1.Global RET Inhibitors Market

RET activating mutations appear in various cancer types
According to businesswirereports, global market projection of RET inhibitor is >$1.5B, with an absolute growth of 3900% (2020-2026).
The sales of 1^st-gen selective RET inhibitor( Pralsertinib and Selpercatinib) were$302M for 2023 and exceeding $400M for 2024

2. Design strategy

Many multikinase inhibitors (MKIs) have received clinical approval for the treatment of malignancies with RET alterations
However, their effectiveness has often been suboptimal, primarily due to a lack of specificity and a high incidence of drug-related toxic effects, necessitating dose reduction, treatment interruption, or discontinuation
Mutational resistance to 1^st-gen inhibitors have emerged in clinical settings
Most of drug developmenthas focused on 1^st gen inhibitors which can’t address the resistance issue, only a few are developing 2^nd gen inhibitors
New 2^nd-gen RETi is urgently needed to improve patient outcomes

Accelerated by AI, 2 potent inhibitors (<10nM) were identified from the first round of 12 compounds
Strong potency and efficacy that overcome drug resistance succumbed by 1^stgen RET inhibitors
