Research Agreements	Research Agreements Abaloparatide-SC Phase 3 Extension Study The Company contracted with Nordic Bioscience Clinical Development VII A/S ("Nordic") to conduct a Phase 3 clinical trial of abaloparatide-SC (the "Phase 3 Clinical Trial"). The Company also contracted with Nordic to perform an extension study to evaluate six months of standard-of-care osteoporosis management following the completion of the Phase 3 Clinical Trial (the "Extension Study"), and, upon completion of this initial six months, an additional period of 18 months of standard-of-care osteoporosis management (the “Second Extension”).
