Boehringer Ingelheim to Initiate First Phase III Pivotal Study for New Oncology Compound BIBW 2992(i)

Ingelheim, Germany (ots/PRNewswire) -

- New Data on BIBW 2992(i), a Potent, Irreversible,
Second-Generation Oral Signal Transduction Inhibitor Provides
Glimpse of Next Chapter in Lung Cancer Care

- For Non-US Media

Boehringer Ingelheim announced today from the 12th World
Conference on Lung Cancer (WCLC) that the company plans to commence
Phase III pivotal trials in lung cancer with BIBW 2992(i), its novel,
second generation, potent, irreversibly binding, dual inhibitor of
EGFR and HER2 and thereby further demonstrated its commitment to
discovery and development of novel compounds in oncology. Details of
this important stage in the clinical development of BIBW 2992(i) are
currently being finalised with regulatory authorities in both the USA
(FDA) and Europe (EMEA).

This significant milestone represents an important advance for
Boehringer Ingelheim's evolving oncology portfolio and coincides with
the presentation of key data at WCLC for BIBW 2992(i).

In a phase I study(1) by Spicer et al, evaluating the activity of
BIBW 2992(i) in patients with various solid tumours, encouraging
results were obtained in patients with non-small cell lung cancer
(NSCLC) with mutated EGFR. Initial signs of clinical efficacy were
observed with durable partial responses seen in 20% of patients with
NSCLC (two female and one male) with at least two of them having
deletions in EGFR exon 19 - a genetic mutation known to be more
common in females, never smokers and in patients with adenocarcinoma.
In addition, BIBW 2992(i) was found to be well tolerated at an oral
dose of 50mg daily.

Study investigator, Dr. James Spicer, Senior Lecturer and
Consultant in Medical Oncology at King's College School of Medicine,
Guy's Hospital, London, U.K., commented on the findings: "More
effective treatments for lung cancer, with fewer side effects, are
badly needed. Novel, irreversible EGFR inhibitors like BIBW 2992(i)
provide us with a glimpse of the next chapter in the evolution of
lung cancer care, as they may bridge significant gaps in existing
therapy, for example, addressing issues of resistance to treatment."

"We also need to recognise that not all lung cancer is the same,
and an era of personalised prescribing in oncology is not far away.
In particular, patients most likely to benefit from drugs designed to
hit EGFR and related targets are female, light or never smokers, or
those from East Asian populations, a group who often have
adenocarcinoma tumours with mutated EGFR," he added.

Currently in phase II development, BIBW 2992(i) holds promise for
activity against tumours resistant to first-generation inhibitors,
due to its unique, irreversible dual inhibition of EGFR and
HER2(2),(3), two oncogenes associated with poor prognosis and
advanced stage cancer. In studies to date(4), BIBW 2992(i) has been
shown to have effect particularly in lung cancer patients with
specific genetic mutations, reinforcing the need for further research
in this field.

Phase I and Phase II study results from three trials in advanced
NSCLC patients were also presented at WCLC for the triple angiokinase
inhibitor BIBF 1120(i), another of Boehringer Ingelheim's key
oncology compounds, simultaneously acting on vascular endothelial
growth factor receptor (VEGFR), platelet-derived growth factor
receptor (PDGFR) and fibroblast growth factor receptor (FGFR).(5)

In both Phase I studies(6),(7), the dose for BIBF 1120(i) in
combination with pemetrexed or carboplatin/paclitaxel has been
determined to be 200mg twice daily. In all three trials, BIBF 1120(i)
has been shown to be safe and well tolerated. Furthermore,
encouraging signs of efficacy have been observed in the Phase II
trial by Reck et al(8) with a considerably high rate of disease
stabilisation (48%) for all patients.

These data, coupled with the company's commitment to enter its
first pivotal Phase III trial in oncology, mark significant progress
for Boehringer Ingelheim's evolving oncology pipeline, which
currently spans three key areas: signal transduction inhibition,
angiokinase inhibition and cell cycle kinase inhibition.

Dr. Andreas Barner, Vice Chairman of the Board of Managing
Directors at Boehringer Ingelheim, said of the company's emergence
into the field of oncology "We are using advances and breakthrough
science to actively develop targeted therapies - biologicals and
small molecules - in areas of unmet medical need, with a particular
interest in lung cancer. With the progress made we have again
underlined our commitment to discovering and developing innovative
cancer treatments that provide high therapeutic value for patients,
physicians and healthcare providers."

BIBW 2992(i) and BIBF 1120(i) are the most advanced compounds in
the Boehringer Ingelheim oncology pipeline.

About the International Association for the Study of Lung Cancer

Founded in 1972, the International Association for the Study of
Lung Cancer (IASLC) is an international organization of 2,000 lung
cancer specialists, spanning 53 countries. IASLC members work towards
developing and promoting the study of etiology, epidemiology,
prevention, diagnosis, treatment and all other aspects of lung
cancer. IASLC's mission is to enhance the understanding and education
of lung cancer to scientists, members of the medical community and
the public. In addition to the biannual meeting, the IASLC publishes
the Journal of Thoracic Oncology, a prized resource for medical
specialists and scientists who focus on the detection, prevention,
diagnosis and treatment of lung cancer.
