BRUSSELS, Dec 16 (Reuters) - Belgian biotech group Galapagos said on Tuesday that its research partner Janssen Pharmaceutica, a unit of Johnson & Johnson, had pulled out of a programme to develop a new drug to treat bowel disease.

Galapagos said it had received all rights to the GPR84 inhibitor programme which included the drug GLPG1205 and said it would continue with a phase 2 study of its own on patients with inflammatory bowel disease ulcerative colitis.

The group gave no financial details about the transaction.

It still has a string of drugs developments in its pipeline with pharmaceutical groups such as AbbVie, GSK and Servier.
