            IMMUNOMEDICS ANNOUNCES FIRST QUARTER FISCAL 2007 RESULTS

    MORRIS PLAINS, N.J., Nov. 6 /PRNewswire-FirstCall/ -- Immunomedics, Inc.
(Nasdaq: IMMU), a leading biopharmaceutical company focused on developing
monoclonal antibody-based products, today reported revenues of $3.3 million
and a net loss of $2.5 million, or $0.04 per share, for the first quarter of
fiscal year 2007, which ended September 30, 2006.  This compares to revenues
of $0.4 million and a net loss of $8.5 million, or $0.16 per share, for the
same period last year.

    The increase in revenues for the first quarter was primarily due to the
recognition of $2.7 million of the $38 million initial payment received from
UCB, S.A., for the licensing of epratuzumab for all autoimmune diseases
worldwide, and increased LeukoScan(R) sales in Europe. The operating expenses
for the first quarter improved due to lower R&D expenses resulting from the
transfer of the ALLEVIATE trials to UCB as part of the May 9, 2006 agreement.
Lower interest expense and higher interest income have also contributed to the
lower net loss for the first quarter. At September 30, 2006, the Company had
$35.0 million in cash and marketable securities, excluding restricted
securities.

    "Our burn rate improved this quarter as a result of our licensing agreement
with UCB. We are committed to bringing new antibodies into the clinic that have
the shortest path to commercial success in markets with unmet medical needs.
Consequently, we expect our R&D expenses to moderately increase in future
quarters as these new antibodies enter the clinic," commented Gerard G. Gorman,
Senior Vice President, Finance and Business Development, and Chief Financial
Officer. "An example of such product development is our humanized CD74 antibody,
which will begin clinical trials in patients with multiple myeloma in the near
future," he added.

    "We are working closely with UCB to expedite efforts to remove the clinical
hold status instituted by the FDA and other regulatory agencies, which would
minimize any further delay in making epratuzumab available to patients," said
Cynthia L. Sullivan, President and Chief Executive Officer of the Company. "We
share UCB's enthusiasm in the continued development of epratuzumab in autoimmune
disease indications, and we look forward to resuming dosing patients with lupus
in the near future," she further remarked.

    About Immunomedics

    Immunomedics is a New Jersey-based biopharmaceutical company focused on the
development of monoclonal, antibody-based products for the targeted treatment of
cancer, autoimmune and other serious diseases. We have developed a number of
advanced proprietary technologies that allow us to create humanized antibodies
that can be used either alone in unlabeled or "naked" form, or conjugated with
radioactive isotopes, chemotherapeutics or toxins, in each case to create highly
targeted agents. Using these technologies, we have built a pipeline of
therapeutic product candidates that utilize several different mechanisms of
action. We have recently licensed our lead product candidate, epratuzumab, to
UCB, S.A. for the treatment of all autoimmune disease indications worldwide. We
have retained the rights for epratuzumab in oncology indications for which UCB
has been granted a buy-in option. UCB has development, manufacture and
commercialization rights, and is responsible for all clinical trials evaluating
epratuzumab for the treatment of patients with moderate and severe lupus. At
present, there is no cure for lupus and no new lupus drug has been approved in
the U.S. in the last 40 years. We believe that our portfolio of intellectual
property, which includes approximately 108 patents issued in the United States,
and more than 250 other issued patents worldwide, protects our product
candidates and technologies. We also have a majority ownership in IBC
Pharmaceuticals, Inc., which is developing a novel dock and lock methodology,
and a new method of delivering imaging and therapeutic agents selectively to
disease, especially different solid cancers (colorectal, lung, pancreas, etc.),
by proprietary, antibody-based, pretargeting methods. Visit our web site at
