Lead Sponsor:

Zelos Therapeutics

Conditions:

Hip Fracture

Eligibility:

All Genders

30+ years

Phase:

PHASE2

Brief Summary

The purpose of this research study is to test if an experimental drug called ZT-031 can help men over 30 years or post-menopausal women over 55 years of age with certain types of hip fracture to heal ...

Eligibility Criteria

Inclusion

  • Inclusion Criteria
  • Subjects are required to meet all of the following criteria for inclusion in the study:
  • Signed Institutional Review Board (IRB)/Research Ethics Board (REB)-approved informed consent form (ICF).
  • Sustained an unstable low energy intertrochanteric (Evans Type II or higher) hip fracture within 7 days prior to planned surgery date. Low energy is defined as a fracture that occurs spontaneously or from a fall from a stationary height of ≤ 1 meter (3 feet) or missing one to three steps.
  • Women ≥ 55 years of age and men ≥ 30 years of age of any race. If female, subjects must be post-menopausal for at least 5 years and weigh ≥ 110 lbs or 50 kg.
  • Subjects who are expected to undergo or have recently undergone (within two weeks) open or closed repair of the fracture requiring a CHS.
  • By history, the subject was at least household ambulatory prior to hip fracture.
  • Serum calcium level within the normal range when corrected for albumin. Corrected calcium (mg/dL) = Serum Ca (mg/dL) + 0.8 x (4.0 - albumin \[g/dL\])
  • Able and willing to comply with all protocol procedures.
  • Cognitive, visual, auditory and physical abilities adequate to undertake assessments.
  • Availability of a care partner to administer injections or demonstrated ability to self-administer injections. Subjects planning to self-administer study drug will need to show that they will be capable of accurately self-injecting study drug in rotating quadrants of the abdomen, in the opinion of the Investigator.
  • Clinically acceptable medical history and physical examination, according to the judgment of the Investigator.
  • Laboratory results within normal ranges or, if abnormal, considered by the Investigator as not clinically significant for the well-being of the subject or for the purpose of the study.
  • The following additional criteria are required for randomization and dosing with ZT-031 or placebo to occur:
  • The most recent value for 25-hydroxy Vitamin D (25OHD) must be at or above the lower limit of normal (LLN) for the laboratory reference range of the testing method used for determination of 25OHD. NOTE: Randomization should be delayed until it is known that 25OHD is ≥ LLN.
  • The most recent value for intact PTH must be ≤ ULN for the laboratory reference range.
  • Randomization and dosing must occur within 2 weeks post-op. Exclusion Criteria
  • Subjects who meet any of the following conditions are excluded from this clinical study:
  • Previous fracture(s) or bone or joint surgery in the currently fractured site
  • Intertrochanteric fracture with reverse obliquity
  • Pathologic fracture: A fracture occurring at a site of metabolic bone disease (other than osteoporosis) or a benign or malignant tumor
  • Presence of a concurrent disease known to affect bone metabolism other than post-menopausal osteoporosis, including but not limited to hyperparathyroidism, hyperthyroidism, osteogenesis imperfecta, abnormalities of serum calcium, Paget's disease, or osteomalacia
  • History of rheumatoid arthritis
  • Any significant neurologic disease including but not limited to any dementing illness or other neurodegenerative disease, cerebrovascular disease, epilepsy or undiagnosed syncope
  • Unstable or clinically significant cardiovascular disease resulting in:
  • Hemodynamic instability manifested as hypotension unresponsive to intravenous fluids
  • Uncontrolled hypertension requiring administration of parenteral therapy.
  • Renal disease, defined by:
  • Creatinine level of \>2.0 mg/dL
  • Urolithiasis or nephrolithiasis in the last 2 years
  • Hepatic disease or insufficiency, defined by liver function tests (ALT, AST or GGT) \> 3 times the ULN or bilirubin \> 34 mmol/L or 2.0 mg/dL
  • Currently receiving treatment for cancer
  • History of external beam radiation to the skeleton or a radiation therapy implant device
  • Presence of substance abuse, including alcohol, within 1 year of Screening
  • Current or previous use of any PTH compound, including ZT-031
  • Use of any investigational compound within 4 weeks of Screening, or within 5 half-lives of compound, whichever is longer
  • Use of any bone substitutes, osteobiologics or any fracture healing drug.
