How Fasevia works

Fasevia tracks research into treatments for diseases that still have no cure. For each disease it shows what is being tested, which phase each candidate is in, what was abandoned and the latest news, in Portuguese, Spanish and English.

Where the data comes from

• Official clinical trial registries (ClinicalTrials.gov): start, phase changes, closures and results of each study.
• Scientific papers (PubMed): clinical trials and reviews published in medical journals.
• Health agencies: announcements and approvals from the US FDA.
• News and press releases from the companies developing the treatments.

How every update is reviewed

Every day a program checks these sources and picks out what changed. An AI summarizes each item under strict rules: use only what the source says, flag results that are preliminary, in few patients or in animals, and never promise a cure. Nothing is published without a person's approval. Every update links to its original source.

What each phase means

• Lab or pilot: early research in cells, animals or a handful of patients.
• Phase 1: tests safety in a small group of people.
• Phase 2: checks whether it works and at what dose.
• Phase 3: confirms the effect in many patients. It is the final step before filing for approval.
• Filed for approval: a health agency reviews the data before allowing its use.

Limits

Fasevia is informational and is not medical advice. Most treatments being tested never reach the market. If you live with one of these diseases, bring your questions to your doctor, including if you'd like to join a clinical trial.
