January 13, 2025 updated by: Prof.Dr.Aree Tanavalee, M.D., King Chulalongkorn Memorial Hospital

A Phase III, Randomized, Double Blind, Placebo Controlled Study to Evaluate the Effect of Teriparatide on Bone Union in Unstable Intertrochanteric Fracture Patients Treated With Proximal Femoral Nail Antirotation (PFNA)

Phase III, prospective, randomized, parallel, double blind, placebo-controlled study to determine whether Teriparatide can accelerate bone healing in unstable intertrochanteric fracture patients treated with Proximal Femoral Nail Antirotation (PFNA) assessed by radiographic and clinical outcomes.

Study Overview

Status

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

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

Patients will undergo screening assessment to determine the eligibility for study participation and will be randomized in 1:1 ratio to receive Teriparatide 20 μg or placebo subcutaneous once daily for 12 weeks.

All patients will receive supplements of 1000 mg/day of elemental calcium and 20,000 IU/week of vitamin D2.

Patients will be scheduled to clinic visit for radiographic and clinical assessment at 2, 6,12 and 24 weeks postoperatively. Each participant will be in the study for 6 months in total.

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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Concurrent treatment with oral bisphosphonates, selective estrogen receptor modulator (SERMs), calcitonin, estrogen (oral, transdermal, or injection), progestin, estrogen analog, estrogen agonist, estrogen antagonist or tibolone, and active vitamin D3 analogs. (Previous treatment is allowed but must be discontinued at screening)
  12. Previous treatment with strontium ranelate for any duration, intravenous bisphophonates within 12 months prior to the screening date, and/or denosumab within 6 months prior to the screening.
  13. Previous treatment with teriparatide, PTH or other PTH analogs, or prior participation in any other clinical trial studying teriparatide, PTH or other PTH analogs

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to healing assessed by radiographic evidence
Time Frame: from randomization, assessed up to 24 months
Fracture is judged to be healed radiographically if bridging callus was evident on 3 of 4 cortices as seen on two views (cortical bridging of three cortices)
from randomization, assessed up to 24 months

Secondary Outcome Measures

Secondary Outcome Measures

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.
Outcome Measure
Measure Description
Time Frame
Clinical evidence of healing assessed by Harris Hip Score as one of functional outcomes
Time Frame: from randomization, assessed up to 24 months
Harris Hip Score (90-100: Excellent, 80-89: Good, 70-79: Fair, <70 poor)
from randomization, assessed up to 24 months
Clinical evidence of healing assessed by weight bearing ability as one of functional outcomes
Time Frame: from randomization, assessed up to 24 months
Weight bearing ability (Non weight bearing, Partial weight bearing, Full weight bearing)
