Abstract/OtherAbstract:
Background. Mantle cell lymphoma accounts for 6% of all B-cell lymphomas and is generally incurable. It is characterized by the translocation t(11;14) leading to Cyclin D1 over-expression. Cyclin D1 is downstream of the mammalian target of rapamycin (mTOR) threonine kinase and can be effectively blocked by mTOR inhibitors. We set out to examine the single agent activity of the orally available mTOR inhibitor everolimus in a prospective, multicentre trial in patients with relapsed or refractory relapsed or refractory mantle cell lymphoma (NCT00516412).Design and Methods. Eligible patients with a maximum of 3 prior lines of chemotherapy received everolimus 10 mg for 28 days (one cycle) for a total of 6 cycles or until disease progression. Primary endpoint was the best objective response. Adverse reactions, progression free survival and molecular response were secondary endpoints.Results. 36 patients (35 evaluable) were enrolled and treatment was generally well tolerated with CTC grade ≥3 adverse events (>5%) included anemia (11%), thrombocytopenia (11%) and neutropenia (8%). Overall response rate was 20% (95% CI: 8-37%) with 2 complete remissions and 5 partial responses, with additionally stable disease 49%. At median follow-up of 6 months, median progression free survival was 5.5 months (95% CI: 2.8-8.2) overall and 17.0 (6.4-23.3) months for 18 patients receiving ≥6 cycles of treatment. Three patients achieved a lasting complete molecular response when assessed in the peripheral blood by PCR. Conclusions. Single agent everolimus is well tolerated and has anti-lymphoma activity in relapsed or refractory mantle cell lymphoma. Further studies of everolimus either in combination with chemotherapy or as single agent for maintenance treatment are warranted.clinicaltrials.gov identifier: NCT00516412.
