  Purpose
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of PF-04427429 administered intravenously to healthy adult volunteers.

Condition Intervention Phase
Healthy Volunteers Drug: PF-04427429 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: A Randomized, Placebo Controlled, Double-Blind, Third Party Open, Parallel Group, First In Human Study To Evaluate The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of PF-04427429 Administered Intravenously To Healthy Adult Volunteers

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Safety (incidence/severity of adverse events and clinical laboratory abnormalities, mean change from baseline/placebo in vital signs/body temperature, mean change from baseline in 12 lead electrocardiogram parameters compared to baseline/ placebo) [ Time Frame: anticipated time is up to 84 days post dose ]
  • Safety continued (categorical summary of QTcF compared to baseline between dose groups and placebo, concentration QTcF relationship, ADA responses, IV injection site reactions) [ Time Frame: anticipated time is up to 84 days post dose to 84 days ]
  • Pharmacokinetics (Free plasma concentrations of PF-04427429 will be measured by a validated assay and non-compartmental PK parameters will be determined for each dose) [ Time Frame: anticipated time is up to 84 days post dose days ]

Secondary Outcome Measures:
  • Pharmacodynamics (free and total CGRP plasma concentrations will be measured, the PK-PD relationship between plasma PF-04427429 concentrations and free/total CGRP concentrations will be characterized) [ Time Frame: anticipated time is up to 84 days ]

Estimated Enrollment: 24
Study Start Date: December 2009
Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)

Criteria

Inclusion Criteria:

  • Healthy male subjects between the ages of 18 and 50 years, inclusive (Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead ECG and clinical laboratory tests).
  • Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight of between 50 kg and 100 kg inclusive.
  • Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial.
  • Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
  • Willing and able to comply with the requirement for using the recommended highly effective contraceptive methods throughout the study.

Exclusion Criteria:

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, genitourinary, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, symptomatic, seasonal allergies at time of dosing).
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
  • History of febrile illness within 5 days prior to the first dose.
  • A positive urine drug screen
