32388451 Development of PML or other serious opportunistic infections during treatment with natalizumab forces to consider whether de-risking strategies are needed in this particular context and how to manage a high-efficacy treatment. […] In this paper we report on a patient treated with natalizumab for relapsing MS who developed COVID-19 and recovered in a few days without complications. […] After recovery natalizumab has been administered in the window of the extended interval dosing (EID), without reporting any worsening or new symptoms.
32531754 Natalizumab, approved for Multiple Sclerosis (MS) treatment, acts blocking α4-integrin. […] We report a MS patient treated with natalizumab who develops COVID-19, with excellent recovery and repeated negative results in 5 consecutive microbiological studies. […] We postulate this may be due to the blockade of integrins induced by natalizumab.
32590314 Platform therapies, dimethyl-fumarate and natalizumab are considered safe options to initiate in naive patients. decision-making about MS and NMOSD patients has become even more complex in order to adapt to the COVID-19 pandemic.
32609290 We focus on how to 1) reduce COVID-19 infection risk, such as social distancing, telemedicine, and wider interval between laboratory testing/imaging; 2) manage relapses, such as avoiding treatment of mild relapse and using oral steroids; 3) manage disease-modifying therapies, such as preference for drugs associated with lower infection risk (interferons, glatiramer, teriflunomide, and natalizumab) and extended-interval dosing of natalizumab, when safe; 4) individualize the chosen MS induction-therapy (anti-CD20 monoclonal antibodies, alemtuzumab, and cladribine); 5) manage NMOSD preventive therapies, including initial therapy selection and current treatment maintenance; 6) manage MS/NMOSD patients infected with COVID-19.
32629402 The cases involved a combination of relapsing and progressive MS phenotypes treated with a range of DMT (5 anti CD20 therapy, 4 cladribine, 4 fingolimod, 4 injectables, 3 alemtuzumab, 2 dimethyl fumarate, 2 untreated, 1 teriflunomide, 1 natalizumab).
32638107 Changes in DMTs were most common with the high-efficacy therapies alemtuzumab, cladribine, ocrelizumab, rituximab, and natalizumab. 35% made no changes to DMT prescribing. 98% expressed worry about their patients contracting COVID-19 and 78% expressed the same degree of worry about themselves. > 50% believed high-efficacy DMTs prolong viral shedding of SARS-CoV-2 and that B-cell therapies might prevent protective vaccine effects.
32769063 Vaccine responses were reduced to varying degrees in those treated with glatiramer acetate, teriflunomide, sphingosine-1-phosphate receptor modulators, and natalizumab.
32780300 Immune-modulating therapies such as the fumerates, sphinogosine-1P modulators, and natalizumab may be anecdotally preferred over cell-depleting immunosuppressants during the pandemic from the immune profile standpoint.
32850133 We report a fatal case of COVID-19 in a 51-year-old African American woman with multiple sclerosis on natalizumab. […] She had multiple risk factors for severe COVID-19 disease including race, obesity, hypertension, and elevated inflammatory markers, but the contribution of natalizumab to her poor outcome remains unknown. […] We consider whether altered dynamics of peripheral immune cells in the context of natalizumab treatment could worsen the cytokine storm syndrome associated with severe COVID-19. […] We discuss extended interval dosing as a risk-reduction strategy for multiple sclerosis patients on natalizumab, and the use of interleukin-6 inhibitors in such patients who contract COVID-19.
32957057 We aimed to evaluate patient perspectives regarding the use of Natalizumab and anti-CD20 therapies (Rituximab and Ocrelizumab) in the context of the COVID-19 pandemic. cross-sectional study conducted via voluntary survey filled in by patients with MS and related disorders receiving their infusional treatment in one MS centre in Australia, exploring their concerns regarding their therapy, their therapy and COVID-19, precautions undertaken in response to the pandemic, and factors impacting their decision-making. 170 patients completed the survey. […] Of patients on Natalizumab, the majority had either no or mild concern regarding their DMT and COVID-19, and of patients on B-cell depleting therapies, again, the majority had no or mild concern, though a slightly higher proportion had a moderate level of concern.
33061471 , dimethyl fumarate (DMF), monomethyl fumarate (MMF), natalizumab, ocrelizumab, and IFN-β, among others have been previously described to increase the biological activities of NK cells especially their cytolytic potential as reported by upregulation of CD107a, and the release of perforin and granzymes.
33321356 To analyse the rate of infusion related reactions and patient experience of rapid infusions of natalizumab and ocrelizumab. […] Patients with prior exposure to at least three natalizumab or two 300mg ocrelizumab infusions were approved for rapid protocols. […] We analysed 269 rapid natalizumab infusions and 100 rapid ocrelizumab infusions. […] Infusion related reactions during the natalizumab or ocrelizumab infusions occurred in two patients (1.52%) and eight patients (8%), respectively.
33361386 PML is an infection of the CNS caused by JC virus (JCV), which commonly occurs during treatment with the therapeutic monoclonal antibody natalizumab. […] Based on pathogenic lessons learned from PML under natalizumab therapy, we suggest the incorporation of functional assays that determine neutralizing properties of SARS-CoV-2-specific antibodies.
33584093 Besides, the potential neurotropism of the acute respiratory distress syndrome corona virus-2 (SARS-CoV-2), which is still not established, may raise concerns about the use of certain disease modifying therapies namely natalizumab.
