Combining targeted radioactive medicines with external beam radiation

Combination Radiopharmaceutical Therapy and External Beam Radiotherapy

NIH-funded research Johns Hopkins University · NIH-11167469

This approach gives a targeted radioactive drug together with external beam radiation to treat people with advanced or metastatic differentiated thyroid cancer who are unlikely to respond to radioiodine alone.

What this research studies

You would receive an injected radiopharmaceutical that seeks out thyroid cancer cells along with focused external beam radiation directed at tumor sites. Imaging and specialized dosimetry software will be used to plan and personalize the radiation doses to protect normal organs. This is an early-phase (phase I) effort focused on determining safe dose combinations and monitoring side effects. Johns Hopkins will deliver the treatments while a company provides the planning tools to combine the two radiation-based therapies.

Who could benefit from this research

Good fit: Ideal candidates are people with differentiated (thyroid) cancer that has spread or recurred and who are not expected to be effectively treated with radioiodine alone.

Not a fit: People with cancers other than thyroid cancer, tumors that do not take up the radiopharmaceutical, or those with medical conditions making radiation unsafe are unlikely to benefit.

Why it matters

Potential benefit: If successful, this could improve control of widespread thyroid cancer while limiting harm to healthy tissues by tailoring radiation doses.

How similar studies have performed: Radiopharmaceutical therapy like radioiodine has a proven track record in thyroid cancer, but combining it with external beam radiation is a newer, early-stage approach under clinical testing.
