Curcumin (Diferuloylmethane Derivative) With or Without Bioperine in Patients With Multiple Myeloma

Curcumin, a yellow substance extracted from the plant Curcuma longa, is commonly used as a food additive. It is a natural anti-inflammatory compound and has shown anti-tumor activity in the laboratory. Bioperine is a pepper extract that increases the absorption of nutrient supplements.

In this study, 6 patients at a time will be randomly assigned (as in the toss of a coin) to one of two groups of 3 patients each. One group (Arm A) will receive curcumin alone. The other group (Arm B) will receive curcumin in combination with Bioperine. There is an equal chance of being in either group. While on study you may receive standard supportive care as appropriate.

Both of the study agents will be taken by mouth two times a day. Each group will have five dose levels of curcumin, starting with the lowest dose. After 6 patients have been enrolled in the first level (3 in each arm), the next group will be treated at a new dose level. You will always receive the same dose during your treatment, which will continue for at least 12 weeks unless there is evidence that the disease has gotten worse or intolerable side effects occur. You may receive treatment up to one year depending on your response to treatment.

You may be treated as outpatient and may receive your treatment at home. You will be asked to return to M. D. Anderson every 4 weeks for evaluation and physical exam.

This is an investigational study. A total of up to 30 evaluable patients will take part in the study. All will be enrolled at M. D. Anderson.
