** Shares of drug developer Immunovant IMVT.O fall 3.8% to $18.08
** Company says its drug, batoclimab, helped improve the ability to perform daily activities in some patients with a type of chronic autoimmune disease affecting muscles in a late-stage trial
** The drug was tested for myasthenia gravis — a disease that affects the muscles used for eye movement, facial expressions, chewing, swallowing and speaking
** UBS analysts, however, say the late-stage data "underwhelms high expectations" set by Argenx's ARGX.BR flagship drug Vyvgart
** IMVT says batoclimab also met the goal of a mid-stage trial testing in patients with a type of neurological disorder called chronic inflammatory demyelinating polyneuropathy
** Company says it does not plan to seek approval for the drug, batoclimab, for either of the two conditions but will focus on developing its other experimental drug IMVT-1402 for the same conditions
** Up to last close, Immunovant shares have fallen ~38% in the past 12 months
