Actinium Announces Oral Presentation Detailing Improved Survival Outcomes in TP53 Positive Patients at the EHA 2024 Annual Congress and Presentation of Long-Term Efficacy Results in Older Patients Receiving an Iomab-B Led Bone Marrow Transplant in the Phase 3 SIERRA Trial
- Median Overall Survival of 5.49 months observed in patients with a TP53 mutation receiving an Iomab-B led allogeneic bone marrow transplant compared to 1.66 months in patients that did not receive Iomab-B (hazard ratio=0.23, p=0.0002) in the Phase 3 SIERRA Trial
- Long-term efficacy results in older patients with active relapsed or refractory acute myeloid leukemia also observed in the SIERRA trial
In total, 24% (37/153) of the patients enrolled on SIERRA had a TP53 mutation, which is usually associated with limited treatment options and poor outcomes. Median Overall Survival of 5.49 months observed in patients with a TP53 mutation receiving an Iomab-B led allogeneic bone marrow transplant compared to 1.66 months in patients that did not receive Iomab-B (hazard ratio=0.23, p=0.0002).
Iomab-B EHA presentations titles are as follows:

About
Actinium develops targeted radiotherapies to meaningfully improve survival for people who have failed existing oncology therapies. Advanced pipeline candidates Iomab-B (pre-BLA & MAA (EU)), an induction and conditioning agent prior to bone marrow transplant, and Actimab-A (National Cancer Institute CRADA pivotal development path), a therapeutic agent, have demonstrated potential to extend survival outcomes for people with relapsed and refractory acute myeloid leukemia. Actinium plans to advance Iomab-B for other blood cancers and next generation conditioning candidate Iomab-ACT to improve cell and gene therapy outcomes. Actinium holds more than 230 patents and patent applications including several patents related to the manufacture of the isotope Ac-225 in a cyclotron.
