This is a Phase I clinical study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamic, and preliminary antitumor activity of ZX-4081. Patient enrolment is scheduled to initiate in the fourth quarter of 2021 in the USA. ZX-4081 is the second FDA IND approval received by Zenshine Pharma.

About ZX-4081
ZX-4081 is a highly selective and potent PI3Kγ inhibitor. Recent studies found that PI3Kγ is a molecular switch that governs immune suppression  and promotes immunosuppressive myeloid cell polarization during tumor growth and metastasis. Inhibition of PI3Kγ overcomes resistance to immune checkpoint blockade therapy. ZX-4081,as the most selective and potent PI3Kγ inhibitor up to date, has shown favorable pharmacokinetic profile in pre-clinical studies and efficacy  in solid-tumor-bearing mouse models. ZX-4081  is potentially one ofthe first-in-class PI3Kγ inhibitors for the treatment of solid tumors, either as single agent or in combination with other anticancer agents.
