            Lilly Discontinues Phase 3 Rheumatoid Arthritis Program            
                    for Tabalumab Based on Efficacy Results                    
                    Decision not based on safety concerns;                     
                  Phase 3 lupus program continues as planned                   

INDIANAPOLIS - Eli Lilly and Company (NYSE:LLY) announced today that it will
discontinue the Phase 3 rheumatoid arthritis (RA) program for tabalumab, an
anti-BAFF (B cell activating factor) monoclonal antibody, due to lack of
efficacy. The decision was not based on safety concerns. The tabalumab Phase 3
program for systemic lupus erythematosus, ILLUMINATE, is ongoing and will
continue as planned.

In December 2012, Lilly discontinued the Phase 3 RA registration study FLEX-M
for lack of treatment effect. FLEX-M was investigating tabalumab in patients
with moderate-to-severe RA who had an inadequate response to methotrexate

Based on FLEX-M findings, an interim futility analysis was conducted of the
FLEX-V study, which was investigating tabalumab for the treatment of patients
with moderate-to-severe RA who had an inadequate response to one or more tumor
necrosis factor (TNF) inhibitors.

Based on the outcomes of these two separate interim futility analyses, Lilly
has decided to discontinue development of tabalumab in the current RA program.
All ongoing Phase 2 and Phase 3 RA studies will be stopped.

"While we are obviously disappointed by these results in rheumatoid arthritis,
we continue to believe that tabalumab could have significant potential for
patients in other disease areas," said Eiry Roberts, M.D., vice president of
autoimmune product development at Lilly. "Autoimmune disorders are highly
individualized. We believe that targeting BAFF with a molecule such as
tabalumab may still represent an important advance for patients, and therefore
we will continue the ongoing Phase 3 tabalumab lupus program."

The decision to stop the current RA program for tabalumab is expected to result
in a first-quarter charge to research and development expense of approximately
$50 million. The company's previously issued financial guidance for 2013
remains unchanged.

About the FLEX-V Study

The FLEX-V study (study BCDV) is a Phase 3, multicenter, randomized,
double-blind, placebo-controlled study to evaluate the efficacy and safety of
tabalumab in patients with moderate-to-severe RA who had an inadequate response
to one or more TNF inhibitors.

About BAFF and Tabalumab 

BAFF (B cell activating factor) is a cytokine that promotes B cell survival,
proliferation and activation. In the presence of excess BAFF, B cells,
including autoreactive B cells, are not appropriately eliminated by the immune
system and may therefore contribute to the development of RA by producing
autoantibodies and proinflammatory cytokines and "helping" autoreactive T
cells. BAFF exists in both membrane-bound and soluble forms. Tabalumab is a
human immunoglobulin G subclass 4 (IgG4) monoclonal antibody (MAb) that
inhibits both membrane-bound and soluble B cell activating factor (BAFF).
Tabalumab is currently in Phase 3 development as a potential treatment for
systemic lupus erythematosus and in Phase 2 development in combination with
bortezomib for patients with previously-treated multiple myeloma.

About Lilly's Autoimmune Pipeline

Tabalumab is one of three potential new medicines in late-stage clinical
development for a variety of autoimmune conditions. The others are ixekizumab,
an anti-IL-17 monoclonal antibody, for psoriasis and psoriatic arthritis; and
baricitinib, a JAK1 and JAK2 inhibitor being developed in collaboration with
Incyte Corporation, for RA, psoriasis and diabetic nephropathy.

About Lilly's Pipeline

Lilly currently has a number of unique potential medicines in its Phase 3
clinical development pipeline, representing a variety of therapeutic areas
including diabetes (four), cancer (three), neuroscience (two), autoimmunity
(three) and cardiovascular (one). To learn more about the molecules in Lilly's
clinical development pipeline, please visit Lilly's interactive pipeline
