Study in Patients With Osteoporosis and Fragility Fractures to Estimate the Extent and Impact of Delayed Administration of Anti-fracture Therapy (OPGAP01)

April 1, 2026 updated by: Maurizio Mazzantini, Azienda Ospedaliero, Universitaria Pisana

Retrospective Multicenter Study in Patients With Osteoporosis and Fragility Fractures to Estimate the Extent and Impact of Delayed Administration of Anti-fracture Therapy

Osteoporosis (OP) and fragility fractures are a significant problem that leads to morbidity, mortality, and high costs for the National Health System. The treatment of fragility fractures includes numerous anti-resorptive and anabolic drugs, and its goal is the secondary prevention of new fractures. It is well known that the risk of a new fracture following a fracture event is highest in the months immediately following the first fracture. However, recent data clearly show a dramatic global delay in the administration of anti-osteoporotic therapy following a fragility fracture. It has been estimated that in Italy, 71% of patients with fragility fractures eligible for anti-fracture treatment did not receive timely treatment (a problem defined as a "treatment gap"), and that in 2034, the incidence of new fragility fractures will increase compared to 2019 [1]. However, there is a lack of real-life Italian data on the extent of the treatment gap in osteoporotic patients with fragility fractures and its impact in terms of the incidence of subsequent fragility fractures: this study therefore aims to fill this gap by collecting data from a large population of patients attending several centers throughout the country.

Detailed Description

Italian real-life study in patients with osteoporosis and fragility fractures to assess the extent and impact of delays in the administration of anti-fracture therapy.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Consecutive adults affected by osteoporosis and fragility fractures attending regular outpatient visits at participating centers. After submitting written informed consent for enrollment in the study, the information necessary for the study will be collected. The information that will be collected is that contained in the medical records, acquired in normal clinical practice for the management of this type of patient.

Description

Inclusion Criteria:

  • adult patients of both sexes;
  • patients with osteoporosis and/or previous fragility fractures (fragility fractures are defined as those that occur spontaneously, i.e., not resulting from trauma, even of low intensity, or those caused by a fall from standing height.
  • willingness to sign the consent form

Exclusion Criteria:

  • patients under the age of 18
  • no previous fragility fractures - failure to sign the consent form Exit criteria

Design Details

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
Objective and primary endpoint
Time Frame: From enrollment to the end of data records 1 year
the number of months elapsed between the first fragility (osteoporotic) fracture and the initiation of anti-osteoporotic therapy.
From enrollment to the end of data records 1 year

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
Objective and secondary endpoint
Time Frame: From enrollment to the end of data records 1 year
the incidence of new fragility (osteoporotic) fractures based on the time elapsed between the first fragility fracture and the initiation of anti-osteoporotic therapy.
From enrollment to the end of data records 1 year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
