SX-682 With Pembrolizumab for the Treatment of Metastatic or Recurrent Stage IIIC or IV Non-Small Cell Lung Cancer
Study Details
Study Description
Brief Summary
This phase II trial tests whether CXCR1/2 inhibitor SX-682 (SX-682) with pembrolizumab works to treat patients with stage IIIC or IV non-small cell lung cancer that has spread to other parts of the body (metastatic) or that has come back (recurrent). SX-682 is a drug that binds to receptors on some types of immune and cancer cells, inhibiting signaling pathways, reducing inflammation, and allowing other types of immune cells to kill and eliminate cancer cells. Pembrolizumab is a monoclonal antibody that binds to a receptor called PD-1 that is found on the surface of T-cells (a type of immune cell), activating an immune response against tumor cells. Giving SX-682 in combination with pembrolizumab may be more effective at treating patients with metastatic or recurrent non-small cell lung cancer than giving these treatments alone.

Detailed Description
OUTLINE:
Patients receive SX-682 orally (PO) and pembrolizumab intravenously (IV) on study. Patients also undergo biopsy and positron emission tomography (PET)/computed tomography (CT) or CT at screening and on study and undergo magnetic resonance imaging (MRI) and collection of blood samples at screening, throughout the study, and during follow up.

Outcome Measures
Primary Outcome Measures
- Best objective response rate [Up to 6 years]
Response is defined as a complete response (CR) or partial response (PR) as best objective response. For the primary analyses, binary proportions will be estimated along with 90% confidence intervals (consistent with 1-sided 5% level testing).
Secondary Outcome Measures
- Response rate within cohorts [Up to 6 years]
Evaluated within the cohorts separately (>= 50% and 1-49% PD-L1 tumor proportion score). Will evaluate the response rate within the cohorts separately. Within each cohort, the response rates and associated 80% confidence intervals will be estimated.
- Disease control rate [Up to 6 years]
- Duration of response [Date of first documentation of confirmed response (CR or PR) to date of first documentation of progression, assessed up to 6 years]
Will be estimated using the method of Kaplan-Meier. Confidence intervals about medians will be estimated using the Brookmeyer-Crowley method.
- Progression-free survival [Date of study registration to date of first documentation of progression, assessed up to 6 years]
Will be estimated using the method of Kaplan-Meier. Confidence intervals about medians will be estimated using the Brookmeyer-Crowley method.
- Overall survival [Date of study registration to date of death due to any cause, assessed up to 6 years]
Will be estimated using the method of Kaplan-Meier. Confidence intervals about medians will be estimated using the Brookmeyer-Crowley method.
- Frequency and severity of adverse events [Up to 6 years]
Toxicity frequencies will be estimated with 95% confidence.
