A Study for the Transdermal Application of Teriparatide

Phase 2

Completed

• Conditions: Osteoporosis
• Interventions: Drug: Subcutaneous Teriparatide; Drug: Transdermal Teriparatide

• Registration Number: NCT01011556
• Lead Sponsor: Eli Lilly and Company

Brief Summary

The primary purpose of this study is to help answer the following research questions:

1. How teriparatide given using a skin patch (transferred through the skin using the ViaDerm Teriparatide System) compares to teriparatide injected under the skin with a needle (pen injector) affects your bone density (how solid or porous your bones are).

2. The safety of the teriparatide skin patch and any side effects that might be associated with it.

Detailed Description

Teriparatide 20 micrograms (mcg) per day is currently only available as a subcutaneous (SQ) injection and many patients with severe osteoporosis for whom anabolic therapy with teriparatide is appropriate are either unwilling or physically unable to self-inject. The purpose of this Phase 2 study is to identify a transdermal dose or doses that will be comparable to the teriparatide 20 mcg SQ dose from a pharmacodynamic (PD) and safety standpoint for use in future Phase 3 studies.

Arm && Interventions

Group	Intervention	Description
20 mcg Subcutaneous Teriparatide	Subcutaneous Teriparatide	Received 20 micrograms (mcg) subcutaneously once daily in an unblinded manner.
30 mcg Transdermal Teriparatide	Transdermal Teriparatide	Received 30 micrograms (mcg) teriparatide transdermally via a patch applied once daily. Participants were blinded to dose level.
50 mcg Transdermal Teriparatide	Transdermal Teriparatide	Received 50 micrograms (mcg) teriparatide transdermally via a patch applied once daily. Participants were blinded to dose level.

Primary Outcome Measures

Name	Time	Method
Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at 12 Months	Baseline, 12 Months	Bone mineral density (BMD) of the lumbar spine was assessed by dual energy X-ray absorptiometry (DXA). BMD values are corrected data and have been standardized across the machine types (Hologic and Lunar). Analyses were performed using ANCOVA model and least square (LS) means were adjusted for baseline BMD values as a covariate and pooled site and treatment as fixed effects.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Urine Calcium Excretion at 6 and 12 Months	Baseline, 6 Months, 12 Months
Change From Pre-dose to Postdose in Supine and Standing Heart Rate at Baseline (BL) and 12 Months (Mon).	Pre-dose, 30 minutes, 2 hours at Baseline and 12 Months
DRAIZE Edema Assessment at Baseline Through 13 Month Follow-up	13 Month follow-up	Severity of edema was categorized based on a 5 point scale: 0=no edema, 4=severe edema (defined as an area raised more than 1 millimeter and extending beyond area of exposure)
Change From Pre-dose and Postdose Supine and Standing SBP and DBP at Baseline (BL) and 12 Months (Mon)	Pre-Dose, 30 minutes, 2 hours Post-Dose at Baseline and 12 Months	Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) measured at pre-dose and 30 minutes (min) and 2 hours (hr) post-dose in both the supine and standing position.
Time Course Change of BMD Response at the Lumbar Spine	Baseline to 6 Months and 12 Months	To assess the time course of the treatment, the BMD data of the lumbar spine was assessed by dual energy X-ray absorptiometry (DXA) and analyzed using a mixed model repeated measures (MMRM) method, with the repeated measure occurring at each visit (for example, 6 and 12 month). BMD values are corrected data and have been standardized across the machine types (Hologic and Lunar).
Percent Change From Baseline of C-Terminal Telopeptide (CTX)	Baseline, 1 Month, 3 Months, 6 Months, 12 Months	C-terminal telopeptide is a marker of bone resorption.
Change in Serum Calcium With and Without Adjustments for Serum Albumin From Predose to After 4 and 6 Hours	Baseline, 12 Months	Serum calcium adjusted for serum albumin levels is calculated using the following formula: Total Calcium + \[(40 - albumin) x 0.02\]. Analysis for serum calcium and albumin adjusted serum calcium were collected at predose, 4 hours (h) post-dose (PD) and 6 h PD at baseline and 12 months (mon).
Pharmacokinetics Parameters: Area Under the Curve (AUC)	Baseline, 1 Month, 3 Months, and 12 Months	Due to high intra-subject variability, data was not analyzed for this outcome measure.
Pharmacokinetics Parameters: Maximal Concentration (Cmax)	Baseline, 1 Month, 3 Months, 12 Months	Due to high intra-subject variability, data was not analyzed for this outcome measure.
Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at 6 Months	Baseline, 6 Months	Bone mineral density (BMD) of the lumbar spine was assessed by dual energy X-ray absorptiometry (DXA). BMD values are corrected data and have been standardized across the machine types (Hologic and Lunar). Analyses were performed using ANCOVA model with the baseline value as a covariate and pooled site and treatment as fixed effects.
Percent Change From Baseline in Procollagen Type 1 N-Terminal Propeptide (P1NP)	Baseline, 1 Month, 3 Months, 6 Months, 12 Months	Procollagen Type 1 N-Terminal Propeptide (P1NP) is a marker of bone formation.
Percent Change From Baseline in Serum Procollagen Type 1 C-Propeptide (P1CP) at 1 Month	Baseline, 1 Month	Procollagen Type 1 N-Terminal Propeptide (P1NP) is a marker of bone formation.
Convenience/Ease of Use Questionnaire (CEUQ)	baseline up to 12 months	CEUQ consists of 5 sections and 16 questions using a 5-point Likert scale designed to collect measures for ease of use (S1), convenience of use (S2), confidence of use (S3), fear of use (S4), and overall satisfaction with therapy (S5). CEUQ is not a validated instrument.
Number of Participants With Parathyroid Hormone (PTH) Specific Antibody Levels	Baseline and 1, 3, 12, and 13 Months (mon)	Participants were tested for anti-recombinant teriparatide and anti-synthetic teriparatide titers. Either none were detected (ND) or antibodies were determined to be present if the teriparatide specific antibody titers were at least 1:8 (titer 1:8).
DRAIZE Erythema Assessment at Baseline Through 13 Month Follow-up	13 Month follow-up	Severity of erythema was categorized based on a 5 point scale: 0=no erythema, 4=severe erythema (defined as beet red to eschar)
