If previous trials have indicated a treatment is safe and that it also shows promise in being able to treat a condition, phase 3 clinical trials begin. These involve large numbers of participants, typically more than 1,000, and are often spread between different hospitals and countries. If these trials show that a drug is safe and effective, the manufacturers can apply for a drug license.More on this topic
Phase I is the first stage of a clinical trial. It is to ensure a treatment is safe for people to take, rather than to try to treat a condition. These trials are very small, (typically around 30 people), and usually involve volunteers or sometimes patients.More on this topic

A placebo is a dummy treatment used in clinical trials. It has no effect and is given to people to compare their response to those taking the 'real' treatment. It allows researchers to test for the 'placebo effect'. This is a psychological response where people feel better even though what they are taking has no effect. By comparing people's responses to the placebo and to the drug being tested, researchers can tell whether the drug is having any real benefit.More on this topic

People with progressive MS experience a steady build up of symptoms over time, rather than relapses followed by remission. There are 2 types of progressive MS: primary progressive and secondary progressive.More on this topic
Progressive multifocal leukoencephalopathy (PML) is a serious and often fatal condition caused by a viral infection in the white matter of the brain at multiple locations. It occurs almost exclusively in people with severe immune deficiency, e.g. transplant patients on immunosuppressive medications, or AIDS patients. It is a rare side affect for people taking the MS drug natalizumab/Tysabri. The risk of developing PML is about one in 1,000 for people who taking natalizumab for more than 12 months. The risk increases after 2 years of therapy. Patients with MS should be informed about the risks of natalizumab, including PML, both before treatment and again after 2 years. They will be monitored regularly to identify PML and other potentially serious side effects as early as possible.More on this topic

A pseudo-relapse is a flare-up of symptoms caused by a raise in body temperature, for example as a result of exercise, a hot bath or a fever. No permanent harm will come from these pseudo-relapses, and once whatever is causing the raised body temperature has gone away, so will the symptoms.More on this topic
