German CLL Study Group

Also called: Deutsche CLL StudiengruppeDCLLSGGCLLSG
Overview
The Deutsche CLL Studiengruppe (DCLLSG, German CLL Study Group) was founded in 1996 to improve the diagnosis and treatment of chronic lymphocytic leukaemia through controlled prospective trials, and describes itself as a research organisation of the University of Cologne specialising in CLL (dcllsg.de). ClinicalTrials.gov names it lead sponsor (OTHER class) of CLL12 (NCT02863718, phase 3, ibrutinib against placebo in early-stage CLL, with Janssen-Cilag as collaborator) and of CLL13 / GAIA (NCT02950051, phase 3, venetoclax combinations against chemoimmunotherapy in fit treatment-naive CLL, with Janssen-Cilag, Roche, AbbVie, HOVON, the Nordic CLL Study Group and others as collaborators); on CLL14 (NCT02242942, venetoclax and obinutuzumab in unfit CLL) the registry lead is Hoffmann-La Roche and the group is a collaborator, as the OnCo record's sponsor line says. It has no products of its own.
