The α-emitter astatine-211 targeted to CD38 can eradicate multiple myeloma in a disseminated disease model

CD38-Targeted Immunochemotherapy in Refractory Multiple Myeloma: A New Horizon.

CD38 is a type II transmembrane glycoprotein that is highly expressed in multiple myeloma and is a promising target for immunotherapy. Daratumumab is a human monoclonal antibody that has potent anti-multiple myeloma activity both as monotherapy and in combination with other multiple myeloma treatments, and has breakthrough designation on this basis.

Can multiple myeloma become a curable disease?

Small Molecule MYC Inhibitor Conjugated to Integrin-Targeted Nanoparticles Extends Survival in a Mouse Model of Disseminated Multiple Myeloma.

UNLABELLED Multiple myeloma pathogenesis is driven by the MYC oncoprotein, its dimerization with MAX, and the binding of this heterodimer to E-Boxes in the vicinity of target genes. The systemic utility of potent small molecule inhibitors of MYC-MAX dimerization was limited by poor bioavailability, rapid metabolism, and inadequate target site penetration. We hypothesized that new lipid-based MY...

α-Radioimmunotherapy with 213Bi-anti-CD38 immunoconjugates is effective in a mouse model of human multiple myeloma

In spite of development of molecular therapeutics, multiple myeloma (MM) is fatal in most cases. CD38 is a promising target for selective treatment of MM. We tested radioimmunoconjugates consisting of the α-emitter ²¹³Bi coupled to an anti-CD38 MAb in preclinical treatment of MM. Efficacy of ²¹³Bi-anti-CD38-MAb was assayed towards different MM cell lines with regard to induction of DNA double-s...

Durable donor engraftment after radioimmunotherapy using α-emitter astatine-211-labeled anti-CD45 antibody for conditioning in allogeneic hematopoietic cell transplantation.

To reduce toxicity associated with external γ-beam radiation, we investigated radioimmunotherapy with an anti-CD45 mAb labeled with the α-emitter, astatine-211 ((211)At), as a conditioning regimen in dog leukocyte antigen-identical hematopoietic cell transplantation (HCT). Dose-finding studies in 6 dogs treated with 100 to 618 μCi/kg (211)At-labeled anti-CD45 mAb (0.5 mg/kg) without HCT rescue ...
