The Treatment of Osteoporosis Using a Combination of Teriparatide (Forteo) and Denosumab

August 30, 2017 updated by: Felicia Cosman, M.D., Health Research, Inc.
This is a three-year study to evaluate the effect of sequential therapy of Forteo (teriparatide) and denosumab on bone density at the spine, hip, leg and forearm.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In order to maximize the early anabolic effect with teriparatide (TPTD), and to avoid the development of tachyphylaxis to the continued daily administration of TPTD beyond 6 months, cyclic therapy might be optimal. Since Denosumab (Prolia) is a potent antiresorptive agent with a rapid off-effect, it might be the optimal agent to help maximize bone gains with cyclic TPTD/antiresorptive therapy. Our primary hypothesis is that the increment in bone density of the spine by DXA will be greater in women randomized to receive the cyclic sequential regimen (three separate 6 month cycles of daily subcutaneous TPTD, each followed by one subcutaneous injection of Denosumab) compared with daily sequential therapy (18 months of daily subcutaneous TPTD followed by Denosumab therapy for 18 months).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Description

Inclusion Criteria:Subjects should be postmenopausal >age 45, and of any racial origin. They must not be on any osteoporosis medication. They should be willing to participate for the duration of the study and have no physical or psychological illness that would prohibit them from participating. Pregnant women, protected individuals (institutionalized), and those unable to give informed consent will not be recruited. Exclusion criteria are detailed below.

Subjects who meet initial pre-screening criteria will present for an on site screening visit and have a full medical history, brief physical exam, BMD and lab evaluation to confirm eligibility. Osteoporosis will be defined by DXA BMD T-Score < -2.5 at lumbar spine (at least 2 evaluable vertebrae between L1 and L4), or total hip or femoral neck. In addition, women with confirmed vertebral deformity on radiograph or lateral DXA image, or prior osteoporosis-related fracture at age >45 along with a DXA BMD T-Score < -1.5 at one or more skeletal sites will be eligible to participate.

Exclusion Criteria:

  • The use of drugs known to affect skeletal or calcium homeostasis.
  • Multiple vertebral fractures or severe lumbar degenerative changes with fewer than 2 evaluable lumbar vertebrae

  • Current use of anti-resorptive medicines

    • Use of Hormone/Estrogen Therapy, raloxifene or calcitonin within the past 3 months
    • Use of oral bisphosphonate for more than 4 months within the past 2 years or more than 5 years total cumulative bisphosphonate use in the past 10 years
    • Use of intravenous ibandronate within the past 18 months
    • Use of intravenous zoledronic acid within the past 4 years
    • A history of a symptomatic renal stone within the past 3 years or history of multiple symptomatic renal stones
    • Skeletal Disorders other than osteoporosis including: Hypercalcemia, hyperparathyroidism, Paget's Disease or osteomalacia
    • Untreated or uncontrolled thyroid disease
    • Elevated Bone Specific Alkaline Phosphatase level
    • History of external or internal radiation therapy
    • Renal insufficiency with estimated GFR below 30 ml/min
    • Liver function tests (ALT/AST) more than 1.5 times the upper limit of normal
    • Clinically significant hyperuricemia or active gout
    • Any contraindications to receipt of Teriparatide or Denosumab (including hypocalcemia)
    • History of an atypical fracture of the femoral shaft

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
