Summary

A new bone-seeking radiopharmaceutical drug, called Radium-223 dichloride (formerly known as "Alpharadin"), is currently under development. It is an injectable aqueous solution containing radium-223, a radionuclide that emits radiation of another quality and with a different distribution than radiopharmaceuticals currently in use.

After injection of the drug into the blood, a large portion of the drug will accumulate in the bones, and irradiate the skeletal metastases. The drug is expected to be retained longer in the painful sites of bone than in other sites of the body, and may alleviate pain through its radiation. Radium-223 is expected to be both efficacious as regards the targeted localised irradiation, and also to have a favourable safety profile.

The radiopharmaceutical drug Radium-223 has not been given to humans before. In this first clinical study in man, a so-called phase I study, the safety, tolerance and the toxicity of various radioactivity doses of Radium-223 will be evaluated.

Conditions

  • Neoplasm Metastasis

Interventions

RADIATION

Radium-223 dichloride (BAY88-8223)

\- Single injection. Starting dose 46 kBq/kg b.w. Escalating doses 93, 163, 213 and 250 kBq/kg b.w. (9.8.2 Changes in addition to those described in amendments) After completion of the five dose levels above, the protocol was amended and the study extended to include patients to received multiple injections of Radium-223 - Re-treatment: Patients who had earlier been included in the study and received dose levels 46, 93 or 163 kBq/kg b.w. could be given a second injection, provided that the total dose did not exceed 250 kBq/kg b.w. - Fractionated dose (multiple dosing) Patients were given multiple injections in treatment: 5 injections of 50 kBq/kg b.w. at 3 weeks intervals. Patients were given multiple injections in treatment: 2 injections of 125 kBq/kg b.w. at 6 weeks interval
