       VANDA PHARMACEUTICALS REPORTS SECOND QUARTER 2006 FINANCIAL RESULTS

    COMPANY'S PHASE III TRIAL ENROLLMENT FOR ILOPERIDONE IS NEAR COMPLETION;
           COMPANY'S PHASE III TRIAL FOR VEC-162 IS AHEAD OF SCHEDULE

     ROCKVILLE, Md., Aug. 3 /PRNewswire-FirstCall/ -- Vanda Pharmaceuticals Inc.
(Nasdaq: VNDA), a biopharmaceutical company focused on the development and
commercialization of clinical-stage product candidates for central nervous
system disorders, today announced financial and operational results for the
second quarter ended June 30, 2006.

     Vanda reported research and development (R&D) expenses in the second
quarter of $19.1 million, compared to first quarter 2006 R&D expenses of $15.5
million and second quarter 2005 R&D expenses of $3.7 million. Total expenses for
the second quarter of 2006 were $22.1 million, compared to $18.4 million in the
first quarter of 2006 and $5.5 million in the second quarter of 2005. The
increase in expenses is primarily attributable to the combined costs of
administering the Company's current Phase III trial for its product candidate
iloperidone and the Company's current Phase III trial for its product candidate
VEC-162.

     Net loss applicable to common stockholders was $21.4 million for the second
quarter of 2006, compared to a net loss of $18.1 million in the first quarter of
2006 and a net loss of $5.5 million in the second quarter of 2005. As of June
30, 2006, Vanda's cash, cash equivalents, and short-term investments totaled
$60.2 million.

     "We are pleased to see that our two Phase III clinical trails continue to
enroll ahead of schedule and move closer to completion," stated Mihael
Polymeropoulos, M.D., President and CEO of Vanda. "Looking ahead, we are excited
and optimistic about reporting the results for both of these trials as early as
the first quarter of 2007, and if successful, our anticipated NDA filing for
iloperidone by the end of 2007."

     OPERATIONAL HIGHLIGHTS

     Iloperidone Phase III Trial

     Vanda's ongoing Phase III clinical trial to evaluate its product candidate
iloperidone for the treatment of patients with schizophrenia is significantly
ahead of schedule and is nearing the completion of achieving its enrollment
target. The trial is a randomized, double-blind, placebo-controlled Phase III
trial of approximately 600 patients.

     The study began in November 2005, and reached an enrollment of 567 patients
as of July 31, 2006. Vanda expects to report top-line results early in the first
quarter of 2007. If successful, Vanda expects to file a New Drug Application
(NDA) with the Food and Drug Administration (FDA) for iloperidone by the end of
2007.

     VEC-162 Phase III Trial

     In February 2006, the Company initiated a Phase III clinical trial to
evaluate the safety and efficacy of its product candidate VEC-162 for the
treatment of insomnia. The trial is a randomized, double-blind, placebo-
controlled transient insomnia trial in which we expect to enroll approximately
400 healthy volunteers at up to 20 investigator sites in the U.S. The trial will
measure sleep efficiency and time to fall asleep, as well as next-day
performance and mood.

     Enrollment for the trial is ahead of schedule and reached an enrollment of
308 patients as of July 31, 2006. Vanda expects to report the top-line results
in the first quarter of 2007. The Company will need to conduct additional Phase
III trials to receive FDA approval of VEC-162 for the treatment of insomnia.



     FINANCIAL DETAILS

     *    Operating Expenses. Second quarter research and development expenses,
          primarily consisting of salaries, stock-based compensation, and
          related expenses for personnel and capital resources used in the
          Company's clinical trials and research initiatives, were $19.1
          million, up from $15.5 million in the previous quarter and up from
          $3.7 million in the second quarter of 2005. The increase in R&D
          expenses in the second quarter relative to the first quarter of 2006
          was primarily due to an increase in clinical trial expenses related to
          the Company's two ongoing Phase III clinical trials.

          General and administrative (G&A) expenses totaled $3.0 million in the
          second quarter of 2006, up from $2.9 million in the first quarter of
          2006, and up from $1.9 million in the second quarter of 2005. The
          increase in G&A expenses in the second quarter of 2006 relative to the
          first quarter of 2006 was primarily due to increased insurance expense
          and professional fees.

          Stock-based compensation recorded in the second quarter of 2006 was
          $1.5 million for employees under SFAS 123(R). Of the total $1.5
          million, $0.1 million was recorded in R&D expenses and $1.4 million
          was recorded in G&A expenses. In the first quarter of 2006 and the
          second quarter of 2005, total stock-based compensation was $1.5
          million and $1.4 million, respectively.

     *    Net loss applicable to common stockholders for the second quarter of
          2006 was $21.4 million. This compares to a net loss of $18.1 million
          in the first quarter of 2006 and $5.5 million in the second quarter of
          2005.

     *    Cash and marketable securities increased by $40.1 million during the
          second quarter. Changes were primarily composed of $21.4 million of
          operating losses and $0.5 million in fixed asset additions and other
          items, offset by net cash proceeds of $53.3 million from the issuance
          of common stock in the Company's initial public offering, increases in
          accrued R&D expenses and accounts payable of $5.9 million, decreases
          in prepaid expenses and deposits of $1.1 million and $1.6 million of
          non- cash depreciation, amortization, and stock-based compensation
          expenses.

     *    The balance sheet at June 30, 2006 reflected $60.2 million of
          unrestricted cash, cash equivalents and marketable securities,
          compared to $20.1 million as of March 31, 2006, and $31.2 million as
          of December 31, 2005.

     FINANCIAL GUIDANCE

     As previously discussed last quarter full year 2006 financial results are
expected to show total cash used from the Company's operations to be
approximately $60 million to $65 million. Total cash balance at December 31,
2006 is expected to be in the range of $20 million to $25 million, without
taking into account the receipt of any proceeds from collaborations or
partnerships that the Company may enter into in 2006. Vanda anticipates that its
current funds will be sufficient to complete and report the results from its
ongoing iloperidone and VEC-162 Phase III clinical trials that are expected to
be completed in the first quarter of 2007, and to continue additional
development and clinical activities for its product candidates.

     Net loss for the year is expected to be between $70 million to $75 million,
or approximately $4.38 to $4.69 per diluted common share. Non-cash charges for
2006, consisting primarily of stock-based compensation expenses and depreciation
and amortization, are expected to be approximately $8 million. Per share figures
were computed on a weighted average basis of 15,986,501 common shares
outstanding at the end of the year.
