About Lumoxiti (moxetumomab pasudotox):
Lumoxiti is a CD22-directed cytotoxin and a first-in-class treatment in the US for adult patients with relapsed or refractory (r/r) hairy cell leukemia (HCL) who have received at least two prior systemic therapies, including treatment with a purine nucleoside analog. Lumoxiti is not recommended in patients with severe renal impairment (CrCl ≤ 29 mL/min).  It comprises the CD22 binding portion of an antibody fused to a truncated pseudomonas exotoxin.  The toxin inhibits protein synthesis and ultimately triggers apoptotic cell death. Lumoxiti received U.S. FDA approval in September 2018 and has been granted Orphan Drug Designation by the FDA for the treatment of r/r HCL. AstraZeneca is the current Biologics License Application (BLA) holder for Lumoxiti.

About the ‘1053’ Phase III trial:
The AstraZeneca-sponsored ‘1053’ trial is a single-arm, multicenter Phase III clinical trial assessing the efficacy and safety of Lumoxiti monotherapy in patients with r/r HCL who have received at least two prior therapies, including one purine nucleoside analog. The trial enrolled 80 patients and was conducted across 34 sites in 14 countries. The primary endpoint was durable complete response (CR), defined as CR with hematologic remission (blood count normalization) for >180 days. Secondary outcome measures included objective response rate, duration of complete and objective response, progression-free survival, safety/tolerability, pharmacokinetics and immunogenic potential.
