Safety, pharmacokinetics, and dosimetry of 177Lu-AB-3PRGD2 in patients with advanced integrin αvβ3-positive tumors: A first-in-human study

Integrin αvβ3 is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of 177Lu-AB-3PRGD2, a novel integrin αvβ3-targeting radionuclide drug with...

description Integrin αvβ3 is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of 177Lu-AB-3PRGD2, a novel integrin αvβ3-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin αvβ3-avid tumors were recruited to accept 177Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6–8 weeks. No adverse event over grade 3 was observed. 177Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of 177Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin αvβ3-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.
