Halozyme Therapeutics Begins Phase 1 Clinical Trial of Bisphosphonate Administered With rHuP...( SAN DIEGO Dec. 10 /- Halozyme Therape...),Health

SAN DIEGO, Dec. 10 /PRNewswire-FirstCall/ -- Halozyme Therapeutics, Inc. (Nasdaq: HALO), a biopharmaceutical company developing and commercializing products targeting the extracellular matrix for the endocrinology, oncology, dermatology, and drug delivery markets, today announced the commencement of patient dosing for a Phase 1 clinical trial for a bisphosphonate administered with Halozyme's recombinant human hyaluronidase enzyme (rHuPH20) as a subcutaneous (SC) injection. This study will explore the safety, tolerability and pharmacokinetics of SC administration of a bisphosphonate plus rHuPH20. Currently, injectable bisphosphonates must be administered intravenously (IV).

"We are pleased that the first clinical trial is underway for our bisphosphonate program, our third proprietary product development initiative to enter clinical studies," stated Jonathan Lim, M.D., President and CEO of Halozyme Therapeutics. "The bisphosphonate program joins insulin, for diabetes, and Chemophase, for superficial bladder cancer, our other two proprietary programs in clinical development. The goal of Halozyme's bisphosphonate program is to provide an alternative dosage formulation that may offer greater convenience, compliance and tolerability to patients for the treatment of osteoporosis."

This Phase 1 dose ranging clinical trial will assess the safety, tolerability and pharmacokinetics of a bisphosphonate with and without co-administration of rHuPH20 across a range of bisphosphonate concentrations and volumes and various rHuPH20 doses. The study will also compare SC administration of a bisphosphonate plus rHuPH20 to IV bisphosphonate alone.
