Exelixis Announces Promising Initial Dose-Escalation Results from the First-in-Human Phase 1 JEWEL-101 Tr
XB002, a next-generation tissue factor-targeting antibody-drug conjugate, was well-tolerated at multiple dose levels
Pharmacokinetic analysis confirmed XB002 was stable with low levels of free payload
Exelixis, Inc. EXEL today announced promising initial results from the ongoing dose-escalation stage of JEWEL-101, a phase 1 study evaluating XB002, Exelixis' next-generation tissue factor-targeting antibody-drug conjugate. The data are being presented on Friday, October 28 during the Antibody-drug Conjugates Poster Session (abstract 256) at 10:00 a.m. CEST at the 34th Symposium on Molecular Targets and Cancer Therapeutics hosted by the European Organisation for Research and Treatment of Cancer (EORTC), the National Cancer Institute (NCI) and the American Association for Cancer Research (AACR).
Following promising preclinical data, it is encouraging to see that XB002 was well-tolerated across multiple dose levels with a pharmacokinetic analysis supporting the ability of XB002 to remain stable after infusion and reach its target before releasing its cytotoxic payload, said Susanna Ulahannan, M.D., M.Med., Assistant Professor of Medicine in the Section of Hematology/Oncology, University of Oklahoma College of Medicine and Associate Director of Oklahoma TSET Phase 1 Program, OU Health Stephenson Cancer Center at the OU Health Sciences Center. As the dose-escalation phase progresses, and we initiate enrollment into tumor specific cohorts, I look forward to learning more about how XB002 may benefit people with advanced solid tumors, in particular in tumor types with high unmet need.
