Abstract
The present invention is directed to an antibody composition for use in treating proctitis, wherein the antibody composition comprises intact blood-derived polyclonal antibodies that bind to a human tumour necrosis factor α (TNFα). The invention also relates to associated uses, methods, solid compositions, and liquid compositions using/comprising the same.
Claims33
An antibody composition for use in treating proctitis, wherein the antibody composition comprises intact blood-derived polyclonal antibodies that bind to a human tumour necrosis factor α (TNFα).
Use of an antibody in the manufacture of a medicament for treating proctitis, wherein the antibody is an intact blood-derived polyclonal antibody that binds to a human tumour necrosis factor α (TNFα).
A method of treating proctitis, the method comprising administering an antibody composition to a subject, wherein the antibody composition comprises intact blood-derived polyclonal antibodies that bind to a human tumour necrosis factor α (TNFα).
The antibody composition for use, use or method according to any one of the preceding claims, wherein at least 5% of the total antibodies present in the composition bind to TNFα.
The antibody composition for use, use or method according to any one of the preceding claims, wherein at least 10% of the total antibodies present in the composition bind to TNFα.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the antibody composition or medicament is formulated as a solid, preferably as a suppository.
The antibody composition for use, use or method according to any one of the preceding claims, wherein a single dose comprises 1000 mg or less of the antibodies (e.g. 500 mg or less).
The antibody composition for use, use or method according to any one of the preceding claims, wherein a single dose comprises 250 mg or less of the antibodies.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the antibody composition is administered to a subject at least once daily.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the antibody composition is administered to a subject at least twice daily, preferably three times daily.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the antibody composition is administered rectally.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the proctitis is idiopathic proctitis.
The antibody composition for use, use or method according to any one of the preceding claims, wherein the subject also has a sexually transmitted disease, coeliac disease or a combination thereof.
The antibody composition for use, use or method according to any one of the preceding claims, wherein a subject treated for proctitis is undergoing chemotherapy, radiotherapy or a combination thereof.
A solid composition for treating proctitis comprising:
- a. intact blood-derived polyclonal antibodies that bind to a human tumour necrosis factor α (TNFα);
- and
- b. one or more of:
- gelatin, cocoa butter, polyethylene glycol, and a suppository wax.
A liquid composition (preferably an enema composition) for treating proctitis comprising:
- a. intact blood-derived polyclonal antibodies that bind to a human tumour necrosis factor α (TNFα);
- and
- b. one or more (preferably all) of:
- an antimicrobial, a suspension stability agent, an antifoaming agent, and a suspending agent;
- wherein the composition does not comprise means for protecting the antibodies during gastrointestinal transit.
The antibody composition for use, use, method, solid or liquid composition according to any one of the preceding claims, wherein the antibodies or composition have not been affinity purified.
The antibody composition for use, use, method, solid or liquid composition according to any one of the preceding claims, wherein the antibodies or composition have been subjected to a precipitation (and optionally filtration) step only.
The antibody composition for use, use, method, solid or liquid composition according to any one of the preceding claims, wherein the composition is a blood serum composition that has been subjected to a precipitation (and optionally filtration) step only.
The antibody composition for use, use, method, solid or liquid composition according to one of the preceding claims, wherein the composition is an ovine blood serum composition comprising intact blood-derived ovine polyclonal antibodies that bind to a human TNFα and that has been subjected to a precipitation (and optionally filtration) step only.
The antibody composition for use, use, method, solid or liquid composition according to any one of the preceding claims, wherein the composition is a blood plasma composition that has been subjected to a precipitation (and optionally filtration) step only.
The antibody composition for use, use, method, solid or liquid composition according to any one of the preceding claims, wherein the composition is an equine blood plasma composition comprising intact blood-derived equine polyclonal antibodies that bind to a human TNFα and that has been subjected to a precipitation (and optionally filtration) step only.
