Patent No. EP4267105 (titled "Antibody Compositions And Methods Of Use Thereof") was filed by Bristol Myers Squibb on Dec 27, 2021. The application was issued on Mar 26, 2025.
A pharmaceutical composition for treating tumors via subcutaneous administration comprises nivolumab at approximately 120 mg/mL or 150 mg/mL, 20 mM histidine, 250 mM sucrose, 0.05% w/v polysorbate 80, 50 µM pentetic acid, 5 mM methionine, and 2000 U/mL rHuPH20. The composition utilizes nivolumab as an anti-PD-1 antibody, rHuPH20 as an endoglycosidase hydrolase enzyme, and methionine as a sacrificial antioxidant. The formulation is designed for delivery via vials, syringes, auto-injectors, or wearable pumps to improve patient compliance over intravenous administration. The composition may be provided as a unit dose with a total volume of less than 5 mL, delivering an effective dose of 250 mg to 2400 mg of the antibody.

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.
