VIDEO: Diabetes patients achieve lipid goals on alirocumab
BOSTON – The PCSK9 inhibitor alirocumab was superior to ezetimibe in meeting multiple lipid goals In patients with type 2 diabetes, according to results from a pooled analysis of randomized clinical trials.
“Alirocumab is an efficient therapy to get patients at target, which is our clinical daily business and the reason to treat patients,” said investigator Dirk Müller-Wieland, MD, an internist at University Hospital Aachen, Germany.
Dr. Müller-Wieland and his colleagues conducted a pooled analysis of 407 individuals with type 2 diabetes enrolled in one of three randomized trials who had hypercholesterolemia despite background lipid-lowering treatments. They found a total of 241 patients with diabetes who had received alirocumab in the trials, and 166 who had received ezetimibe.
With alirocumab on top of statins, 75.0% of patients met a combined LDL cholesterol, non–HDL cholesterol, and apolipoprotein B threshold after 24 weeks of treatment, compared with 56.7% of patients receiving ezetimibe along with their statins, a significant difference, it was reported at the annual meeting of the American Association of Clinical Endocrinologists.
The proportion of patients achieving LDL levels of less than 70 or 100 mg/dL (depending on cardiovascular risk) was significantly larger in the alirocumab group than in the ezetimibe group, at 80.8% versus 64.3%, Dr. Müller-Wieland reported.
In patients with extreme cardiovascular risk, the proportion of patients achieving LDL levels of less than 55 mg/dL was 66.0% in the alirocumab group, compared with 36.6% in the ezetimibe group, suggesting the PCSK9 inhibitor was “much more efficient than ezetimibe” in reaching that goal, Dr. Müller-Wieland said in a video interview.
For patients in the extreme cardiovascular risk category, as defined in recent guidelines, the AACE recommends a new LDL treatment goal of less than 55 mg/dL, Dr. Müller-Wieland noted.
Significant differences in favor of alirocumab were also reported for the proportion of patients achieving non-HDL and ApoB goals, the report showed.
Adverse events related to treatment occurred in a similar proportion of patients in the alirocumab and ezetimibe groups, according to the investigators.

Three days of beta-lactam beat clinically stable CAP
MADRID – Three days of beta-lactam therapy was just as effective as 8 days for clinically stable patients presenting with community-acquired pneumonia.
In a randomized, placebo-controlled trial, 15-day cure rates were 69.9% in patients who took 3 days of antibiotics and 61.2% in those who took 8 days – a nonsignificant difference, Aurélien Dinh, MD, said at the European Society of Clinical Microbiology and Infectious Diseases annual congress.
“Reducing treatment time now appears to be manageable and effective in a number of infectious diseases,” Dr. Dinh explained. “Although there are some limits, surely, this change in practice might lead to reduced rates of multidrug-resistant bacteria, fewer adverse events, and surely lower costs.”
The French PTC Trial (Short Duration Treatment of Non-Severe Community-Acquired Pneumonia) randomized 310 patients (mean age, 73.5 years) to either short- or long-course treatment with a beta-lactam antibiotic. Patients were eligible for the study if they were admitted to the hospital for community-acquired pneumonia based on respiratory signs, fever of 38° C or higher, and evidence of new infiltrate on chest radiograph.
All patients were treated with 3 days of amoxicillin/clavulanic acid (Augmentin) or third-generation cephalosporin. Those who had responded clinically by day 3 entered the 5-day randomization period, receiving placebo or 5 more days of active therapy with the same agent.
Clinical requirements for randomization included being afebrile with stable heart and respiratory rate, a systolic blood pressure of at least 90 mm Hg, and oxygen saturation of at least 90%.
The primary endpoint was clinical cure at day 15: no fever, absence of or improvement in respiratory symptoms (dyspnea, cough, purulent sputum, and cackles), and no need for additional antibiotic treatment for any indication.
Secondary endpoints were cure at day 30, 30-day mortality, adverse events, length of stay, return to usual activities by day 30, and quality of life at day 30.
Many of the generally elderly patient cohort had comorbid illnesses, including diabetes (about 20%), chronic obstructive pulmonary disease (about 35%), and coronary insufficiency (about 14%). About 20% were active smokers. Less than 10% had gotten a pneumococcal vaccine in the past 5 years.
At admission, more than half of patients were dyspneic, 80% had cough, and 39% had purulent sputum. The median PSI/PORT Score was 82.
After 3 days of treatment, clinical cure was not significantly different between the 3- and 8-day groups, either in the intent-to-treat analysis (69.9% vs. 61.2%) or in the per-protocol analysis (75.7% vs. 68.7%).
Because the trial had closed days before the ECCMID meeting, only the primary endpoints were available for discussion, Dr. Dinh said. Investigators are analyzing the secondary endpoint data, which he said would be published at a later date.
Despite the positive results, Dr. Dinh cautioned against using the study as justification for a one-size-fits-all treatment for community-acquired pneumonia.
“Although I think we demonstrated that 3 days of treatment with beta-lactam is not inferior to 8 days, this cannot be imposed without regard to individual patient status,” he cautioned. Such a treatment paradigm would not be advisable for patients with moderately severe pneumonia, who were excluded from the study, or those with compromised immune systems.
Nor does Dr. Dinh expect wholesale clinical embracing of the encouraging results, which bolster the ever-accumulating data in favor of shorter courses of antibiotics for some infectious diseases.
“I think there is a chance that clinicians who normally treat for 9 or 10 days may now feel comfortable reducing to 7,” he said with a chuckle.
The French Ministry of Health sponsored the study. Dr. Dinh had no competing financial interests.

VIDEO: Pills alone not the answer for pain management
SANDESTIN, FLA. – More than ever, clinicians need to rely on a multimodal approach to pain management, Katherine Galluzzi, DO, said at the annual Congress of Clinical Rheumatology.
In the era of opioid addiction – in which she said physicians have sometimes been unfairly vilified – pharmaceutical options are limited not only by the threat of abuse but also by governmental regulation, explained Dr. Galluzzi, chair of geriatrics at the Philadelphia College of Osteopathic Medicine.
The underpinning of pain management in the future will need to be cognitive-behavioral therapy, such as changing behavior and meditation; physical approaches, such as exercise and acupuncture; and interventional treatments, such as nerve blocks and trigger-point injections. Pharmacotherapy can’t do it all, nor should it, she said.
“This is what we have, this is what we need to do,” Dr. Galluzzi said. “This impacts the quality of life, and patients need to begin providing self-care. It’s not going to come in the form of a pill. It has to be a commitment between the patient and the physician.”
The Centers for Medicare & Medicaid Services are proposing a new limit on opioid prescriptions for Medicare recipients – a maximum of 90 morphine mg equivalents per day for no more than 7 days. That will affect older people, who are most likely to be in need of pain management, she said. Those on hospice care and experiencing certain cancer pain will be exempt, she noted in an interview.
Concerns about addiction to drugs such as gabapentin and benzodiazepines might make these therapies less of an option in coming years, Dr. Galluzzi added.
Risk evaluation and mitigation strategy training is an important tool for helping physicians weigh the benefits and the risks of opioid prescriptions. Dr. Galluzzi particularly suggests enrolling in a 3-4 hour, in-person program, saying that it’s well worth the time.
“If you haven’t done a risk assessment and mitigation strategies course and you’re an opioid prescriber,” she said, “I highly recommend that you do that.”

EXPERT ANALYSIS FROM CCR 18
VIDEO: Characteristic flora define intestinal microbiome in scleroderma
SANDESTIN, FLA. – Scleroderma patients appear to have a characteristic microbiome composition, which is consistent in samples taken around the world.
These patients showed decreased populations of beneficial commensal flora and increased populations of proinflammatory species, Elizabeth Volkmann, MD, said at the annual Congress of Clinical Rheumatology.
Furthermore, specific species seem to correlate with specific gastrointestinal symptoms, said Dr. Volkmann of the University of California, Los Angeles. “Features also unexpectedly overlap with the consortium typical for Crohn’s disease, a disease with both inflammatory and fibrosing phenotype,” she said.

Her recent exploration of this topic included 17 patients with scleroderma and GI symptoms and 17 matched healthy controls (BMJ Open Gastro. 2017;3:e000134). Everyone underwent a bowel prep and colonoscopy, during which cecum and sigmoid mucosal lavage samples were obtained. Those samples underwent RNA sequencing.
In addition to quantifying the species present, Dr. Volkmann sought to associate populations with symptoms. The primary assessment tool was the GIT 2.0, which measures distention/bloating; diarrhea; fecal soilage; constipation; emotional well-being; and social functioning.
Similar to the findings in inflammatory disease states, scleroderma patients had decreased levels of commensal Clostridia, a class of Firmicutes that is established in early infancy and very important in the maintenance of gut homeostasis. They also showed a decreased proportion of Faecalibacterium, a genus with anti-inflammatory activity; this finding has been observed in patients with Crohn’s disease.
Patients also showed relative increases in pathobionts. These are potentially pathological organisms that, under normal circumstances, live symbiotically. Janet Chow, PhD, who coined the term in a 2011 paper, said these species are typically proinflammatory (Curr Opin Immunol. 2011 Aug; 23[4]:473-80).
“Organisms proposed as pathobionts are associated with chronic inflammatory conditions – unlike opportunistic pathogens, which often cause acute infections and are typically acquired from the environment or other parts of the body. In addition, pathobionts are innocuous to the host under normal conditions,” wrote Dr. Chow of the California Institute of Technology, Pasadena.
In Dr. Volkmann’s study, Bifidobacterium and Lactobacillus, which are usually reduced in proinflammatory disorders, were relatively abundant in patients, compared with controls.
She noted specific associations with both symptoms. Parabacteroides and Enterobacteriaceae were associated with increased constipation. Prevotella was associated with increased diarrhea and increased distention/bloating.
Her results are consistent with a Swedish study (Arthritis Res Ther. 2016 Nov 1;18[1]:278) and three Italian studies conducted in Rome, Milan, and Piacenza.
“It’s fascinating that we seem to be identifying a consistent microbiome profile for scleroderma patients,” Dr. Volkmann said.
Dr. Volkmann had no relevant financial disclosures.

Her results are consistent with a Swedish study (Arthritis Res Ther. 2016 Nov 1;18[1]:278) and three Italian studies conducted in Rome, Milan, and Piacenza.
“It’s fascinating that we seem to be identifying a consistent microbiome profile for scleroderma patients,” Dr. Volkmann said.

Malignant pleural mesothelioma guidelines often are ignored
SAN DIEGO – National guidelines for the treatment of malignant pleural mesothelioma often are not followed, a new study showed, with fewer than one-third of patients receiving cancer-directed surgery.
Another 32% received no treatment, although that didn’t seem to have an impact on median months of survival.
Still, “there can be a wide variation in median survival time, depending on clinical factors and tumor characteristics,” said study coauthor Harmik Soukiasian, MD, of Cedars-Sinai Medical Center, Los Angeles. “Given the variation in prognosis, it is quite astonishing that over 30% of MPM patients are not receiving any form of treatment. As clinicians armed with these data, we need to investigate why that is.”
Dr. Soukiasian presented the study findings at the annual meeting of the American Association for Thoracic Surgery.
MPM, a rare cancer, is mainly linked to asbestos exposure. “MPM is almost always a fatal disease, and the prognosis can only be modestly influenced by oncological treatments,” according to the authors of guidelines released in 2013. “The diagnostic process can be complex, with highly specialized advice frequently required to arrive at a definite diagnosis. Treatment varies from therapeutic nihilism to radical combined-modality treatment approaches” (J Thorac Dis. 2013 Dec;5[6]:E254-E307).
Surgical resection is a controversial treatment for MPM, Dr. Soukiasian said. It is “based on the principle of macroscopic resection of solid tumor with adjuvant therapy to treat micrometastatic disease,” he explained. “Cancer-directed surgery for MPM is usually reserved for localized epithelial type histology and is associated with a 5-year survival rate of 15%.”
For the new study, the investigators tracked 3,834 patients in the National Cancer Database (2004-2014) diagnosed with MPM clinical stages I-III. Most had epithelioid MPM (69%), with sarcomatoid (17%) and mixed subtype (15%) making up the rest. They examined whether patient treatment complied with the National Comprehensive Cancer Network (NCCN) guidelines, which recommend surgery in resectable epithelioid MPM.
“Our study revealed significant lack of compliance with NCCN guidelines, as well as many disparities in the management of MPM,” Dr. Soukiasian said. “For the overall cohort, 32.3% of patients did not receive any treatment, 18.1% had surgery plus chemotherapy, 38.6% chemotherapy alone, and only 7% received trimodality therapy. In patients with epithelial histology, surgery was significantly underutilized, with only 30% of patients receiving cancer-directed surgery.”
In addition, he said, “our study reveals several disparities that affect compliance with NCCN guidelines. Treatment disparities were observed in women, octogenarians, the uninsured, the Medicaid-insured, and in patients with comorbidities. Guideline adherence was significantly increased in academic and high-volume hospitals with an associated increase in survival.”
But the study also found that median survival estimates were similar regardless of treatment: 10 months for no treatment, 15 months for chemotherapy only, 17 months for surgery only, and 22 months for surgery plus chemotherapy.
During the AATS presentation, an audience member asked about how performance status – a measure of a person’s ability to perform everyday activities – affects the eligibility for surgery.
“It’s quite common for low performance status to exclude someone from surgery,” the audience member said. “Some of these patients are very sick.”
Dr. Soukiasian acknowledged that performance status was not included in the data. The study was focused on the gap between guidelines and real-world practice, and generated questions of why and about the potential opportunity for improved treatment of these patients.
How do patient choices, cost, and quality of life factor in? “These are very important questions and concerns,” Dr. Soukiasian said. “Although our research does not provide data or conclusions on quality of life or cost, these topics will be important to address in follow-up studies to elucidate possible barriers in the treatment of MPM and the initiation of future educational opportunities for our patients.”

Novel x-ray score distinguishes psoriatic arthritis from osteoarthritis of the hand
LIVERPOOL, ENGLAND – A novel radiologic scoring system differentiated psoriatic arthritis (PsA) from nodal osteoarthritis (OA) of the hand in a pilot study.
“It’s a dilemma that’s faced, perhaps every couple of weeks, by most [rheumatologists]: Is it osteoarthritis or is it early psoriatic arthritis?” said Sardar Bahadur, MD, at the British Society for Rheumatology annual conference.
Both conditions are seen in daily practice, although the prevalence of hand OA is less frequent than knee OA. Approximately one in five of all adults in the United Kingdom have OA and 1%-2% have psoriasis. Of these, the prevalence of hand OA is about 11% and 0.1%-0.3% have psoriatic arthritis.
Being able to differentiate between the two conditions has important consequences for treatment, Dr. Bahadur said.
“Getting the diagnosis wrong could have major implications,” he said. “If you miss psoriatic arthritis, then potentially you are going to find irreversible joint damage causing pain and disability, and the opposite is also true, with misdiagnosis of osteoarthritis, with overuse of immunosuppression and all the cost implications as well as medicolegal consequences.”
Dr. Bahadur of the department of rehabilitation medicine and rheumatology at the Defence Medical Rehabilitation Centre Headley Court, in Epsom, England, added: “So early diagnosis is very important, it means early treatment, it means better care, potentially preventing serious and irreversible damage.”
Together with researchers at Guy’s and St Thomas’ NHS Trust, London, Dr. Bahadur hypothesized that changes in hand x-rays were distinct and could be reliably used to differentiate between the two conditions. They developed a scoring system for hand radiographs that looked at the differences in the interphalangeal joints, soft tissue, and bone features of patients with known OA or PsA.
Dr. Bahadur noted that the aim was to focus on plain film radiographs of the hands because these were inexpensive, universally accessible, did not rely on radiologists’ interpretation, and changes in the hands were known to occur in both OA and PsA.
A total of 99 sets of hand x-rays taken between 2008 and 2016 from 50 patients with OA and 49 patients with PsA were obtained. These were anonymized and then analyzed by a musculoskeletal radiologist using the scoring system the team had developed. The radiologist was unaware of the patients’ clinical status. The results were then compared to the clinical diagnosis.
The novel method of scoring each x-ray was then taught to two rheumatology and one radiology trainee during a 1-hour training session and were then asked to score the same radiographs.
Dr. Bahadur reported that the radiologist reported normal hand radiographs in five patients and, of the remaining 94 sets of left- and right-hand radiographs, the scoring system correctly allocated 100% of images to either PsA, OA, or rheumatoid arthritis (RA).
Of note was that the radiologist correctly identified two patients with nodal hand OA who later developed PsA several years later, and one patient with RA who was initially thought to have PsA.
“The system could be successfully used by nonradiologists,” Dr. Bahadur proposed. There was good agreement between the scoring system results and the clinical diagnosis then used by the trainees, with 88% and 67% of the radiographs correctly matched to the clinical diagnosis by the rheumatology trainees, and 70% for the radiology trainee.
Dr. Bahadur noted that the features that were consistently identified as being different between hand OA and PsA patients were soft tissue changes, such as dactylitis, as well as erosions, new bone formation, and other features such as subchondral surface changes and cysts.
The results of this single-center study show that the novel radiologic scoring system of hand radiographs was effective at differentiating patients with PsA from nodal OA.
“The ambition is to make this usable by nonradiologists,” Dr. Bahadur said. A multicenter trial would be the next step to look at the use of the scoring system.
Dr. Bahadur had no conflicts of interest to disclose.

Patidegib, the first topical hedgehog inhibitor, scores in Gorlin syndrome
CHICAGO – in a phase 2 study, and did so without causing the problematic adverse events that prompt many Gorlin patients to discontinue systemic hedgehog inhibitor drugs, Ervin Epstein Jr., MD, said at the annual meeting of the American College of Mohs Surgery.
He characterized patidegib, a small-molecule cyclopamine derivative, as “a Goldilocks drug, a topical hedgehog inhibitor with percutaneous absorption that’s just right: sufficient to have anti-hedgehog and anti–basal cell carcinoma efficacy, but not enough to cause systemic exposure or systemic adverse events.”
A complete response – tumor clinical disappearance – occurred in 25% of the BCCs in the two active treatment arms. In contrast, none of the BCCs in the control group cleared. Patients on patidegib developed one or more new surgically eligible BCCs after study week 2 at a rate of 0.4 tumors per patient, markedly less than the rate of 1.4 tumors per patient in controls.
“We think that prevention is really the place to go with this drug,” said Dr. Epstein, cofounder and chief medical officer at PellePharm, the company based in Menlo Park, Calif., that is developing patidegib.
Indeed, he envisions patidegib gel as lifetime therapy for Gorlin patients.
Tumor shrinkage was significantly greater with 2% patidegib than with the 4% concentration. But so was treatment adherence: Patients in the 2% patidegib arm missed on average just 2 days of therapy over the course of 6 months, while those in the 4% arm missed 50 days. Dr. Epstein attributed this discrepancy to a freak of randomization that can occur in such a small study: 5 of 6 patients in the 2% patidegib group were women, while most in the 4% arm were men. And the men were far less adherent to treatment, possibly because men are less accustomed to applying a product on their face daily, he noted.
In any case, it’s the 2% gel formulation that is moving on to a phase 3, double-blind, randomized trial. The 150-patient U.S. and European study, scheduled to start this summer, will have as its primary endpoint the rate of new BCCs over the course of 1 year. The Food and Drug Administration has granted topical patidegib Breakthrough Drug and Orphan Drug status.
Dr. Epstein said that, in the phase 2 study, BCC shrinkage occurred only in patients whose hedgehog pathway activity decreased after 6 weeks of topical therapy as evidenced by a reduction in the GLI1 mRNA biomarker. Of note, circulating blood levels of patidegib in study participants were more than 500-fold lower than when the drug is given orally. And of greatest importance, rates of the hallmark side effects of oral hedgehog inhibitor therapy that cause so many patients to discontinue therapy – muscle cramps, taste loss, and hair loss – were no different in patients on patidegib gel than in those on placebo.
“In the randomized trial of vismodegib [Erivedge], half of patients stopped taking it within 1 year despite good results. And indeed, when they stopped taking the drug, the basal cell carcinomas returned,” the dermatologist noted.

The 150-patient U.S. and European study, scheduled to start this summer, will have as its primary endpoint the rate of new BCCs over the course of 1 year. The Food and Drug Administration has granted topical patidegib Breakthrough Drug and Orphan Drug status.
Dr. Epstein said that, in the phase 2 study, BCC shrinkage occurred only in patients whose hedgehog pathway activity decreased after 6 weeks of topical therapy as evidenced by a reduction in the GLI1 mRNA biomarker. Of note, circulating blood levels of patidegib in study participants were more than 500-fold lower than when the drug is given orally. And of greatest importance, rates of the hallmark side effects of oral hedgehog inhibitor therapy that cause so many patients to discontinue therapy – muscle cramps, taste loss, and hair loss – were no different in patients on patidegib gel than in those on placebo.
“In the randomized trial of vismodegib [Erivedge], half of patients stopped taking it within 1 year despite good results. And indeed, when they stopped taking the drug, the basal cell carcinomas returned,” the dermatologist noted.
Dr. Epstein is an employee of PellePharm, which is developing patidegib. Dermatologists with patients with Gorlin syndrome who are interested in participating in the phase 3 trial can contact him at [email protected].

Sulforaphane for autism? Maybe
LOS ANGELES –
Sulforaphane is a compound in cruciferous vegetables, especially 3-day-old broccoli sprouts. It’s sold widely online and in stores, often as broccoli sprout extract, for anticancer and other effects.
The idea of using it for autism came about after investigators noticed that, in the lab, it induced some of the cellular changes associated with fever, including upregulation of heat shock proteins, according to Kanwaljit Singh, MD, a pediatrics instructor at the University of Massachusetts, Worcester.
Fever has been reported to improve autism symptoms. So, several years ago, “we decided to do a pilot study with sulforaphane” to see if it had a similar effect, Dr. Singh said at the annual meeting of the American Academy of Neurology.
At 18 weeks, 29 young autistic men randomized to the supplement outperformed 15 randomized to placebo on the Aberrant Behavior Checklist and other measures. It was the first study of sulforaphane for autism, and it got a good deal of press attention when it was published in 2014; Dr. Singh was the lead author (Proc Natl Acad Sci U S A. 2014 Oct 28;111[43]:15550-5).
“Because we had a very good signal in our pilot study, we decided to do a slightly larger, slightly more complex clinical trial, which is ongoing right now,” he said. The results aren’t due until the second half of 2018, but he gave an interim report at the meeting.
There are 50 children with autism in the new study, aged 3-12 years. Half are randomized to sulforaphane, half to placebo, for the first 15 weeks, then all are switched to open-label sulforaphane for 15 weeks more, followed by a 6-week washout period.
The randomized portion is still blinded. But so far, 31% have responded positively at 15 weeks, meaning a much or very much improved score in at least two domains on the Ohio Autism Clinical Global Impressions Scale; domains cover social interaction, violent behavior, communication, and other areas.
Among the patients who have completed the study, the response rate at week 30 almost doubled, to 56%. “We don’t know which patients were on sulforaphane and which were on placebo” in the randomized phase, Dr. Singh said. “But we think because the response doubled” when the second half of the children were switched to sulforaphane, “there should probably not be a very large placebo effect here.”
Meanwhile, after the washout period, “some patients still do well, but many more [go] back to baseline,” added Dr. Singh, the senior investigator in the new trial.
The most common side effects are insomnia (28%), vomiting (19%), flatulence (17%), diarrhea (15%), and constipation (13%). A few patients have dropped out because of insomnia and diarrhea; more have dropped out because they simply didn’t want to take the pills – 125 mg of broccoli seed powder three to eight times a day, depending on weight.
Other groups are looking into sulforaphane, too – not just for autism, but also for schizophrenia, prostate cancer, and other indications.
The U.S. Department of Defense is funding the research. The investigators said they have no relevant disclosures.

Adjuvant trastuzumab for breast cancer: 6 months may suffice
Shortening the duration of adjuvant trastuzumab (Herceptin) therapy for early-stage HER2+ breast cancer from the current standard of 12 months to 6 months yields similar efficacy but halves the incidence of cardiac toxicity, the PERSEPHONE trial found.
“In 2005, trastuzumab was licensed with a standard of three weekly injections for 12 months, and this was the duration used empirically in pivotal registration studies,” lead study author Helena Earl, MD, professor of clinical cancer medicine at the University of Cambridge, England, said in a press briefing leading up to the annual meeting of the American Society of Clinical Oncology.
However, cardiac toxicity has been particularly problematic with this regimen. Furthermore, the Fin-HER trial, while small, suggested that only 9 weeks of adjuvant trastuzumab was possibly as efficacious (N Engl J Med. 2006 Feb;354[8]:809-20).
Dr. Earl and her coinvestigators enrolled in their phase 3 noninferiority, randomized, controlled trial 4,089 women with early-stage HER2+ breast cancer, randomizing them to either 6 months or 12 months of trastuzumab, mapped onto standard U.K. real-world practice.
The main findings showed that the 4-year rate of disease-free survival, the trial’s primary endpoint, was nearly 90% in both groups, with the absolute difference of just 0.4% falling well within the predefined 3% margin for noninferiority.
Moreover, the rate of stopping trastuzumab because of cardiotoxicity was half as high with the shorter-duration therapy; patients in that arm had more rapid recovery of cardiac function, too.
“The PERSEPHONE trial’s first results demonstrate that 6 months of adjuvant trastuzumab is noninferior to 12 months; 6 months, compared with 12 months, of treatment reduces cardiac and other toxicities and costs both to patients and health care systems,” Dr. Earl summarized. “We are confident [these results] will mark the first steps towards reduction of treatment duration for many women with HER2+ breast cancer.”
The investigators are still analyzing quality of life, patient-reported outcomes, and health economic data, she said. In addition, they are performing translational studies to look for biomarkers that may identify subgroups who fare better with one or the other duration of trastuzumab.
Will the standard change?
At present, the PERSEPHONE findings are not sufficient to change the existing standard of care of 12 months of adjuvant trastuzumab, according to Dr. Earl. “We need to be very careful and cautious about coming out at this point and saying, ‘Yes, 6 months is enough,’ ” she maintained. “At the moment, I do think we need to wait for longer follow-up and we need to take a real close look at the data. Changing from an established treatment that works is always going to be a very complex and very challenging thing to do.”
“Personally, I find the results quite compelling, and I think that it is likely that they will signal a shift even in the U.S. oncology community toward shorter duration of Herceptin adjuvant therapy,” commented Richard L. Schilsky, MD, FACP, FASCO, chief medical officer of ASCO and press briefing moderator. However, “we don’t have data yet on overall survival. Survival in this study is still relatively short for a breast cancer population, although patients with HER2+ disease oftentimes have a somewhat more aggressive course,” he noted. In addition, the ongoing translational studies will be critical to any decisions about changing the standard of care because some subgroups of patients will probably not fare as well with the shorter-duration therapy.
U.S. payers are unlikely to start covering only 6 months of trastuzumab unless the drug’s label is changed based on new data or clinical practice guidelines begin to endorse that shorter duration, according to Dr. Schilsky. “Until one of those things occurs, there is not really a rationale for a payer to mandate that a physician undertake a course of treatment that they may not think is in the patient’s best interest,” he elaborated.
As roughly 12% to 15% of women with early breast cancer have HER2+ disease, the PERSEPHONE findings could have considerable implications for treatment costs, noted Bruce E. Johnson, MD, FASCO, president of ASCO.
However, longer follow-up will be needed before any change to the standard is made, he agreed. “One has to be circumspect about how long you wait and how much more data one has before making a definitive statement. With 8% deaths and 12% recurrences, it may be a bit early to make a definite change in practice.”
While important, the more favorable safety of the 6-month therapy is not sufficient, according to Dr. Johnson, who is also a professor of medicine at the Dana-Farber Cancer Institute and a leader of the Dana-Farber/Harvard Cancer Center Lung Cancer Program, both in Boston. “In my opinion, the efficacy drives most of the therapeutic decision making. We are encouraged by this, and 5-year follow-up is certainly a reasonable initial step. But to be sure of the efficacy, you probably need a bit more time and a few more events,” he explained.
Study details
Patients enrolled in PERSEPHONE had stage Ia to IIIa breast cancer. They were randomized evenly to either 6 months (9 cycles) or 12 months (18 cycles) of adjuvant trastuzumab, given with or after completion of chemotherapy.
Main results showed that the 4-year rate of disease-free survival was 89.8% with 12 months of trastuzumab and 89.4% with 6 months of trastuzumab (hazard ratio, 1.07; P for noninferiority = .01), Dr. Earl reported.
Cardiotoxicity data for the trial population, previously reported (Br J Cancer. 2016 Dec 6;115[12]:1462-70), showed that the rate of stopping trastuzumab because of this adverse effect was 8% with the standard-duration therapy and 4% with the shorter-duration therapy (P less than .0001). Patients saw recovery of cardiac function after stopping the drug (P less than .0001), with more rapid recovery in the shorter-duration group (P = .02).
The group given 6 months of trastuzumab also had lower rates of grade 3 or 4 cough, fatigue, pain, chills, and palpitations, problems which patients reported were having an impact on their lives, Dr. Earl noted. “Perhaps more importantly, patients given 6 months of treatment will be able to return more quickly to their normal lives once their treatment is completed.”
Dr. Earl disclosed that she has a consulting or advisory role with Celgene, Pfizer, Roche, and AstraZeneca; receives travel, accommodations, or expenses, and receives honoraria from Pfizer, Daiichi Sankyo, Amgen, and AstraZeneca; and receives research funding from Roche and Sanofi Pasteur. The study was funded by the National Institute for Health Research in the United Kingdom.

Specialty practices hire more physician assistants and nurse practitioners
based on data from a review of approximately 90% of physician practices in the United States.
The employment of advanced practice clinicians in primary care continues to grow, but their presence in specialty practices has not been well studied, wrote Grant R. Martsolf, PhD, of the University of Pittsburgh, and his colleagues. In a study published in JAMA Internal Medicine, the researchers used the proprietary SK&A data set to examine employment in specialty practices between 2008 and 2016.
Overall, 28% of all specialty practices employed advanced practice clinicians in 2016 – a 22% increase from 2008. Nearly half of multispecialty practices (49%) employed advanced practice clinicians, as did at least 25% of dermatology, cardiology, obstetrics-gynecology, orthopedic surgery, and gastroenterology practices.
Plastic surgery and ophthalmology practices were the least likely to employ advanced practice clinicians. Surgical practices were more likely to employ physician assistants than nurse practitioners, but the other specialty practices were more likely to employ NPs than PAs.
The growth in employment of advanced practice clinicians may be driven by factors such as economics and the expanding roles for advanced practice clinicians in specialty practice, the researchers said.
The findings were limited by the inclusion of outpatient providers only, and by the lack of information about the exact duties of advanced practice clinicians in each practice, the researchers noted. However, the results suggest that advanced practice clinicians will become even more prevalent in specialty care, and “future research will need to understand their contributions to access, quality, and value,” they wrote.
The researchers had no financial conflicts to disclose.

based on data from a review of approximately 90% of physician practices in the United States.
The employment of advanced practice clinicians in primary care continues to grow, but their presence in specialty practices has not been well studied, wrote Grant R. Martsolf, PhD, of the University of Pittsburgh, and his colleagues. In a study published in JAMA Internal Medicine, the researchers used the proprietary SK&A data set to examine employment in specialty practices between 2008 and 2016.
