Brief Summary:
This is a first-in-human, single-arm, open-label, dose escalating study to determine the safety and the recommended maximum tolerated dose of the AMT in subjects with malignant cutaneous lesions.
AMT is a combination therapy of a drug (IUdR) and a device (AUTRON Therapy System). IUdR is an iodinated thymidine analogue that is preferentially incorporated into DNA in rapid growing cells. The AUTRON Therapy System generates characteristic X-Ray photons around 33.4 keV, matching the K-edge energy of Iodine (33.17 keV), which can efficiently induce Auger electron emissions from IUdR in cancer DNA, resulting in extensive DNA damage and cancer cell death.
Detailed Description:
NanoRay Biotech is developing a novel investigational therapeutic system called Auger Molecular Therapy (AMT), which consists of a drug, Iododeoxyuridine (IUdR), and a medical device, AUTRON Therapy System, intended for the palliative treatment of malignant cutaneous lesions. IUdR is an iodinated analogue of deoxyuridine, which can be incorporated into DNA of cancer cells because it is a thymidine analogue. The AUTRON Therapy System is a complete, standalone low energy X-Ray radiation source (80 kVp, 100 μA) intended for local irradiation. The AUTRON Therapy System contains a novel design of transmission type X-Ray tube, which allows electron beams to pass through the metal target and generates characteristic X-Ray similar to synchrotron radiation.
The combination product is intended to induce Auger effect to augment the damage on tumor cells, while lowering the adverse effect on normal cells. IUdR is an iodinated thymidine analogue that is preferentially incorporated into DNA in rapid growing cells (such as cancer cells) after administration. The AUTRON Therapy System generates characteristic X-Ray photons around 33.4 keV, matching the K-edge energy of Iodine (33.17 keV), which can efficiently induce emissions of Auger electrons when hitting the Iodine atoms on IUdR in cancer DNA, resulting in extensive DNA damage and cancer cell death. Furthermore, the characteristic X-Ray photons generated by the AUTRON Therapy System have a low penetration rate in biological materials, which give the maximum dose on superficial lesions and much reduced dose on peripheral or deep normal tissues, fitting the need on the management of malignant cutaneous lesions.
