What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new pain medication called clonidine micropellet, given as a single injection, to help people with low back and leg pain from sciatica. The medication aims to reduce pain by blocking pain signals in the nervous system. Clonidine has been used for many years to treat hypertension and chronic pain, with recent interest in topical formulations to limit adverse events.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications before participating. You must not have taken short-acting opioids regularly, long-acting opioids, anticonvulsants with dose changes, systemic corticosteroids, or central alpha-agents like clonidine within specific time frames before screening. If you are on antidepressants or anti-anxiety medications, you must maintain a stable dose for the first 3 months of the study.

Is clonidine injection safe for humans?

Clonidine has been used safely in humans for various conditions, including pain management and spasticity, with some studies showing it does not cause significant sedation or motor impairment. However, it can cause low blood pressure, especially when taken in tablet form, but this effect is minimized with other delivery methods like patches.12345

How is the drug Clonidine Micropellets unique for treating sciatica?

Clonidine Micropellets may offer a unique approach to treating sciatica by potentially enhancing the effects of local anesthetics, as clonidine has been shown to improve the quality and duration of pain relief when used with other anesthetics in nerve blocks. This could provide longer-lasting pain relief compared to standard treatments.16789

What data supports the effectiveness of the drug Clonidine Micropellets for treating sciatica?

Research shows that clonidine, when used with other anesthetics, can improve pain relief and stability after spine surgeries. Additionally, clonidine is known to help with chronic pain conditions, suggesting it might be beneficial for sciatica as well.1891011

Are You a Good Fit for This Trial?

Adults aged 18-70 with sciatica pain (leg pain ≥4, extending below the knee) for at least 8 weeks but less than 9 months, due to a specific type of lumbar disc issue confirmed by MRI. Participants must not have had recent pain relief and should be able to distinguish back from leg pain. Pregnant women or those planning pregnancy are excluded, as well as individuals with certain medical conditions or treatments that could affect study results.

Inclusion Criteria

I can tell the difference between my back pain and leg pain.
Subjects must not have had a significant reduction in pain in the 1 to 2 weeks before Screening.
I have been diagnosed with a specific type of lower back and leg pain, confirmed by an MRI.
