The Q2W regimen had a better hematological safety profile with no related discontinuations. Conclusions Safety and efficacy of ELU001 demonstrated expected, manageable safety profile based on the payload, exatecan, with promising activity in heavily pretreated patients across several cancer indications with low, moderate or high FRα expression.
The study is actively enrolling in the US and currently recruiting in Q2W Cohort 201 and Q3W Cohort A. QW Cohorts 1-3 and Q2W Cohort 101 are complete. Clinical trial information: NCT05001282.
Retreatment of these animals resulted in an additional decrease in tumor burden. These results suggest that ELU001 may have promise for the treatment of metastatic brain tumors that are difficult to treat with currently available agents.
When compared with an anti-FRα-DM4 ADC, EC112002 demonstrated deeper penetration into 3D cell-line-derived tumor spheroids and superior specific cytotoxicity in a panel of 3D patient-derived tumor spheroids, as well as enhanced efficacy in cell-line-derived and patient-derived in vivo tumor xenograft models expressing a range of low to high levels of FRα. With the growing interest in developing clinically translatable, safe, and efficacious DDSs, EC112002 has the potential to address some of the critical limitations of the current systemic drug delivery for cancer management.
No ELU001 anti-drug antibodies were induced in either species. In summary, ELU001 has a favorable nonclinical safety/TK profile and is currently under evaluation in a clinical safety study - NCT05001282.
