Small-molecule CGRP receptor antagonists may pose a risk during stroke
“It turns out that these drugs make the blood vessels of the brain dysfunctional, such that the collateral channels that bring in blood to the region that is having the stroke are impaired,” explains the study’s lead author, Cenk Ayata, MD, associate professor of neurology and radiology at Harvard Medical School, Boston.
In an interview, Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, talks with Dr. Ayata about his study findings, and about CGRP receptor antagonists’ potential effects if a patient has an ischemic event.

Actor Alan Alda discusses using empathy as an antidote to burnout
LA JOLLA, CALIF. – Physicians and other medical professionals who routinely foster empathic connections with patients may be helping themselves steer clear of burnout.
That’s what iconic actor Alan Alda suggested during a media briefing at Scripps Research on Jan. 16, 2020.
“There’s a tremendous pressure on doctors now to have shorter and shorter visits with their patients,” said the 83-year-old Mr. Alda, who received the Public Welfare Medal from the National Academy of Sciences in 2016 for his work as a champion of science. “A lot of that time is taken up with recording on a computer, which can only put pressure on the doctor.”
Practicing empathy, he continued, “kind of opens people up to one another, which inspirits them.”
Mr. Alda appeared on the research campus to announce that Scripps Research will serve as the new West Coast home of Alda Communication Training, which will work in tandem with the Alan Alda Center for Communicating Science at Stony Brook (N.Y.) University, a nonprofit organization that Mr. Alda helped found in 2009.
“This will be a center where people can come to get training in effective communication,” Mr. Alda, who is the winner of six Emmy Awards and six Golden Globe awards, told an audience of scientists and medical professionals prior to the media briefing.
“It’s an experiential kind of training,” he explained. “We don’t give tips. We don’t give lectures. We put you through exercises that are fun and actually make you laugh, but turn you into a better communicator, so you’re better able to connect to the people you’re talking to.”
During a question-and-answer session, Mr. Alda opened up about his Parkinson’s disease, which he said was diagnosed about 5 years ago. In 2018, he decided to speak publicly about his diagnosis for the first time.
“The reason was that I wanted to communicate to people who had recently been diagnosed not to believe or give into the stereotype that, when you get a diagnosis, your life is over,” said Mr. Alda, who played army surgeon “Hawkeye” Pierce on the TV series “M*A*S*H.”
“Under the burden of that belief, some people won’t tell their family or workplace colleagues,” he said. “There are exercises you can do and medications you can take to prolong the time it takes before Parkinson’s gets much more serious. It’s not to diminish the fact that it can get really bad; but to think that your life is over as soon as you get a diagnosis is wrong.”
The first 2-day training session at Scripps Research will be held in June 2020. Additional sessions are scheduled to take place in October and December. Registration is available at aldacommunicationtraining.com/workshops.

Experts break down latest CAR T-cell advances in lymphoma
ORLANDO – There’s now mature data surrounding the use of chimeric antigen receptor (CAR) T-cell therapy in lymphoma, and the annual meeting of the American Society of Hematology brought forth additional information from real-world studies, insights about what is driving relapse, and promising data on mantle cell lymphoma.
The roundtable participants included Brian Hill, MD, of the Cleveland Clinic Taussig Cancer Center; Frederick L. Locke, MD, of the Moffit Cancer Center in Tampa, Fla.; and Peter Riedell, MD, of the University of Chicago.
Among the studies highlighted by the panel was the Transcend NHL 001 study (Abstract 241), which looked at third-line use of lisocabtagene maraleucel (liso-cel) in patients with diffuse large B-cell lymphoma, transformed follicular lymphoma, and other indolent non-Hodgkin lymphoma subtypes. More than 300 patients were enrolled, and liso-cel met all primary and secondary efficacy endpoints, with an overall response rate of more than 70%. The notable take-home point from the study was the safety profile, Dr. Riedell noted. Liso-cel was associated with a lower rate of cytokine release syndrome and neurologic toxicity, compared with the currently approved products.
Since patients in the study had a lower incidence and later onset of cytokine release syndrome, liso-cel could be a candidate for outpatient administration, Dr. Locke said. However, doing that would require “significant infrastructure” in hospitals and clinics to properly support patients, especially given that the treatment-related mortality on the study was similar to approved CAR T-cell products at about 3%. “You have to be ready to admit the patient to the hospital very rapidly, and you have to have the providers and the nurses who are vigilant when the patient is not in the hospital,” he said.
Another notable study presented at ASH examined the characteristics and outcomes of patients receiving bridging therapy while awaiting treatment with axicabtagene ciloleucel (Abstract 245). This real-world study adds interesting information to the field because, in some of the studies that were pivotal to the approval of CAR T-cell therapy, bridging therapy was not allowed, Dr. Locke said.
In this analysis, researchers found that the overall survival was worse among patients who received bridging. This finding suggests that patients who received bridging therapy had a different biology or that the therapy itself may have had an effect on the host or tumor microenvironment that affected the efficacy of the CAR T-cell therapy, the researchers reported.
The panel also highlighted the Zuma-2 study, which looked at KTE-X19, an anti-CD19 CAR T-cell therapy, among more than 70 patients with relapsed/refractory mantle cell lymphoma who had failed treatment with a Bruton’s tyrosine kinase inhibitor (Abstract 754). “This was, I thought, kind of a sleeper study at ASH,” said Dr. Hill, who was one of the authors of the study.
The overall response rate was 93% with about two-thirds of patients achieving a complete response. Researchers found that the response was consistent across subgroups, including Ki-67 and patients with prior use of steroids or bridging therapy. Dr. Locke, who was also a study author, said the results are a “game changer.”
“I’m very excited about it,” Dr. Riedell said, noting that these are patients without a lot of treatment options.
The panel also discussed other studies from ASH, including an analysis of tumor tissue samples from patients in the ZUMA-1 trial who had responded and subsequently relapsed (Abstract 203); a multicenter prospective analysis of circulating tumor DNA in diffuse large B-cell lymphoma patients who had relapsed after treatment with axicabtagene ciloleucel (Abstract 884); and the early use of corticosteroids to prevent toxicities in patients in cohort 4 of the ZUMA-1 trial (Abstract 243).
Dr. Hill reported consulting with Juno/Celgene/BMS and Novartis and research and consulting for Kite/Gilead. Dr. Locke reported consulting for Cellular Biomedicine Group and being a scientific adviser to Kite/Gilead, Novartis, Celgene/BMS, GammaDelta Therapeutics, Calibr, and Allogene. Dr. Riedell reported consulting for Bayer and Verastem, consulting for and research funding from Novartis and BMS/Celgene, and consulting for, research funding from, and speaking for Kite.

EXPERT ANALYSIS FROM ASH 2019
Parkinson’s patients can lose swimming ability after deep brain stimulation
Successful deep brain stimulation of the subthalamic nucleus may have unforeseen effects on the ability to swim in some patients with Parkinson’s disease, according to findings from a case series of nine patients published in Neurology.
All nine patients in the report were experienced swimmers, including two who competed in several competition-level races. They reported losing their ability to swim after successful deep brain stimulation of the subthalamic nucleus (STN-DBS) procedures. The Neurology paper focuses on three of the patients.
All of the patients achieved good to excellent motor control and cut their L-dopa dosage by impressive amounts. But they also lost the ability to coordinate limb movement when in the water, reported Daniel Waldvogel, MD, of the University of Zurich, and associates.
“All found their ability to swim came back immediately, with improved coordination of the limbs,” when stimulation was discontinued, the team noted. But soon after the stimulation ceased, their motor symptoms also rapidly returned, leading all to resume continuous stimulation.
One possible explanation is that STN-DBS does not strongly improve dopamine levels in the supplementary motor area, which controls independent limb movements.
It “may be that DBS affects the supplementary motor area (SMA) differently than levodopa. The SMA is a main output area of the basal ganglia, with connections to the primary motor cortex and the spinal cord,” wrote Dr. Waldvogel and associates. “Functionally, the SMA is thought to be crucial for facilitating independent movements of the limbs, which is a key requirement for swimming.”
Although the SMA also partly manages gait, walking was unaffected in all nine of the patients.
The authors described three patients in more detail:
- Case 1 was a 69-year-old man who was a proficient swimmer before DBS. His Unified Parkinson’s Disease Rating Scale (UPDRS) motor score on medication fell from 28 with dyskinesia before DBS to 17 after DBS, and his levodopa-equivalent dosage declined from 1,570 mg to 920 mg. The man almost drowned after he jumped into a lake and had to be rescued by another swimmer.
- Case 4 was a 59-year-old woman who was an accomplished and competitive swimmer and had been swimming up until the DBS procedure. After DBS, her UPDRS motor score on medication fell from 9 with dyskinesia to 6, and her levodopa-equivalent dosage dropped from 825 mg to 150 mg. She had good motor outcome after DBS but lost the ability to swim. “She regularly practiced swimming with her physiotherapist, but never came close to her previous level,” the authors said.
- Case 5 was a 61-year-old woman who was a competitive swimmer, including swimming across Lake Zurich, and held a lifesaving certification. Her UPDRS motor score on medication fell from 11 with dyskinesia to 9, and her levodopa-equivalent dosage decreased from 800 mg to 180 mg. After DBS, she could swim only a quarter of a kilometer and complained of “awkward posture” during her efforts.
The phenomenon has been reported just one other time by a group from the University of Western Australia. This reported patient was a 68-year-old man with a 5-year history of medication-refractory, tremor-predominant Parkinson’s. He received DBS of the posterior subthalamic area (PSA-DBS).
The patient was a dedicated lap swimmer at his local pool. When he returned to his hobby, “he quickly realized he could not propel himself adequately and that he required assistance to get to safety. In a supervised swimming situation, he was unable to float or perform freestyle, breaststroke, or back stroke. With the stimulator turned off for 30 minutes, he regained swimming ability and lost it when the stimulator was turned on.
The Australian team noted that three similar cases presented to them, but they did not discuss those cases in the paper.
Dr. Waldvogel and coauthors wrote that they might also have unreported cases in their cohort of patients with STN-DBS.
“Our cohort of patients with PD who underwent STN-DBS at the time of this retrospective study consisted of 217 patients, but we did not assess patients systematically for their swimming skills or loss thereof,” the authors said. “Until the mechanism of the reported deterioration of the ability to swim after STN-DBS is elucidated, it is crucial that we advise patients of the potential risk of drowning and the need for a carefully supervised assessment of their swimming skills before going into deep water.”
The report received no funding, and one author disclosed financial relationships with industry.

She had good motor outcome after DBS but lost the ability to swim. “She regularly practiced swimming with her physiotherapist, but never came close to her previous level,” the authors said.
- Case 5 was a 61-year-old woman who was a competitive swimmer, including swimming across Lake Zurich, and held a lifesaving certification. Her UPDRS motor score on medication fell from 11 with dyskinesia to 9, and her levodopa-equivalent dosage decreased from 800 mg to 180 mg. After DBS, she could swim only a quarter of a kilometer and complained of “awkward posture” during her efforts.
The phenomenon has been reported just one other time by a group from the University of Western Australia. This reported patient was a 68-year-old man with a 5-year history of medication-refractory, tremor-predominant Parkinson’s. He received DBS of the posterior subthalamic area (PSA-DBS).
The patient was a dedicated lap swimmer at his local pool. When he returned to his hobby, “he quickly realized he could not propel himself adequately and that he required assistance to get to safety. In a supervised swimming situation, he was unable to float or perform freestyle, breaststroke, or back stroke. With the stimulator turned off for 30 minutes, he regained swimming ability and lost it when the stimulator was turned on.
The Australian team noted that three similar cases presented to them, but they did not discuss those cases in the paper.
Dr. Waldvogel and coauthors wrote that they might also have unreported cases in their cohort of patients with STN-DBS.
“Our cohort of patients with PD who underwent STN-DBS at the time of this retrospective study consisted of 217 patients, but we did not assess patients systematically for their swimming skills or loss thereof,” the authors said. “Until the mechanism of the reported deterioration of the ability to swim after STN-DBS is elucidated, it is crucial that we advise patients of the potential risk of drowning and the need for a carefully supervised assessment of their swimming skills before going into deep water.”
The report received no funding, and one author disclosed financial relationships with industry.

Successful deep brain stimulation of the subthalamic nucleus may have unforeseen effects on the ability to swim in some patients with Parkinson’s disease, according to findings from a case series of nine patients published in Neurology.
All nine patients in the report were experienced swimmers, including two who competed in several competition-level races. They reported losing their ability to swim after successful deep brain stimulation of the subthalamic nucleus (STN-DBS) procedures. The Neurology paper focuses on three of the patients.
All of the patients achieved good to excellent motor control and cut their L-dopa dosage by impressive amounts. But they also lost the ability to coordinate limb movement when in the water, reported Daniel Waldvogel, MD, of the University of Zurich, and associates.
“All found their ability to swim came back immediately, with improved coordination of the limbs,” when stimulation was discontinued, the team noted. But soon after the stimulation ceased, their motor symptoms also rapidly returned, leading all to resume continuous stimulation.
One possible explanation is that STN-DBS does not strongly improve dopamine levels in the supplementary motor area, which controls independent limb movements.
It “may be that DBS affects the supplementary motor area (SMA) differently than levodopa. The SMA is a main output area of the basal ganglia, with connections to the primary motor cortex and the spinal cord,” wrote Dr. Waldvogel and associates. “Functionally, the SMA is thought to be crucial for facilitating independent movements of the limbs, which is a key requirement for swimming.”
Although the SMA also partly manages gait, walking was unaffected in all nine of the patients.
The authors described three patients in more detail:
- Case 1 was a 69-year-old man who was a proficient swimmer before DBS. His Unified Parkinson’s Disease Rating Scale (UPDRS) motor score on medication fell from 28 with dyskinesia before DBS to 17 after DBS, and his levodopa-equivalent dosage declined from 1,570 mg to 920 mg. The man almost drowned after he jumped into a lake and had to be rescued by another swimmer.
- Case 4 was a 59-year-old woman who was an accomplished and competitive swimmer and had been swimming up until the DBS procedure. After DBS, her UPDRS motor score on medication fell from 9 with dyskinesia to 6, and her levodopa-equivalent dosage dropped from 825 mg to 150 mg. She had good motor outcome after DBS but lost the ability to swim. “She regularly practiced swimming with her physiotherapist, but never came close to her previous level,” the authors said.
- Case 5 was a 61-year-old woman who was a competitive swimmer, including swimming across Lake Zurich, and held a lifesaving certification. Her UPDRS motor score on medication fell from 11 with dyskinesia to 9, and her levodopa-equivalent dosage decreased from 800 mg to 180 mg. After DBS, she could swim only a quarter of a kilometer and complained of “awkward posture” during her efforts.
