Study of Iomab-B Prior to Hematopoietic Cell Transplant vs. Conventional Care in Older Subjects With Active, Relapsed or Refractory Acute Myeloid Leukemia

Official Title

A Multicentre, Pivotal Phase 3 Study of Iomab-B Prior to Allogeneic Hematopoietic Cell Transplant Versus Conventional Care in Older Subjects With Active, Relapsed or Refractory Acute Myeloid Leukemia (AML)

Summary:

The primary objective of this study is to demonstrate the efficacy of Iomab-B, in conjunction with a Reduced Intensity Conditioning (RIC) regimen and protocol-specified allogeneic hematopoietic stem cell transplant (HCT), versus Conventional Care in patients with Active, Relapsed or Refractory Acute Myeloid Leukemia (AML).

Trial Description

Primary Outcome:

• Durable Complete Remission (dCR) defined as CR or CRp lasting 180 days or more from time of initial CR or CRp is documented with evidence of subsequent relapse

Secondary Outcome:

• Overall Survival (OS) at 1 year from randomization

SIERRA is a pivotal Phase 3 randomized controlled study of Iomab-B in Relapsed or Refractory AML patients. The SIERRA trial has a primary endpoint of durable Complete Remission (dCR) at six months and a secondary endpoint of overall survival at one year. Iomab-B is intended to prepare and condition patients for a bone marrow transplant, also referred to as a hematopoietic stem cell transplant, in a potentially safer and more efficacious manner than intensive chemotherapy conditioning that is the current standard of care in bone marrow transplant conditioning.
