Phase 1/2 Dose Escalation Study in Patients With Relapsed or Refractory Waldenstrom's Macroglobulinemia (8400-401)

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.

Primary Outcome Measures:
  • Safety and tolerability of IMO-8400 in patients with Waldenstrom's Macroglobulinemia [ Time Frame: 29 weeks (24 week treatment + 5 week follow up) ] [ Designated as safety issue: Yes ]
    Assessment of adverse events, injection site reactions and concomitant medications in escalating dose levels of IMO-8400.

Secondary Outcome Measures:
  • Assess the treatment effect [ Time Frame: 29 weeks (24 week treatment + 5 week follow up) ] [ Designated as safety issue: No ]
    To assess the treatment effect (clinical activity) of escalating dose levels of IMO-8400 using disease-specific international guidelines for classifying clinical response.

  • Identify an appropriate dose of IMO-8400 [ Time Frame: 29 weeks (24 weeks treatment + 5 week follow-up) ] [ Designated as safety issue: No ]
    To identify an appropriate dose of IMO-8400 for further clinical evaluation.

  • Characterize PK [ Time Frame: 29 weeks (24 weeks treatment + 5 week follow-up) ] [ Designated as safety issue: No ]
    To characterize the pharmacokinetics of escalating dose levels of IMO-8400 administered once weekly by SC injection.

Estimated Enrollment: 24
