Ozanimod How does it work? Have we got a real clue?

Last week I wrote a post about how pharma may report on the next Cladrimod (cladribine or ozanimod/posenimod) study in “Dr Dooley will be happy that their uncited work from 2016 has been repeated….MS drugs affect memory B cells!”. In that post I made a prediction on how the lymphocyte subset data would be reported from the next MS drug so that the potential for memory B cell depletion...

Dr Dooley will be happy that their uncited work from 2016 has been repeated….MS drugs affect memory B cells!

Part of the scientific process is repetition, but at some point in time you need to believe it and move one. This study is Open access and so you can read it, but it is further supportive evidence of the memory B cell hypothesis Memory B Cells are Major Targets for Effective Immunotherapy in Relapsing Multiple Sclerosis.Baker D, Marta M, Pryce G, Giovannoni G, Schmierer K. EBioMedicine. 2017;...

Swallowing difficulties in MS

Swallowing difficulty or dysphagia occurs in a third of MS cases. Aside from the discomfort, it is dangerous for small bits of food to go down the wrong way into the lungs rather than in to the gullet. The latter can lead to chest infections (termed aspiration pneumonia), and is the leading cause of death in neurodegenerative conditions including MS. Early review of swallowing by Speech and...

Ker ching

ProfG has been asking questions about the prescribing habits of his colleagues and asks why alemtuzumab and HSCT are not being used by some. I wonder if the other end of the spectrum will be questioned and the use of lower efficacy agents. This is going strong Rome BN, Tessema FA, Kesselheim AS.

Remyelination is a hot topic In the paper below they say “The view that differentiation of OPC into mature myelinating oligodendrocytes is required for successful remyelination in humans has been challenged recently. Measuring the integration of 14C derived from nuclear testing into DNA of oligodendroglial lineage cells Yeung et al. suggest that pre-existing oligodendrocytes and not...

CNS lymphoma in autoimmunity

Non-Hodgkin’s Lymphoma (a cancer involving predominantly of B cells) involving the brain, also known as primary CNS lymphoma (PCNSL) is something I see every year like clock work for the haem-oncology service at St Bartholomew’s Hospital, London. And despite the regularity of my visits, there is something extraordinary about the whole experience. You start to either vegetate or have...
