Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 65 to 91 years
  • Women only
  • No healthy volunteers
  • Older adult

Who may be able to join

  • Subject is a postmenopausal female at least 1-year post menses and at least 65 years of age and less than 92 years of age.
  • Subject presents with a low-energy index fragility hip fracture in one hip and will undergo surgical repair of the fractured hip.
  • Subject has at least one of the following additional risk factors for a secondary hip fracture (as determined by subject or legally authorized representative (LAR) interview or medical record review):
  • Documented falls assessment indicating subject is at moderate or high risk of falls
  • Falls history (2 or more falls in the previous 12 months)
  • History of vertigo, dizziness, or postural hypotension
Show all 20Show fewer
  • Documented T-score < -2.5 at the hip
  • Taking more than 3 daily prescription medications
  • Visual impairment as confirmed by one of the following:
  • Subject reports difficulty seeing
  • Lack of depth perception or vision loss in one eye
  • Macular degeneration
  • Cataracts

About this study

Official title: Randomized Controlled Study of a Local Osteo-Enhancement Procedure (LOEP) to Prevent Secondary Hip Fractures in Osteoporotic Women Undergoing Treatment of Index Hip Fractures

A randomized controlled trial to evaluate AGN1 to prevent secondary hip fractures in osteoporotic women undergoing treatment of index hip fractures. Up to 2400 subjects will be randomized between a treatment group and a control group. Subjects will be followed for a minimum of 5 years after undergoing hip fracture repair surgery.

Read the detailed description

This is an event driven, randomized, controlled, prospective, single blinded (non-blinded in Canada), multi-national study.

This study is designed to demonstrate that the AGN1 LOEP treatment can reduce the incidence of secondary hip fractures in subjects presenting with an index hip fracture and undergoing hip fracture repair surgery. Subjects presenting with an index fragility hip fracture who will undergo hip fracture repair will be enrolled. Subjects will be randomized 1:1 into the following two study groups:

  1. Treated Group - receives standard of care to repair the index hip fracture and AGN1 LOEP treatment on the target unfractured contralateral hip
  2. Control Group - receives standard of care to repair the index hip fracture and no AGN1 LOEP treatment on the target unfractured contralateral hip

AGN1 LOEP is an elective procedure that will be performed immediately following hip fracture repair.

Subjects will be followed through scheduled visits conducted at 6 weeks, 6 months, and every 6 months thereafter for a minimum of 5 years.

Control groupNo interventionSubject receives standard of care to repair the index hip fracture and no AGN1 LOEP treatment on the target unfractured contralateral hip

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cumulative incidence of secondary fragility hip fractures

    Comparison of incidence of secondary fragility hip fractures in the target hip among the Treated Group vs. Control Group.

    Measured: Interim Analysis, approximately 30 Months

  2. Cumulative Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Comparison of incidence of AEs and SAEs among the Treated Group vs. Control Group.

    Measured: Interim Analysis, approximately 30 Months

Secondary outcomes (1)
  1. Areal bone mineral density (aBMD)

    Total hip areal bone mineral density in target hips of the Treated Group compared to the Control Group

    Measured: 12 months and 24 months

Questions about this trial

What is this clinical trial studying?

A study testing AGN1 LOEP treatment in people with Fragility Fracture and Hip Fractures, run by AgNovos Healthcare, LLC at 66 sites in 11 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 13 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 66 sites in Japan, Spain, Germany, United Kingdom, France and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Charles Raymond (240-753-6421, restore@agnovos.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative incidence of secondary fragility hip fractures (time frame: Interim Analysis, approximately 30 Months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2026.
