Pharmaceutical compositions and methods for fabrication of solid masses comprising TNF-inhibiting antibodies
Embodiments of the invention provide shaped masses comprising one or more drugs such as proteins or polypeptides and methods for forming such shaped masses. One embodiment provides a shaped mass comprising a drug such as a protein or polypeptide having a biological activity in the body of a mammal. The shaped mass is formed by compression of a precursor material comprising the drug wherein an amount of biologically active drug in the mass is a preserved above a minimum level. Drugs which may be incorporated into the shaped mass may include one or more glucose regulating proteins such as insulin, incretins; and immunoglobulins such as TNF-inhibiting antibodies or interleukin neutralizing antibodies. Embodiments of the shaped mass may be incorporated into a tissue penetrating member which is inserted into the intestinal wall allowing for the oral delivery of proteins and peptides which would otherwise be degraded in the intestinal tract.
