The American Society of Hematology meeting closed yesterday and served to shine the light on the latest research and progress of new therapies targeting hematological malignancies as well as other serious blood disorders.

After dropping to its lowest valuation at the end of September, the BioWorld Neurological Diseases index, a price-weighted index of public biopharmaceutical companies that are focused on developing therapies to treat neurological diseases, got on a roll and climbed 22% during the next two months. However, a surprising trial failure reported by Sage Therapeutics Inc. last week served to eat into those index gains.
