IMO-8400 for Relapsed or Refractory Waldenstrom's Macroglobulinemia (UW14016)
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
Status Conditions Phase Study ID
Recruiting Waldenstrom's Macroglobulinemia Phase I/II UW14016

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.
