E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients, age ? 18 years, with pathologically confirmed DLBCL whose disease is relapsed and/or refractory, with documented evidence of disease progression after the most recently administered chemotherapy regimen (according to International Working Group (IWG) criteria for progression of lymphoma, Cheson 2007), and who in the opinion of the investigator are not candidates for high-dose chemotherapy with autologous stem cell rescue, may be considered for enrollment. Patients must have received at least 2 but no more than 4 previous systemic multi-agent regimens for the treatment of their DLBCL including at least one course of anthracycline-based chemotherapy (unless absolutely contraindicated due to cardiac dysfunction, in which case etoposide must have been given) and at least two courses of anti-CD20 immunotherapy (e.g., rituximab), unless contraindicated due to severe toxicity. Prior stem cell transplantation is allowed; induction, consolidation, stem cell collection, preparative regimen and transplantation ± maintenance are considered a single line of therapy. Patients should have an estimated life expectancy of more than 3 months at study entry. Patients will undergo a pre-screening biopsy to confirm DLBCL histology, define DLBCL subtype (GCB or non-GCB) as well as DH-DLBCL status (Myc, BCL2, and BCL6 translocation and expression). |
Se podrán considerar para su inclusión los pacientes ? 18 años, con LDCBG confirmado anatomopatológicamente y refractario o recidivante o resistente, que presenten signos documentados de progresión de la enfermedad después del último tratamiento con quimioterapia administrado (según los criterios del International Working Group [IWG] para la progresión del linfoma, Cheson 2007) y, que en opinión del investigador, no sean candidatos para recibir quimioterapia en altas dosis con rescate autólogo de células madre.Los pacientes deberán haber recibido un mínimo de 2 pero no más de 4 politerapias sistémicas previas para el LDCBG incluido, al menos un ciclo de quimioterapia basada en antraciclinas (a menos que estén totalmente contraindicadas debido a insuficiencia cardíaca, en cuyo caso se debe haber administrado un etopósido) y un mínimo de dos ciclos de inmunoterapia con anticuerpos anti-CD20 (p. ej., rituximab), salvo que esté contraindicado debido a toxicidad intensa.Se permite trasplante de células madre previo; la inducción, la consolidación, la recolección de células madre, el tratamiento preparatorio y el trasplante ± el mantenimiento se considerarán una única línea de tratamiento.Los pacientes deberán tener una esperanza de vida estimada superior a 3 meses en el momento de su inclusión en el estudio.Se les realizará una biopsia antes del proceso de selección para confirmar el tipo histológico del LDCBG, definir el subtipo de LDCBG (subtipo CGB o no CGB), y determinar el estado de doble translocación del LDCBG (translocación y expresión de Myc, BCL2 y BCL6). |
|
E.4 | Principal exclusion criteria |
Patients with histologies other than de novo DLBCL, (i.e., patients with DLBCL transformed from indolent lymphomas, primary mediastinal (thymic) large B-cell lymphoma (PMBL), or active central nervous system (CNS) lymphoma, will be excluded from this study. Patients with severe intolerance to glucocorticoids (e.g., due to uncontrolled diabetes mellitus) who are unable to receive a minimum dose of 8 mg of dexamethasone twice weekly (i.e., with each dose of selinexor) are also excluded from this study. Patients must not be eligible for high-dose therapy with stem cell rescue and documentation for ineligibility must be provided. |
Quedarán excluidos del estudio los pacientes con histologías que no sean LDCBG de novo,es decir, los pacientes con LBDCG transformado de linfomas indolentes, linfoma primario mediastínico (tímico) de células B grandes (LPMB) o linfoma del sistema nervioso central (SNC).También quedarán excluidos del estudio los pacientes con intolerancia grave a los glucocorticoides (p. ej., debido a diabetes mellitus no controlada) que no puedan recibir una dosis mínima de 8 mg de dexametasona dos veces a la semana (es decir, con cada dosis de selinexor).Los pacientes no deben ser elegibles para recibir tratamiento en dosis altas con rescate de células madre y deberá facilitarse la documentación en la que se constate que no son elegibles. |
