TOKYO,ROCKVILLE, Md. and EPALINGES, Switzerland, Jan. 6, 2014 /PRNewswire/ --
Astellas Pharma Inc. (Astellas) and ClearPath Development Company (ClearPath)
announced today a strategic partnership to form a portfolio of development
companies focused on vaccines targeting infectious diseases. The partnership
was established to support Astellas' goal of building a global vaccine
franchise and launched its first company, RSV Corporation (RSVC), in December
2013. Astellas will fund RSVC's development of a virosome vaccine technology,
licensed from Mymetics Corporation (Mymetics - OTC BB: MYMX), for respiratory
syncytial virus (RSV) through completion of a Phase 2b human proof-of-concept
study. Based on the strategic partnership, Astellas received exclusive rights
to acquire RSVC as well as further develop and commercialize the vaccine
product.

"This partnership highlights our commitment to build a global vaccine business
and represents a highly efficient model for bringing innovative vaccines to
market. It is also a unique opportunity for Astellas to utilize external
cutting edge science and technology to enhance our ability to generate
innovative drugs, as part of the "Reshaping Research Framework" program
announced in May, 2013," said Kenji Yasukawa, Senior Vice President and Chief
Strategy Officer, Astellas.

RSV is a respiratory pathogen which infects patients of all ages. The
infection can be especially severe in infants and older adults with chronic
pulmonary or cardiovascular disease. Each year the virus infects 64 million
people and is responsible for 160,000 deaths worldwide. Currently, there is
no vaccine available for this virus.

"Together we are harnessing our collective resources to accelerate development
of this promising, early stage asset and will replicate this scalable, outcome
driven model across future portfolio companies," said Chuck Finn, PhD,
Chairman, ClearPath Development Company.

Mymetics will collaborate with RSVC on the development of the vaccine, with
Toon Stegmann PhD, CSO of Mymetics, remaining engaged on pre-clinical
activities including nonclinical evaluation, formulation development, and
manufacturing. RSVC's development team is led by George Siber, MD, a
recognized vaccine expert with more than 35 years experience. From 1996 to
2007, Dr. Siber was Executive Vice President and Chief Scientific Officer of
Wyeth Vaccines Research where he oversaw the approval and marketing of six
childhood vaccines including Prevnar, Meningitec, Rotashield and FluMist.

"The financial backing and commercial experience of Astellas combined with
ClearPath's development expertise and our continued program involvement are
unique factors which all work to increase the likelihood of success," said
Ronald Kempers, CEO, Mymetics. "We anticipate RSV will be the first of many
vaccine constructs that can be generated from our proprietary 2^nd generation
virosome platform."

For its technology for RSV, Mymetics could receive upfront and post
proof-of-concept milestone payments up to $82 million, as well as double
digits royalties and other payments.

The virosome vaccine consists of membrane nanoparticles containing the native
key viral surface proteins that are targets of the immune system, but lack the
genetic material required to cause infection. In pre-clinical testing, it
generatedpowerful immune responses and strong protection against RSV.
Virosome-based vaccines have a proven track record of safety and efficacy for
the prevention of other infections including influenza.
