Huynh T, Feng Y, Meshaw R, Zhao X, Rosenfeld L, Vaidyanathan G, et al.
Nucl Med Biol . 2024 May; 134-135:108913. PMID: 38703588
Introduction: Single domain antibody fragments (sdAbs) are an appealing scaffold for radiopharmaceutical development due to their small size (~15 kDa), high solubility, high stability, and excellent tumor penetration. Previously, we...

Nucl Med Biol . 2024 May; 134-135:108916. PMID: 38703587
Introduction: Targeted α-particle therapy agents have shown promising responses in patients who have developed resistance to β-particle emitting radionuclides, albeit off-target toxicity remains a concern. Astatine-211 emits only one α-particle...

Feng Y, Sarrett S, Meshaw R, Vaidyanathan G, Cornejo M, Zeglis B, et al.
J Med Chem . 2022 Nov; 65(22):15358-15373. PMID: 36368007
Because of their rapid tumor accumulation and normal tissue clearance, single-domain antibody fragments (sdAbs) are an attractive vehicle for developing radiotherapeutics labeled with the α-emitter At. Herein, we have evaluated...

Neurooncol Adv . 2022 Sep; 4(1):vdac135. PMID: 36128586
Background: Single-domain antibody fragments (aka VH, ~ 13 kDa) are promising delivery systems for brain tumor theranostics; however, achieving efficient delivery of VH to intracranial lesions remains challenging due to...

Batra V, Samanta M, Makvandi M, Groff D, Martorano P, Elias J, et al.
Clin Cancer Res . 2022 Jul; 28(18):4146-4157. PMID: 35861867
Purpose: [131I]meta-iodobenzylguanidine ([131I]MIBG) is a targeted radiotherapeutic administered systemically to deliver beta particle radiation in neuroblastoma. However, relapses in the bone marrow are common. [211At]meta-astatobenzylguanidine ([211At] MABG) is an alpha...

Feng Y, Meshaw R, Zhao X, Jannetti S, Vaidyanathan G, Zalutsky M
J Nucl Med . 2022 May; 64(1):124-130. PMID: 35618478
Single-domain antibody fragments (sdAbs) are attractive for targeted α-particle therapy, particularly with At, because of their rapid accumulation in tumor and clearance from normal tissues. Here, we evaluate the therapeutic...

Sci Rep . 2022 Feb; 12(1):3020. PMID: 35194100
Radiopharmaceutical therapy (RPT) is an attractive strategy for treatment of disseminated cancers including those overexpressing the HER2 receptor including breast, ovarian and gastroesophageal carcinomas. Single-domain antibody fragments (sdAbs) exemplified by...

Nucl Med Biol . 2021 Jun; 100-101:24-35. PMID: 34146837
Introduction: Labeling single domain antibody fragments (sdAbs) with F is an attractive strategy for immunoPET. Earlier, we developed a residualizing label, N-succinimidyl 3-((4-(4-fluorobutyl)-1H-1,2,3-triazol-1-yl)methyl)-5-(guanidinomethyl)benzoate ([F]RL-I), synthesized via a click reaction for...

J Nucl Med . 2021 Jun; 63(2):259-267. PMID: 34088772
α-Particle emitters targeting the prostate-specific membrane antigen (PSMA) proved effective in treating patients with prostate cancer who were unresponsive to the corresponding β-particle therapy. At is an α-emitter that may...
