Summary

A Multi-center study to determine effects of various doses of Macroflux PTH in women with osteoporosis

Clinical Details

Official title: A Dose Ranging Study of the Effects of Macroflux« PTH Compared With Macroflux« Placebo and FORTEO« in Postmenopausal Women With Osteoporosis

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: To determine the effect of 3 doses of Macroflux® human parathyroid hormone (1-34) (PTH) administered for 24 weeks on lumbar spine bone mineral density (BMD) compared to Macroflux® placebo.

Secondary outcome:

To determine the systemic and topical safety of 3 doses of Macroflux® PTH, self administered daily for 24 weeks in postmenopausal women with osteoporosis compared to Macroflux® placebo and FORTEO®;

To compare the pharmacokinetics of 3 doses of Macroflux® PTH to FORTEO®

To evaluate the effect of three doses of Macroflux® PTH on total hip, femoral neck and forearm BMD relative to placebo and FORTEO®

To determine the effect of 3 doses of Macroflux® PTH administered on serum procollagen 1 N-terminal propeptide (P1NP) and serum C-terminal cross-linking telopeptide of type 1 collagen (CTX)compared to Macroflux® placebo

- Have osteoporosis defined as: Either a T-score of ÔëĄ -2. 5 at the lumbar spine,

femoral neck, or total hip, AND a T-score of at least < - 1. 0 at the lumbar spine; or

A T-score of ÔëĄ - 2. 0 at the lumbar spine, femoral neck, or total hip, AND at least one

exception of squamous or basal cell carcinoma of the skin in which the lesions were fully resected with clear margins described in a written report by a pathologist, and the patient has had no recurrence of lesions for at least 1 year from the time of original resection;

- Any condition or disease that may interfere with the ability to have or the

evaluation of a DXA scan, for example, severe osteoarthritis of the spine, spinal fusion, pedicle screws, history of vertebroplasty, or degenerative disease that results in insufficient number of evaluable lumbar vertebrae, or >1 lumbar vertebral fracture in L1-L4;

- More than 4 vertebral fractures in T4-L4;

- Bilateral hip replacements;

- Use of fluoride (e. g. fluoride therapy for osteoporosis) or strontium at any time;

activity;

assessments, or with a history of contact dermatitis;

- With known allergy or sensitivity to tapes, adhesives, PTH, teriparatide or its

analogs, or components of the Macroflux® systems;

- Who, in the opinion of the investigator, should not participate in the study, or may

not be capable of following the study schedule for any reason; and

- Unwillingness or inability to abide by the requirements of the study.

- Have received any intravenous (IV) administered bisphosphonates in the past 24

months, or >2 doses of IV administered bisphosphonates total;

- Use of oral bisphosphonates before randomization, including investigational

bisphosphonates, unless: <6 months of treatment and off for 6 months, or 6-12 months of treatment and off for 2 years, or >12 months of treatment and off for 5 years;
