LEN is commercially manufactured. Production scale up and manufacturing requirements for therapeutic mAbs are primarily related to formulation stability, pharmacokinetic suitability and maintenance of quality attributes. The industrial manufacture of high-concentration broadly neutralising antibody (bNAb) formulations for parenteral administration can introduce production challenges regarding aggregation propensity and formulation viscosity. Exploratory process optimisations such as bNAb co-formulation and multi-specific Ab composition have the potential to reduce overall manufacturing costs
Equipment for injectable: Stainless steel pharmaceutical reactors, glass-lined reactors, rotary evaporator (rotovap), flash chromatography columns, stainless steel autoclave, cooling bath, silica gel chromatography columns, vacuum distillation apparatus, simulated moving bed chromatography system, Chiralpak columns. 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.
Storage of injectable lenacapavir in borosilicate vials is contraindicated due to issues with chemical compatibility. Instead, it is recommended that vials are made from aluminosilicate glass. Biological activity of bNAbs is highly dependant on their chemical, conformational and structural stability. Reduced glycosylation of bNAbs during manufacture and chemical degradation processes such as deamidation can result in increased aggregation, loss of activity and diminished solubility. Degradation may occur at any stage throughout the manufacturing process.
Proton nuclear magnetic resonance (1H NMR), High-performance liquid chromatography (HPLC), Ultra-Performance Liquid Chromatography (UPLC). Formulation characterisation for single-entity bNAb production include capillary isoelectric focusing and ion-exchange chromatography for identification of post-translational modifications, subvisible particle quantitation, thermal DSC, size-exclusion chromatography for measurement of concentration dependent aggregation rates and capillary electrophoresis for antibody fragmentation and clipping.

Phase II
Active, not recruiting
Gilead Sciences
The goal of this study is to test the effectiveness, safety, and tolerability of the combination of broadly neutralizing antibodies (bNAbs) (teropavimab (TAB; GS-5423) and zinlirvimab (ZAB; GS-2872)) with lenacapavir (LEN) in virologically suppressed adults with HIV-1 infection. The purpose of this study is to evaluate the efficacy of switching to a regimen of LEN, TAB and ZAB, versus continuing on baseline oral antiretroviral therapy (ART) as determined by the proportion of participants with human immunodeficiency virus-1 (HIV-1) ribonucleic acid (RNA) ≥ 50 copies/mL at Week 26.

Unconfirmed virologic elevations of ≥ 50 copies/mL (transient detectable viremia, or "blip") prior to screening are acceptable. * Proviral phenotypic sensitivity to both teropavimab and zinlirvima
