November 2011. There are ten clinical trials of MEK162 ongoing, including two Phase 2 trials, three
Phase 1b trials in combination with different PI3 kinase inhibitors and two Phase 1b trials in combination
with different RAF inhibitors. Promising data on MEK162 in an ongoing Phase 2 trial of patients with
BRAF and NRAS mutated advanced melanoma were presented at the 2012 ASCO Annual Meeting. In
this trial, MEK162 showed clinical activity and good tolerability in patients with BRAF or NRAS melanoma.
This is the first targeted therapy to show activity in patients with NRAS mutated melanoma. The ongoing
Phase 2 open-label trial is being conducted by Novartis and continues to enroll patients. As of February
2012, eight of the 35 patients with BRAF mutations evaluable for response had partial responses,
including two confirmed partial responses, and 13 patients demonstrated stable disease. The disease
control rate was 60 percent among these patients. Of the 28 patients with NRAS mutations who were
evaluable for response, six had partial responses, including three confirmed partial responses, and 13
patients had stable disease. The disease control rate was 68 percent among these patients. The median
progression-free survival was 3.55 months [95% CI 2.00 - 3.81 months] for patients with BRAF mutation
and 3.65 months [95% CI 2.53 - 5.39 months] for patients with NRAS mutations.

inhibitors of the Hepatitis C Virus, or HCV, NS3/4A protease. As a result of drug discovery activities under
this collaboration, scientists at Array and InterMune jointly discovered danoprevir. In October 2010 Roche
acquired danoprevir from InterMune for $175 million. InterMune thereafter ceased all further development
efforts under the collaboration. Under the terms of Array's collaboration agreement with InterMune,
InterMune has an obligation to make milestone payments to us based on the selection and progress of
in milestone payments and have the potential to earn an additional $9.0 million if all clinical and
commercialization milestones for danoprevir are achieved under the agreement.
through the purchase of danoprevir. The hepatitis market is evolving and, to meet the different needs of
people infected with HCV, future treatment options are likely to include interferon-free, as well as
interferon-containing triple- and quadruple-combination therapy regimens. Roche has several oral,
direct-acting antiviral agents in late-stage development for HCV, including danoprevir, which is currently
in a Phase 2 clinical trial. Roche is conducting two Phase 2 trials, MATTERHORN and INFORM-SVR, of
danoprevir in combination with mericitabine, a nucleoside polymerase inhibitor being developed by
Roche, with and without interferon, or IFN, in two Phase 2 trials. Roche also conducted a Phase 2 trial,
DAUPHINE, of danoprevir in IFN-containing regimens for HCV.
the Liver Congress from the DAUPHINE and INFORM-SVR studies. The DAUPHINE trial showed high
sustained viral response (SVR) rates, maintaining undetectable viral levels 12 weeks after stopping
treatment, and good tolerability with danoprevir in IFN-containing regimens for HCV. In this trial, up to
93% of genotype 1 and 100% of genotype 4 patients achieved SVR12 with ritonavir-boosted danoprevir,
IFN and ribavirin, considered a clinical cure. In the INFORM-SVR Phase 2 trial, 71% of genotype 1b
patients achieved SVR12 with boosted danoprevir, mericitabine and ribavirin as part of an IFN-free
regimen. Results from a third MATTERHORN Phase 2 trial evaluating danoprevir in combination with
mericitabine are currently expected during the second half of 2012.
HER2 / EGFR inhibitor, ASLAN001 (ARRY-543), which is currently in Phase 2 development in patients
with gastric cancer in Asia. Under the agreement, ASLAN is funding and developing ASLAN001 through
clinical proof of concept. Upon achievement of proof of concept, ASLAN will identify a global partner for
Phase 3 development and commercialization. Array will share a significant portion of the proceeds of
such partnering transaction.
