ACCIÓN: Ensayo de agregar buprenorfina, TCC y TMS para mejorar los resultados de la terapia con opioides a largo plazo para el dolor crónico (ACTION)

2 de noviembre de 2026 actualizado por: Medical University of South Carolina

Ensayo secuencial de adición de buprenorfina, tratamiento cognitivo conductual y estimulación magnética transcraneal para mejorar los resultados de la terapia con opioides a largo plazo para el dolor crónico (ACTION)

This study will sequentially evaluate three novel and scalable interventions for at-risk individuals on long term opioid therapy for chronic pain: (1) low-dose transdermal buprenorphine initiation without a period of opioid withdrawal; (2) a brief Cognitive Behavioral Intervention for pain (CBI); and (3) "accelerated" rTMS over the left dorsolateral prefrontal cortex, by examining standardized repeated measures of clinical outcomes at baseline, during treatment, and at 4-, 12-, 24- and 52-week follow-up.

Descripción general del estudio

Descripción detallada

With little evidence available to guide the provision of clinical care for patients on long-term opioid therapy (LTOT) in whom the risks outweigh the benefits, major questions remain about optimizing the risk/benefit profile of LTOT, including: how to best engage patients voluntarily in this process; the safety, tolerability and effectiveness of newer treatment approaches; and optimal treatment selection. The primary objective of the proposed study is to begin to systematically address gaps in this important area to improve pain, reduce risk, and improve quality of life for individuals on LTOT.

Experimental: etiqueta abierta BUP

Buprenorphine patch dosing will be individualized based on each participant's current morphine-equivalent dose (per package insert/recommendations; between 5mcg and 20mcg per hour). Dosage based on baseline MEQ (<30 MEQ = 5mcg/hr patch, 30-80 MEQ =10-15mcg/hour patch; >80 MEQ = 20mcg/hour patch), which will remain on for 7 days (Phase Ia Days 1-7), as tolerated

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Intervention Tolerability
Periodo de tiempo: up to Day-13

(a) Tolerability of open-label transdermal buprenorphine, defined as the proportion of eligible patients who do not discontinue buprenorphine due to adverse effects, preference, or intolerance. (b) Tolerability of TMS/sham, defined as tolerating 10 sessions of accelerated rTMS

up to Day-13
Pain Severity
Periodo de tiempo: up to Day-20

Pain severity is measured by the Brief Pain Inventory (BPI) Severity Scale and is typically scored as the mean of the four severity items ("average," "worst," "least," "now," range 0-10) with a higher score being worse.

This outcome will be measured after both the buprenorphine vs. placebo trial and the TMS vs. sham trial.

up to Day-20

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Buprenorphine Transition Rate
Periodo de tiempo: Day-20

Buprenorphine transition rate defined as the proportion of participants who spontaneously elect to continue buprenorphine after Phase I.

Day-20
Quality of Life
Periodo de tiempo: up to Day-20

Patient-Reported Outcomes Measurement Information System (PROMIS)-Preference (PROPr) score summarizes multiple domains into a single score anchored at 0 (as bad as dead) and 1 (perfect or ideal health). This score quantifies the value that individuals place on different states of health.

PROPr is calculated from the scores for the 7 PROMIS domains: Cognition, Depression, Fatigue, Pain Interference, Physical Function, Sleep Disturbance, and Ability to Participate in Social Roles and Activities.

This outcome will be measured after both the buprenorphine vs. placebo trial and the TMS vs. sham trial.
