Usability of Zubsolv Sublingual Tablets 5.7/1.4 to Suboxone Sublingual Film 8/2 In Buprenorphine/Naloxone Treated Opioid Dependent Population

The primary objective of this study is to compare overall patient preference for either Suboxone® sublingual film 8/2 or Zubsolv® sublingual tablets 5.7/1.4. Suboxone sublingual film 8/2 contains 8mg buprenorphine and 2mg naloxone. Zubsolv sublingual tablets contain 5.7 mg buprenorphine and 1.4 mg naloxone. Both interventions act as a substitute for opiate drugs like heroin, morphine or oxycodone and help withdrawal from opiate drugs over a period of time.

Other names: buprenorphine, naloxone

Primary outcomes

  1. Overall Intervention Preference As Assessed by Participants

    Time frame: Day 1

    At the conclusion of Study Day 1, participants completed a study exit product comparison questionnaire. This outcome summarizes the percentage of participant answers to the question: When thinking about the two medications you evaluated over the last two days, which medication type did you prefer?

Secondary outcomes

  1. Participant Preference With Regard to Overall Taste of Interventions

    Time frame: Day 1

    At the conclusion of Study Day 1, participants completed a study exit product comparison questionnaire. This outcome summarizes the percentage of participant answers to the question: Which one did you prefer in regards to overall taste?

  2. Participant Assessments With Regard to Ease of Dissolution of Interventions

    Time frame: Day 1

    At the conclusion of Study Day 1, participants completed a study exit product comparison questionnaire. This outcome summarizes the percentage of participant answers to the question: Which one did you think dissolve easier in your mouth?

  3. Percentage of Participant Favorable and Unfavorable Response to the Question: How Easy or Difficult Was it to Open the Package?

    Time frame: Days 0-1

    Responses were captured on a 5-point scale with the 5 representing the most favorable response, 3 representing a neutral response and 1 representing a negative response. 'Favorable' responses include assessments 5 and 4, while 'Unfavorable' responses include assessments 3, 2 and 1.

  4. Percentage of Participant Favorable and Unfavorable Response to the Question: How Easy or Difficult Were the Package Instructions to Follow?

  13. Dissolution Time of Intervention as Recorded by a Trained Observer

    Time frame: Days 0-1

    The subject was observed and times documented for time of administration and time dissolution (recorded in minutes and seconds) was completed by designated qualified study personnel at the site.

  14. Change From Baseline in Subject Opiate Withdrawal Scale (SOWS)

    Time frame: Day 0 prior to dosing, end of Day 0 (post dose), end of Day 1 (post dose)

    Participants completed the Subject Opiate Withdrawal Scale (SOWS) at baseline, and the end of each day of treatment.

    SOWS is a validated scale when used as defined. The research site did not use SOWS as defined. The sponsor made the decision to not report this data since it was not captured in a validated format.
