                   DOV Pharmaceutical, Inc. Announces Amended
                  Agreement with Merck & Co., Inc. on its Novel
                                 Antidepressants


Hackensack, NJ, August 8, 2005. DOV Pharmaceutical, Inc (NASDAQ: DOVP) announced
that DOV and Merck & Co., Inc. have amended their 2004 license agreement
covering the clinical development activities of DOV 21,947 and DOV 216,303.
Under the amendment certain development contemplated by the license agreement
for DOV 21,947 will initially be undertaken by DOV. In addition, the amendment
provides for the possible future expansion of the collaboration with Merck to
include an additional triple reuptake inhibitor from DOV's preclinical pipeline
if such compound is selected after certain testing has been completed by Merck.
The amendment follows review of data from preclinical studies in models of
depression and a pilot phase I biomarker study in normal volunteers. The further
clinical testing intended by this amendment will permit the parties to collect
and assess additional clinical data to better understand the properties and
market potential of DOV 21,947.

The testing to be done by DOV comprises a phase 1b clinical trial in normal
volunteers and two phase II clinical trials in depressed patients for DOV
21,947, as well as further research and development intended to characterize the
compound.

If the phase II studies for DOV 21,947 are successful, DOV will be reimbursed by
Merck for pre-agreed expenses and will receive a success premium. Subsequently,
DOV could receive payment for achievement of certain clinical development and
regulatory milestones pursuant to the existing agreement. Merck may additionally
select a compound from DOV's preclinical pipeline. Both parties retain certain
termination rights.

This amendment retains intact the milestones, royalties and business terms
originally established in the license agreement. It furthermore retains DOV's
co-promote rights.

Dr. Leslie Hudson, DOV's new president and CEO, commented, "We believe that the
continued collaboration contemplated by this amendment is indicative of our
productive and evolving relationship with Merck. I am pleased that these new
studies will be undertaken with a view to understanding the early findings and
evaluating the clinical utility of triple reuptake inhibitors. Results of a
study on DOV 216,303 in patients with major depressive disorder with the SSRI
citalopram as a comparator were suggestive of efficacy comparable to the SSRI.
The study was started by DOV prior to the license to Merck. DOV 21,947 is the
plus isomer of the racemate DOV 216,303 and therefore structurally related. DOV,
confident of the worth of its development pipeline, looks forward to a solid,
continuing relationship with Merck."

including statements regarding our expectations with respect to the progress of
and level of expenses for our clinical trial programs. You can also identify
forward-looking statements by the following words: may, will, should, expect,
intend, plan, anticipate, believe, estimate, predict, potential, continue or the
negative of these terms or other comparable terminology. We caution you that
forward-looking statements are inherently uncertain and are simply point-in-time
estimates based on a combination of facts and factors currently known by us
about which we cannot be certain. Actual results or events will surely differ
and may differ materially from our forward-looking statements as a result of
many factors, some of which we may not be able to predict or may not be within
our control. Such factors may also materially adversely affect our ability to
achieve our objectives and to successfully develop and commercialize our product
candidates, including our ability to:

      o     demonstrate the safety and efficacy of product candidates at each
            stage of development;

      o     meet our development schedule for our product candidates, including
            with respect to clinical trial initiation, enrollment and
            completion;

      o     meet applicable regulatory standards and receive required regulatory
            approvals on our anticipated time schedule or at all;

      o     meet obligations and required milestones under our license and other

candidates may not exhibit the expected therapeutic results, (iii) we or the FDA
may suspend one or more of our clinical trials, (iv) patient recruitment may be
slower than expected or patients may drop out of our clinical trials, (v)
regulatory approval for our product candidates may not be received or may be
