Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Cumulative Overall Response Rate (ORR) | Up to 6 cycles | Will be evaluated by Myelodysplastic Syndrome International Working Group (IWG) 2006 criteria (Cheson et al., 2006) and acute myeloid leukemia (AML) IWG 2003 criteria (Cheson et al., 2003) after 6 cycles of treatment. Cumulative ORR will include complete remission (CR), complete remission with incomplete blood count recovery (CRi), partial response (PR), and bone marrow complete remission (marrow CR) achieved at least at one point during these 6 cycles. |
| Secondary | ORR | Up to 12 months | The effectiveness of the drug in patients for each cohort will be independently assessed by ORR. The exact two-sided 95% confidence intervals (CI) for the ORR will be reported. The CI based on the Greenwoods variance will be reported. |
| Secondary | Progression-free Survival (PFS) | From first day of therapy to the time of documentation of progression, death of any cause, or last follow-up, whichever comes first, assessed up to 12 months | Will be estimated using the Kaplan-Meier method with the 95% CIs. The CI based on the Greenwoods variance will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease on the survival data. The adjusted p-values of the odds ratios and the adjusted 95% confidence interval will be reported. |
| Secondary | Overall Survival (OS) | From first day of therapy to the time of death or last follow-up, whichever comes first, assessed up to 12 months | Will be estimated using the Kaplan-Meier method with the 95% CIs. The CI based on the Greenwoods variance will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease on the survival data. The adjusted p-values of the odds ratios and the adjusted 95% confidence interval will be reported. |
| Secondary | Duration of Response (DOR) | From first documentation of response to the time of documentation of progression, death of any cause, or last follow-up, whichever comes first, assessed up to 12 months | |
| Secondary | Incidence of Adverse Events | Up to 12 months | Non-hematologic toxicity will be evaluated by Common Terminology Criteria for Adverse Events version 5 criteria. Presented are the count of those that experienced at least one non-serious adverse event. |
| Other | Change in 2-hydroxyglutarate (2HG) Levels | Up to 12 months | The Mann-Whitney U test will be used to test for differences in post-treatment plasma 2HG concentrations between patients with a response to treatment and those without. Will also test for differences in Delta2HG (defined as pre-treatment minus post-treatment plasma concentration) between patients with a response to treatment and those without. Differences with p =\< 0.05 will be considered significant. The area under the receiver operating characteristic curve (ROC AUC) will be calculated to determine the cutoff value of the Delta2HG difference. The optimal cutoff value will be determined at the point on the ROC curve at (sensitivity + specificity - 1) is maximized. |
| Other | Minimal Residual Disease (MRD) Assessment | Up to 12 months | Will define MRD based on the variation of the variant allele frequency of the IDH1/2 mutation in the bone marrow of the patients before and during therapy. Will evaluate two different variables: MRD negativity (defined by the absence of detection of the IDH mutant in the sample) and the molecular response (defined by the log reduction of the frequency of the mutant allele). MRD negativity is a qualitative variable and will be reported as a percentage with 95% confidence interval for each time point and mutation. Will compare the different groups using a Chi-Square test. Molecular response is a quantitative variable reported as a median, min and max for each time point and we will use a student t test for the comparison of the different groups. |
| Other | Mutant Allele Frequency | Up to 12 months | Will be estimated using Poisson distribution model as the fraction of positive reads divided by total reads containing a target. The limit of detection will be defined for each mutation as the mean value of IDH1/2 wild-type controls plus three standard deviations. |
