What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment, GSK3858279 (an experimental drug), for individuals with chronic diabetic nerve pain who haven't found relief from other medications. Researchers aim to determine if this drug can reduce pain and is safe to use. Participants will receive either GSK3858279 or a placebo (a substance with no therapeutic effect) for comparison. This study is ideal for those with Type I or Type II diabetes who have experienced persistent, painful nerve symptoms for at least six months. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Is there any evidence suggesting that GSK3858279 is likely to be safe for humans?

Research has shown that GSK3858279 has a good safety record in earlier studies. For instance, it was tested in people with knee osteoarthritis, a joint disease, and reduced pain without causing serious side effects, indicating it was well-tolerated by patients. Another study with healthy participants also examined its safety, further supporting its tolerability.

While these results are promising, it's important to note that this treatment is still being tested for diabetic neuropathic pain. The current study focuses on determining the safety and effectiveness of GSK3858279 for this specific condition. Overall, existing data suggests that GSK3858279 is generally safe, but ongoing trials will provide more detailed information. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for diabetic neuropathy?

Researchers are excited about GSK3858279 for diabetic neuropathy because it targets the root causes of nerve pain differently than current treatments like pain relievers or antidepressants. While most existing options focus on symptom relief, GSK3858279 may work by addressing the underlying mechanisms of nerve damage, potentially offering more lasting relief. This unique approach could not only improve symptoms but also enhance overall nerve health, setting it apart from traditional therapies.

What evidence suggests that GSK3858279 might be an effective treatment for Diabetic Neuropathy?

Research shows that GSK3858279 might help reduce pain for people with Diabetic Peripheral Neuropathic Pain (DPNP). Earlier studies suggest this treatment works by blocking a protein called CCL17, which is thought to be involved in feeling pain. In other conditions, like knee osteoarthritis (OA), GSK3858279 has lessened pain and improved movement, demonstrating good safety and few side effects. Although specific data for DPNP is still being collected, these early results offer hope for those struggling to manage their pain. Participants in this trial will receive either GSK3858279 at one of two doses or a placebo to evaluate its effectiveness and safety for DPNP. ^{1 2 3 5 6}

Are You a Good Fit for This Trial?

Adults aged 18-75 with Type I or II diabetes and chronic pain from Diabetic Peripheral Neuropathic Pain (DPNP) can join this study. They should have a BMI of 18-40 kg/m^2, experience consistent pain intensity, and be able to consent. Those with cardiovascular, renal, gastrointestinal issues or other causes of neuropathy are excluded.

Inclusion Criteria

I have diabetes with painful nerve damage in my hands and feet for at least 6 months.

My average daily pain level is between 4 and 9 out of 10.

I am able to understand and sign the consent form.

Exclusion Criteria

I do not have heart, kidney, stomach, or lymph system conditions that would affect the study.

I have nerve pain in my hands or feet not caused by diabetes.

History of significant allergies to monoclonal antibodies.

• GSK3858279

Trial Overview

The trial is testing GSK3858279's effectiveness in managing DPNP against a placebo. It's randomized and double-blind, meaning neither the participants nor the researchers know who gets the real drug versus the placebo until after results are collected.

How Is the Trial Designed?

Group I: GSK3858279 60 mg Experimental Treatment 1 Intervention

Participants received GSK3858279 SC injection 60 milligram (mg) once per week for 12 weeks.

Group II: GSK3858279 360 mg Experimental Treatment 1 Intervention

Participants received GSK3858279 SC injection 360 mg once per week for 12 weeks.

Group III: Placebo Placebo Group 1 Intervention

Participants received matching placebo subcutaneous (SC) injection once per week for 12 weeks.
