Phase 1/2 Dose Escalation Study in Patients With Relapsed or Refractory Waldenstrom's Macroglobulinemia
Trial ID or NCT#
Recent reports have identified a specific oncogenic mutation L265P of the MYD88 gene in approximately 90% of the patients with Waldenström's macroglobulinemia. MYD88 is a key linker protein in the signaling pathway of Toll Like Receptors (TLRs) 7, 8, and 9, and IMO-8400 is an oligonucleotide specifically designed to inhibit TLRs 7,8, and 9. The scientific hypothesis for use of IMO-8400 to treat patients with Waldenström's macroglobulinemia depends on the inhibition of mutant MYD88 signaling in the TLR pathway, thereby interrupting the proliferation of cell populations responsible for the propagation of the disease.
Phase 1/2 Open-Label, Multiple-dose, Dose-escalation Study to Evaluate the Safety and Tolerability of IMO-8400 in Patients With Relapsed or Refractory Waldenstrom's Macroglobulinemia
