A Trial of TTI-622 in Patients With Advanced Relapsed or Refractory Lymphoma or Myeloma (TTI-622-01)
Multicenter, open-label, phase 1a/1b Dose Escalation and Expansion Trial of TTI-622 in Patients with Advanced Relapsed or Refractory Lymphoma or Myeloma.
This is a trial of TTI-622 in subjects with relapsed or refractory lymphoma or myeloma.
TTI-622 (SIRPα-IgG4 Fc), is a soluble recombinant fusion protein created by directly linking the sequences encoding the N-terminal CD47 binding domain of human SIRPα with the Fc domain of human immunoglobulin (IgG4). TTI-622 acts by binding human CD47 and preventing it from delivering an inhibitory "do not eat" (anti phagocytic) signal to macrophages.
This trial will be conducted in 2 phases: Phase 1a (Dose-escalation phase) and Phase 1b (Expansion Combination Treatment).
In the Dose-escalation Phase (phase 1a), subjects with lymphoma will be enrolled in sequential dose cohorts to receive TTI-622 to characterize safety, tolerability, pharmacokinetics, and the maximum-tolerated dose (MTD).
In the Combination Treatment Phase (phase 1b), TTI-622 will be given to subjects with CD20-positive lymphoma, classic Hodgkin lymphoma and Myeloma, in combination with other anti-cancer drugs, to further define safety and to characterize efficacy.
