an investigational human IgG1 monoclonal antibody (mAb) currently in clinical development for the prevention of respiratory syncytial virus (RSV) infection. Notably, there are no currently approved vaccines or specific antiviral therapies for RSV in China. TNM-001, developed by Trinomab, represents the first domestic long-acting human anti-RSV antibody drug to be independently developed in China. Preclinical studies have demonstrated that TNM-001 exhibits potent RSV neutralising activity and possesses a favourable pharmacokinetic profile, with an extended half-life to provide protection throughout the entire RSV epidemic season. This novel mAb may provide an additional therapeutic option for the prevention of RSV infection in infants and children worldwide.

Approval status

Investigational New Drug (IND) Application of TNM001 injection was approved by China NMPA in July and US FDA in November of 2021.

Drug structure

Scale-up and manufacturing prospects

Scale-up prospects

General manufacturing requirements and production scale-up for therapeutic monoclonal antibody (mAb) products is primarily focused on pharmacokinetic suitability, formulation stability and the overall maintenance of product quality. Industrial bioprocessing steps can also potentially introduce additional challenges regarding mAb formulation viscosity and aggregation propensity.

Tentative equipment list for manufacturing

Industrial bioreactor vessel with a production volume capacity of between 5-25kL. Continuous disc stack centrifuges for bioreactor harvesting with subsequent membrane and depth filtration for supernatant clarification. Recombinant protein-A chromatography or other suitable affinity capture apparatus followed by two chromatographic polishing steps such as cation- and anion-exchange. Ultrafiltration membrane system to concentrate and formulate the final product.

Manufacturing

MAbs are highly dependent on their structural, chemical and conformational stability for biological activity. Chemical degradation of mAbs during manufacture can lead to the generation of product variants and complex impurity profiles resulting from a wide range of processes, including: N-linked glycosylation, isomerisation, fragmentation, deamidation, oxidation and C-terminal lysine clipping. Additionally prior to packaging, the final product requires close monitoring for the presence of residual contaminants such as endotoxins and pro-inflammatory peptidoglycans.

Specific analytical instrument required for characterization of formulation

Formulation characterisation steps for therapeutic mAb products include (but are not limited to): (1) Identification of post-translational modifications using ion-exchange chromatography and capillary isoelectric focusing, (2) Measurement of concentration dependent aggregation rates via thermal differential scanning calorimetry, sub-visible particle quantitation and size-exclusion chromatography, and (3) Antibody clipping and fragmentation detection by capillary electrophoresis.
