5,7-DICHLORO-2-((ETHYLAMINO)METHYL)-8-HYDROXY-3-METHYLQUINAZOLIN-4(3H)-ONE METHANESULFONATE

Clinical trials are investigating 5,7-DICHLORO-2-((ETHYLAMINO)METHYL)-8-HYDROXY-3-METHYLQUINAZOLIN-4(3H)-ONE METHANESULFONATE in people with multiple system atrophy. The study aims to assess long-term safety and tolerability during open-label treatment. It includes a small group of participants in a Phase 2 extension study.

Table of contents

Trial overview

The available study is an open-label extension study designed to provide access to ATH434 in patients with multiple system atrophy (MSA).[1]

The trial is authorised, which means it has been approved to run.[1]

The study is interventional, so participants receive a study treatment and the research team follows what happens over time.[1]

Who can participate

The target population is people with MSA.[1]

The enrollment is 7, so this is a very small study group.[1]

The trial summary says it is for participants with MSA who are receiving open-label treatment in this extension study.[1]

Study design and phase

This is a Phase 2 trial.[1]

Phase 2 studies usually look more closely at safety and early signs of benefit in a specific patient group, and here the main focus is long-term follow-up.[1]

The intervention listed is ATH434-DP2, given by oral use at 150 mg/g milligram(s)/gram.[1]

What is measured in the study

The main endpoint is long-term safety and tolerability.[1]

The study checks the incidence and severity of adverse events and serious adverse events.[1]

It also follows changes in laboratory and vital sign results, including orthostatic measures, which are checks done when a person changes position, such as standing up.[1]

Other outcomes include exposure to ATH434, treatment discontinuations due to adverse events, and deaths.[1]

Key patient terms

Open-label means everyone in the study knows which treatment is being used.[1]

Extension study means the research continues after a main study, often to collect more long-term information.[1]

Adverse event means any unwanted medical problem that happens during a study.[1]

Serious adverse event means a major medical problem, such as one that is life-threatening or needs hospital care.[1]

Glossario

  • Multiple System Atrophy (MSA): A serious brain and nervous system disease that affects movement and body functions.
  • Open-label: A study design where both the researchers and the participants know which treatment is being given.
  • Extension study: A study that continues after a main trial, often to collect more long-term data.
  • Phase 2: A trial stage that usually examines safety and early effectiveness in a smaller group of patients.
  • Safety: How well a treatment can be used without causing serious harm.
  • Tolerability: How well patients can handle a treatment and its effects.
  • Adverse event (AE): Any unwanted medical problem that happens during a study.
  • Serious adverse event (SAE): A severe medical problem during a study, such as one that is life-threatening or needs hospital care.
  • Laboratory parameters: Results from blood or other tests used to monitor health.
  • Vital signs: Basic body measurements such as blood pressure, pulse, and temperature.
  • Orthostatic measures: Tests that check blood pressure and related changes when a person changes position, such as standing up.
  • Enrollment: The number of people planned to join the study.
