Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase I Study To Evaluate The Safety, Tolerability, Immunogenicity, Pharmacokinetics And Pharmacodynamics Of Escalating Doses Of RN564 In Women With Osteopenia And In Healthy Men

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Incidence of dose limiting or intolerable treatment related adverse events (AEs) [ Time Frame: Duration of the study ]
  • Incidence, severity and causal relationship of treatment emergent AEs (TEAEs) [ Time Frame: Duration of the study ]
  • Incidence of abnormal laboratory findings (clinical chemistry, hematology and urinalysis) [ Time Frame: Duration of the study ]
  • Changes from baseline in safety laboratory assessments. [ Time Frame: Duration of the study ]
  • Abnormal and clinically relevant changes in vital signs, BP, and ECG parameters. [ Time Frame: Duration of the study ]

Secondary Outcome Measures:
  • The PK parameter estimates will include but not be limited to: AUC(0-t[last]), Tmax, Cmax, terminal elimination half-life (t1/2), Clearance (CL), apparent volume of distribution (Vz), volume of distribution at steady state (Vss), and AUC of RN564. [ Time Frame: Days 1, 2, 3, 4, 5, 8, 15, 22, 29, 36, 43, 57 and 85 ]
  • Percentage change from baseline (average of Day -1 and Day 1 prior to infusion of RN564) in total DKK-1 concentrations over time inclusive of 85 days. [ Time Frame: Days -1, 1, 2, 3, 4, 5, 8, 15, 22, 29, 36, 43, 57 and 85 ]
  • Percentage change from baseline (average of Day -1 and Day 1 prior to infusion of RN564) in serum PINP, NTX, CTX, bone specific alkaline phosphatase and osteocalcin over time inclusive of 85 days. [ Time Frame: Days -1, 1, 2, 3, 4, 5, 8, 15, 22, 29, 36, 43, 57 and 85 ]
  • Percentage change from baseline in lumbar spine, total hip, femoral neck and distal radius BMD at Day 85. [ Time Frame: Day -1 and 85 ]
  • PK/PD model describing the relationship between RN564 PK parameter estimates/concentrations and changes in pharmacodynamic endpoints. [ Time Frame: Duration of the study ]

Enrollment: 68
Study Start Date: April 2011
Study Completion Date: May 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1 Biological: RN564
Intravenous, single dose with experimental dose


Ages Eligible for Study:   55 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Diagnosis of osteopenia for women (BMD T-scores between -1.0 and - 2.5 SD at the lumbar spine, the femoral neck or total hip)
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >45 kg (99 lbs).
  • Have at least 3 vertebral bodies in the L1-L4 region and one femoral neck site that are accessible by DXA.

Exclusion Criteria:

  • Evidence or history of any underlying condition, other than primary osteopenia, that affect bone metabolism (eg, hyperparathyroidism, hypoparathyroidism).
  • Subjects with pre-existing periodontal/dental disease or those who have undergone invasive dental procedures (eg, tooth extraction, oral surgery) within 60 days prior to Day -1.
  • If QTcF exceeds 455 msec, the ECG should be repeated two more times and the average of the three QTcF values should be used to determine the subject's eligibility.
