Safety and Anti-Disease Activity of Oral Tosedostat (CHR-2797) in Elderly Subjects With Refractory or Relapsed AML (OPAL)
The purpose of this study is to evaluate the efficacy and safety of tosedostat in elderly patients suffering from refractory or relapsed AML.
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||The OPAL Study: A Phase II Study to Evaluate the Efficacy, Safety and Tolerability of Tosedostat (CHR-2797) in Elderly Subjects With Treatment Refractory or Relapsed Acute Myeloid Leukemia|
- The primary objective of the study is to evaluate the efficacy of tosedostat in elderly subjects with treatment refractory or relapsed AML by measuring CR and CRp. [ Time Frame: Months 1, 2, 3 & 6 ] [ Designated as safety issue: No ]
- To evaluate the safety and tolerability of tosedostat in elderly subjects with treatment refractory or relapsed AML [ Time Frame: Screening, Days 1, 2, 8, 15, 29, monthly thereafter + unschedulded visits when deemed necessary ] [ Designated as safety issue: Yes ]
- To evaluate the efficacy of tosedostat in elderly subjects with treatment refractory or relapsed AML, as determined by measures other than CR and CRp for the type and duration of response [ Time Frame: Months 1, 2, 3 & 6 ] [ Designated as safety issue: No ]

oral, once daily administration of tosedostat to evaluate its efficacy, safety and tolerability
In Part A, approximately 70 subjects will be randomized to one of 2 dose regimens of tosedostat which will be administered orally, once daily. The dose regimens of tosedostat will be:
In Part B a further 130 subjects will receive the dose regimen of tosedostat identified in Part A as being appropriate, based on the interim analysis during Part A.
There is an urgent need for novel compounds and treatment strategies for elderly patients with AML, particularly those with refractory or relapsed disease for whom there are few effective treatment options. Treatment options for elderly patients are further limited by co-morbidity and tolerability constraints.
Tosedostat is a new aminopeptidase inhibitor, which in preclinical experiments has shown potent activity in both in vitro and in vivo cancer models as a single agent. In early clinical studies particularly good results have been observed in refractory and relapsed AML in older patients and these observations form the basis for the current study.
This multi-center, open label phase II study will enrol approximately 70 subjects in Part A and 130 subjects in Part B.
