摘要
The present prospective phase 1/2 study aimed to elucidate the efficacy and safety of 177 Lu-DOTATATE (four cycles of 7.4 GBq) in Japanese patients with unresectable, progressive neuroendocrine tumors (NETs).From April 2018 to October 2020, 15 patients with advanced NETs (five midgut, eight pancreatic, and two lung NETs) were enrolled. Objective response rate (ORR), progression-free survival (PFS), and adverse events (AEs) were evaluated. Pharmacokinetics and dosimetry were also evaluated in three midgut patients.The mean absorbed doses of 177 Lu-DOTATATE to the kidneys (20.7 Gy/29.6 GBq) and the bone marrow (0.631 Gy/29.6 GBq) were within the radiation tolerance doses. The ORR of the whole population was 53% (90% CI, 30%-76%). ORRs of the midgut and non-midgut NETs were 60% (90% CI, 19%-92%) and 50% (90% CI, 22%-78%), respectively. There was no difference in the maximum reduction rate of the sum of the target lesion diameters between patients with midgut and non-midgut NET. The median PFS was not reached; the PFS rate at 52 weeks was 80% (90% CI, 56.1%-91.7%). AEs of Grade 3 or higher were lymphopenia (47%) and leukopenia (7%).177 Lu-DOTATATE demonstrated remarkable tumor shrinkage and tolerability in Japanese patients with advanced NETs.
