|Official Title:||UARK 98-036, A Phase II Trial of Combination Bisphosphonate and Anti-Angiogenesis Therapy With Pamidronate and Thalidomide in Patients With Smoldering/Indolent Myeloma|
- Best Response [ Time Frame: 2 years ]
Best response to study treatment as defined by protocol-specific response criteria:
Complete Response (CR) = absence of urine and serum M-components by immunofixation; bone marrow should be adequately cellular (>20%) with <1% monoclonal plasma cells by DNA-clg flow cytometry; serum calcium level must be normal; no new bone lesions nor enlargement of existing lesions; Normalization of serum concentrations of normal immunoglobulins is not required for CR. Partial Response (PR) = Reduction by > 75% in serum myeloma protein production; Decrease in monoclonal marrow plasmacytosis to <5%; Decrease in Bence-Jones proteinuria by >90%; No new lytic bone lesions or soft tissue plasmacytoma.
Treatment Failures/Progressive Disease (PD) = Such patients do not fulfill the above criteria and/or have new lytic lesions (but not compression fractures), hypercalcemia, or other new manifestations of disease.

Experimental: Thalidomide + Bisphosphonate
200 mg/day Thalidomide + 90 mg Pamidronate OR 4 mg Zometa every 2 weeks for 2 months and then every 4 weeks as maintenance therapy
Patients will receive either pamidronate or zometa. Pamidronate is administered at a dose of 90 mg by continuous infusion over 90 minutes, every two weeks for 2 months. Disease will be reassessed after two cycles. Those with stable disease or better will receive 90 mg every 4 weeks as maintenance therapy.Drug: Thalidomide
All Patients will receive thalidomide 200 mg as an oral, once daily dose. Dose may be reduced to as low as 50 mg qod in the event of severe toxicity. Thalidomide will continue daily as tolerated until criteria to remove from study are met.
Patients will receive appropriate regimen to prevent constipation (i.e., colace, dulcolax, milk of magnesia, or lactulose)
Patients will receive either pamidronate or zometa. Zometa is administered at a dose of 4 mg by continuous infusion every two weeks for 2 months. Disease will be reassessed after two cycles. Those with stable disease or better will receive 4 mg every 4 weeks as maintenance therapy.
