Can a radioactive injection target bone tumors? a Dose-Finding trial aims to find out

NCT ID NCT06008483

First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time

Summary

This early-stage trial is testing an experimental drug called CycloSam (153-Sm-DOTMP), a radioactive compound that delivers radiation directly to bone tumors when injected. The study aims to find the safest dose in people aged 15 to 75 with solid tumors that have spread to the bone, including certain cancers like prostate, breast, lung, and sarcomas. Participants receive two doses, and researchers monitor for side effects and tumor response.

What this could mean

Active substance
a radiopharmaceutical called CycloSam (153-Sm-DOTMP) that delivers radiation directly to bone tumors when injected
What this could lead to
If successful, this could lead to a new treatment option for people with solid tumors that have spread to the bone, potentially slowing tumor growth.
What could go wrong
This is a very early Phase 1 trial with only 5 participants, focused on finding a safe dose. It is not designed to prove effectiveness, and there is a risk of serious side effects from radiation.
