Phase II Study of Erlotinib With or Without Hydroxychloroquine in Patients With Previously Untreated Advanced NSCLC and EGFR Mutations

The purpose of this research study is to learn if adding hydroxychloroquine (HCQ) to erlotinib helps treat non-small cell lung cancer (NSCLC). Another goal of this research study is to learn more about NSCLC and how it may respond to study treatment. Erlotinib (Tarceva) is a type of drug called a tyrosine kinase inhibitor (TKI). TKIs block a protein called the epidermal growth factor receptor (EGFR). EGFR may control tumor growth and tumor cell survival. However, although TKI drugs can work for some lung cancer patients for a period of time, eventually the tumor finds a way to resist or counteract the TKI treatment and it begins to grow again. Hydroxychloroquine (HCQ) is a drug approved by the FDA for treating malaria, rheumatoid arthritis, and several other diseases. Laboratory research suggests that when HCQ is given with a TKI, it may help delay or prevent TKI resistance from developing.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.

Phase: Phase 2


Ages Eligible For Study:

18 Years - N/A

Inclusion Criteria

- Pathologically confirmed diagnosis of non-small cell lung cancer - Stage IV disease by the American Joint Committee on Cancer/IASLC 7th edition proposed edition staging criteria - An EGFR sensitizing mutation must be detected in tumor tissue. Specifically, patients harboring the most common mutations, deletions in exon 19 or the L858R mutation in exon 21 are eligible. Presence of the known resistance mutation T790M as detected by direct tumor sequencing is not allowed. Other rare EGFR mutations may be eligible after discussion with the overall principal investigator - Age equal to or greater than 18 years - Measurable disease by RECIST criteria, defined as the presence of at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as 10mm or greater with spiral CT scan - ECOG Performance status of 0, 1 or 2 - Since prior radiation or surgery, 14 days or more must have elapsed before starting protocol treatment - No prior treatment with erlotinib, gefitinib, or other small molecule EGFR-TKIs. Prior treatment in the adjuvant setting is allowed if at least 1 year has elapsed since TKI course. - Adequate organ function as outlined in the protocol - Patients must undergo a screening eye exam to obtain approval for HCQ treatment, which establishes the absence of baseline conditions include macular degeneration, visual field changes, other retinal disease, and cataracts that interfere with required funduscopic examinations - No G6PD deficiency, as HCQ may cause hemolysis in patients with G6DP
