MSA Trial Tracker

Tracker extracts data from ClinicalTrials.gov, a database managed by the National Library of Medicine (NLM) at the National Institutes of Health (NIH) in Bethesda, Maryland.

Understanding Clinical Trial Phases:

Phase 1: A phase of research to describe clinical trials that focus on the safety of a drug. They are usually conducted with healthy volunteers, and the goal is to determine the drug's most frequent and serious adverse events and, often, how the drug is broken down and excreted by the body. These trials usually involve a small number of participants.

Phase 2: A phase of research to describe clinical trials that gather preliminary data on whether a drug works in people who have a certain condition/disease (that is, the drug's effectiveness). For example, participants receiving the drug may be compared to similar participants receiving a different treatment, usually an inactive substance (called a placebo) or a different drug. Safety continues to be evaluated, and short-term adverse events are studied.

Phase 3: A phase of research to describe clinical trials that gather more information about a drug's safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. These studies typically involve more participants.

Phase 4: A phase of research to describe clinical trials occurring after the FDA has approved a drug for marketing. They include postmarket requirement and commitment studies that are required of or agreed to by the study sponsor. These trials gather additional information about a drug's safety, efficacy, or optimal use.

Phase Not Applicable: Describes trials without FDA-defined phases, including trials of devices or behavioral interventions.

Understanding the Status of active studies:

Not yet recruiting: The study has not started recruiting participants.

Recruiting: The study is currently recruiting participants.

Active, not recruiting: The study is ongoing, and participants are receiving an intervention or being examined, but potential participants are not currently being recruited or enrolled.
