Dual purpose enabling a targeted medicine approach
Part of a treatment strategy known as theragnostics, radiopharmaceuticals can be used for both therapy and diagnosis.
Radiopharmaceuticals, when tethering a radionuclide suitable for imaging, create a map of cancerous tumors in the body that provides precise diagnostic information. From the imaging results, the patients who are most likely to respond are identified and treated with individualized regiments of the therapeutic version of the same radiopharmaceutical. This precision medicine approach seeks to make substantial improvements in clinical outcomes.
Approach
Small molecules, tethered with powerful radioisotopes, are designed to exquisitely bind to receptors overexpressed in cancer and deliver powerful radiation to kill tumors, without affecting normal tissue.
Our unique approach marries a vast knowledge of GPCR biology with unrivaled proficiency in small molecule medicinal chemistry to develop potent and highly selective radiopharmaceuticals. We take a fit-for-purpose approach, pinpointing the precise target and selecting the ideal small molecule ligand paired with the optimal radioisotope to achieve a therapeutic effect.
Novel targets for solid tumors
Largest gene family in humans
132 known protein/receptor pairs
>65 with increased tumor expression
Given GPCR overexpression in many tumors, they can be targeted in a vast range of cancer indications, from common to rare tumors.
Clinical trials
Study R8760-101 is a multi-center Phase 1 clinical trial evaluating the safety and dosimetry of 68Ga-R8760, a first-in-class small molecule radioligand imaging agent being developed for patients diagnosed with adrenocortical carcinoma. 68Ga-R8760 was discovered by Radionetics Oncology for identifying melanocortin 2 receptor (MC2R)-expressing adrenocortical cancer lesions to select patients who may benefit from MC2R-directed radioconjugate therapy.
