Patent No. EP2805723 (titled "Cladribine Regimen For Treating Multiple Sclerosis") was filed by Merck Serono on Dec 20, 2005. The application was issued on Jan 17, 2018.
Oral Cladribine treatment regimen for multiple sclerosis that allows reduced dosing and fewer side effects compared to IV or SC administration. The regimen involves multiple cycles of 1-7 days of oral Cladribine followed by Cladribine-free periods. The total Cladribine dose is lower during maintenance periods. This sequential oral dosing reduces side effects while still providing MS lesion suppression.

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.
