ITEM 8.01.  OTHER EVENT.

         Immunomedics, Inc., a Delaware corporation, reported that licensing
partner, UCB, SA, has temporarily suspended the clinical trials of epratuzumab
in patients with systemic lupus erythematosus. The companies advised their
investigators that this is not being done because of any adverse reactions in
patients, but because of end-stage manufacturing observations by UCB during a
recent audit. These observations, related to the filling processes during final
product manufacturing, in UCB's opinion might result in a lack of consistent
assurance of sterility in the final dosage form. This is a precautionary
measure, taken voluntarily and pro-actively by UCB. No reports of clinical
safety issues that suggest an association with these observations have been
identified. In response to the voluntary suspension, FDA and certain other
regulatory authorities have instituted a clinical hold status on the trials. The
companies are working together to expedite their efforts to remove the clinical
hold status and minimize any delay in making epratuzumab available to patients.
Immunomedics does not believe this suspension will have a material effect on the
trials.

         Importantly, Immunomedics has reported to UCB that it has not
encountered any product sterility failures for any batches that have been
released for clinical use nor has it encountered any media fill failures.
Furthermore, to date there have been no clinical safety reports associated with
these observations in the more than 600 patients who have received epratuzumab
therapy. UCB and Immunomedics are diligently addressing the process issues and
UCB will propose a strategy to FDA and other authorities to remove the clinical
hold status and resume dosing patients in the near future. The companies are
particularly concerned that patients who may have already benefited from
epratuzumab in the lupus clinical trials are able to resume treatment as soon as
possible.

         UCB has informed Immunomedics they remain fully committed to the
further development of epratuzumab in lupus and potentially other autoimmune
disease indications, while applying the highest quality, safety and ethical
standards in clinical development.
