Treating insulin resistance may improve treatment-resistant bipolar depression, early research suggests.

In a randomized, placebo-controlled trial, treatment with the diabetes drug metformin reversed insulin resistance in 50% of patients, and this reversal was associated with significant improvement of depressive symptoms. One patient randomly assigned to placebo also achieved a reversal of insulin resistance and improved depressive symptoms.

“The study needs replication, but this early clinical trial suggests that the mitigation of insulin resistance by metformin significantly improves depressive symptoms in a significant percentage of treatment resistant bipolar patients,” presenting author Jessica M. Gannon, MD, University of Pittsburgh Medical Center (UPMC), said in an interview.

“It looks like in treatment-resistant bipolar depression, treating insulin resistance is a way to get people well again, to get out of their depression,” principal investigator Cynthia Calkin, MD, Dalhousie University, Halifax, N.S., added.

The findings were presented at the virtual American Society of Clinical Psychopharmacology 2021 Annual Meeting.
 

Chronic inflammation

The study was a joint effort by UPMC and Dalhousie University and was sponsored by the Stanley Medical Research Institute.

Patients with bipolar disorder (BD) who are obese tend to have more serious illness, with a more chronic course, more rapid cycling, and more morbidity. These patients also fail to respond to lithium, Dr. Calkin said.

“Untreated hyperinsulinemia could be contributing to a state of chronic inflammation and be involved in disease progression. So the question for me was, if we treat this insulin resistance, would patients get better?” she said.

Dr. Calkin said investigators used metformin because it is already used by psychiatrists for weight management in patients on antipsychotics.

“I wanted to test the drug that would work to reverse insulin resistance and that psychiatrists would be comfortable prescribing,” she said.

The 26-week study randomly assigned 20 patients to receive metformin and 25 patients to placebo.

All participants were 18 years and older, had a diagnosis of BD I or II, and had nonremitting BD defined by moderate depressive symptoms as measured on the Montgomery-Asberg Depression Rating Scale (MADRS) score of 15 or greater, despite being on optimal, guideline-compatible treatment.

All patients were stable, were on optimal doses of mood-stabilizing medications for at least 4 weeks prior to study entry, and had insulin resistance as defined by a Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) ≥1.8.

Characteristics were similar between the two groups, including baseline MADRS scores, body mass index, fasting glucose and insulin serum levels.

Patients were titrated up to 2,000 mg of metformin, which was the full dose, over 2 weeks and then maintained on treatment for a further 24 weeks.
 

Highly resistant population

The study’s primary outcome measure was change in MADRS score, with a response defined as a 30% reduction in MADRS from baseline.

By week 14, 10 metformin-treated patients (50%) and one patient in the placebo group (4%) no longer met insulin resistance criteria.

“It was a bit of a surprise to me that 50% of patients converted to being insulin sensitive again. When you use metformin to treat diabetes, people respond to it at more than a 50% rate, so I was expecting more people to respond,” Dr. Calkin said.

Nevertheless, the 11 patients who did respond and reversed insulin resistance achieved greater reduction in MADRS scores compared with nonconverters.

“Those who reversed their insulin resistance showed a remarkable resolution in their depressive symptoms. The reduction in MADRS scores began at week six, and were maintained through to the end of the study, and the Cohen’s d effect size for MADRS depression scores for converters was 0.52 at week 14 and 0.55 at week 26,” Dr. Calkin said.

“They were moderately to severely depressed going in, and at the end of the study, they had mild residual depressive symptoms, or they were completely well. These were very treatment-resistant patients.”

“All had failed, on average, eight or nine trials in their lifetime. When they came to us, nothing else would work. That’s one of the remarkable things about our results, just how well they responded when they had not responded to any other psychotropic medications. This approach may be very helpful for some patients,” Dr. Calkin said.
 

A holistic approach

Commenting on the study, Michael E. Thase, MD, professor of psychiatry, University of Pennsylvania, Philadelphia, said the findings need to be replicated but provide further support for the broader strategy of taking a holistic approach to the care of patients with difficult-to-treat mood disorders.

“Approximately one-half of people with treatment-resistant bipolar depression showed evidence of glucose resistance, and that adjunctive treatment with metformin, a medication that enhances insulin sensitivity, was moderately effective in normalizing glucose metabolism, with about a 50% response rate. Among those who experienced improved glucose regulation, there was a significant reduction in depressive symptoms,” he noted.

The study was funded by the Stanley Medical Research Institute (SMRI). Dr. Calkin and Dr. Thase have disclosed no relevant financial relationships.

A prebiotic therapy in development significantly reduced the number of days per month that people with gastroesophageal reflux disease (GERD) experienced heartburn.

The prebiotic treatment, maltosyl-isomalto-oligosaccharides (MIMO, ISOT-101), under development by ISOThrive, was also associated with reduced symptom severity and improved quality of life, John Selling, MD, chief medical officer at ISOThrive, said during the presentation of his study at the virtual Digestive Disease Week (DDW) 2021.

ISOT-101 is a nondigestible, nonabsorbable prebiotic carbohydrate produced by bacterial fermentation of sucrose and maltose. It was “possibly a staple of the bacterial diet that was present in the human diet during the past 10,000 years,” Dr. Selling said. He is a clinical associate professor of medicine and gastroenterology at Stanford (Calif.) University.

The prebiotic, however, “has been absent in our diet for about 50 to 100 years, driven by changes in agriculture, food production, food preservation, and dietary preferences,” he added.

Acid suppression treatments, such as proton pump inhibitors (PPIs), have long been a staple of treating GERD. However, about 40% of people taking PPIs still have symptoms, Dr. Selling said. He noted that there are concerns about the health risks associated with long-term PPI use.

A prebiotic could work because the distal esophageal microbiome in people with GERD “differs greatly” from that of healthy persons, Dr. Selling said. The prebiotic could help reduce an abnormal increase in gram-negative bacteria in these patients, for example. These bacterial strains express lipopolysaccharides on their outer cell membranes, which, in turn, alter cytokine signaling. This mechanism could lead to the hyperinflammatory state associated with GERD.

Dr. Selling and colleagues hypothesized that this treatment could help resolve GERD symptoms in two ways. The prebiotic could selectively feed the beneficial gram-positive bacteria in the distal esophagus, thereby helping to restore a healthy balance of bacteria. ISOT-101 could also produce bacteriocins that help kill the harmful gram-negative bacteria and control inflammation.

To assess the efficacy and tolerability of ISOT-101, Dr. Selling and colleagues plan to evaluate use of the agent in 110 people with GERD. The data presented at this year’s DDW are based on the first 44 participants to complete the study protocol.

Participants had to have active symptoms four or more days a week. They verbally reported symptoms to investigators and completed a daily ReQuest validated GERD symptom questionnaire.

After a week of baseline screening, participants consumed about a quarter teaspoon of ISOT-101 as the last substance swallowed before bed every night. The investigators asked participants to rate their GI symptoms, general well-being including any sleep disturbances, and quality of life on the Short Form 36 (SF-36) health survey. Participants also recorded use of any other medications during the 4-week study.

“I thought this was a very interesting study, as it proposes an alternative approach to manage patients with GERD,” Richa Shukla, MD, who was not affiliated with the research, said in an interview when asked to comment. “We see many patients with typical GERD symptoms who do not respond to PPI therapy, and perhaps considering an alternative cause and treatment may help with these patients.”

Dr. Shukla shared a couple of caveats. “This is a relatively small study, and it has not yet completed its enrollment target, so it will be helpful to see what the results are with the full study.” Also, it would be useful to know how many participants also took a PPI during the study, she said.

“Essentially, a lot remains unknown, but the study holds promise for patients,” added Dr. Shukla, assistant professor in the section of gastroenterology and hepatology at Baylor College of Medicine, Houston. “I think there is a lot of interest in the microbiome and how modulating it can impact inflammatory conditions.”
 

Key findings

The increase in heartburn-free days translated to more than eight additional days a month in which patients had no complaints of acid or heartburn. The difference from baseline was statistically significant (P < .001).

About two-thirds (66%) of participants were classified as “strong responders” to treatment, meaning they experienced an improvement of >50% in their ReQuest symptom scores over the 4 weeks. Again, the difference compared to baseline was statistically significant (P < .001).

The researchers also reported statistically significant improvements in quality-of-life indicators, such as well-being and sleep (P < .001).

The primary endpoint of the study was tolerability. The prebiotic was defined as tolerable if the ReQuest symptom scores and SF-36 scores remained constant or improved by the fourth week. ReQuest symptom scores improved for 89% of participants.

Two participants experienced nausea. No other adverse events related to ISOT-101 were reported. For five participants, ReQuest GI subscores worsened over time. For four participants, ReQuest total symptom scores worsened over time; that score represents a sum of GI and general well-being scores.
 

Unanswered questions

Inflammation in GERD is likely due to bacterial dysbiosis and acid-induced injury, Dr. Selling said.

If development of the prebiotic continues successfully, it could represent a paradigm shift in this clinical area, he said. “It suggests moving from acid reduction to also reducing dysbiosis as a treatment modality.”

But it remains unclear whether ISOT-101 would be indicated as monotherapy or for use in combination with other therapies for GERD.

Another unanswered question is whether the agent could be used to treat progressive disease. “This type of bacterial dysbiosis remains throughout the disease progression, from GERD to Barrett’s esophagus to esophageal adenocarcinoma,” Dr. Selling said.

The investigators reported that further controlled studies are forthcoming.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) has included more drugs and data and is moving toward a slightly more stepped approach to treating some forms of psoriatic disease in the latest iteration of their recommendations.

“There’s been an explosion over the last few years in terms of the number of medications,” available to treat psoriasis and psoriatic arthritis, Laura C. Coates, MBChB, PhD, said in an interview ahead of presenting the draft recommendations at the annual European Congress of Rheumatology.

“The good thing about having more drugs is you’ve got more choice, but actually it makes these recommendations even more important because it becomes more complicated to choose optimal treatment for individuals,” added Dr. Coates, a senior clinical research fellow at the University of Oxford (England).

“We’ve been waiting for a while now for the new GRAPPA recommendations,” Laure Gossec, MD, PhD, of Sorbonne University and Pitié-Salpêtrière Hospital in Paris, said in a separate interview.

New overarching principle and position statements

The goal of the recommendations hasn’t really changed since the first iteration of the guidelines in 2009, Dr. Coates noted in her presentation. They are intended to provide clinicians with recommendations “based on the best available evidence” for the management of patients with psoriatic disease.

To that end, a through process was followed, starting with the setting of PICO (Patient/population/problem; intervention; comparison; outcome) questions followed by systematic literature searches, data extraction, and review that assess the quality of evidence and then grade it accordingly before using it to inform the recommendation statements.

There is a new overarching principle that says: “These recommendations, which include the most current data concerning the optimal assessment of and therapeutic approached to psoriatic arthritis, present contextual considerations to empower shared decision making.”

The other overarching principles remain the same as in the 2015 version, with “minor wording changes particularly around the comorbidities overarching principle,” Dr. Coates said.

Also new are two position statements. “One of them is specifically around biosimilars, because that’s been a big shift since 2015,” Dr. Coates said. “It has basic rules about what evidence there should be, what we should consider when we’re using them, and patient involvement and decision making.”

The second statement covers “similar advice on tapering or discontinuing therapy – what we do when people are doing really well, how we should stop or taper, and which drugs we should choose to stop along with shared decision making with patients.”

GRAPPA intentionally gives clinicians more freedom

While there may be data to show differences in efficacy and side effects between the various drugs cited in the recommendations, “GRAPPA makes the choice to not prioritize one drug over another,” Dr. Gossec said. This decision gives “a lot of freedom then to the physician to make the decision.”

One important change according to Dr. Gossec is that oral “NSAIDs have clearly been put back as first-line treatment, before going on to disease-modifying drugs for most of the musculoskeletal manifestations. She added that for skin manifestations, topical NSAIDs were recommended, but that NSAIDs were more recommended for IBD and uveitis of course.

“I feel that’s a big step towards more of a step-up approach,” Dr. Gossec said. “The old recommendations were not clear that you would precede an NSAID before moving on to a disease-modifying drug. So, I think that makes it a little bit more similar to the 2019 EULAR recommendations.” The use of csDMARDs such as methotrexate has also been “pushed up a notch” in peripheral arthritis, she said.

What’s next?

There are a few fine tunings still to be made before the final recommendations are published. They also have to be discussed at the meeting of the GRAPPA task force, which consists of rheumatologists, dermatologists, and patient representatives.

Besides the recommendations manuscript, there will be individual papers detailing the evidence underpinning the recommendations in each of the eight domains, Dr. Coates noted. Those “will look at relative efficacy in detail,” she said. “There will be a lot more discussion/evidence summary included” to help with drug selection.

“We also plan to have some case studies to illustrate how the recommendations can be used, similar to that included in the 2015 recommendations,” she added.

Paul Studenic, MD, PhD, of the Karolinska Institute in Stockholm and Medical University of Vienna, tweeted that the GRAPPA recommendations showed treatment “needs to be tailored to the patient” taking “comorbidities as well as the heterogeneity of features of the clinical presentation into account.”

He said in an interview: “The third edition of the GRAPPA is a huge collaborative effort.” The new overarching principle put the recommendations in the context of shared decision making and, he added, they emphasize an “integrated management plan taking not only ‘classical’-related manifestations like uveitis into account but [also] a spectrum of comorbidities and reproductive health.”

GRAPPA is a not-for-profit organization and receives funding from multiple pharmaceutical companies. Currently this includes AbbVie, Amgen, Bristol-Myers Squibb, Boehringer Ingelheim, Janssen, Eli Lilly, Novartis, Pfizer, UCB, and Sun Pharma with Galapagos and Nordic Bioscience as Innovation Partners. Dr. Coates acknowledged receiving research funding, honoraria, speaker fees or all of these from most of the aforementioned companies.

Dr. Gossec has received research funding or other support from numerous pharmaceutical companies and is a member of GRAPPA and the task force that developed the EULAR guidelines on the pharmacological management of psoriatic arthritis.

Dr. Studenic had nothing to disclose.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) has included more drugs and data and is moving toward a slightly more stepped approach to treating some forms of psoriatic disease in the latest iteration of their recommendations.

“There’s been an explosion over the last few years in terms of the number of medications,” available to treat psoriasis and psoriatic arthritis, Laura C. Coates, MBChB, PhD, said in an interview ahead of presenting the draft recommendations at the annual European Congress of Rheumatology.

“The good thing about having more drugs is you’ve got more choice, but actually it makes these recommendations even more important because it becomes more complicated to choose optimal treatment for individuals,” added Dr. Coates, a senior clinical research fellow at the University of Oxford (England).

“We’ve been waiting for a while now for the new GRAPPA recommendations,” Laure Gossec, MD, PhD, of Sorbonne University and Pitié-Salpêtrière Hospital in Paris, said in a separate interview.

New overarching principle and position statements

The goal of the recommendations hasn’t really changed since the first iteration of the guidelines in 2009, Dr. Coates noted in her presentation. They are intended to provide clinicians with recommendations “based on the best available evidence” for the management of patients with psoriatic disease.

To that end, a through process was followed, starting with the setting of PICO (Patient/population/problem; intervention; comparison; outcome) questions followed by systematic literature searches, data extraction, and review that assess the quality of evidence and then grade it accordingly before using it to inform the recommendation statements.

Almost 50% of patients with migraine hesitate to seek appropriate care, new research shows. A survey of nearly 18,000 participants with migraine showed that 46% were reluctant to consult a physician about their condition. Among those who hesitated, 58% ultimately consulted a physician, but 42% did not.

Common reasons for failure to seek treatment included believing that migraine was not severe enough to warrant a consultation, worries about cost and health insurance, and concern that the health care professional would not take the disorder seriously.

This is the first study to query patients with migraine regarding whether and why they have hesitated to seek care, said coinvestigator Robert E. Shapiro, MD, PhD, professor of neurologic sciences and director of the division of headache medicine at the University of Vermont, Burlington. “Previous studies have noted differences in care seeking by demographic or other distinguishing characteristics but have not asked people with migraine whether they actually intended to seek or not seek such care,” he said.

Dr. Shapiro presented the findings at the American Headache Society’s 2021 annual meeting.
 

Delays prevent diagnosis and care

For patients with migraine, hesitating to consult a physician causes delays in, and sometimes prevents, receiving a diagnosis and appropriate care.

To assess the proportion of patients who hesitate to seek a consultation for migraine care, as well as reasons for doing so, the investigators examined data from the Observational Survey of the Epidemiology, Treatment, and Care of Migraine (OVERCOME) study. OVERCOME incorporated a prospective web-based survey that was administered to a representative sample of 41,925 individuals in the United States.

Eligible participants who completed the study’s baseline assessment had had at least one migraine attack in the previous year and either met criteria for migraine on the basis of a validated diagnostic screen or provided a self-report of a migraine diagnosis by a health care practitioner. In all, 39,494 participants reported whether they had hesitated to seek a consultation from a physician for migraine care. Of these, 17,951 were included in the analysis.

Among the 46% who hesitated to seek care, 58% ultimately sought migraine care, and 42% did not.

The investigators also examined sociodemographic characteristics and migraine-related data, including the number of monthly headache days and information regarding nausea, photophobia, and phonophobia.

Patient-reported outcomes included days with migraine-related disability during the past 3 months, treatment optimization, and the degree to which migraine limited regular activities. Investigators also examined participants’ health care use in the previous 12 months and reasons for hesitating to seek migraine care.
 

Reasons for hesitancy

A total of 17,920 participants provided reasons for hesitating to seek a migraine consultation. These included a desire to take care of migraine attacks on one’s own (45%), the belief that migraine would not be taken seriously (35%), the belief that the migraine attacks were not serious or painful enough (29%), inability to afford or unwillingness to spend money on care (29%), lack of or inadequate health insurance (21%), and fear of receiving a serious diagnosis (19%).

Reasons for hesitation differed between participants who ultimately sought a consultation with a physician and those who did not. Those who did not receive a consultation (n = 7,495) were more likely to want to take care of the migraine attacks on their own (48% vs. 43%) and to believe the attacks were not serious or painful enough (36% vs. 25%).

Participants who hesitated but later sought a consultation were more likely to report concerns that migraine would not be taken seriously (38% vs. 31%) and fear of receiving a serious diagnosis (22% vs. 15%).

Among those who did not seek a consultation versus those who did, a significantly higher proportion were women (76% vs. 73%; P < .001).

“This is an interesting finding, since prior studies have indicated that, overall, women with migraine are more likely to have consulted a doctor for it – and also more likely to have been diagnosed with it,” Dr. Shapiro said.

On the other hand, women were 30% more likely to visit emergency departments or urgent care clinics for migraine care than men, he noted.

“These findings suggest some women may be experiencing particular barriers to receiving successful consultation care and that they may persistently hesitate to seek it,” said Dr. Shapiro. He noted that these barriers might be financial or attitudinal.

“Women are reported to be less likely to receive treatment for pain conditions, and furthermore, stigma toward migraine in particular may limit its perceived seriousness,” he said.
 

‘Equitable access’ needed

Those with full-time employment were significantly more likely to seek a migraine consultation than were those who were not employed full time (46% vs. 42%; P < .001). Patients who sought care were more likely to have health insurance (87% vs. 78%; P < .001).

Having health insurance (odds ratio [OR], 1.99), having previously received a migraine diagnosis (OR, 2.71), and degree of disability (severe vs. none: OR, 2.76; moderate vs. none: OR, 2.04) were associated with increased likelihood of seeking a migraine consultation among those who initially hesitated. Other factors included being male (OR, 1.49), having nausea (OR, 1.15), or being employed full time (OR, 1.24).

“Taken together, our findings suggest consultation rates may be limited by financial barriers and pervasive attitudes that migraine is either not serious or is untreatable,” said Dr. Shapiro. Consistent with this hypothesis is the finding that individuals with migraine who had received an appropriate diagnosis and were therefore better informed about the condition were more likely to continue to seek care for it, he noted.

Because most outpatient medical encounters for migraine are with primary care practitioners, it may make sense to ensure that such clinicians are “well trained in diagnosing and treating common presentations of migraine,” Dr. Shapiro said. It is equally important to ensure “equitable access to health insurance to pay for these consultations,” he added.
 

‘Take migraine more seriously’

Commenting on the findings, Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, said the study was well designed.

Potential weaknesses include the fact that patients were required only to have one migraine attack per year and that not all were diagnosed by a headache specialist using ICHD-3 criteria.

Still, “online, validated, patient-reported data is quite acceptable,” said Dr. Rapoport, who was not involved in the research.

He noted that there is a clear message from the findings for all physicians who see patients with headache disorders: “You will increase the chance of patients consulting and continuing to consult when you make an accurate migraine diagnosis, take migraine more seriously, and understand the stigmas attached to it – and when there are reduced institutional barriers and costs of health care.”

The findings suggest that neurologists should strive to provide patients with ongoing care and medication, he added. In addition, there is a need for further education about the stigma associated with migraine and about how others view this disabling disease, Dr. Rapoport concluded.

The study was funded by Eli Lilly. Dr. Shapiro has consulted for Eli Lilly and Lundbeck. Dr. Rapoport has reported no relevant financial relationships.

It is equally important to ensure “equitable access to health insurance to pay for these consultations,” he added.
 

‘Take migraine more seriously’

Commenting on the findings, Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, said the study was well designed.

Potential weaknesses include the fact that patients were required only to have one migraine attack per year and that not all were diagnosed by a headache specialist using ICHD-3 criteria.

Still, “online, validated, patient-reported data is quite acceptable,” said Dr. Rapoport, who was not involved in the research.

He noted that there is a clear message from the findings for all physicians who see patients with headache disorders: “You will increase the chance of patients consulting and continuing to consult when you make an accurate migraine diagnosis, take migraine more seriously, and understand the stigmas attached to it – and when there are reduced institutional barriers and costs of health care.”

The findings suggest that neurologists should strive to provide patients with ongoing care and medication, he added. In addition, there is a need for further education about the stigma associated with migraine and about how others view this disabling disease, Dr. Rapoport concluded.

The study was funded by Eli Lilly. Dr. Shapiro has consulted for Eli Lilly and Lundbeck. Dr. Rapoport has reported no relevant financial relationships.

For patients with HER2-negative metastatic breast cancer, first line chemotherapy with cabazitaxel (Jevtana) every 3 weeks offers efficacy comparable to that of once-weekly paclitaxel, but with lower risk for peripheral neuropathy and better patient-reported quality of life, investigators in the multicenter CONCERT trial found.

In an open-label clinical trial of 158 patients from 14 hospitals in the United Kingdom, there was no difference in the primary endpoint of progression-free survival (PFS) or a secondary overall survival endpoint between patients randomly assigned to initial chemotherapy with cabazitaxel every 3 weeks or weekly paclitaxel, reported Amit Bahl, MD, of University Hospital Bristol, England, and colleagues.

“Cabazitaxel is safe and well tolerated for metastatic breast cancer and requires fewer hospital visits than weekly paclitaxel, which is very important for patients and health care providers, but more so in the current situation,” he said in an oral abstract session at the American Society of Clinical Oncology annual meeting (Abstract 1008).

Cabazitaxel is currently approved in the United States and Europe in combination with prednisone for treatment of patients with metastatic castration-resistant prostate cancer previously treated with a docetaxel-containing treatment regimen. It is not currently approved for the treatment of metastatic breast cancer, but has been explored for this indication in clinical trials.

“In the metastatic setting, where patients continue on treatment pretty much indefinitely until disease progression or unacceptable toxicity, the use of an every-3-week regimen could be attractive, because it means less visits for the patients, and it appears that this drug has lower toxicity in terms of peripheral neuropathy,” said breast cancer specialist Aditya Bardia, MD, MPH, who was not involved in the study.

Dr. Bardia, of Mass General Cancer Center in Boston, commented on the study in an interview.

Although paclitaxel is commonly used as first-line chemotherapy for HER2-negative metastatic breast cancer, it is associated with only modest response rates, ranging from 21.5% to 53.7% and carries significant risk of peripheral neuropathy, Dr. Bahl and colleagues noted.

“There is an unmet need for an alternative first-line cytotoxic chemotherapy agent, and cabazitaxel is a taxoid agent which has showed promising results in phase 2 trial of metastatic breast cancer patients in the second-line setting, even those with taxane resistance,” he said.
 

Open-label trial

To see whether cabazitaxel could meet those requirements, the investigators conducted a phase 2 randomized trial in which patients with HER2-negative metastatic breast cancer not previously treated with cytotoxic chemotherapy were assigned, 79 in each arm, to receive cabazitaxel 25 mg/m² every 3 weeks, or paclitaxel 80 mg/m² weekly.

The median patient age was 56 years in the cabazitaxel group and 61 years in the paclitaxel group. Roughly two-thirds of patients in each arm had Eastern Cooperative Oncology Group performance status 0, and the remainder had ECOG performance status 1.

In each arm, the median time on treatment was 15 weeks, but treatment delays and dose reductions were more common among patients on paclitaxel than cabazitaxel (61% vs. 39%, and 37% vs. 24%, respectively).

There were 149 PFS events at the time of the analysis. The median PFS with cabazitaxel was 6.7 months vs. 5.8 months with paclitaxel. This difference was not statistically significant. Median overall survival was 20.6 months in the cabazitaxel arm, vs. 18.2 months 20.0 months, respectively.

Similarly, there were no significant differences in either the overall response rates (42% vs. 37%), or time to response.

There were no complete responses with cabazitaxel vs. two (2.5%) with paclitaxel. The respective partial response rates were 41.8% vs. 34.2%.

In a subgroup analysis of PFS, there were no significant between-arm differences, except for an improved PFS in patients 65 and older with cabazitaxel (hazard ratio 0.45, 95% confidence interval, 0.25-0.80).
 

Quality of life favors cabazitaxel

Grade 3 or greater adverse events occurred in 42% of patients on cabazitaxel vs. 51% on paclitaxel. Diarrhea, febrile neutropenia, and nausea were the most common grade 3 or greater events in the cabazitaxel arm, whereas grade 3 or greater lung infection and peripheral neuropathy were more common with paclitaxel.

Sensory peripheral neuropathy of any grade occurred in 16% of patients assigned to cabazitaxel, compared with 54% assigned to paclitaxel. The respective rates of alopecia were 27% and 42%.

Over the course of treatment, the mean EuroQuol EQ-5D-5L single index utility score and visual analogue scale score were higher with cabazitaxel arm compared to paclitaxel, suggesting better patient quality of life with cabazitaxel.

In addition, throughout treatment patients in the cabazitaxel arm reported significantly better scores on The Functional Assessment of Cancer Therapy – Breast (FACT-B) breast cancer subscale, Dr. Bahl said.
 

Second-line may be better

ASCO invited discussant Marleen Kok, MD, PhD, from the Netherlands Cancer Institute in Amsterdam, pointed out that in the phase 2 GENEVIEVE trial comparing the efficacy and safety of cabazitaxel versus weekly paclitaxel as neoadjuvant treatment in patients with triple negative or luminal B/HER2 normal breast cancer the pathologic complete response rate with cabazitaxel was 1.2%, compared with 11% with paclitaxel.

“This GENEVIEVE trial, together with the CONCERT trial, suggests that there is not a big role for cabazitaxel to be used upfront before other taxanes,” she said.

However, in a phase 2 study of cabazitaxel as second-line therapy in patients with HER2-negative metastatic breast cancer who had previously been treated with taxanes, the overall response rate was 23%, “which is still of interest and importance for our patients,” she added.

Dr. Kok did not address quality of life differences between the regimens, however.

In a side note, Dr. Bardia said that “if there were an oral form of paclitaxel, that would certainly be very welcome, in that an oral drug is more convenient for patients, and would require fewer visits to the hospital.”

The CONCERT trial was funded by an investigator-sponsored study grant from Sanofi. Dr. Bahl disclosed honoraria and institutional research funding from Sanofi/Aventis and others, and travel expenses from Bayer and Roche. Dr. Kok disclosed a consulting or advisory role for Bristol Myers Squibb/Medarex, and institutional research funding from that company and others.

Patients overwhelmingly found telemedicine care for headache a satisfactory and beneficial experience during the COVID-19 pandemic, according to a study presented at the American Headache Society’s 2021 annual meeting. Most patients who used telemedicine said they would like to continue using it after the pandemic, though the study also revealed barriers to care for a small percentage of respondents.

“Telemedicine minimizes the physical and geographic barriers to health care, preserves personal protective equipment, and prevents the spread of COVID-19 by allowing encounters to happen in a socially distanced way,” said Chia-Chun Chiang, MD, assistant professor of neurology at Mayo Clinic in Rochester, Minn. “Telemedicine provides patients with opportunities to gain better control of their headache disorders while not having to commit to the time to travel and risk of exposure to COVID-19.” If insurance coverage for virtual care were rolled back, “patients and multiple levels of health care providers would be significantly affected,” she said.

The research relied on findings from a 15-question survey distributed by the nonprofit American Migraine Foundation through email and social media to more than 100,000 people. Among the 1,172 patients who responded to the survey, 1,098 had complete responses, and 86.6% were female.

The vast majority of these patients (93.8%) had had a previous diagnosis of a headache. Just over half (57.5%) said they used telemedicine during the study period, with most of those visits (85.5%) being follow-up care and 14.5% involving a new patient visit.

Among those who did not use telemedicine, most (56.1%) said they didn’t need a visit. However, a quarter of these respondents (25.2%) said they didn’t know telemedicine was an option, and 12.9% said they would have preferred telemedicine but it wasn’t offered by their doctors. A smaller proportion (3.5%) said they wanted to use virtual care but that their insurance did not cover it, and nearly as many (2.2%) said they wanted telemedicine but didn’t have the technology needed to use it.

“The COVID-19 pandemic has highlighted that reliable Internet service has contributed to disparities in access in many ways, including health care via telemedicine,” Dr. Chiang said. “Those who are not able to afford Internet, lack proficiency in the use of technology, or have cognitive impairment might not be able to utilize telemedicine.”

Among those who did receive telemedicine care for headache, about a third (34.4%) received care from a general neurologist while 43.7% saw a headache specialist and nearly a third (30.7%) saw a primary care provider. The remaining visits included 11.3% who saw headache nurse practitioners and 3.2% who saw headache nurses.

Most patients did not have a new or changed diagnosis at their visit; only 7.4% received a new headache diagnosis during their telemedicine appointment. Though 43.7% had no change to their therapy, a little more than half of patients (52.4%) received a new treatment, a finding that caught the interest of Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, and past president of the International Headache Society.

“The techniques used [in virtual visits] were good enough for the caregiver to make critical decisions about how the patient was doing and what new treatment might be better for them,” said Dr. Rapoport, who was not involved in the research. “I believe that most headache specialists will gradually resume in office visits,” he said, but “this study shows it would be okay for some or most of the revisits to continue to be done virtually.”

The vast majority of patients rated their care as “very good” (62.1%) or “good” (20.7%). Less satisfied responses included 10.5% who felt their experience was “fair,” 3.6% who said it was “poor,” and 3.1% who gave other responses.

These results fit with the experience of Dr. Rapoport and of Paul B. Rizzoli, MD, associate professor of neurology at Harvard Medical School and clinical director of the John R. Graham Headache Center at Brigham and Women’s Faulkner Hospital, both in Boston.

“Telemedicine worked better than we anticipated,” said Dr. Rizzoli when asked for comment. “I was especially surprised how comfortable I became with its use for many, but not all, new patients. While I don’t expect it to replace in-person visits, I do expect that it will and should be a permanent part of our care going forward, especially for follow-up visits.”

The findings supported that expectation as well: An overwhelming majority of those who responded to the survey (89.8%) also said they would like to keep receiving telemedicine care for their headache care and treatment. This percentage was split evenly between those who said they would like to always receive care virtually and those who would only want to use it for some appointments. A smaller proportion said they did not want to keep using virtual care (7.1%) or weren’t sure (3.1%).

“Telemedicine has become an essential tool for patients and a wide variety of clinicians,” Dr. Chiang reported during her presentation. “Telemedicine facilitated headache care for many patients during the COVID-19 pandemic, resulting in high patient satisfaction rates and a desire to continue to utilize telemedicine for future headache care for those who responded to the online survey.”

Dr. Rapoport noted that a particular benefit of telemedicine in his practice is avoiding transportation issues.

“In Santa Monica and Los Angeles, my patients coming from 10 or more miles away usually have to contend with difficult traffic, which created stress and often made them late and upset the office schedule,” Dr. Rapoport said. “I found that virtual visits were almost always shorter, on time, and were as effective for the patient as an in-person visit.”

Dr. Chiang drew attention, however, to the barriers to care found in the study, including not having or knowing of telemedicine as an option, and not having access to the technology or insurance coverage needed to take advantage of it. She listed three ways to address those challenges and increase health care accessibility to patients:
 

• Expand insurance coverage to reimburse telemedicine even after the pandemic.
• Widely promote and broadcast the use of virtual care.
• Make Internet access a priority as a necessity in society and expand access.

Dr. Rizzoli also noted some ways to improve telemedicine. “We could easily develop improved means of delivering vital signs and other bio-information over telemedicine to improve decision-making,” he said. “A difficult task going forward will be to fix legal questions associated with virtual visits across state lines which, especially in the small New England states, come up frequently and are currently illegal.”

Dr. Rapoport noted ways that patients can facilitate effective telemedicine visits. “Doctors should insist that patients keep careful records of their headaches, triggers, medicines, etc., either on paper or preferably via an app on their smartphones, which is usually always accessible,” Dr. Rapoport said. “With good data and a good electronic connection, the visit should go well.”

Among the study’s limitations were a comparatively small response rate (1.11% of those invited to participate) and ascertainment bias.

“The take-home message from the experience is that this turns out to be an effective, efficient and accepted means of delivering care that should be developed further,” Dr. Rizzoli said.

No external funding was noted. Dr. Chiang and Dr. Rizzoli had no disclosures. Dr. Rapoport has advised AbbVie, Amgen, Biohaven, Cala Health, Satsuma, Teva Pharmaceutical Industries, Theranica, Xoc and Zosano, and is on the speakers bureau of AbbVie, Amgen, Biohaven, Lundbeck and Teva Pharmaceutical Industries.

“In Santa Monica and Los Angeles, my patients coming from 10 or more miles away usually have to contend with difficult traffic, which created stress and often made them late and upset the office schedule,” Dr. Rapoport said. “I found that virtual visits were almost always shorter, on time, and were as effective for the patient as an in-person visit.”

Dr. Chiang drew attention, however, to the barriers to care found in the study, including not having or knowing of telemedicine as an option, and not having access to the technology or insurance coverage needed to take advantage of it. She listed three ways to address those challenges and increase health care accessibility to patients:
 

• Expand insurance coverage to reimburse telemedicine even after the pandemic.
• Widely promote and broadcast the use of virtual care.
• Make Internet access a priority as a necessity in society and expand access.

Dr. Rizzoli also noted some ways to improve telemedicine. “We could easily develop improved means of delivering vital signs and other bio-information over telemedicine to improve decision-making,” he said. “A difficult task going forward will be to fix legal questions associated with virtual visits across state lines which, especially in the small New England states, come up frequently and are currently illegal.”

Dr. Rapoport noted ways that patients can facilitate effective telemedicine visits. “Doctors should insist that patients keep careful records of their headaches, triggers, medicines, etc., either on paper or preferably via an app on their smartphones, which is usually always accessible,” Dr. Rapoport said. “With good data and a good electronic connection, the visit should go well.”

Among the study’s limitations were a comparatively small response rate (1.11% of those invited to participate) and ascertainment bias.

“The take-home message from the experience is that this turns out to be an effective, efficient and accepted means of delivering care that should be developed further,” Dr. Rizzoli said.

No external funding was noted. Dr. Chiang and Dr. Rizzoli had no disclosures.

Patients overwhelmingly found telemedicine care for headache a satisfactory and beneficial experience during the COVID-19 pandemic, according to a study presented at the American Headache Society’s 2021 annual meeting. Most patients who used telemedicine said they would like to continue using it after the pandemic, though the study also revealed barriers to care for a small percentage of respondents.

“Telemedicine minimizes the physical and geographic barriers to health care, preserves personal protective equipment, and prevents the spread of COVID-19 by allowing encounters to happen in a socially distanced way,” said Chia-Chun Chiang, MD, assistant professor of neurology at Mayo Clinic in Rochester, Minn. “Telemedicine provides patients with opportunities to gain better control of their headache disorders while not having to commit to the time to travel and risk of exposure to COVID-19.” If insurance coverage for virtual care were rolled back, “patients and multiple levels of health care providers would be significantly affected,” she said.

The research relied on findings from a 15-question survey distributed by the nonprofit American Migraine Foundation through email and social media to more than 100,000 people. Among the 1,172 patients who responded to the survey, 1,098 had complete responses, and 86.6% were female.

The vast majority of these patients (93.8%) had had a previous diagnosis of a headache. Just over half (57.5%) said they used telemedicine during the study period, with most of those visits (85.5%) being follow-up care and 14.5% involving a new patient visit.

Among those who did not use telemedicine, most (56.1%) said they didn’t need a visit. However, a quarter of these respondents (25.2%) said they didn’t know telemedicine was an option, and 12.9% said they would have preferred telemedicine but it wasn’t offered by their doctors. A smaller proportion (3.5%) said they wanted to use virtual care but that their insurance did not cover it, and nearly as many (2.2%) said they wanted telemedicine but didn’t have the technology needed to use it.

“The COVID-19 pandemic has highlighted that reliable Internet service has contributed to disparities in access in many ways, including health care via telemedicine,” Dr. Chiang said. “Those who are not able to afford Internet, lack proficiency in the use of technology, or have cognitive impairment might not be able to utilize telemedicine.”

Among those who did receive telemedicine care for headache, about a third (34.4%) received care from a general neurologist while 43.7% saw a headache specialist and nearly a third (30.7%) saw a primary care provider. The remaining visits included 11.3% who saw headache nurse practitioners and 3.2% who saw headache nurses.

Most patients did not have a new or changed diagnosis at their visit; only 7.4% received a new headache diagnosis during their telemedicine appointment. Though 43.7% had no change to their therapy, a little more than half of patients (52.4%) received a new treatment, a finding that caught the interest of Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, and past president of the International Headache Society.

“The techniques used [in virtual visits] were good enough for the caregiver to make critical decisions about how the patient was doing and what new treatment might be better for them,” said Dr. Rapoport, who was not involved in the research. “I believe that most headache specialists will gradually resume in office visits,” he said, but “this study shows it would be okay for some or most of the revisits to continue to be done virtually.”

The vast majority of patients rated their care as “very good” (62.1%) or “good” (20.7%). Less satisfied responses included 10.5% who felt their experience was “fair,” 3.6% who said it was “poor,” and 3.1% who gave other responses.

These results fit with the experience of Dr. Rapoport and of Paul B. Rizzoli, MD, associate professor of neurology at Harvard Medical School and clinical director of the John R. Graham Headache Center at Brigham and Women’s Faulkner Hospital, both in Boston.

“Telemedicine worked better than we anticipated,” said Dr. Rizzoli when asked for comment. “I was especially surprised how comfortable I became with its use for many, but not all, new patients. While I don’t expect it to replace in-person visits, I do expect that it will and should be a permanent part of our care going forward, especially for follow-up visits.”

The findings supported that expectation as well: An overwhelming majority of those who responded to the survey (89.8%) also said they would like to keep receiving telemedicine care for their headache care and treatment. This percentage was split evenly between those who said they would like to always receive care virtually and those who would only want to use it for some appointments. A smaller proportion said they did not want to keep using virtual care (7.1%) or weren’t sure (3.1%).

A phase 2 study of the anti-calcitonin gene–related peptide (CGRP) antibody fremanezumab found no benefit of treatment in persistent posttraumatic headache. Anti-CGRP therapy had been predicted to be effective, given its history of improving other forms of headache, and preclinical studies had suggested that CGRP plays a role in late pain sensitization that can occur after mild brain injuries.

“There was a decrease in migraine headache days of moderate or severe intensity in both groups. But the difference between fremanezumab and placebo treatment was not statistically significant, either looking at that on a monthly basis or over the total 12 weeks of treatment,” Egilius L.H. Spierings, MD, PhD, said during his presentation of the results at the American Headache Society’s 2021 annual meeting. Dr. Spierings is medical director of the Boston Headache Institute.
 

Disappointing findings

“That’s sad. It’s just dreadful news,” Stewart J. Tepper, MD, professor of neurology at Geisel School of Medicine at Dartmouth, Hanover, N.H., said in an interview. Dr. Tepper was not involved in the study. The results suggest that CGRP mechanisms may not be relevant to persistent posttraumatic headache, but it could still play a role at onset. “We have to rethink this. Either it’s that chronic, persistent posttraumatic headache does not have a CGRP biology, or it’s that you have to get to them earlier [in the disease process],” he said.

The negative results were surprising, according to Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, and former president of the International Headache Society. He noted that the study was small, and the researchers were unable to conduct subgroup analyses. “Posttraumatic headaches are usually broken down into those that phenotypically look like migraine, or phenotypically look like tension-type headache. It would have been nice to know if most of them had what clinically appears to be tension-type headache, and maybe that’s why they didn’t respond. Or did most of them have a migraine phenotype, and then it would be a little more surprising that they didn’t respond,” Dr. Rapoport said in an interview.

As a result, he believes that further studies might show that fremanezumab is an effective treatment for posttraumatic headache. “I would not give up on it. I expect that a larger study with better power, and a better idea of exactly what was wrong with the patients, might end up being a positive study,” he said.

Although most posttraumatic headaches resolve within weeks or months, some can linger or become chronic for years. Pain medication is often prescribed but should not be, according to Dr. Rapoport, because it can lead to medication overuse headache that worsens the problem. “So we badly need a good temporary preventive treatment. The thought of giving our newest, most effective preventive medications, with few adverse events, is a good one. It just didn’t seem to work in this fairly small and underpowered study,” he said.
 

The phase 2 trial

The trial included 87 patients with new-onset or significant worsening of headache following a minor traumatic brain injury or concussion, who were randomized to treatment with 675 mg subcutaneous fremanezumab once monthly, or placebo. The average elapsed time since the trauma was 8.1 years in the placebo group and 9.3 years in the fremanezumab arm. The average number of moderate to severe headache days was 18.5 days in the placebo group and 18.4 days in the fremanezumab group. The initial 12-week randomized period was followed by an open-label period in which patients on placebo received the study drug.

After 12 weeks of treatment, there was a greater decrease in moderate to severe headache days in the placebo arm, though the difference was not statistically significant (–5.1 versus –3.6 days; P = .1876). At 1 month, the two groups were similar (–4 days placebo versus –3.6 days fremanezumab), but there was a greater reduction in the placebo arm at 2 months (–6.7 versus –3.7 days) and 3 months (–7.21 versus –5.2 days).

A secondary endpoint was the proportion of patients who experienced a 50% or greater reduction in moderate to severe headache days, and there was no significant difference between placebo and fremanezumab after 12 weeks (26% versus 21%) or at month 1 (26% versus 19%), month 2 (33% versus 19%), or month 3 (28% versus 33%).

Adverse events occurred more often in the placebo group (81% versus 72%), and all were mild or moderate, with the exception of one that occurred in the placebo group. There were no deaths, and no meaningful changes in laboratory or clinical examinations.

Apparent migraines experienced by 19th century factory workers remain relevant to clinical medicine today. Those workers were employed in the manufacture of nitroglycerine, and many became patients of a physician who in 1880 described them as experiencing headache with nausea, vomiting, and walking lightly on their toes. A majority of patients were women.

When researchers in the 1950s worked out how to use nitroglycerine to trigger migraine-like headaches, the chemical became an important experimental tool, Peter Goadsby, MD, PhD, said during a talk on the translational importance of nitroglycerine in headache medicine at the American Headache Society’s 2021 annual meeting.

Some neurologists view nitroglycerine with skepticism, but that’s not necessarily warranted, said Dr. Goadsby. “To me, it’s underappreciated, but it has matured. If you were talking about this topic a decade ago, then the criticism would be that somehow that it’s not migraine, or it’s got nothing really to do with migraine,” he said in an interview.

But varying lines of clinical and experimental research have strengthened the case that nitroglycerine-induced migraine is largely indistinguishable from natural-onset migraine, and that studies that use it can provide important insights into patient management. “If I said to a colleague, ‘I’ve got this patient with headaches, and they’ve got nausea, and they’re sensitive to light. And if they move their head about, it’s worse,’ that sounds like migraine, and that’s what they’d say. The patients will tell you it’s the same, and they have the same premonitory symptoms. They respond to the same medicines,” said Dr. Goadsby.

The method is also one of the few available to study premonitory symptoms, since it is difficult to predict naturally-occurring migraines. Once the minimal dose of nitroglycerine dose to trigger an attack was worked out, researchers could use functional imaging to monitor what happens before and during the episode. To support this point, Dr. Goadsby cited a 2005 study in Brain by his own group. They used positron-emission tomography (PET) scans to conclude that lateralized brain dysfunction is associated with lateralized pain during migraine.

The premonitory stage is characterized by symptoms such as neck stiffness, cognitive impairment, mood alterations, and fatigue, as well as homeostatic symptoms such as sleepiness and polyuria. Other possible symptoms include photophobia, phonophobia, nausea, and cranial autonomic symptoms. These symptoms can be studied and established with the use of nitroglycerin trigger studies.

Dr. Goadsby pointed out that triggered episodes can also be used to test therapeutics. Calcitonin gene-related peptide receptor antagonists, 5-HT1F receptor agonists, and substance P/neurokinin 1 receptor antagonists have all been tested against nitroglycerine-induced migraines.

Other studies have used repeat exposures to nitroglycerine to better understand the effects of chronic migraines. Dr. Goadsby cited an example by researchers at the University of Illinois at Chicago led by Amynah Pradhan, PhD, which administered nitroglycerine repeatedly to mice and found that it led to acute mechanical hyperalgesia and basal hyperalgesia. The latter effect was dose dependent and persistent after nitroglycerine administration stopped. The phosphodiesterase inhibitor sildenafil, which can trigger migraines in humans, made the effect worse, suggesting that nitric oxide may be the mediator.

Other studies have used repeat exposures to nitroglycerine to better understand the effects of chronic migraines. Dr. Goadsby cited an example by researchers at the University of Illinois at Chicago led by Amynah Pradhan, PhD, which administered nitroglycerine repeatedly to mice and found that it led to acute mechanical hyperalgesia and basal hyperalgesia. The latter effect was dose dependent and persistent after nitroglycerine administration stopped. The phosphodiesterase inhibitor sildenafil, which can trigger migraines in humans, made the effect worse, suggesting that nitric oxide may be the mediator.

A novel 16-gene panel based on the biology of locoregional recurrence in early invasive breast cancer can both identify patients with a low risk of recurrence if they were to skip postsurgery radiation therapy, and predict which patients would be unlikely to benefit from adjuvant radiation, investigators reported.

Among 354 patients with stage I or II invasive estrogen receptor–positive (ER+), HER2-negative breast cancers who did not receive adjuvant systemic therapy, the genomic signature, dubbed POLAR (Profile for the Omission of Local Adjuvant Radiation) was prognostic for locoregional recurrence in patients who did not undergo radiation therapy, reported Martin Sjöström, MD, PhD, of the University of California, San Francisco, and colleagues.

They reported their findings in a poster presented during the American Society of Clinical Oncology (ASCO) annual meeting (Abstract 512).

“This is to our knowledge the first radiation-omission signature that is both prognostic and predictive: prognostic for outcomes in the absence of radiation, and predictive of benefits,” coauthor Corey Speers MD, PhD, of the University of Michigan, Ann Arbor, said in an interview.

The investigators conducted a retrospective analysis of data on patients enrolled in the SweBCG 91 RT trial, in which 1,187 patients with T1-2N0M0 breast cancer underwent a standardized radical sector resection and were then randomly assigned to either postoperative radiotherapy or no further treatment.

As the investigators reported in a long-term follow-up study presented in 2010 at the San Antonio Breast Cancer Symposium, the addition of postoperative radiation did not significantly affect overall survival, but was associated with a significant improvement in recurrence-free survival.

In the study presented at ASCO 2021, Dr. Sjöström and colleagues in Sweden, the United States, and Canada sought to determine whether they could identify a genomic signature that would identify women at very low risk for recurrence who could safely be spared from radiotherapy.

They focused on those patients in the study with ER+, HER2-negative tumors who did not receive adjuvant systemic therapy. The patients were divided into a training cohort of 243, and a validation cohort of 354 patients.

The investigators performed transcriptome-wide profiling of tumors, and identified both biological gene sets and individuals genes associated with locoregional recurrence among patients in the training set who did not receive radiotherapy.

The final POLAR genomic signature, containing 16 genes, was locked prior to testing in the validation cohort.

In a multivariable Cox model adjusting for age, grade, tumor size and luminal A vs. luminal B subtype, the POLAR gene set was prognostic for locoregional recurrence, with a hazard ratio (HR) of 1.7 (P < .001).

The 10-year locoregional recurrence rate for patients in the POLAR low-risk category who had not received radiation was 7%, and there was no significant benefit for POLAR low-risk patients who did receive radiation (HR 1.1, P = ns).

In contrast, patients classified as POLAR high risk who received radiotherapy had significantly lower risk for locoregional recurrence than high-risk patients who did not receive radiotherapy (HR 0.43, P = .0053).

Dr. Speers said that the POLAR signature appears to be unique in its ability to discriminate radiation-omission risk.

“At least looking in this cohort in the Swedish trial, none of other previously derived signatures – Mammaprint, ProSigna, Oncotype – were prognostic or predictive of locoregional recurrence events with radiation,” he said.

The investigators are currently exploring the POLAR signature in other clinical trials in which patients were randomized to receive radiation or no radiation.
 

­‘A true victory’

Invited discussant Benjamin D. Smith, MD, of the University of Texas MD Anderson Cancer Center in Houston, pointed out that in randomized clinical trials, approximately 60% of patients treated for early breast cancer did not experience recurrence in the absence of radiation, and that radiation prevented recurrence in about 30%, while about 10% experienced recurrence despite receiving radiation.

He said that the study by Dr. Sjöström and colleagues asks the question “can we use molecular factors to help identify patients who will not recur with lumpectomy alone without radiation therapy?”

The 60% of patients who will not experience recurrence in the absence of radiation can be categorized into two subpopulations: those with no residual malignant clonogens – the population included in this study by Dr. Sjöström and colleagues – and those with residual clonogens in the breast or elsewhere in the body that are sensitive to adjuvant endocrine therapy.

He said that the 7% 10-year risk of recurrence among patients in the POLAR low-risk group, who had neither radiation nor endocrine therapy, “is an exceptional outcome, which should be applauded, and I would point out that this risk of local recurrence of only 7% is at least in the same ballpark as the risk of recurrence that we accept every day when we treat early stage breast cancer patients with mastectomy alone, so this is a true victory.

“When we reflect on these provocative results from Dr. Sjöström and colleagues, it prompts in mind the question, could there be a group of patients with early breast cancer for whom a true ‘one-and-done’ strategy could be effective and safe?” Dr. Smith said.

Getting there will require a multidisciplinary, multimodality approach, involving imaging features of the primary tumor, clinical and pathologic features, and molecular information such as that provided by the POLAR genomic signature, he said.

The study was supported by PFS Genomics. Dr. Sjöström reported institutional funding from PFS Genomics. Dr. Speers disclosed stock and other ownership interests in the company, and he has applied for a patent on methods and genomic classifiers for prognosis of breast cancer and predicting benefit from adjuvant radiotherapy. Dr. Smith reported an equity interest in Oncora Medical, and an uncompensated relationship with the American Society for Radiation Oncology.

For women with HER2-positive early breast cancer treated with an anthracycline-based regimen followed by trastuzumab (Herceptin), concurrent therapy with the angiotensin-converting enzyme (ACE) inhibitor lisinopril can help to prevent a decline in left-ventricular ejection fraction (LVEF) below 50%, investigators in a community-based study found.

Among 424 women with HER2-positive early-stage breast cancer, the rate of LVEF decline to below 50% was 21.4% among patients randomized to receive an anthracycline-based regimen, compared with 4.1% for patients who were treated with a non–anthracycline-based regimen.

Among patients in the anthracycline arm, treatment with lisinopril, but not carvedilol or placebo, was associated with significant protection against LVEF decline, reported Pamela N. Munster, MD, of the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco.

“The findings of this study suggested that the drop in left ventricular ejection fraction to below 50% or to below normal was much larger than previously reported in the anthracycline group,” she said in a video presentation during a poster discussion session at the American Society of Clinical Oncology annual meeting. (Abstract 509).

Although HER2 inhibition is a highly effective treatment strategy for patients with HER2-positive tumors, trastuzumab-associated decline in LVEF and clinical heart failure can result in treatment interruption or discontinuation of therapy, the authors noted.

They conducted the prospective randomized trial to see whether trastuzumab-associated cardiotoxicity could be mitigated by concurrent use of either an ACE inhibitor or beta-blocker.

They enrolled women with early HER2-positive breast cancer from 127 community-based oncology centers.

The patients were randomly assigned to receive either an anthracycline- or non–anthracycline-containing regimen, followed by a year of trastuzumab, and were then randomized again to receive either lisinopril, carvedilol, or placebo concurrently with trastuzumab.

The patients were assessed for cardiotoxicity every 12 weeks with a multiple-gated acquisition (MUGA) scan and echocardiogram. Cardiotoxicity was defined as an absolute decrease in LVEF of 10% or more, or at least 5% decrease in LVEF below 50% at baseline.
 

Small LVEF declines in all

The investigators observed that all patients in the study experienced a small but not clinically relevant decrease in LVEF during trastuzumab therapy, and that this decline was not significantly ameliorated by any of the interventions.

However, as noted before, among patients assigned to anthracycline-based regimens the rate of decline to LVEF below 50% was 21.4%, compared with 4.1 for patients assigned to non–anthracycline regimens.

LVEF declines of at least 10% occurred in 5.5% of patients who received anthracyclines, and in 14.4% of those who received a non-anthracycline regimen.

Among patients who received anthracycline, only 10.8% randomized to receive lisinopril prophylaxis experienced a decline in LVEF, compared with 30.5% assigned to placebo (P = .045).

“In contrast, while carvedilol showed a numerical prevention of LVEF below 50% to 22.8%, this was not statistically significant,” Dr. Munster said.

Decreases in LVEF of 10% or greater within the normal LVEF range were similar in both chemotherapy arms and were not affected by either lisinopril or carvedilol.

“Lisinopril was well tolerated in this group, even in patients without hypertension,” she said.

“In women treated in a community-based environment who could benefit from anthracyclines or where anthracyclines are indicated, one should anticipate the decrease in left ventricular ejection fraction to below normal to be larger than is reported by other groups. However, this could be prevented by lisinopril,” she concluded.
 

Low numbers overall

Invited discussant Fatima Cardoso, MD, of Champalimaud Clinical Center in Lisbon, noted that the overall number of cardiotoxicity events and the rate of important decreases in LVEF were comparatively low.

She also pointed out that the findings are in line with another recent analysis of the same cohort by the same authors, although in the earlier analysis the investigators found that the effect on cardiotoxicity-free survival was good with both agents compared with placebo, but slightly better with carvedilol (hazard ratio 0.49, P = .009) than with lisinopril (HR 0.53, P = .015).

“Lisinopril has the most important effect regarding preventing decrease of LVEF below 50%. When we look at the curves of LVEF drops above 10%, carvedilol seems to have a slightly bigger effect,” she said.

The trial was cosponsored by the SunCoast Community Clinical Oncology Programs Research Base at University of South Florida, Tampa, and by the National Cancer Institute. Dr. Munster disclosed leadership positions, stock ownership, and consulting or advisory roles with several companies. Dr. Cardoso disclosed consulting or advisory roles and travel support from multiple companies.
