Y-mAbs Announces FDA Clearance of IND for its Lutetium-177 Labeled Omburtamab Antibody
177Lu-omburtamab-DTPA embodies the Company’s naked omburtamab antibody radiolabeled with lutetium-177, using DTPA to chelate the lutetium radioisotope to the antibody. Lutetium-177 is a beta-emitter with a half-life of 6.7 days and a maximum energy of 0.5 MeV, corresponding to a maximum soft-tissue penetration of approximately 1 mm.
We anticipate that an international multicenter Phase 1/2 clinical trial will be initiated for the screening of pediatric patients with medulloblastoma during the fourth quarter of 2020.
“Based on our clinical experience with 131I-omburtamab for B7-H3 positive brain metastasis, we are excited to see 177Lu-omburtamab-DTPA make its way to the clinic to establish the safety profile and to determine the maximum tolerated dose. In this study, we hope to leverage our clinical experience from treating 27 medulloblastoma patients with 131I-omburtamab, again using indwelling catheters for intracerebroventricular drug delivery,” said
