Trial Outcomes & Findings for Idasanutlin, Ixazomib Citrate, and Dexamethasone in Treating Patients With Relapsed Multiple Myeloma (NCT NCT02633059)

NCT ID: NCT02633059

Last Updated: 2024-09-19

Results Overview

Defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients (at least 2 of a maximum of 6 new patients). DLT is graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

PRIMARY outcome

Timeframe: Up to 6 months

Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true success proportion will be calculated.

Timeframe: 30 days after the last dose of study treatment, up to 3 years

Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses.

Timeframe: Up to 6 months

Population: Participants who had adverse events fitting the criteria

The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration.

SECONDARY outcome

Timeframe: Up to 6 months

The rate of PR will be estimated by the number of patients with a VGPR or PR divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true success proportions will be calculated.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline up to 6 months

Effect of inhibition of mdm2 will be assessed by measuring MIC levels. MIC levels at each time point and changes after treatment will be both graphically and quantitatively summarized and explored. Changes from baseline will be evaluated using Wilcoxon's signed rank test.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Up to 6 months

Impact of MDM2 inhibition on activation of p53 and clonal selection examined using gene expression profiling and exome sequencing

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Up to 6 months

Potential biomarkers associated with response will be assessed in an exploratory manner. Potential markers will be determined using gene expression profiling. The correlation between potential biomarkers and response (responders vs. non-responders) will be evaluated using Fisher's exact and Wilcoxon rank sum tests, where appropriate.
