A Phase 2 Exploratory Study of Erlotinib and SNDX-275 in Patients With Non-small Cell Lung Carcinoma Who Are Progressing on Erlotinib
Study Details
Study Description
Brief Summary
Preclinical studies have shown that SNDX-275 is able to reactivate the expression of EGFR, E-cadherin and ErbB3 expression. The combination of SNDX-275 with erlotinib (an EGFRi) in patients who are progressing on erlotinib will show measurable activity as evidenced by the disease control rate and with an acceptable safety profile.

Experimental: 2 "Erlotinib-nonresponsive" patients are those who either progressed immediately during treatment with erlotinib (i.e. after at least 1 full cycle of erlotinib treatment) or had an objective response or period of stable disease lasting less than 3 months. |
