Phase 2 Study of BA058 (Abaloparatide) Transdermal Delivery in Postmenopausal Women With Osteoporosis

Registration Number
NCT01674621
Lead Sponsor
Radius Health, Inc.
Brief Summary

To determine the clinical safety and efficacy of abaloparatide transdermal in otherwise healthy postmenopausal women with osteoporosis as assessed by changes in bone mineral density (BMD) and serum markers of bone metabolism when compared to transdermal placebo and abaloparatide injection for 6 months of treatment.

Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Bone Mineral Density (BMD) of Lumbar Spine at 6 MonthsBaseline, 6 Months

Percent change in BMD as specified by dual energy x-ray absorptiometry (DXA) scans of the lumbar spine.

Secondary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Serum Procollagen Type I C Propeptide (PICP) at 6 MonthsBaseline, 6 Months
Percent Change From Baseline in BMD of Total Hip at 6 MonthsBaseline, 6 Months

Percent change in BMD as specified by DXA scans of the total hip.

Percent Change From Baseline in Serum Osteocalcin at 6 MonthsBaseline, 6 Months
Percent Change From Baseline in Serum Carboxy-terminal Cross-linking Telopeptide of Type I Collagen (CTXI) at 6 MonthsBaseline, 6 Months
Number of Participants With Abnormal Physical Examinations at Screening and End of Treatment (6 Months)Baseline up to 6 Months

A full physical examination included, at a minimum: general appearance, skin, head/ears/eyes/nose/throat, lungs/chest, breasts, heart, abdomen, lymph nodes, musculoskeletal, extremities, and neurologic. Physical examination results that were considered abnormal were determined by the Investigator. A summary of other non-serious adverse events (AEs) and all serious AEs (SAEs), regardless of causality is located in Reported AE section.

Percent Change From Baseline in BMD of Forearm at 6 MonthsBaseline, 6 Months

Percent change in BMD as specified by DXA scans of the forearm.

Percent Change From Baseline in Serum Bone-Specific Alkaline Phosphatase (BSAP) at 6 MonthsBaseline, 6 Months
Number of Participants With a Clinically Meaningful Abnormal Electrocardiogram (ECG) Test ResultBaseline up to 7 Months

The following ECG parameters were recorded: rhythm, heart rate, PR interval, QRS duration and QT/QTc. ECG results that were considered clinically meaningful were to be determined by the Investigator. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.

Number of Participants With an Abnormal Clinical Coagulation Laboratory Parameter With an ECOG Score of Grade 3 or Grade 4Baseline up to 6 Months

Coagulation laboratory parameters that were evaluated via ECOG Grade 3 and Grade 4 criteria (presented in parentheses) included: prothrombin time (quick) (Grade 3: 1.51%-2.00%\*normal, Grade 4: \>2.00%\*normal), partial thromboplastin time (Grade 3: 2.34-3.00 seconds \[sec\], Grade 4: \>3.00 secs\*normal). A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) That Occurred During the Study That Were Associated With Vital Sign ChangesBaseline up to 7 Months

Vital sign parameters included respiration rate (breaths/minute), body temperature (°C), systolic blood pressure (SBP) and diastolic blood pressure (DBP) (mmHg), and heart rate (bpm). Number of participants for each TEAE is presented. The same participant may be included in more than one TEAE category. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.
