Patent No. EP4197530 (titled "Ribociclib Tablet") was filed by Novartis on Apr 14, 2016. The application was issued on Nov 12, 2025.
This invention provides a coated pharmaceutical oral tablet comprising ribociclib succinate (also known as LEE011), a cyclin-dependent kinase (CDK1, CDK2, CDK3, CDK4, CDK5, CDK6, CDK9) inhibitor and glycogen synthase kinase-3 (GSK-3) modulator. The tablet core contains at least 40% w/w ribociclib succinate and may include fillers (cellulose, mannitol, di-calcium phosphate, lactose, microcrystalline cellulose), binders (hydroxypropyl cellulose, polyvinyl-pyrrolidone), and lubricants (magnesium stearate, stearic acid, talc, silicon dioxide, sodium stearyl fumarate). The tablet is finished with an aqueous moisture barrier coating comprising polyvinyl alcohol (PVA), such as Opadry® amb II. This PVA-based coating prevents tablet cracking and logo bridging defects observed with standard HPMC-based coatings (e.g., Opadry®), ensuring high stability, high drug load, and an immediate release profile.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
