The Company is developing products to expand its angioedema portfolio, including a therapeutic candidate, DX-2930, for the prophylactic treatment of HAE and a biomarker assay to identify plasma- kallikrein-mediated disorders. In August 2013, Dyax began a Phase 1 clinical study evaluating the safety and tolerability of single subcutaneous administration of DX-2930 in healthy subjects.KALBITOR and DX-2930 were identified using Dyax's patented phage display technology, which rapidly selects compounds that bind with high affinity and specificity to therapeutic targets. Dyax leverages this technology broadly through the LFRP. This program has provided the Company a portfolio of product candidates being developed by its licensees, which currently includes 13 revenue eligible product candidates in various stages of clinical development, including three in Phase 3 trials.
