Registered outcomes10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Overall response rate | Up to 5 years | Estimated along with exact 95% binomial confidence intervals in each arm and compared between arms using the z-test statistic. |
| Secondary | Progression free survival (PFS) | Time from the date of randomization to the date of first documented progression or death due to any cause, assessed up to 5 years | Progression will be measured by Response Evaluation Criteria in Solid Tumors 1.1 criteria. Log-rank test will be used to compare PFS between treatment and control. Median survival time and the corresponding confidence intervals will be calculated by the Kaplan-Meier Method. |
| Other | Plasma hPG80 | Up to 5 years | Analysis of variance will be used to analyze plasma hPG80 concentration. Baseline plasma hPG80 will be used as covariate. F-test and t-test will be conducted to test the differences in hPG80 change between treatment arms and responses. |
| Other | Plasma deoxyribonucleosides | Pre- to post-triapine administration | Will evaluate plasma deoxyribonucleosides as a biomarker of triapine resistance. Pre and post triapine administration changes in deoxyribonucleosides will be analyzed by pair-wise t-test, stratified by study arm. Secondary and exploratory analysis on repeatedly measured deoxyribonucleosides will entail a linear mixed model for comparison between treatment groups. |
| Other | Circulating deoxyribonucleic acid (ctDNA) | Up to 5 years | ctDNA will be analyzed by summary descriptive statistics as well as visualization graphics such as heat maps. Data processing and downstream data analysis pipelines for the genomic data will be performed including differential analysis for comparison of genomic data between arms using the limma package in R/Bioconductor with adjustment for false discovery rate. |
| Other | Triapine plasma pharmacokinetics (PK): Maximum concentration | Up to 5 years | Will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated. PK parameters will be reported descriptively for exploratory comparison with historical data. Smoking status will be a particular covariate to be evaluated as a determinant of PK. Exploratory correlative studies with pharmacodynamics (biological endpoints, toxicity and efficacy) will be analyzed using nonparametric statistics. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy. |
| Other | Triapine plasma PK: Area under the concentration-time curve | Up to 5 years | Will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated. PK parameters will be reported descriptively for exploratory comparison with historical data. Smoking status will be a particular covariate to be evaluated as a determinant of PK. Exploratory correlative studies with pharmacodynamics (biological endpoints, toxicity and efficacy) will be analyzed using nonparametric statistics. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy. |
| Other | Triapine plasma PK: Half-life | Up to 5 years | Will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated. PK parameters will be reported descriptively for exploratory comparison with historical data. Smoking status will be a particular covariate to be evaluated as a determinant of PK. Exploratory correlative studies with pharmacodynamics (biological endpoints, toxicity and efficacy) will be analyzed using nonparametric statistics. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy. |
| Other | Triapine plasma PK: Apparent clearance | Up to 5 years | Will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated. PK parameters will be reported descriptively for exploratory comparison with historical data. Smoking status will be a particular covariate to be evaluated as a determinant of PK. Exploratory correlative studies with pharmacodynamics (biological endpoints, toxicity and efficacy) will be analyzed using nonparametric statistics. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy. |
| Other | Triapine plasma PK: Apparent volume of distribution | Up to 5 years | Will be tabulated and descriptive statistics (e.g., geometric means and coefficients of variation) calculated. PK parameters will be reported descriptively for exploratory comparison with historical data. Smoking status will be a particular covariate to be evaluated as a determinant of PK. Exploratory correlative studies with pharmacodynamics (biological endpoints, toxicity and efficacy) will be analyzed using nonparametric statistics. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy. |
