Phase 3 data support apixaban for cancer-associated VTE
SAN DIEGO – according to the Phase 3 ADAM VTE trial.
The rates of major bleeding and clinically relevant nonmajor bleeding in patients who received apixaban were similar to those in patients who received dalteparin. However, the rate of VTE recurrence was significantly lower with apixaban than it was with dalteparin.
“[A]pixaban was associated with very low bleeding rates and venous thrombosis recurrence rates compared to dalteparin,” said Robert D. McBane II, MD, of the Mayo Clinic in Rochester, Minn., at the annual meeting of the American Society of Hematology.
The trial included 300 adults (aged 18 years and older) with active cancer and acute VTE who were randomized to receive apixaban (n = 150) or dalteparin (n = 150). The dose and schedule for oral apixaban was 10 mg twice daily for 7 days followed by 5 mg twice daily for 6 months. Dalteparin was given subcutaneously at 200 IU/kg per day for 1 month followed by 150 IU/kg daily for 6 months. Among the patients in the study, 145 patients in the apixaban arm and 142 in the dalteparin arm ultimately received their assigned treatment.
Every month, patients completed an anticoagulation satisfaction survey and bruise survey (a modification of the Duke Anticoagulation Satisfaction Scale). They also underwent lab testing (complete blood count, liver and renal function testing) and were assessed for outcomes, medication reconciliation, drug compliance, and ECOG status on a monthly basis.
Patient characteristics
Baseline characteristics were similar between the treatment arms. The mean age was 64 years in both arms, and roughly half of patients in both arms were female. Hematologic malignancies were present in 9% of patients in the apixaban arm and 11% in the dalteparin arm. Others included lung, colorectal,
pancreatic/hepatobiliary, gynecologic, breast, genitourinary, upper gastrointestinal, and brain cancers.
Of patients in the study, 65% of those in the apixaban arm and 66% in the dalteparin arm had distant metastasis, and 74% of patients in both arms were receiving chemotherapy while on study.
Patients had the following qualifying thrombotic events:
- Any pulmonary embolism (PE) – 55% of patients in the apixaban arm and 51% in the dalteparin arm
- Any deep vein thrombosis (DVT) – 48% and 47%, respectively
- PE only – 44% and 39%, respectively
- PE with DVT – 12% in both arms
- DVT only – 37% and 35%, respectively
- Lower extremity DVT – 31% and 34%, respectively
- Upper extremity DVT – 17% and 14%, respectively
- Cerebral venous thrombosis (VT) – 1% and 0%, respectively
- Splanchnic VT – 8% and 18%, respectively.
Bleeding, thrombosis, and death
The study’s primary endpoint was major bleeding, which did not occur in any of the apixaban-treated patients. However, major bleeding did occur in two (1.4%) patients in the dalteparin arm (P = .14).
A secondary endpoint was major bleeding plus clinically relevant nonmajor bleeding. This occurred in nine (6.2%) patients in the apixaban arm and nine (6.3%) in the dalteparin arm (P = .88).
The researchers also assessed VTE recurrence. One patient in the apixaban arm (0.7%) and nine in the dalteparin arm (6.3%) had VTE recurrence (P = .03).
The patient in the apixaban arm experienced cerebral VT, and the patients with recurrence in the dalteparin arm had leg (n = 4) or arm (n = 2) VTE, PE (n = 1), or splanchnic VT (n = 2).
One patient in each arm (0.7%) had arterial thrombosis.
There was no significant difference in cumulative mortality between the treatment arms (hazard ratio, 1.40; P = .3078).
Satisfaction and discontinuation
Overall, apixaban fared better than dalteparin in the monthly patient satisfaction surveys. At various time points, apixaban-treated patients were significantly less likely to be concerned about excessive bruising, find anticoagulant treatment a burden or difficult to carry out, or say anticoagulant treatment added stress to their lives, negatively impacted their quality of life, or caused them “a great deal” of worry, irritation, or frustration.
However, apixaban-treated patients were less likely than dalteparin recipients to have confidence that their drug protected them from VTE recurrence, while the apixaban recipients were more likely than the dalteparin group to report overall satisfaction with their treatment.
In addition, premature treatment discontinuation was more common in the dalteparin group than in the apixaban group – 15% and 4%, respectively (P = .0012).
“Apixaban was well tolerated with superior patient safety satisfaction, as well as significantly fewer study drug discontinuations compared to dalteparin,” Dr. McBane said. “I believe that these data support the use of apixaban for the acute treatment of cancer-associated venous thromboembolism.”
This study was funded by BMS/Pfizer Alliance. Dr. McBane declared no other conflicts of interest.

Open enrollment 2019: Busiest week so far at HealthCare.gov
but the weekly and cumulative totals for plans selected continued to run below last year’s levels, according to the Centers for Medicare & Medicaid Services.
Over 934,000 plans were selected from Dec. 2 to Dec. 8, which puts the total at 4.13 million plans for the 2019 coverage year in the 39 states that use the HealthCare.gov platform, the CMS reported. Consumers renewing their coverage make up the majority of plans selected during week 6 (640,000) and cumulatively for the season (3.03 million), with new applications running at 295,000 for week 6 and 1.1 million overall.
Those numbers are down from last year, when 1.07 million plans (685,000 renewals and 389,000 new applications) were selected during week 6 of open enrollment for the 2018 coverage year, which brought the total for the season at the time to 4.68 million (3.30 million/1.38 million), CMS data show.

FDA issues alert over e-liquids with undeclared drugs
The Food and Drug Administration has issued an alert regarding two . E-liquid is the flavored mixture used in electronic cigarettes.
In a laboratory analysis, the FDA found that “E-Cialis HelloCig E-Liquid” contained both sildenafil and tadalafil, and that “E-Rimonabant HelloCig E-Liquid” contained sildenafil. Sildenafil and tadalafil are approved for the treatment of erectile dysfunction. Unapproved usage of these drugs in over-the-counter e-liquids is therefore illegal.
Both sildenafil and tadalafil can interact with nitrates found in some prescription drugs and can cause a dangerous lowering of blood pressure. Conditions commonly treated with nitrates include diabetes, high blood pressure, high cholesterol, or heart disease.
“FDA recently warned HelloCig of these issues and contacted the company several times to recommend they recall these products due to the risks to consumers. However, HelloCig has not responded to the agency’s recommendation. Therefore, FDA urges consumers to stop using these products and to contact their health care professional with any concerns associated with their use,” the FDA said in the press release.

Severe adverse events seen in placebo arm of cancer clinical trials
A significant number of patients who receive only a placebo in a clinical trial of cancer immunotherapy still experience grade three or grade four adverse events, research suggests.
Writing in JAMA Network Open, researchers reported the outcomes of a systematic review and meta-analysis of 10 randomized, double-blind, placebo-controlled, phase 3 trials of targeted therapy or immunotherapy drugs for cancer, in which patients in the placebo group were treated only with placebo and no other anticancer drugs.
Among the 4,873 patients who were randomized to placebo, a mean of 85.1% experienced some sort of placebo adverse event. The overall incidence of grade 3-4 placebo adverse events was 18% but was as high as 25% in two trials – one in renal cell carcinoma and one in melanoma – and as low as 11% in one trial.
Hypertension was the most frequent grade 3-4 adverse event among patients on placebo, experienced by a mean of 2.8% of patients, followed by fatigue (1%) and diarrhea (0.8%).
Neither route of administration nor cancer type made a significant difference in terms of the rate of placebo adverse events. No deaths attributed to the placebo were reported, but the mean rate of discontinuation due to placebo adverse events was 3.9%, and was higher than 5% for four trials.
The median duration of placebo administration ranged from 10 to 15 months for all but one study, and the authors noted that the longer the placebo exposure, the higher the proportion of grade 3-4 adverse events.
The investigators – Matías Rodrigo Chacón, MD, and his colleagues in the research department at the Argentine Association of Clinical Oncology – said that studies with a lower incidence of grade 3-4 adverse events in the treatment arm also had a lower incidence of grade 3-4 placebo adverse events, while the higher incidences of placebo adverse events were seen in studies that also had a higher incidence of treatment-related adverse events.
They suggested that “contextual factors,” such as the information given during the informed consent process, could contribute to negative expectations of adverse events.
“To illustrate this point, in an RCT [randomized controlled trial] of aspirin as a treatment for unstable angina, a higher incidence of gastrointestinal irritation was reported in centers that specified its potential occurrence in the informed consent compared with research units that did not include that risk,” they wrote.
They also suggested that patients may experience anxiety associated with the uncertainty about whether they had received active treatment or placebo, and this could also affect their distress levels.
No conflicts of interest were declared.

Wasp-stung lung bugs, fat clay, Botoxed Vulcans, and ‘GOT’ mortality risk
The wonderful world of wasps
Never thought you’d be thankful for wasps, did you? Neither did we. Using mice as test subjects, scientists at MIT found that a tiny peptide in the venom was able to completely eliminate Pseudomonas aeruginosa, which causes respiratory infections and is often resistant to antibiotics. Now if you’re sick, all you have to do is go outside and get stung by a bunch of wasps!
Wait, no, that’s not right. The researchers at MIT engineered a molecule that can be used to create an antibiotic that’s safe for humans. While most insect venom is chock full of compounds that are toxic to humans, the scientists were able to transform their tiny peptide into a bacteria-defeating machine. This is a big victory in the war against antibiotic-resistant bacteria. Go, wasps!
Live long and Botox
Talk about highly illogical! Botox patients sometimes return for follow-up visits with dermatologist Kelly Stankiewicz, MD, and haven’t noticed they’ve “Spocked,” even though it may be obvious to just about everyone else.
But other Botox patients are most certainly aware that their eyebrows have arched up on the right and left sides – just like those of a certain Vulcan character on “Star Trek.” And they want to be beamed out of that uncomfortable situation pronto.
Dr. Stankiewicz, who works in Park City, Utah, explained the “Spocking” phenomenon in a presentation about facial treatments at the recent Las Vegas Dermatology Symposium. Spocking can occur in patents who get Botox treatment to eliminate the “11 line” – two vertical wrinkles – between the eyebrows, Dr. Stankiewicz said. It occurs “when the middle of the forehead doesn’t move but the outside does,” she said, causing an unsightly outwardly arched eyebrow look.
The solution to Spocking is easy, she said: “Put a tiny bit of Botox in the forehead muscle right where the eyebrow is peaking the most.”
Leonard Nimoy, the original Mr. Spock, is not available for comment, given that he died in 2015. But Dr. Stankiewicz does have a perspective on Mr. Spock’s trademark look: “It’s like the people who drew his brow knew that Botox was on the horizon.”
Add the dirt, lose the fat
Lots of things are supposed to be stronger than dirt, but it looks like obesity might not be one of them. Investigators who were trying to improve drug delivery using a type of clay – spray-dried smectite clay particles, to be exact – discovered that it has “a unique ability to ‘soak up’ fat droplets in the gut,” according to a statement from the University of South Australia, Adelaide.
“Not only were the clay materials trapping the fats within their particle structure, but they were also preventing them from being absorbed by the body, ensuring that fat simply passed through the digestive system,” researcher Tahnee J. Dening said.
In the study, the smectite outperformed the weight-loss drug orlistat in rats fed a high-fat diet for 2 weeks (Pharm Res. 2019;36:21 doi: 10.1007/s11095-018-2552-9). Even better, smectite is already widely used in foods and nutraceuticals and is considered to be safe. Even even better, smectite is a really fun word to say. And with the prevalence of obesity such as it is, we’re sure that physicians will prescribe smectite just so they can say “smectite” to their patients. Smectite.
When you play the game of thrones …
… You conduct an evidence-based analysis of mortality across the Seven Kingdoms. In celebration of the approaching final season, two researchers published a study of mortality and survival in HBO’s “Game of Thrones” series. They examined data on sociodemographic factors and circumstances of death to identify predictors of mortality.
After looking at 330 characters from the show (186 who suffered death), the authors determined that being male, lowborn, and loyal had the highest correlation with mortality. Poor men who never switched their allegiance from one side to the other had the lowest chance of survival. In addition, the probability of dying in the first hour after appearing on screen was 14%. Not a good statistic if you’re trying to become famous in Westeros. And a mortality risk rivaling even that of Mr. Spock’s red-shirted shipmates down in engineering.
Nurse, sand wedge, STAT!
There really is no sport like golf. The wide green spaces, the fresh air, the thrill of launching a 300-yard drive down the fairway, the fun of double-bogeying the last three holes to shoot yet another 93; golf is a noble pursuit, indeed. And a sport everyone knows doctors love. Right?
In research published in the Christmas edition of the BMJ, a group of doctors from Massachusetts sought to find out just how accurate the stereotype was. Their answer? Doctors really do enjoy teeing it up.
Well, male doctors.
Well, old male doctors.
Using a database of about a million physicians, the researchers found that 5.5% of male physicians and 1.3% of female physicians – or 4.1% overall – maintained an official United States Golf Association handicap. Male physicians aged 61-70 years were most likely to play, and female physicians aged 31-35 years were least likely.
However, while golf is certainly a common pastime among doctors, they aren’t exactly very good at it, as the average doctor is actually slightly worse than the average nondoctor. Surgeons presented a notable exception, possessing significantly lower handicaps than their colleagues while, perhaps not coincidentally, also playing more often. We’re sure there’s a joke about overpaid surgeons in narrow specialties having too much time on their hands, and we’ll get right back to you with it after our 12 o’clock tee time.
The wonderful world of wasps
Never thought you’d be thankful for wasps, did you? Neither did we. Using mice as test subjects, scientists at MIT found that a tiny peptide in the venom was able to completely eliminate Pseudomonas aeruginosa, which causes respiratory infections and is often resistant to antibiotics. Now if you’re sick, all you have to do is go outside and get stung by a bunch of wasps!
Wait, no, that’s not right. The researchers at MIT engineered a molecule that can be used to create an antibiotic that’s safe for humans. While most insect venom is chock full of compounds that are toxic to humans, the scientists were able to transform their tiny peptide into a bacteria-defeating machine. This is a big victory in the war against antibiotic-resistant bacteria. Go, wasps!
Live long and Botox
Talk about highly illogical! Botox patients sometimes return for follow-up visits with dermatologist Kelly Stankiewicz, MD, and haven’t noticed they’ve “Spocked,” even though it may be obvious to just about everyone else.
But other Botox patients are most certainly aware that their eyebrows have arched up on the right and left sides – just like those of a certain Vulcan character on “Star Trek.” And they want to be beamed out of that uncomfortable situation pronto.
Dr. Stankiewicz, who works in Park City, Utah, explained the “Spocking” phenomenon in a presentation about facial treatments at the recent Las Vegas Dermatology Symposium. Spocking can occur in patents who get Botox treatment to eliminate the “11 line” – two vertical wrinkles – between the eyebrows, Dr. Stankiewicz said. It occurs “when the middle of the forehead doesn’t move but the outside does,” she said, causing an unsightly outwardly arched eyebrow look.
The solution to Spocking is easy, she said: “Put a tiny bit of Botox in the forehead muscle right where the eyebrow is peaking the most.”
Leonard Nimoy, the original Mr. Spock, is not available for comment, given that he died in 2015. But Dr. Stankiewicz does have a perspective on Mr. Spock’s trademark look: “It’s like the people who drew his brow knew that Botox was on the horizon.”

‘Optimal’ pazopanib levels linked to lower toxicity in RCC patients
In patients with renal cell carcinoma, trough concentrations of pazopanib in a specific target range were associated with better safety and comparable efficacy, versus higher concentrations of the drug, authors of an exploratory investigation have reported.
Fewer serious toxicities were seen in patients with pazopanib concentrations in the 20- to 50-mcg/mL range, yet overall response rate was similar compared to patients with concentrations over 50 mcg/mL, according to results of the retrospective study.
The findings suggest therapeutic drug monitoring to achieve a specific trough concentration may be useful to optimize pazopanib dosing, according to investigator Tomohiro Terada, PhD, of Shiga University of Medical Science Hospital, Japan, and coinvestigators.
Therapeutic drug monitoring for sunitinib in RCC patients was recently covered by medical insurance in Japan, Dr. Terada and colleagues wrote in Clinical Genitourinary Cancer.
The strategy may be especially suited to adjusting the dose of pazopanib, which is often associated with severe toxicities and has pharmacokinetics that suggest a wide variation between individuals, they added.
The retrospective study by Dr. Terada and colleagues included 27 renal cell carcinoma patients who received pazopanib at doses of 400, 600, or 800 mg daily based on the recommendation of the treating physician, with doses reduced or discontinued based on adverse events or progression.
Trough concentrations of pazopanib 3 months after starting the treatment ranged from a low of 10.6 mcg/mL to a high of 106 mcg/mL, with a median of 49.1 mcg/mL, according to the report.
One-third of patients experienced grade 3 or greater toxicities, including anorexia, hypertension, anemia, and thrombocytopenia, among others. The median pazopanib concentration for those nine patients was 69.3 mcg/mL, compared with 41.2 mcg/mL for those not experiencing serious toxicities (P less than .05).
A concentration over 50.3 mcg/mL predicted grade 3 or greater toxicity, statistical analysis showed, with 8 out of 13 patients with concentrations above that threshold experiencing serious toxicities. By contrast, 1 of 14 patients below that threshold experienced grade 3 or greater toxicities.
No responses were observed in three patients with pazopanib concentrations below 20.5 mcg/mL, a concentration level considered to be subtherapeutic based on previous investigations.
Overall response rates were similar for patients with concentrations in the “optimal” 20.5- and 50.3-mcg/mL range and those with concentrations over 50.3 mcg/mL, according to the investigators.
Among 11 patients in that “optimal” range, partial responses were seen in 5, they reported, while for the 13 patients with high concentrations of the drug, partial responses were seen in 4 patients and a complete response was seen in 1 patient.
Trough concentrations may not predict all types of toxicities, according to the investigators, who said that the results of their small, retrospective analysis should be validated in a large, prospective study.
In particular, there was no significant relationship between trough concentration of pazopanib and development of grade 2 or greater hepatotoxicity, a common and specific side effect of the drug.
“Based on these findings, pazopanib-induced hepatotoxicity may not be related to the pharmacokinetics of pazopanib,” they wrote. “Therefore, pharmacogenomics testing is needed to predict pazopanib-induced hepatotoxicity.”
Dr. Terada and coauthors said they had no conflicts of interest to report.

Bioequivalents lamotrigine, levetiracetam control new-onset focal seizures equally well
NEW ORLEANS – Bioequivalent generic formulations of levetiracetam and lamotrigine reduced seizures by a similar extent over 2 years in a retrospective study of patients with newly diagnosed focal epilepsy.
Each drug had a specific adverse event profile, with lamotrigine associated with rash and levetiracetam with mood disorders, Sirichai Chayasirisobhon, MD, said at the annual meeting of the American Epilepsy Society. This finding can play into the initial therapeutic decision, said Dr. Chayasirisobhon of Kaiser Permanente Southern California. “If someone comes in with depression or mood disorder, I will start on lamotrigine, not levetiracetam. And we can decrease the chance of rash with a very slow titration, as we did here, starting with just 5 mg/kg and working up over 6 months.”
Although the drugs have a somewhat similar teratogenic profile, Dr. Chayasirisobhon added that he favors lamotrigine for women of childbearing years. “It’s a little bit better choice for them I think.”
His retrospective analysis followed 442 patients from first seizure and medical therapy for 2 years. The generic medications came from Kaiser Permanente’s central pharmacy. They were single-source, with a proven 95% bioequivalence. The main outcome was the percentage of patients who became seizure free and remained so. Any seizure, whether febrile, breakthroughs, or from titration, was considered a failure. These patients were dropped from the study. Any patient who developed a drug-related rash was dropped from the study and started on another medication.
More women than men took lamotrigine (113 vs. 75), whereas more men took levetiracetam (148 vs. 106). Those taking lamotrigine were younger than were those taking levetiracetam (30 vs. 40 years).
At the end of 2 years, there was no statistically significant difference in the primary outcome of being free from seizures (66.5% with lamotrigine vs. 72.4% with levetiracetam). In the lamotrigine group, 33.5% were eliminated from the study, 24% because they had a seizure, and the rest due to an adverse event. In the levetiracetam group, 27.6% were eliminated, 13% because they had a seizure and the rest because of an adverse event.
Adverse events in the lamotrigine group included rash (12), dizziness (3), lethargy (1), and mood changes (2). Among the levetiracetam group, adverse events included dizziness (3), lethargy (7), mood changes (20), slowed thinking (4), depression (2) and headache (1).
“Rash was the main event we saw in this group, and this was even when we did a very slow titration of 5 mg/kg per week,” Dr. Chayasirisobhon said. “Any sign of rash or itching at all, we told them to stop immediately and call us. Fortunately, we had no cases of Steven-Johnson syndrome and all our cases of rash were transient. But in the levetiracetam group, the mood changes are the major thing. Some of the patients became very agitated and aggressive. Whenever we see a patient for the first time, we always ask about mood changes, and we instruct the family to call and report any changes in mood immediately.”
Aside from reproductive age, however, Dr. Chayasirisobhon generally prefers to start new patients on levetiracetam. Its safety profile is remarkable, he said, recounting a case report he published in 2010 (Acta Neurol Taiwan. 2010;19:292-5).
The paper describes a male patient who decided to commit suicide after an argument with his wife. He took his levetiracetam and walked to his father’s grave, swallowing pills the entire time. When he arrived at the grave, he had taken around 65 grams of the medication. “The amazing thing was, he’s still walking, just a little unsteady. Then he decided he’s not ready to die,” Dr. Chayasirisobhon said. “He was able to call 911, so he’s still talking fine. When they checked his level it was so high, but he remained unimpaired except for the unsteady gait and some nystagmus.”
The study did not receive outside funding. Dr. Chayasirisobhon had no financial disclosures.

When he arrived at the grave, he had taken around 65 grams of the medication. “The amazing thing was, he’s still walking, just a little unsteady. Then he decided he’s not ready to die,” Dr. Chayasirisobhon said. “He was able to call 911, so he’s still talking fine. When they checked his level it was so high, but he remained unimpaired except for the unsteady gait and some nystagmus.”
The study did not receive outside funding. Dr. Chayasirisobhon had no financial disclosures.
NEW ORLEANS – Bioequivalent generic formulations of levetiracetam and lamotrigine reduced seizures by a similar extent over 2 years in a retrospective study of patients with newly diagnosed focal epilepsy.
Each drug had a specific adverse event profile, with lamotrigine associated with rash and levetiracetam with mood disorders, Sirichai Chayasirisobhon, MD, said at the annual meeting of the American Epilepsy Society. This finding can play into the initial therapeutic decision, said Dr. Chayasirisobhon of Kaiser Permanente Southern California. “If someone comes in with depression or mood disorder, I will start on lamotrigine, not levetiracetam. And we can decrease the chance of rash with a very slow titration, as we did here, starting with just 5 mg/kg and working up over 6 months.”
Although the drugs have a somewhat similar teratogenic profile, Dr. Chayasirisobhon added that he favors lamotrigine for women of childbearing years. “It’s a little bit better choice for them I think.”
His retrospective analysis followed 442 patients from first seizure and medical therapy for 2 years. The generic medications came from Kaiser Permanente’s central pharmacy. They were single-source, with a proven 95% bioequivalence. The main outcome was the percentage of patients who became seizure free and remained so. Any seizure, whether febrile, breakthroughs, or from titration, was considered a failure. These patients were dropped from the study. Any patient who developed a drug-related rash was dropped from the study and started on another medication.
More women than men took lamotrigine (113 vs. 75), whereas more men took levetiracetam (148 vs. 106). Those taking lamotrigine were younger than were those taking levetiracetam (30 vs. 40 years).
At the end of 2 years, there was no statistically significant difference in the primary outcome of being free from seizures (66.5% with lamotrigine vs. 72.4% with levetiracetam). In the lamotrigine group, 33.5% were eliminated from the study, 24% because they had a seizure, and the rest due to an adverse event. In the levetiracetam group, 27.6% were eliminated, 13% because they had a seizure and the rest because of an adverse event.
Adverse events in the lamotrigine group included rash (12), dizziness (3), lethargy (1), and mood changes (2). Among the levetiracetam group, adverse events included dizziness (3), lethargy (7), mood changes (20), slowed thinking (4), depression (2) and headache (1).
“Rash was the main event we saw in this group, and this was even when we did a very slow titration of 5 mg/kg per week,” Dr. Chayasirisobhon said. “Any sign of rash or itching at all, we told them to stop immediately and call us. Fortunately, we had no cases of Steven-Johnson syndrome and all our cases of rash were transient. But in the levetiracetam group, the mood changes are the major thing. Some of the patients became very agitated and aggressive. Whenever we see a patient for the first time, we always ask about mood changes, and we instruct the family to call and report any changes in mood immediately.”
Aside from reproductive age, however, Dr. Chayasirisobhon generally prefers to start new patients on levetiracetam. Its safety profile is remarkable, he said, recounting a case report he published in 2010 (Acta Neurol Taiwan. 2010;19:292-5).

Rural teleprescribing for opioid use disorder shows success
BONITA SPRINGS, FLA. – Clinician shortages and alarming opioid overdose rates are prompting rural health care centers to turn to telemedicine for delivering treatments for opioid use disorder (OUD). Several studies suggest that these treatments are being delivered effectively, experts said at the annual meeting of the American Academy of Addiction Psychiatry.
In both Maryland and West Virginia, for example, success using a telehealth approach has been reported recently, said David Moore, MD, PhD, assistant professor of psychiatry at Yale University, New Haven, Conn.
Specifically, in rural Maryland, physicians used telemedicine to provide buprenorphine treatment for OUD at a treatment center in August 2015. Researchers at the University of Maryland, Baltimore, looked at the first 177 of the patients treated with the approach. They found that retention in treatment was 91% at 1 month and 57% at 3 months. Of patients still in treatment at 3 months, 86% had urine that was opioid negative, researchers said (Am J Addict. 2018 Dec;27[8]:612-17).
And in West Virginia, researchers reviewed the records of 100 patients receiving buprenorphine treatment to compare outcomes of those treated with telemedicine and those treated face-to-face. They found no significant differences between the groups in additional substance use, time to achieve 30 days and 90 days of abstinence, or retention rates at 3 months and 1 year (J Addict Med. 2017 Mar-Apr;11[2]:138-44).
In addition, Dr. Moore said, he has had success with home inductions in the northern reaches of Maine. His first home induction involved a 55-year-old veteran with a history of oxycodone and hydrocodone use who used illicit buprenorphine when he could. Dr. Moore said the man was referred to him on a Monday. He called in a prescription for the drug the next day and gave the patient a handout on how to do a home induction. “Then he had a phone check-in, and we followed up on Thursday. It actually worked really well,” Dr. Moore said.
The dearth of buprenorphine providers in northern Maine makes those kinds of arrangements attractive, he said. In Maine’s Piscataquis County, he said, there is one buprenorphine provider for every 2,000 square miles. “We have about 1 in every 5 square miles in New Haven,” he said. “Thinking about the distance you have to travel, it gets to be pretty daunting.”
The ability of clinicians to provide buprenorphine with telemedicine varies by state. Among the resources needed to provide telemedicine services are reliable Internet access and an ability for a patient to consent to the treatment.
Nationwide, 56.3% of rural counties have no buprenorphine provider, according to a recent study, said Lewei (Allison) Lin, MD, assistant professor of psychiatry at the University of Michigan, Ann Arbor. A survey of 1,100 rural providers, results of which were included in that study, found that 48% of them said concerns about substance diversion or misuse were a barrier to providing buprenorphine, and 44% cited a lack of mental health or psychosocial support services.
“Although this country still has a major issue with access to treatment, we see that the access problem is about double in rural areas,” she said. “If you add on the distance issue and time, this becomes an even greater challenge.”
Nurse practitioners and physician assistants are now able to obtain a Drug Enforcement Administration waiver that will allow them to prescribe OUD, thanks to the Comprehensive Addiction and Recovery Act of 2016.

Brazil sees first live birth from deceased-donor uterus transplant
The healthy 2,550-g infant girl was born in December 2017 via a planned cesarean delivery at about 36 weeks’ gestation. Her mother, the transplant recipient, has congenital absence of the uterus from Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Removal of the transplanted uterus at the time of delivery allowed the woman to stop taking the immunosuppressive medications that she’d been on since the transplantation, which had been performed less than a year and a half previously.
The uterus had been retrieved from a 45-year-old donor who experienced a subarachnoid hemorrhage and subsequent brain death. The donor had three vaginal deliveries, and no history of reproductive issues or sexually transmitted infection, wrote Dani Ejzenberg, MD, and his colleagues at the University of São Paolo, Brazil.
The retrieval and transplantation procedures were done at the university’s hospital, in accordance with a research protocol approved by the university, a Brazilian national ethics committee, and the country’s national transplantation system. Thorough psychological evaluation was part of the research protocol, and the patient and her partner had monthly psychological counseling from therapists with expertise in transplant and fertility, wrote Dr. Ejzenberg and his colleagues.
In preparation for the transplantation, which occurred when the recipient was 32 years old, she had in vitro fertilization several months before the procedure. Eight “good-quality” blastocysts were retrieved and cryopreserved, said Dr. Ejzenberg and his coauthors. The recipient’s menstrual cycle resumed 37 days after transplantation, and one of the cryopreserved embryos was transferred about 7 months after the uterine transplantation procedure, resulting in the pregnancy.
The donor and recipient were matched only by ABO blood type, with no further tissue typing being done, wrote Dr. Ejzenberg and his colleagues. The immunosuppressive regimen paralleled that used in previous successful uterine transplantations from live donors in Sweden, with induction via 1 g intraoperative methylprednisolone and 1.5 mg/kg of thymoglobulin. Thereafter, the recipient received tacrolimus titrated to a trough of 8-10 ng/mL, along with mycophenolate mofetil 720 mg twice daily. Five months after her transplantation, the mycophenolate mofetil was replaced with 100 mg azathioprine and 10 mg prednisone daily, a regimen that she stayed on until cesarean delivery.
Broad-spectrum antibiotics, antifungals, and anthelmintics were administered during the patient’s hospital stay. Prophylactic antibiotics were continued for 6 months, and antiviral medication was given prophylactically for 3 months. The recipient had one episode of vaginal discharge, treated with antifungal medication, and one episode of pyelonephritis during pregnancy, treated during a brief inpatient stay.
Enoxaparin and aspirin were used for inpatient venous thromboembolism prophylaxis, and heparin and aspirin thereafter. Aspirin was discontinued at 34 weeks, and heparin the day before delivery.
Swedish and American teams involved in uterine transplantation are working to develop standardization of surgical techniques, immunosuppression protocol, and methods to monitor rejection.
However, pointed out Dr. Ejzenberg and his coauthors, some technical aspects were unique to the deceased donor transplantation. These included managing total ischemic time for the donor tissue because heart, liver, and kidney retrieval all were given priority.
One downstream effect of this was longer-than-expected procedure and anesthesia time for the recipient, because coordinating donor uterus retrieval and preparation of the surgical bed in the live recipient was tricky; surgery time was about 10.5 hours. Also, there was prolonged warm-ischemia time because six small-vessel anastomoses needed to be performed, wrote the investigators.
After reperfusion of the implanted uterus, there was brisk bleeding from a number of small vessels that had not been ligated on retrieval because of concerns about ischemic time. These were identified and sutured or cauterized, but the total estimated blood loss during the procedures was 1,200 mL, with most of that coming from the uterus, said Dr. Ejzenberg and his coauthors.
The donor uterus had a total of almost 8 hours of ischemic time, exceeding the previously published live donor maximum uterine ischemic time of 3 hours, 25 minutes. This experience can inform surgical teams considering future uterine transplantations.
Dr. Ejzenberg and his colleagues also said that they cast a broad net with immunosuppression, erring on the side of caution. With more experience may come the ability to scale back immunosuppressive regimens, they noted.
The explantation of the uterus and associated blood vessels after delivery afforded the opportunity for pathological examination of the uterus and other tissues, which showed no signs of rejection. The uterine arteries did have mild intimal fibrous hyperplasia that was likely related to the age of the donor, said Dr. Ejzenberg and his coauthors.
This successful completion of a deceased-donor uterine transplantation demonstrates the feasibility of accessing “a much wider potential donor population, as the numbers of people willing and committed to donate organs upon their own deaths are far larger than those of potential live donors,” wrote Dr. Ejzenberg and his colleagues. “Further incidental but substantial benefits of the use of deceased donors include lower costs and avoidance of live donors’ surgical risks.”
In 2011, a uterine transplantation from a deceased donor resulted in pregnancy, but ended in miscarriage.
Funding was provided by Fundação de Amparo à Pesquisa do Estado de São Paulo and the Hospital das Clínicas of University of São Paulo School of Medicine. Dr. Ejzenberg and his colleagues reported that they had no conflicts of interest.

Among the advances seen in this deceased-donor uterus transplant is a demonstration that ischemic time of nearly 8 hours – four times the average seen in live donation – does not preclude a successful transplantation. 
Also, the timetable for transplantation seen here did not involve the year-long waiting period between transplantation and pregnancy that has been the norm in live uterine transplantation.
However, uterine transplantation, whether from a living or deceased donor, is still in its early stages. Among the many unsettled questions are whether live or deceased donor transplantations yield superior results. Additional technical aspects to be further studied include best surgical approach for the donor uterus, best anastomosis technique, and optimal immunosuppression and antimicrobial/antifungal/antiviral regimens.
Continued work needs to be done to standardize these and other aspects of the peri- and postoperative care of women undergoing uterine transplantation.
In addition, long-term tracking of children born from transplanted uteri is needed, so outcomes can be assessed over the lifespan.
Going forward, it could be that uterine transplantation may be offered to an expanded cohort of women, including those with bulky, nonoperable uterine fibroids, those who have received pelvic radiotherapy, and even those who have had multiple unexplained problems with implantation during fertility treatments. In all cases, researchers should work toward achieving the highest live birth rate at the lowest risk to donors and patients, while also working to make more organs available; establishing registries, and encouraging prospective registration and transparent reporting of uterus transplantation procedures.

Thereafter, the recipient received tacrolimus titrated to a trough of 8-10 ng/mL, along with mycophenolate mofetil 720 mg twice daily. Five months after her transplantation, the mycophenolate mofetil was replaced with 100 mg azathioprine and 10 mg prednisone daily, a regimen that she stayed on until cesarean delivery.
Broad-spectrum antibiotics, antifungals, and anthelmintics were administered during the patient’s hospital stay. Prophylactic antibiotics were continued for 6 months, and antiviral medication was given prophylactically for 3 months. The recipient had one episode of vaginal discharge, treated with antifungal medication, and one episode of pyelonephritis during pregnancy, treated during a brief inpatient stay.
Enoxaparin and aspirin were used for inpatient venous thromboembolism prophylaxis, and heparin and aspirin thereafter. Aspirin was discontinued at 34 weeks, and heparin the day before delivery.
Swedish and American teams involved in uterine transplantation are working to develop standardization of surgical techniques, immunosuppression protocol, and methods to monitor rejection.
However, pointed out Dr. Ejzenberg and his coauthors, some technical aspects were unique to the deceased donor transplantation. These included managing total ischemic time for the donor tissue because heart, liver, and kidney retrieval all were given priority.
One downstream effect of this was longer-than-expected procedure and anesthesia time for the recipient, because coordinating donor uterus retrieval and preparation of the surgical bed in the live recipient was tricky; surgery time was about 10.5 hours. Also, there was prolonged warm-ischemia time because six small-vessel anastomoses needed to be performed, wrote the investigators.
After reperfusion of the implanted uterus, there was brisk bleeding from a number of small vessels that had not been ligated on retrieval because of concerns about ischemic time. These were identified and sutured or cauterized, but the total estimated blood loss during the procedures was 1,200 mL, with most of that coming from the uterus, said Dr. Ejzenberg and his coauthors.
The donor uterus had a total of almost 8 hours of ischemic time, exceeding the previously published live donor maximum uterine ischemic time of 3 hours, 25 minutes. This experience can inform surgical teams considering future uterine transplantations.
Dr. Ejzenberg and his colleagues also said that they cast a broad net with immunosuppression, erring on the side of caution. With more experience may come the ability to scale back immunosuppressive regimens, they noted.
The explantation of the uterus and associated blood vessels after delivery afforded the opportunity for pathological examination of the uterus and other tissues, which showed no signs of rejection. The uterine arteries did have mild intimal fibrous hyperplasia that was likely related to the age of the donor, said Dr. Ejzenberg and his coauthors.
This successful completion of a deceased-donor uterine transplantation demonstrates the feasibility of accessing “a much wider potential donor population, as the numbers of people willing and committed to donate organs upon their own deaths are far larger than those of potential live donors,” wrote Dr. Ejzenberg and his colleagues. “Further incidental but substantial benefits of the use of deceased donors include lower costs and avoidance of live donors’ surgical risks.”
In 2011, a uterine transplantation from a deceased donor resulted in pregnancy, but ended in miscarriage.
Funding was provided by Fundação de Amparo à Pesquisa do Estado de São Paulo and the Hospital das Clínicas of University of São Paulo School of Medicine. Dr. Ejzenberg and his colleagues reported that they had no conflicts of interest.

Real-world data reveal long-lasting effects achieved with RRMS treatments
BERLIN – Real-world data from six postmarketing surveillance studies suggest that currently available disease-modifying treatments (DMTs) for relapsing-remitting multiple sclerosis (RRMS) have long-lasting effects that are matched by reasonable tolerability.
Long-term efficacy and safety data on natalizumab (Tysabri), fingolimod (Gilenya), alemtuzumab (Lemtrada), dimethyl fumarate (Tecfidera), and teriflunomide (Aubagio) from four Swedish studies, one French study, and one international study were reported during a poster session on long-term treatment monitoring at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
The IMSE 1 study with natalizumab
The Immunomodulation and Multiple Sclerosis Epidemiology (IMSE) studies are Swedish postmarketing surveillance studies that were started with the launch of various DMTs in Sweden: natalizumab since 2006 (IMSE 1), fingolimod in 2015 (IMSE 2), alemtuzumab in 2014 (IMSE 3), and dimethyl fumarate in 2014 (IMSE 5).
“Postmarketing surveillance is important for determination of long-term safety and effectiveness in a real-world setting,” Stina Kågström and her associates observed in their poster reporting some findings of the IMSE 1 study with natalizumab (Mult Scler. 2018;24[S2]:699-700, Abstract P1232).
Ms. Kågström of the department of clinical neuroscience at the Karolinska Institute in Stockholm and her colleagues reported that data on 3,108 patients who were seen at 54 Swedish clinics had been collated via the nationwide Swedish Quality Registry for Neurological Care (NEUROreg). NEUROreg started out as an MS register but has since widened its remit to include other neurologic diagnoses.
For the IMSE 1 study, prospectively recorded data regarding natalizumab treatment, adverse events, JC-virus (JCV) status and clinical effectiveness measures were obtained from NEUROreg for 2,225 women and 883 men. Just over one-third (37%, n = 1,150) were still receiving natalizumab at the time of the analysis.
The mean age at which natalizumab was started was 39 years, with treatment primarily given for RRMS (81% of patients) and less often for secondary progressive multiple sclerosis (SPMS, 15%) and rarely for other types of progressive MS. The mean treatment duration was just under 4 years (47.6 months).
JCV testing was introduced in 2011 in Sweden, and this “has led to fewer treated JCV-positive patients,” the IMSE 1 study investigators reported. “This likely explains a reduced incidence of PML [progressive multifocal leukoencephalopathy],” they suggested. There were nine PML cases diagnosed in Sweden from 2008 to the data cut-off point in 2018, one of which was fatal.
JCV status from 2011 onward was available for 1,269 patients, of whom 39% were JCV positive and 61% were JCV negative. The overall drug survival rate was 72% for JCV-negative and 14% for JCV-positive patients. Improved health status was seen, as measured by the Expanded Disability Status Scale (EDSS), the Multiple Sclerosis Severity Score (MSSS), and the physical and psychological Multiple Sclerosis Impact Scale–29 (MSIS-29) components.
A total of 644 of 1,269 patients discontinued treatment with natalizumab at some point, of whom 67% discontinued because of being JCV positive. The main reason for discontinuation in JCV-negative patients was pregnancy or planning a pregnancy (38%), with lack of effect (10%) and adverse events (11%) as other key reasons for stopping natalizumab.
Ms. Kågström and her associates concluded that natalizumab was “generally well tolerated with sustained effectiveness.”
The IMSE 2 study with fingolimod
Data on the long-term safety and efficacy of fingolimod were reported from the IMSE 2 study (Mult Scler. 2018;24[S2]:696-7, Abstract P1228). Lead author Anna Fält, also of the Karolinska Institute, and her associates analyzed data for 1,634 patients who had been treated with fingolimod from June 2015 to September 2018.
Most patients were older than 30 years (79%), and those aged 30 and older were predominantly female (69%), had an RRMS diagnosis (88%), and been treated for a mean of about 3 years (37 months). A total of 829 were being treated with fingolimod at the time of the analysis, with 844 having discontinued treatment at some point. The main reason for discontinuing treatment with fingolimod was a lack of effect (42% of cases) or an adverse effect (34%). The IMSE 2 study authors reported in their abstract that most patients were switched to rituximab after discontinuing fingolimod.
The number of relapses per 1,000 patient-years was reduced by fingolimod treatment from 280 to 82, comparing before and during treatment for all age groups studied. Relapse rate dropped from 694 per 1,000 patient-years before treatment to 138 during treatment in patients aged 20 years or younger, from 454 to 122 in those aged 21-30 years, and from 257 to 72 in those older than 31 years.
After 1 year of treatment, improvements were seen in the health status of patients as measured by various scales, including the EDSS, MSSS, MSIS-29 Physical, and MSIS-29 Psychological. When the researchers analyzed data by age groups, significant improvements were seen in patients aged 21-30 years and older than 30 years.
Ninety nonserious and 62 serious adverse events were reported in fingolimod-treated patients during the time of analysis. Of the latter, 13 serious adverse events involved cardiac disorders, 12 neoplasms, and 10 infections and infestations.
Overall, the IMSE 2 study investigators said that fingolimod was generally tolerable and reduced disease activity in MS.
French experience with fingolimod: The VIRGILE study
Real-world data on the long-term safety and efficacy of fingolimod in France from the VIRGILE study were reported by Christine Lebrun-Frenay, MD, PhD, and her associates (Mult Scler. 2018;24[S2]:698-9, Abstract P1231).
Dr. Lebrun-Frenay of Pasteur 2 Hospital in Nice and her coauthors noted that VIRGILE study included patients starting treatment with fingolimod between January 2014 and February 2016. A total of 1,047 patients were included, and another 330 patients treated with natalizumab were included at the behest of the French health authorities.
The annualized relapse rate after 2 years of follow-up was 0.30 in the fingolimod group. Dr. Lebrun-Frenay and her colleagues noted: “The 3-year data from this interim analysis provide evidence for sustained efficacy of fingolimod.” Indeed, they report that almost 60% of patients did not relapse and 64% had no worsening of disease. On average, EDSS was stable during the 3-year follow-up period.
“Safety and tolerability profiles of fingolimod were in line with previous clinical experience, with lymphopenia being the most frequent AE [adverse event] reported,” they added.
The IMSE 3 study with alemtuzumab
Long-term experience with alemtuzumab as a treatment for RRMS in the real-world setting is more limited as it only became available for use for this indication in 2014, but some insight is provided by the results of the IMSE 3 study (Mult Scler. 2018;24[S2]:706-7, Abstract P1240).
In total, there were 113 patients treated with alemtuzumab; the vast majority (94%) had RRMS and were aged a mean of 34 years at the start of treatment. Treatment was for more than 12 months in 101 patients, more than 24 months in 86 patients, and more than 36 months in 36 patients.
“In patients treated for at least 12 months, significant improvements were seen in several clinical parameters,” Dr. Fält and her associates observed in their poster at ECTRIMS. The mean baseline and 12-month values for the EDSS were 2.0 and 1.6, and for the MSSS they were 3.46 and 2.61. The mean baseline and 12-month values for the MSIS-29 Psychological subscale were 35.1 and 30.8, respectively, and for MSIS-29 Physical they were 22.7 and 17.7.
Overall, there were 14 nonserious and 11 serious adverse events, the most common of which were infections and infestations, metabolism and nutrition disorders, and immune system disorders.
“A longer follow-up period is needed to assess the real-world effectiveness and safety of alemtuzumab,” the IMSE 3 study authors noted.
The IMSE 5 study with dimethyl fumarate
Similarly, the authors of the IMSE 5 study (Mult Scler. 2018;24[S2]:701-2, Abstract 1234) concluded that a longer follow-up period is need to assess the real-world effectiveness of dimethyl fumarate. Selin Safer Demirbüker, also of the Karolinska Institute, and her associates looked at data on 2,108 patients treated with dimethyl fumarate between March 2014 and April 2018, of whom 1,150 were still receiving treatment at the time of their assessment.
The mean age of patients at the start of treatment was 41 years, 91% had RRMS, and 73% were female. The mean treatment duration was 22.3 months. The majority of patients (n = 867) had been previously treated with interferon and glatiramer acetate (Copaxone) prior to dimethyl fumarate, with 538 being naive to treatment.
“Dimethyl fumarate seems to have a positive effect for patients remaining on treatment,” wrote Ms. Safer Demirbüker and her colleagues. The overall 1-year drug survival reported in their abstract was 74%. Their poster showed a lower 2-year drug survival rate of 63.5% for men and 56.4% for women.
“Swedish patients show cognitive, psychological, and physical benefits after 2 or more years of treatment,” the IMSE 5 study authors further noted. Mean EDSS, MSSS, and MSIS-29 Psychological values all fell from baseline to 2 years.
Overall, 958 (47%) of patients discontinued treatment with dimethyl fumarate at some point, primarily (in 52% of cases) because of adverse events or lack of effect (29% of cases). Most patients (39%) switched to rituximab (15% had no new treatment registered), but 35% of patients continued treatment for 3 or more years.
Twelve-year follow-up of teriflunomide shows continued efficacy, safety
Mark Freedman, MD, of the University of Ottawa and the Ottawa Hospital Research Institute and his associates reported long-term follow-up data on the efficacy and safety of teriflunomide (Aubagio) in relapsing forms of MS (Mult Scler. 2018;24[S2]:700-1, Abstract P1233). After up to 12 years’ follow up, teriflunomide 14 mg was associated with an overall annualized relapse rate of 0.228.
Yearly annualized relapse rates were “low and stable,” Dr. Freedman and his coauthors from the United States, Spain, Italy, France, Germany, England, the Republic of Korea, and Australia noted in their poster.
“As of August 2018, over 93,000 patients were being treated with teriflunomide,” the authors stated. This represented a real-world exposure of approximately 186,000 patient-years up to December 2017, they added.
For the analysis, data from one phase 2 study and three phase 3 studies (TEMSO, TOWER, and TENERE) and their long-term extension studies were pooled. In all, there were 1,696 patients treated with 14 mg of teriflunomide in these studies.
Annualized relapse rates ranged from 0.321 in the first year of follow-up in the studies to 0.080 by the 12th year. The proportions of patients remaining relapse free “were high and stable (ranging from 0.75 in year 1 to 0.93 in years 8 and 9).” EDSS scores were 2.57 at baseline and 2.27 at year 12.
Importantly, no new safety signals were reported, Dr. Freedman and his colleagues wrote, adding that most adverse events were mild to moderate in severity.
Taken together, “these data demonstrate the long-term efficacy and safety of teriflunomide,” they concluded.

Twelve-year follow-up of teriflunomide shows continued efficacy, safety
Mark Freedman, MD, of the University of Ottawa and the Ottawa Hospital Research Institute and his associates reported long-term follow-up data on the efficacy and safety of teriflunomide (Aubagio) in relapsing forms of MS (Mult Scler. 2018;24[S2]:700-1, Abstract P1233). After up to 12 years’ follow up, teriflunomide 14 mg was associated with an overall annualized relapse rate of 0.228.
Yearly annualized relapse rates were “low and stable,” Dr. Freedman and his coauthors from the United States, Spain, Italy, France, Germany, England, the Republic of Korea, and Australia noted in their poster.

For the IMSE 1 study, prospectively recorded data regarding natalizumab treatment, adverse events, JC-virus (JCV) status and clinical effectiveness measures were obtained from NEUROreg for 2,225 women and 883 men. Just over one-third (37%, n = 1,150) were still receiving natalizumab at the time of the analysis.
The mean age at which natalizumab was started was 39 years, with treatment primarily given for RRMS (81% of patients) and less often for secondary progressive multiple sclerosis (SPMS, 15%) and rarely for other types of progressive MS. The mean treatment duration was just under 4 years (47.6 months).
JCV testing was introduced in 2011 in Sweden, and this “has led to fewer treated JCV-positive patients,” the IMSE 1 study investigators reported. “This likely explains a reduced incidence of PML [progressive multifocal leukoencephalopathy],” they suggested. There were nine PML cases diagnosed in Sweden from 2008 to the data cut-off point in 2018, one of which was fatal.
JCV status from 2011 onward was available for 1,269 patients, of whom 39% were JCV positive and 61% were JCV negative. The overall drug survival rate was 72% for JCV-negative and 14% for JCV-positive patients. Improved health status was seen, as measured by the Expanded Disability Status Scale (EDSS), the Multiple Sclerosis Severity Score (MSSS), and the physical and psychological Multiple Sclerosis Impact Scale–29 (MSIS-29) components.
A total of 644 of 1,269 patients discontinued treatment with natalizumab at some point, of whom 67% discontinued because of being JCV positive. The main reason for discontinuation in JCV-negative patients was pregnancy or planning a pregnancy (38%), with lack of effect (10%) and adverse events (11%) as other key reasons for stopping natalizumab.
Ms. Kågström and her associates concluded that natalizumab was “generally well tolerated with sustained effectiveness.”
The IMSE 2 study with fingolimod
Data on the long-term safety and efficacy of fingolimod were reported from the IMSE 2 study (Mult Scler. 2018;24[S2]:696-7, Abstract P1228). Lead author Anna Fält, also of the Karolinska Institute, and her associates analyzed data for 1,634 patients who had been treated with fingolimod from June 2015 to September 2018.
Most patients were older than 30 years (79%), and those aged 30 and older were predominantly female (69%), had an RRMS diagnosis (88%), and been treated for a mean of about 3 years (37 months). A total of 829 were being treated with fingolimod at the time of the analysis, with 844 having discontinued treatment at some point. The main reason for discontinuing treatment with fingolimod was a lack of effect (42% of cases) or an adverse effect (34%). The IMSE 2 study authors reported in their abstract that most patients were switched to rituximab after discontinuing fingolimod.
The number of relapses per 1,000 patient-years was reduced by fingolimod treatment from 280 to 82, comparing before and during treatment for all age groups studied. Relapse rate dropped from 694 per 1,000 patient-years before treatment to 138 during treatment in patients aged 20 years or younger, from 454 to 122 in those aged 21-30 years, and from 257 to 72 in those older than 31 years.
After 1 year of treatment, improvements were seen in the health status of patients as measured by various scales, including the EDSS, MSSS, MSIS-29 Physical, and MSIS-29 Psychological. When the researchers analyzed data by age groups, significant improvements were seen in patients aged 21-30 years and older than 30 years.
Ninety nonserious and 62 serious adverse events were reported in fingolimod-treated patients during the time of analysis. Of the latter, 13 serious adverse events involved cardiac disorders, 12 neoplasms, and 10 infections and infestations.
Overall, the IMSE 2 study investigators said that fingolimod was generally tolerable and reduced disease activity in MS.
French experience with fingolimod: The VIRGILE study
Real-world data on the long-term safety and efficacy of fingolimod in France from the VIRGILE study were reported by Christine Lebrun-Frenay, MD, PhD, and her associates (Mult Scler. 2018;24[S2]:698-9, Abstract P1231).
Dr. Lebrun-Frenay of Pasteur 2 Hospital in Nice and her coauthors noted that VIRGILE study included patients starting treatment with fingolimod between January 2014 and February 2016. A total of 1,047 patients were included, and another 330 patients treated with natalizumab were included at the behest of the French health authorities.
The annualized relapse rate after 2 years of follow-up was 0.30 in the fingolimod group. Dr. Lebrun-Frenay and her colleagues noted: “The 3-year data from this interim analysis provide evidence for sustained efficacy of fingolimod.” Indeed, they report that almost 60% of patients did not relapse and 64% had no worsening of disease. On average, EDSS was stable during the 3-year follow-up period.
“Safety and tolerability profiles of fingolimod were in line with previous clinical experience, with lymphopenia being the most frequent AE [adverse event] reported,” they added.
The IMSE 3 study with alemtuzumab
Long-term experience with alemtuzumab as a treatment for RRMS in the real-world setting is more limited as it only became available for use for this indication in 2014, but some insight is provided by the results of the IMSE 3 study (Mult Scler. 2018;24[S2]:706-7, Abstract P1240).
In total, there were 113 patients treated with alemtuzumab; the vast majority (94%) had RRMS and were aged a mean of 34 years at the start of treatment. Treatment was for more than 12 months in 101 patients, more than 24 months in 86 patients, and more than 36 months in 36 patients.
“In patients treated for at least 12 months, significant improvements were seen in several clinical parameters,” Dr. Fält and her associates observed in their poster at ECTRIMS. The mean baseline and 12-month values for the EDSS were 2.0 and 1.6, and for the MSSS they were 3.46 and 2.61. The mean baseline and 12-month values for the MSIS-29 Psychological subscale were 35.1 and 30.8, respectively, and for MSIS-29 Physical they were 22.7 and 17.7.
Overall, there were 14 nonserious and 11 serious adverse events, the most common of which were infections and infestations, metabolism and nutrition disorders, and immune system disorders.
“A longer follow-up period is needed to assess the real-world effectiveness and safety of alemtuzumab,” the IMSE 3 study authors noted.
The IMSE 5 study with dimethyl fumarate
Similarly, the authors of the IMSE 5 study (Mult Scler. 2018;24[S2]:701-2, Abstract 1234) concluded that a longer follow-up period is need to assess the real-world effectiveness of dimethyl fumarate. Selin Safer Demirbüker, also of the Karolinska Institute, and her associates looked at data on 2,108 patients treated with dimethyl fumarate between March 2014 and April 2018, of whom 1,150 were still receiving treatment at the time of their assessment.
The mean age of patients at the start of treatment was 41 years, 91% had RRMS, and 73% were female. The mean treatment duration was 22.3 months. The majority of patients (n = 867) had been previously treated with interferon and glatiramer acetate (Copaxone) prior to dimethyl fumarate, with 538 being naive to treatment.
“Dimethyl fumarate seems to have a positive effect for patients remaining on treatment,” wrote Ms. Safer Demirbüker and her colleagues. The overall 1-year drug survival reported in their abstract was 74%. Their poster showed a lower 2-year drug survival rate of 63.5% for men and 56.4% for women.
“Swedish patients show cognitive, psychological, and physical benefits after 2 or more years of treatment,” the IMSE 5 study authors further noted. Mean EDSS, MSSS, and MSIS-29 Psychological values all fell from baseline to 2 years.
Overall, 958 (47%) of patients discontinued treatment with dimethyl fumarate at some point, primarily (in 52% of cases) because of adverse events or lack of effect (29% of cases). Most patients (39%) switched to rituximab (15% had no new treatment registered), but 35% of patients continued treatment for 3 or more years.
Twelve-year follow-up of teriflunomide shows continued efficacy, safety
Mark Freedman, MD, of the University of Ottawa and the Ottawa Hospital Research Institute and his associates reported long-term follow-up data on the efficacy and safety of teriflunomide (Aubagio) in relapsing forms of MS (Mult Scler. 2018;24[S2]:700-1, Abstract P1233). After up to 12 years’ follow up, teriflunomide 14 mg was associated with an overall annualized relapse rate of 0.228.
Yearly annualized relapse rates were “low and stable,” Dr. Freedman and his coauthors from the United States, Spain, Italy, France, Germany, England, the Republic of Korea, and Australia noted in their poster.
“As of August 2018, over 93,000 patients were being treated with teriflunomide,” the authors stated. This represented a real-world exposure of approximately 186,000 patient-years up to December 2017, they added.
For the analysis, data from one phase 2 study and three phase 3 studies (TEMSO, TOWER, and TENERE) and their long-term extension studies were pooled. In all, there were 1,696 patients treated with 14 mg of teriflunomide in these studies.
Annualized relapse rates ranged from 0.321 in the first year of follow-up in the studies to 0.080 by the 12th year. The proportions of patients remaining relapse free “were high and stable (ranging from 0.75 in year 1 to 0.93 in years 8 and 9).” EDSS scores were 2.57 at baseline and 2.27 at year 12.
Importantly, no new safety signals were reported, Dr. Freedman and his colleagues wrote, adding that most adverse events were mild to moderate in severity.
Taken together, “these data demonstrate the long-term efficacy and safety of teriflunomide,” they concluded.
