What is the purpose of this trial?

This trial tests a new treatment called MN-166 (Ibudilast) to determine its effectiveness for people with ALS, a nerve disease that weakens muscles. Researchers aim to assess whether MN-166 is safe and effective compared to a placebo, which contains no active medicine. Participants will take either MN-166 or a placebo for 12 months, followed by MN-166 for another 6 months. This trial may suit individuals diagnosed with ALS within the last 18 months who can swallow pills. As a Phase 2, Phase 3 trial, it measures the treatment's effectiveness in an initial, smaller group and represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking ALS treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but if you are using riluzole or edaravone, you must be on a stable dose or have completed a treatment cycle before starting the study drug.

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

Research shows that MN-166, also known as ibudilast, has been tested for safety in people with ALS (Amyotrophic Lateral Sclerosis). Previous studies examined how well participants tolerated this treatment. These studies did not find major changes in brain inflammation or certain protein levels in the blood, indicating the drug did not cause unexpected effects in these areas.

Although detailed safety data from these studies aren't included here, the treatment's progression to a Phase 2b/3 trial indicates it has passed initial safety tests. This suggests earlier research found it to be generally safe for humans. However, individual experiences can vary, so staying informed and consulting with doctors is important when considering joining a trial. ^{1 2 3 4 5}

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

Researchers are excited about MN-166 for ALS because it offers a novel approach by potentially modulating inflammation and neuroprotection. Unlike many current ALS treatments, which primarily focus on managing symptoms, MN-166 aims to slow disease progression by targeting specific pathways involved in inflammation and neurodegeneration. This unique mechanism could provide new hope for extending mobility and quality of life for those with ALS.

What evidence suggests that MN-166 might be an effective treatment for ALS?

Research is investigating MN-166, also known as ibudilast, for its potential to treat ALS (amyotrophic lateral sclerosis). In this trial, participants will receive either MN-166 or a placebo. Some studies have not shown significant changes in certain disease markers, but researchers continue to assess whether MN-166 can enhance muscle strength and quality of life. Those using MN-166 aim to determine if it can improve overall functioning. The ongoing research seeks to fully understand its potential benefits for ALS patients. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• MN-166
• Placebo

Trial Overview

The study tests MN-166 against a placebo over 12 months to see if it's effective and safe for ALS patients, followed by everyone getting MN-166 for another six months. It's randomized (participants are put into groups by chance) and double-blind (neither participants nor researchers know who gets what treatment).

How Is the Trial Designed?

Group I: MN-166 Experimental Treatment 1 Intervention

Subjects will take MN-166 10 mg capsules, up to 50 mg twice a day for 12 months.

Group II: placebo Placebo Group 1 Intervention

Subjects will take up to 5 matching placebo capsules twice a day for 12 months.

MN-166 is already approved in Japan for the following indications:

Approved in Japan as Ibudilast for:

• Anti-inflammatory

In a study of 31 ALS patients treated with edaravone, there were no significant improvements in functional measures compared to 50 historical ALS patients not treated with the drug, indicating that edaravone may not be effective for this population.

While edaravone was generally safe over the 6-month observation period, treated patients experienced a significant decrease in kidney function and a worsening quality of life, suggesting potential adverse effects despite the lack of efficacy.

The MND-SMART trial aims to evaluate the efficacy of trazodone and memantine in treating motor neuron disease (MND) with up to 531 participants, using a novel adaptive trial design that allows for efficient evaluation of multiple drugs.

The primary outcomes of the trial are the ALS Functional Rating Scale and survival, with the design reducing the time, cost, and number of participants needed to assess drug effectiveness, while minimizing exposure to ineffective treatments.

A review of 53 new drugs evaluated in clinical trials for ALS from 2020 to 2022 identified five promising candidates, including AMX0035, which has recently been approved by the FDA, marking it as the third drug approved for ALS treatment after riluzole and edaravone.

The review categorized these drugs into eight mechanistic groups, highlighting a diverse range of approaches being explored to combat ALS, with 13 drugs currently in phase 3 trials, indicating ongoing efforts to find more effective treatments.

In a 36-week open-label trial involving 35 ALS participants, ibudilast treatment at doses up to 100 mg/day did not significantly reduce glial activation or neuroaxonal loss, as measured by PBR28-PET and serum Neurofilament light (NfL).

The treatment was associated with a high incidence of adverse events, with 86% of participants experiencing at least one possibly drug-related side effect, leading to dose reductions in 37% of participants and early discontinuation in 31%.

In a phase II trial involving 107 ALS patients, lithium carbonate did not slow the progression of the disease, showing a greater decline in function compared to historical controls, which raises concerns about its efficacy.

The study also noted an increase in adverse events among patients taking lithium, leading to the conclusion that it is not a recommended treatment for ALS due to safety concerns and lack of therapeutic benefit.

In the first three years of edaravone's availability for ALS treatment in the US, over 5200 patients were treated, and the drug was shown to slow the decline in physical function, although it was associated with various adverse events (AEs) including fatigue, muscular weakness, and respiratory issues.

The safety profile of edaravone remained consistent with previous clinical trials, with no new safety concerns identified, although serious adverse events included pneumonia and respiratory failure, and there were 687 reported deaths, primarily attributed to ALS progression.
