Induction with oral chemotherapy (CID) followed by early autologous stem cell transplantation for de novo multiple myeloma patients

In an effort to minimise induction therapy-related toxicity, avoid unnecessary hospitalisation and facilitate early ASCT, we have prospectively evaluated an outpatient-based oral chemotherapeutic regimen, cyclophosphamide, idarubicin, dexamethasone (CID) in patients with previously untreated multiple myeloma (mm). Patients subsequently underwent ASCT conditioned with melphalan 200 g/m(2). A total of 36 newly diagnosed MM patients were enrolled between February 1997 and March 2000. In all 136 cycles of CID were administered requiring only four unplanned hospital admissions. Grade 3 or 4 haematological toxicities were documented following 14 cycles (10%). There were no treatment-related deaths. Response rates (PR + CR) based on an intention-to-treat basis were 66% (23 of 35, 9% CR) post-CID and 80% (28 of 35, 34% CR) post-ASCT. In all, 28 of the 35 patients remain alive with a median follow-up for surviving patients of 40 months (range, 30-67 months). Progression-free survival from the time of diagnosis was 32 months (range, 3-55 + months). Median overall survival from diagnosis has not been reached with an estimated overall survival at 4 years of 77%. CID in combination with early ASCT is an effective and well-tolerated antimyelomatous regimen and is a practical alternative to more toxic and invasive therapeutic approaches

A randomized, open-label, multicentre, phase 2/3 study to evaluate the safety and efficacy of lumiliximab in combination with fludarabine, cyclophosphamide and rituximab versus fludarabine, cyclophosphamide and rituximab alone in subjects with relapsed chronic lymphocytic leukaemia

Lumiliximab is a chimeric monoclonal antibody that targets CD23 on the surface of chronic lymphocytic leukaemia (CLL) B-cells. Early phase clinical studies with lumiliximab alone and in combination with fludarabine, cyclophosphamide and rituximab (FCR) established its potential efficacy and tolerability. The 152CL201 trial [Lumiliximab with fludarabine, cyclophosphamide and rituximab (FCR) versus FCR alone in subjects with relapsed CLL; LUCID] was a phase 2/3, randomized (1:1), open-label, multicentre study of lumiliximab in combination with FCR versus FCR alone in patients with relapsed CLL. Six hundred and twenty-seven patients were randomized to either arm. Overall the combination of lumiliximab with FCR was not significantly better than FCR alone (overall response rate 71% vs. 72%, complete response rate 16% vs. 15%, median progression-free survival 24.6 vs. 23.9 months respectively, for FCR with and without lumiliximab). There was a slightly increased incidence of adverse events with lumiliximab but these increases did not appear to lead to differences in eventual outcomes. An interim analysis failed to show sufficient efficacy of the combination of lumiliximab with FCR. The study was therefore stopped early for lack of efficacy. Despite the eventual outcome, the LUCID trial is one of the largest studies that provides valuable insight into the efficacy and tolerability of FCR as a therapeutic option for patients with relapsed CLL.Farrukh T.

Idarubicin dose escalation during consolidation therapy for adult acute myeloid leukemia

Purpose: Higher doses of the anthracycline daunorubicin during induction therapy for acute myeloid leukemia (AML) have been shown to improve remission rates and survival. We hypothesized that improvements in outcomes in adult AML may be further achieved by increased anthracycline dose during consolidation therapy. Patients and Methods: Patients with AML in complete remission after induction therapy were randomly assigned to receive two cycles of consolidation therapy with cytarabine 100 mg/m2 daily for 5 days, etoposide 75 mg/m2 daily for 5 days, and idarubicin 9 mg/m2 daily for either 2 or 3 days (standard and intensive arms, respectively). The primary end point was leukemia-free survival (LFS). Results: Two hundred ninety-three patients 16 to 60 years of age, excluding those with core binding factor AML and acute promyelocytic leukemia, were randomly assigned to treatment groups (146 to the standard arm and 147 to the intensive arm). Both groups were balanced for age, karyotypic risk, and FLT3-internal tandem duplication and NPM1 gene mutations. One hundred twenty patients in the standard arm (82%) and 95 patients in the intensive arm (65%) completed planned consolidation (P v 35% [95% CI, 28% to 44%]; P = .045). At 5 years, the overall survival rate was 57% in the intensive arm and 47% in the standard arm (P = .092). There was no evidence of selective benefit of intensive consolidation within the cytogenetic or FLT3-internal tandem duplication and NPM1 gene mutation subgroups. Conclusion: An increased cumulative dose of idarubicin during consolidation therapy for adult AML resulted in improved LFS, without increased nonhematologic toxicity
