Licensed Compound means [***].
Back-Up Compound means, with reference to any particular Development Candidate or Drug Product Candidate, a Compound which (a) has the same principal mode of action (i.e., Potentiator or Corrector) as that Development Candidate or Drug Product Candidate; and (b) was among the group of Compounds, identified by VERTEX as potential additional lead molecules having the same principal mode of action, from which the Development Candidate was selected.
Collaboration Compound means any of the following: (a) FG-4592, (b) any HIF Compound (other than FG-4592) that is added to this Agreement pursuant to Section 3.6, and (c) any salts, esters, complexes, chelates, crystalline and amorphous morphic forms, pegylated forms, enantiomers (excluding regioisomers), prodrugs, solvates, metabolites and catabolites of any of the foregoing ((a) or (b)).
Licensed Compounds means: (a) Research Program Active Compounds; (b) Novartis Active Compounds; (c) salts, hydrates, solvates, esters, metabolites, intermediates, stereoisomers and polymorphs of Research Program Active Compounds or Novartis Active Compounds; and (d) prodrugs of Research Program Active Compounds or Novartis Active Compounds (any of the foregoing, a “Licensed Compound”).
Lead Compound means any compound of lead other than galena which, when treated in the manner described below, yields to an aqueous solution of hydrochloric acid, a quantity of soluble lead compound exceeding, when calculated as lead monoxide, five per cent of the “dry weight” of the portion taken for analysis. In the case of paints and similar products and other mixtures containing oil or fat the “dry weight” means the dry weight of the material remaining after the substance has been thoroughly mixed and treated with suitable solvents to remove oil, fats, varnish or other media.
