A Clinical Study Evaluating The Safety And Tolerability Of PF-04427429 In Healthy Adult Volunteers. The Pharmacokinetics And Pharmacodynamics Of PF-04427429 Will Also Be Investigated

This study has been completed.
Information provided by (Responsible Party):
Pfizer Identifier:
First received: July 16, 2010
Last updated: February 21, 2012
Last verified: February 2012
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of PF-04472429 administered intravenously to healthy adult volunteers.

Condition Intervention Phase
Healthy Biological: PF-04427429 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomised, Placebo Controlled, Double-Blind, Third Party Open, Parallel Group Study To Evaluate the Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Repeat Doses 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: up to 129 days ]
  • 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: up to 129 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: up to 129 days ]

Secondary Outcome Measures:
  • pharmacodynamics (free and total CGRP plasma concentration) will be measured, the PK-PD relationship between plasma PF-0447429 concentrations and free/total CGRP concentrations will be characterised [ Time Frame: up to 129 days ]

Enrollment: 21
Study Start Date: August 2010

Exclusion Criteria:

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