Brief Summary:
This study will test the safety, tolerance, and efficacy of different doses of oral gallium maltolate. Patients will receive oral gallium maltolate twice daily for 28-consecutive days followed by 14 days off treatment. This dosing cycle will be repeated. Adverse effects will be assessed and the levels of gallium in serum will be measured. Any effect of the drug on the cancer and any improvement in cancer-related symptoms will also be measured.

Detailed Description:
Gallium maltolate is an orally bioavailable form of gallium. This is a safety, pharmacokinetic and preliminary efficacy study. The primary objective of the study is to assess the safety profile in patients after oral administration of different doses of gallium maltolate for up to six 42-day cycles (28 days of gallium maltolate, followed by 14 days off treatment). In addition, serum concentrations of gallium and associated pharmacokinetic variables will be measured. From this information, an optimal dose will be selected for assessment of anti-tumor efficacy. The study assesses the effects of oral administration of gallium maltolate on pain resulting from bony metastasis, on biochemical measures of bone turnover, and on disease progression and overall survival in patients with various refractory malignancies. Patients may receive up to 6 cycles of the investigational agent.
