Masitinib for Multiple Sclerosis-Phase IIB/III trial results

Published 2021-01-27
Masitinib is a tyrosine kinase inhibitor which reduces proliferation of cells in the innate immune system such as mast cells, macrophages, and microglia, and there is recent evidence that it is effective in progressive MS. This video review how masitinib works, the potential side effects, and the results of clinical trials.

    excellent video, as per your usual! Thank you for this!
  • Thanks for breaking the evidence down for us so succinctly Dr Beaber! I'm encouraged that this could be a possibility for those of us over 60 with progressive disease. I just hope it's available soon! Otherwise I may have to go to the vet and bark like a pup! Lol!
  • @buffalobob870
    Nice to see therapies that show hope for progressive forms of MS. Would be nice to have the "right to try" philosophy extended to other conditions such as MS; especially those who have advanced to EDSS 5+. Great video!
  • @relledom
    Thanks for the great video, giving pwMS again some hope! Best regards from Germany!
  • I'm not a specialist, only a shareholder from France but your explanation was clear and well organized, thanks for this nice video. Hope for sick people that Masitinib will be authorized soon everywhere in the world
  • Thank you doctor for another cool and interesting video! Is the mechanism of masitinib the same as that of evobrutinib (in this case studied for RRMS)? I think this kind of research based on the innate response of the immune system is very promising. Thank you very much for making the results understandable for us!
  • @paul6150
    Ok, let's combine this with ocrelizumab and let's start tomorrow. Not trying to be funny, but 2 year trial starting from?? Plus some insurance company BS probably. I might be at EDSS 7 by then. Question: Is there a reason you can think of why this might not go along with other DMT? Combining stuff might be the only hope for progressive patients. Well maybe I am not in my most positive mood today.

    bonjour ce n'est pas possible d'avoir la traduction.... tout le monde n'a pas la chance de parler anglais merci
  • @RSsboy90
    Hey Brandon. Would you care to elaborate on what p-value means in the context of medical articles?
  • @Teslakoils
    Thank you for sharing sir. I was wondering what your personal opinion is on Mavenclad.
  • @Jesusleal10
    Hi Dr. Beaber. Do we know the cognitive benefits of taking BTK inhibitors? We know that disability-wise is awesome, but do we have data on Cognition and Brain Volume? Thanks.
  • @ghost8726
    Seeing as though the target of this drug is completely different than that of an ocrevus or the other popular ms drugs & we see results as good as those, I would love to see a combined treatment study using this & ocrevus. Ocrevus seems to be the most effective with least side effects and risks, also reduce brain atrophy ( something which ( might be wrong ) only lemtrada and hsct show ) & has amazing 6 year results.
  • Dr. Beaber, please study the IVM (Ivermectin) drug, which deals with P2X4 receptor and has very promising remyelination properties.
  • @rawsomehappy
    Nice when treatments aren’t pigeon holed for singular conditions and show promise across the human playing field. I saw a promising study using proprionic acid Your thoughts?
  • @Lukashumungus
    Hello Dr. Brandon Beaber So if it works how long wold it take to be available from now?
  • @roberture5903
    Would this medication be in pill form if approved ? My therapy now tysabri infusions. Thankyou for another informative video.
  • @aditya50499
    Sir, as I see, there are some BTK inhibitors that are already being used to treat certain cancers in humans and this one, Masitinib, has been approved to treat mast cell tumours in dogs. It seems the company, AB Science is now trying to repurpose the same drug to treat MS.
