BACKGROUND: Patients with myeloma who relapse after high-dose chemotherapy have few therapeutic options. Since increased bone marrow vascularity imparts a poor prognosis in myeloma, we evaluated the efficacy of thalidomide, which has antiangiogenic properties, in patients with refractory disease. METHODS: Eighty-four previously treated patients with refractory myeloma (76 with a relapse after high-dose chemotherapy) received oral thalidomide as a single agent for a median of 80 days (range, 2 to 465). The starting dose was 200 mg daily, and the dose was increased by 200 mg every two weeks until it reached 800 mg per day. Response was assessed on the basis of a reduction of the myeloma protein in serum or Bence Jones protein in urine that lasted for at least six weeks. RESULTS: The serum or urine levels of paraprotein were reduced by at least 90 percent in eight patients (two had a complete remission), at least 75 percent in six patients, at least 50 percent in seven patients, and at least 25 percent in six patients, for a total rate of response of 32 percent. Reductions in the paraprotein levels were apparent within two months in 78 percent of the patients with a response and were associated with decreased numbers of plasma cells in bone marrow and increased hemoglobin levels. The microvascular density of bone marrow did not change significantly in patients with a response. At least one third of the patients had mild or moderate constipation, weakness or fatigue, or somnolence. More severe adverse effects were infrequent (occurring in less than 10 percent of patients), and hematologic effects were rare. As of the most recent follow-up, 36 patients had died (30 with no response and 6 with a response). After 12 months of follow-up, Kaplan-Meier estimates of the mean (+/-SE) rates of event-free survival and overall survival for all patients were 22+/-5 percent and 58+/-5 percent, respectively. CONCLUSIONS: Thalidomide is active against advanced myeloma. It can induce marked and durable responses in some patients with multiple myeloma, including those who relapse after high-dose chemotherapy Bruno B, Rotta M, and Boccadoro M, Lancet Oncology 2004, in Press DIVISIONE UNIVERSITARIA DI EMATOLOGIA AZIENDA OSPEDALIERA SAN GIOVANNI TORINO, ITALY Thalidomide: mechanism of action ?? “Thal metabolism required for its anti-myeloma efficacy” Human myeloma Human liver Thal Human myeloma reduced Thal ~ unchanged Yaccoby et Al, Blood, 2002 DIVISIONE UNIVERSITARIA DI EMATOLOGIA AZIENDA OSPEDALIERA SAN GIOVANNI TORINO, ITALY GRUPPO ITALIANO PER LO STUDIO DEL MIELOMA MULTIPLO INTERIM ANALYSIS PROSPECTIVE RANDOMIZED TRIAL NEWLY DIAGNOSED PATIENTS, AGE > 65 YEARS MELPHALAN, PREDNISONE + THALIDOMIDE (MPT) versus MELPHALAN PREDNISONE (MP) DIVISIONE UNIVERSITARIA DI EMATOLOGIA AZIENDA OSPEDALIERA SAN GIOVANNI TORINO, ITALY ADVERSE EVENTS MP MPT WHO (grade) Hematologic (%) Constipation (%) Neurologic (%) Cardiac (%) Cutaneous (%) Infection (%) Thromboemb.(%) Early death (%) 1-2 3-4 1-2 3-4 29 28 32 17 15 14 18 7 9 3 2 10 35 11 3 3 12 25 4 1 19 5 4 5 DIVISIONE UNIVERSITARIA DI EMATOLOGIA AZIENDA OSPEDALIERA SAN GIOVANNI TORINO, ITALY RESPONSE TO THERAPY 100 80 77.1% 15.6% 60 40 20 33.8% 46.7% 28% 27.7% PR (50-74) PR (75-99) CR + nCR 13.3% 5.4% 0 MPT MP Dept.
