Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A 12-month study to measure the efficacy and safety of abaloparatide in men with osteoporosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective of this prospective controlled study is to evaluate the efficacy and the safety of abaloparatide 80 micrograms (mcg) per day administered subcutaneously (SC) compared to placebo in men with osteoporosis. Efficacy was primarily assessed by the change in bone mineral density (BMD) over 12 months.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Abaloparatide

Participants self-administered daily doses of abaloparatide 80 mcg SC using a single-participant, multiple-use, prefilled injection pen that delivers 30 doses. Participants received a new injection pen every 30 days.

Group Type EXPERIMENTAL

Abaloparatide

Intervention Type DRUG

Abaloparatide is a synthetic peptide that is a potent and selective activator of the parathyroid hormone 1 receptor signaling pathway.

Placebo

Participants self-administered daily doses of placebo SC using a single-participant, multiple-use, prefilled injection pen that delivers 30 doses. Participants received a new injection pen every 30 days.

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DRUG

Abaloparatide-matched placebo.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy ambulatory male from 40 to 85 years of age (inclusive) with primary osteoporosis or osteoporosis associated with hypogonadism.
* The participant has a BMD T-score based on female or male reference range (depending on date of enrollment) as assessed by the central imaging vendor of ≤ -2.5 at the lumbar spine (L1-L4) or hip (femoral neck or total hip) by dual energy X-ray absorptiometry (DXA) or ≤ -1.5 and with radiologic evidence of vertebral fracture or a documented history of low-trauma nonvertebral fracture sustained in the past 5 years. Men older than 65 years may be enrolled if they have a BMD T-score ≤ -2.0 even if they do not meet the fracture criteria.
* Normal medical history, physical examination, including vital signs, and body mass index.
* Hypogonadal participants whose doses of androgens have been stable for at least twelve months before randomization are eligible and may continue therapy during the study.
* Laboratory tests within the normal range including serum calcium (albumin-corrected), parathyroid hormone, serum phosphorus and alkaline phosphatase, and thyroid stimulating hormone values.

Exclusion Criteria

* Presence of abnormalities of the lumbar spine that would prohibit assessment of spinal BMD, defined as having at least 2 radiologically evaluable vertebrae within L1-L4.
* A BMD T-score of ≤-3.5 at the total hip, femoral neck, or lumbar spine based on female or male reference range (depending on date of enrollment).
* Unevaluable hip BMD or participants who have undergone bilateral hip replacement.
* Fragility fracture within the prior twelve months.
* History of severe vertebral fracture or \>2 moderate vertebral fractures.
* History of bone disorders (for example, Paget's disease) other than osteoporosis.
* participant with clinical signs of hypogonadism present at screening who plan to initiate testosterone replacement.
* History of prior external beam or implant radiation therapy involving the skeleton other than radioiodine.
* History of chronic or recurrent renal, hepatic, pulmonary, allergic, cardiovascular, gastrointestinal, endocrine, central nervous system, hematologic or metabolic diseases, or immunologic, emotional and/or psychiatric disturbances to a degree that would interfere with the interpretation of study data or compromise the safety of the participant.
* History of Cushing's disease, growth hormone deficiency or excess, hyperthyroidism, hypo- or hyperparathyroidism or malabsorptive syndromes within the past year.
