      <Description>ALS TDI EXECUTED MORE THAN 45 DIFFERENT PROGRAMS IN 2011 ON A VARIETY OF DIFFERENT TARGETS THAT IT IDENTIFIED TO BE HIGHLY RELEVANT TO ALS DISEASE PROGRESSION. THESE PROGRAMS MOVED THROUGH VARIOUS POINTS OF THE DRUG DEVELOPMENT PIPELINE; FROM HIT OPTIMIZATION, IN VITRO ASSAY DEVELOPMENT AND VALIDATION, TO IN VIVO PHAMACOKINETICS AND PHARMACODYNAMICS, THROUGH EFFICACY STUDIES IN ALS ANIMAL MODELS. TWO OF THESE PROJECTS, TDI 846 AND TDI 132, WERE IDENTIFIED AS LEAD CANDIDATE THERAPEUTICS AND POSITIONED BY THE INSTITUTE FOR CLINICAL DEVELOPMENT. TDI 846 WAS PARTNERED WITH BIOGEN IDEC AND UCB PHARMA IN DECEMBER FOR CLINICAL DEVELOPMENT. TDI 132 WAS SLATED FOR ADVANCEMENT TO THE CLINIC INDEPENDENTLY IN 2012 AS WELL. THE INSTITUTE ALSO LAUNCHED A NEW WEBSITE IN 2012 WHICH INCREASED ITS SCIENTIFIC TRANSPARENCY, UPDATED ITS ONLINE ALS FORUM, AND CREATED A NEW ONLINE JOURNAL CALLED ALS TODAY WRITTEN BY SCIENTIFIC JOURNALISTS. IT COLLABORATED WITH MORE THAN A DOZEN ACADEMIC AND INDUSTRIAL PARTNERS ON THERAPEUTIC-AIMED PROJECTS.
