Vanda Pharmaceuticals, Inc. Completes Enrollment For Iloperidone And VEC-162 Phase III Trials Ahead Of Schedule

ROCKVILLE, Md., Aug. 30 /PRNewswire-FirstCall/ -- Vanda Pharmaceuticals Inc. , a biopharmaceutical company focused on the development and commercialization of clinical-stage product candidates for central nervous system disorders, today announced that it has completed enrollment in its iloperidone Phase III clinical trial for the treatment of schizophrenia and its VEC-162 Phase III clinical trial for the treatment of transient insomnia.

The iloperidone clinical trial is a randomized, double-blind, placebo- controlled Phase III trial in patients with schizophrenia. Vanda concluded enrollment in this trial with 604 patients as of August 29, 2006. The VEC-162 clinical trial is a randomized, double-blind, placebo-controlled transient insomnia trial in healthy volunteers. Vanda concluded enrollment in this trial with 412 patients as of August 21, 2006.

“We are very pleased to be able to announce the early completion of enrollment for both of our Phase III clinical trials,” said Mihael Polymeropoulos, M.D., President and CEO of Vanda. “In iloperidone, we look forward to providing schizophrenia patients and their physicians a compound with a differentiated safety profile and unique pharmacogenetic tools for identifying optimal iloperidone responders. We believe that VEC-162 offers a novel way of treating insomnia, in particular those patients with circadian rhythm disorders.”

As enrollment in both trials has significantly outpaced expectations, Vanda and its clinical research organizations are still in the process of allocating the resources required to manage and complete the site closeout and data management activities related to both of the Phase III trials. The Company expects to report top-line results for both the iloperidone and VEC- 162 trials in January of 2007. If the iloperidone trial is successful, Vanda expects to file a New Drug Application (NDA) with the Food and Drug Administration (FDA) by the end of 2007. The Company will need to conduct additional Phase III trials to receive FDA approval of VEC-162 for the treatment of insomnia.
