WX-0593 Combined With Concurrent Chemoradiotherapy in Unresectable Locally Advanced NSCLC

Summary

The aim of this trial is to evaluate the safety of WX-0593 combined with concurrent chemoradiotherapy in unresectable, locally advanced non-small cell lung cancer (NSCLC) with activating mutation of ALK or ROS1. This trial consists of two parts. In Part 1, approximately 8 patients will be included and receive WX-0593 maintenance until disease progression or unacceptable toxicity. In Part 2, approximately 32 patients will be included and receive WX-0593 monotherapy for 1-2 cycles and subsequently with concurrent chemoradiation, followed by WX-0593 maintenance until disease progression or unacceptable toxicity.

Eligibility

* Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1;
* Has at least one evaluable lesion (according to RECIST 1.1);
* Have adequate pulmonary function test as a forced expiratory volume in 1 second (FEV1) \>50% of predicted normal volume and carbon monoxide lung diffusing capacity (DLCO) \>40% of predicted normal value;
* Have adequate organ and marrow function;
* If participant is a woman of childbearing potential (WOCBP), must agree to follow the contraceptive guidance from written informed consent until at least 180 days after the last dose of study treatment. The female participant should have negative serum pregnancy test within 7 days prior to the first dose of study drug, and not breastfeeding;

* Mixed small cell and non-small cell lung cancer histology;
* Has received prior therapy with any ALK TKI;
* Has a history of extensive diffuse/bilateral interstitial fibrosis, or grade 3 or 4 pulmonary fibrosis or interstitial lung disease prior to the first dose of study drug.

Has a known history of active tuberculosis; severe infection within 4 weeks prior to study entry;
