Tiziana falters following mid-stage results for multiple sclerosis asset
Tiziana Life Sciences (TLS) fell 13% on Monday despite phase 2a results for intranasal foralumab meeting dual primary endpoints in non-active secondary progressive multiple sclerosis. The 50 μg dose showed significant neuroinflammation reduction vs. placebo, while the 100 μg dose did not. Both doses were well-tolerated, and MFIS scores improved in treatment arms.
