Targeted Therapies in Infantile Hemangiomas and Vascular Malformations: From β-Blockers to PI3K/AKT/mTOR Inhibitors. (PubMed, J Cell Mol Med)
The discovery that the non-selective beta-blocker propranolol induces rapid regression of proliferating IHs established the first widely adopted systemic pharmacologic therapy in vascular anomaly care and provided a clinical proof-of-concept that targeting lesion-specific endothelial biology can alter disease course. In parallel, recurrent somatic variants affecting PI3K/AKT/mTOR (e.g., PIK3CA, TEK/TIE2, AKT1) and RAS/MAPK (e.g., KRAS, NRAS) signalling have reframed many malformations as mosaic disorders amenable to targeted inhibition with agents such as sirolimus, alpelisib, AKT inhibitors and MEK inhibitors. This review synthesizes translational mechanisms, clinical evidence and safety considerations for beta-blockers and emerging targeted therapies, emphasizing lesion phenotype, timing of intervention and molecular stratification as determinants of response. We highlight current limitations, including toxicity, durability and pathway escape, and outline future directions for precision therapy and genotype-guided trial design in vascular anomalies.

Alpelisib and Fulvestrant in PIK3CA-mutated hormone receptor-positive HER2-negative advanced breast cancer included in the German PRAEGNANT trial. (PubMed, Breast Cancer Res Treat)
This prospective real-world analysis shows slightly shorter median PFS and OS times compared with the pivotal trials. Patients in our analyses received alpelisib in later therapy lines, which may explain the poorer outcome.

Model-Based Patient Selection and Dosing Strategies for HRAS and PIK3CA Dysregulated HNSCC: A QSP Model for Alpelisib and Tipifarnib Combination. (PubMed, Clin Pharmacol Ther)
Global sensitivity analysis identified compensatory feedback, tumor proliferation rate, and PI3K-mTOR crosstalk as key determinants of tumor response. This novel QSP application exemplifies an innovative bottom-up modeling approach to support patient selection and dosing strategies for future clinical studies.
