Brief Summary
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.

Interim Analysis, approximately 30 Months
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.
Interim Analysis, approximately 30 Months
Secondary Outcomes (2)
Areal bone mineral density (aBMD)
12 months and 24 months
Trabecular Bone Score (TBS)
12 months and 24 months
Study Arms (2)
Treated group
EXPERIMENTALSubject receives standard of care to repair the index hip fracture and AGN1 LOEP treatment on the target unfractured contralateral hip
Control group
NO INTERVENTIONSubject receives standard of care to repair the index hip fracture and no AGN1 LOEP treatment on the target unfractured contralateral hip
Interventions
the implantation site is injected with the AGN1 implant material
Eligibility Criteria
You may qualify if:
- Subject is a postmenopausal female at least 1-year post menses and at least 65 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
- 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
- Prior non-hip fragility fracture
- Cognitive frailty as assessed by SPMSQ (mild or moderate cognitive impairment) or delirium
- +5 more criteria
You may not qualify if:
- Subject hospital admission is \> 24 hours from the time of the index hip fracture.
- Subject was dependent on the use of a wheelchair or was bedridden prior to the index hip fracture.
- Subject is currently enrolled in another clinical study.
- Subject has a history of hip surgery or previous hip fracture on the target unfractured hip contralateral to the index hip fracture.
- Subject has one or more new fractures in addition to the index hip fracture at admission that, in the opinion of the investigator, would further compromise patient mobility, rehabilitation, and/or recovery or subject has three or more new fractures in addition to the index hip fracture.
- Subject has an infection at the LOEP intended treatment site or has non-intact skin or acute traumatic injuries with open wounds close to the area of intended LOEP treatment.
- Subject has a progressive increase in undiagnosed pain in the target hip contralateral to the index fractured hip over the previous 3 months that in the opinion of the Investigator may suggest underlying bone or joint pathology on the unfractured side.
- Subject has radiological evidence of gross bony or joint pathology of the hip, including signs predictive of atypical femoral fractures (e.g. cortical beaking), or has been diagnosed and/or treated for atypical femoral fractures.
- Subject is at ASA Class IV, V, or VI.
- Subject has a history of metabolic bone disease other than osteoporosis (e.g., Paget's disease, renal osteodystrophy, or osteomalacia).
- Subject has a history of Pott's disease.
- Subject has a history of any invasive malignancy (except nonmelanoma skin cancer), unless treated with curative intent and with no clinical signs or symptoms of the malignancy for 5 years.
- Subject has chronic cardiac insufficiency or severe cardiovascular disease as assessed by a subject or LAR interview to be NYHA Class III or IV or has an implanted pacemaker.
- Subject has a history of cardiovascular events (e.g. stroke, transient ischemic attack, myocardial infarction, unstable angina, pulmonary embolus, deep vein thrombosis, ventricular tachycardia, or atrial fibrillation) in the last 3 months.
- Subject is on oral or parenteral immuno-suppressive drugs.
