Uptake and treatment effect of [177Lu]Lu-DPI-4452 in subcutaneous HT-29 and SK-RC-52 human xenograft mouse models. (A and B) Growth of HT-29 (A) and SK-RC-52 (B) xenografts treated with single doses of vehicle, 100 or 33 MBq of [177Lu]Lu-DPI-4452, or 3 once-weekly (QW × 3) 33 MBq doses of [177Lu]Lu-DPI-4452. Arrowheads indicate days of treatment (n = 10 per group). (C and D) Tumor uptake (percentage injected dose per gram of tissue, %ID/g) for HT-29 (C) and SK-RC-52 (D) xenografts at 4 h after injection (n = 3 per group). Shown are mean (bar) and individual values.
