FDA approves imatinib (Imkeldi), the first oral, liquid tyrosine kinase inhibitor for treating cancers like GIST, MDS, MPD, CML, and Ph+ ALL. Oral imatinib offers precise dosing and convenience, benefiting patients with swallowing difficulties or needing tailored dosing. It can be used from age 1, addressing significant needs in CML, MDS/MPD, GIST, and ALL patients. Imatinib targets the BCR-ABL anomaly, showing efficacy in older patients, especially with chemotherapy. Safety in pediatric Ph+ ALL is yet to be established, and monitoring is crucial due to potential risks like edema and hematologic toxicity.
