adecatumumab (MT201)

The fully human monoclonal antibody targeting EpCAM, adecatumumab, was conjugated with the photosensitizer IR700 at different dye-antibody ratios (DAR2, DAR4, DAR7) and tested on OE19 cells and xenograft mouse models under near-infrared light irradiation...Notable EpCAM expression and homogeneity underpin EpCAM as a promising target for NIR-PIT in EGJ adenocarcinoma. The fully human anti-EpCAM antibody may be suitable for NIR-PIT in EGJ adenocarcinoma.

All subjects received Sandostatin® (100μg immediate release; SIR) by deep SC injection 24h before MTD201... MTD201 (30mg) by either IM or SC injection produced continuous octreotide release over a period of at least 63 days at levels predicted to maintain efficacious plasma concentrations at steady state with a dosing interval of up to 8 weeks. Reduced plasma IGF-1 concentrations were maintained throughout the study period. Unlike marketed octreotide depot products, MTD201 can be simply and rapidly reconstituted in WFI to give a stable suspension injectable via 21G needle in a 1.5mL volume.
