Title:	Solid pharmaceutical formulations comprising BIBW 2992
Abstract:	The present invention relates to a pharmaceutical dosage form containing the active substance BIBW 2992 as the dimaleate salt, providing an immediate release profile of the active substance, further, the invention relates to compacted intermediates comprising BIBW 2992 dimaleate salt (BIBW 2992 MA.sub.2) in form of a powder prepared using a combined roller compaction and sieving step from BIBW 2992 MA.sub.2, intermediate blends prepared from said compacted intermediate as well as solid oral formulations providing an immediate release profile of the active substance, made from said compacted intermediate or from said intermediate blends ready for use/ingestion, e.g. capsule and tablet formulations such as uncoated or film-coated tablets prepared by direct-compression, and methods for their production.

Patent Claims:	1. A compacted intermediate consisting of BIBW 2992 MA.sub.2 (API salt) and an amount of 0 to 1.0% of a lubricant, calculated on the amount of API salt by weight, in form of a powder with a particle size distribution of x10<200 .mu.m, 1 .mu.m<x50<300 .mu.m, 75 .mu.m<x90<600 .mu.m, obtainable by roller compaction, combined with at least one sieving step after compaction. 2. The compacted intermediate of claim 1 characterized by a poured density (.rho..sub.p) in the range of 0.2 g/mL<.rho..sub.p<1.0 g/mL and/or a Hausner Factor (HF) in the range of 1.00<HF<1.30. 3. An intermediate or final blend prepared from the compacted intermediate according to claim 1. 4. The intermediate or final blend according to claim 3, further characterized by contents selected from components (a) to (g): (a) compacted intermediate of BIBW 2992 MA.sub.2 in an amount of about 1 to 99% by weight, (b) optionally one or more carriers in an amount of about 10 to 99% by weight, (c) one or more binders in an amount of about 0 to 99% by weight, (d) one or more glidants in an amount of about 0 to 10% by weight, (e) one or more disintegrants in an amount of about 0 to 10% by weight, (f) one or more lubricants in an amount of about 0 to 10% by weight, and (g) 0 to 10% by weight of further excipients and/or adjuvants, wherein presence of at least one of components (b) to (g) is mandatory but also two up to at most all six of the optional components (b) to (g) are allowed to be present in addition to component (a) in the intermediate and final blend, the sum of all components adding to 100%. 5. A solid oral formulation ready for use/ingestion prepared from the compacted intermediate of BIBW 2992 MA.sub.2 according to claim 1. 6. The solid oral formulation according to claim 5 selected from powders, granules, pellets, tablets, capsules, chewable tablets, dispersible tablets, troches and lozenges. 7. A solid oral formulation, wherein the formulation is a tablet and obtained by direct compression of a final blend according to claim 3 or by tableting of pellets or granules obtained by conventional wet-, dry or hot-melt granulation of an intermediate blend according to claim 3. 8. The tablet of claim 7, said tablet being uncoated or coated. 9. The tablet of claim 8, comprising 1 to 150 mg of the API, based on BIBW 2992 (the free base). 10. The tablet of claim 9, further comprising 50 to 500 mg of carrier, binder or a combination thereof, 0.1 to 5 mg of a glidant, 1 to 15 mg of a disintegrant, and 1 to 15 mg of a lubricant. 11. The solid formulation of claim 5, packaged in PVC-blisters, PVDC-blisters or a moisture-proof packaging material such as aluminium foil blister packs, alu/alu blister, transparent or opaque polymer blister with pouch, polypropylene tubes, colored blister materials, tubes, brown glass bottles glass bottles and HDPE bottles optionally containing a child-resistant feature, optionally comprising a desiccant such as molecular sieve or silica gel. 12. A method for producing the compacted intermediate of BIBW 2992 MA.sub.2 according to claim 1 in form of a powder comprising compacting by roller compaction combined with at least one sieving step. 13. The method of claim 12, wherein the roller compaction step is carried out with BIBW 2992 MA.sub.2 alone or, optionally, with a pre-blend of BIBW 2992 MA.sub.2 with 0 to 1.0% of a lubricant in a freefall or tumble blender to prevent major sticking on the compaction rolls. 14. The method of claim 13, wherein the roller compaction step is carried out on a roller compactor optionally with horizontally, vertically or 45.degree. angle alignment of the compaction rolls, which may be smooth or shaped on their surface; using a compaction force varying between 1 kN/cm and 20 kN/cm, at a compaction speed of the compaction rolls between 1 rpm and 30 rpm, and a gap width between the compaction rolls between 1 mm and 10 mm. 15. A solid oral formulation ready for use/ingestion prepared from an intermediate blend according to claim 3. 16. The solid oral formulation according to claim 15 selected from powders, granules, pellets, tablets, capsules, troches and lozenges. 17. The solid formulation of claim 15, packaged in PVC-blisters, PVDC-blisters or a moisture-proof packaging material such as aluminium foil blister packs, alu/alu blister, transparent or opaque polymer blister with pouch, polypropylene tubes, colored blister materials, tubes, brown glass bottles glass bottles and HDPE bottles optionally containing a child-resistant feature, optionally comprising a desiccant such as molecular sieve or silica gel. 18. The solid oral formulation according to claim 16 which is in the form of a tablet selected from chewable tablet and dispersible tablet. 19.
