Actinium Announces Iomab-B Markedly Increases Long Term Survival in Patients 65 Years or Older with Active Relapsed or Refractory AML in the Phase 3 SIERRA Trial at the 2024 Tandem Meetings | Transplantation & Cellular Therapy Meetings of ASTCT® and CIBMT
NEW YORK, Feb. 26, 2024 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a leader in the development of targeted radiotherapies, reported new analyses from the positive Phase 3 SIERRA trial of Iomab-B in oral presentations at the at the 2024 Tandem Meetings | Transplantation & Cellular Therapy (TCT) Meetings of ASTCT® (American Society for Transplantation and Cellular Therapy and CIBMTR® (Center for International Blood and Marrow Transplant Research). The presentations reported unprecedented 100% access to potentially curative bone marrow transplant (BMT) and engraftment in evaluable patients with active relapsed or refractory acute myeloid leukemia (r/r AML) and improved long-term survival outcomes greater than 2 years in patients age 65 or older. Patients with r/r AML age 65 and older who also have multiple comorbidities and high-risk cytogenetics have a poor prognosis are seldom offered BMT in current practice due to poor tolerance to induction and conditioning regimens and dismal outcomes. The SIERRA results presented at TCT demonstrate Iomab-B's ability to overcome multiple high-risk features including a TP53 genetic mutation, advanced age and treatment resistant disease. The two oral presentations at this year's TCT mark a total of ten oral presentations of the SIERRA results at various leading transplant, hematology and nuclear medicine conferences in the USA and Europe.
- The SIERRA results presented at TCT demonstrate Iomab-B's ability to overcome multiple high-risk features including a TP53 genetic mutation, advanced age and treatment resistant disease.
- Patients receiving Iomab-B had significantly higher rates of complete remission as well as durable complete remission compared to the control arm.
- Most importantly, Iomab-B produced improved long-term survival outcomes as only the patients receiving Iomab-B achieved 1-year and 2-year survival.
- Iomab-B represents an important advancement in transplant conditioning and has the potential to address a significant unmet patient need."
