Treating primary progressive multiple sclerosis patients with Ocrevus (ocrelizumab) led to a three-fold increase in the proportion of those showing no evidence of disease progression and no signs of inflammatory disease activity over more than two years of treatment, results of a Phase 3 trial show, and support new measures that might better capture disability in PPMS patients. The research, “Evaluation of No Evidence of Progression or Active Disease (NEPAD) in Patients With Primary Progressive Multiple Sclerosis in the ORATORIO Trial,” was published in the journal Annals of Neurology. Measuring disease progression in clinical trials and clinical practice requires reliable and comprehensible measures. Although widely used, the Expanded Disability Status Scale (EDSS, range 0-10) cannot fully capture changes in walking speed and hand or arm function, which are key determinants of overall disability in progressive forms of MS. No evidence of progression (NEP) is a newer measure that reflects the absence of disability progression, including upper limb function and walking speed. Maintaining NEP status means stable disease with no worsening in EDSS, in walking ability (assessed by the Timed 25-Foot Walk (T25FW) test, or the time it takes to walk 25 feet as quickly and safely as possible), and in upper limb function (assessed by the 9-Hole Peg Test (9HPT), a test of arm and hand dexterity). Patients with PPMS have less frequent signs of disease activity, which include relapses and brain lesions (assessed though magnetic resonance imaging or MRI). So scientists proposed a new measure — called “no evidence of progression or active disease” (NEPAD) — to evaluate both NEP and clinical and MRI measures of active disease. The researchers believe that NEPAD may represent a more sensitive and comprehensive measure of disease control in PPMS patients. The randomized, double-blind ORATORIO Phase 3 trial (NCT01194570) analyzed the efficacy and safety of Ocrevus — developed by Genentech, part of the Roche group — in 732 PPMS patients (age range 18–55). Results showed that Ocrevus treatment delayed the relative risk of disability progression by 25% compared to placebo, while also reducing the volume of chronic brain lesions and total brain volume loss. As a result, Ocrevus became the first therapy approved by the U.S. Food and Drug Administration and the European Commission for both PPMS and relapsing MS. Now, researchers assessed Ocrevus’ effect in PPMS patients included in the Roche-funded ORATORIO study using as trial goals changes in NEP and NEPAD. These people received either 600 mg of Ocrevus or placebo by intravenous (IV) infusion every six months for a minimum of 120 weeks (about 2.3 years). The trial’s main goal was time to onset of clinical disability progression (CDP) sustained for at least 12 weeks. CDP was defined as a 1.0 point or greater increase in EDSS score from a baseline (study start) score of 5.5 or less, or a 0.5-point increase from a baseline score greater than 5.5. NEP status, analyzed in 230 placebo- and 461 Ocrevus-treated patients, was defined as no evidence of CDP for 12 weeks, no 20% or more change in hand/arm function as measured by the 9HPT for 12 weeks, and no 20% or more change in walking ability as measured by the T25FW test for 12 weeks. "The 20% cut-off for progression on the T25FW test and the 9HPT has previously been shown to be a clinically meaningful magnitude of disease progression," the study noted. In turn, NEPAD — assessed in 234 placebo- and 465 Ocrevus-treated patients — included NEP, no brain MRI-measured disease activity, and no relapses. Relapses were defined as new or worsening neurological symptoms attributable to MS lasting longer than 24 hours and preceded by neurological stability for a minimum of 30 days. Brain MRI scans were conducted at baseline, and weeks 24, 48, and 120; new or enlarging T2 lesions and/or T1 enhancing lesions were considered evidence of MRI disease activity (T1 MRI imaging offers information about current disease activity by highlighting areas of active inflammation, while a T2 MRI image provides information about disease burden or lesion load). Overall, the majority of the PPMS patients analyzed experienced clinical disease progression or evidence of disease activity. From baseline to week 120, Ocrevus-treated patients who achieved NEP (42.7% of 461 people) or NEPAD (29.9% of 465)  — no disease activity or progression — were found to have lower T2 brain lesion volume and a lower EDSS score (lesser disability) compared to those with evidence of MS progression. They also had a slightly superior performance on the 9HPT and the T25FW test. Patients who reached NEPAD also showed fewer T1 lesions than patients with progressing or active disease. Compared to placebo treatment, the proportion of Ocrevus-treated PPMS patients maintaining NEP or NEPAD from baseline to week 120 was higher — for NEP, 42.7% versus 29.1% in the placebo group; for NEPAD, 29.9% versus 9.4% in the placebo group. These results showed that Ocrevus treatment increased the proportion of PPMS patients with NEPAD throughout the 120 weeks of the study by three-fold. “In conclusion, ocrelizumab (Ocrevus) increased the proportion of patients with PPMS with no evidence of progression and no clinical and subclinical disease activity compared with placebo,” the team wrote. “As such, NEPAD may represent a meaningful and comprehensive disease outcome in patients with PPMS.” However, data from ORATORIO's open-label extension and real-world data are needed to "determine whether NEPAD maintained throughout 120 weeks will translate into sustained NEPAD and enhanced protection against accrual of disability in patients with PPMS over the long term," the researchers concluded. Of note, five of the study’s 11 authors are employees and/or shareholders of Roche or Genentech.

Treatment with Ocrevus (ocrelizumab) is linked to a reduced immune response to vaccinations in patients with relapsing multiple sclerosis (MS), according to a Phase 3 trial. These results were recently presented at the 2018 American Academy of Neurology (AAN) Annual Meeting in Los Angeles in a presentation titled, “Effect of Ocrelizumab on Vaccine Responses in Patients With Multiple Sclerosis.” Genentech’s Ocrevus is an approved MS therapy that targets the CD20 protein located on the surface of B-cells, targeting the cells for destruction. B-cells are immune system cells involved, for example, in the production of antibodies necessary to fight off infection. At the AAN meeting, researchers reported that in MS patients, treatment with Ocrevus decreased the ability of B-cells to activate other immune cells, improving the rate of MS attacks. Penn Medicine neurologist Amit Bar-Or, MD, presented these findings, which showed that interactions between different classes of immune cells, such as B- and T-cells, promote MS attacks. Vaccination against infections is an important part of the management of patients with MS. So, in a second study (NCT02545868), researchers investigated the impact treatment with Ocrevus has on patient response to vaccines. They recruited 102 patients with relapsing MS and randomized them in two groups. In group A, 68 people received a single dose of 600 mg Ocrevus (administered into the blood); in group B, 34 patients received no disease-modifying therapy or interferon-beta. All patients were then administered vaccines for tetanus, seasonal flu, and pneumococcus. Patients in group A received the vaccines 12 weeks after they were treated with Ocrevus, while group B patients received the vaccines on day one. Researchers also tested patients’ response to a novel protein (an antigen) never "seen" by their immune system, called keyhole limpet hemocyanin (KLH) neoantigen. The vaccinations led to an immune system response in all patients, but the level of response in patients treated with Ocrevus was lower. A positive response to the tetanus vaccine at eight weeks after treatment was 23.9% in group A (Ocrevus) compared with 54.5% in group B (no treatment); the response to pneumococcus vaccination was 71.6% in group A and 100% in group B. After four weeks of treatment, the levels of antibodies against the different strains of the flu virus were lower in Ocrevus-treated patients than in the control group, ranging from 55.6% to 80.0% in the Ocrevus group compared with 75.0% to 97.0% in the controls. The immune response to the neoantigen KLH was also decreased in the Ocrevus group. "This study shows that while people with MS treated with ocrelizumab [Ocrevus] can still mount vaccine responses, it's not nearly as strong as prior to treatment," Bar-Or said in a press release. "While antibody responses were reduced in the ocrelizumab treated patients, they still responded to a certain level," he said. "This is valuable information in terms of seasonal vaccines such as the flu — it appears safe for patients taking ocrelizumab to get vaccinated and vaccination is likely to provide them with at least some protection from such infections." These findings correlate with standard guidelines that advise patients to undergo vaccinations six weeks before they start treatment with Ocrevus.

Autologous hematopoietic stem cell transplantation, also known as aHSCT, has been shown to be safe and highly effective to treat patients with "aggressive" multiple sclerosis. Tested in 19 patients, transplantation of stem cells was found to induce clinically meaningful improvements in disability. These findings were shared at the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, California. aHSCT uses a patient’s own healthy bone marrow stem cells, in combination with a much less aggressive chemotherapy and/or radiation regimen, to prepare the patient for the transplant. Previous studies have suggested that aHSCT is an effective strategy to treat patients with highly active relapsing-remitting MS (RRMS) who do not respond to available disease-modifying therapies (DMTs), and international guidelines advocate for its use in patients with "aggressive" MS. To further demonstrate the potential of aHSCT as a treatment for "aggressive" MS, a research team evaluated its safety and effectiveness in MS patients who had not been treated previously with DMTs. A total of 19 patients were treated across several clinical centers: seven patients were from Sheffield, U.K., seven from Uppsala, Sweden, four from Ottawa, Canada, and one patient was from Florence, Italy. All patients received aHSCT between May 2004 and May 2017. In addition to aHSCT, patients were treated with BEAM (carmustine, etoposide, cytarabine, melphalan) chemotherapy plus antithymocyte globulin (ATG) to reduce transplant rejection, or with Cytoxan (cyclophosphamide) with ATG, or the triple combination of Cytoxan, ATG, plus busulfan as conditioning regimens. Patients had a median age of 33 years at diagnosis and received the aHSCT by a median time of nine years after symptom onset. They had a median disability score of 6.5 before the treatment, as determined by the Expanded Disability Status Scale (EDSS). After a median follow-up period of 30 months, patients had a median EDSS score of 2.0, which represented a median improvement of 2 points (the higher the score, the worse the patient's disability level). None of the patients had clinical relapse following the transplant of stem cells. Only three patients developed new brain lesions detectable by magnetic resonance imaging (MRI) at the first six-month follow-up evaluation, but no additional new lesions were detected in the following scans. The adverse effects reported during the study were comparable to those previously observed in similar treatments. No deaths related to the treatment were reported. Based on these preliminary results, the researchers concluded that aHSCT is “safe and highly effective in inducing rapid and sustain remission” in highly active MS, and "was associated with a significant improvement of [patient’s] level of disability.” “aHSCT should be considered as first line therapy in patients with ‘aggressive’ MS,” the team concluded. Another study presented at the AAN 2018 meeting further supports these findings, demonstrating the superior effectiveness of aHSCT over conventional DMTs for RRMS.
