<h2>Dazucorilant</h2>
Unbalanced levels of cortisol (a stress hormone) have been reported in people with ALS. Long exposure to higher levels of cortisol may increase inflammation in the nervous system. Dazucorilant is a small molecule that modulates cortisol activity which may reduce the neurotoxic effects of prolonged cortisol exposure. Therefore, it may slow functional loss and disease progression.
<h2>Study design</h2>
DAZALS is a phase 2 double-blind, randomized, placebo-controlled study. This means that the efficacy of dazucorilant is compared to a placebo. The placebo looks exactly like dazucorilant but contains no active drug. Participants will be randomly assigned to either the placebo or dazucorilant. You will have a two-thirds (2/3) chance of receiving dazucorilant. Neither you nor your study doctor or the study staff will know which treatment you are receiving.

During the study there will be 10 research visits over a period of 28 weeks. 7 visits will take place at the research centre and 3 visits will be by telephone. At the last visit in week 24, you can choose to continue with dazucorilant as part of an ‘open-label’ study period. You will then continue visits both at the research centre and by telephone for up to 140 weeks. If you do not wish to participate in the open-label extension or are not eligible, you will be asked to continue study visits over the phone for up to 132 weeks.

The study drug (refers to both dazucorilant and placebo) is a softgel capsule packaged in a blister card. Study drug (4 capsules in total) should be taken by mouth once a day with food and 240 ml water, at approximately the same time each day.
<h2>Can I participate in the study?</h2>
The main criteria to participate in this study are:
<ul>
 	<li>You are diagnosed with ALS.</li>
 	<li>You are able to swallow capsules.</li>
 	<li>If you are taking an approved treatment for ALS, you must be on a stable dose of that treatment prior to entering this study.</li>
</ul>
<h2>Registration and more information</h2>
If you are interested in this study and fit the above criteria, please contact one of the participating TRICALS centres below (contact details can be found by clicking on ‘read more’). They can provide you with more information and discuss any questions you may have. If you experience difficulty contacting a centre, you may reach out directly to the TRICALS operational team at info@tricals.org for support in this process.

DAZALS trial

Industry trial

<h2><strong>AMX0035</strong></h2>
AMX0035 consists of a combination of two molecules: tauroursodeoxycholic acid (TUDCA) and sodium phenylbutyrate. Both were previously shown to be safe and well tolerated. The combination of the two drugs is believed to decrease nerve cell damage in people living with ALS.
<h2><strong>Study overview</strong></h2>
This phase 3 study is a double-blind, randomized, placebo-controlled study. This means that we compare the effect of AMX0035 against the effect of a placebo. A placebo is a drug without an active ingredient, a 'fake drug'. The study drug and placebo are supplied in a sachet and must be dissolved in 1 cup of water. Either treatment should be taken orally (ingested) daily for 48 weeks. Participants will be randomly assigned to receive the placebo or AMX0035 treatment. The participant and the research team do not know which treatment the participant is receiving.

During a period of 1 year, participants will visit the research centre approximately 6 times for examinations. They will furthermore be contacted approximately 9 times by telephone or video calling.
<h2><strong>Key Eligibility Criteria</strong></h2>
The main criteria to participate in this study are:
<ul>
 	<li>You are diagnosed with ALS</li>
 	<li>The duration of illness from the first symptoms is no longer than 24 months</li>
 	<li>Your lung function is at least 55%, without using a ventilator</li>
 	<li>You must not be pregnant or breast-feeding for the entire duration of the study</li>
 	<li>If you have or are considering having diaphragm pacing during the study, you cannot participate</li>
 	<li>When using Riluzole: a stable dose of ≥30 days prior to participation</li>
</ul>
Participants can continue their treatment with Riluzole for the entire duration of the study.

Amylyx is looking to enrol 600 participants worldwide. Currently, the study is active in the following European countries: the United Kingdom, Ireland, the Netherlands, Spain, Sweden, Italy, France, Poland, Belgium, Germany and Portugal.
