Trial Outcomes & Findings for MUC1 Vaccine in Preventing Lung Cancer in Current and Former Smokers at High Risk for Lung Cancer (NCT NCT03300817)

NCT ID: NCT03300817

Last Updated: 2025-06-12

Results Overview

Will be evaluated by monitoring changes in IgG anti-MUC1 antibody titer ratio; defined as t12/t0, where t0 is the "initial titer" measured prior to vaccination, and t12 is the "final titer" drawn at 12 weeks. A titer ratio of \>= 2 will be considered a positive response.

PRIMARY outcome

Timeframe: At week 12

Population: 4 patients are excluded from this analysis because they did not receive injections at weeks 2 and 10

Will be evaluated by monitoring changes in IgG anti-MUC1 antibody titer ratio; defined as t12/t0, where t0 is the "initial titer" measured prior to vaccination, and t12 is the "final titer" drawn at 12 weeks. A titer ratio of \>= 2 will be considered a positive response.

Interval 5.1 to 26.8

PRIMARY outcome

Timeframe: 24 weeks

Will be assessed according to National Cancer Institute Common Toxicity Criteria version 4.0. The maximum grade for each type of adverse event will be recorded for each participant and frequency tables will be reviewed to determine the overall patterns. In addition, the number and severity of adverse events will be tabulated and summarized across all grades.

SECONDARY outcome

Timeframe: 12 weeks

To explore potential differences, if any, in the immunogenicity of the vaccine (as assessed at week 12 by the IgG anti-MUC1 antibody titer ratio) in current vs. former smokers.

SECONDARY outcome

Timeframe: 12 weeks

Population: Only patients with available data on levels of circulating myeloid derived suppressor cells at 12 weeks are included

Will correlate with the ability to respond to the vaccine. Will summarize the data using descriptive statistics and graphical methods (i.e. boxplots, scatter plots, etc.). For continuous MDSC data versus response data, will use t-tests or Wilcoxon Rank-Sum tests (for non-normal data).

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to week 12

Will explore the relationship between COPD status at pre-registration and immune response in current versus former smokers. In individuals with COPD, the severity of airflow obstruction will be measured by the pulmonary function tests as per the GOLD classification.
