Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Specific Aims:
* To compare pre and post anti-COVID-19 immunity after a booster vaccination in PWMS who initially test negative for neutralizing antibodies to COVID-19 after initial vaccination;
* To determine how disease modifying treatments, baseline antibody panels and lymphocyte subsets associate with the efficacy of booster vaccines;
* To compare immune responses between homologous vs. heterologous booster vaccination.
Research Implications:
It is hoped that the results of this study will help guide clinical recommendations on the use of booster vaccination and whether to endorse heterologous versus homologous boosters. It is also hoped that this study will add to the growing body of data on COVID-19 immunity after vaccination in PWMS on various disease modifying treatments (DMTs).
Hypotheses:
* Booster doses of COVID-19 vaccines will improve antibody-based immunity to COVID-19in PWMS who initially test negative for neutralizing antibodies to COVID-19 after initial vaccination;
* This boost in immunity will occur irrespective of disease modifying therapy (DMT);
* Heterologous prime-boost combinations will show greater immune responses than homologous prime-boost combinations.
Background:
Multiple Sclerosis (MS) is an autoimmune condition associated with focal inflammatory infiltrates in the brain consisting of T and B lymphocytes, macrophages and activated microglial cells, with the principal target being the myelin sheath of central nervous system (CNS) axons. The approach to treating MS involves disease-modifying therapies (DMT) that have the effect of reducing access of potentially myelin-autoreactive immune cells to the CNS compartment. These treatments are shown to reduce exacerbations of disease and, to some degree, delay progression of neurological disability, both by clinical assessment, and, by the best surrogate marker to date, magnetic resonance imaging of the brain.
DMTs used to treat MS target adaptive immune responses in various ways. These include medications that shift cytokine and lymphocyte subsets towards less inflammatory activity, interfere with trafficking of lymphocytes in the circulation or central nervous system, or otherwise inhibit lymphocytes through nonspecific or subset depletion.
Approved and off-label treatments for MS include:
1. anti-CD20 (CD20 is a B lymphocyte receptor) monoclonal antibodies (ocrelizumab, rituximab and ofatunumab);
2. lymphocyte-sequestering drugs (fingolimod, onzanimod, siponomod);
3. adhesion molecule antibodies that prevent CNS lymphocyte trafficking(natalizumab);
4. nuclear erythroid 2-related factor two (Nrf2) modulators (dimethyl fumarate, diroxmel fumarate);
5. nonselective lymphocyte-depleters (cyclophosphamide, cladribine, alemtuzumab);
6. replication blocking lymphostatic drugs (teriflunomide) and immune modulators (interferon, glatiramer acetate).
All of these mechanisms could, theoretically, influence immune responses to vaccination. Live or live attenuated vaccines are contraindicated with several DMTs due to the risk of immune suppression. For COVID-19 immunity, both B and T lymphocyte activation is important. DMTs that are more immune-suppressive have shown attenuated responses to influenza vaccines and, presumably, would show the same for COVID-19 vaccines. These include the lymphocyte-sequestering drugs (e.g., fingolimod, onzanimod and siponimod), the antiCd20+ depleting drugs (e.g., ocrelizumab, ofatunumab and rituximab), and the general immune suppressants (e.g., alemtuzumab or cladribine). DMTs that have not been shown to inhibit immune responses to influenza vaccines include the interferons, glatiramer acetate, dimethyl fumarates, diroximel, and teriflunomide.
Currently three COVID-19 vaccines in the U.S. have either been approved for use or granted Emergency Use Authorization by the U.S. Food and Drug Administration (FDA). BNT162b2, manufactured by Pfizer, Inc. and BioNTech, Inc. and mRNA-1273, manufactured by Moderna, Inc., are RNA-based vaccines. They consist of modified COVID-19 mRNA sequences for the receptor-binding domain (RBD) of the M-spike protein. The mRNAs enter host cells via a lipid nanoparticle delivery system, where they are transcribed by host cell enzymes to produce a stabilized prefusion SARS-CoV-2 spike protein (S-2P), which localizes to the cell surface and presented as antigen for the host immune system. Ad26.COV2.S, manufactured by Johnson \& Johnson/Janssen, is a dsDNA vaccine that employs a similar strategy, the difference being that it enters the host cell nucleus via a non-replicating adenovirus vector, where it is transcribed to make spike protein.
In some literature reviews and studies, PWMS, including those on a wide spectrum of DMTs, do not seem to be at greater risk per se of increased morbidity and mortality from COVID-19 infection. A review of 873 published cases of COVID-19 multiple sclerosis patients, found that the overall mortality rate was 4% and that an additional 3% required some form of ventilation. Furthermore, immune suppressive treatments did not appear to be a risk factor for severe disease. An unfavorable prognosis for 28 PWMS who contracted COVID-19 in a Spanish study was related to older age and greater disability. These and other observations have prompted some to speculate that relative immune suppression may actually protect PWMS against inflammatory storm that accompanies severe COVID-19 infection. On the other hand, a meta-analysis of 84 reports of PWMS with COVID-19 infection and their DMT treatments, while not finding a relationship between the type of DMT and COVID-19 course, did find that the highest mortality rate, e.g., 4% out of a 1.8% overall mortality rate of those infected, was in persons treated with rituximab, a monoclonal antibody that suppresses B lymphocytes and antibody production. This higher incidence of severe COVID-19 infection in MS patients on rituximab was confirmed by another retrospective study. A similar monoclonal antibody, ocrelizumab, was found to be associated with suppressed COVID-19 specific antibodies compared to other DMTs among 59 PWMS who had laboratory-confirmed COVID-19 infection. However, COVID-19 specific T lymphocyte assays were not different between ocrelizumab and other DMTs.
While there is a paucity of data relating to MS, DMTs and acquired immunity to COVID-19 infection, there is evidence that the use of some DMTs in MS can attenuate the immune response to various viral and nonviral vaccines. A number of DMTs in common use in MS patients increase their risk for a number of infectious complications, including bacterial and nonbacterial upper and lower respiratory tract infections, herpes virus infections, cryptococcal meningitis, progressive multifocal leukoencephalopathy and reactivation of latent tuberculosis and hepatitis B infections. Therefore, clinicians must be mindful of the initiation and timing of vaccinations, as well as the selection of DMTs in particular patients, to mitigate the risk of opportunistic infections.
This is critical with respect to assessing the protective effect of COVID-19 vaccination during the pandemic, especially as public health measures against COVID-19, e.g., social distancing, mask wearing, work and school restrictions, have been relaxed for vaccinated persons. What is clear from some preliminary studies is that PWMS on particular DMTs have attenuated responses to COVID-19 vaccines. Furthermore, there are approximately a dozen ongoing studies assessing the impact of DMTs on COVID-19 vaccination. One such study looked at antibody levels to the COVID-19 spike protein after vaccination with BNT162b2 in patients on no treatment or high efficacy DMTs, e.g., fingolimod, cladribine, or ocrelizumab. Humoral immunity in patients on ocrelizumab was achieved in 22.7%; fingolimod 3.8%, and cladribine 100% 33.
The potential attenuation of immunity to COVID-19 vaccination in PWMS at present is an unresolved dilemma for patients and physicians. Of course, this applies to other patients as well, including those on immune suppressive treatments for cancer or rheumatological diseases. There are commercially available assays to measure COVID-19 spike protein antibodies, but what are physicians to tell patients who test negative for these antibodies after vaccination. Some MS colleagues take the position that the tests should not be ordered due to a lack of guidance as to how to use that information.
One possible way to mitigate this dilemma is to administer booster vaccinations. A number of clinical investigators in other medical specialties are testing this approach. Indeed, since the extent to which the current vaccines induce long-term immunity to COVID-19 ia unknoqn, this is a relevant issue for the general population as well. A small study of 33 adults showed that high levels of antibodies persisted for six months after vaccination with mRNA-1273.
A booster vaccine may be homologous (same vaccine) or heterologous (different vaccine) relative to the initial vaccine. Evidence from one mouse study indicates that the immune response is more robust from heterologous combinations of mRNA and DNA COVID-19 vaccines than homologous combinations, particularly in the induction of T cells, which is believed to be more important for long term immunity. Another rationale for the use of heterologous combinations is to administer one dose each of the combination, rather than a full series of the mRNA vaccine, to determine which strategy produces more robust immunity.
This study will attempt to address whether giving a heterologous dose of a booster vaccine will increase the chance of both antibody production and T lymphocyte activation in PWMS who do not initially show evidence of antibody reactivity.
Research Plan:
The research team will recruit PWMS who have completed vaccination against COVID-19 and test negative for COVID-19 spike protein antibodies using a commercial assay. Subjects will have baseline blood drawn for T and B lymphocyte subsets, quantitative immune globulins and COVID-19 spike protein antibodies. Women of child-bearing potential will have a urine pregnancy test. Baseline, demographic and disease specific variables will be collected.
Subjects will be randomized on a stratified basis to one of two treatment groups: Group 1 will receive a booster dose of a homologous vaccine and Group 2 a heterologous vaccine. Depending on the initial vaccine series received, this means Ad26.COV2.S if they originally received BNT162b2 or mRNA-1273 or vice versa.
Subjects will return to the clinic 4 to 6 weeks later to be retested for COVID-19 spike protein antibodies. Reactions to the booster vaccine and any potential adverse events will be recorded.
Visit 1:
* Clinical screening; review of clinical course; medications; body mass index; vital signs; physical exam, neurological exam; and urine pregnancy test (if applicable);
* Phlebotomy for B and T lymphocyte subsets, quantitative immune globulins and COVID-19 spike antibodies;
* Administration of vaccine, followed by monitoring for any adverse effects for 15 to 30 minutes.
Visit 2:
* Physical and neurological examination
* Change of medications, assessment of disease activity (including relapses), adverse events including an assessment of relationship to vaccination
* Phlebotomy for COVID-19 spike protein antibodies
Data Analysis:
* Spike protein antibody titers, quantitative immune globulins, B \& T cell subsets and COVID-specific T lymphocytes will be analyzed between Groups 1 \& 2 and within Groups 1 \& 2.
* DMT treatment, prior COVID-19 and/or vaccination history will be treated as covariates.
