r-hGH Liquid Multidose Versus Freeze-dried Multidose Bioequivalence Trial
The primary objective of the trial was to assess the bioequivalence for two concentrations (5.83 mg/mL and 8 mg/mL) of the new r-hGH liquid multidose formulation using the r hGH freeze-dried multidose formulation (Saizen® 8 mg, 8.8 mg/1.51 mL) as reference.
Each volunteer received three r hGH treatments, with each treatment being administered as a single subcutaneous dose of 4 mg r-hGH in a randomized sequence with at least one week of wash-out period between successive treatments.
Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science

Medical and Biotech [MESH] Definitions
A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)
A replica technique in which cells are frozen to a very low temperature and cracked with a knife blade to expose the interior surfaces of the cells or cell membranes. The cracked cell surfaces are then freeze-dried to expose their constituents. The surfaces are now ready for shadowing to be viewed using an electron microscope. This method differs from freeze-fracturing in that no cryoprotectant is used and, thus, allows for the sublimation of water during the freeze-drying process to etch the surfaces.
Chromatographic techniques in which the mobile phase is a liquid.
Materials in intermediate state between solid and liquid.
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
