New imaging agent aims to light up Hard-to-Find cancers
NCT ID NCT07052760
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial was designed to test whether a new radioactive imaging agent, 111In-ABD147, could help detect metastatic solid tumors using SPECT/CT scans. It targeted cancers like castration-resistant prostate cancer and high-grade neuroendocrine tumors. However, the study was withdrawn before any participants were enrolled, so no results are available.

Inclusion Criteria: 1. Age ≥ 18 years 2. Histopathologically confirmed solid tumors in one of the following cohorts: 1. Cohort 1 (n=15): Histologically confirmed prostate cancer, with castration resistant disease per Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria. 2. Cohort 2 (n=15): Histologically confirmed high grade neuroendocrine tumor, with a Ki-67 over 20. 3. Cohort 3 (n=15): Agnostic to tumor type. 3. Metastatic disease present on conventional imaging defined as having Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 measurable disease or multiple bone metastases. 4. Ability to understand a written informed consent document, and the willingness to sign it. Exclusion Criteria: 1. Unlikely to comply with protocol procedures, restrictions and requirements and judged by the Investigator to be unsuitable for participation. 2. Has known hypersensitivity to Chinese hamster ovary cell products. 3. Has a history of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins. 4. Known pregnancy.
