Recombinant human hyaluronidase PH20 · 4 trials · 4 indications
Glycosylated hemoglobin A1C (HBA1c) levels were measured at baseline (Week 0) and at the end of each treatment period (Week 12 and Week 24). Data are presented by combined treatment group (Lispro-PH20 + Aspart-PH20 = Analog-PH20) and combined comparator drug (Insulin Lispro from both cohorts). Least Squares (LS) means were calculated from mixed effects linear models with treatment (Lispro, Aspart), recombinant human hyaluronidase PH20 (rHuPH20; yes, no), and treatment sequence as fixed effects and participant within treatment sequence as a random effect.
Early insulin exposure, defined as the percentage of total insulin exposure (area under the insulin concentration curve \[AUC{0-360}\]) that occurs within the first hour following bolus dose of insulin during the 2 euglycemic clamps is presented. Blood samples were collected 10 minutes predose and at 0, 5, 10, 15, 20, 30, 45, 60, 120, 150, 180, 240, 300, and 360 minutes postdose during the euglycemic clamp.

Area under the concentration (AUC)-time curve was derived as the area under the serum insulin concentration profile from 0 to 60 minutes. Blood samples were taken 30, 20, and 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); and at 20, 25, 30, 45, and 60 mins after each injection.

Recombinant human hyaluronidase PH20 is being studied for use in diabetes mellitus, including Type 1 and Type 2 diabetes, as well as in healthy volunteers. It is administered subcutaneously with insulin analogs to potentially improve their pharmacokinetic and glucodynamic profiles. The drug is currently in Phase 2 clinical development.
Recombinant human hyaluronidase PH20 targets hyaluronan, a component of the extracellular matrix. By breaking down hyaluronan, it temporarily increases tissue permeability, which may enhance the absorption and dispersion of co-administered subcutaneous insulin analogs. This mechanism is being evaluated to potentially improve insulin action in diabetic patients.
Recombinant human hyaluronidase PH20 is being developed by Halozyme Therapeutics, Inc., a biopharmaceutical company traded on NASDAQ under the ticker HALO. The company is conducting clinical trials to evaluate the drug's safety and efficacy in combination with insulin analogs for diabetes management.
Recombinant human hyaluronidase PH20 is in Phase 2 clinical development. It has completed Phase 1 and Phase 2 trials, including studies in healthy volunteers and patients with Type 1 and Type 2 diabetes. The drug remains investigational and has not been approved by regulatory authorities.
Recombinant human hyaluronidase PH20 has been studied in several completed trials, including NCT00979875 (Phase 1, healthy volunteers), NCT01194245 (Phase 2, Type 1 diabetes), NCT01194258 (Phase 2, Type 2 diabetes), and NCT01275131 (Phase 1, Type 1 diabetes). These trials evaluated subcutaneous insulin analogs with rHuPH20 compared to insulin analogs alone.
Yes, Recombinant human hyaluronidase PH20 is also known as rHuPH20. In clinical trials, it is often referred to as rHuPH20 when combined with insulin analogs. This naming is used in study titles and descriptions to identify the recombinant human hyaluronidase enzyme being tested.
