A Study of MabThera (Rituximab) Plus Chlorambucil in Patients With Previously Untreated Chronic Lymphocytic Leukemia.

6. juli 2017 opdateret af: Hoffmann-La Roche

A Study of Chlorambucil Plus MabThera as Induction Therapy Followed in Responders by Maintenance Therapy Versus Observation on Response Rate in Patients >=60 Years With Previously Untreated Chronic Lymphocytic Leukemia

This single arm study will assess the efficacy and safety of MabThera + chlorambucil as induction therapy, followed in responders by maintenance therapy or observation in elderly patients with previously untreated chronic lymphocytic leukemia. During the induction phase patients will receive 2 x 4 weekly courses of chlorambucil followed by 8 x 4 weekly courses of chlorambucil + MabThera. Subsequently, responders will be randomized to receive 12 doses of MabThera given every 8 weeks, or no further treatment. The anticipated time on study treatment is 2+ years, and the target sample size is <100 individuals.

Deltagelseskriterier

Forskere leder efter personer, der passer til en bestemt beskrivelse, kaldet berettigelseskriterier. Nogle eksempler på disse kriterier er en persons generelle helbredstilstand eller tidligere behandlinger.

Berettigelseskriterier

Berettigelseskriterier

De nøglekrav, som personer, der ønsker at deltage i et klinisk studie, skal opfylde eller de egenskaber, de skal have. Kvalifikationskriterier består af både inklusionskriterier (som er nødvendige for at en person kan deltage i undersøgelsen) og eksklusionskriterier (som forhindrer en person i at deltage).
