What is ISMO?
ISMO (Trade name: Asaritinib) is a targeted tyrosine kinase inhibitor developed by companies such as Gilead Sciences and other pharmaceutical entities. It is primarily designed to treat certain cancers by inhibiting the fibroblast growth factor receptor 1 (FGFR1) pathway, which is involved in tumor growth and progression.
Current Development Status
ISMO is in phase 2 clinical trials for various indications, including:
- Lung adenocarcinoma with FGFR1 amplification
- Bladder cancer
- Other solid tumors
No approvals from regulatory authorities (FDA, EMA) have been granted as of Q1 2023. Its commercial viability depends on trial outcomes and subsequent regulatory approvals.
