• Cimzia (certolizumab) - UCB: Although not developed forthe treatment of fistulizing Crohn directly, fistula healing wasa secondary endpoint in one of Cimzia’s maintenance trials(PRECISE 1) and a small number of patients in PRECISE 2 alsohad fistula as a baseline. In none of the two trials did Cimziaoutperform efficacy of placebo.• Tysabri (natalizumab) – Elan-Biogen: Approved by the FDAfor the treatment of moderate to severe Crohn’s disease.However, Tysabri is not effective in the treatment offistulizing Crohn’s disease and the ENACT-1, ENACT-2 andENCORE trials all specifically excluded patients with activefistulae.Biologicals are currently also the standard of care for thetreatment of a large number of autoimmune-mediatedinflammatory diseases, including Rheumatoid Arthritis.However, and although a number of products are availabletoday for the treatment of RA, the lack of efficacy of biologicaltreatments in some patients, the non-tolerability or recurrentsecondary infections and the adverse effects from currentantirheumatic medication are widely documented andcontribute to the need of developing new therapies.Stem cell companiesAs a result of the significant promise of cell therapy, there aremore than 100 companies currently developing stem cells asa therapeutic modality to treat diseases. They can be broadlycategorized according to the following diagram:Fig. 6.10: Categorization of companies developing stem cells as a therapeutic modality to treat diseasesCellerix uses allogeneic expanded adult stem cells astherapeutic agent and bases its developments on the immunemodulatorycapacity of the stem cells (vs. differentiation intoother tissue types).Other clinical stage stem cell companies currently pursuing asimilar approach in terms of tissue source and mechanism ofaction are:• Celgene Cellular Therapeutics (USA): Celgene’s stemcell therapy business, which begun in 2002 through theacquisition of Anthrogenesis; The company is developinga platform around PDA-001, a placenta-derived expandedstem cell population; Clinical development focus is onimmune-mediated inflammatory diseases and ischemicstroke; A positive safety profile of PDA001 has beendemonstrated in a Phase I trial in Crohn´s.148 • <strong>TiGenix</strong> • Rights Offering
