About Clinical Trials
A clinical trial is a research study that explores whether a medical strategy, investigational treatment or device is safe and effective for humans. All potential new treatments go through a set of clinical trial phases under controlled conditions.
Phase 1 tests safety in humans by giving the treatment or drug to healthy volunteers.
Phase 2 tests safety and effectiveness in patients living with the disease being studied.
Phase 3 tests safety and confirms effectiveness in patients with the disease and studies a larger group of people than in a Phase II trial.
Phase 4 tests the drug’s effect in various populations and any side effects associated with long-term use after the drug is approved.
Regulatory agencies – for example, the U.S. Food & Drug Administration (FDA) or the European Medicines Agency (EMA) – determine whether the treatment can be prescribed by physicians to patients.
There are numerous benefits of participating in a clinical trial, including:
- Gaining early access to investigational medication
- Contributing to medical research
- Potentially helping future generations of patients diagnosed with Primary Hyperoxaluria
