- Registration Number
- NCT06731270
- Lead Sponsor
- Emory University
- Brief Summary
This phase II trial tests how well diclofenac works in treating patients non-small cell lung cancer (NSCLC) that may have spread from where it first started (primary site) to other places in the body (metastatic) on single agent immunotherapy. Diclofenac, a type of non-steroidal anti-inflammatory (NSAID), blocks the body's production of a substance that caus...
- Detailed Description
PRIMARY OBJECTIVE:
I. To evaluate the clinical benefit rate of concomitant diclofenac potassium (diclofenac) and single agent checkpoint blockade.
SECONDARY OBJECTIVES:
I. To evaluate the safety and tolerability of concomitant diclofenac and single agent checkpoint blockade.

- Primary Outcome Measures
Name Time Method Clinical benefit rate (CBR) At 12 weeks CBR will be defined as complete response, partial response, and/or stable disease. Clinical response will be assessed using Response Evaluation Criteria for Solid Tumors (RECIST) 1.1 criteria. Clinical benefit rate will be reported as a proportion, with an exact 80% confidence interval estimated using the Clopper-Pearson method.
- Secondary Outcome Measures
Name Time Method Incidence of adverse events (AEs) Up to 30 days after last dose of study treatment AEs severity will be assessed using National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Descriptive statistics will be reported, using frequencies and percentages for each toxicity.
Objective response rate (ORR) At 12 weeks ORR will be defined per RECIST 1.1. ORR will be reported as a proportion, with an exact 95% confidence interval estimated using the Clopper-Pearson method.
Progression-free survival (PFS) From initiation of treatment to progression or death up to 1 year PFS will be determined by RECIST 1.1. PFS will be estimated using the Kaplan-Meier method, and a 95% confidence interval for median PFS will be estimated using the Brookmeyer-Crowley approach.
Overall survival (OS) From diagnosis to death from any cause up to 1 year OS will be estimated using the Kaplan-Meier method, and median OS will be calculated. A 95% confidence interval will be estimated using the Brookmeyer-Crowley approach.
Duration of response (DOR) From the date of first response to the date of the first progressive disease or death due to any cause up to 1 year DOR will be estimated using the Kaplan-Meier method, and median DOR will be calculated. A 95% confidence interval will be estimated using the Brookmeyer-Crowley approach.
