#MSCOVID19 two swallows don’t make a summer

As you know I have had to backpedal with my SARS-CoV-2/COVID-19 advice in relation to anti-CD20 therapies. I have now had to reinterpret data on the role of immunoglobulins in protecting people from developing COVID-19 and severe COVID-19. I have been using the two Italian cases of X-linked agammaglobulinaemia who got COVID-19 and make a recovery as an argument that you don’t need B-cells and...

#MSCOVID19: an anti-CD20 backpedal

Science is not a religion and hence scientific advice, unlike beliefs, change as new evidence emerges. When the COVID-19 pandemic started we had to formulate advice on DMT use and their impact on SARS-CoV-2 infection and COVID-19 based on scientific principles and evidence of other viral infections. I created a table to summarise my opinions and as evidence has emerged I have updated the table...

#MSCOVID19 Anti-CD20 therapies and vaccines

Have we optimised the dose of anti-CD20 therapies to target the real MS or smouldering MS, i.e. disease progression independent of relapse activity (PIRA)? I did an iWiMS webinar on Wednesday covering anti-CD20 therapies and the risk of COVID-19 and severe COVID-19. I covered vaccine responses and how to be vaccine-ready or vaccine responsive to a future SARS-CoV-2 vaccine if you are on an anti...

#MSCOVID19: good news for anti-CD20ers

I am being asked why I have moved ocrelizumab and other anti-CD20 therapies into the low-risk categories of DMTs in my latest version of my DMT table. The reasons I use to justify the change are several-fold. Anti-CD20 therapies deplete B-cells and only have a small impact on T-cell counts and innate immune cell function. This is important because anti-viral responses don’t seem to be affected to...

Rituximab combination therapy

A dark age is when society regresses; it goes backwards in time. The shocking revelations in last week’s New England of Journal of Medicine on the dire situation of some type 1 diabetics upset me and indicates we may be entering a dark age. An age when we are forcing our patients to turn their backs on innovation because they, or society, can’t afford to purchase the necessary medications...

the HYPE study

It is clear that many MSers on continuous anti-CD20 therapy are concerned about the risk of developing hypogammaglobulinaemia and subsequent infections. Yesterday, I spoke to several neurologists at the O’HAND investigators meeting in Barcelona who informed me that they are considering giving their ocrelizumab-treated patients hyperimmune globulin replacement therapy (HYPE-Ig-RT) when they...

Who said anti-CD20 therapies were safe?

When I highlighted the risk of hypogammaglobulinaemia and infection in MSers receiving anti-CD20 therapy after ECTRIMS I go a very long email from someone from Roche playing down the risks. The following study is therefore very timely and shows that when comparing interferon-beta, glatiramer acetate, natalizumab, fingolimod and rituximab with each other it is rituximab that comes out worst in...

Derisking anti-CD20 therapy

An important highlight of ECTRIMS this year was the data on the safety of the anti-CD20 therapies as a class. It is clear that prolonged, and sustained, B-cell depletion is not safe. Hypogammaglobulinaemia will become a problem with the risk of both common and opportunistic infections.  Stephen Hauser presented the 7-year ocrelizumab safety data and there is a clear uptick in infections in...

Why is everyone drinking anti-CD20 kool-aid?

Prof G will ocrelizumab and rituximab prevent SPMS? Just back from the COMBAT-MS stakeholders meeting in Pasadena with the Kaiser (Kaiser Foundation Research Institute) and Swedish (Karolinska Institute) trial teams, PCORI (Patient-Centered Outcomes Research Institute) and many brave an wonderful people with MS and their families. The COMBAT-MS study (NCT03193866) is recruiting well and is on...

ADIOS

Yes, why can’t we use anti-CD20 therapies as an immune constitution therapy (IRT) or at least adapt the dose based on B-cell reconstitution kinetics? And if we can’t beat the Swedes why can’t we join them? ADIOS = ADaptIve Ocrelizumab dosing Study There is mounting evidence from NMO and rheumatology that anti-CD20 therapies can be used as either a maintenance therapy or an immune...
