Quimioterapia combinada, transplante de células-tronco periféricas, terapia biológica, pamidronato e talidomida para mieloma múltiplo

15 de outubro de 2026 atualizado por: City of Hope Medical Center

Alta dose sequencial de melfalano e busulfan/ciclofosfamida seguido de resgate de células progenitoras de sangue periférico, interferon/talidomida e pamidronato para pacientes com mieloma múltiplo

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow doctors to give higher doses of chemotherapy drugs and kill more cancer cells. Biological therapies, such as interferon alfa, use different ways to stimulate the immune system and stop cancer cells from growing. Thalidomide may stop the growth of cancer cells by stopping blood flow to the tumor. Pamidronate may help to reduce the side effects of treatment for multiple myeloma.

PURPOSE: This phase II trial is studying combination chemotherapy, peripheral stem cell transplantation, biological therapy, pamidronate, and thalidomide to see how well they work in treating patients with stage I, stage II, or stage III multiple myeloma.

Descrição detalhada

OBJECTIVES:

  • Determine the feasibility and toxic effects of high-dose melphalan, busulfan, and cyclophosphamide followed by autologous peripheral blood stem cell rescue, interferon alfa, and pamidronate in patients with responsive or stable, low-bulk multiple myeloma.
  • Determine the response rate and progression-free and overall survival of patients treated with this regimen.
  • Determine the feasibility of adding thalidomide to interferon alfa and pamidronate in patients who are not in complete remission (CR) 6 months after the second course of high-dose chemotherapy.
  • Determine whether administration of thalidomide can increase the CR rate in patients who are not in CR 6 months after the second course of high-dose chemotherapy and determine its effect on progression-free and overall survival of these patients.
  • Determine the pharmacokinetics of busulfan and cyclophosphamide and correlate the pharmacokinetics with the toxic effects of these drugs and outcome in these patients.
  • Determine the effect of thalidomide on microvascular density of bone marrow and correlate these possible effects with outcome in these patients.
  • Determine the cytogenetics, gene rearrangement, and fluorescence in situ hybridization in baseline and post treatment bone marrow and blood specimens and correlate the presence/persistence of these features with treatment outcome in these patients.

OUTLINE: Patients receive cyclophosphamide IV over 2 hours on day 1 and filgrastim (G-CSF) subcutaneously (SC) or IV twice a day beginning on day 2 and continuing until peripheral blood stem cells (PBSCs) are collected. PBSCs are collected beginning on day 10.

Patients receive high-dose melphalan IV on day -1. PBSCs are reinfused on day 0. G-CSF is administered IV or SC daily beginning on day 1 and continuing until blood counts recover. Between 8 and 14 weeks later, patients receive high-dose busulfan IV every 6 hours on days -7 to -4 and cyclophosphamide IV over 2 hours on days -3 and -2. PBSCs are reinfused on day 0 and G-CSF is administered IV or SC daily until blood counts recover.

Patients with responding or stable disease after chemotherapy receive maintenance therapy with interferon alfa beginning 14-20 weeks after day 0 of the second course of chemotherapy. Interferon alfa is administered SC 3 times a week for 3 years. Patients also receive pamidronate IV every 4 weeks until disease progression. Patients who are not in complete remission (CR) 6 months after completing the second course of chemotherapy receive oral thalidomide daily for a maximum of 1 year or for 3 months after achieving CR.

Patients are followed monthly for 1 year, every 3 months for 1 year, and then periodically thereafter.

PROJECTED ACCRUAL: A total of 70 patients will be accrued for this study within approximately 2.5 years.
