Description: Serabelisib (also known as MLN1117, INK1117, and TAK-117) is an orally bioavailable inhibitor of the class I phosphoinositide 3-kinase (PI3K) alpha isoform with potential antineoplastic activity. PI3K alpha inhibitor INK1117 selectively inhibits PI3K alpha kinase, including mutations of PIK3CA, in the PI3K/Akt/mTOR pathway, which may result in tumor cell apoptosis and growth inhibition in PI3K alpha-expressing tumor cells. By specifically targeting class I PI3K alpha, this agent may be more efficacious and less toxic than pan-PI3K inhibitors.

Additional Information

INK1117 has demonstrated significant efficacy in several PI3Kα mutant-specific preclinical mouse xenograft tumor models. Moreover, daily oral administration of INK1117 inhibited tumor growth in a dose-dependent manner with a predicted PK/PD relationship, was well tolerated at a range of efficacious doses, and exhibited several differentiating features from less selective inhibitors that target the PI3K/Akt/mTOR pathway.  A Phase I dose escalation study is underway to evaluate the safety, tolerability and pharmacokinetics of single-agent INK1117 in patients with advanced solid malignancies who have tumors characterized by the presence of a PIK3CA mutation.   (source:
