Condition(s) targeted: Refractory Multiple Myeloma; Stage I Multiple Myeloma; Stage II Multiple Myeloma; Stage III Multiple Myeloma

Intervention: clarithromycin (Drug); thalidomide (Drug); dexamethasone (Drug)

Phase: Phase 2

Status: Active, not recruiting

This phase II trial studies the side effects and how well giving thalidomide, dexamethasone, and clarithromycin together works in treating patients with multiple myeloma previously treated with transplant. Biological therapies, such as thalidomide and clarithromycin, may stimulate the immune system in different ways and stop cancer cells from growing. Dexamethasone also works in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving thalidomide together with dexamethasone and clarithromycin after a transplant may be an effective treatment for multiple myeloma

Clinical Details

Official title: Maintenance Therapy With Thalidomide, Dexamethasone and Clarithromycin (Biaxin) Following Autologous/Syngeneic Transplant for Multiple Myeloma

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Toxicity of proposed treatment with clarithromycin, dexamethasone, and thalidomide

Secondary outcome: Time to disease progression

Detailed description: OBJECTIVES: I. Evaluate the toxicity of the use of Thalidomide/Biaxin (Clarithromycin)/Dexamethasone as maintenance therapy after autologous/syngeneic transplant. II. Evaluate the median time to disease progression. III. Evaluate survival. OUTLINE: Patients receive thalidomide orally (PO) once daily (QD), dexamethasone PO once weekly, and clarithromycin PO twice daily (BID). Treatment continues for 1 year in the absence of disease progression or unacceptable toxicity. Treatment with thalidomide continues in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up periodically.


Minimum age: 14 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- Any autologous or syngeneic patient who underwent high dose melphalan (>= 140 mg/m^2)

therapy/peripheral blood stem cell (PBSC) or bone marrow (BM) rescue for any stage of multiple myeloma and did not participate in another clinical transplant trial which is also evaluating disease free survival or survival

- Platelet count (transfusion independent) > 50,000 cells/mm^3 for 5 calendar days

after recovery from high dose

- Absolute granulocyte count > 1500 cells/mm^3 for 5 calendar days after recovery from

high dose

- Patients will start therapy between 30 days to 120 days after transplant

the care of the patients on study and comply with the FDA-mandated S. T.E. P.S. Program

- Patients unwilling to practice adequate forms of contraception if clinically

indicated; male patients on study need to be consulted to use latex condoms even if they have had a vasectomy every time they have sex with a woman who is able to have children while they are being treated and for four weeks after stopping drugs
