Cell Line Development, Manufacturing Services and License Agreement, effective as of February 9, 2021, by and between ValenzaBio, Inc. and ProBioGen, Inc

ProBioGen is a technology and service provider, specialized in development and production of recombinant therapeutic proteins for 3rd parties. ProBioGen is known for high quality, royalty-free services, from stable high producer cell line generation up to GMP-manufacturing of clinical trials supplies;

ProBioGen AG (“ProBioGen”) developed its GlymaxX^® ADCC enhancement technology to genetically engineer antibody producer cell lines. This technology is mainly applicable for antibody therapies in cancer indications, in which ADCC plays a major role. The technology is based on stable expression of [***]. This causes the secretion of literally completely [***] with greatly increased [***].

GlymaxX^® can be used to [***]

ValenzaBio has in-licensed a cell line expressing a therapeutic antibody (VB119). VB119 is [***]. The current producer cell line is [***]. This cell line has reduced expression of [***], leading to [***];

ValenzaBio seeks the opportunity to switch the expression system and to generate a new [***], which may result in a different [***] Product. The newly expressed VB119 is intended to be similar to the existing investigational candidate. Such a development program may thus benefit from ProBioGen’s GlymaxX^® ADCC enhancement technology.

ValenzaBio asked ProBioGen to provide a proposal, describing the process, costs and time lines for [***] applying the GlymaxX^® ADCC enhancement technology and to further provide the license terms of the technology;

Waiver. A waiver of any provision of this Agreement will only be valid if provided in writing and will only be applicable to the specific incident and occurrence so waived.
