ZELOS AND NEKTAR ANNOUNCE START OF PHASE 1 TRIAL OF INHALED OSTABOLIN-C(TM) FOR OSTEOPOROSIS
Zelos Therapeutics, Inc., a private biopharmaceutical company focused on developing novel therapies for patients suffering from osteoporosis, and Nektar Therapeutics (Nasdaq: NKTR) today announced the initiation of a Phase 1 clinical trial of an inhaled powder formulation of Zelos' proprietary parathyroid hormone Ostabolin-C(TM) (cyclic PTH-(1-31)). Nektar and Zelos entered into a collaboration to develop an inhaleable powder form of Ostabolin-C in January 2005.
"Ostabolin-C is a powerful new bone formation agent that we believe will emerge as a best-in-class PTH for the treatment of osteoporosis. A key to expanding the market for bone formation therapies will be the development of convenient non-injectable delivery alternatives that can improve both patient compliance and thus, treatment outcomes in osteoporosis," commented Brian MacDonald, MB, ChB, PhD, chief executive officer of Zelos. "Our strategy is to evaluate several delivery options for Ostabolin-C and we are pleased to advance this promising inhaled version of Ostabolin-C into the clinic with our partner Nektar."
"This product has the potential to address the need for a more convenient, patient-friendly and much-needed therapy option for osteoporosis patients," said David Johnston, senior vice president of research and development at Nektar. "Inhaled Ostabolin-C uses Nektar's small, pocket-sized inhaler to deliver a peptide and it is designed to provide a portable and easy-to-use solution for patients."
About the Study
The Phase 1 trial is a single-center randomized, double blind, placebo-controlled, escalating-dose study that will enroll up to 56 healthy postmenopausal women. The study will evaluate 28 days of dosing. The dry powder formulation of Ostabolin-C will be administered using Nektar's convenient, pocket-sized dry powder inhaler. The primary study endpoints are the safety and tolerability of single and repeated doses of inhaled Ostabolin-C. In addition, the study will evaluate the pharmacokinetics and pharmacodynamics of inhaled Ostabolin-C, as well as the effect of inhaled Ostabolin-C on serum markers of bone formation and resorption. The Phase 1 trial includes a sub-study to compare the pharmacokinetic characteristics of a single dose of Ostabolin-C given via a subcutaneous (SC) injection and a single dose of inhaled Ostabolin-C.
About Ostabolin-C
Ostabolin-C, a cyclic 1-31 amino acid analog of parathyroid hormone (PTH), is a bone formation agent designed to improve upon the safety and efficacy of current therapies in the large and rapidly growing osteoporosis market. Preclinical and Phase 1 studies have shown that Ostabolin-C stimulates significant bone formation with little to no stimulation of bone resorption. Due to the minimized bone resorption, Ostabolin-C demonstrates a reduced potential to cause hypercalcaemia, a common side effect of current PTH therapies. With this profile, Ostabolin-C may become a best-in-class compound in the growing PTH market and a leading therapy in the treatment of osteoporosis. Zelos is currently conducting Phase 2 clinical studies with Ostabolin-C as a once-daily, self-administered subcutaneous injection.
To address the need for more convenient and patient-friendly non-injectable delivery, Nektar and Zelos are partnered for the development of an inhaled formulation of Ostabolin-C. Nektar's Advanced Pulmonary Technology is designed to provide an integrated inhalation system that disperses fine, dry, respirable powders in a reproducible fashion for optimal systemic delivery.
