A Phase I Study of FCN-411 in Advanced Non-small Cell Lung Cancer Chinese Patients With EGFR Positive Mutation

Study Overview
=================
Brief Summary
-----------------
This phase I trial with dose-escalation stage and dose-expansion stage is the first-in-human study of FCN-411, a drug being developed for treatment of advanced cancers. The initial purpose of the study is to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of FCN-411 monotherapy in EGFR-positive mutation non-small cell lung cancer chinese patients. The study will also provide early information on how the body handles the drug (pharmacokinetics) and on the anti-tumor activities of FCN-411.

Detailed Description
-----------------
This is a multicenter, open, single arm phase I clinical trial to explore the dose of FCN-411 in advanced lung cancer patients with disease progression after standard treatment or unsuitable for standard treatment and to expand the dose in advanced NSCLC patients who failed EGFR-TKI treatment. During the screening period, patients need to provide tumor tissue/ blood samples collected after their disease progression for tumor biomarker detection. In this study, the safety, tolerance and pharmacokinetic characteristics of FCN-411 were observed by dose escalation study and dose expansion study, and the antitumor activity of FCN-411 was preliminarily evaluated to determine maximal tolerated dose (MTD) and recommended phase 2 dose (RP2D). The phase I dose escalation study includes two stages: single dose stage and continuous dose stage; phase I dose expansion study is continuous dose administration. The research cycle is made up of screening period (day-28-day-1), single administration period (7 days), continuous administration period (every 21 days, evaluated every 6 weeks, until disease progression, intolerable toxicity, death, decision of the investigator or voluntary withdrawal of the patient), end of treatment, EOT) visit, safety follow-up (30 days after the last administration), survival follow-up (survival follow-up every 3 months from the safety follow-up until the end of the study). The end of study is one year after the first administration of the last enrolled patient or the end of treatment (whichever is earlier).

Design Details

Primary Purpose: Treatment
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Interventional Model Description: In the dose escalation cohort of FCN-411, the dose will be escalated from 4 mg, 8 mg, 16 mg, 24 mg to 32 mg. The MTD will be expanded to ascertain the RP2D.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Dose escalation cohort of FCN-411<br>FCN-411 will be orally administrated at five sequential dose levels, which are 4 mg, 8 mg, 16 mg, 24 mg, and 32 mg. Patients must be diagnosed with locally advanced or metastatic NSCLC who have progressed following prior therapy with an EGFR TKI agent (+/- additional chemotherapy regimens). Participants will receive FCN-411 monotherapy once daily (QD) for sequential 21-day cycles. | Drug: FCN-411 Dose-escalation<br>* FCN-411 is a pan EGFR inhibitor, which has strong activity against wild type (WT), HER2, HER4 and EGFR sensitive mutations (including but not limited to T790M and L858R mutation). FCN-411 shows significant antitumor activity in a dose-dependent manner in in vivo models of lung cancer, esophageal cancer and pharyngeal squamous cell carcinoma mediated by EGFR.<br>* Other names: EGFR-TKI;|
