Naloxegol in Treating Patients With Stage IIIB-IV Non-small Cell Lung Cancer

Phase 2

Terminated

Conditions: Stage IIIB Non-Small Cell Lung Cancer
Stage IV Non-small Cell Lung Cancer

Interventions: Drug: Naloxegol
Other: Placebo
Other: Laboratory Biomarker Analysis
Other: Quality-of-Life Assessment

Registration Number: NCT03087708

Lead Sponsor: Alliance for Clinical Trials in Oncology

Brief Summary: This randomized pilot clinical trial studies the side effects and best dose of naloxegol and to see how well it works in treating patients with stage IIIB-IV non-small cell lung cancer. Naloxegol may relieve some of the side effects of opioid pain medication and fight off future growth in the cancer.

Detailed Description: PRIMARY OBJECTIVES:

I. To determine feasibility and safety of long-term administration of two doses of a peripheral opioid receptor antagonist in patients with advanced non-small cell lung cancer (NSCLC) receiving first-line systemic therapy.

SECONDARY OBJECTIVES:

I. To explore whether patients randomized to one or both of the two study drug arms have less decline in health-related quality of life (HRQoL) than patients randomized to placebo.

II. To estimate the difference in the pain levels and opioid/non-opioid analgesic requirements between patients receiving naloxegol or placebo.

III. To estimate the difference in the adverse peripheral effects of opioids (e.g. constipation, nausea/emesis, dry mouth and urinary retention) between patients receiving naloxegol or placebo.

IV. To explore whether there is a signal that naloxegol may be associated with longer progression-free survival (PFS) and overall survival (OS).

V. To evaluate the difference in discontinuation rate of systemic therapy due to adverse events (AEs) and deaths attributable to systemic therapy.

After completion of study treatment, patients are followed up every 3 months.

Secondary Outcome Measures

Name	Time	Method
Change in Trial Outcome Index	Baseline to 6 months	Health-related quality of life scores at each timepoint and changes in scores between 6 months and baseline will be summarized by mean standard deviation, median (inter-quartile range). Scores will be plotted to explore the pattern over time and to examine differences between treatment arms. Differences in health-related quality of life between the treatment arms and the placebo arm will be conducted through linear mixed models and growth curve models to account for repeated assessments. Trial outcome index score is 0-92 with 0 being the worst and 92 being the best.
Change in Function Subscales	Baseline to 6 months	Health-related quality of life scores at each timepoint and changes in scores between 6 months and baseline will be summarized by mean standard deviation, median (inter-quartile range). Scores will be plotted to explore the pattern over time and to examine differences between treatment arms. Differences in health-related quality of life between the treatment arms and the placebo arm will be conducted through linear mixed models and growth curve models to account for repeated assessments. Function subscales score is 0-28 with 0 being the worst and 28 being the best.
Change in Lung Cancer Subscale of the Functional Assessment of Cancer Therapy-Lung	Baseline to 6 months	Health-related quality of life scores at each timepoint and changes in scores between 6 months and baseline will be summarized by mean standard deviation, median (inter-quartile range). Scores will be plotted to explore the pattern over time and to examine differences between treatment arms. Differences in health-related quality of life between the treatment arms and the placebo arm will be conducted through linear mixed models and growth curve models to account for repeated assessments. Lung cancer subscale score is 0-36 with 0 being the worst and 36 being the best.
Patient-reported Outcome Assessed by Patient-Reported Outcome-Common Terminology Criteria for Adverse Events	Up to 2 years	Patient-Reported Outcome-Common Terminology Criteria for Adverse Events items will be summarized by arm. Patient-Reported Outcome-Common Terminology Criteria for Adverse Events response will be compared between the treatment arms vs. placebo arm using a chi-square test or Fisher's exact test as appropriate.

Opioid-induced Constipation Rating Scale	Baseline to 6 months	Opioid-induced constipation rating scale will be summarized by arm. Scores will be compared between treatment arms vs. placebo arm using Wilcoxon test. Question from Bowel Function Diary is "In the past 24 hours, how much pain did you feel in your abdomen because of constipation?". Opioid-induced constipation rating scale is from 0-6, with 0 being none and 6 being very severe.
Level of Pain	Baseline to 6 months	Pain scores will be summarized by arm. Pain scores will be compared between treatment arms vs. placebo using Wilcoxon test. Pain score scale is 0-10, with 10 being worst pain imaginable
Analgesic Use	Up to 2 years	The protocol-defined analysis for this secondary endpoint was not performed due to not specifying analgesic use in the questionnaire. Analgesic use will be summarized by arm. Frequencies of analgesic used will be compared using chi-square test or Fisher's exact test, as appropriate.
Unexpected Clinical Outcomes With Chemotherapy	Up to 2 years	A Fisher's exact test was not performed due to low sample size. Frequency of discontinuation of chemotherapy will be summarized by arm and compared between each treatment arm vs the placebo arm using Fisher's exact test.
Progression-free Survival Assessed by Using the Standard Response Evaluation Criteria in Solid Tumors 1.1 Criteria	From randomization to disease progression/relapse, death, or loss to follow-up, whichever occurs first, assessed up to 2 years	Progression-free survival probabilities will be estimated by arm using the Kaplan-Meier estimator. In an exploratory manner, a Cox proportional hazards model will be used to determine the effect of naloxegol on progression-free survival.
Overall Survival	From randomization to death or loss to follow-up, whichever occurs first, assessed up to 2 years	Overall survival probabilities will be estimated by arm using the Kaplan-Meier estimator. In an exploratory manner, a Cox proportional hazards model will be used to determine the effect of naloxegol on overall survival.
