            IMMUNOMEDICS ANNOUNCES SECOND QUARTER FISCAL 2007 RESULTS

    MORRIS PLAINS, N.J., Feb. 8 /PRNewswire-FirstCall/ -- Immunomedics, Inc.
(Nasdaq: IMMU), a biopharmaceutical company focused on developing monoclonal
antibodies to treat cancer and other serious diseases, today reported revenue of
$3.4 million and a net loss of $4.5 million, or $0.08 per share, for the second
quarter of fiscal year 2007, which ended December 31, 2006. This compares to
revenue of $0.5 million and a net loss of $8.8 million, or $0.16 per share, for
the same period last year. The increase in revenue for the three-month period
was primarily due to the recognition of deferred revenue of $2.7 million from
the May 9, 2006 Development, Collaboration and License Agreement between the
Company and UCB, S.A., and increased sales of LeukoScan(R) in Europe. The
increased revenue combined with lower operating and interest expenses and higher
interest income were the primary contributors to the improved net loss position
for the three-month period ended December 31, 2006.

    For the first half of fiscal year 2007, the Company reported revenue of $6.7
million and a net loss of $7.0 million, or $0.12 per share. This compares to
revenue of $0.9 million and a net loss of $17.4 million, or $0.32 per share, for
the same period last year. Recognition of portions of the initial cash payment
from UCB and increased LeukoScan(R) sales were also primarily responsible for
the improvement in revenue, as well as higher interest income and lower interest
and operational expenses for the decrease in net loss for the six-month period
ended December 31, 2006.

    During the second quarter of fiscal year 2007, the Company received $0.6
million in tax benefits through the New Jersey Technology Tax Certificate
Transfer Program. As of December 31, 2006, the Company had $31.4 million in cash
and marketable securities, excluding restricted securities.

    "We are pleased to report that the results for the second quarter were in
line with our expectations. We anticipate that our operations for fiscal 2007
will be at our forecasted levels, while bringing a new therapeutic into the
clinic," commented Gerard G. Gorman, Senior Vice President, Finance and Business
Development, and Chief Financial Officer. "Phase I/II clinical trials with our
humanized CD74 antibody have begun enrolling patients with multiple myeloma," he
added.

    As reported previously during the second quarter of fiscal year 2007, other
developments of note were as follows:

     -- The Company was awarded U.S. patent 7,151,164 covering methods for
        treating B-cell disorders using the Company's humanized monoclonal
        antibody that binds to the CD20 antigen present on B-lymphocytes for the
        treatment of B-cell lymphomas, leukemias and autoimmune diseases.

     -- The Company reported follow-up clinical results for hA20 in non-
        Hodgkin's lymphoma at the 48th Annual Meeting of American Society of
        Hematology.

     -- Also at the 48th Annual Meeting of American Society of Hematology, the
        Company presented new multivalent antibodies against the CD20 and CD22
        antigens present on normal and malignant B-lymphocytes.

     -- The Company presented at the 70th annual meeting of the American College
        of Rheumatology and the 41st annual meeting of the Association of
        Rheumatology Health Professionals results that showed that epratuzumab
        and rituximab have distinct mechanisms of action.

     -- The Company provided corporate overviews at the Lazard Capital Markets
        3rd Annual Life Sciences Conference, the Rodman & Renshaw 8th Annual
        Healthcare Conference, and the C.E. Unterberg, Towbin Life Sciences
        Conference.

     -- Mayo Clinic investigators, conducting a clinical trial in collaboration
        with the North Central Cancer Treatment Group of the National Institute
        of Health, published results in Cancer volume 107(12): pages 2826-32,
        2006, showing that adding epratuzumab to rituximab and combined
        cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy
        to treat patients with newly diagnosed diffuse large B-cell lymphoma
        produced promising results.



    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. The Company is conducting clinical trials with
hA20 in patients with non-Hodgkin's lymphoma, epratuzumab as a potential
therapeutic for patients with lymphoma and leukemia, (90)Y-epratuzumab for the
therapy of patients with lymphoma, (90)Y-hPAM4 for pancreas cancer therapy and
hCD74 as a therapy for patients with multiple myeloma. 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 (DNL) 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.
