The invention relates to thienopyridazinones of formula (I): wherein: R1 is C1-6 alkyl, C2-6 alkenyl or C3-6 cycloalkyl which is optionally substituted by C1-6 alkyl, each of the above being optionally substituted by one or more halogen atoms; R2 is C1-6 alkyl; R3 is a group CO—G or SO2—G where G is a 5- or 6-membered ring containing a nitrogen atom and a second heteroatom selected from oxygen and sulphur adjacent to the nitrogen, and optionally substituted by up to 3 groups selected from hydroxyl and C1-4 alkyl; Q is CR5R6 where R5 and R6 are as defined in the specification; and R4 is a 5- to 10-membered mono- or bi-cyclic aromatic ring system, containing 0 to 4 heteroatoms independently selected from nitrogen, oxygen and sulphur, the ring system being optionally substituted as described in the specification, and pharmaceutically acceptable salts and solvates thereof. Processes for their preparation, pharmaceutical compositions containing them and their use in therapy, in particular in the modulation of autoimmune disease are also described.
