Clinical Trial Summary

This study will examine how the use of Xtampza ER, an opioid analgesic packaged in openable microsphere-containing capsules, affects swallowing satisfaction, pain, and physical and mental health outcomes in chronic pain patients.

Description:

An important step in the evolution of pain care is more personalized medicine. One aspect of personalized medicine emphasizes that patients often have additional requirements for prescription medicines beyond just pain relief, including ease in taking medications and overall satisfaction with their care. Surveys indicate that 20% of adult patients either with or without pain have difficulty swallowing their medications, and up to 10% refuse to take a specific therapy because they cannot swallow the pills [1-3]. It is likely that this issue compromises the quantity, quality, and satisfaction with pain relief from oral opioids.

Xtampza ER is an opioid analgesic consisting of a microsphere-containing capsule that can be opened so the microspheres can be added to soft food. This drug is designed to overcome capsule-swallowing issues and therefore may be an important tool for personalized pain medicine care. This study will investigate the pharmaceutic delivery properties of Xtampza to determine whether it is an improved alternative to the pill-swallowing problems that are common with opioid drugs.

Recruitment information / eligibility

• Status: Terminated
• Enrollment: 11
• Est. completion date: October 31, 2019
• Est. primary completion date: July 31, 2019
• Accepts healthy volunteers: No
• Gender: All
• Age group: 21 Years to 65 Years

Eligibility

Inclusion Criteria:

1. Adult subjects must have noncancer chronic pain for at least six months on a daily basis,

2. Be prescribed opioids on a daily basis

3. Have an upper dose limit of daily opioids of 200 mg of morphine equivalents. This is because at doses greater than 200 mg daily, in the investigator's experience it is much more difficult to convert completely to another opioid compound within a week. Fentanyl and methadone users will not be specifically excluded unless their dosages fall outside this range.

4. Ages 21-70

5. Reported difficulty swallowing their opioid medication on the screening form at a level determined significant by the PI.

6. Having a mobile phone. A smart phone is not required to respond to the text messages.

7. Having Internet access to be able to respond to the emailed weekly surveys.

8. If sexually active and able to become pregnant, must agree to use an acceptable method of birth control (hormonal methods, barrier methods with spermicide, intrauterine device (IUD) or abstinence).

9. Only Pain Medicine Clinic patients may participate in this study

Exclusion Criteria:

1. Inability to understand the surveys and complete them.

2. Pregnancy

3. High risk for opioid addiction and/or abuse behaviors

4. Any condition, physical or mental, that in the investigator's judgment precludes optimal participation in the study procedures. This includes any documented current history of liver disease, renal insufficiency, delirium, alcohol use disorder, breast-feeding mothers, acute or severe asthma, chronic obstructive pulmonary disease requiring home oxygen, GI obstruction, biliary tract disease, pancreatitis, cardiac arrhythmia, bladder or urethral obstruction, adrenal insufficiency, psychosis, or taking medications which are potent inhibitors of the CYP3A4 enzyme (such as protease inhibitors, macrolide antibiotics, or antifungals).

5. Demonstration of abusive alcohol behavior. For women, this is more than 3 drinks on any single day or more than 7 drinks per week. For men, more than 4 drinks on any single day or more than 14 drinks per week.

6. Currently taking fentanyl or methadone

7. Exhibiting the following contraindicated conditions: (1) significant respiratory depression (2) acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment (3) known or suspected gastrointestinal obstruction, including paralytic ileus (4) hypersensitivity (e.g. anaphylaxis) to oxycodone (5) patients with chronic pulmonary disease (6) elderly, cachet, or debilitated patients (7) patients with evidence of increased intracranial pressure, brain tumors, head injury, or impaired consciousness (8) patients with seizure disorders (9) pregnant and breastfeeding women, due to risks to the fetus/baby

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effect of Xtampza ER Conversion on Pain Intensity in the Last 24 Hours	Percent change in pain intensity (in the last 24 hours) from baseline to the end of the study averaged over the last 7 days before clinic visit 4 (week 6). Pain Intensity is measured on a 0-10 scale, with 0 meaning "no pain" and 10 meaning "the worst pain imaginable." As decreases in pain intensity are a sign of improvement, percent change in pain intensity is calculated as -(end of study - baseline)/baseline score.	Measured at baseline and at the end of the 6-week study
Primary	Effect of Xtampza ER Conversion on Pain Intensity in the Last 7 Days	Percent change in pain intensity (in the past 7 days) from baseline to the end of the study at clinic visit 4 (week 6). Pain Intensity is measured on a 0-10 scale, with 0 meaning "no pain" and 10 meaning "the worst pain imaginable." As decreases in pain intensity are a sign of improvement, percent change in pain intensity is calculated as -(end of study - baseline)/baseline score.	Measured at baseline and at the end of the 6-week study
Secondary	Change in Pill Swallowing Difficulty Score	Pill swallowing difficulty will be measured via a 0-10 scale with 0 being "no trouble at all" and 10 being "the greatest difficulty possible." Responses will be summarized as change from baseline scores to the end of the study at clinic visit 4 (week 6).	Measured at baseline and at the end of the 6-week study. Baseline covers current opioid medication, and week 6 covers Xtampza ER.
Secondary	Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference	The Pain Interference questions (#25-28) from the PROMIS-29 Adult Profile v2.0. Questions are measured on a 5-point scale with 1 being "Not at all" and 5 being "Very much". Responses will be summed and converted to T-Scores using the Assessment Center PROMIS Scoring Service (www.assessmentcenter.net), which rescales the raw score to a standardized T-Score with a population mean of 50 and standard deviation of 10. Pain Interference T-Scores will be summarized as the change from baseline scores to the end of the study at clinic visit 4 (week 6).	Measured at baseline and at the end of the 6-week study
Secondary	Opioid Medication Satisfaction	Opioid medication satisfaction will be measured via a 0-10 scale with 0 being "not satisfied at all" and 10 being "completely satisfied." Responses will be summarized as change from baseline score to the end of the study at clinic visit 4 (week 6).	Measured at baseline and at the end of the 6-week study. Recorded baseline for current opioid medication and in week 6 for Xtampza ER.
Secondary	PROMIS Depression, Anxiety, Satisfaction With Social Roles, and Sleep Disturbance	The Depression (#9-12), Anxiety (#5-8), Satisfaction with Social Roles (#21-24), and Sleep Disturbance (#17-20) questions from the PROMIS-29 Adult Profile v2.0. Questions are measured on a 5-point scale with 1 being "Never" and 5 being "Always". Responses for each section will be summed and converted to T-Scores using the Assessment Center PROMIS Scoring Service (www.assessmentcenter.net), which rescales the raw score to a standardized T-Score with a population mean of 50 and standard deviation of 10. These T-Scores will be summarized as change from baseline scores to the end of the study at clinic visit 4 (week 6).	Measured at baseline and at the end of the 6-week study
Secondary	PROMIS Physical Function	The Physical Function questions (#1-4) from the PROMIS-29 Adult Profile v2.0. Questions are measured on a 5-point scale with 5 being "Without any difficulty" and 1 being "Unable to do". Responses will be summed and converted to T-Scores using the Assessment Center PROMIS Scoring Service (www.assessmentcenter.net), which rescales the raw score to a standardized T-Score with a population mean of 50 and standard deviation of 10. Physical Function T-Scores will be summarized as change from baseline score to the end of the study at clinic visit 4 (week 6).	Measured at baseline and at the end of the 6-week study
Secondary	Patient Global Impression of Change (PGIC)	The subject's impression of the impact of the treatment on their pain and function will be measured with a 7-item scale (-3 = very much worse, -2 = much worse, -1 = minimally worse, 0 = no change, 1 = minimally improved, 2 = much improved, 3 = very much improved). Responses will be summarized as individual mean scores at clinic visit 4 (week 6).	Recorded in week 6.
