CD33+ HL-60 leukemia xenograft in mice: >80% tumor growth inhibition
“In vivo antitumor effects of CMA-676 were studied in an HL-60 xenograft tumor model. CMA-676 showed a dose-response effect with >80% inhibition of tumor growth at doses between 0.8 and 2.4 mg/m2 NAc-gamma calicheamicin DMH equivalents”

Why that model
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
Xenograft doses far exceeded clinical doses, partly because subcutaneous HL-60 grows as a solid tumor
“were much higher than the doses used in clinical trials (0.25 to 9 mg protein/m2 ) at least in part because the subcutaneously implanted HL-60 leukemia grows as a solid tumor.”
