ICYMI Multiple Sclerosis

NEW ORLEANS—The safety profile of ocrelizumab in ongoing open-label extension studies in relapsing multiple sclerosis (MS) and primary progressive MS is generally consistent with that observed in controlled clinical trials, according to a report presented at the 31st Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC). “A slight increase in the rate of serious infections was observed in patients with relapsing MS beyond two years, but the rates remained low,” reported Ludwig Kappos, MD, Chair of Neurology at University Hospital Basel in Switzerland, and colleagues. “This was not observed in patients with primary progressive MS, and additional exposure data are needed to determine if the risk increases with further dosing,” the researchers said. “Incidence rates of malignancies and breast cancer observed with ocrelizumab treatment in MS remain within the range of epidemiologic background data.”

The safety and efficacy of ocrelizumab previously have been characterized in a phase II study in patients with relapsing-remitting MS and in phase III studies in patients with relapsing MS (OPERA I and OPERA II) and in patients with primary progressive MS (ORATORIO). Results from these trials showed that ocrelizumab reduced clinical and MRI evidence of disease activity, compared with placebo and interferon beta-1a. The most common adverse events associated with ocrelizumab during the double-blind periods of the phase III trials included infusion-related reactions, nasopharyngitis, upper respiratory tract infections, headache, and urinary tract infections. During the double-blind treatment period in the phase III trials in relapsing MS, serious adverse events, serious infections, and malignancies were reported in 6.9%, 1.3%, and 0.5% of ocrelizumab-treated patients, respectively (vs 8.7%, 2.9%, and 0.2% of patients treated with interferon beta-1a). In the phase III trial in primary progressive MS, these events were reported in 20.4%, 6.2%, and 2.3% of ocrelizumab-treated patients (vs 22.2%, 5.9%, and 0.8% of patients who received placebo). Across studies, few patients who received ocrelizumab (in the range of 2% to 4%) had adverse event–related treatment withdrawals.

At the CMSC annual meeting, data from controlled and open-label extension periods of the clinical trials of ocrelizumab in relapsing MS and primary progressive MS were presented.

Upon completion of a double-blind treatment period, patients from all studies were eligible to enter a long-term open-label extension in which they received ocrelizumab treatment. Safety analyses were based on integrated data from the phase II and phase III studies. The primary analysis was based on the clinical cutoff dates of the individual studies (phase II, January 22, 2015; OPERA I, April 2, 2015; OPERA II, May 12, 2015; ORATORIO, July 24, 2015). The present updated analysis includes all patients who received one or more dose of ocrelizumab during the controlled or open-label periods of the phase II and phase III studies (ie, the ocrelizumab all-exposure population) as of January 20, 2016. Additional data cutoffs of June 30, 2016, and September 15, 2016, were presented for malignancies to demonstrate changes with increasing ocrelizumab exposure.

The ocrelizumab all-exposure group included 2,279 patients. Patients’ mean age was 40.1, and 61.3% were female. Time since MS symptom onset was 6.67 years, and time since MS diagnosis was 3.66 years.

Overall Adverse Events

As of January 20, 2016, the majority (81%) of patients who received ocrelizumab experienced at least one adverse event, corresponding to a rate of 242 events per 100 patient-years. The most common adverse events included nasopharyngitis, upper respiratory tract infection, urinary tract infection, infusion-related reactions, and headache. Serious adverse events were reported in 12% of patients, corresponding to 6.97 events per 100 patient-years, and most commonly included infections. Treatment withdrawal because of an adverse event occurred in 3.3% of patients (rate, 1.40 per 100 patient-years) and primarily included infusion-related reactions (0.9%) and events coded as neoplasms (0.6%) or infections (0.4%).

Infections

As of January 20, 2016, 56.9% of the ocrelizumab all-exposure population reported one or more infection with ocrelizumab, corresponding to a rate of 73.6 per 100 patient-years. “These findings are consistent with the 75.6 rate observed at the primary analysis cutoff date,” the researchers reported. Infections were reported at the highest rate following the first dose and declined with subsequent dosing. Infections reported in 5% or more of patients included nasopharyngitis, upper respiratory tract infection, urinary tract infection, bronchitis, and influenza. In the ocrelizumab all-exposure population, the rate per 100 patient-years of serious infections (1.80) as of January 20, 2016, was comparable with the rate at the primary analysis cutoff date (1.74). Data for the pooled relapsing MS population showed a slight increase in the rate per 100 patient-years of serious infections (1.45) as of January 20, 2016, compared with the rate at the primary analysis cutoff date (1.08); “however, rates remained low, and further exposure is needed to make any interpretation,” the researchers said.

Among patients with primary progressive MS, the rate per 100 patient-years of serious infections remained stable (2.74) as of January 20, 2016, compared with the rate at the primary analysis cutoff date (2.97). The most common serious infection reported was pneumonia. No infections were identified as opportunistic in nature.

Malignancies

In the MS clinical trial program, an imbalance in the crude incidence of malignancies was observed between the ocrelizumab- and comparator-treated patients, which was associated with a cluster of breast cancer events in the ocrelizumab group. Over time, the crude incidence rate of malignancy per 100 patient-years in the ocrelizumab all-exposure population fluctuated but remained within the epidemiologic range of patients with MS. An observed change in the crude incidence rate of malignancy from June to September is attributed to the crude incidence rate of non-melanoma skin cancer, which increased from 0.090 at the primary analysis cutoff date to 0.145 at the September 15, 2016, data cutoff, due to six new cases of basal cell carcinoma. The crude incidence rate of breast cancer remained stable through the September 15, 2016, data cutoff.

More Recent Developments

In late May 2017, Genentech, the maker of ocrelizumab, notified physicians of the first case of progressive multifocal leukoencephalopathy (PML) in a patient taking ocrelizumab. The case occurred in a JCV-positive patient in Germany who stopped taking natalizumab in February after being on the drug for three years, and received the first dose of ocrelizumab in April. It is unclear whether the PML stemmed from the prior natalizumab treatment or if the switch to ocrelizumab played a role.

NEW ORLEANS—A single bout of treadmill walking might affect cognitive processing to a greater degree than stationary cycling, particularly among those with multiple sclerosis (MS) who demonstrate low aerobic fitness, according to a report presented at the 31st Annual Meeting of the Consortium of MS Centers. "This [finding] highlights the importance of targeting those with low aerobic fitness in treadmill walking exercise training interventions for improving cognition in persons with MS, as improving aerobic fitness may be beneficial for reducing MS-related cognitive-motor interference," said Brian M. Sandroff, PhD, of the Kessler Foundation in West Orange, New Jersey, and colleagues.

The mechanisms by which treadmill walking improves cognition in patients with MS are not well understood. Researchers have hypothesized that treadmill walking is essentially a complex cognitive task that requires more attentional resources than other modalities of aerobic exercise (eg, cycle ergometry), and that repeated exposure trains the person in cognitive-motor processing. If this hypothesis is true, then patients with MS should demonstrate worse cognitive performance during treadmill walking than during cycle ergometry, as more attentional resources would presumably be devoted to walking on a treadmill than to cycling on a stationary bicycle. Furthermore, it is unknown whether better aerobic fitness attenuates such cognitive-motor interference in patients with MS.  

Dr. Sandroff and colleagues conducted a pilot study to examine cognitive performance before and during acute bouts of treadmill walking, stationary cycling, and seated quiet rest in 12 fully ambulatory patients with MS with high or low aerobic fitness using a within-subjects, repeated-measures design.  

Participants underwent a baseline incremental exercise test to exhaustion for measurement of aerobic fitness (ie, VO_2peak). Participants further completed three experimental conditions that consisted of 20 minutes of moderate- to vigorous-intensity treadmill walking exercise, moderate- to vigorous-intensity cycle ergometer exercise, and seated quiet rest in a randomized, counterbalanced order. Participants underwent the three-second Paced Auditory Serial Addition Test (PASAT) as a measure of cognitive performance prior to and during each condition.  

Overall, decreases in PASAT performance during treadmill walking were not larger than those during cycle ergometry, relative to quiet rest. However, decreases in PASAT performance were larger for those with lower aerobic fitness during treadmill walking than during cycle ergometry, compared with quiet rest.

A Retrospective Chart Review

Ms. Vollmer and colleagues conducted a retrospective study to compare the discontinuation rates and efficacy of fingolimod and dimethyl fumarate to those of natalizumab. In a retrospective chart review, they identified patients with multiple sclerosis (MS) who presented to the Rocky Mountain MS Center in Aurora, Colorado. Eligible participants initiated drug therapy between January 2010 and October 2013. Patients who initiated natalizumab had to be negative for the John Cunningham virus (JCV) at baseline. Ms. Vollmer and colleagues retrospectively collected clinician-recorded data.

The study’s primary outcome was discontinuation at 24 months. Secondary outcomes included reasons for discontinuation, relapse activity, MRI activity, and a composite disease activity measure that comprised clinical relapse, contrast enhancement, and new T2 lesions on follow-up MRI. Ms. Vollmer and colleagues identified 1,302 patients who initiated insurance paperwork for natalizumab. To reduce the size of this sample, they randomly selected 800 patients, of whom 270 met the inclusion criteria. In all, 440 participants initiated paperwork for fingolimod, of whom 271 met the inclusion criteria. For dimethyl fumarate, the researchers found 592 participants who initiated the paperwork, and 342 met the inclusion criteria.

Patients receiving natalizumab were significantly younger (mean age, 39.8) than patients receiving fingolimod (42.5) or dimethyl fumarate (45.8). Furthermore, patients treated with natalizumab were more likely to be female (77.8%) than patients treated with fingolimod (72.0%) or dimethyl fumarate (69.6%). Patients receiving natalizumab also were more likely to have contrast enhancement on baseline MRI (31.2%) than were participants receiving fingolimod (24.6%) or dimethyl fumarate (14.6%). Mean disease duration was approximately 12 years for all groups.

Discontinuation and Disease Activity

The rate of discontinuation was similar for natalizumab (33.3%) and fingolimod (34.3%), but the researchers observed a significant difference between natalizumab and dimethyl fumarate (47.1%). Disease activity and adverse events were the most common reasons for discontinuation of fingolimod and dimethyl fumarate, and JCV positivity was the most common reason for discontinuation of natalizumab. Of the seven participants who discontinued natalizumab because of disease activity, five had neutralizing antibodies. Of the 20 patients who discontinued natalizumab because of adverse events, nine had rashes during infusion, eight of whom tested positive for neutralizing antibodies.

Ms. Vollmer and colleagues found no significant difference between natalizumab and fingolimod in the rate of patients with a clinical relapse (5.6% and 8.9%, respectively), but they observed a significant difference between dimethyl fumarate (12.9%) and natalizumab for this outcome. Contrast enhancement was less common among patients receiving natalizumab (6.6%), compared with fingolimod (13.1%), but there was no significant difference between natalizumab and dimethyl fumarate (10.0%).

The rate of new T2 lesions was lower with natalizumab (21.4%), compared with fingolimod (35.0%) and dimethyl fumarate (31.5%). Similarly, the composite disease activity measure was less common with natalizumab (20.7%), compared with fingolimod (34.7%) and dimethyl fumarate (33.6%). Data adjustments indicated that discontinuation was equally likely among patients receiving fingolimod and those receiving natalizumab. Patients receiving dimethyl fumarate, however, were approximately twice as likely to discontinue treatment, compared with patients receiving natalizumab.

Furthermore, patients receiving fingolimod were approximately twice as likely to discontinue treatment because of adverse events, compared with patients receiving natalizumab. Patients treated with dimethyl fumarate were approximately four times as likely to discontinue because of adverse events, compared with patients treated with natalizumab. In addition, patients were approximately twice as likely to have disease activity on fingolimod or dimethyl fumarate, compared with natalizumab.

Mean disease duration was approximately 12 years for all groups.

Discontinuation and Disease Activity

The rate of discontinuation was similar for natalizumab (33.3%) and fingolimod (34.3%), but the researchers observed a significant difference between natalizumab and dimethyl fumarate (47.1%). Disease activity and adverse events were the most common reasons for discontinuation of fingolimod and dimethyl fumarate, and JCV positivity was the most common reason for discontinuation of natalizumab. Of the seven participants who discontinued natalizumab because of disease activity, five had neutralizing antibodies. Of the 20 patients who discontinued natalizumab because of adverse events, nine had rashes during infusion, eight of whom tested positive for neutralizing antibodies.

Ms. Vollmer and colleagues found no significant difference between natalizumab and fingolimod in the rate of patients with a clinical relapse (5.6% and 8.9%, respectively), but they observed a significant difference between dimethyl fumarate (12.9%) and natalizumab for this outcome. Contrast enhancement was less common among patients receiving natalizumab (6.6%), compared with fingolimod (13.1%), but there was no significant difference between natalizumab and dimethyl fumarate (10.0%).

The rate of new T2 lesions was lower with natalizumab (21.4%), compared with fingolimod (35.0%) and dimethyl fumarate (31.5%). Similarly, the composite disease activity measure was less common with natalizumab (20.7%), compared with fingolimod (34.7%) and dimethyl fumarate (33.6%). Data adjustments indicated that discontinuation was equally likely among patients receiving fingolimod and those receiving natalizumab. Patients receiving dimethyl fumarate, however, were approximately twice as likely to discontinue treatment, compared with patients receiving natalizumab.

Furthermore, patients receiving fingolimod were approximately twice as likely to discontinue treatment because of adverse events, compared with patients receiving natalizumab. Patients treated with dimethyl fumarate were approximately four times as likely to discontinue because of adverse events, compared with patients treated with natalizumab. In addition, patients were approximately twice as likely to have disease activity on fingolimod or dimethyl fumarate, compared with natalizumab.

A Retrospective Chart Review

Ms. Vollmer and colleagues conducted a retrospective study to compare the discontinuation rates and efficacy of fingolimod and dimethyl fumarate to those of natalizumab. In a retrospective chart review, they identified patients with multiple sclerosis (MS) who presented to the Rocky Mountain MS Center in Aurora, Colorado. Eligible participants initiated drug therapy between January 2010 and October 2013. Patients who initiated natalizumab had to be negative for the John Cunningham virus (JCV) at baseline. Ms. Vollmer and colleagues retrospectively collected clinician-recorded data.

The study’s primary outcome was discontinuation at 24 months. Secondary outcomes included reasons for discontinuation, relapse activity, MRI activity, and a composite disease activity measure that comprised clinical relapse, contrast enhancement, and new T2 lesions on follow-up MRI. Ms. Vollmer and colleagues identified 1,302 patients who initiated insurance paperwork for natalizumab. To reduce the size of this sample, they randomly selected 800 patients, of whom 270 met the inclusion criteria. In all, 440 participants initiated paperwork for fingolimod, of whom 271 met the inclusion criteria. For dimethyl fumarate, the researchers found 592 participants who initiated the paperwork, and 342 met the inclusion criteria.

Patients receiving natalizumab were significantly younger (mean age, 39.8) than patients receiving fingolimod (42.5) or dimethyl fumarate (45.8). Furthermore, patients treated with natalizumab were more likely to be female (77.8%) than patients treated with fingolimod (72.0%) or dimethyl fumarate (69.6%). Patients receiving natalizumab also were more likely to have contrast enhancement on baseline MRI (31.2%) than were participants receiving fingolimod (24.6%) or dimethyl fumarate (14.6%).

NEW ORLEANS—Discontinuation of disease-modifying treatments (DMTs) may be considered for patients with secondary progressive multiple sclerosis (SPMS) age 55 or older with ongoing progression and no clinical relapses or new MRI lesions consistent with MS in the previous five years, according to research presented at the 31st Annual Meeting of the Consortium of MS Centers. Data from the study also suggest that it is reasonable to consider discontinuing DMTs for patients in the same age range with stable relapsing remitting (RR) MS who have had no clinical relapses or new MRI lesions consistent with MS in the previous five years.

Although DMTs can reduce relapse rates and progression of disability early in the course of RRMS, it remains unknown whether these treatments maintain efficacy late in the course of RRMS, in SPMS, or in older patients. Considerations for discontinuing treatment include potential inefficacy of DMTs and adverse effects in this cohort, said the authors.  

Devyn Parsons, a medical student at the University of British Columbia in Vancouver, Canada, working with Anthony Traboulsee, MD, and colleagues, conducted a systematic search to examine literature relevant to the discontinuation of DMTs and to provide guidance about when DMTs may be discontinued. The investigators used the keywords “multiple sclerosis,” “disease modifying treatments,” “treatment withdrawal,” “stopping medication,” and “medication withdrawal” to search PubMed, Embase, and the Cochrane Database of Systematic Reviews. The search included articles up to June 2016 and was limited to English-language publications. 

The review yielded what Ms. Parsons described as a “paucity of information.” The investigators found evidence that disease activity in RRMS declined with increasing age and longer disease duration. Some observational studies suggested that older patients who continuously receive DMT and are free of disease activity for several years might be good candidates for discontinuation of DMTs. Since DMTs are associated with adverse events that may affect quality of life or pose serious safety risks, it is important to consider patient preference, said the authors. 

Safety monitoring following discontinuation of DMTs should include annual clinical assessment and annual brain MRIs for two to five years, with consideration of reinitiation of DMTs if evidence of new clinical relapse emerges or more than two new MRI lesions consistent with MS appear, said the researchers.

This study was supported by Sanofi Genzyme.

NEW ORLEANS – Multiple sclerosis has little to no impact on the ability to conceive, on pregnancy, or on fetal status, according to Patricia K. Coyle, MD.

“That’s very reassuring,” Dr. Coyle said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “We don’t see an increase in birth defects just because the mother has MS. There is no consistent increase in abortions, ectopic pregnancies, or assisted vaginal/cesarean deliveries.”

Dr. Coyle, director of the MS Comprehensive Care Center at Stony Brook (N.Y.) University Medical Center, said that the most dramatic changes for pregnant patients with MS occur in the final trimester and mainly involve rising levels of multiple hormones: estrogens, cortisol, progesterone, norepinephrine, and 1,25-dihydroxyvitamin D, which increase late in pregnancy, then rapidly drop off postpartum. This has led to the evaluation of sex hormone therapy for MS.

The impact of other pregnancy factors on MS disease activity remains unknown. One is microchimerism, a maternal-fetal exchange of cells and DNA. “These cells can last for a long time; you can find them in the blood, as well as in the [central nervous system],” Dr. Coyle said. “It’s been reported that fetal microchimerism may be increased in immune-mediated diseases like MS, but we really don’t have a lot of good data.”

Counseling tips

She went on to share counseling tips for MS patients of childbearing age, including the fact that some studies report slightly smaller babies born to mothers with MS, while others have not found that association. “This is a question mark, but it doesn’t seem to be a major issue,” she said. One thing you can tell patients for certain is that MS is not inherited. “There are well over 230 genes linked to MS, so there’s a genetic enrichment that can make somebody vulnerable to MS, but there’s no gene that passes on MS,” Dr. Coyle said. “The risk is slightly higher for a first-degree relative, so when a parent has MS, the risk for the child is in the range of 2% to 2.5%, compared with the expected 0.13% in the general population. But there’s a slightly higher risk when you’re a sibling than when you’re a parent – 2.7% – which is speaking to environmental factors having an important impact on genes.”

Controversial data exist as to whether a maternal deficiency in vitamin D poses a risk of MS in the offspring. Dr. Coyle makes it a point to “normalize” vitamin D levels in pregnant MS patients, particularly in white patients. “You’d want to have them on prenatal vitamins and folic acid and tell them not to smoke, to limit their alcohol use, and advise them to have good sleep hygiene.”

Dr. Coyle, vice chair of clinical affairs at Stony Brook University Medical Center, said that up until the 1950s, physicians advised women with MS against having children. “They were told not to get pregnant or to have an abortion, because it was thought to make MS worse,” she said. “It turns out that was fiction. That was completely wrong. Pregnancy has no negative effect on long-term MS prognosis. It may have long-term benefits for relapsing MS, but there are not enough data to comment on its impact on progressive MS. Pregnancy makes it less likely that someone will develop a clinically isolated syndrome, but it may increase the radiologically isolated syndrome risk for clinical attack. That’s based on 7 pregnant patients out of a cohort of 60, so we need further data to explain that.”
 

Disease-modifying therapies

When it comes to washouts of disease-modifying therapies (DMTs), no one-size-fits-all approach exists. Interferon betas and glatiramer acetate have more than 1,000 pregnancy exposures that yield no evidence for teratogenicity or negative fetal impact. No washout is needed prior to pregnancy. “These agents can be used during pregnancy and breastfeeding,” she said.

The other DMTs paint a somewhat different picture. “There is insufficient pregnancy exposure to the three available oral DMTs to comment definitively on their safety, but there is no clear human teratogenicity to date,” Dr. Coyle said. The conventional washout for fingolimod is 8 weeks. In Dr. Coyle’s opinion, no washout is required with dimethyl fumarate. “The half-life is 40 minutes. There are no good signs of issues. For teriflunomide, it can hang around in individuals for 18-24 months. You should go through an accelerated elimination procedure with oral cholestyramine 8 mg three times a day for 11 days until blood level of the agent is less than 0.02 mcg/mL. Avoid all the orals with breastfeeding.”

Monoclonal antibodies – another form of DMTs – lack sufficient pregnancy exposures to merit comment on safety, but they should not be used during breastfeeding. Natalizumab is a humanized IgG4 antibody that crosses the placenta. “This has been used in several dozen pregnancies because the patients got so bad when they were taken off that it required reinstituting natalizumab even though they were pregnant,” Dr. Coyle said. “Human pregnancy exposures have been associated with transient hematologic issues in the newborn, including anemia, thrombocytopenia, and pancytopenia.” Data indicate that the rate of spontaneous abortion among pregnant women treated with natalizumab was 9%, the rate of major birth defects was 5.05%, and no malformation pattern was observed. The drug is detected in human breast milk and has a half-life of 11 days.

Alemtuzumab is a humanized IgG1 monoclonal antibody that crosses the placenta. The half-life elimination is about 14 days. In transgenic mice, giving alemtuzumab during organogenesis was found to be embryolethal. In human pregnancy, hypothyroidism is a concern. “The recommendation has been to wait 4 months after the last treatment before you try to become pregnant. Alemtuzumab is considered a two-cycle treatment. You don’t get the maximum benefit after the first cycle of 5 days. The complete treatment is the second cycle 3 days.”

Daclizumab, another humanized IgG1 monoclonal antibody, also crosses the placenta. Monkey exposure during gestation led to embryofetal death and decreased fetal growth, “but this was at greater than 30 times the human dose,” she said. “It was found to be excreted in monkey breast milk and the half-life is 21 days.” In humans, there have been 36 exposed women who had 38 pregnancies and 20 live births. The rate of spontaneous abortions/miscarriages was 11%, there were eight elective terminations, two ectopic pregnancies, and one congenital heart defect. “This is very limited data, but nothing that would raise the level of concern,” Dr. Coyle said.

Ocrelizumab, another humanized IgG1 monoclonal antibody, was approved by the Food and Drug Administration in March 2017. Prior studies of anti-CD20 antibodies in human pregnancy noted transient lymphocytopenia and peripheral B cell depletion in the newborns. In studies of pregnant monkeys that used 2 and 10 times human doses during organogenesis, it was associated with B cell depletion in spleen/lymph nodes, Dr. Coyle said. “During organogenesis and throughout the neonatal period, treatment could be associated with perinatal death, some associated with bacterial infection; glomerulonephropathy with inflammation; a decrease in circulating B cells, a decrease in testicular weight, and bone marrow lymphoid follicle formation.” Ocrelizumab is excreted in monkey breast milk and the prescription label suggests a 6-month delay in pregnancy. The drug’s half-life is 26 days.

Dr. Coyle reported that she has served as a consultant for Accordant, Acorda, Bayer, Biogen, Celgene, Genentech/Roche, Genzyme/Sanofi, Novartis, Serono, and Teva. She has also received research support from Actelion, Alkermes, Genentech/Roche, MedDay, the National Institute of Neurological Disorders and Stroke, and Novartis.

In human pregnancy, hypothyroidism is a concern. “The recommendation has been to wait 4 months after the last treatment before you try to become pregnant. Alemtuzumab is considered a two-cycle treatment. You don’t get the maximum benefit after the first cycle of 5 days. The complete treatment is the second cycle 3 days.”

Daclizumab, another humanized IgG1 monoclonal antibody, also crosses the placenta. Monkey exposure during gestation led to embryofetal death and decreased fetal growth, “but this was at greater than 30 times the human dose,” she said. “It was found to be excreted in monkey breast milk and the half-life is 21 days.” In humans, there have been 36 exposed women who had 38 pregnancies and 20 live births. The rate of spontaneous abortions/miscarriages was 11%, there were eight elective terminations, two ectopic pregnancies, and one congenital heart defect. “This is very limited data, but nothing that would raise the level of concern,” Dr. Coyle said.

Ocrelizumab, another humanized IgG1 monoclonal antibody, was approved by the Food and Drug Administration in March 2017. Prior studies of anti-CD20 antibodies in human pregnancy noted transient lymphocytopenia and peripheral B cell depletion in the newborns. In studies of pregnant monkeys that used 2 and 10 times human doses during organogenesis, it was associated with B cell depletion in spleen/lymph nodes, Dr. Coyle said. “During organogenesis and throughout the neonatal period, treatment could be associated with perinatal death, some associated with bacterial infection; glomerulonephropathy with inflammation; a decrease in circulating B cells, a decrease in testicular weight, and bone marrow lymphoid follicle formation.” Ocrelizumab is excreted in monkey breast milk and the prescription label suggests a 6-month delay in pregnancy. The drug’s half-life is 26 days.

Dr. Coyle reported that she has served as a consultant for Accordant, Acorda, Bayer, Biogen, Celgene, Genentech/Roche, Genzyme/Sanofi, Novartis, Serono, and Teva. She has also received research support from Actelion, Alkermes, Genentech/Roche, MedDay, the National Institute of Neurological Disorders and Stroke, and Novartis.

NEW ORLEANS – Data from the ocrelizumab clinical development program gives clinicians a first look at pregnancy outcomes after exposure to the drug, but the small size limits the ability to draw firm conclusions.

In the United States, prescribing information for ocrelizumab states that women of childbearing potential should use contraception while receiving ocrelizumab and for 6 months after the last infusion. At the annual meeting of the Consortium of Multiple Sclerosis Centers, researchers led by Sibyl Wray, MD, set out to assess the pregnancy, fetal, neonatal and infant outcomes in patients who became pregnant during ocrelizumab trials in MS, rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) through Sept. 15, 2015.

MS data

Of the 15 pregnancies in the MS trials, three involved the delivery of full term, healthy newborns. In one case, the last ocrelizumab infusion was given 28 months before conception. In the second case, an infusion was given 20 weeks before conception, and a further infusion was given 17 days after conception. In the third case, the last ocrelizumab infusion was given 26.5 weeks before conception.

One live term birth occurred with an abnormal finding. In this case, the last infusion of ocrelizumab was 23 weeks prior to the last menstrual period or about 6 months prior to conception. The embryo/fetus was not exposed to the drug in utero. The researchers also found that seven elective terminations occurred among MS patients and that four pregnancies were ongoing at the time of this report.

“We have to be cautious because we don’t have enough data yet to know, but it’s encouraging to see that, if you follow the guidelines, the patient population and the newborns seem to be healthy in these exposed individuals,” Dr. Wray said.

RA data

Data from the RA clinical trials revealed 22 pregnancies in 21 patients exposed to ocrelizumab. Of these, eight pregnancies resulted in healthy term babies; four resulted in live births with abnormal findings (structural malformation, growth abnormality) or preterm birth; and eight pregnancies in seven women resulted in spontaneous abortion (one patient experienced a spontaneous abortion on two occasions), missed abortion, or an embryonic pregnancy. One pregnancy was lost to follow-up and another resulted in elective termination.

SLE data

During the SLE trials, 11 pregnancies occurred in 10 patients. Three pregnancies in two women resulted in healthy term babies. Three other pregnancies resulted in live births with an abnormal finding (structural malformation, functional deficit, growth abnormality) and/or preterm birth. Two pregnancies resulted in spontaneous/missed abortion. One pregnancy resulted in fetal death at 7.5 months’ gestation secondary to fatal pulmonary embolism in the mother; one pregnancy resulted in elective termination; and one pregnancy resulted in a healthy baby born at an unknown gestational week.

Dr. Wray emphasized that the small numbers of patients studied make it difficult to draw conclusions about pregnancy outcomes following ocrelizumab in patients with MS and other autoimmune diseases. “We need to pay attention to the half-life of this drug, the time it takes to clear, and how to plan pregnancies around that,” she said. She noted that pregnancy outcomes in ongoing ocrelizumab studies and postmarketing experiences will continue to be collected and assessed.

The study was funded by Roche, Basel, Switzerland. Dr. Wray reported that she has received honoraria and/or research funding from Actelion, Alkermes, Biogen, Celgene, EMD Serono, Genentech/Roche, Genzyme/Sanofi, Novartis, and TG Therapeutics.

NEW ORLEANS – Changes are coming to the current McDonald Criteria for diagnosing multiple sclerosis, primarily because of advances in the understanding of MS since the criteria were last updated in 2010.

Such advances include the availability of new data regarding the relationship between MS and other spectrum disorders and data concerning the performance of the 2010 McDonald Criteria in several patient populations, according to Jeffrey A. Cohen, MD, who cochaired the effort known as the International Panel on Diagnosis of Multiple Sclerosis. “There also were new data concerning the utility of cerebrospinal fluid evaluation and increasing recognition that the role of cerebrospinal fluid (CSF) examination perhaps needs increased emphasis,” Dr. Cohen said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “It’s been somewhat de-emphasized in previous versions of the criteria. Then, there was identification of subsets of patients that were felt to have a high likelihood of MS but in whom the diagnosis could not be made by the current criteria – patients who fell through the cracks. There was also increasing recognition of the frequency and important consequences of misdiagnosis.”

NEW ORLEANS – Safety and efficacy laboratory monitoring of adherence to disease-modifying therapies for multiple sclerosis remains challenging, results from a small pilot study showed.

In an effort to determine if select patients on specific DMTs are receiving appropriate and adequate monitoring as outlined by each DMT’s internal guidance document, Felecia Hart, PharmD, and her associates retrospectively reviewed existing patients treated for MS at the Rocky Mountain Multiple Sclerosis Center at the University of Colorado, Denver, between June 1, 2013, and June 1, 2016.

NEW ORLEANS – Risk tolerance to current disease modifying therapies by patients with multiple sclerosis varies widely, results from a large national survey demonstrated.

“We have therapies available with a wide range of risks,” study author Sneha Natarajan, PhD, said in an interview at the annual meeting of the Consortium of Multiple Sclerosis Centers. “Some of the risks are relatively minor like injection site reactions or flu-like symptoms and some are as bad as PML [progressive multifocal leukoencephalopathy], which can be fatal. We don’t know what kind of risks people tolerate.”

Minocycline, an antibiotic that has immune-modulating properties and crosses the blood-brain barrier, appears to delay conversion to multiple sclerosis in patients who have an initial focal demyelinating event, according to a report published online June 1 in the New England Journal of Medicine.

Two small clinical trials involving patients with relapsing-remitting multiple sclerosis (MS) recently showed that minocycline reduces the number of lesions detected on MRI with gadolinium enhancement. So researchers led by Luanne M. Metz, MD, of the Cumming School of Medicine and the Hotchkiss Brain Institute, Calgary, Alta., conducted a randomized, double-blind, placebo-controlled trial at 12 Canadian MS clinics to determine whether the drug might delay conversion to MS after a first, clinically isolated demyelinating event, such as optic neuritis or a brainstem, cerebral, cerebellar, or myelopathy syndrome.
