ABSTRACT: A phase 2 trial was performed to study the combination of bortezomib (VELCADE) with intermediate-dose dexamethasone (DEX), and continuous low-dose oral cyclophosphamide (CY) in patients with relapsed multiple myeloma (MM). Fifty-four patients with advanced MM were enroled to receive eight 3-week treatment cycles with bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11, followed by three 5-week cycles with bortezomib 1.3 mg/m(2) on days 1, 8, 15, and 22. Within all cycles, DEX 20 mg/d was given orally on the day of bortezomib injection and the day thereafter. In addition, patients received CY continuous oral treatment at a dose of 50 mg/d p.o. once daily. Fifty patients completing at least one treatment cycle were evaluable for response. Complete, partial, and minor responses occurred in 16%, 66% and 8% of patients, respectively; overall response rate 90% (efficacy analysis). Median event-free survival was 12 months, with a median overall survival of 22 months. Adverse events (AE) of grades 3 or 4 occurring in at least 10% of patients comprised leucopenia, infection, herpes zoster, thrombocytopenia, neuropathy and fatigue. Bortezomib combined with DEX and CY is a highly effective treatment for relapsed MM at an acceptable rate of grade 3/4 AE. Antiviral prophylaxis appears to be mandatory.British Journal of Haematology 09/2007; 138(3):330-7. · 4.94 Impact Factor

ABSTRACT: Multiple myeloma is an incurable disease and after several lines of chemotherapy, patients enter a phase in which no standard treatment options are available. The poor outlook of these patients requires mild, palliative therapy with low toxicity. Previously used regimens either require frequent hospital attendance, lack efficacy or have significant toxicity. In the current study, daily low dose, oral cyclophosphamide (100 mg) and prednisone (10-20 mg; CP) were administered to patients with advanced myeloma. Forty-two patients with progressive disease after melphalan-based and VAD treatment were enrolled. Objective responses were observed in 29 of 42 (69%) patients. In responding patients, median overall survival and progression-free survival were 22.2 months and 15.0 months, respectively. In non-responders, median OS was 3.5 months only. Side-effects were limited. Cytopenia was the most frequent event (8/29) prompting dose reduction. CP had to be stopped permanently in four patients (two cytopenia, two infections). Orally administered, low dose continuous CP is a feasible, effective and well-tolerated regimen in the management of advanced multiple myeloma.The Netherlands Journal of Medicine 09/2001; 59(2):50-6. · 2.38 Impact Factor
