Investigational thymic stromal lymphopoietin inhibitors for the treatment of asthma: a systematic review.

TSLP contributes to airway inflammation, making it a pivotal therapeutic target. Ecleralimab, an inhaled antibody fragment antigen binding, shows promising evidence in enhancing efficacy and reducing systemic adverse events. SAR443765, with its NANOBODY® formulation and bispecific inhibition of TSLP and IL-13, offers improved tissue penetration and efficacy. The mAB TQC2731 exhibits high in vitro bioactivity, and the strength of the mAb UPB-101 is to act against the TSLP receptor. Some studies include mild and moderate asthma patients, suggesting the potential for extending biological therapy to non-severe patients. This systematic review highlights the potential of TSLP inhibitors as valuable additions to asthma treatment, even in milder forms of the disease. Future research and cost-reduction efforts are needed to expanding access to these promising therapies.
