The drug candidate was discovered initially using CAT's phage display technology and named D2E7. The key components of the drug were found by guiding the selection of human antibodies from phage display repertoires to a single epitope of an antigen TNF alpha. The ultimate clinical candidate, D2E7, was created and manufactured at BASF Bioresearch Corporation and taken through most of the drug development process by BASF Knoll, then further development, manufacturing and marketing by Abbott Laboratories

Plaque psoriasis

Adalimumab has been shown to treat moderate to severe chronic (lasting a long time) plaque psoriasis (Ps) in adults who have the condition in many areas of their body and who may benefit from taking injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light alone or with pills). Adalimumab has been shown to be effective therapy when used either continuously or intermittently in patients with moderate to severe psoriasis.

Juvenile idiopathic arthritis

Adalimumab has been shown to reduce the signs and symptoms of moderate to severe polyarticular juvenile idiopathic arthritis (JIA) in children four years of age and older. It is commonly used in combination with methotrexate and administered via a 20 mg pre-filled pediatric syringe, 40 mg pre-filled syringe or a 40 mg pen.

, ruled for CAT. In an unusual step, a draft of the judgement was not made available in advance.

A short version of the full statement of the proceedings was released. In it Justice Laddie remarked, "Abbott was in error when it made its first royalty payment to CAT calculated on the basis that only 2% of the Net Sales was due. It should have calculated on the basis of the full royalty of just over 5% and should have paid and continued to pay CAT accordingly." Justice Laddie went on to observe "...that the construction advanced by Abbott does violence to the language of the agreements, renders them obscure and makes little or no commercial sense. For this reason CAT wins the action."

Abbott was required to pay CAT US$255m, some of which was to be passed to its partners in development. Of this sum, the Medical Research Council

received US$191m, and in addition, Abbott was asked to pay the MRC a further US$7.5m over five years from 2006, providing that HUMIRA remains on the market. The MRC also is to receive a further £5.1m (sterling) in respect of past royalties.

Patent Litigation

On May 29, 2009, Johnson & Johnson's Centocor unit, the maker of Remicade, which is also a TNF inhibitor, won a ruling for $1.67 billion from Abbott Laboratories, the maker of Humira, for patent infringement on the process for making Humira.
