– Last December, the Food and Drug Administration approved nusinersen (Spinraza) as the only treatment for spinal muscular atrophy (SMA) based in part on startling interim results from a study in infants that ended early so all participants could get access to the drug.

Now the final study results are in, and they’re even more impressive: Patients who took the drug were less than half as likely to die as were those in a sham control group, and motor function improved in more than half of infants who took the medication, compared with none in the sham group.

The findings are “incredibly exciting,” said Charlotte J. Sumner, MD, in a discussant presentation at the annual meeting of the American Academy of Neurology. “The data teaches us that this drug is efficacious.”

However, Dr. Sumner, professor of neurology and neuroscience at Johns Hopkins University, Baltimore, cautioned that the drug is tremendously expensive, challenging to administer, and there are several questions about its use that remain unanswered.

SMA is most often caused by mutations in the SMN1 gene, leading to a loss of the protein called survival motor neuron (SMN), which is essential for the survival of motor neurons, except for a small amount produced from the SMN2 gene. The loss of motor neurons in the spinal cord and brainstem leads to weakness and atrophy of muscles used for crawling, walking, sitting up, controlling head movement, and in severe cases, breathing and swallowing. It affects an estimated 1 in 6,000 newborns and is the most common genetic cause of death in infants. Nusinersen is a antisense oligonucleotide that promotes transcription of the full-length SMN protein from the SMN2 gene.

At the AAN meeting, investigators presented the final results of two nusinersen phase III studies as well as interim data from a separate phase II trial.

The ENDEAR trial, a randomized, double-blind, sham-procedure controlled study, assigned 80 patients to 12-mg scaled equivalent doses of nusinersen delivered intrathecally (four doses over 2 months, then one every 4 months) and 41 to a sham procedure (a needle prick in the lower back). The subjects, aged 30-252 days at first dose, underwent 13 months of treatment and follow-up.

Researchers presented an end-of-study analysis of 110 subjects. They found that 51% of those who received the drug were “motor milestone responders” – meaning they had more modified Hammersmith Infant Neurological Examination Section 2 categories with improvement than worsening – compared with 41% at the interim analysis (P less than .0001). None of the sham group patients improved.

The patients treated with nusinersen lived longer: 39% of those in the sham procedure group died, compared with 16% of those in the nusinersen group (hazard ratio, 0.372; P = .0041). Event-free survival (survival without permanent ventilation) was also better in those who received the drugs: 61% in those who took nusinersen, compared with 32% in those who did not (HR, 0.53; P = .0046)

Also, 71% of those treated with the drug were considered responders at day 183 onward based on an improvement of 4 or more points on the Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders scale, whereas the response rate was only 3% in the sham group (P less than .0001).

The study authors report that nusinersen was well tolerated with adverse events that “were consistent with those expected in the general population of infants with SMA.” No adverse events were linked to the nusinersen treatment.

Researchers also presented the end-of-study results of the phase III CHERISH trial of 126 patients aged 2-12 years with later-onset SMA who could sit up but not walk. All participants were believed to have a life expectancy of at least 2 years.

The trial is a multicenter, randomized, double-blind, sham-procedure controlled study. The 84 subjects who received the drug improved an average of 3.9 points by the end of study (15 months) on the Hammersmith Functional Motor Scale Expanded score, a measurement of motor function in children with SMA (P = .0000001). The 42 children who received the sham treatment (a small needle prick on the lower back) declined by an average of 1.0 point.

Researchers report that children taking the drug had fewer adverse events, and most were not related to the drug itself.

All surviving participants who completed nusinersen investigational studies are being enrolled in the SHINE open-label extension trial.

Also at the AAN meeting, researchers released interim phase II results from the NURTURE trial, an open-label study of nusinersen in patients with diagnosed but presymptomatic SMA. The study, which is expected to be completed in 2022, recruited participants up to the age of 6 weeks.

The 20 enrolled infants were all alive at a median study period of 317.5 days, and none required assistance with respiration.

In terms of motor function and growth, most were making gains “generally consistent with normal development such as head control, independent sitting, standing and walking independently, as measured by validated scales,” according to a statement released by Biogen.

Three patients developed adverse events that may have been drug related, but the events were resolved and they remained in the trial.

In Dr. Sumner’s discussant presentation on the ENDEAR study, she cautioned that it’s still not known how much older patients with SMA will benefit from the drug treatment. It’s possible that younger patients may gain motor function while older patients will maintain what they have, she said.

In addition, it seems that “certain body segments may respond more robustly than some others. It’s possible that an infant may improve limb strength quite robustly but not lumbar strength.”

She pointed out other questions: Can the drug, which is difficult to administer, be stopped at some point? “We do think of SMA as a disease of development,” she said. “Maybe after development is finished we can withdraw the drug.”

Then there’s the issue of cost and whether insurers are willing to cover the drug. As Dr. Sumner pointed out, the drug is $125,000 per dose and $750,000 over the first year, then $325,000 a year.

It is clear, however, that “the early and efficient diagnosis of SMA is really important, particularly for infantile SMA,” she said. “Time is motor function.”

The studies were funded by Ionis Pharmaceuticals and Biogen. Dr. Sumner reports serving as a consultant for Biogen, Ionis, Avexis, and Roche. She has served on scientific advisory boards for the Cure SMA, SMA Foundation, and Muscular Dystrophy Association nonprofit foundations.

PATH study: Subcutaneous immunoglobulin safe, effective for CIDP maintenance

– Subcutaneously administered immunoglobulin was effective, well tolerated, and preferred over intravenous administration as maintenance treatment for chronic inflammatory demyelinating polyneuropathy in the phase III, randomized, placebo-controlled PATH study.

The 172-patient trial tested a high and low dose of subcutaneous immunoglobulin (SCIg) over the course of 25 weeks to determine their effect on the primary outcome of chronic inflammatory demyelinating polyneuropathy (CIDP) relapse or withdrawal from treatment for any reason. In this evaluation of using SCIg for maintenance of response, relapses or treatment withdrawal occurred in 63% with placebo, 39% with low dose SCIg (0.2 g/kg weekly), and 33% with high dose (0.4 g/kg weekly), Ivo N. van Schaik, MD, reported at the annual meeting of the American Academy of Neurology.

Patients in the trial had received at lease one dose of intravenous immunoglobulin (IVIg) within 8 weeks before screening. They then underwent a screening period first, followed by an IgG dependency period of up to 12 weeks to test for ongoing need for IgG. The patients who experienced CIDP relapse during this test period were administered a standardized IVIG regimen during a 10- to 13-week restabilization period, and those who improved and maintained their Inflammatory Neuropathy Cause and Treatment (INCAT) score continued to the randomized subcutaneous treatment period of the study.

CIDP relapse occurred in 56% of patients in the placebo group, compared with 33% in the low- and 19% in the high-dose SCIg groups, said Dr. van Schaik of the University of Amsterdam (the Netherlands).

“Both [SCIg] doses were effective in preventing relapse. The higher dose performed better than the lower dose, but the difference was not statistically significant,” he said.

Both doses were significantly more effective than placebo.

Study participants were adults with definite or probable CIDP enrolled from 69 neuromuscular centers worldwide between March 2012 and November 2015. Weekly self-administered subcutaneous infusions of SCIg (IgPro20Hizentra) were performed during 1 or 2 consecutive days in two separate sessions using special infusion pumps. Patients reported that learning the self-administration technique was easy, Dr. van Schaik said.

Adverse effects included mainly local reactions, which occurred in 19% of patients, but these were generally mild and rarely resulted in therapy discontinuation, and local reactions decreased considerably over time, he said, noting that systemic effects are reduced with SCIg vs. IVIg.

Subcutaneous administration of immunoglobulin is not new. In fact, it has been used successfully in patients with immunodeficiency syndromes for more than 2 decades and can increase patient autonomy and reduce costs by reducing hospital and infusion center visits, but this is the first study to assess efficacy, safety, and tolerability of this approach in an adequately powered, randomized, clinical trial, he said.

“Subcutaneous immunoglobulin can be used ... for maintenance treatment of patients with CIDP,” he concluded, adding that weekly doses of 0.2-0.4 g/kg are supported by these data, and that maintenance doses should be individualized based on patient factors and previous IVIg dose and frequency.

The PATH study was sponsored by CSL-Behring. Dr. van Schaik chairs a steering committee for CSL-Behring and received departmental honoraria for serving on scientific advisory boards for CSL-Behring, Baxalta, and UCB. He also received speakers fees from CSL-Behring and Kedrion.

FDA approves first new drug for ALS in decades

The Food and Drug Administration approved the antioxidant drug edaravone on May 5 for the treatment of amyotrophic lateral sclerosis, making it only the second drug ever to be approved by the agency for the motor neuron disease.

The FDA granted approval for edaravone, to be marketed by Mitsubishi Tanabe Pharma America under the brand name Radicava, through its orphan drug pathway, which is meant for drugs used to treat rare diseases or conditions. The Centers for Disease Control and Prevention estimates that amyotrophic lateral sclerosis (ALS) affects 12,000-15,000 Americans.

“After learning about the use of edaravone to treat ALS in Japan, we rapidly engaged with the drug developer about filing a marketing application in the United States,” said Eric Bastings, MD, deputy director of the division of neurology products in the FDA’s Center for Drug Evaluation and Research, said in the agency’s announcement. “This is the first new treatment approved by the FDA for ALS in many years, and we are pleased that people with ALS will now have an additional option.”

Mitsubishi Tanabe Pharma America demonstrated the efficacy of edaravone in a 6-month trial of 137 Japanese ALS patients. At 24 weeks, individuals who received edaravone had less decline on a clinical assessment of daily functioning, the ALS Functional Rating Scale-Revised (ALSFRS-R), compared with those who received a placebo. The difference in decline between the two groups was 33%, or a total of 2.49 points, on the ALSFRS-R. Most of the patients in the study also received the only other drug approved for ALS, riluzole (Rilutek).

Edaravone is thought to confer neuroprotection in part through its free radical–scavenging activity.

The adverse events most often reported by clinical trial participants who took edaravone included bruising and gait disturbance. The FDA also warned that edaravone is associated with hives, swelling, or shortness of breath, and allergic reactions to an ingredient in the drug, sodium bisulfite, which may cause anaphylactic symptoms that can be life-threatening in people with sulfite sensitivity.

The drug is administered via intravenous infusion with an initial treatment cycle of daily dosing for 14 days, followed by a 14-day drug-free period. Subsequent treatment cycles consist of dosing on 10 of 14 days, followed by 14 days drug-free.

Mitsubishi Tanabe Pharma America said in a statement that it has created a patient access program called Searchlight Support for people with ALS who are prescribed the drug. The program provides personal case management, reimbursement support, and 24/7 clinical support.

In 2015, edaravone was approved for use as a treatment for ALS in Japan and South Korea.

The Food and Drug Administration approved the antioxidant drug edaravone on May 5 for the treatment of amyotrophic lateral sclerosis, making it only the second drug ever to be approved by the agency for the motor neuron disease.

The FDA granted approval for edaravone, to be marketed by Mitsubishi Tanabe Pharma America under the brand name Radicava, through its orphan drug pathway, which is meant for drugs used to treat rare diseases or conditions. The Centers for Disease Control and Prevention estimates that amyotrophic lateral sclerosis (ALS) affects 12,000-15,000 Americans.

“After learning about the use of edaravone to treat ALS in Japan, we rapidly engaged with the drug developer about filing a marketing application in the United States,” said Eric Bastings, MD, deputy director of the division of neurology products in the FDA’s Center for Drug Evaluation and Research, said in the agency’s announcement. “This is the first new treatment approved by the FDA for ALS in many years, and we are pleased that people with ALS will now have an additional option.”

Mitsubishi Tanabe Pharma America demonstrated the efficacy of edaravone in a 6-month trial of 137 Japanese ALS patients. At 24 weeks, individuals who received edaravone had less decline on a clinical assessment of daily functioning, the ALS Functional Rating Scale-Revised (ALSFRS-R), compared with those who received a placebo. The difference in decline between the two groups was 33%, or a total of 2.49 points, on the ALSFRS-R. Most of the patients in the study also received the only other drug approved for ALS, riluzole (Rilutek).

Edaravone is thought to confer neuroprotection in part through its free radical–scavenging activity.

The adverse events most often reported by clinical trial participants who took edaravone included bruising and gait disturbance. The FDA also warned that edaravone is associated with hives, swelling, or shortness of breath, and allergic reactions to an ingredient in the drug, sodium bisulfite, which may cause anaphylactic symptoms that can be life-threatening in people with sulfite sensitivity.

VIDEO: About 1 in 20 ALS patients in Washington state chose assisted suicide

Article Type

Fri, 01/18/2019 - 16:43

BOSTON – A new study estimates that 3.4%-6.7% of amyotrophic lateral sclerosis (ALS) patients in Washington state sought to commit physician-assisted suicide over a 5-year period.

 

The rate is many times higher than that among cancer patients in the state, researchers found. They also discovered that ALS patients were significantly more likely than were other terminally ill people to use the deadly medication after getting prescriptions for it.

The findings appear to reflect the unique hopelessness facing ALS patients. “They’re not afforded as much denial of decline and death as are patients with other terminal illnesses,” said Linda Ganzini, MD, MPH, a professor of psychiatry and medicine at Oregon Health & Science University, Portland, who has studied end of life in ALS patients.

“Many cancer patients, even in the final days of life, receive treatments that they hope will extend their lives,” she said in an interview after reviewing the study findings. “In contrast, treatments for ALS are minimally effective.”

Physician-assisted suicide is legal in California, Colorado, the District of Columbia, Montana, Oregon, Vermont, and Washington.

A team led by Leo H. Wang, MD, PhD, of the University of Washington, Seattle, examined the medical records of 39 ALS patients who sought medication to end their lives at three hospitals in Seattle from March 2009 to Dec. 31, 2014.

Washington’s Death with Dignity (DWD) law, which went into effect in 2009, allows physicians to prescribe lethal medication if the patient has a terminal illness and a prognosis of less than 6 months to live as judged by two physicians.

The researchers reported their findings, a follow-up to a previous study (Neurology. 2016 Nov 15;87[20]:2117-22), at the annual meeting of the American Academy of Neurology.

The median age of the ALS patients at symptom onset was 64 (range, 42-83), and a median of 712 days passed (range, 207-2,407) from the date of diagnosis to date of prescription for lethal medication.

The median time from prescription to death was 22 days, with at least one patient dying immediately (range, 0-386 days). All 39 patients had limb involvement, and 82%-92% had bulbar involvement, dysarthria, dysphagia, and/or dyspnea.

The researchers estimate that 3.4%-6.7% of 1,146 ALS patients in Washington who died over the time period of the study sought a physician-assisted death. The 3.4% figure assumes that the 39 patients at the three hospitals make up all the ALS patients who received medication prescriptions. The 6.7% figure assumes that all patients with neurodegenerative disease who sought DWD in the state over that period had ALS.

“Similarly, 5% (92 of 1,795) of Oregon ALS patient who died sought medication under DWD between 1998 and 2014,” Dr. Wang said. “This is slightly increased compared to the percentage during the first decade, following enactment of the Oregon law (1998-2007), when 2.7% (26 of 962) of ALS patients died using DWD medication.”

Using Washington state data, researchers also estimated that 0.6% of 73,319 cancer patients and 0.2% of 298,178 people in the state who died of all causes sought DWD over the study period.

A total of 30 (77%) ALS patients who received the deadly prescriptions chose to take them, compared with 67% of all-cause patients who took advantage of the DWD law and 60% of cancer patients.

All 30 patients died. The nine who chose to not take the prescribed medication died after a median of 76 days. The patients who did not take the medication were more likely to be married (88% vs. 69%), to be college educated (100% vs. 74%), and to use a motorized wheelchair (78% vs. 31%).

Those who chose to not take the prescribed medication were also less motivated by loss of dignity (63% vs. 93% among those who took the medication) and by being a burden on others (25% vs. 66%). They were more likely to identify themselves as religious (80% vs. 35%).

Multiple factors may explain why ALS patients made different choices regarding the deadly drugs, lead study author Dr. Wang said in an interview. “We thought that the loss of communication may have played a role based on our finding, as most patients who followed through had more substantial trouble speaking,” he said. “For the patients who ultimately did not choose to take the medication, we found more of them had stronger religious beliefs than those who did not.”

As for pain, he reported that it was not a major issue. “Only about 10% of ALS patients were worried about pain, as opposed to 30% of the general Death with Dignity patients,” he said.

Dr. Ganzini noted that some patients who seek the prescribed drugs “want reassurance that, if their quality of life becomes unbearable, they have the option of physician-assisted death. But, they continue to cope and find reasons to live. As such, they ultimately die of their disease without taking the medications. Others lose the ability to ingest the medications, often because of sudden worsening of their disease.”

Key clinical point: ALS patients are much more likely than are cancer patients to seek physician-assisted suicide, and they’re more likely to take deadly medication once it’s prescribed.

Major finding: An estimated 3.4%-6.7% of ALS patients in Washington state sought physician-assisted death, and 77% took the prescribed deadly medication, a higher rate than all-cause (67%) and cancer patients (60%).

Data source: Analysis of 39 ALS patients who sought deadly medication from three Seattle hospitals from March 2009 to Dec. 31, 2014.

Disclosures: No specific funding was reported, and Dr. Wang had no disclosures.

– Some of the most influential clinical research reports coming out of the annual meeting of the American Academy of Neurology raise questions on how neurologists will strike a balance between the improved efficacy and safety of drugs in new therapeutic classes and their affordability for patients.

Natalia Rost, MD, vice chair of the AAN Science Committee, discussed phase III clinical trials (ARISE and STRIVE) in episodic migraine with erenumab, an investigational humanized monoclonal antibody against calcitonin gene-related peptide receptor; phase III clinical trials (ENDEAR and CHERISH) of the antisense oligonucleotide drug nusinersen (Spinraza) that was approved by the Food and Drug Administration for spinal muscular atrophy in late 2016; as well as phase III trials of a pharmaceutical-grade extract of the cannabis-derived compound cannabidiol in patients with Dravet syndrome and Lennox-Gastaut syndrome.

Erenumab and nusinersen are “disease-specific targeted biologics” that have been developed over decades to target a specific disease pathway, and hence translate into high prices, Dr. Rost said in a video interview at the meeting.

“How you value the cost of a drug against improvement in a physiological outcome is very difficult to measure,” she noted, for relatively small gains in reducing migraine days per month and improvements in functional outcome and disability against placebo.

But this calculation is different with the potentially lifesaving effects of nusinersen for spinal muscular atrophy patients, in which “we’re not talking about days of improvement, we’re talking about days of life,” said Dr. Rost, director of acute stroke services at Massachusetts General Hospital, Boston. “And so that becomes an ethical dilemma in terms of the cost of administration, who is paying for the drug, and how this is covered. Whom do you offer treatment to?”

The development of cannabidiol as a potential adjunctive treatment for Dravet and Lennox-Gastaut syndromes is a welcome addition to the armamentarium against these conditions, Dr. Rost added, because it offers an alternative to the unregulated use of herbal medications and supplements – particularly cannabis in its various forms – that patients ask about but are difficult to dose consistently and to ensure a pharmaceutical-grade level of purity.

Mon, 01/07/2019 - 12:53

 

A variety of plenary and emerging science sessions at this year’s annual meeting of the American Academy of Neurology in Boston will highlight clinical research efforts to treat children with spinal muscular atrophy.

At the Hot Topics Plenary Session on April 22, Claudia A. Chiriboga, MD, of Columbia University, New York, will discuss the results of clinical trials involving antisense oligonucleotide treatments for spinal muscular atrophy (SMA), including the recently approved nusinersen (Spinraza), which promotes transcription of the full-length survival motor neuron (SMN) protein from the SMN2 gene.

In the first of two reports on new clinical research about nusinersen, Nancy L. Kuntz, MD, of Ann & Robert H. Lurie Children’s Hospital of Chicago will present the initial interim efficacy and safety findings from the phase III international ENDEAR study on April 24 at the Contemporary Clinical Issues Plenary Session. The study of 122 infants with SMA is comparing intrathecal administration of nusinersen against a sham procedure of a small needle prick on the lower back to look for differences at day 402 in the primary outcome of the percentage of patients who attain motor milestones as assessed by section 2 of the Hammersmith Infant Neurological Examination or the time to death or need for respiratory intervention. Charlotte J. Sumner, MD, of Johns Hopkins University, Baltimore, will discuss the study following Dr. Kuntz’s presentation.

The second nusinersen trial to be reported at the meeting will describe interim results of the drug’s efficacy and safety in children with later-onset SMA in the phase III CHERISH study. At the Emerging Science Platform Session on April 25, Richard S. Finkel, MD, of Nemours Children’s Hospital in Orlando, Fla., will discuss how the primary outcome of the Hammersmith Functional Motor Scale–Expanded score changed from baseline to 15 months following intrathecal injection or a sham procedure in children aged 2-12 years.

An investigational SMA type 1 treatment just beginning testing in clinical trials will also receive attention in a plenary session and a platform session. In the Clinical Trials Plenary Session on April 25, Jerry R. Mendell, MD, of Nationwide Children’s Hospital, Columbus, Ohio, will report on the first gene therapy trial for SMA type 1, a phase I trial of AVXS-101, which delivers the SMN gene in a AAV9 viral vector that is able to cross the blood-brain barrier. The primary objective of the trial is to assess safety of a single intravenous dose. The secondary objectives include survival (avoidance of death/permanent-ventilation) and the ability to sit unassisted. Other analyses of data from the phase I trial will be reported during the “Motor Neuron Diseases: Biomarkers, Outcome Measures, and Therapeutics,” platform session on April 24, including the evaluation of preexisting anti-AAV9 antibodies and the proportion of patients who achieve CHOP-INTEND scores of 50 and above and sit unassisted.

Lurie Children’s Hospital of Chicago will present the initial interim efficacy and safety findings from the phase III international ENDEAR study on April 24 at the Contemporary Clinical Issues Plenary Session. The study of 122 infants with SMA is comparing intrathecal administration of nusinersen against a sham procedure of a small needle prick on the lower back to look for differences at day 402 in the primary outcome of the percentage of patients who attain motor milestones as assessed by section 2 of the Hammersmith Infant Neurological Examination or the time to death or need for respiratory intervention. Charlotte J. Sumner, MD, of Johns Hopkins University, Baltimore, will discuss the study following Dr. Kuntz’s presentation.

The second nusinersen trial to be reported at the meeting will describe interim results of the drug’s efficacy and safety in children with later-onset SMA in the phase III CHERISH study. At the Emerging Science Platform Session on April 25, Richard S. Finkel, MD, of Nemours Children’s Hospital in Orlando, Fla., will discuss how the primary outcome of the Hammersmith Functional Motor Scale–Expanded score changed from baseline to 15 months following intrathecal injection or a sham procedure in children aged 2-12 years.

An investigational SMA type 1 treatment just beginning testing in clinical trials will also receive attention in a plenary session and a platform session. In the Clinical Trials Plenary Session on April 25, Jerry R. Mendell, MD, of Nationwide Children’s Hospital, Columbus, Ohio, will report on the first gene therapy trial for SMA type 1, a phase I trial of AVXS-101, which delivers the SMN gene in a AAV9 viral vector that is able to cross the blood-brain barrier. The primary objective of the trial is to assess safety of a single intravenous dose. The secondary objectives include survival (avoidance of death/permanent-ventilation) and the ability to sit unassisted. Other analyses of data from the phase I trial will be reported during the “Motor Neuron Diseases: Biomarkers, Outcome Measures, and Therapeutics,” platform session on April 24, including the evaluation of preexisting anti-AAV9 antibodies and the proportion of patients who achieve CHOP-INTEND scores of 50 and above and sit unassisted.

 

A variety of plenary and emerging science sessions at this year’s annual meeting of the American Academy of Neurology in Boston will highlight clinical research efforts to treat children with spinal muscular atrophy.

At the Hot Topics Plenary Session on April 22, Claudia A. Chiriboga, MD, of Columbia University, New York, will discuss the results of clinical trials involving antisense oligonucleotide treatments for spinal muscular atrophy (SMA), including the recently approved nusinersen (Spinraza), which promotes transcription of the full-length survival motor neuron (SMN) protein from the SMN2 gene.

Novel protein biomarker could accelerate ALS research

A protein found in the cerebrospinal fluid and peripheral blood cells of patients with a common type of amyotrophic lateral sclerosis may serve as a “pharmacodynamic marker,” providing a mechanism to assess RNA-based therapies that are now in clinical trials.

The protein, poly(GP), is expressed in patients who have a mutation in the gene chromosome 9 open reading frame 72 (C9ORF72), which causes one type of amyotrophic lateral sclerosis (ALS). This means that detecting poly(GP) also, eventually, may help to identify “presymptomatic individuals who are expected to benefit from early therapeutic interventions,” wrote the authors of a newly published paper (Sci Transl Med. 2017;9[383]:eaai7866).

Tania Gendron, PhD, of the department of neuroscience at the Mayo Clinic, Jacksonville, Fla., and her colleagues noted that poly(GP) was found in the cerebrospinal fluid (CSF) of both symptomatic and asymptomatic patients who carried the C9ORF72 mutation. The mutation can cause ALS, and is also associated with frontotemporal dementia (FTD) in a pattern with incomplete overlap with ALS.

T.F. Gendron et al., Science Translational Medicine (2017)
Motor neurons from mice that received an experimental ALS treatment (top) displayed lower levels of a newly identified biomarker (brown areas) than observed in untreated animals (bottom).
About 40% of patients with familial and 10% with sporadic ALS have the C9ORF72 mutation, which causes a short cytosine-guanine sequence to be repeated up to thousands of times. The RNA encoded by this repeat expansion, which also has the repeated sequence, has toxic effects that are now thought to be largely responsible for this type of ALS and FTD, termed c9ALS/FTD.

However, “A limitation in moving such treatments from bench to bedside is a lack of pharmacodynamics markers for use in clinical trials,” Dr. Gendron and her collaborators wrote. The discovery that poly(GP) tracks well with C9ORF72 means that it has the potential to serve as the kind of biomarker that’s been missing in drug development for this family of neurodegenerative diseases, they said.

“To prepare for upcoming clinical trials for c9ALS, the present study used patient CSF and several preclinical models to investigate the hypothesis that poly(GP) proteins could serve as an urgently needed pharmacodynamics marker for developing and testing therapies for treating c9ALS,” Dr. Gendron and her colleagues wrote.

They looked at CSF samples from 83 patients with c9ALS and 27 patients who were asymptomatic C9ORF72 repeat expansion carriers, as well as 24 carriers who had a neurologic disease besides ALS or FTD (total n = 134). They also examined CSF samples from 120 study participants who lacked the mutation, 48 of whom were healthy controls; the remainder had ALS (n = 57) or another neurological disease.

The investigators, who were blinded to individuals’ disease status in each study arm, found that CSF poly(GP) levels were significantly higher in patients who had the C9ORF72 mutation (P less than .0001 in unadjusted and adjusted analyses). Poly(GP) was present in both asymptomatic and symptomatic carriers of the mutation, and not significantly different between these groups when data were adjusted for multiple comparisons, age, and gender.

When Dr. Gendron and her colleagues looked at poly(GP) levels over time for patients whose longitudinal data were available, they found that levels for an individual study participant were “relatively constant,” without any significant change over the median 12.9 months that these levels were tracked (P = .84).

However, “poly(GP) is not a prognostic marker,” wrote Dr. Gendron and her colleagues. They found no consistent association between levels of the protein and disease severity of progression, age at onset, or the development of FTD. Women were more likely to have lower levels, but the significance of that finding is not known, they said. There was a trend, which lost significance after statistical adjustment, for patients with cognitive impairment to have higher poly(GP) levels (adjusted P = .12).

Treatments under investigation for ALS and FTD include the use of an antisense oligonucleotide (ASO) to bind to the repeated RNA sequences and negate their ill effects. The investigators wrote that in vitro investigations using patient-derived cell models showed that poly(GP) levels dropped when cells were exposed to an ASO for 10 days. “The data indicate that poly(GP) production mirrors expression of repeat-containing C9ORF72 transcripts in lymphoblastoid cell lines,” they wrote.

The authors reported multiple governmental and private foundation sources of support for the research. Dr. Gendron and several of her coauthors are investigators in clinical trials for an ASO to target C9ORF72. Several authors reported paid and unpaid relationships and stock positions with pharmaceutical companies, including ones developing treatments for ALS and FTD.

Outpatient Visits Involving CNS Polypharmacy Rising Among Elderly

Two-thirds of the polypharmacy visits were by women, and almost half included neither mental health nor pain diagnoses.

The number of outpatient visits involving CNS polypharmacy by adults aged 65 and older more than doubled between 2004 and 2013, especially among those who reside in rural areas, according to research published online ahead of print February 13 in JAMA Internal Medicine.

“With each new revision of the Beers Criteria, the list of psychotropic medications considered potentially inappropriate in the elderly has grown,” said Donovan T. Maust, MD, Assistant Professor of Geriatric Psychiatry at the University of Michigan in Ann Arbor. “Opioids have recently been included in a Beers measure of CNS polypharmacy. Prescribing related drug combinations also received increased regulatory attention when the US Food and Drug Administration recently ordered a black box warning to alert patients of serious risks, including death, caused by opioids coprescribed with CNS depressants,” he said.

Donovan T. Maust, MD

Dr. Maust and his colleagues analyzed data on 97,910 outpatients age 65 and older from the National Ambulatory Medical Care Survey (NAMCS) from 2004 through 2013. Patients met Beers CNS polypharmacy criteria if three or more of the following medications were initiated or continued: antipsychotics, benzodiazepines, nonbenzodiazepine benzodiazepine receptor agonists, tricyclic antidepressants, selective serotonin reuptake inhibitors, and opioids. The researchers recorded as many as three visit diagnoses and included information collected from NAMCS such as chronic medical conditions, whether psychotherapy was provided or ordered, whether stress management or other mental health counseling services were provided or ordered, and time spent with physician.

Dr. Maust and his associates found that annual CNS polypharmacy visits by adults age 65 or older increased from 1.50 million in 2004 to 3.68 million in 2013, or from 0.6% of visits in 2004 to 1.4% in 2013 (adjusted odds ratio [AOR], 3.12). The largest increases were observed among rural visits and among visits with no mental health or pain diagnoses (AOR, 4.99 and 2.65, respectively).

More than two-thirds of polypharmacy visits (68%) were by women, and 17% were by individuals who lived in rural areas. In addition, nearly half of polypharmacy visits studied (46%) included neither mental health nor pain diagnoses. No significant demographic differences were observed between polypharmacy visits with and without opioids. “Older adults have become more open to mental health treatment,” the researchers concluded. “Because of limited access to specialty care and a preference to receive treatment in primary care settings, it is unsurprising that mental health treatment has expanded in nonpsychiatric settings.”

LVADs achieve cardiac palliation in muscular dystrophies

LVAD can provide ‘reliable support’
Article Type

Tue, 02/14/2023 - 13:06

 

At one time, respiratory failure was the primary cause of death in young men and boys with muscular dystrophies, but since improvements in ventilator support have addressed this problem, cardiac complications such as cardiomyopathy have become the main cause of death in this group, with the highest risk of death in people with Duchenne muscular dystrophy (DMD). Researchers from Rome have reported that the novel use of ventricular assist devices in this population can prolong life.

Body

 

Almost all young men living with Duchenne muscular dystrophy will develop heart failure, but for many of these patients, continuous-flow left ventricular assist devices can provide “reliable support” for up to a decade, David L. S. Morales, MD, of the Heart Institute at Cincinnati Children’s Hospital Medical Center, said in his invited commentary (J Thorac Cardiovasc Surg. 2017;153:675-6)

“The current series demonstrates, as has been shown at our institute as well as others, that one can provide an effective therapy for certain patients with DMD and heart failure,” Dr. Morales said of the work of Dr. Perri and coauthors. Dr. Morales added that maximizing outcomes in this population hinges on finding the appropriate time point for intervention in the disease process.

While “there is still much to be learned,” Dr. Morales said, Dr. Perri and his coauthors have shown that LVAD therapy is an option in patients with DMD and heart failure who have failed other treatments. “These young men may, therefore, have the option to extend their lives and possibly have the opportunity to benefit from the impressive medical advances being made,” he said. “Perhaps they and their families have been provided hope.”

Dr. Morales disclosed relationships with Berlin Heart, HeartWare and Oregon Total Artificial Heart.

While “there is still much to be learned,” Dr. Morales said, Dr. Perri and his coauthors have shown that LVAD therapy is an option in patients with DMD and heart failure who have failed other treatments. “These young men may, therefore, have the option to extend their lives and possibly have the opportunity to benefit from the impressive medical advances being made,” he said. “Perhaps they and their families have been provided hope.”

Dr. Morales disclosed relationships with Berlin Heart, HeartWare and Oregon Total Artificial Heart.

At one time, respiratory failure was the primary cause of death in young men and boys with muscular dystrophies, but since improvements in ventilator support have addressed this problem, cardiac complications such as cardiomyopathy have become the main cause of death in this group, with the highest risk of death in people with Duchenne muscular dystrophy (DMD). Researchers from Rome have reported that the novel use of ventricular assist devices in this population can prolong life.

Key clinical point: A left ventricular assist device can be used as destination therapy in patients with Duchenne muscular dystrophy dystrophinopathies and end-stage dilated cardiomyopathy.

Major finding: Four of seven patients who had LVAD survived long term, and survival for the three who died ranged from 15 to 44 months.

Data source: Single-center, retrospective review of seven patients with DMD who had LVAD for DCM from February 2011 to February 2016.

Disclosure: Dr. Perri and his coauthors reported having no relevant financial disclosures.

FDA approves Emflaza for Duchenne muscular dystrophy

Emflaza, a tablet and oral suspension corticosteroid, has been approved by the Food and Drug Administration for the treatment of Duchenne muscular dystrophy in patients aged 5 years and older.

The agency’s Feb. 9 announcement notes that similar corticosteroids have been used around the world to treat Duchenne muscular dystrophy (DMD), but this is the first to gain approval in the United States. Emflaza (deflazacort) works by decreasing inflammation and immune system activity.

The drug received fast track status, priority review, and orphan drug designation from the FDA. It will be marketed in the United States by Marathon Pharmaceuticals.

DMD is the most common form of muscular dystrophy but is still rare, occurring in about 1 in 3,600 male infants worldwide. One study found that patients taking deflazacort had some improvements in muscle strength at 12 weeks, compared with those taking placebo, and maintained muscle strength stability through 52 weeks. A longer-term study showed that patients who took deflazacort had better average muscle strength than did those taking placebo and suggested that deflazacort helped prolong patients’ ability to walk.

Side effects experienced by patients taking Emflaza are similar to those associated with other corticosteroids, such as facial puffiness (cushingoid appearance), weight gain, increased appetite, upper respiratory tract infection, cough, extraordinary daytime urinary frequency (pollakiuria), unwanted hair growth (hirsutism), and excessive fat around the stomach (central obesity).

In the FDA’s announcement, Billy Dunn, MD, director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research, said, “We hope that this treatment option will benefit many patients with DMD.”
