Phase I Study Of The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Multiple Intravenously Administered Doses Of PF-04236921 In Patients With Rheumatoid Arthritis

12. marts 2018 opdateret af: Pfizer

Phase 1, Randomized, Patient And Investigator-blind, Placebo-controlled Study To Investigate The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Multiple Intravenously Administered Doses Of Pf-04236921 In Patients With Rheumatoid Arthritis Receiving Methotrexate

This study will evaluate the safety and tolerability of PF-04236921 administered monthly as three intravenous infusions. Each group of patients will be assigned to a dose level; Safety and tolerability of a low dose level will be required before proceeding to successively higher dose levels. Blood tests will be performed to measure the amount of drug and changes in measures of inflammation.

Tidsramme
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Tidsramme: Baseline up to 28 days after last dose of study medication or until serum PF-04236921 concentrations below the LLOQ (up to Day 624)
An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication and up to 28 days after last dose or until serum PF-04236921 concentrations were below the LLOQ that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.
