Weight-loss drug options expand, but beware cardiac risk
LOS ANGELES – Newer medications are much more powerful, but they come with cautions – insurer coverage can be a hurdle, and there are significant gaps in knowledge about their risks for patients with heart disease, Ken Fujioka, MD, told colleagues at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.
Dr. Fujioka, of Scripps Clinic in San Diego, shared some tips with his peers about using medications to reduce weight.
Diabetes drugs help, but may need a boost
Metformin can reduce weight by as much as 3%, Dr. Fujioka said. And there may be another benefit related to long-term weight loss maintenance, he said, citing a 15-year study of overweight or obese patients at high risk for diabetes who either received metformin, underwent an intensive lifestyle intervention, or took a placebo. Of the participants with weight loss of at least 5% after the first year, those originally assigned to receive metformin had the greatest weight loss during years 6-15. Older age, the amount of weight initially lost, and continued used of metformin were predictors of long-term weight loss maintenance, according to the researchers (Ann Intern Med. 2019 Apr 23. doi: 10.7326/M18-1605).
There are other options among diabetes drugs. Sodium-glucose cotransporter 2 (SGLT2) inhibitors – a class of drugs that includes canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance) – have a striking effect on weight loss, Dr. Fujioka said. They can cause 300 calories to be flushed out in the urine each day. But that typically doesn’t translate into weight loss of more than 20 pounds, he said, because the body doesn’t fully adjust to fewer calories.
“The patients begin to eat more,” he said. “They have to take in more calories to make up for [the loss]. They’re not consciously trying to do this. It’s a metabolic adaptation, so 2%-3% [weight loss] is about all you’ll get. You won’t get 10% or 20%.”
To drive up weight loss, Dr. Fujioka recommended adding the glucagonlike peptide–1 [GLP1] receptor diabetes drug exenatide (Byetta; Bydureon) or the appetite suppressant phentermine (Adipex-p; Lomaira) to an SGLT2 inhibitor. Recent studies have shown that the drug combinations have a greater impact on weight loss than when taken separately (Lancet Diabetes Endocrinol. 2016 Dec;4[12]:1004-16; Diabetes Care. 2017 May;40[5]:632-9).
In regard to phentermine, which acts similarly to amphetamine, Dr. Fujioka advised colleagues to be aware that “15 mg or less is really safe, but you drive pulse and heart rate beyond that.”
Consider insurance coverage and other factors
Often, insurers will pay for GLP1-receptor and SGLT2-inhibitor medications in patients with diabetes, even if their hemoglobin A1c is in the healthy range, Dr. Fujioka said, but they’ll balk at paying for specific weight-loss medications, although that can vary by the region of the country. He added that cash discount cards are available for several weight-loss drugs.
Newer weight-loss drugs ...
Dr. Fujioka highlighted a quartet of weight-loss drugs that have been approved in recent years.
- Lorcaserin (Belviq), a selective serotonin 2C receptor agonist, has shown unique benefits in patients with diabetes. A large, multinational, randomized controlled trial found that the drug reduced the risk for incident diabetes, induced remission of hyperglycemia, and reduced the risk of microvascular complications in obese and overweight patients (Lancet. 2018 Nov 24;392[10161]:2269-79).
- Phentermine/topiramate (Qsymia), a combination of an antiseizure medication (topiramate) and an appetite suppressant (phentermine). A 2014 study found that the drug, together with lifestyle modification, effectively promoted weight loss and improved glycemic control in obese or overweight patients with type 2 diabetes (Diabetes Care. 2014 Dec;37[12]:3309-16).
- Naltrexone/bupropion (Contrave), a combination of an addiction drug (naltrexone) and an antidepressant (bupropion). Findings from a 2013 study reported that the drug “in overweight/obese patients with type 2 diabetes induced weight loss... was associated with improvements in glycemic control and select cardiovascular risk factors and was generally well tolerated with a safety profile similar to that in patients without diabetes.” (Diabetes Care. 2013 Dec;36[12]:4022-9).
- Liraglutide, an injectable GLP1 agonist that has been approved for diabetes (Victoza) and weight loss (Saxenda). Dr. Fujioka was coauthor for a study in which the findings suggested that the drug could prevent prediabetes from turning into diabetes. (Lancet. 2017 Apr 8;389[10077]:1399-409).
... but watch out for safety in patients with heart disease
Two of the newer weight-loss drugs are OK to prescribe for diabetic patients with heart disease, Dr. Fujioka said, but two are not, because no cardiac safety trials have been completed for them.
Liraglutide (at a dose of 3.0 mg) is considered safe based on previous data (Diabetes Obes Metab. 2018 Mar;20[3]:734-9), Dr. Fujioka said. Likewise, findings from a trial with lorcaserin in which 12,000 overweight or obese patients with atherosclerotic cardiovascular disease or multiple cardiovascular risk factors received either lorcaserin (10 mg twice daily) or placebo, suggested that lorcaserin helped sustain weight loss without a higher rate of major cardiovascular events compared with placebo (N Engl J Med. 2018 Sep 20;379[12]:1107-17).However, no such cardiac safety trials have been completed for naltrexone/bupropion or phentermine/topiramate, said Dr. Fujioka. As a result, he said he could not recommend either of them for patients with high-risk cardiovascular disease.
Dr. Fujioka disclosed relationships of various types with Novo Nordisk, Eisai, Gelesis, KVK Tech, Amgen, Sunovion, Boehringer Ingelheim, and Janssen Global Services.

EXPERT ANALYSIS FROM AACE 2019
Gabapentin falls short in treating sickle cell pain
NEW ORLEANS – Adding gabapentin to standard therapy did not significantly reduce vaso-occlusive pain in most patients with sickle cell disease enrolled in a phase 2 trial.
In the entire cohort, there were no significant differences in pain response between patients who received gabapentin and those who received placebo. However, patients with the HbSS genotype had a significantly greater decrease in pain score from baseline to discharge if they received gabapentin rather than placebo.
Additional studies are needed to confirm these findings because this trial was limited by a small sample size, according to study investigator Latika Puri, MD, of St. Jude Children’s Research Hospital in Memphis. Dr. Puri presented the trial at the annual meeting of the American Society of Pediatric Hematology/Oncology.
The trial included 86 evaluable patients who had vaso-occlusive pain and a pain score of at least 4. All patients received standard therapy for vaso-occlusive pain and were randomized to receive placebo (n = 44) or a single oral dose of gabapentin at 15 mg/kg (n = 42).
Baseline characteristics were similar between the treatment arms. For the entire cohort, the mean age was 11.8 years (range, 1-21 years), and 51% of patients were male. Forty-four patients had the HbSS genotype, 25 had the HbSC genotype, 8 had HbS/beta0-thalassemia, and 9 had other genotypes.
The mean pain score at baseline was 7.8 for the entire cohort, 8.0 for the gabapentin arm, and 7.7 for the placebo arm.
For the entire cohort, there was no significant difference in pain response between the gabapentin and placebo arms.
The proportion of patients who experienced a greater than 33% decrease in pain from baseline to 3 hours posttreatment was 67% in the gabapentin arm and 59% in the placebo arm (P = .23). The proportion of patients who experienced a greater than 33% decrease from baseline to discharge from the acute care clinic was 75% and 61%, respectively (P = .18).
In the entire cohort, decreases in pain scores from baseline to 3 hours posttreatment were not significantly different between the gabapentin and placebo arms, at 1.3 and 0.7, respectively (P = .74). Likewise, decreases in pain scores from baseline to discharge were not significantly different, at 1.6 and 0.8 (P = .38).
Among patients who had the HbSS genotype, there was a significantly greater decrease in pain score from baseline to discharge in the gabapentin arm than in the placebo arm, 5.9 versus 3.6 (P = .03). However, there were no other significant differences in pain response for the HbSS subgroup.
There were no significant differences in opioid consumption or hospitalization for the HbSS subgroup or the entire cohort. For the entire cohort, the mean morphine equivalent dose from baseline to 3 hours posttreatment was 0.16 mg/kg in the gabapentin arm and 0.17 mg/kg in the placebo arm (P = .89). For the HbSS subgroup, the mean dose was 0.16 mg/kg and 0.15 mg/kg, respectively (P = .93).
In the entire cohort, 24% of patients in the gabapentin arm and 27% of those in the placebo arm were hospitalized (P = .71). In the HbSS subgroup, hospitalizations occurred in 11% and 35% (P = .15).
Dr. Puri pointed out several challenges that led to limitations in this study. Specifically, the investigators had to obtain patient consent while delivering standard treatment, while patients were in pain and distress, and from patients who had already received opioids and were sleepy. Additionally, gabapentin had to be delivered within 1 hour of opioid administration, and a lack of after-hours staff limited enrollment.
“These challenges led to one of our biggest limitations, which was a small sample size, leading to a limited power to observe real differences,” Dr. Puri said. “We also defined a very short time period of evaluation for the primary outcomes; that was 3 hours from the gabapentin dose or placebo dose. This limited our capability to see real differences if they existed.”
Dr. Puri said additional studies with larger sample sizes are needed to confirm these findings. She added that efforts to better characterize pain in sickle cell disease could reveal patients who may benefit from gabapentin because they have a neuropathic component to their pain.
The trial was sponsored by St. Jude Children’s Research Hospital in collaboration with Scan|Design Foundation. Dr. Puri did not provide disclosure information at the meeting.

Painful, slow-growing recurrent nodules
A 67-year-old woman presented with multiple painful nodules that had developed on her scalp, face, and neck over the course of 1 year. She also had a few nodules on her trunk and hip. There was no associated bleeding, ulceration, or drainage from the lesions. She had no systemic symptoms. The patient reported that she’d had a similar lesion on her frontal scalp about 15 years earlier, and it was excised completely. (She was not aware of the diagnosis.) She indicated that her mother and son had similar lesions in the past.
Her medical history was remarkable for diabetes and hypertension, which were well controlled on metformin and lisinopril, respectively. The patient had cancer of the left breast that was treated with mastectomy and chemotherapy 3 years prior.
On physical examination, the patient had multiple firm, rubbery, tender nodules with tan or pink hue, measuring 1 to 1.5 cm. The nodules were located on the left side of her chin and right preauricular area (FIGURE 1), as well as the right sides of her neck and hip. Most of the nodules were solitary; the preauricular area had 2 clustered pink lesions. The largest nodule was located on the patient’s chin and had overlying telangiectasias.
WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?
Diagnosis: Cylindroma
Definitive diagnosis was made by shave biopsy of the left hip lesion. Histopathology demonstrated various-sized discrete aggregates of basaloid cell nests in a jigsaw puzzle–like configuration (FIGURE 2), surrounded by rims of homogenous eosinophilic material. Histologic findings were consistent with cylindroma.1
Rare with a female predominance. Solitary cylindromas occur sporadically and usually affect middle-aged and elderly patients. Incidence is rare, but there is a female predominance of 6 to 9:1.2 Clinical appearance shows a slow-growing, firm mass that can range from a few millimeters to a few centimeters in diameter. The masses can have a pink or blue hue and usually are nontender unless there is nerve impingement.2
If multiple tumors are present or the patient has a family history of similar lesions, the disorder is likely inherited in an autosomal dominant pattern (with variable expression), which can be associated with Brooke-Spiegler syndrome. This syndrome is related to a mutation of the cylindromatosis gene on chromosome 16. This is a tumor suppressor gene, inactivation of which can lead to uninhibited action of NF-
Rarely, cylindromas can undergo malignant transformation; signs include ulceration, bleeding, rapid growth, or color change.2 In these cases, appropriate imaging such as computed tomography, magnetic resonance imaging, or positron emission tomography should be sought as there have been case reports of cylindroma extension to bone, as well as metastases to sites including the lymph nodes, thyroid, liver, lungs, bones, and meninges.4
Lipomas and pilar cysts comprise the differential
Lipomas are soft, painless, flesh-colored masses that typically appear on the trunk and arms but are uncommon on the face. Telangiectasias are not seen.
Continue to: Pilar cysts
Pilar cysts can mimic cylindromas in clinical presentation. Derived from the root sheath of hair follicles, they typically appear on the scalp but rarely on the face. Pilar cysts are slow growing, firm, and whitish in color5; several cysts can appear at a time.
Pilomatricomas are firm skin masses—usually < 3 cm in size—that can vary in color. There may be an extrusion of calcified material within the nodules, which does not occur in cylindromas.
Sebaceous adenomas are yellowish papules, usually < 1 cm in size, that appear on the head and neck area.6
Making the diagnosis. The clinical appearance of cylindromas and their location will point to the diagnosis, as will a family history of similar lesions. Ultimately, the diagnosis is confirmed by biopsy.
Treatment mainstay includes excision
Complete excision of all lesions is key due to the possibility of malignant transformation and metastasis. Options for removal include electrodesiccation, curettage, cryosurgery,3 high-dose radiation, and the use of a CO2 laser.2 For multiple large tumors, or ones in cosmetically sensitive areas, consider referral to Dermatology or Plastic Surgery. Further imaging should be sought to rule out extension to bone or metastasis. Patients with multiple cylindromas and Brooke-Spiegler syndrome need lifelong follow-up to monitor for recurrence and malignant transformation.3,7,8

Our patient underwent complete excision of the left hip lesion. Other trunk lesions were excised serially. The patient was referred to a surgeon specializing in Mohs micrographic surgery for excision of the facial lesions. The patient and her family members were referred for genetic testing.

Single-center study outlines stroke risk, DOAC type in nonvalvular AFib patients
PHILADELPHIA – A disproportionate number of breakthrough strokes were observed among patients receiving rivaroxaban for nonvalvular atrial fibrillation in a stroke unit, according to a small, single-center, retrospective study presented at the annual meeting of the American Academy of Neurology.
The researchers reviewed all patients presenting to a tertiary care stroke unit in Australia from January 2015 to June 2018.
A total of 56 patients (median age was 74 years; 61% were male) had received direct oral anticoagulant (DOAC) therapy and then had an ischemic stroke. Of those patients, 37 (66%) had strokes while receiving the treatment; 14 patients (25%) had a stroke after recently stopping a DOAC, often prior to a medical procedure; and 5 patients (9%) were not adherent to their DOAC regimen.
Of the 37 patients who had strokes during DOAC treatment, 48% were on rivaroxaban, 9% were on dabigatran, and 9% were on apixaban, Fiona Chan, MD, of The Princess Alexandra Hospital, Brisbane, Australia, and coinvestigators reported in a poster presentation.
While these findings need to be replicated in a larger study, they do “raise concern for inadequate stroke prevention within this cohort,” they said.
Moreover, the findings illustrate the importance of bridging anticoagulation prior to procedures, when appropriate, to minimize stroke risk, they added, as 25% of the strokes had occurred in patients who recently stopped the DOACs due to procedures.
To determine which DOAC was most often associated with breakthrough ischemic strokes in patients with nonvalvular atrial fibrillation, the investigators compared the proportion of DOACs prescribed in Australia to the proportion of observed strokes in their cohort.
Despite accounting for about 51% of Australian DOAC prescriptions, rivaroxaban represented nearly 73% of breakthrough strokes among the patients who had strokes while receiving the treatment (P = .001), the investigators reported.
Conversely, apixaban accounted for about 35% of prescriptions but 14% of the breakthrough strokes (P = .0007), while dabigatran accounted for 14% of prescriptions and 14% of the strokes (P = 0.99), the investigators said in their poster.
One limitation of this retrospective study is that the patient cohort came from a single specialized center, and may not reflect the true incidence of nonvalvular atrial fibrillation across Australia, the researchers noted.
Dr. Chan and coinvestigators reported that they had no relevant financial disclosures.

Immunotherapy induces improvements in PML
Philadelphia – Adoptive transfer of donor-derived T cells represents a potentially life-saving treatment of severely immunocompromised patients with progressive multifocal leukoencephalopathy (PML).
“We think this strategy has real potential to be one of the first effective treatments for PML,” Erin Beck, MD, PhD, said during a press conference at the annual meeting of the American Academy of Neurology.
In a pilot study including 12 patients with PML, the 7 who survived had substantial neurological improvement after treatment with this immunotherapeutic approach, said Dr. Beck of the National Institute of Neurological Disorders and Stroke.
“This was very encouraging to us because these patients were worsening at the time of their treatment and we did not expect them to do well,” she said.
There were no serious adverse events related to treatment, which suggests the approach is safe for patients with PML, according to Dr. Beck.
“This is a phenomenal breakthrough,” Natalia S. Rost, MD, MPH, chair of the meeting’s science committee, said at the press conference. “Giving a diagnosis of PML to a patient is basically giving them a death sentence, and it’s one of the most dreaded scenarios in our clinical practice.”
PML, an opportunistic infection of the central nervous system caused by JC polyomavirus, is usually fatal unless adaptive immunity to JC polyomavirus can be restored, Dr. Beck said.
Cases of PML surged in the 1980s and 1990s as a result of the HIV/AIDS epidemic, she said, and an increase in cases has been observed more recently related to new immunosuppressive treatments for cancer and autoimmune diseases.
The pilot study described by Dr. Beck included 12 patients with refractory PML who underwent adoptive transfer of polyomavirus-specific T cells (PyVSTs) that were generated from partially matched first-degree relatives of the patients. Up to three infusions were given at least 28 days apart.
Although five patients died of PML, the remaining seven patients stabilized and in some cases experienced significant neurological improvement, according to the investigators. Two of the seven died of PML a year after their final infusion.
No overt immune reconstitution inflammatory syndrome (IRIS) was observed in treated patients.
It’s not clear to date which PML patients may be most likely to benefit from this treatment approach because there were no differences in age, sex, baseline leukocyte count numbers, or time since their initial diagnosis between responders and nonresponders, Dr. Beck said.
However, patients who died tended to have much higher JC virus copy numbers in their spinal fluid, as did some patients who were enrolled but died before they could receive any treatment, she added.
“That high range, I think, is a very bad prognostic sign,” Dr. Beck said. “A number in the lower range doesn’t mean a good prognosis, but it means potentially that you could respond to a treatment such as this one.”

Philadelphia – Adoptive transfer of donor-derived T cells represents a potentially life-saving treatment of severely immunocompromised patients with progressive multifocal leukoencephalopathy (PML).
“We think this strategy has real potential to be one of the first effective treatments for PML,” Erin Beck, MD, PhD, said during a press conference at the annual meeting of the American Academy of Neurology.
In a pilot study including 12 patients with PML, the 7 who survived had substantial neurological improvement after treatment with this immunotherapeutic approach, said Dr. Beck of the National Institute of Neurological Disorders and Stroke.
“This was very encouraging to us because these patients were worsening at the time of their treatment and we did not expect them to do well,” she said.
There were no serious adverse events related to treatment, which suggests the approach is safe for patients with PML, according to Dr. Beck.
“This is a phenomenal breakthrough,” Natalia S. Rost, MD, MPH, chair of the meeting’s science committee, said at the press conference. “Giving a diagnosis of PML to a patient is basically giving them a death sentence, and it’s one of the most dreaded scenarios in our clinical practice.”
PML, an opportunistic infection of the central nervous system caused by JC polyomavirus, is usually fatal unless adaptive immunity to JC polyomavirus can be restored, Dr. Beck said.
Cases of PML surged in the 1980s and 1990s as a result of the HIV/AIDS epidemic, she said, and an increase in cases has been observed more recently related to new immunosuppressive treatments for cancer and autoimmune diseases.
The pilot study described by Dr. Beck included 12 patients with refractory PML who underwent adoptive transfer of polyomavirus-specific T cells (PyVSTs) that were generated from partially matched first-degree relatives of the patients. Up to three infusions were given at least 28 days apart.
Although five patients died of PML, the remaining seven patients stabilized and in some cases experienced significant neurological improvement, according to the investigators. Two of the seven died of PML a year after their final infusion.
No overt immune reconstitution inflammatory syndrome (IRIS) was observed in treated patients.
It’s not clear to date which PML patients may be most likely to benefit from this treatment approach because there were no differences in age, sex, baseline leukocyte count numbers, or time since their initial diagnosis between responders and nonresponders, Dr. Beck said.
However, patients who died tended to have much higher JC virus copy numbers in their spinal fluid, as did some patients who were enrolled but died before they could receive any treatment, she added.
“That high range, I think, is a very bad prognostic sign,” Dr. Beck said. “A number in the lower range doesn’t mean a good prognosis, but it means potentially that you could respond to a treatment such as this one.”

United States up to 764 measles cases for the year
The number of U.S. measles cases in 2019 rose by 60 during the week ending May 3, which puts the new postelimination high at 764 cases for the year, according to the Centers for Disease Control and Prevention.
The CDC is currently tracking nine measles outbreaks in six states. The largest outbreak this year has been in New York City, mainly Brooklyn, which has almost half (367) of all cases in the country. An outbreak in New York’s Rockland County has resulted in another 109 cases so far this year. California is experiencing outbreaks in three counties – Butte, Los Angeles, and Sacramento – and the state was up to 40 confirmed cases as of May 1. The other states with outbreaks are Michigan, New Jersey, Georgia, and Maryland.
Twenty-three states now have reported measles cases in 2019, as officials in Pittsburgh reported Pennsylvania’s first case on April 30. Four additional cases in the area were reported on May 2 by the Allegheny County Health Department. A measles outbreak is “defined as three or more cases” by the CDC, but the situation in Pennsylvania is not yet being reported as such.
One Pennsylvania legislator in the state, Rep. Daryl Metcalfe (R) of Butler County, has authored a bill that would “bar health care practitioners and facilities and insurance companies from denying care if parents refuse or delay” recommended vaccinations, PennLive.com reported.
Pennsylvania Governor Tom Wolf (D) said that the “bill would put children, pregnant women, and vulnerable patients at risk of being exposed to horrific diseases – at the doctor’s office.”

ARCHES: Enzalutamide improves mHSPC survival regardless of baseline PSA
For men with metastatic hormone-sensitive prostate cancer (mHSPC), enzalutamide with androgen deprivation therapy (ADT) offers longer radiographic progression-free survival (rPFS) compared with placebo and ADT, regardless of baseline prostate-specific antigen level (PSA), based on results from the phase 3 ARCHES trial.
Although initial PSA level was not predictive of response, treatment with enzalutamide and ADT improved PSA-related efficacy measures, reported lead author Arnulf Stenzl, MD, of the University of Tübingen, Germany, and colleagues. The adverse effect profile of enzalutamide was similar to previous experiences with castrate-resistant patients, they noted in their abstract, which was presented at the annual meeting of the American Urological Association.
ARCHES was a double-blind, placebo-controlled trial involving 1,150 patients with mHSPC, divided approximately 1:1 to receive either enzalutamide with ADT (n = 574) or placebo with ADT (n = 576). Eligibility required that patients had not exhibited radiographic disease progression or rising PSA levels for up to 3 months of ADT, or up to 6 months with prior docetaxel. The primary endpoints were death within 24 weeks of stopping treatment and rPFS. Treatment was continued until unacceptable toxicity or disease progression. PSA levels were measured at baseline and at follow-up, which was an average of 14.4 months.
Median baseline PSA level across both cohorts was 5.21 ng/mL, with most patients having received prior ADT (91%). Baseline PSA was not predictive of response, “suggesting the limitation of baseline PSA as a predictive factor in this population in which most [patients] received prior ADT,” the investigators wrote. Although PSA levels were not predictive, enzalutamide did have a greater impact on PSA-related efficacy endpoints; compared with the placebo group, patients in the enzalutamide arm were significantly more likely to have PSA reductions from baseline of at least 50% (92.9% vs. 56.8%) and at least 90% (72.8% vs. 30.0%). In further support of the efficacy of enzalutamide, median rPFS in the enzalutamide group was significantly better than in the placebo group (not reached vs. 19.4 months). Adverse events were comparable between enzalutamide (85.1%) and placebo (85.9%) cohorts.
Astellas Pharma and Medivation funded the study. The investigators reported no conflicts of interest.

Angelman syndrome treatment safe, well-tolerated, and effective in exploratory analyses
Philadelphia – according to results of a study presented at the annual meeting of the American Academy of Neurology.
Clinician-rated clinical global impressions of improvement (CGI-I) were improved versus placebo in the randomized study, as were other outcomes in post hoc analyses, including measures of sleep and motor function, said Alexander Kolevzon, MD, professor of psychiatry and pediatrics at the Icahn School of Medicine at Mount Sinai, New York.
This study of OV101 was a genetics-driven trial for the rare genetic disorder, which is caused by mutations in UBE3A and characterized by seizures, speech impairments, profound intellectual disability, gait problems, and anxiety, Dr. Kolevzon said in a press conference.
“The only treatments that exist are really very symptomatically driven,” Dr. Kolevzon said. “Here, we are taking a genetics-first approach. Having identified the gene, there is some understanding of what the underlying biology is, and it seems to relate to deficits in tonic inhibition.”
OV101 is a delta-selective type A gamma-aminobutyric acid receptor agonist that may potentially normalize the tonic inhibition that is decreased in Angelman syndrome. “What we think this compound is doing is actually reversing the deficits of tonic inhibition, and sort of restoring that state to these patients,” Dr. Kolevzon said in the press conference.
A total of 78 patients completed the phase 2, randomized study, known as STARS, which had a primary endpoint of safety and tolerability over 12 weeks of treatment with OV101 once daily, twice daily, or placebo. The mean age of the 87 patients who enrolled and had at least one dose of study drug was 22.6 years.
Most adverse events were mild, and frequencies of specific adverse events were similar for OV101 and placebo treatment groups, according to Dr. Kolevzon and his coinvestigators.
Improvements in motor function, sleep, and behavior were seen in a series of exploratory analyses, including global improvement at week 12, as captured by CGI-I, which was significantly improved for daily OV101 versus placebo (P = .0006).
These phase 2 results have informed discussions of which specific endpoints might be incorporated into the design of a planned phase 3 trial in pediatric patients. The CGI-I may be especially useful to measure clinical improvement in Angelman syndrome, which is a very “heterogeneous” disorder, Dr. Kolevzon said in the press conference.
“Every child has a different composite of symptoms, so that is the big challenge,” Dr. Kolevzon said. “I do not think we are going to have one singular outcome. The idea is to have a global measure that really captures heterogeneity across each trial and allows for children to be compared to their baseline, and each as their own control, in essence, but with specific domains in mind.”
Funding for the study came from Ovid Therapeutics. Dr. Kolevzon reported disclosures related to Ovid Therapeutics, as well as Coronis Neurosciences, 5AM Ventures, SEMA4, LabCorp, and AMO Pharma.

Biomarkers in tears may help identify patients with Parkinson’s disease
PHILADELPHIA – according to research presented at the annual meeting of the American Academy of Neurology. Chemokine (C-C motif) ligand 2 (CCL2), a cytokine, may be used for the same purpose, according to researchers.
Lacrimal glands have high numbers of cholinergic and other neurons. Parasympathetic and sympathetic neural pathways stimulate the tears that lacrimal grands secrete. It is possible that the production, packaging, and secretion of proteins into tears may alter when nerve function in the lacrimal glands and cornea changes. This idea may be tested by collecting reflex tears (i.e., stimulated tears provoked by an unanesthetized Schirmer’s test).
Mark Lew, MD, professor of clinical neurology at University of Southern California, Los Angeles, and colleagues previously studied patients using basal tears collected from an anesthetized Schirmer’s test. To examine whether the protein composition of reflex tears differs in patients with Parkinson’s disease, compared with healthy controls, they collected reflex tears from 85 patients with Parkinson’s disease and 80 age- and sex-matched healthy controls using an unanesthetized Schirmer’s test. The researchers pooled samples from both eyes to analyze alpha synuclein, CCL2, and total protein using enzyme-linked immunosorbent assays or multiplex ELISA.
Eligible participants were aged 30-85 years and had a Montreal Cognitive Assessment (MoCA) score of 21 or higher. Patients with Parkinson’s disease had a lower MoCA score than controls did, although it was still in the normal range. Tear flow was significantly decreased in patients with Parkinson’s disease, compared with controls.
Dr. Lew and colleagues found that the amount of oligomeric alpha synuclein was increased nearly 400% in the tears of patients with Parkinson’s disease, compared with those of healthy controls (4.21 ng/mg tear protein vs. 0.90 ng/mg tear protein). This difference was statistically significant. Similarly, CCL2 was significantly increased in the tears of patients with Parkinson’s disease, compared with those of healthy controls (165.8 pg/mg tear protein vs. 116.3 pg/mg tear protein). Among men, Parkinson’s disease was associated with greater rises in oligomeric alpha synuclein (4.95 ng/mg tear protein vs. 0.89 ng/mg tear protein in healthy controls) and CCL2 (201.5 pg/mg tear protein vs. 117.9 pg/mg tear protein in healthy controls) than in women. The origin of sex differences in these biomarker values requires further study, the investigators said.
Dr. Lew reported receiving research support from the Parkinson’s Study Group, the Michael J. Fox Foundation, Biotie Therapies, NeuroDerm, Enterin, Pharm2B Fellowship Grants, Allergan, and Medtronic.

This idea may be tested by collecting reflex tears (i.e., stimulated tears provoked by an unanesthetized Schirmer’s test).
Mark Lew, MD, professor of clinical neurology at University of Southern California, Los Angeles, and colleagues previously studied patients using basal tears collected from an anesthetized Schirmer’s test. To examine whether the protein composition of reflex tears differs in patients with Parkinson’s disease, compared with healthy controls, they collected reflex tears from 85 patients with Parkinson’s disease and 80 age- and sex-matched healthy controls using an unanesthetized Schirmer’s test. The researchers pooled samples from both eyes to analyze alpha synuclein, CCL2, and total protein using enzyme-linked immunosorbent assays or multiplex ELISA.
Eligible participants were aged 30-85 years and had a Montreal Cognitive Assessment (MoCA) score of 21 or higher. Patients with Parkinson’s disease had a lower MoCA score than controls did, although it was still in the normal range. Tear flow was significantly decreased in patients with Parkinson’s disease, compared with controls.
Dr. Lew and colleagues found that the amount of oligomeric alpha synuclein was increased nearly 400% in the tears of patients with Parkinson’s disease, compared with those of healthy controls (4.21 ng/mg tear protein vs. 0.90 ng/mg tear protein). This difference was statistically significant. Similarly, CCL2 was significantly increased in the tears of patients with Parkinson’s disease, compared with those of healthy controls (165.8 pg/mg tear protein vs. 116.3 pg/mg tear protein). Among men, Parkinson’s disease was associated with greater rises in oligomeric alpha synuclein (4.95 ng/mg tear protein vs. 0.89 ng/mg tear protein in healthy controls) and CCL2 (201.5 pg/mg tear protein vs. 117.9 pg/mg tear protein in healthy controls) than in women. The origin of sex differences in these biomarker values requires further study, the investigators said.
Dr. Lew reported receiving research support from the Parkinson’s Study Group, the Michael J. Fox Foundation, Biotie Therapies, NeuroDerm, Enterin, Pharm2B Fellowship Grants, Allergan, and Medtronic.
