      <Description>THE ALS THERAPY DEVELOPMENT INSTITUTE SUCCESSFULLY SCREENED A TOTAL OF 20 POTENTIAL TREATMENTS FOR ALS IN 2012. IN FEBRUARY 2012 IT ANNOUNCED A NEW LEAD CANDIDATE IN TDI-132 (GILENYA) AND RAISED $1 MILLION IN 2012 FOR CLINICAL TRIAL TO OCCUR IN 2013. IN MARCH IT MOVED TO THE LARGEST RESEARCH FACILITY IN CAMBRIDGE, MASSACHUSETTS, ADDING ALMOST 10,000 SQ/FT TO ITS LABORATORIES WHICH ENABLED IT TO INCREASE ITS IN VIVO AND IN VITRO VALIDATION CAPABILITIES GREATLY. THE INSTITUTE ENTERED INTO AND COMPLETED SIGNIFICANT ADDITIONAL EXPERIMENTS AS PART OF A RESEARCH AGREEMENT WITH BIOGEN IDEC AND UCB PHARMA ON SECOND CANDIDATE THERAPEUTIC KNOWN AS TDI-846. ALS TDI ALSO ENTERED INTO PARTNERSHIP WITH SWISS BIOTECH, NUEROTUNE AG, ON POTENTIAL TREATMENTS FOR ALS AND A PARTNERSHIP WITH DUTCH BIOTECH, REGENESANCE BV, ON POTENTIAL TREATMENTS FOR ALS; BOTH IN MAY 2012.
