TOPLINE:

In patients with stage II or III colorectal cancer (CRC), frequent follow-up testing with CT scans and serum carcinoembryonic antigen (CEA) screening provides no significant overall or cancer-specific survival benefits at 10 years, according to findings from a secondary analysis.

METHODOLOGY:

• After curative surgery for CRC, intensive patient follow-up is common in clinical practice. However, there’s limited evidence to suggest that more frequent testing provides a long-term survival benefit.
• In the COLOFOL trial, patients with stage II or III CRC who had undergone curative resection were randomly assigned to either high-frequency follow-up (CT scans and CEA screening at 6, 12, 18, 24, and 36 months) or low-frequency follow-up (testing at 12 and 36 months) after surgery.
• This secondary analysis of the COLOFOL trial included 2456 patients (median age, 65 years), 1227 of whom received high-frequency follow-up and 1229 of whom received low-frequency follow-up.
• The main outcome of the secondary analysis was 10-year overall mortality and CRC–specific mortality rates.
• The analysis included both intention-to-treat and per-protocol approaches, with outcomes measured through December 2020.

TAKEAWAY:

• In the intention-to-treat analysis, the 10-year overall mortality rates were similar between the high- and low-frequency follow-up groups — 27.1% and 28.4%, respectively (risk difference, 1.3%; P = .46).
• A per-protocol analysis confirmed these findings: The 10-year overall mortality risk was 26.4% in the high-frequency group and 27.8% in the low-frequency group.
• The 10-year CRC–specific mortality rate was also similar between the high-frequency and low-frequency groups — 15.6% and 16.0%, respectively — (risk difference, 0.4%; P = .72). The same pattern was seen in the per-protocol analysis, which found a 10-year CRC–specific mortality risk of 15.6% in the high-frequency group and 15.9% in the low-frequency group.
• Subgroup analyses by cancer stage and location (rectal and colon) also revealed no significant differences in mortality outcomes between the two follow-up groups.

IN PRACTICE:

“This secondary analysis of the COLOFOL randomized clinical trial found that, among patients with stage II or III colorectal cancer, more frequent follow-up testing with CT scan and CEA screening, compared with less frequent follow-up, did not result in a significant rate reduction in 10-year overall mortality or colorectal cancer-specific mortality,” the authors concluded. “The results of this trial should be considered as the evidence base for updating clinical guidelines.”

SOURCE:

The study, led by Henrik Toft Sørensen, MD, PhD, DMSc, DSc, Aarhus University Hospital and Aarhus University, Aarhus, Denmark, was published online in JAMA Network Open.

LIMITATIONS:

The staff turnover at recruitment centers potentially affected protocol adherence. The inability to blind patients and physicians to the follow-up frequency was another limitation. The low-frequency follow-up protocol was less intensive than that recommended in the current guidelines by the National Comprehensive Cancer Network and the American Society of Clinical Oncology, potentially limiting comparisons to current standard practices.

DISCLOSURES:

The initial trial received unrestricted grants from multiple organizations including the Nordic Cancer Union, A.P. Møller Foundation, Beckett Foundation, Danish Cancer Society, and Swedish Cancer Foundation project. The authors reported no relevant conflicts of interest.

This transcript has been edited for clarity. 

Matthew F. Watto, MD: I’m Dr Matthew Frank Watto, here with my great friend and America’s primary care physician, Dr Paul Nelson Williams. 

We had a great discussion with Kidney Boy, Dr Joel Topf, everyone’s favorite nephrologist, and he taught us how to manage blood pressure in chronic kidney disease (CKD).

When should I start freaking out about a patient’s kidney function? 

Paul N. Williams, MD: Dr Topf focuses more on albuminuria than we are used to doing. It’s probably one of the most important prognostic indicators of how a patient is going to do from a renal standpoint.

Historically, I’ve tended to focus on the estimated glomerular filtration rate (eGFR), and the lower that number gets, the more I sweat, but albuminuria is probably equally, if not more, important as a way of prognosticating whether a patient is going to progress to dialysis or transplant. He directed us towards this nifty little calculator, kidneyfailurerisk.com, where you plug in the patient’s age, eGFR, and degree of albuminuria, and it spits out their risk of progressing to hemodialysis or renal transplantation over the next 5 years. It’s a nice way to concretely explain to patients their risk for progression.

Instead of telling the patient, “You are high risk,” Dr Topf will say, “Your risk is 6% of needing dialysis in the next 5 years.” You can even use these thresholds to gauge when to refer a patient. If someone has a 5-year risk between 3% and 5% or higher, that patient should probably be seeing a nephrologist.

If their 2-year risk is greater than 20%, that patient probably should be evaluated for transplantation. This gives us have more concrete numbers to work with rather than just saying, “Your kidneys aren’t working as well as we would like and you should see a kidney doctor.” Patients have a better sense of how serious things might be. 

Watto: It’s just easier for them to understand. Dr Topf made the point that we used to have a heat map based on the stage of CKD that would tell you how high a patient’s risk was compared with other people. But patients don’t really understand relative risk, so Dr Topf tells them their absolute risk for ending up on dialysis over the next 2-5 years. 

Patients come in and they are worried because they looked at their lab results and see that their creatinine level is red, or their eGFR is low. They think, It says I have stage 3a CKD. 

We should probably have the stages of CKD start at stage 3, which should be called stage 1 so it doesn’t sound as bad. Patients think they are halfway to dialysis; they are already at stage 3 and didn’t even know their kidneys were a problem. 

Dr Topf said that cystatin C (something I only recently started ordering) can be obtained, and sometimes you can recategorize the patient, especially those with an eGFR between 45 and 60. The cystatin C can predict their renal function better than the creatinine-based equations. If you are using the creatinine equation, he recommends using the 2021 equations.

Another nice thing about cystatin C is that it isn’t tripped up in younger patients with a lot of muscle mass. You just have to watch out for inflammation, which can throw the test off. For example, when a patient is in the intensive care unit, it’s probably not that helpful, but for your outpatients, cystatin C works well. 

Williams: I’ve been using it a fair amount in my patients with more muscle mass. And some patients have been taking creatine as a supplement, and that can alter the numbers as well. This is a nice way to get them out of CKD stage 2 or 3 and back where they belong, with normal healthy functioning kidneys.

Watto: Now, Paul, if we find a patient with more advanced CKD — let’s say stage 4, whether by cystatin C or serum creatinine, and their eGFR is less than 30 — should we start peeling off the angiotensin-converting enzyme ACE inhibitor or the angiotensin receptor blocker (ARB)? Those drugs can raise potassium. What should we do here? 

Williams: That’s the temptation, Matt, and I feel like that was the old orthodoxy, back in residency. It didn’t take much for us to start taking off ACE inhibitors or ARBs once the kidney function started to drop, but it turns out you may be doing more harm than good.

Some data have shown that if you peel off those medications, you actually increase mortality and cardiovascular risk. So, in general, if you can keep them going, the patient will be better off. Hang onto the ACE inhibitors or ARBs as long as you are able to, because they confer a fair amount of benefit.

Watto: As long as the potassium isn’t in red on your lab’s range. It might go up to 5.2 or 5.4, but as long as it’s stable, that should be OK. You probably wouldn’t initiate an ACE inhibitor or ARB or spironolactone with a potassium level above 5, but if it’s below 5 when you start and it goes up slightly after you start the drug, that could be acceptable. 

Another thing we talked about was when a patient progresses to CKD and ends up on dialysis, how helpful are those intradialysis blood pressures in predicting cardiovascular outcomes? 

Williams: For someone who’s performing the dialysis, probably really helpful. In the outpatient setting to predict cardiovascular risk, probably less so. Dr Topf makes the point that the readings are done either shortly after or right when the patient is about to have a large-bore catheter inserted into their arm. And then they have liters of fluid drained out of them. So those numbers are going to have huge amounts of variability. You would not base the patient’s blood pressure treatment solely on those numbers. But regardless of what the numbers are, or even regardless of your office numbers, hopefully you’re working with a nephrologist to make sure that you’re actually in concert and not fighting each other with the blood pressure medications.

Watto: Dr Topf said that a lot of the hypertension in dialysis is because of too much volume. If you can get the volume down, you might be able to peel off blood pressure medications instead of adding more. But some patients have issues with cramping; it’s uncomfortable and not everyone tolerates it. 

I was really surprised to learn that beta blockers, specifically atenolol, have some evidence of improving cardiovascular outcomes in patients on dialysis. Dr Topf speculated that this was because they are largely dying of cardiovascular disease, so maybe that’s why, but that’s one of the places, the only places I can think of aside from thyroid disease, where atenolol really shines.

The heart’s “mini-brain” is independent and highly localized, according to researchers at the Karolinska Institutet in Stockholm, Sweden. The findings could lead to new research into arrhythmia, dementia, and Parkinson’s disease.

Although controlled by the brain, the heart has a separate, smaller intracardiac nervous system (IcNS) embedded within the superficial layers of the heart wall. Nicknamed the mini-brain by researchers decades ago, the IcNS was assumed to be a simple structure capable only of relaying simple information from the brain to the heart.

The neurons in the mini-brain, however, have been under-researched, said Konstantinos Ampatzis, principal researcher and assistant professor of neuroscience at the Karolinska Institutet. “Cardiologists know that neurons exist but never study them because their first concern is the cardiac muscle cells, or cardiomyocytes, that are responsible for the heartbeat,” he explained. “Neuroscientists understand and decode neurons but don’t know about neurons in the heart.”

Ampatzis’s team mapped the exact composition, organization, and function of neurons in the IcNS using zebrafish as an animal model. “The heart of the zebrafish is closer to that of humans than the mouse heart is,” he explained. “The heart rate of a zebrafish is exactly the same.”

Several techniques were used to characterize these neurons. Electrophysiology determined their function, and researchers at Columbia University in New York City helped identify their molecular signatures using single-cell RNA sequencing. Ampatzis and his team also analyzed neurotransmitters that the neurons release to communicate with each other. Researchers in Sweden and New York worked on this project in their spare time because they had no additional funding.

Ampatzis expected to see ganglions or relay neurons capable only of receiving or sending information. “But we found a very diverse set of neurons in a small network,” he said. Their findings included sympathetic, parasympathetic, and sensory neurons with apparent neurochemical and functional diversity. Most surprising was a subset of pacemaker neurons. “You cannot have a network that produces a rhythm without these neurons, and we didn’t expect exactly that, to be honest,” he said.

Pacemaker neurons are usually associated with so-called central pattern generator networks within the central nervous system. These independent, highly localized neuronal networks generate and control complex rhythmic behaviors such as respiration, mastication, urination, and ejaculation. “Most importantly, we found that this neuronal network works in an isolated heart, without brain information, and can change the rhythm of the heart and the regularity by itself,” said Ampatzis.

Further studies confirmed that neurons do not produce the rhythm, which is controlled by the cardiomyocytes. The neurons’ main function is to regulate the speed of the heartbeat. In other words, this smaller localized network acts as a kind of insurance system to safeguard the brain’s control of the heartbeat. “From an evolutionary perspective, I think that the system is like this because the heartbeat defines life,” Ampatzis added.

With the neurons of the heart mapped, medical researchers now have a toolbox of molecular markers, neurotransmitters, and other information on how such neurons function. These findings could become the basis of new research. It might be possible to investigate heart arrhythmia by modulating pacemaker neurons, Ampatzis suggested. “You could even repurpose or find specific drugs that can interfere with this local network of the heart,” he said, adding that this might be a less invasive option than is possible today.

Arrhythmia affects millions of people, said Oliver Guttmann, MD, a consultant cardiologist at The Wellington Hospital and honorary associate professor of cardiology at University College London, both in London, England. Beta-blockers remain the drug of choice for arrhythmia, but other options can be invasive. “We do ablations to try and burn or freeze certain areas of the heart to get rid of a rhythm because often this comes from hyperactive cells somewhere,” he said. Pacemakers and defibrillators are also needed to modulate dangerous rhythms. Innovation is focusing on making interventions far less invasive than they are today by creating smaller and smaller pacemakers, for example.

Moving from zebrafish to more complex mammalian systems will be the next big step, said David Paterson, DPhil, head of the Department of Physiology, Anatomy, and Genetics and honorary director of Burdon Sanderson Cardiac Science Centre at the University of Oxford in England. “If you can find the molecular road map of dysregulation, then that could be a potential target for a gene therapy or cell therapy or for neuromodulation therapy,” he explained. Interest in this field, which is sometimes called bioelectronic medicine, is mounting. “It’s like pharmaceutics, but there’s no drug. You’re tapping into the wiring of the nervous system,” he added.

More radical research pathways might look at ways to tackle neurodegenerative disorders from dementia to Parkinson’s disease. “If neurons die in the brain, then they die in the heart and can affect the rhythm of the heart,” said Ampatzis. But zebrafish neurons are now known to produce substances that induce a proliferation of stem cells in bones, skin, and even the nervous system. “We think those neurons of the heart could perhaps contribute to the regeneration of the heart,” he said.

Ampatzis, Guttmann, and Paterson reported having no relevant financial relationships.

The heart’s “mini-brain” is independent and highly localized, according to researchers at the Karolinska Institutet in Stockholm, Sweden. The findings could lead to new research into arrhythmia, dementia, and Parkinson’s disease.

Although controlled by the brain, the heart has a separate, smaller intracardiac nervous system (IcNS) embedded within the superficial layers of the heart wall. Nicknamed the mini-brain by researchers decades ago, the IcNS was assumed to be a simple structure capable only of relaying simple information from the brain to the heart.

The neurons in the mini-brain, however, have been under-researched, said Konstantinos Ampatzis, principal researcher and assistant professor of neuroscience at the Karolinska Institutet. “Cardiologists know that neurons exist but never study them because their first concern is the cardiac muscle cells, or cardiomyocytes, that are responsible for the heartbeat,” he explained. “Neuroscientists understand and decode neurons but don’t know about neurons in the heart.”

Ampatzis’s team mapped the exact composition, organization, and function of neurons in the IcNS using zebrafish as an animal model. “The heart of the zebrafish is closer to that of humans than the mouse heart is,” he explained. “The heart rate of a zebrafish is exactly the same.”

Several techniques were used to characterize these neurons. Electrophysiology determined their function, and researchers at Columbia University in New York City helped identify their molecular signatures using single-cell RNA sequencing. Ampatzis and his team also analyzed neurotransmitters that the neurons release to communicate with each other. Researchers in Sweden and New York worked on this project in their spare time because they had no additional funding.

Ampatzis expected to see ganglions or relay neurons capable only of receiving or sending information. “But we found a very diverse set of neurons in a small network,” he said. Their findings included sympathetic, parasympathetic, and sensory neurons with apparent neurochemical and functional diversity. Most surprising was a subset of pacemaker neurons. “You cannot have a network that produces a rhythm without these neurons, and we didn’t expect exactly that, to be honest,” he said.

SAN ANTONIO — For patients with so-called “good-risk” ductal carcinoma in situ (DCIS) who did not have radiation therapy after breast-conserving surgery, adjuvant tamoxifen reduced their overall risks for invasive recurrence, but not their risks for recurrence in either the same or contralateral breast.

These findings come from an exploratory analysis of combined data from two clinical trials. They suggest that, for this select group of patients, the choice to forgo radiation following definitive surgery may be an acceptable option, assuming that they follow a full course of endocrine therapy.

“In the absence of survival impact for adjuvant therapy, the decision to recommend radiation therapy or endocrine therapy should be part of a shared decision process, and I think that this data helps us provide clearer data points to our patients to help them make choices between endocrine therapy and radiation therapy in the setting of good-risk [ductal carcinoma in situ],” said Jean L. Wright, MD, from the University of North Carolina at Chapel Hill.

She presented the findings in an oral abstract session and media briefing at San Antonio Breast Cancer Symposium (SABCS) 2024.

 

Trial Results Combined

Wright and colleagues looked at pooled data from two clinical trials that enrolled patients with low- or intermediate-grade DCIS with tumor size no larger than 2.5 cm, grade 1 or 2 lesions, and with surgical margins ≥ 3 mm.

The trials included NRG/RTOG 9804, with 317 patients who fit the “good-risk category,” and ECOG-ACRIN E5194, which included a cohort of 561 patients that met the good-risk definition used for the exploratory analysis.

In each trial, tamoxifen use was optional, and choices were tracked. In the NRG/RTOG trial, 66% of patients used tamoxifen and 34% did not. The respective percentages in the ECOG/ACRIN trial were 30% and 70%.

The majority of patients were adherent to the 5-year prescribed course of tamoxifen, Wright said.

 

Analysis Details

In the combined data, the median age of patients who used tamoxifen vs who did not use tamoxifen was 58 vs 61 years.

In all, 23% of women in both the tamoxifen yes or no groups were premenopausal, with the remainder either postmenopausal or of unknown menopausal status.

After a median follow-up of 14.85 years, the rate of 15-year ipsilateral breast recurrence (IBR) was 19% for patients who did not receive tamoxifen vs 11.4% for those who did. This translated into a hazard ratio for IBR on tamoxifen of 0.52 (P = .001).

Tamoxifen also reduced the risk for invasive recurrence in the same breast, with a 15-year invasive IBR rate of 11.5% in the no tamoxifen group vs 6% in the yes tamoxifen group.

However, as noted before, tamoxifen use was not associated with significant reduction in the risk for noninvasive DCIS recurrence in the same breast, as evidenced by a 15-year DCIS IBR rate of 8.1% without tamoxifen and 5.5% with tamoxifen, a difference that did not reach statistical significance.

 

A Surprising Result

One finding from the data that seemed to defy clinical wisdom was that tamoxifen use did not appear to significantly reduce the risk for events in the other breast. The 15-year rate of contralateral breast events was 8.8% in the no-tamoxifen group vs 5.6% in the yes tamoxifen group, a difference that was not statically significant.

“It was surprising that there was so little effect on contralateral disease,” commented Elinor Sawyer, MBBS, PhD, the invited discussant.

“But I think it’s really important, this decrease in ipsilateral invasive recurrence [with tamoxifen] because there are studies such as the Sloane study from the United Kingdom that show that if you develop an invasive recurrence after DCIS, you have a worse survival than those who develop a pure DCIS recurrence,” she said.

At the media briefing held prior to Wright’s presentation, moderator Virginia Kaklamani, MD, leader of the breast cancer program at UT Health San Antonio in Texas, also said that she found it surprising that tamoxifen did not reduce risk for contralateral breast cancer “since every study that we’ve done has shown that.”

“I also found that result a little bit surprising,” Wright agreed.

“I think the main feature that we want to focus on is that this was a group of patients with a very clear inclusion criteria of this good-risk DCIS, and even though the definition of good-risk DCIS included patients with [tumors] up to 2.5 cm in DCIS, we saw that, in reality, the patients enrolled had very small DCIS. So I’m wondering if it’s perhaps that it’s related to the fact that patients that were enrolled in these studies had really low-risk features and perhaps just had a lower risk of contralateral breast events as compared to a broader population of patients with DCIS,” she said.

The analysis by Wright and colleagues was supported by grants from the National Cancer Institute. Wright reported receiving honoraria from ASTRO and PER. Sawyer disclosed receiving grants/research support from Pfizer, Seagen, and IQIVIA. Kaklamani disclosed serving as a speaker and/or consultant for AstraZeneca, Celldex Therapeutics, Daiichi Sankyo, Genentech, Gilead, Lilly, Menarini, and Novartis and receiving research support from Eisai.

SAN ANTONIO — Second-line treatment with imlunestrant improved progression-free survival compared with standard endocrine monotherapy in patients with advanced estrogen receptor (ER)–positive, human epidermal growth factor receptor 2 (HER2)–negative breast cancer who had ESR1 mutations, according to recent findings from the EMBER-3 trial.

This progression-free survival benefit with imlunestrant did not extend to the overall population, but a combination of imlunestrant plus abemaciclib did lead to a significant improvement in progression-free survival compared with imlunestrant alone, regardless of patients’ ESR1 mutation status.

Lead author Komal Jhaveri, MD, a breast oncologist at Memorial Sloan Kettering Cancer Center in New York City, called the findings “encouraging.”

The phase 3 results raise the possibility of a second-line all-oral targeted therapy option for patients with ER–positive, HER2–negative advanced breast cancer, said Jhaveri, who presented the findings at the San Antonio Breast Cancer Symposium (SABCS) 2024, which were published simultaneously in The New England Journal of Medicine.

However, outside experts provided a note of caution that the trial design may limit how relevant the findings are to clinical practice.

First-line treatment for advanced ER–positive, HER2–negative breast cancer includes an aromatase inhibitor, such as exemestane, and a CDK4/6 inhibitor, such as abemaciclib. However, an ESR1 mutation may develop, which can undermine the effectiveness of the aromatase inhibitor. These patients may swap in a selective estrogen receptor degrader (SERD) — typically, the injectable fulvestrant — in place of the aromatase inhibitor.

Over the past several years, researchers have searched for a better agent than fulvestrant because this injectable drug has limited efficacy in patients with ESR1 mutations, and the monthly intramuscular shots are painful and inconvenient for patients.

The oral SERD imlunestrant is one such candidate.

The EMBER-3 trial initially randomized 661 patients after progression/recurrence evenly to either imlunestrant monotherapy (400 mg once daily) or a standard treatment arm that included either exemestane or fulvestrant, with 90% of these patients receiving fulvestrant. Investigators added a third combination arm shortly after the trial started, which included 213 patients who received imlunestrant plus abemaciclib.

About 60% of the overall population had received prior CDK4/6 inhibitors, primarily palbociclib and ribociclib. About 37% of the study population had ESR1 mutations.

Among patients with ESR1 mutations, imlunestrant monotherapy led to a significant improvement in median progression-free survival of 5.5 months vs 3.8 months in the standard care arm (P < .001). Among all patients, however, progression-free survival was no different between the two arms — 5.6 months in the imlunestrant group vs 5.5 months in the standard care group.

When comparing the two treatment arms in the overall population, the median progression-free survival was significantly better in patients who received imlunestrant plus abemaciclib — 9.4 months vs 5.5 months in the imlunestrant group (hazard ratio [HR] for progression or death, 0.57; P < .001). The progression-free survival benefit held across most patient subgroups, regardless of ESR1 mutation status, as well as among patients who had received a CDK4/6 inhibitor previously.

Data from other studies presented at SABCS indicate that another SERD, elacestrant, in combination with abemaciclib, may provide a similar progression-free survival benefit in this patient population. Elacestrant was approved by the US Food and Drug Administration (FDA) in January 2023 for second-line treatment of patients with advanced breast cancer and ESR1 mutations.

The EMBER trial also reported early overall survival findings. Although immature, overall survival trends favored imlunestrant over the standard treatment. The estimated overall survival at 18 months was 77% in the imlunestrant group and 58.6% in the standard therapy group among patients with ESR1 mutations (HR, 0.55), and 78.6% in the imlunestrant group vs 71.8% in the standard-therapy group for all patients (HR, 0.69).

Common all-grade adverse events with imlunestrant vs standard therapy included fatigue (22.6% vs 13.3%), diarrhea (21.4% vs 11.7%), and nausea (17% vs 13%). Grade 3 or higher anemia and neutropenia were low and similar in both arms.

All-grade diarrhea (86%) and nausea (49%) were more common with the combination of imlunestrant and abemaciclib.

The incidence of grade 3 or higher events was 17% with imlunestrant monotherapy, 21% for standard treatment, and 49% for imlunestrant plus abemaciclib.

EMBER-3 discussant Harold Burstein, MD, PhD, a breast oncologist at the Dana-Farber Cancer Institute, Boston, said that, overall, oral SERDs are starting to “break out from the ESR1 mutation box,” perhaps reflecting the idea that an agent more active than fulvestrant in combination with a non-cross–resistant CDK4/6 inhibitor like abemaciclib might lead to a better long-term outcome, regardless of ESR1 status.

A major limit of EMBER-3, however, is that it did not compare imlunestrant/abemaciclib with fulvestrant/abemaciclib, which would have been a true standard-of-care control, said Burstein.

Kathy Miller, MD, a breast oncologist at Indiana University, Indianapolis, agreed.

She was also concerned about the use of monotherapy in the standard care arm.

“Monotherapy hormone therapy is not what people would be treated with,” Miller said. Patients would typically get fulvestrant with either a targeted therapy or everolimus.

Without appropriate controls, “the data are impossible to interpret” in the context of current practice, Miller told Medscape Medical News.

SAN ANTONIO — Second-line treatment with imlunestrant improved progression-free survival compared with standard endocrine monotherapy in patients with advanced estrogen receptor (ER)–positive, human epidermal growth factor receptor 2 (HER2)–negative breast cancer who had ESR1 mutations, according to recent findings from the EMBER-3 trial.

This progression-free survival benefit with imlunestrant did not extend to the overall population, but a combination of imlunestrant plus abemaciclib did lead to a significant improvement in progression-free survival compared with imlunestrant alone, regardless of patients’ ESR1 mutation status.

Lead author Komal Jhaveri, MD, a breast oncologist at Memorial Sloan Kettering Cancer Center in New York City, called the findings “encouraging.”

The phase 3 results raise the possibility of a second-line all-oral targeted therapy option for patients with ER–positive, HER2–negative advanced breast cancer, said Jhaveri, who presented the findings at the San Antonio Breast Cancer Symposium (SABCS) 2024, which were published simultaneously in The New England Journal of Medicine.

However, outside experts provided a note of caution that the trial design may limit how relevant the findings are to clinical practice.

First-line treatment for advanced ER–positive, HER2–negative breast cancer includes an aromatase inhibitor, such as exemestane, and a CDK4/6 inhibitor, such as abemaciclib. However, an ESR1 mutation may develop, which can undermine the effectiveness of the aromatase inhibitor. These patients may swap in a selective estrogen receptor degrader (SERD) — typically, the injectable fulvestrant — in place of the aromatase inhibitor.

Over the past several years, researchers have searched for a better agent than fulvestrant because this injectable drug has limited efficacy in patients with ESR1 mutations, and the monthly intramuscular shots are painful and inconvenient for patients.

The oral SERD imlunestrant is one such candidate.

The EMBER-3 trial initially randomized 661 patients after progression/recurrence evenly to either imlunestrant monotherapy (400 mg once daily) or a standard treatment arm that included either exemestane or fulvestrant, with 90% of these patients receiving fulvestrant. Investigators added a third combination arm shortly after the trial started, which included 213 patients who received imlunestrant plus abemaciclib.

About 60% of the overall population had received prior CDK4/6 inhibitors, primarily palbociclib and ribociclib. About 37% of the study population had ESR1 mutations.

Among patients with ESR1 mutations, imlunestrant monotherapy led to a significant improvement in median progression-free survival of 5.5 months vs 3.8 months in the standard care arm (P < .001). Among all patients, however, progression-free survival was no different between the two arms — 5.6 months in the imlunestrant group vs 5.5 months in the standard care group.

When comparing the two treatment arms in the overall population, the median progression-free survival was significantly better in patients who received imlunestrant plus abemaciclib — 9.4 months vs 5.5 months in the imlunestrant group (hazard ratio [HR] for progression or death, 0.57; P < .001). The progression-free survival benefit held across most patient subgroups, regardless of ESR1 mutation status, as well as among patients who had received a CDK4/6 inhibitor previously.

Data from other studies presented at SABCS indicate that another SERD, elacestrant, in combination with abemaciclib, may provide a similar progression-free survival benefit in this patient population. Elacestrant was approved by the US Food and Drug Administration (FDA) in January 2023 for second-line treatment of patients with advanced breast cancer and ESR1 mutations.

The EMBER trial also reported early overall survival findings. Although immature, overall survival trends favored imlunestrant over the standard treatment. The estimated overall survival at 18 months was 77% in the imlunestrant group and 58.6% in the standard therapy group among patients with ESR1 mutations (HR, 0.55), and 78.6% in the imlunestrant group vs 71.8% in the standard-therapy group for all patients (HR, 0.69).

Common all-grade adverse events with imlunestrant vs standard therapy included fatigue (22.6% vs 13.3%), diarrhea (21.4% vs 11.7%), and nausea (17% vs 13%). Grade 3 or higher anemia and neutropenia were low and similar in both arms.

All-grade diarrhea (86%) and nausea (49%) were more common with the combination of imlunestrant and abemaciclib.

The incidence of grade 3 or higher events was 17% with imlunestrant monotherapy, 21% for standard treatment, and 49% for imlunestrant plus abemaciclib.

NEW YORK CITY — The total body skin examination with or without dermatoscopy might eventually be marginalized by noninvasive technologies that greatly reduce the need for biopsy while increasing sensitivity and specificity, according to an expert describing four such technologies now in routine use at his own institution.

For skin cancer screening, existing and coming technologies represent “the future of dermatology,” but “we can and should be [already] trying to incorporate these into routine practice,” said Jonathan Ungar, MD, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai, New York City.

 

Technologies such as electrical impedance spectroscopy (EIS), optical coherence tomography (OCT), and reflectance confocal microscopy (RCM) have immediate utility for improving skin cancer detection with fewer biopsies, but this is just the beginning, according to Ungar, who is also medical director of the Kimberly and Eric J. Waldman Melanoma and Skin Cancer Center at Mount Sinai, New York City.

“There is going to be a day when we are not cutting to make a diagnosis,” he said during a presentation at the 27th Annual Winter Symposium — Advances in Medical and Surgical Dermatology (MSWS) 2024.

 

Four Noninvasive Tools Are in Routine Use

Each of these technologies, along with total body photography (TBP), is currently in use at Mount Sinai as well as other tertiary centers to improve diagnostic accuracy at the same time they reduce invasive tests. The initial excitement about these technologies was based on their potential to avoid biopsy in cosmetically sensitive areas, but Ungar suggested that wider application is being driven by better rates of detection, less morbidity, and improved patient satisfaction.

Patients are happy to avoid invasive procedures whenever they can, Ungar noted. In addition to concern about pain or discomfort and a small but measurable risk for infection, patients face a wound that requires healing and the potential for an enduring scar whether the histology is positive for a malignancy.

While none of the four technologies Ungar outlined typically provide a yes or no answer regarding the presence of a malignancy, they do improve diagnostic accuracy with a lower rate of biopsy.

 

Each Noninvasive Tool Reduces Biopsy Rates

In the case of EIS, for example, the impedance of a painless and harmless electrical current directed into the skin with a handheld probe differentiates normal from abnormal skin through an EIS algorithm. Ungar said it does not require training. A result negative for an abnormality has about a 90% predictive value, and it means that a biopsy can be avoided if there are no other reasons for suspicion.

With a price estimated in the thousands of dollars, the device and software are “not so expensive,” particularly when the tool results in fewer biopsies, Ungar noted.

OCT has a similar profile. Again, used as an adjunct to other types of evaluations, including a history and visual inspection, this helps in modulating suspicion of malignancy. In published studies, OCT has proven superior to dermatoscopy for cancer detection. Citing a 14-study meta-analysis, Ungar said that the sensitivity of OCT for melanoma exceeds, and the specificity approaches, 90%. For basal cell cancers, it is even better.

RCM involves directing a laser into the skin to detect abnormal cells that reflect light. It enables visualization of the skin by layers to the papillary dermis in a detail that is comparable with histology, according to Ungar. Imaging performed with the device used at Mount Sinai (VivaScope 1500, Caliber Imaging & Diagnostics) is reimbursed by Medicare.

Once comfortable with the technology, scanning and interpretation take slightly more time than that required of EIS or OCT, but, like the others, it is painless and helpful for determining whether further evaluation is needed, according to Ungar.

“It is extremely useful in reducing the number of biopsies,” whether melanoma or basal cell malignancies, he said.

 

Total Body Photograph Helps With Serial Screens

While not specifically a diagnostic tool, TBP can also play a role in reducing biopsies through its highly efficient ability to document the evolution of lesions over time.

As its name implies, essentially the entire body surface is captured by multiple cameras mounted in a circle around the patient. Unlike sequential photos that require far more time to take and store and are challenging to organize and retrieve, the device used at Mount Sinai (Vectra Wb180 1360, Canfield Scientific) can complete the photos in about 2 minutes.

Software for organizing and storing the photos, to which dermatoscope images of individual lesions can be attached if helpful, results in efficient retrieval of photos at sequential visits for evaluating change in any specific lesion.

“It is very easy to use,” according to Ungar, who noted that although the underlying idea is not, the technology of taking, storing, and retrieving photographs has been “perhaps perfected” with this approach.

 

Noninvasive Screening Training Is Appropriate

Year after year, dermatology residents undergo intensive instruction to master the traditional methods of skin examination with the naked eye and the help of a dermatoscope, but Ungar considers the noninvasive tools to be another step forward. They lower miss rates while reducing the need for histopathology.

Adding these new technologies to routine patient care resonates for many experts, even if the protocols of when to use with the tool are not well established.

Angela J. Lamb, MD, an associate professor of dermatology at Mount Sinai, who has been following the work of Ungar with interest, sees merit in his argument. Not surprisingly, she thinks that any approach shown to boost skin cancer detection is something that deserves attention, but she thinks the effort to safely eliminate biopsies with a low likelihood of a positive finding cannot be ignored.

“Patients want to avoid biopsies when they can,” Lamb told this news organization, and she does not think this is limited to biopsies on the face or other cosmetically sensitive areas.

As a result, she said that she does see the rationale for incorporating the newer technologies into routine care and called this an “important” effort to improve the patient experience as well as reduce missed lesions.

Ungar reported financial relationships with AbbVie, Bristol-Myers Squibb, Castle Biosciences, Dermavant, Janssen Pharmaceuticals, Menlo Therapeutics, Mitsubishi Tanabe Pharma America, and UCB. Lamb reported no potential conflicts of interest.

TOPLINE:

InterRhythmic care (IRC), a novel digital intervention, was linked to greater improvements in depressive symptoms, anxiety, interpersonal relationships, and social functioning in patients with major depressive disorder (MDD), compared with internet general psychoeducation in new research.

METHODOLOGY:

• The randomized, single-blind trial included 120 outpatients from the Shanghai Mental Health Center between March and November 2021 with MDD (mean age, 28.2 years; 99% Han Chinese; 83% women) who were randomly assigned to receive either IRC or internet general psychoeducation (control group).
• IRC included computer-based psychoeducation on stabilizing social rhythm regularity and resolution of interpersonal problems plus brief online interactions with clinicians. Patients received 10 minutes of IRC daily, Monday through Friday, for 8 weeks.
• The researchers assessed participants’ depressive symptoms, anxiety symptoms, interpersonal relationships, social function, and biological rhythms using the 17-item Hamilton Depression Rating Scale, Hamilton Anxiety Scale, Interpersonal Comprehensive Diagnostic Scale, Sheehan Disability Scale, and Morning and Evening Questionnaire at baseline and at 8 weeks.

TAKEAWAY:

• The participants who received IRC had significantly lower Hamilton Depression Rating total scores than those who received internet general psychoeducation (P < .001).
• The IRC group demonstrated improved anxiety symptoms, as evidenced by lower Hamilton Anxiety Scale total scores, than those observed for the control group (P < .001).
• The IRC group also showed improved outcomes in interpersonal relationships, as indicated by lower Interpersonal Comprehensive Diagnostic Scale total scores (P < .001).
• Social functioning improved significantly in the IRC group, as measured by the Sheehan Disability Scale subscores for work/school (P = .03), social life (P < .001), and family life (P = .001).

IN PRACTICE:

“This study demonstrated that IRC can improve clinical symptoms such as depressive symptoms, anxiety symptoms, interpersonal problems, and social function in patients with MDD. Our study suggested that the IRC can be used in clinical practice,” the investigators wrote.

SOURCE:

The study was led by Chuchen Xu, Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine in China. It was published online on November 20, 2024, in The Journal of Psychiatric Research.

LIMITATIONS:

The 8-week follow-up period was considered too short to comprehensively evaluate the intervention’s long-term impact. Additionally, the researchers had to check and supervise assignment completion, which increased research costs and may, therefore, potentially limit broader implementation.

DISCLOSURES:

The investigators reported no conflicts of interest.

• The randomized, single-blind trial included 120 outpatients from the Shanghai Mental Health Center between March and November 2021 with MDD (mean age, 28.2 years; 99% Han Chinese; 83% women) who were randomly assigned to receive either IRC or internet general psychoeducation (control group).
• IRC included computer-based psychoeducation on stabilizing social rhythm regularity and resolution of interpersonal problems plus brief online interactions with clinicians. Patients received 10 minutes of IRC daily, Monday through Friday, for 8 weeks.
• The researchers assessed participants’ depressive symptoms, anxiety symptoms, interpersonal relationships, social function, and biological rhythms using the 17-item Hamilton Depression Rating Scale, Hamilton Anxiety Scale, Interpersonal Comprehensive Diagnostic Scale, Sheehan Disability Scale, and Morning and Evening Questionnaire at baseline and at 8 weeks.

TAKEAWAY:

• The participants who received IRC had significantly lower Hamilton Depression Rating total scores than those who received internet general psychoeducation (P < .001).
• The IRC group demonstrated improved anxiety symptoms, as evidenced by lower Hamilton Anxiety Scale total scores, than those observed for the control group (P < .001).
• The IRC group also showed improved outcomes in interpersonal relationships, as indicated by lower Interpersonal Comprehensive Diagnostic Scale total scores (P < .001).
• Social functioning improved significantly in the IRC group, as measured by the Sheehan Disability Scale subscores for work/school (P = .03), social life (P < .001), and family life (P = .001).

IN PRACTICE:

“This study demonstrated that IRC can improve clinical symptoms such as depressive symptoms, anxiety symptoms, interpersonal problems, and social function in patients with MDD. Our study suggested that the IRC can be used in clinical practice,” the investigators wrote.

SOURCE:

The study was led by Chuchen Xu, Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine in China. It was published online on November 20, 2024, in The Journal of Psychiatric Research.

LIMITATIONS:

The 8-week follow-up period was considered too short to comprehensively evaluate the intervention’s long-term impact. Additionally, the researchers had to check and supervise assignment completion, which increased research costs and may, therefore, potentially limit broader implementation.

DISCLOSURES:

The investigators reported no conflicts of interest.

The first study funded by the US Department of Veterans Affairs (VA) for psychedelic-assisted therapy since the 1960s is currently enrolling veterans. Researchers are set to evaluate the potential of methylenedioxymethamphetamine (MDMA) for veterans with posttraumatic stress disorder (PTSD) and alcohol use disorder.   
 

The grant—about $1.5 million over 5 years—will fund a randomized, placebo-controlled trial at the Providence VA Medical Center in Rhode Island and the West Haven VA Medical Center in Connecticut by VA researchers affiliated with Brown University and Yale University. Pharmaceutical-grade MDMA will be used, and some participants will be randomly selected to receive an active placebo (lower dose of MDMA). MDMA is a psychedelic compound believed to increase emotional openness, reduce fear, and promote introspection during therapy. 
 

The study is part of the VA’s broader effort to gather definitive scientific evidence on the potential efficacy and safety of psychedelic compounds used in conjunction with psychotherapy to treat PTSD, depression, and related mental health conditions. Veterans service organizations like the American Legion and Disabled American Veterans in addition to mental health clinician groups have also called for expanded research into psychedelic compounds. The National Defense Authorization Act for fiscal year 2024 also authorized the US Department of Defense to perform research on psychedelics within military populations. 
 

In September 2023, VA and other federal clinicians, scientists, and policy makers assessed the state of scientific evidence regarding psychedelic-assisted therapies. The working groups provided advice to VA leadership, including the recommendation for the VA to begin funding its own research into these areas of care.  
 

The guidance was based on previously published studies that have found encouraging results but included few or no veteran participants. For example, a confirmatory phase 3 study by the MAPP2 Study Collaborator Group involved 104 patients, of whom only 16 were veterans.  
 

However, the findings of that study underscored the potential of the treatment: MDMA significantly improved PTSD symptoms and functional impairment, compared with placebo with therapy over 18 weeks. Notably, 45 of 52 (86%) participants treated with MDMA achieved a clinically meaningful benefit, and 37 of 52 (71%) participants no longer met criteria for PTSD by the end of the study. Consistent with an earlier study, no new major safety issues were reported. Common treatment-emergent adverse effects were like those of previous research and consistent with expected effects of MDMA. MDMA did not appear to increase the risk of suicidal ideation, and no suicidal behavior was observed. 
 

The VA researchers has conducted a limited number of small studies on psychedelics in VA facilities using non-VA funding. “VA is on the cutting edge of clinical research for veteran health, including in the investigation of psychedelics for mental health,” said Under Secretary for Health Shereef Elnahal, MD.  
 

The FDA granted breakthrough therapy status for MDMA in the treatment of PTSD and psilocybin for the treatment of depression in 2017 and 2018, respectively, based on promising preliminary research evidence. However, in June 2024 an FDA panel voted against approving a MDMA therapy for PTSD, citing concerns about research practices, a lack of diversity in the trials, and a failure to provide data on adverse effects such as potential for abuse.  
 

In August, the FDA formally rejected the treatment and called for another phase 3 study. “The FDA’s decision is disgraceful,” said Heroic Hearts Project, a veterans organization that had lobbied for FDA approval citing the many veteran suicides in a statement. “This is the epitome of bureaucratic red tape—and the result is people will keep dying.” 
 

Meanwhile, VA Press Secretary Terrence Hayes said in a statement: “VA is committed to high-quality research that safely promotes the health of our nation’s Veterans … VA anticipates that additional insights on the efficacy and safety of these therapies will add to the broader body of knowledge on MDMA-assisted psychotherapy.”

TOPLINE:

A survey of dermatologists reveals hypertrophic or traumatic scars, acne, and hyperhidrosis as the top pediatric cosmetic concerns, and vascular lasers, laser hair removal, and lasers for pigmentation among the most common treatments.

METHODOLOGY:

• An anonymous online survey conducted with SurveyMonkey targeted healthcare providers who routinely used lasers to treat cutaneous conditions in pediatric patients.
• The survey included members of the Society for Pediatric Dermatology and the American Society for Laser Medicine and Surgery and Surgery, as well as fellowship directors and current fellows of the American Society for Dermatologic Surgery.
• A total of 85 practitioners responded to the survey, with 86% answering all questions; respondents primarily included pediatric dermatologists (77.65%), general dermatologists (18.82%), cosmetic dermatologists (8.24%), and dermatologic/Mohs surgeons (1.18%).

TAKEAWAY:

• Hypertrophic or traumatic scars ranked as the most frequently treated pediatric cosmetic condition (95.29%), followed by acne (89.41%), axillary and facial hyperhidrosis (77.65%), hypertrichosis/hirsutism (67.06%), and pigmented lesion removal (64.71%).
• The most common procedures performed were vascular lasers (77.65%), laser hair removal (50.59%), lasers for pigmentation (28.24%), neuromodulators (25.88%), and laser skin resurfacing (22.35%).
• Additional treatments respondents performed included chemical peels (20.00%), radiofrequency microneedling (16.47%), soft tissue fillers (4.71%), and cryolipolysis/body contouring (4.17%).
• About 50% of respondents said they would start cosmetic treatment of acne, and about 66% said they would start laser hair removal treatment between the ages of 12 and 15 years.

IN PRACTICE:

Noting that the survey results provided insight into the types of cosmetic procedures being performed for pediatric patients, the authors wrote, “These interventions can play a significant role in addressing the emotional and social challenges faced by pediatric patients with cosmetic concerns, allowing them to navigate social interactions more confidently and positively.” Before any procedure, they added, “It is important that any comorbid conditions be addressed,” they added, and “ethical considerations regarding informed consent, patient autonomy, and long-term consequences should be carefully weighed, given the vulnerable nature of pediatric patients.”

SOURCE:

The study was led by Lauren Hoffman, MD, who practices dermatology in Great Neck, New York. It was published online in December 2024 in Dermatologic Surgery.

LIMITATIONS:

The study was subjective in nature and had a small sample size, and the exact number of survey recipients was unclear, hindering an accurate calculation of the response rate. The absolute number of responses accounted for a small portion of the total memberships of the participating societies. Also, the data collection periods varied among the three academic societies, and dermatologists’ practice types may have influenced the range and nature of treated conditions.

DISCLOSURES:

The authors did not disclose funding information. They declared no conflicts of interest.

SAN DIEGO — The multiple myeloma (MM) drug daratumumab (Darzalex), an anti-CD38 monoclonal antibody, dramatically reduced progression to active MM or death in patients with high-risk smoldering MM (SMM), a landmark randomized, open-label, phase 3 study found.

Among 390 patients with SMM (194 assigned to daratumumab and 196 to active monitoring), progression to active MM or death over a follow-up of 65.2 (0-76.6) months was 51% lower in the daratumumab group vs active monitoring (34.5% vs 50.5%, hazard ratio [HR], 0.49; 95% CI, 0.36-0.67; P < .0001), researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting and in a simultaneous publication in the New England Journal of Medicine.

Rahul Banerjee, MD, an assistant professor with the University of Washington and Fred Hutchinson Cancer Center, both in Seattle, who wasn’t involved with the research, said the study “is a big deal, and I suspect this will ultimately lead to an FDA [Food and Drug Administration] approval for daratumumab in this setting. If using daratumumab up-front can prevent further myeloma and therefore make patients live longer, this would be immediately adopted at many practices.”

As study first author Meletios Athanasios Dimopoulos, MD, of National and Kapodistrian University of Athens and Alexandra General Hospital in Greece, noted at a news briefing, SMM is common, affecting 0.5% of the population aged over 40, per a 2023 Iceland study.

“Standard practice is close follow-up without immediate intervention. However, this oftentimes ends in organ tissue damage, and hypercalcemia, bone lesions, renal impairment, and anemia,” Dimopoulos said.

According to him, researchers launched the AQUILA study in light of indications that daratumumab may benefit patients with intermediate- and high-risk SMM.

For the study, researchers recruited patients from 2017 to 2019 in 23 countries with confirmed high-risk SMM for ≤ 5 years (median age, 64 [31-86] years; 47%-49% men; 83% White).

In the daratumumab group, the drug was administered in 28-day cycles until cycle 39, 36 months, or disease progression, whichever came first (median treatment duration, 38 months [35 months]).

At 5 years, progression-free survival (PFS) — the primary endpoint — was 63.1% (daratumumab) and 40.8% (active monitoring). Researchers estimated 60-month PFS rates at 63.1% and 40.8%, respectively, and overall response rates were 63.4% vs 2.0% (P < .0001), respectively.

The 60-month overall survival rates were 93.0% and 86.9% (HR, 0.52; 95% CI, 0.27-0.98) with 15 deaths in the daratumumab and 26 in the active monitoring group.

“During the follow-up period, there was continuous improvement in favor of the daratumumab arm,” Dimopoulos said. “Even after treatment was discontinued at 3 years, or even at 5 or 6 years, there was a continuous benefit from treatment with daratumumab.”

By clinical cutoff in May 2024, 65% of patients taking daratumumab had finished 39 cycles/3 years of treatment vs 40.8% in the active monitoring group. Progressive disease was the most common reason that patients stopped treatment (21.8% and 41.8% of patients in the groups, respectively).

Grade 3/4 treatment-emergent adverse events (TEAEs) occurred in 40.4% (daratumumab) and 30.1% (active monitoring) of patients. The most common was hypertension (5.7% and 4.6%, respectively).

In the daratumumab group, 5.7% discontinued therapy because of TEAEs, which the researchers described as a “low” number, and fatal TEAEs were similar in both groups (1.0% and 2.0%, respectively).

Banerjee said that “one theoretical risk of using daratumumab monotherapy to treat perceived high-risk SMM is that if the patient actually has active multiple myeloma, you are undertreating them. For anyone with HR-SMM, active multiple myeloma must be completely ruled out. I always insist on both a PET-CT and a whole-body MRI to evaluate the bone marrow comprehensively.”

For now, Banerjee said, clinicians should wait for the US Food and Drug Administration approval before prescribing daratumumab for high-risk SMM.

Are there alternatives to reduce the risk for SMM turning into MM? “Generally, I advise close observation in most cases, but we do have clinical trials in this space,” Banerjee said. “Technically, it is possible to consider lenalidomide monotherapy in SMM based on the results of a large phase 3 study. But lenalidomide is expensive and has many side effects. Insurance companies often won’t cover it fully, and patients almost always have at least one side effect.”

Also, he added, “only half of patients saw their high-risk SMM disease burden drop. Lenalidomide also has a clear link to rare, delayed toxicities such as second primary malignancies, which makes us nervous.”

Janssen Pharmaceuticals, the maker of daratumumab, funded the study. Dimopoulos disclosed ties with Sanofi, Regeneron, Menarini, Takeda, GSK, BMS, Janssen Pharmaceuticals, BeiGene, Swixx, AstraZeneca, and Amgen. Banerjee disclosed ties with AbbVie, Adaptive, BMS, Caribou, Genentech/Roche, GSK, Karyopharm Therapeutics, Legend, Johnson & Johnson, Novartis, Pack, Pfizer, Prothena, Sanofi Pasteur, and SparkCures. Some other authors reported various and multiple disclosures, including ties with Janssen Pharmaceuticals.

At 5 years, progression-free survival (PFS) — the primary endpoint — was 63.1% (daratumumab) and 40.8% (active monitoring). Researchers estimated 60-month PFS rates at 63.1% and 40.8%, respectively, and overall response rates were 63.4% vs 2.0% (P < .0001), respectively.

The 60-month overall survival rates were 93.0% and 86.9% (HR, 0.52; 95% CI, 0.27-0.98) with 15 deaths in the daratumumab and 26 in the active monitoring group.

“During the follow-up period, there was continuous improvement in favor of the daratumumab arm,” Dimopoulos said. “Even after treatment was discontinued at 3 years, or even at 5 or 6 years, there was a continuous benefit from treatment with daratumumab.”

By clinical cutoff in May 2024, 65% of patients taking daratumumab had finished 39 cycles/3 years of treatment vs 40.8% in the active monitoring group. Progressive disease was the most common reason that patients stopped treatment (21.8% and 41.8% of patients in the groups, respectively).

Grade 3/4 treatment-emergent adverse events (TEAEs) occurred in 40.4% (daratumumab) and 30.1% (active monitoring) of patients. The most common was hypertension (5.7% and 4.6%, respectively).

In the daratumumab group, 5.7% discontinued therapy because of TEAEs, which the researchers described as a “low” number, and fatal TEAEs were similar in both groups (1.0% and 2.0%, respectively).

Banerjee said that “one theoretical risk of using daratumumab monotherapy to treat perceived high-risk SMM is that if the patient actually has active multiple myeloma, you are undertreating them. For anyone with HR-SMM, active multiple myeloma must be completely ruled out. I always insist on both a PET-CT and a whole-body MRI to evaluate the bone marrow comprehensively.”

For now, Banerjee said, clinicians should wait for the US Food and Drug Administration approval before prescribing daratumumab for high-risk SMM.

Are there alternatives to reduce the risk for SMM turning into MM? “Generally, I advise close observation in most cases, but we do have clinical trials in this space,” Banerjee said. “Technically, it is possible to consider lenalidomide monotherapy in SMM based on the results of a large phase 3 study. But lenalidomide is expensive and has many side effects. Insurance companies often won’t cover it fully, and patients almost always have at least one side effect.”

Also, he added, “only half of patients saw their high-risk SMM disease burden drop. Lenalidomide also has a clear link to rare, delayed toxicities such as second primary malignancies, which makes us nervous.”

Janssen Pharmaceuticals, the maker of daratumumab, funded the study. Dimopoulos disclosed ties with Sanofi, Regeneron, Menarini, Takeda, GSK, BMS, Janssen Pharmaceuticals, BeiGene, Swixx, AstraZeneca, and Amgen. Banerjee disclosed ties with AbbVie, Adaptive, BMS, Caribou, Genentech/Roche, GSK, Karyopharm Therapeutics, Legend, Johnson & Johnson, Novartis, Pack, Pfizer, Prothena, Sanofi Pasteur, and SparkCures. Some other authors reported various and multiple disclosures, including ties with Janssen Pharmaceuticals.

SAN DIEGO — The multiple myeloma (MM) drug daratumumab (Darzalex), an anti-CD38 monoclonal antibody, dramatically reduced progression to active MM or death in patients with high-risk smoldering MM (SMM), a landmark randomized, open-label, phase 3 study found.

Among 390 patients with SMM (194 assigned to daratumumab and 196 to active monitoring), progression to active MM or death over a follow-up of 65.2 (0-76.6) months was 51% lower in the daratumumab group vs active monitoring (34.5% vs 50.5%, hazard ratio [HR], 0.49; 95% CI, 0.36-0.67; P < .0001), researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting and in a simultaneous publication in the New England Journal of Medicine.

Rahul Banerjee, MD, an assistant professor with the University of Washington and Fred Hutchinson Cancer Center, both in Seattle, who wasn’t involved with the research, said the study “is a big deal, and I suspect this will ultimately lead to an FDA [Food and Drug Administration] approval for daratumumab in this setting. If using daratumumab up-front can prevent further myeloma and therefore make patients live longer, this would be immediately adopted at many practices.”

As study first author Meletios Athanasios Dimopoulos, MD, of National and Kapodistrian University of Athens and Alexandra General Hospital in Greece, noted at a news briefing, SMM is common, affecting 0.5% of the population aged over 40, per a 2023 Iceland study.

“Standard practice is close follow-up without immediate intervention. However, this oftentimes ends in organ tissue damage, and hypercalcemia, bone lesions, renal impairment, and anemia,” Dimopoulos said.

According to him, researchers launched the AQUILA study in light of indications that daratumumab may benefit patients with intermediate- and high-risk SMM.

For the study, researchers recruited patients from 2017 to 2019 in 23 countries with confirmed high-risk SMM for ≤ 5 years (median age, 64 [31-86] years; 47%-49% men; 83% White).
