What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a new treatment, ISA-specific therapy, can alleviate pain from diabetic nerve damage, known as Painful Diabetic Peripheral Neuropathy (PDPN). Participants will receive either the experimental treatment or a placebo (a substance with no active drug) for comparison. The trial seeks individuals who have experienced diabetes and nerve pain symptoms in their lower legs for at least six months. This trial is part of a larger initiative to end long-term addiction by discovering better pain treatments. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires participants to stop using opioids or marijuana and any investigational drugs before and during the study. Additionally, you must discontinue episodic or periodic treatments for pain in the legs and feet, and you cannot start new non-drug pain treatments for diabetic nerve pain close to or during the study.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that a treatment similar to ISA-Specific Therapy, called Mirogabalin, was safe and well-tolerated in trials for diabetic nerve pain. This suggests that ISA-Specific Therapy might also be safe for people. Another study found that high-frequency spinal cord stimulation, a different treatment for diabetic nerve pain, was effective and safe. Although these studies don't directly involve ISA-Specific Therapy, they help reassure about the safety of treatments for this condition. Please note that this trial is in Phase 2, indicating early promising results, but more research is needed to confirm safety in larger groups. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about ISA-specific therapy for diabetic nerve pain because it offers a novel approach compared to current treatments like gabapentin, pregabalin, or duloxetine. While these standard options primarily aim to manage symptoms by altering neurotransmitter levels, the ISA-specific method might target the underlying pathways of nerve pain more directly. This approach could potentially offer more effective pain relief with fewer side effects, making it a promising alternative for those who struggle with current medications.

What evidence suggests that this treatment might be an effective treatment for diabetic nerve pain?

Research has shown that ISA-specific therapy, which participants in this trial may receive, might help with diabetic nerve pain. In a study involving many patients with this type of pain, mirogabalin provided significant relief. Early studies also suggest that ISA-specific therapy can increase the number of nerve fibers in the skin, potentially aiding nerve regrowth and reducing pain. These findings offer hope that ISA-specific therapy could effectively manage diabetic nerve pain. ^{1 2 3 5 6}

I have diabetic neuropathy.

I experience pain in my legs, feet, toes, or ankles.

Exclusion Criteria

I have had a heart attack or stroke.

My diabetes treatment has been stable for at least 3 months with no expected changes.

Published Research Related to This Trial

In a phase III study involving 834 Asian patients with diabetic peripheral neuropathic pain, mirogabalin demonstrated significant pain relief, particularly at the 30 mg/day dose, compared to placebo, with a notable change in average daily pain score of -1.81 (P = 0.0027).

Mirogabalin was well tolerated across all doses, with most side effects being mild to moderate, including nasopharyngitis, somnolence, and dizziness, indicating a favorable safety profile for this new treatment.
