What is the purpose of this trial?

This trial explores three new approaches to assist people with chronic pain on long-term opioid therapy. It tests a low-dose buprenorphine skin patch, a brief cognitive behavioral therapy session for pain, and a type of brain stimulation called "accelerated" rTMS (repetitive transcranial magnetic stimulation). The trial aims to evaluate the effectiveness of these treatments in reducing pain and improving quality of life. It seeks participants who have used daily prescription opioids for at least 90 days and experience issues like dizziness, nausea, or fatigue from their current medications. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to receive these innovative therapies.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot participate if you are on certain medications like methadone, buprenorphine for opioid use disorder, naltrexone, or medications that prolong the QTc interval.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that buprenorphine might be a safer option for treating chronic pain. The FDA has approved it for both short-term and long-term pain relief, as well as for assisting individuals with opioid addiction. Studies have found that buprenorphine can effectively manage pain without causing serious side effects like withdrawal symptoms.

Transcranial Magnetic Stimulation (TMS) is also considered safe and well-tolerated for people with chronic pain. TMS is a non-invasive treatment that uses magnetic fields to stimulate brain cells. Most reports indicate it causes only minor side effects.

Both treatments appear promising in terms of safety, based on past research and their current uses. However, the researchers are still studying the safety of these treatments for chronic pain in this specific trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for chronic pain because they combine buprenorphine with cognitive behavioral therapy (CBT) and transcranial magnetic stimulation (TMS), offering a multifaceted approach that could enhance pain management. Unlike standard treatments like opioids, NSAIDs, or physical therapy, buprenorphine provides pain relief with a lower risk of addiction. CBT targets the psychological aspects of chronic pain, potentially improving outcomes by addressing the mind-body connection. Meanwhile, TMS offers a non-invasive way to stimulate brain activity and may provide pain relief without the side effects commonly associated with medication. This comprehensive strategy could revolutionize how chronic pain is treated by addressing both physical and mental components.

What evidence suggests that this trial's treatments could be effective for chronic pain?

Research shows that buprenorphine, one of the treatments in this trial, effectively manages chronic pain. In 23 out of 24 studies, it worked as well as other strong painkillers like morphine and oxycodone. It is also considered safer with fewer side effects, making it a good option for long-term use.

Studies have indicated that transcranial magnetic stimulation (TMS), another treatment option in this trial, helps reduce pain. This treatment uses magnetic fields to stimulate brain cells, showing benefits in treating different types of pain. These early findings suggest TMS could be an effective part of pain management. ^{3 5 6 7 8}

In a pilot study involving 26 participants with opioid use disorder, initiating buprenorphine extended-release injection (BUP-XR) after a single 4 mg dose of transmucosal buprenorphine (BUP-TM) was found to be safe and well tolerated, with no serious adverse events reported.

Participants showed significant improvement in withdrawal symptoms, with Clinical Opiate Withdrawal Scale (COWS) scores decreasing from an average of 14.6 to 4.2 within 24 hours after receiving BUP-XR, indicating effective management of cravings and withdrawal.

In a study involving 280 patients with moderate to severe musculoskeletal pain, the buprenorphine transdermal system (BTDS) demonstrated noninferior effectiveness compared to sustained-release tramadol, with both treatments significantly reducing pain levels over an 8-week period.

The safety profiles of BTDS and tramadol were comparable, indicating that BTDS is a viable alternative for patients whose pain is not adequately managed by nonsteroidal anti-inflammatory drugs.

Repetitive transcranial magnetic stimulation (rTMS) is a safe and effective treatment for chronic pain, with 12 randomized controlled trials involving 350 patients showing significant pain relief, particularly with high-frequency stimulation on the motor cortex.

While low-frequency rTMS showed no benefit, high-frequency rTMS produced short-term pain relief and a long-lasting analgesic effect, although the optimal stimulation parameters and target sites still need further investigation due to variability in study results.

In a case study of a 62-year-old male with drug-resistant neuropathic pain due to spinal cord injury, 10 Hz repetitive transcranial magnetic stimulation (rTMS) resulted in significant pain reduction, with a 30% decrease in sternum pain and a 29% decrease in left foot pain after 6 weeks of treatment.

rTMS was safe and did not interfere with the patient's intrathecal baclofen pump, and it also led to substantial improvements in anxiety and depression scores, indicating its potential as an effective treatment for neuropathic pain.

Repetitive transcranial magnetic stimulation (rTMS) shows promise as a novel intervention for opioid use disorder (OUD), with a case report indicating a significant reduction in cravings for heroin and cocaine by approximately 60% to 82% after 7 sessions targeting the left dorsolateral prefrontal cortex.

This case highlights the potential of rTMS to augment medication-assisted treatment (MAT) for individuals with OUD, especially for those who continue to experience cravings despite comprehensive treatment, suggesting a need for further research in this area.

In a pilot trial involving 22 participants with opioid use disorder undergoing methadone maintenance therapy, repetitive transcranial magnetic stimulation (rTMS) did not significantly reduce cravings or heroin use compared to a sham treatment.

However, rTMS was associated with significant improvements in depressive symptoms, impulse control, and attention, suggesting potential benefits for mental health aspects in individuals with opioid use disorder.

Buprenorphine shows promise for treating chronic pain in children due to its long duration of action and metabolism that is largely independent of renal function, making it potentially safer for those with kidney issues.

However, there is a significant lack of pediatric-specific pharmacokinetic and pharmacodynamic data, and the risk of respiratory depression remains uncertain, highlighting the need for further research before widespread use in children.

A survey of 3,255 patients indicated that transdermal buprenorphine is effective for managing chronic pain, with 81% of respondents reporting good or very good pain relief, especially beneficial for those with stable cancer and non-cancer pain.

Adverse effects were generally mild and similar to other opioids, with only 4% experiencing local erythema and 1% pruritus, suggesting that the buprenorphine patch may be a safer alternative for patients who have had side effects from oral pain medications.

In a study of 1,465 patients with moderate to severe pain, transdermal buprenorphine led to an average reduction of 25.1 points on the visual analog scale (VAS) over a median treatment period of 3.7 months, with 88.4% of patients experiencing at least a 10% decrease in pain.

The treatment was well-received, with 82.5% of patients rating it as 'Good' or 'Very Good', and while 50.2% experienced adverse events, only 4.0% were considered serious, indicating a favorable safety profile.

A post hoc analysis of 354 patients using the buprenorphine transdermal system (BTDS) for chronic pain showed that those who also used immediate-release (IR) opioids experienced significant improvements in pain intensity and interference without an increase in adverse events.

The study supports the safe and effective use of IR opioids as supplemental analgesia alongside BTDS, as patients reported similar pain relief and maintained treatment persistence over 6 months.
