A Phase I/II, Multicenter, Open-label Study of EGFRmut-TKI EGF816, Administered Orally in Adult Patients With EGFRmut Solid Malignancies

Summary

This is a Phase I/II, multi-center, open-label study, composed with a Phase I part (dose-escalation phase) followed by a Phase II part (expansion phase). The dose escalation phase was designed to determine as primary objective the maximum tolerated dose (MTD) or recommended Phase II dose (RP2D) of EGF816 monotherapy in adult subjects with locally advanced (stage IIIB) or metastatic (stage IV) NSCLC harboring specific EGFR mutations. Patients may have or not have received prior lines of antineoplastic therapy. An adaptive Bayesian Logistic Regression Model (BLRM) employing the escalation with overdose control (EWOC) principle will be used during the dose escalation part for dose level selection and MTD recommendation. The primary objective of the Phase II part is to estimate antitumor activity of EGF816 as measured by overall response rate (ORR) determined by Blinded Independent Review Committee (BIRC) assessment in accordance to RECIST 1.1.
