Safety and Tolerability Study of Multiple Doses of PF-06305591

This study has been completed.
Information provided by (Responsible Party):
Pfizer Identifier:
First received: January 23, 2013
Last updated: December 2, 2013
Last verified: December 2013
Safety, tolerability and PK of repeated doses of PF-06305591 will be evaluated in young healthy volunteers toghether with food effect on relative bioavailability of solid formulation after single dose.

Condition Intervention Phase
Drug: PF-06305591
Drug: Placebo
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Basic Science
Official Title: A Double Blind (3rd Party Open) Randomized, Dose Escalation Study to Investigate the Safety, Tolerability, Pharmacokinetics of Repeat Doses PF-06305591 Combined With a Cross-over Relative Bioavailability and Food Effect Evaluation After Single Dose of PF-06305591 in Healthy Young Subjects

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: 14 days ]
    Counts of participants who had treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Relatedness to [study drug] was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.

  • Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 14 days ]
  • Area under the Concentration-Time Curve (AUC) [ Time Frame: 14 days ]
    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption.

  • Area Under the Curve from Time Zero to end of dosing interval (AUCtau) [ Time Frame: 14 days ]
    AUC is a measure of the serum concentration of the drug over time interval. It is used to characterize drug absorption.

Ages Eligible for Study:   21 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Healthy male or female subjects of non childbearing potential, between the ages of 21 and 55 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

Exclusion Criteria:

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
  • Any condition possibly affecting drug absorption (eg, gastrectomy).
