Relapsing-remitting multiple sclerosis
MONDO:0005314The most common clinical variant of multiple sclerosis, characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. Common clinical manifestations include loss of visual (see optic neuritis), motor, sensory, or bladder function. Acute episodes of demyelination may occur at any site in the central nervous system, and commonly involve the optic nerves, spinal cord, brain stem, and cerebellum.

Experimental MS drug tested in kids, but study halted early
Disease control Stopped earlyThis study tested the drug alemtuzumab in children aged 10 to 18 with relapsing-remitting multiple sclerosis (MS) whose disease was still active despite other treatments. The goal was to see if the drug could reduce new brain lesions and improve quality of life. However, the tria…

New drug telitacicept tested for MS Flare-Ups
Disease control Stopped earlyThis phase 2 trial tested telitacicept (RC18) in 8 people with relapsing-remitting multiple sclerosis. The drug aims to reduce relapses by targeting B cells. The study was terminated early, so we have limited data on safety and effectiveness.

New MS drug trial for japanese patients shows promise but study stopped early
Disease control Stopped earlyThis study tested the drug natalizumab in 21 Japanese adults with relapsing-remitting multiple sclerosis (MS). The goal was to see if injections under the skin every 4 weeks could reduce new brain lesions over 24 weeks, and to check safety for up to 48 weeks. The study was termin…
