Taganti-CD20

My position on anti-CD20 therapies has been criticised, why?

Barts-MS rose-tinted-odometer: ★★★★★ I have recently been criticised by a colleague for supporting the DODO (double-dose ocrelizumab study) and the ADIOS (adaptive dosing ocrelizumab study) studies. How you can I on the one hand support more ocrelizumab and on the other hand suggest reducing the dose in the longterm. I responded that it is all about timing and how you use anti–CD20...

#MSCOVID19: getting ready for the vaccine

Informing patients about their potential coronavirus risks associated with anti-CD20 therapy is complicated and resulting in our patients being given different advice depending on who they see. The reason for this is that we don’t have the direct evidence to be able to dissect out why people on anti-CD20 therapy are at higher risk of COVID-19 and at higher risk of being admitted to hospital with...

The tortoise has finally arrived

The FDA has just approved ofatumumab for patients with relapsing MS. See Novartis’ press release below. Ofatumumab delivers powerful efficacy with a favorable safety profile and can be self-administered at home, addressing significant unmet needs for people living with relapsing forms of multiple sclerosis (RMS)1 Approval based on two Phase III ASCLEPIOS studies demonstrating significant...

A false sense of security?

Just catching up with my reading. Whilst I was away on holiday the ASCLEPIOS I and II trials was published in the New England Journal of Medicine.  There is little doubt that ofatumumab is superior to teriflunomide when it comes to suppressing focal inflammation, i.e. relapses, MRI activity and peripheral blood neurofilament levels. However, ofatumumab’s effectiveness against teriflunomide on the...

#MSCOVID19: vaccine readiness

Will Prof G have to eat his proverbial hat? I have been telling people that an effective SARS-CoV-2 vaccine is a long way away and that we shouldn’t expect a commercially available vaccine for another 12-18 months. Maybe I am wrong. The Moderna phase 1 results were published by the NEJM yesterday and are more impressive than I expected. These results are so important because the vaccine is...

#T4TD when it comes to Anti-CD20 therapy body size counts

Did you know that if you are a large person standard dose ocrelizumab is not as effective as it is in a small person?  When looking at the efficacy of anti-CD20 therapies such as ocrelizumab you shouldn’t bother looking at relapses and focal MRI activity (Gd-enhancing lesions or new T2 lesions) when comparing effectiveness between doses and competing products. Relapses and MRI lesions are...

#MSCOVID19: COVAX or Coronavirus Ocrelizumab Vaccination Study

Anti-CD20 therapy not only increases your chances of getting COVID-19 but also increases your chances of developing severe COVID-19 and having to be admitted to hospital for treatment. I have argued that the likely mechanism is to be due to anti-CD20 therapies blunting important cross-reactive anti-coronavirus immune response acquired from other community-acquired coronaviruses. If this is...

#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...
