Intervention / Behandlung
Experimental: Hydrocodone ER
Participants were titrated (or re-titrated for roll-over participants) at escalating dosages of extended-release hydrocodone tablets at dosages of 15, 30, 45, 60, or 90 mg orally every 12 hours until deemed successful for managing their pain during the open-label titration period. Once a successful dose was identified, participants entered the 52 week open-label treatment period in which hydrocodone ER was administered at the successful dose (15, 30, 45, 60, or 90 mg) every 12 hours.
Arzneimittel: Hydrocodone ER
Hydrocodone bitartrate extended-release tablets were administered at doses of 15, 30, 45, 60, and 90 mg orally every 12 hours. During the open-label titration period, doses were adjusted until a stable pain control was achieved. In general, the dose of hydrocodone extended release tablets could be adjusted for efficacy or tolerability, as necessary, at any time during the open-label treatment period; however, participants were required to visit the study center before increasing the dose of study drug.

Shifts in Electrocardiogram (ECG) Findings From Baseline to Overall Study by Participant Status
Zeitfenster: Baseline for new participants was between Day -7 and -14 (the study 3080 screening visit); baseline for rollover participants was the last ECG in study 3079. During study ECGs were performed on weeks 24 and 52 of the open-label treatment period

A 12-lead ECG was conducted at screening, week 24, and week 52 or at the last postbaseline observation. For rollover participants, the ECG performed at the final visit of study 3079 served as the 1st ECG in study 3080. A qualified physician was responsible for interpreting the ECG. Any ECG finding that was judged by the investigator as a clinically meaningful change (worsening) compared with baseline was considered an adverse event.

For overall results, the worst postbaseline finding for the participant was summarized.

Results below are formatted as Baseline ECG result - Overall ECG result.
Baseline for new participants was between Day -7 and -14 (the study 3080 screening visit); baseline for rollover participants was the last ECG in study 3079. During study ECGs were performed on weeks 24 and 52 of the open-label treatment period
Participants With Clinically Significant (CS) Hearing Changes From Baseline in Pure Tone Audiometry Test Results by Patient Status
Zeitfenster: Baseline for new participants was between Day -7 and -14 (study 3080 screening visit); baseline for rollover participants was the baseline test in study 3079. During study covers both open-label titration and 52-week treatment periods
Pure tone audiometry was performed by trained personnel. During the test, the patient wore headphones and was seated in a quiet room; trained personnel manipulated the audiometry equipment to test the patient's hearing. For serial audiograms, the criteria for a clinically significant (CS) hearing change were based on the guidance from the American Speech-Language Hearing Association (ASHA) 1994 (Konrad-Martin et al 2005). These criteria included the following: greater than 20 decibels (dB) pure tone threshold shift at 1 frequency; greater than 10 dB shift at 2 consecutive test frequencies; or threshold response shifting to "no response" at 3 consecutive test frequencies.
Baseline for new participants was between Day -7 and -14 (study 3080 screening visit); baseline for rollover participants was the baseline test in study 3079. During study covers both open-label titration and 52-week treatment periods

Participant Global Assessment (PGA) of the Method of Pain Control by Participant Status
Zeitfenster: Baseline for new participants was Day 1, i.e. the first day of open-label titration. Baseline for rollover participants was the baseline in study 3079. Week 4 (end of titration, start of open-label treatment), Week 52, last visit up to Week 52
The PGA of the method of pain control consisted of a asking patients a single question to assess their method of pain control during the previous 24 hours as either poor, fair, good, or excellent (Rothman et al 2009).
Baseline for new participants was Day 1, i.e. the first day of open-label titration. Baseline for rollover participants was the baseline in study 3079. Week 4 (end of titration, start of open-label treatment), Week 52, last visit up to Week 52
Participants by Risk Category for Aberrant Drug Misuse Based on the Total Score in the Screener and Opioid Assessment for Patients With Pain - Revised (SOAPP-R)
Zeitfenster: End of Open-label Titration Period. Weeks 4 and 24 of the Open-label Treatment Period

SOAPP-R is a clinician-rated scale used to assess each patient's risk of developing aberrant drug use behaviors while on long term opioid therapy. SOAPP-R consists of 24 questions that address 8 concepts: substance abuse history, medication related behaviors, antisocial behaviors/history, psychosocial problems, psychiatric history, physician patient relationship factors, emotional attachment to pain medications, and personal care and lifestyle issues (Butler et al 2008). Each question is answered using a 5 point Likert-like scale, with 0=never, 1=seldom, 2=sometimes, 3=often, and 4=very often for a total range of 0-96. The higher the overall score, the greater the probability the patient is at risk for displaying aberrant behaviors consistent with drug use.

An overall score of 18 or higher is considered positive for predicting aberrant drug related behavior, therefore the reported risk categories are

  • <18 and
  • <=18. Results indicate timeframe followed by risk cat
End of Open-label Titration Period. Weeks 4 and 24 of the Open-label Treatment Period
Addiction Behavior Checklist (ABC) Total Scores During Both the Open-Label Titration and Open-Label Treatment Periods by Participant Status
Zeitfenster: Baseline for new participants was Day 1 of open-label titration; rollover participants baseline was in study 3079. End of Open-label Titration: Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36 40, 44, 48, 52 and last visit up to week 52
The ABC was a clinician rated scale that consisted of a brief (21 item) questionnaire designed to track behaviors characteristic of addiction related to prescription opioid medications in chronic pain populations. Items were focused on observable behaviors noted both during and between clinic visits. Each affirmative response was counted as 1 point, and points were added to calculate the total score. All but 1 of the 21 items (the provider's impression) was used in calculating the total score, consequently resulting in scores ranging from 0 to 20 (0=no addiction-related behaviors seen and higher scores indicating an increasing number of addition-related behaviors seen). Participants with a total score of 3 or greater were classified as exhibiting inappropriate opioid use during the study.
Baseline for new participants was Day 1 of open-label titration; rollover participants baseline was in study 3079. End of Open-label Titration: Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36 40, 44, 48, 52 and last visit up to week 52
Current Opioid Misuse Measure (COMM) Scores During Both the Open-Label Titration and Open-Label Treatment Periods by Participant Status
Zeitfenster: Baseline for new participants was Day 1 of open-label titration; rollover participants baseline was in study 3079. End of Open-label Titration Period. Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36 40, 44, 48, 52 and last visit up to week 52
The COMM was a clinician-rated scale developed as a brief self-report measure of current aberrant drug-related behavior for patients with chronic pain who were already on long-term opioid therapy. A total score was calculated as the sum of the 17 questions. The total score ranged from 0 to 68. A score of 0 indicates no aberrant drug-related behaviors were seen. Patients with a total score of 9 or greater were classified as exhibiting aberrant drug-related behavior.
Baseline for new participants was Day 1 of open-label titration; rollover participants baseline was in study 3079. End of Open-label Titration Period. Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36 40, 44, 48, 52 and last visit up to week 52
