Pilot Study of Abequolixron (RGX-104) and Durvalumab in Lung Cancer

Study Overview
=================
Brief Summary
-----------------
Non-Small Cell Lung Cancer (NSCLC) is one of the deadliest types of cancer. In lung cancer patients with a tumor that can be removed by surgery, adjuvant chemotherapy increases survival. Neoadjuvant therapy may have advantages such as, it may be more tolerable prior to surgery, earlier treatment may be more efficacious, and it can provide an indication of treatment response. Neoadjuvant treatment can provide pre- and post-treatment specimens for correlative analysis to better understand mechanisms of action and resistance. This pilot study will investigate the effects of neoadjuvant durvalumab plus platinum doublet chemotherapy and neoadjuvant durvalumab plus platinum doublet chemotherapy in combination with abequolixron (RGX-104), an LXR/ApoE agonist, in subjects with NSCLC who are scheduled to undergo surgical resection as part of their standard of care. The purpose of this study is to study how well using a combination of durvalumab, platinum doublet chemotherapy (carboplatin/abraxane or carboplatin/pemetrexed), and abequolixron treats non-small cell lung cancer before surgery. Durvalumab (a type of immunotherapy) and platinum doublet chemotherapy are drugs that are individually approved for use during the treatment of cancer. FDA (Food and Drug Administration) has not approved the combined use of these drugs in treating non-small cell lung cancer. Abequolixron is not FDA approved for the treatment of cancer.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Feasibility of surgery | Feasibility will be evaluated as the delay time between the completion of neoadjuvant therapy and surgery. A failure of feasibility will be defined as a delay in the planned surgery of more than 42 days (surgical delay of 35 days, plus 7 days for scheduling). | Up to 120 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Toxicities | Toxicities related to study treatment therapy will be classified and graded according to The NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE v5.0). NCI-CTCAE v5.0 is a descriptive terminology that can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local, or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE. | Up to 1 years after surgery |
