Questions and answers Feb 2018

If you have a question this is the place for you

  1. Hello,

    I am 28, female and living in The Netherlands.
    I was diagnosed in June 2017 (bilateral internuclear ophthalmoplegia) + migranes + nausea + sensory symptoms. MRI showed 5 non-enhancing brain lesions (one of them in brainstem). Lumbar puncture revealed the presence of oligoclonal bands.

    INO resolved but I still have some mild sensory symptoms and fatigue.
    3-month followup MRI (end of Aug) showed no changes in lesion load/volume.

    Started with 40mg Copaxone end of September.

    Question nr 1: Dr recommended MRI at 12 months after Copaxone start, but should I also maybe rebaseline at 6 months after Copaxone start (right before it reaches therapeutic levels)? Because if any lesions are found at 12 months how can I know whether they were created before or after Cop started working?

    Question 2: Would I be a good candidate for Cladribine or Alemtuzumab?

    Question 3: I also have vit D deficiency. What would be a good supplementation dose for me? Dr recommended 800IU/day, but isn’t this a bit low? Can vit D have a beneficial impact on my disease?

    Thank you beforehand for your reply.

    Best regards,
    MP

    1. as I know INO is a result of a relapse which involved the Brain stem or Posterior fossa! This is a highly alarming. My sister had similar and she progressed quite fast (after 2 years from EDSS 1,5 to EDSS 3,5). Her neuro did not want to switch we looking for another who helped. She is stable with Gilenya. If I would be in your place I try everything to change a highly effective therapy. Cause you a young lady you should change to Cladribine or Alemtuzumab! (Ive answered your Q2 without reading.) Switch-switch-switch.


      Q3: vitD recommended 4-5000 IU daily! Please write an email to the Vitamin D council!

    2. Thanks a lot for your reply, but isn’t that supposed to be a q&a where doctors reply?

      I am indeed very alarmed now by your answer, because I ve visited a couple of neuros, and nobody wanted to switch me.

      Is it the case that all cases that start with INO progress fast?

    3. Question 1. Good point Re-baselining gives you an oppertnity to check efficacy, The question is how long does it take to get efficacy.

      Question 2. To get alemtuzumab you need to be active (MRI lesion in Europe) and for cladribine highly active. We can't give personal advice. I am not a doctor. Each persons circumstance are different and you need to talks these things through. The blog is not the place for consultations.

      In the UK there is a situtation that copaxone is not considered cost-effective but it is a relatively safe agent.

      Question 3. See the post below your question there are lots of posts. Try the search function.

      The are stuff in education I think in research day that talks about potential prognosis and what number of signs I would never say always as you invariably get exceptions

    4. That's only our experiences, and my sister had new and enlarging lesions so will be well-informed and if U can switch hit hard!

    5. Thank you for replying to me and I am sorry I posted a personal question. I am new to this blog and I realised it after I posted it.

      Would there be any chance that Dr Giovannoni replies to my questions? I could give you my email if that’s not really the place for him to do so.

      I would really really appreciate that.

  3. Hello. I would just like to ask given the push now on to develop neuroprotectors to help treat patients with MS, can you see any that may become available fairly shortly and if so do you think that the first round of neuroprotectors will only be useful in patients with relapse and remitting MS or can you see them providing protection for all MS patients? Also do you think that neuroprotectors will supercede current DMTs and the current therapeutic need to suppress or modulate the immune system or will it be more likely that they will be used as an add on to current treatments? Thank you.

    1. Neuroprotectors are needed for everyone with MS there is damage to nerves from start to finish and inflammation start to finish we need to layer treatments rather than monotherapies. The problem you have now is because you have effective DMT so to do trials ethically you will need to have DMT in the trial. You may get a DMT that have neuroprotective and anti-inflammatory but mechanistically additinal neuroprotective

      Can I see if any become available shortly...I bet you have them already as symptomatic agents may well have neuroprotective activity.

    2. Neuroprotection will almost certainly been needed for all subjects.

    4. As someone with ~2 decades of (slow) PPMS who - despite some of the repeated and forceful opinions of your team - is not about to knock 7 bells out of their immune system, I would like to see a lot more discussion of neuroprotectives on here.

      "I bet you have them already as symptomatic agents may well have neuroprotective activity."

      Which agents? I don't require/take any symptomatic drugs at all at the moment.

      Delete
    5. One thought of how nerves get damaged is because they are working too hard and get exhausted and they get toxic amounts of calcium Ions. Therefore drugs that stop the excitatory ions from developing will probably be neuroprotective. There are a large number of possible treatments that do this.

      The problem is there is no evidence in humas so I won't name the drug names,

  4. Hello!
    I am looking for information on estrogen therapy for MS. Why is this not a hot subject for research?
    I have MS and the only real symptom free periods in my 10 years with MS were my 2 pregnancyes and 6 months on estrogen patch. However I developed ovaryan cysts so my gyno stopped estrogen. 2 months after my last estrogen patch I am in a biggest relapse ever.

    What are your thoughts on estrogen and MS?
    Thank you,
    D.

    1. Why is there not hot,...there is little pharmaceutical interest and also MS affects men too.

  5. Hi there,

    I've posted this before, but my comments never seemed to publish, so my apologies for the repetition! What are your thoughts on using mass spectroscopy for use in dx of CIS in the absence of any lesions on MRI? More specifically the NAA, choline, and creatine ratios can suggest a demyelinating event that isn't picked up as lesions in the early stages of MS.

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880684/
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2907390/
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3652709/
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5504183/

    All of these seem to support using mass spec as a means of measuring active MS, but what about those patients that are experiencing MS-like symptoms in the absence of lesions? Should they be labeled as CIS? Should DMTs be started?

    Thanks so much for your input!

    1. MRS is not common. NAA also has problem as it was used as a measure of nerve content but it NAA loss can recover so what is it really measuring and for dx you need lesions in "time and space"..does mass spec give you the in space?

      I'm not a neuro

      Delete
    2. Thanks ever so much for your reply.

      MRSI is becoming more common (here in the U.S., that is) and reports are usually given as a Z-score from the callosal and supra callosal areas of the brain, so if levels are different, hypothetically this could give you the "in space" needed.

      CIS is a first MS-like event, so my question is: if this is a flag for early disease activity, shouldn't more action be taken to preserve what has not yet been lost?

      Thanks again for your answer.

    3. I personally think treat early this is why it was suggested natalizumab might be a good first option to stop further episodes whilst working on diagnosis.

  6. Sorry I commented in the wrong publications.

    In my last consultation now in December 2017 it really comes down to the fact that MS affects a lot more women than men. There were only two men for about 12 women who would be seen on the day of my routine appointment.
    So I'm interested in the gender difference in MS, and how hormones can influence it.

    Testosterone sends mast cells to secrete IL-33 in males. It appears that IL-33 (or "guarded molecule" as it was called) triggers a series of chemical reactions that block the development of Th17 immune cells.

    http://www.pnas.org/content/early/2018/01/25/1710401115

    And it will be one of the posters of ACTRIMS 2018, two teenagers developed MS shortly after taking the HPV vaccine.

    They didn't conclude whether it was a "coincidence" that they developed MS, or whether the vaccine was somehow recognized as an antigen by a deregulated immune system, or whether the vaccine actually triggered the disease.

    Here in Brazil we have had some reported cases of girls who took the HPV vaccine and who, as it turned out, developed Guillain Barre Syndrome.

  7. I've noticed of late patients questions
    Via comments are not being answered. Which is okay as fulltime researchers you will not have time. So why allow patients to ask questions and then not answer them? I personally think you spend the time finding a cure. But We both know that's not going to happen. pharma money will buy it and lock it in a vault. There will be no cure for ms until another cash cow appears.

    1. If ProfG throws in a curve ball, he will need to answer the comments. His new post has sparked considerable debate internally and externally

      If MS is autoimmune and we know the antigen I know what we would do, we have done it in animals hundreds of times but as we have shown there is no quick answer because the way the scientific process has been allowed to develop.

      The best way to a cure is treat early abd effectively

  10. What are the possibilities for slowing the progress of the disease us with the diagnosis of G37, mild pleocytosis and OBS negative CSF, ANA nucleoplasmic homogeneous positive, without any other symptoms or findings suggestive of systemic connective tissue disease, and with over 10 lesions on the brain and spinal cord. How many people are in such a situation? Whether the prognosis is better or worse than the classic ms?

  11. Mri usefullness

    "We also assessed the predictive value of MRI metrics
    commonly measured in MS clinical trials over 2-year
    intervals, and found no association between new T2
    lesions or gadolinium-DPTA–enhanced lesions and worse
    long-term outcomes."


    Edss increase over 2 yeras its not predictive

    "Similarly, an increase in the EDSS score over 2
    years was not associated with worse long-term prognosis.
    Thus, short-term increases in EDSS do not necessarily
    predict future accumulation of disability in RMS patients
    over the longer term, a conclusion also reached in a
    pooled analysis of patients randomized to placebo arms in 31 clinical trials.48"

    Neda (For what ?)

    "Because neither clinical nor radiographic
    features over 2 years had predictive value, it is
    not surprising that the combined measure of these variables,
    NEDA, was also not associated with long-term disability
    risk. Although this observation must be
    interpreted with caution because of the relatively small
    number of NEDA patients in our cohort, another recently
    published observational study also found that the proportion
    of patients meeting a NEDA definition declined
    substantially over time.49 These observations challenge
    the concept that NEDA represents remission. Although
    NEDA may be a useful measure for assessing relative
    therapeutic efficacy, many patients who meet NEDA criteria
    over 2 years go on to develop clinically significant
    disability. Worsening in patients who meet the 2-year
    NEDA endpoint could result from active spinal cord disease
    not captured with brain MRI, progressive axonal or
    neuronal degeneration, or an escape from a true but transient
    remission state. A recent study that incorporated
    thresholds for acceptable brain volume loss for NEDA
    found that one-third of NEDA patients treated with fingolimod
    still experienced significant brain volume loss
    during the NEDA interval, indicating that ongoing tissue
    injury occurs in NEDA patients.50"

  12. Autoimmune disorders such as rheumatism or type 1 diabetes are on the increase world-wide. Regulatory immune cells protect healthy individuals from the disorders and combat disease progression in affected individuals. So far, little is known about the group of regulatory B cells which play a role in this context. Researchers of the Paul-Ehrlich-Institut (PEI) and the University Hospital of Würzburg found a marker, the tumour necrosis factor receptor 2 (TNFR2), which makes it possible to identify and enrich these cells. Frontiers in Immunology published these research results online on 19th January 2018.

    1. Thanks I will have a look but my concern is this automatic jump that IL-10 producing cells are regulatory.


      They may be but IL-10 is a B cell growth and differentiation factor so IL-10 producing B cells may simply be present to promote B cell growth. Likewise tumour necrosis factor is a B cell survival factor so not surprising that they express TNF receptor. Many of the B cell markers are part of the TNF superfamily

  16. News from Biotin

    A key finding was that MD1003 led to significant improvements in patients’ EDSS and TW25 scores at nine months, compared with the placebo-treated patients. The treatment’s benefits held at 18 and 30 months, researchers said.

    After the placebo group switched to MD1003 at nine months, researchers saw no differences in new EDSS results between the treated and control groups at months 24 and 36.

    But the group that received MD1003 for the first nine months continued to have better cumulative scores than those who initially received a placebo, then switched to MD1003. This suggested “that earlier treatment leads to a lower disability” at month 36, researchers wrote.

    Another finding was that at one year the patients who were initially treated with MD1003 performed better in the time to walk 25 feet test than the controls. This held during the follow-up period. In contrast, the performance of the group initially treated with a placebo worsened in the final year.

    In addition, the Clinician and Subject Global Impression scale results were significantly better in the MD1003-treated group during the first year, but there was no difference after that.

    The higher dose of ozanimod reduced the number of T2 lesions by 48 percent and the lower dose by 25 percent. The larger dose reduced T1 lesions by 63 percent and the smaller dose by 34 percent.

    Ozanimod also slowed brain volume loss. In the thalamus, the higher dose led to it slowing the loss by 39 percent and the lower dose by 34 percent, compared with Avonex. In the cortex, the larger dose led to brain volume loss slowing by 84 percent and the smaller dose by 61 percent.

  19. Cladribine in ACTRIMS:

    Effects of cladribine tablets on CD4+ T-cell subsets in the ORACLE-MS study: Results from an analysis of lymphocyte surface markers

    Conclusion: The first administration of cladribine tablets has a comparable magnitude of effect on CD4+ T-cell subpopulations, with no dramatic shifts in proportions. Further investigation is ongoing to explore the implications for the mechanism of action of cladribine tablets and the effects of treatment initiation at Year 2.

    Long-term lymphocyte counts in patients with RRMS treated with cladribine tablets 3.5 mg/kg: Total lymphocytes, B-, and T-cell subsets

    Lymphocyte recovery begins soon after CT treatment, with ALC, CD19+ B cells, and CD4+ T cells recovering and reaching threshold values by 7.5 months, 12 months, and 18 months, respectively, after the last dose in Y2. CD8+ cells never dropped below the threshold value.

    Alemtuzumab and Cladribine: A Comparison of Pharmacodynamics and Mechanism of Action

    Results: Alemtuzumab, a humanized monoclonal antibody, selectively depletes CD52-expressing T and B cells by antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. Following depletion, a relative increase in regulatory T cells (Treg) and decrease in proinflammatory cytokines occurs, potentially leading to rebalancing of the immune system. B cells return to baseline levels within 6 months; T-cell levels generally reach lower limit of normal by 12 months. The distinct pattern and time course of lymphocyte repopulation are consistent across treatment courses. Alemtuzumab restores Treg function by promoting long-term increase in Treg suppressive activity against myelin basic protein-specific Th1 and Th17 cells. Cladribine, a synthetic purine analogue, enters cells and is incorporated into DNA, leading to cellular apoptosis and/or autophagy. Cladribine is selective for lymphocytes due to their relatively high levels of drug-activating deoxycytidine kinase and low levels of drug-inactivating 5′-nucleotidase. After cladribine treatment, lymphocytes reach a nadir by 9 weeks (wk). In a clinical trial, slight lymphocyte recovery occurred before re-dosing at Wk 48. Reduced median lymphocyte counts persisted to Wk 96. Cladribine caused greater suppression of T than B cells in both the short and long terms, with modest decreases in neutrophils at Wk 96. Cladribine PD may include regulation of cell cycle, signalling, and proliferation genes; cladribine may also modulate pro-inflammatory cytokine profiles.

    Durable effects of alemtuzumab, an approved high-efficacy MS therapy, may be due to its selective depletion and distinct pattern of repopulation of circulating T and B cells thought to play a role in MS pathogenesis. Cladribine (approved in the European Union for the treatment of highly active relapsing MS) induces T-and B-cell apoptosis, in part by suppressing DNA synthesis and repair. These distinctions in MoA and PD may underlie differences in short- and long-term efficacy, safety, and the potential need for retreatment.

    Neutrophil and monocyte cell numbers remained within normal limits in patients with RRMS treated with cladribine tablets 3.5 mg/kg

    Conclusion: These data, together with the previously reported data on ALCs, support the concept that CT selectivity reduces adaptive immune cell counts, with a relatively minor impact on the innate immune system.

  20. Alemtuzumab in ACTRIMS:

    Alemtuzumab: Paradoxical effects on autoimmunity in individuals MS

    Secondary autoimmunity after alemtuzumab is a significant clinical problem, that requires a careful risk monitoring plan. It appears to arise from homeostatic proliferation of the peripheral T lymphocytes remaining after alemtuzumab, and failure of the thymus to restore the T cell repertoire. No predictive biomarkers exist, but there are hints that serum IL-21 may provide this in the future. A treatment which promoted thymic function after alemtuzumab may reduce autoimmunity, but none has been tried to date.

    1. Thanks we have suggested that driving new cells out of the thymus may not be the way to stop secondary autoimmunity. There results are not in the slides, but the abstract indicates the approach fails because the treatemnet does not cause cells to come out of the thymus in contrast to that found in monkies. However ma and miceybe this could have been expected as palifermin didnt do cause thymic output in an earlier study (Jacobson et al 2014).

  21. Miscellaneous

    Gene Therapy: An In Vivo Approach to Induce Immune Tolerance, Inhibit Neuro-Inflammation and Disease, Regardless of Genetic Background

    Results: Following EAE induction, Null mice began developing clinical signs of severe ascending paralysis, while AAV.MOG treated mice remained virtually symptom free (mean peak scores for Null vs AAV.MOG as mean±SEM for each epitope combination) [C57BL/6: 3.3±0.8 vs 0±0; 3.7±0.2 vs 0.25±0.3, and DBA/1: 3.5±0.4 vs 0±0]. Null mice also had substantial inflammation compared to AAV.MOG mice.

    Conclusion: In contrast to approaches using ex vivo engineering or expansion of Ag-specific Tregs, we have demonstrated that AAV8.MOG gene therapy can dynamically induce immune tolerance in vivo to multiple immunogenic epitopes of MOG which inhibits neuroinflammation and disease, regardless of genetic background,. Eliminating the need to identify HLA/MHC specific epitopes, makes this approach universally applicable as an effective therapy.

    Glunomab®: A Novel “Barrier-Protecting” Monoclonal Antibody Efficient in Mouse Models of EAE.

    Results:

    We observed that this antibody binds NMDAR located at the luminal surface of neurovascular endothelium at the vicinity of tight junctions of the blood-spinal cord barrier. When injected during the effector phase of Experimental Autoimmune Encephalomyelitis (EAE), it blocked the progression of neurological symptoms.

    Conclusion:

    This therapeutic effect was associated to a preservation of the blood-spinal cord barrier, leading to reduced leukocyte infiltration. Overall, this study unveils a critical function of endothelial NMDAR in MS, and highlights the therapeutic potential of strategies targeting the protease-regulated site of NMDAR.

    1. AAV.MOG is probably not going to go anywhere in MS. Responses to MOG are more associated with a type of NMO. There have been hundreds of MOG protein studies like this.

      Blocking NMDAR with an antibody will be bad news, only weak blockers eg. memantine are tolerated as NMDA receptors are useful.

  22. Miscellaneous from ACTRIMS II

    Low Dose Naltrexone in Multiple Sclerosis: Web-Presence Versus Scientific Evidence

    Results: We screened a total of 24 articles and included 18 publications (7 clinical investigations, 6 preclinical studies, 1 medical hypothesis, 4 commentaries). We excluded 6 studies irrelevant to MS. We found 3 clinical trials for LDN in MS patients which suffered limitations, and none provided conclusive evidence on the subject. However, all studies agreed on the safety of LDN. Google searches for the term “naltrexone and MS” yielded about 413,000 results and for “low dose naltrexone and multiple sclerosis” yielded about 184,000 results. Numerous patient-oriented websites discussed LDN and MS with phrases used such as “Overcoming Multiple Sclerosis” or “A Wonder Drug that Eases Multiple Sclerosis Side Effects,” among other claims. A limited number of websites, such as the National Multiple Sclerosis Society, provided evidence-based information for patients and caregivers on the subject and acknowledged the limitations of the scientific evidence

    Conclusion: It remains challenging for health care providers to answer various patient queries regarding potential effects of LDN in MS due to the inadequacy of clinical evidence. We identified a gap between readily available information off the internet for MS patients and actual scientific evidence. Preclinical investigations showed promising effects on inflammation and disease modification. Further studies are needed to determine the effect of LDN as an add-on therapy on quality of life measures such as pain, energy, social, cognitive and sexual functions in patients living with MS

    Vitamin D Supplementation May Have Therapeutic Effects in Neuromyelitis Optica Spectrum Disorder

    Conclusion: Physiological variation in vitamin D may exert a major impact on autoimmune and inflammatory disease. We observed that vitamin D supplementation can decrease IgG-NMO, EDSS and fatigue scale in participants with NMOSD and vitamin D supplementation may have therapeutic effects in NMOSD.

    Brain Atrophy after High-Dose Immunosuppressive Therapy and Autologous Hematopoietic Cell Transplantation for Multiple Sclerosis (HALT-MS)

    Brain volume loss may accelerate for months after HDIT/HCT due to the effects of chemotherapy-related toxicity and progression of WM lesion-related degeneration. However, over the long-term, adequate immunosuppression and HCT can reduce rates of brain volume loss to the range observed in normal aging.

  23. MS Hypothesis:

    Hypothesis: Multiple Sclerosis Is Caused By a Sequential Double Hit of Two Common Infections.

    Results: We propose a three-tiered hypothesis: 1) a model to explain clinical and epidemiological phenomena which argues that multiple sclerosis is a rare late complication of two sequential infections (with the temporal sequence of infections being important); 2) a proposal that the first event is infection with the helminth, Enterobius Vermicularis, and the second event is Epstein Barr Virus infection; and 3) a proposal for a testable biological mechanism to explain the model.

    Conclusion: We believe that this model satisfies many of the as-yet unexplained features of multiple sclerosis epidemiology, is consistent with the clinical and neuropathological features of the disease and is potentially falsifiable by experiment. This model may have elements which are relevant to other autoimmune diseases.

    Is MS a Transmissible Protein Misfolding Disorder?


    Results: MS-injected mouse brains exhibited significant degeneration of myelin with microglial activation in the corpus callosum, leukocortical junction and peri-ventricular region, assessed by QD9 and Iba-1 immunohistochemistry. Formic acid-resistant prion protein aggregates were detected in both white and gray matter regions. Protease resistance, often seen in more conventional prionopathies, was not detected in either human MS brain nor MS-inoculated mice.

    Conclusion: Our results are consistent with the hypothesis that MS may be a primary degenerative disorder caused by accumulation and propagation of atypical pathogenic prion protein, that can transmit pathology to humanized murine hosts. We speculate that these toxic pathological conformers are may circulate in the CSF and spread to various brain regions. The resulting degeneration of myelin and release of antigenic debris could secondarily trigger an autoimmune inflammatory response in genetically and environmentally predisposed hosts. Together, such a convolution of a primary prion-dependent degeneration, with secondary inflammation could explain the broad spectrum of human MS phenotypes. Our observations may shed light on the fundamental cause of MS.

    Multiple Sclerosis Patients Have a Increased Cellular Response to Autoantigens Which Cross-React with Proteins from Epstein-Barr Virus.

    Results: We tested the cellular response in 15 MS patients and 5 controls. Six MS had a proliferative response to septin-9, two to HNRNPL, and one to DLST. The maximum stimulation index for septin-9 was 4.8. No patient responded to more than one antigen. None of the controls had a proliferative response to any of the three antigens.

    Conclusion: A subset of MS patients has a T cell proliferative response to the autoantigen septin-9. Further investigation with larger numbers of patients and controls is needed, along with determination of the cytokine profile and phenotype (CD4 vs. CD8) of the responding cells. This work suggests a unique mechanism for autoimmunity, whereby B cells producing an anti-EBV immunoglobulin which cross-reacts with a self antigen stimulate an autoreactive T cell response. If further work supports the pathogenic potential of the septin-9 reactive T cells, then induction of tolerance to this antigen would be an attractive approach to an effective, antigen-specific treatment with minimal toxicity.

  24. Axonopathy & Remyelination:

    A Novel In Vivo Screen for Oligodendrocyte Differentiation and Myelination

    Results: GC1, a thyroid hormone receptor agonist, significantly increased mpz promoter activity. Transgenic zebrafish are well suited to establish the details of the drug’s pro-myelinating effects, and our studies demonstrate that GC1 increases myelin internode length and number and myelin RNA levels.

    Conclusion: This novel in vivo zebrafish screen is currently in use, screening pathway-specific libraries for new drugs to enhance myelination.

    A Novel Subset of Neutrophils Induces Axon Regeneration Following Transection

    Conclusion: A novel subset of Ly6GlowCD14+ neutrophils is capable of driving regeneration of transected CNS axons. These cells secrete a pro-regenerative soluble factor, and recruit arg+ CD206+ monocytes to the site of injury. Our findings may lead to the development of novel immunomodulatory drugs, or the repurposing of immunomodulatory drugs already in clinical use, to promote the differentiation and expansion of neuroregenerative neutrophils in patients with axonopathy, including MS.

  25. This recent study - https://plan.core-apps.com/actrims2018/abstract/09be07f9cacd4c5743fd28fd3758a3f8

    is slightly different than research released at ECTRIMS this year:

    http://www.mdalert.com/ms/ectrims/article/highdose-biotin-increases-inflammation-and-relapse-in-ppms

    You have one poster session, this article citing, ACTRIMS presented research, saying Biotin slows disability and ECTRIMS (link I include above) urging caution – made things worse, at least as measured by MRI and relapses.

    ECTRIMS – smaller sample and measuring relapses and MRI activity
    ACTRIMS – no info on whether they used MRI or just monitored changes in 25TW test. Makes me wonder about disclosures/sponsors and whether Biotin good or bad. Should I be taking? I have Progressive MS. Longest time docs thought I have RRMS - really have PPMS or SPMS - never had a relapse.

  28. The results of the clemastine fumerate study were "modest" in regenerating myelin. I had difficulty finding the original study so not sure, but clinically significant, no? I would call the effects of the first line DMDs modest-imagine if I only showed up at work 35% of the time! I took the max dose of CF and had no side effects. Bonus: no more allergies. Wouldn't it be best practice to put all RRMSers on CF? Thanks for your time guys.

      in those 2 places. The only stem cells that worked were done at
      Tisch Center and those are experimental right now. The other
      stem cell therapies seem mostly designed to raise monies and not cures.

      Another experiment option is Atara Bio's Tcell therapy that just got FDA trial approval. It started in Aus. but not in US or EU yet.

    2. Stem cells or HSCT treatment? Mexico has no regulations for the regenerating stem cell clinics so it can be a scam too, but the University of Mexico who performs the HSCT has a very good reputation as well as qualified doctors.

      Either way this is not the place to do your research about something you have already put yout money on.

    2. A death is an adverse effect and gets reported. However it could be a car accident someone choking on a fish bone and have nothing to do with a drug side effect.Also you need to know how often the drug is being used to get an idea if there is something unusual.

      However that you can find such information shows that the company's are taking the monitoring of their drugs seriously

      I would be most interested in the deaths related to infections.

      Delete
    3. 45 deaths in 6 months seems a lot. Zimbryta was banned from EMA for 2 deaths. It seems that at least the drug needs to come with certain guidelines, like Tysabri. Doctors seem to be concerned not only for the respiratory infections but also for heart related issues. It could be something that the right dosing could fix. But for now it looks concerning.

      I was predicting disease activity in some people

      http://multiple-sclerosis-research.blogspot.com/2017/09/hot-topic-at-ectrims-late-breaking-news.html

      Happy that if this didnt happen, but we then have to think the PDE4 activity is not important or is telling us something.

      Here is how the company says it works
      It is small molecule glial attenuator that suppresses pro-inflammatory cytokines IL-1ß, TNF-a, and IL-6, and may upregulate the anti-inflammatory cytokine IL-10. It has additionally been shown to be a toll-like receptor 4 (TLR4) functional antagonist that may contribute to its attenuation of neuroinflammation.

      While considered a New Molecular Entity, or NME, in the United States and Europe, it involves redirection of an approved drug, ibudilast, which was first approved in Japan more than 20 years ago. Ibudilast has been prescribed to over 3.2 million patients and has a good post-marketing safety profile.

      As for clinical trial...if the US company had supplied the drug for the MS-SMART (multi centre trial throughout the UK including Barts) as requestedd the second trial would now have been finished. They did prozac because of this.

      As for phase III, I dont know about this.

    2. Thanks MD. At least the ground is starting to move for Progressive and Secondary. Do you have any positive views of statins phase 3 trial in 2nd progressive?

      Delete
    3. Yes I have some positive views

      This reminds me to write paper on potential mechanism of action as the answer I got from one of people behind the study was useless.

      The genetics and an increasing number of studies point towards the cholesterol pathway as being important in neurodegeneration in MS and Alheimers. There is positive data from the phase II and hopefully this will repeat.

      However, with a pharma hat on, I would say the phase 3 has a flaw in that there is no dose-response. They are sticking with the high dose that will cause side effects for some without proving the lower, standard dose is ineffective. However to do a lower dose it would make the cost too high to add an extra 500 people in the study.

      So the regulators should say go away and prove that a lower safer dose does not work. Will they do this.

      I guess the view is do the trial and everyone will change...people power but it means it is one rule for pharma and a different rule for the rest.

      So the question I have is this, what happens when the trial is positive. What happens then?

      We all start using statins, but will it be better than siponimod or ibudilast which has done one trial, if it siponimod gets a licence you would need two statin trials if you have to do it like pharma.

      I guess it is better to do something rather than nothing, but it is clear that MS is inflmaatory from beginning to end and is neurodegenerative from beginning to the end so why not try deal with both problems?
