Brief Summary

Abdominal pain in chronic pancreatitis (CP) affects up to 90% of patients during the course of their disease, and response to currently available therapies is suboptimal and unpredictable. The proposed clinical trial will evaluate the predictive capability of Pancreatic Quantitative Sensory Testing (P-QST) - a novel assessment of neurosensory phenotyping- for improvement in pain in patients with CP who are undergoing medically-indicated invasive treatment with endoscopic therapy or surgery.

Detailed Description

P-QST has been shown to be able to phenotype patients with CP into nociceptive patterns according to degree of central sensitization. As a tool to identify baseline nociceptive pattern in patients with painful CP, P-QST will be performed at baseline prior to planned invasive treatment with endoscopic therapy or decompressive surgery. We will evaluate the ability of P-QST to predict response to invasive treatment for painful CP, and to develop a predictive model for individualized prediction of treatment response.

Patients will undergo pre-procedure P-QST testing before undergoing scheduled invasive treatment as directed by their treating gastroenterologist. The date of first endoscopic therapy or surgery will be used to calculate follow-up timepoints, which will be scheduled at 3, 6, and 12 months after the first endotherapy session or surgery. At each follow-up time point, patients will answer questions about their pain. In addition, patients will complete patient reported outcome tools (HADS, PCS instruments) and the Patient Global Impression of Change. Serum and urine samples will be obtained at baseline and at 6-month follow-up timepoints.

Primary Outcome Measures
NameTimeMethod
Average Pain Scoresix months post procedure

The primary outcome of the study is average pain score at 6 months post-procedure based on single-question numeric rating scale (NRS) (Scale of 0 to 10 how intense abdominal pain has been on average over the past 7 days (Scale: 0=No pain, 10=Worst pain Imaginable.)

Secondary Outcome Measures
NameTimeMethod
Change from baseline in Single-question NRS scoreat 12 months.

Single-question NRS at 12 months after intervention (Scale 0 = no pain to 10 = worst pain imaginable)

Change from baseline in Seven Day Pain Diary Score12 months after intervention.

The 7-day pain diary average score at 12 months after intervention. (Scale 0 = no pain to 10 = worst pain imaginable)

Pain relief of ≥50%12 months after intervention

Percentage of patients with ≥50% at 12 months after intervention.

Change from baseline on the Pain Catastrophizing Scale (PCS)Baseline, 3, 6, and 12 months

The PCS is a validated self-reported tool that scores the patient tendency to catastrophize about pain or potential pain. Possible scores range from 0 to 42 (higher scores reflect more catastrophizing tendencies).

Pain relief of ≥30%12 months

Percentage of patients with ≥30% at 12 months after intervention

Number of patients using prescription opioids for pain control at time of assessment12 months

Opioid use (yes,no) at 12 months.

Mean reported daily opioid dose for patients using prescription opioids at time of assessment12 months

Opioid dose (continuous variable in milligrams of morphine equivalent) at 12 months.

Change from baseline on the Patient Reported Outcomes Measurement Information System (PROMIS) Global Health ScaleBaseline, 3, 6, and 12 months

The PROMIS Global Health Questionnaire is a validated self-reported tool that scores both mental and physical health at the time of assessment. Possible scores for both Mental and Physical Health range from 7 to 35 (lower score corresponds to poorer physical or mental health).

Patient Global Impression of Change (PGIC) Scale3, 6, and 12 months

The PGIC is a validated self-reported tool that scores the patient's impression of change from baseline of their pain and overall health. Possible scores range from 1 to 7 (higher score corresponds to improvement).

Change from baseline on the Hospital Anxiety and Depression Scale (HADS)Baseline, 3, 6, and 12 months

The HADS is a validated self-reported tool that screens for symptoms of anxiety and depression. Possible scores range from 0 to 21 (higher scores reflect more severe symptoms of anxiety or depression).

Change from baseline on the Patient Reported Outcomes Measurement Information System (PROMIS) Neuropathic Pain ScaleBaseline, 3, 6, and 12 months

The PROMIS Global Health Questionnaire is a validated self-reported tool that scores neuropathic pain characteristics at the time of assessment. Possible scores range from 5 to 25 (higher score corresponds to more neuropathic pain characteristics).

Change from baseline on the Patient Reported Outcomes Measurement Information System (PROMIS) Nociceptive Pain ScaleBaseline, 3, 6, and 12 months

The PROMIS Global Health Questionnaire is a validated self-reported tool that scores nociceptive pain characteristics at the time of assessment. Possible scores range from 5 to 25 (higher score corresponds to more nociceptive pain characteristics).

Change from baseline on the Patient Reported Outcomes Measurement Information System (PROMIS) Pain Interference ScaleBaseline, 3, 6, and 12 months

The PROMIS Global Health Questionnaire is a validated self-reported tool that scores pain interference with aspects of daily life at the time of assessment. Possible scores range from 6 to 30 (higher score corresponds to more pain interference with daily activities).

Change from baseline on the Modified Brief Pain Inventory Short Form (mBPI-SF)Baseline, 3, 6, and 12 months

The mBPI-SF is a validated self-reported tool that evaluates pain severity and pain interference with daily activities at the time of assessment. Possible scores for pain severity range from 0 to 40 (higher scores reflect more severe pain); possible scores for pain interference range from 0 to 70 (higher scores reflect more pain interference with daily life).

The EORTC QLQ-C30 is a validated self-reported tool measuring quality of life that reports scores on global health (quality of life), functioning (physical, role, emotional, cognitive, social), and symptoms (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties). All scores range from 0 to 100. A high score on quality of life indicates higher quality of life; a high score on a functioning scale indicates a higher level of functioning, and a high score on a symptom scale indicates a higher level of symptoms.

Change from baseline on the Comprehensive Pain Assessment Tool for Pancreatitis Short Form (COMPAT-SF)Baseline, 3, 6, and 12 months

The COMPAT-SF is a validated self-reported tool specifically designed for patients with pancreatic disease. Scores for pain severity (average, worst, and least) range from 0 to 10 (higher corresponds to more pain); scores for pain triggers (including food, exercise, and thermal changes) are scored on a scale from never to always (never, rarely, sometimes, very often, always); scores for pain symptom characteristics (cramping, shooting, stabbing) are scored on a scale from 0 (none) to 10 (worst possible).
