* Acquisition expands GSK's respiratory pipeline adding AIO-001, a phase II-ready, long-acting antibody targeting the clinically validated TSLP pathway
* AIO-001 could redefine the standard-of-care with dosing every six months
* AIO-001 has potential to expand GSK's respiratory biologics portfolio to reach a broader portion of asthma patients
The acquisition provides GSK with access to
Targeting the TSLP pathway addresses a key driver of the inflammatory response in major allergic and inflammatory diseases. TSLP is a clinically validated target in the treatment of asthma regardless of biomarker status. Early studies of AIO-001 have shown initial safety, tolerability, pharmacokinetics, and biological activity in healthy volunteers and asthma patients. Additionally, AIO-001 has potential to be administered every six months due to its enhanced potency and half-life extension technology, which could redefine the standard-of-care.
GSK has an industry-leading portfolio of marketed and investigational medicines to address a range of respiratory diseases, including biologics aimed at treating the subset of asthma patients with high levels of eosinophils or high T2 inflammation. With AIO-001, GSK's respiratory portfolio could provide the option of a biologic to a broader portion of the 315 million patients living with asthma regardless of biomarker status and including those with low T2 inflammation.2

About AIO-001
AIO-001 is a novel monoclonal antibody with potential for longer dosing intervals, such as every 6 months, due to its half-life extension and differentiated potency. AIO-001 binds to the human thymic stromal lymphopoietin (TSLP) ligand to inhibit TSLP signalling. TSLP has a validated, central role in driving inflammation, including in asthma.
About GSK in respiratory
