There isn't much literature on this, so my best guess might have to suffice.
OCD is on the anxiety spectrum of disorders. Vortioxetine is ineffective for GAD and therefore may not help remediate OCD symptoms.
Upon doing more research, I found evidence that both supports Vortioxetine as a treatment for GAD, and evidence that claims it is equivalent to placebo. Talk about confusing!
In regards to OCD, Reference 5 states that their evidence suggests newer "agents (ADs) should be tested more comprehensively.". It doesn't state that any of the newer antidepressants (which includes Vortioxetine) were ineffective. Based on Vortioxetine's mixed results for GAD, and the very vague and tentative for OCD, Vortioxetine is possibly an effective treatment for OCD.
