Eli Lilly and Company and Bristol-Myers Squibb Company  announced today that they have stopped
enrollment in one of their two global Phase III studies evaluating necitumumab,
an investigational anti-cancer agent, as a first-line treatment for advanced
non-small cell lung cancer (NSCLC).

The randomized, multi-center, open-label Phase III trial,
named INSPIRE, is evaluating the addition of necitumumab, a fully-human IgG1 monoclonal
antibody, to a combination of ALIMTA (pemetrexed for injection) and cisplatin
compared to a regimen of ALIMTA and cisplatin, as a first-line treatment for
patients with advanced nonsquamous NSCLC. No new safety issues were seen in the
control arm with Alimta and cisplatin.

The decision to stop enrollment followed an independent Data
Monitoring Committee (DMC) recommendation that no new or recently enrolled
patients continue treatment in the trial because of safety concerns related to
thromboembolism (blood clots) in the experimental arm of the study. The DMC
also noted that patients who have already received two or more cycles of
necitumumab appear to have a lower ongoing risk for these safety concerns.
These patients may choose to remain on the trial, after being informed of the
additional potential risks. Investigators will continue to assess patients
after two cycles to determine if there is a potential benefit from treatment.

As noted earlier, necitumumab continues to be studied in a
Phase III trial named SQUIRE. This study is evaluating necitumumab as a potential
treatment for a different type of lung cancer called squamous non-small cell
lung cancer in combination with GEMZAR (gemcitabine HCl for injection) and
cisplatin. The same independent DMC recommended that this trial continue
because no safety concerns have been observed.

“Patient safety is paramount. While stopping enrollment
in one of the two Phase III trials is disappointing, the SQUIRE Phase III study
of necitumumab in lung cancer continues,” said Richard Gaynor, M.D., vice president,
oncology product development and medical affairs for Lilly.

“Lilly remains committed to developing new medicines
that can help treat this devastating disease.” Lilly has contacted all
trial investigators to provide detailed information on how to manage
individuals enrolled in the trial, and has notified all pertinent regulatory
agencies of this decision.

Necitumumab is being developed in a partnership between
Lilly and Bristol-Myers Squibb. The two companies share development costs and any
potential commercialization within the U.S.,
Canada and Japan, while Lilly has exclusive
commercialization rights in all other countries.
