Study Details

Study Description

Brief Summary

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.

Outcome Measures

Primary Outcome Measures

  1. Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [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.

  2. Number of Participants With Positive Anti-drug Antibodies Response [Day 1, 28, 56, 84, 174, 354, End of Study (Day 624)]

  3. Maximum Observed Serum Concentration (Cmax): Day 1 [Day 1: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose]

  4. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 1 [Day 1: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose]

  5. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 1 [Day 1: Pre-dose (0 hour), 15 minutes, 168 hours post-dose]

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

  6. Maximum Observed Serum Concentration (Cmax): Day 28 [Day 28: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose]

  7. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 28 [Day 28: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose]

  8. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 28 [Day 28: Pre-dose (0 hour), 15 minutes, 168 hours post-dose]

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

  9. Maximum Observed Serum Concentration (Cmax): Day 56 [Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose]

  10. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 56 [Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose]

  11. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 56 [Day 56: Pre-dose (0 hour), 15 minutes, 168 hours post-dose]

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

  12. Serum Decay Half-Life (t1/2): Day 56 [Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose]

    Serum decay half-life is the time measured for the serum concentration to decrease by one half.

Other Outcome Measures

  1. Change From Baseline in C-Reactive Protein (CRP) Concentrations at Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624 and Early Discontinuation [Baseline, Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624, Early Discontinuation]

    The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultra sensitive assay. A decrease in the level of CRP indicates reduction in inflammation.

  2. Change From Baseline in Log CRP Concentrations at Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624 [Baseline, Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624]

    The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

  3. Change From Baseline in Absolute Neutrophil Counts at Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624 and Early Discontinuation [Baseline, Day 7, 14, 28, 35, 42, 56, 63, 70, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624, Early Discontinuation]

  4. Change From Baseline in Free Interleukin-6 (IL-6) Concentrations at Day 28, 56, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579 and 624 [Baseline, Day 28, 56, 84, 129, 174, 219, 264, 309, 354, 399, 444, 489, 534, 579, 624]

    Serum samples were analyzed for IL-6 concentrations using a validated analytical colorimetric Enzyme-Linked Immunosorbent Assay (ELISA) method.

Outcome Measures

1. Primary Outcome
Title Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Description 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.

Description The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

Data for this outcome measure was not assessed since this measure was analyzed as per sponsor discretion as the change from baseline in CRP in this study was well demonstrated with the raw CRP data. Therefore, log transformation of CRP was not performed.
