A Phase 2b Study To Evaluate The Efficacy And Safety Profile Of PF-06651600 And PF-06700841 In Active Non-segmental Vitiligo Subjects

Active Non-segmental Vitiligo Clinical Trial

Official title:
A PHASE 2B RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, MULTICENTER, DOSE-RANGING STUDY TO EVALUATE THE EFFICACY AND SAFETY PROFILE OF PF-06651600 WITH A PARTIALLY BLINDED EXTENSION PERIOD TO EVALUATE THE EFFICACY AND SAFETY OF PF-06651600 AND PF-06700841 IN SUBJECTS WITH ACTIVE NON-SEGMENTAL VITILIGO

Clinical Trial Summary

This is a Phase 2b, randomized, double blind, parallel group, multicenter study with an extension period. The study will have a maximum duration of approximately 60 weeks. This includes an up to 4 weeks Screening Period, a 24 week dose ranging period, an up to 24 week extension period and a 8 week Follow up Period.

Interventional studies are often prospective and are specifically tailored to evaluate direct impacts of treatment or preventive measures on disease.

Observational studies are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods.

Expanded access is a means by which manufacturers make investigational new drugs available, under certain circumstances, to treat a patient(s) with a serious disease or condition who cannot participate in a controlled clinical trial.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
