Study summary

The EPPIC (Easing Pelvic Pain Interventions Clinical Research Program) study evaluates an ultra-brief, 4 session cognitive behavioral pain treatment transdiagnostic in design for urologic chronic pain syndrome (UCPPS) with clinical and practical advantages over existing behavioral therapies whose length and focus limits their adoption by clinicians and coverage for mechanistically similar comorbidities. A theoretically informed, practical, empirically grounded approach will systematically unpack CBT's working mechanisms, clarify for whom it works, ease dissemination, appeal to patients, providers, payers, and policy makers in the COVID-19 era favoring low resource intensity treatments, and reduce cost and inefficiencies associated with high intensity therapies whose complexity, length, and scarcity restricts uptake and impact.

Read the detailed description

Urologic chronic pelvic pain syndrome (UCPPS) encompasses several common, costly diagnoses including interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome that are poorly understood and inadequately treated. Their prolonged personal and economic costs are amplified by the frequent co-occurrence of a cluster of centralized pain conditions (particularly irritable bowel syndrome 3 [IBS]) but also fibromyalgia [FMS], chronic headache, chronic fatigue, etc.) called Chronic Overlapping Pain Conditions (COPC). Clinically, the notion that these syndromes share a centralized pain phenotype with a fundamental disturbance in pain or sensory processing dovetails with our preliminary research showing that a novel transdiagnostic behavioral treatment emphasizing a single common mechanistic pathway (i.e. inflexible cognitive style) reduces severity of both targeted (IBS) and untargeted multisymptom COPCs that include (but is not limited to) to UCPPS, FMS, chronic fatigue, and chronic headache. If effective in a larger scale study, a transdiagnostic UCPPS treatment would offer a more efficient, accessible, and broadly useful strategy for improving chronic pelvic pain and its most frequent and complicating comorbidities. To this end, the investigators will randomize 240 UCPPS subjects (18-70 yrs.) of any gender and race to a 4-session version of CBT that teaches skills for self-managing UCPPS symptoms (e.g. pelvic pain, urinary symptoms such as urinary frequency, urgency) with minimal clinician oversight (MC-CBT) or a four-session non-specific education/support control (EDU). Efficacy assessments will be administered at pre-treatment baseline and two weeks after the end of the 10-week acute phase using the patient version of the Clinical Global Impressions Scale and validated with the physician version rated by MD assessors blind to treatment assignment. The investigators hypothesize MC-CBT will deliver significantly greater UCPPS symptom improvement than EDU (Aim 1). Additional aims include characterizing the durability of effects 3- and 6 months post treatment (Aim 2). To increase the efficacy and efficiency of behavioral pain treatments, the investigators draw upon Beck's transdiagnostic cognitive model to characterize the precise cognitive procedures and corresponding operative processes (e.g., cognitive distancing, context sensitivity, coping flexibility, repetitive negative thought) that drive MC-CBT induced UCPPS symptom relief relative to EDU (Aim 3) as well as baseline patient variables that moderate differential response (Aim 3) with the ultimate goal of more proactive patient-treatment matching fundamental to the goals of personalized medicine. By applying innovative statistical modelling (e.g. dominance analysis, Randomized Explanatory Trial analyses) to study aims in the context of a rigorously designed behavioral trial, the researchers expand the portfolio of nondrug pain treatments for UCPPS and co-aggregating COPCs to include one whose brevity, convenience, and transdiagnostic design "meets patients where they are" and addresses the practical (access, complexity, cost), clinical (breadth, durability, magnitude of effects, patient preference) and conceptual (untargeted comorbidities, non-pain somatic symptoms) challenges that have impeded uptake and public health impact of evidence-based behavioral pain treatments at a time when our most vulnerable high impact pain patients are in greatest need.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Clinical Global Impressions - Improvement Scale Patient Version (CGI-I)

    Widely used measure of global improvement of symptoms from baseline. To optimize rigor, clinician version by independent MD assessors "blind" to treatment assignment will also measure global severity of pelvic pain and urinary symptoms from baseline and validate patient-reported global improvement as a marker of clinical response. Global improvement is a core domain recommended for conducting clinical trials of the efficacy and effectiveness of treatments for chronic pain according to Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT)

    Time frame: 12 weeks after pre-treatment baseline

Secondary outcomes

When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
