Clinical Trial 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.

Description:

Following completion of screening procedures and confirmation of patient eligibility, the participants are enrolled in the study. The study treatment begin on Cycle 1, Day 1 with the first administration of EGF816. A treatment cycle is defined as 28 days. Oral EGF816 is administered once daily on a continuous schedule until patient experiences unacceptable toxicity, progressive disease (PD), and/or treatment is discontinued at the discretion of the investigator, patient withdrawal of consent, or due to any other reasons. Treatment with EGF816 may be continued beyond RECIST 1.1 defined PD, if, in the judgment of the investigator, there is evidence of clinical benefit and the patient wishes to continue with the study treatment.

Intervention

Drug:
• EGF816
EGF816 will be dosed once daily. On the first day of each treatment cycle, the patient receives an adequate drug supply for self-administration at home. The investigator will instruct the patient to take EGF816 exactly as prescribed.
