ENHANZE® Drug Delivery Technology
Bristol Myers Squibb
ENHANZE technology helps break through subcutaneous volume limitations to facilitate rapid high-dose, high-volume subcutaneous drug delivery.
Improved Patient Experience
Health Systems Efficiencies
Optimized Product Profile
Our ENHANZE technology is based on our patented recombinant human hyaluronidase PH20 enzyme, rHuPH20, which locally degrades hyaluronan (HA) in the subcutaneous (SC) space temporarily removing a barrier to fluid flow. This allows for large volume SC injection with increased dispersion and absorption of co-administered therapies.
Potential Benefits of Co-Formulation With ENHANZE Technology
Large volume injections may allow some biologics and small molecule drugs that are administered intravenously to be delivered subcutaneously, opening the door to potential benefits for patients, healthcare systems and manufacturers.

About rHuPH20
Halozyme’s primary technology is based on its proprietary recombinant human hyaluronidase PH20 enzyme (rHuPH20) that degrades hyaluronan, or HA. HA is a glycosaminoglycan, a chain of natural sugars that is a component of normal tissue, such as skin and cartilage.
The effects of rHuPH20 are local and transient. By degrading HA, rHuPH20 facilitates the dispersion and absorption of other drugs and fluids that are injected under the skin.
HA IN THE SUBCUTANEOUS SPACE
What is Hyaluronan?
Hyaluronan (HA) is a megadalton polymeric glycosaminoglycan made up of repeating disaccharide subunits of N-acetylglucosamine and glucuronic acid. It is found in most tissues and body fluids of vertebrates, but is most abundant in the extracellular matrix of connective tissues. High concentrations of HA can be found in tissues, such as the skin, umbilical cord, synovial fluid and vitreous humour. HA is rapidly turned over in normal skin with a half-life of less than two days, but relatively constant levels are maintained by similar rates of synthesis and degradation.
In skin, HA fills the interstitial space within the collagenous matrix and acts as a physical barrier to bulk fluid flow in the subcutaneous space. It does this by binding up to 15 water molecules per disaccharide subunit forming a viscous gel-like fluid. This gel-like HA limits fluid flow in the subcutaneous space, acts as a lubricant in other compartments, such as the synovial fluid within joints, and functions as a viscoelastic cushion to protect tissues and joints. In addition, HA may be involved in various receptor-mediated cell signaling events with proposed roles in areas, such as cell detachment, wound healing, cell migration, inflammation, and tumor development.
