should be TRUE i.e.

(reply :content (SUCCESS :is-target TRUE) :receiver BA :in-reply-to DTDA-QUERY-328).

It is currently FALSE for some reason.

Okay, so this is technically not an error but perhaps the behavior defined here should be changed. Currently is-drug-target only looks at nominal targets and not all targets listed, and TGFBR1 isn't the nominal target of Tozasertib according to the database.
