Platform approaches have been implemented for monoclonal antibodies and
Fc fusion proteins; however, biochemical differences in non-mAb molecules
of the same class warrant the need for some development efforts (Ɣ).
KBI’s approach for non-mAb emerging therapies is to leverage our
experience to identify and study those parameters that most impact process
robustness and product quality attributes, and to use platform conditions for
the remaining process parameters

Challenging Emerging Therapies: HIV envelop proteins
A vaccine strategy was devised using gp120
envelop proteins to induce a broadly
Neutralizing antibody CH103 in healthy
individuals
The gp120 envelop proteins are complex
molecules requiring advanced analytics
These molecules are also hard to express & purity
H.X. Liao et al. Nature 496: 469; 2013

Parameters shaded in gray are defined across
molecules. Parameters shaded in yellow
require molecule specific optimization
Load & elution conditions for three of the unit
operations require molecule specific definition
given the heterogeneity of this class of
molecules
Env antigens structurally sensitive to
hydrophobic surfaces, hence HIC not
employed
