Exhibit 99.1

MORRIS PLAINS, N.J., Sept. 6 /PRNewswire-FirstCall/ -- Immunomedics, Inc.
(Nasdaq: IMMU), a leading biopharmaceutical company focused on developing
monoclonal antibodies, announced today that it has received a letter from The
Nasdaq Stock Market notifying the Company that the Nasdaq Listing and
Qualification Panel has ruled in favor of the Company. As a result, the Company
will remain listed on the Nasdaq National Market.

"We are pleased with the positive ruling from the Nasdaq panel. Our stock has
been listed on The Nasdaq Stock Market for over 20 years and we look forward to
continue working with Nasdaq," commented Cynthia L. Sullivan, President and
Chief Executive Officer of the Company.

The letter from Nasdaq is related to the Nasdaq Listing Qualification Staff's
decision on June 10, 2005, to delist the Company. The Nasdaq listing staff
indicated that the Company's financing in April, 2005, did not comply with one
of the Nasdaq Marketplace Rules, which provides that stockholders must approve
an issuance of securities equal to 20% of the common stock for less than the
greater of book or market value of the stock outstanding.

The Company appeared before the Nasdaq Listing and Qualification Panel on July
21, 2005, to appeal the Nasdaq listing qualification staff's June 10th decision.
On August 19, 2005, a significant majority of the Company's stockholders
approved the two proposals presented at a special meeting thereby authorizing
the Company to file an amendment to the Company's certificate of incorporation
to increase the authorized common stock by 40 million shares, and issue common
stock upon the conversion of the Company's outstanding 5% Senior Convertible
Notes due 2008 and exercise of related Common Stock Warrants in connection with
the April 29, 2005 financing. As with all decisions made by the Nasdaq Listing
and Qualifications Panel, the Company is aware that the Nasdaq Listing and
Hearing Review Council may, on its own motion, determine to review any panel
decision within 45 calendar days after the issuance of the written decision. If
the Listing Council determines to review the decision, it may affirm, modify,
reverse, dismiss, or remand the decision to the Panel. The Company will be
immediately notified if the Listing Council determines that this matter will be
called for review.

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. Our lead product candidate, epratuzumab, is currently in two pivotal
Phase III trials for the treatment of patients with moderate and severe lupus
(ALLEVIATE A and B). At present, there is no cure for lupus and no new lupus
treatment drug has been approved in the U.S. in the last 40 years. We believe
that our portfolio of intellectual property, which includes approximately 90
patents issued in the United States, and more than 250 other issued patents
worldwide, protects our product candidates and technologies. Visit our web site
