Clinical Trial Summary

This is a study of ADI-PEG 20 (pegylated arginine deiminase), an arginine degrading enzyme versus placebo in patients with malignant pleural mesothelioma. Malignant pleural mesothelioma have been found to require arginine, an amino acid. Thus the hypothesis is that by restricting arginine with ADI-PEG 20, the malignant pleural mesothelioma cells will starve and die.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Response Rate	Objective Response Rate is calculated as the proportion of subjects whose best tumor response from all post-baseline tumor assessments is complete response (CR) or partial response (PR). The best tumor response is the best response recorded from the start of the treatment until the end of treatment taking into account any requirement for confirmation.; To test Objective Response Rate significance, a Relative Risk Ratio (ADI-PEG 20 / Placebo) was calculated as the common relative risk of having a response (CR or PR) based on the Mantel-Haenszel estimator controlling for tumor histology (biphasic versus sarcomatoid).	approximately 18 months
Primary	Overall Survival Phase 3 Interim Analysis	The primary analysis of OS Phase 3 was performed at the interim analysis. This was performed once 50% of the planned OS events for phase 3 have occurred (ie, 169 of the 338 planned OS events). This interim analysis will evaluate OS in the ITT population in an unblinded manner. The OS data at the second interim analysis will be analyzed to support the following decisions: Futility stopping: Terminate the study due to futility at the interim analysis. Sample size re-estimation: Increase the target number of OS events after the second interim analysis.. The treatment effect on OS will be evaluated using the stratified log-rank test (stratified by tumor histology).	Approximately 18 months
Primary	Overall Survival	Overall survival is defined as the time from randomization until death. In the event that no death was documented prior to study termination or analysis cutoff, OS was censored at the last known date the subject was known to be alive, either through completion of on-study visits or through survival follow-up contact.; The treatment effect on OS was evaluated using the stratified log-rank test (stratified by tumor histology).; The Kaplan-Meier curves were also plotted. A Cox proportional hazard model with an adjustment for tumor histology (biphasic vs sarcomatoid) was used to compute the estimated hazard ratio and two-sided 95% CI. The treatment effect on OS was evaluated using the stratified log-rank test (stratified by tumor histology). The significance level to be used in the OS analysis at the final analysis was based on a = 0.04999 (two-sided).	18 months
Secondary	Progression Free Survival	The key secondary endpoint for the phase 3 portion is PFS, which will be analyzed only if the analysis of OS is statistically significant at the final analysis, with alpha level of 0.05 (two-sided) using the same statistical methodologies as applied to OS.	approximately 18 months
