In myasthenia gravis, antibodies pass open-label tests
PHOENIX – . The two drugs, rozanolixizumab (Rystiggo, UCB) and efgartigimod PH20 (Vyvgart, Argenx SE), received Food and Drug Administration approval in June 2023 and December 2021, respectively, for the treatment of MG.
The neonatal Fc receptor binds to IgG within cells and recycles it back into the blood, leading to increased serum levels. The antibodies bind to the neonatal Fc receptor and promote its degradation, therefore preventing IgG recycling without interfering with its production. They do not affect the levels of other immunoglobulin isotypes.
At the 2023 annual meeting of the American Association for Neuromuscular and Electrodiagnostic Medicine (AANEM), researchers presented data from an open-label extension study following the phase 3 MycarinG trial of rozanolixizumab and the ADAPT-SC+ study of efgartigimod.
In the MycarinG study, rozanolixizumab “showed both statistically significant and clinically meaningful improvements in multiple endpoints,” said Vera Bril, MD, during a presentation of the results.
Rozanolixizumab is approved for MG patients who are anti–acetylcholine receptor (AchR) or anti–muscle-specific tyrosine kinase (MuSK) antibody positive. Efgartigimod is approved for MG patients who are AChR positive.
After completing MycarinG, patients were eligible to enroll in one of two open-label studies, one of each dose.
The new efficacy analysis focused on 110 patients who underwent two or more consecutive symptom-driven treatment cycles. A safety analysis focused on 188 patients who received at least one cycle of treatment.
“The post hoc analysis showed that the clinically meaningful improvements in the generalized myasthenia gravis symptoms were maintained over time for the cohort across rozanolixizumab cycles, while individual patients move through the consecutive treatment cycles, rozanolixizumab had an acceptable safety profile that was maintained across repeated treatments cycles. This is consistent with previous results of rozanolixizumab,” said Dr. Bril, who is a clinical investigator at University of Toronto
A reduction in steroid use?
During the Q&A session, George Small, MD, asked if the study had shown a reduction in steroid use among patients with MG.
As clinical associate director of neurology at Allegheny Medical Center, Pittsburgh, he has overseen the care of several hundred patients with generalized MG, as well as participated in clinical trials. “Many physicians use steroids for very quick responses in their patients. I love steroids and I hate steroids. I’ve helped save people’s lives with them, but I’ve also probably hastened their demise, unfortunately, because of the long-term side effects of the medications. Many neurologists in the community will over-utilize steroids because they don’t have access to these more expensive therapies. I look forward to both using these medications more as they become FDA approved and being an advocate for them, because it is my belief that they help decrease the use of steroids,” said Dr. Small in an interview.
Even if new medications do reduce steroid use, there remains a hurdle with insurance companies. “I’ve felt I’ve been forced to use treatments that I know may not be efficacious in the short term in order to get authorization for more expensive therapies that I use now. I’ve had patients admitted to the hospital as I’ve tried to jump through hoops that the insurance companies demanded,” said Dr. Small.
Clinical improvements seen
In the MycarinG study, patients received weekly injections of 7 mg/kg, 10 mg/kg rozanolixizumab, or placebo over a 6-week period. Both treatment groups had reductions in Myasthenia Gravis Activities of Daily Living (MG-ADL) scores compared with placebo.
MG-ADL and Quantitative Myasthenia Gravis (QMG) scores were consistent across treatment cycles. The mean MG-ADL score dropped by about 4 points at week 6. At around week 10, the mean improvement declined to 2 points, and then by week 14 it increased to 3 points, where it remained consistent out to 50 weeks. A similar pattern was seen in QMG scores, with an approximate 5-point drop at 6 weeks, then about a 1.5-point improvement at 10 weeks, then a mean decrease of around 4 points that stayed stable out to 50 weeks.
Over all cycles of treatment, 89.9% of patients experienced a treatment-emergent adverse event, including 22.3% who had a serious TEAE; the study dropout rate because of TEAEs was 15.4%.
In the ADAPT-SC study, 110 patients were randomized to 10 mg/kg intravenous efgartigimod or 1,000 mg efgartigimod PH20, which is formulated with recombinant human hyaluronidase to allow for rapid administration of larger volumes. After completion of ADAPT-SC, 105 patients from both groups and an additional 79 patients entered the open-label extension study with 1,000 mg efgartigimod PH20.
The study included 141 patients who were AChR-Ab positive and 38 who were AChR-Ab negative. In the first cycle, 34.6% experienced an injection-site reaction, which steadily dropped to 11.5% by the sixth cycle. After each cycle of treatment, the mean change in MG-ADL from study baseline at week 4 was between 4.1 and 4.7 points. The mean change in Myasthenia Gravis Quality of Life 15-Item Questionnaire revisited from study baseline at week 4 was between 5.1 and 6.5 points. The mean change in EuroQoL 5-dimension, 5-level visual analog scale was between 12.3 and 16.0 points at week 4.
MyCarinG was funded by UCB Pharma. ADAPT-SC was funded by Argenx SE. Dr. Bril has financial relationships with Behring, Argenyx, Alexion, Immunovant, Alnylam, Akcea, Takeda, Sanofi, Ionis, Roche, Novo Nordisk, Octapharma, Momenta, Pfizer, CSL Behring, Grifols, Powell Mansfield, UCB, and Viela Bio.

FDA OKs new treatment for erosive esophagitis
also known as erosive gastroesophageal reflux disease (GERD), as well as relief of associated heartburn, the company has announced.
Vonoprazan, an oral potassium-competitive acid blocker (PCAB), provides more potent inhibition of gastric acid than do proton pump inhibitors (PPIs) and is seen as a potential alternative.
The approval of vonoprazan for erosive GERD was based on results from the phase 3 PHALCON-EE study.
The randomized, double-blind, multicenter study enrolled 1,024 patients with erosive GERD in the United States and Europe and compared vonoprazan with the PPI lansoprazole (Prevacid) in the healing and maintenance of healing of erosive GERD and associated heartburn symptom relief.
Vonoprazan 20 mg was noninferior to lansoprazole 30 mg for complete healing by week 8 in patients with all grades of erosive GERD, with healing rates of 93% vs. 85% for lansoprazole.
In addition, vonoprazan showed superior rates of healing in patients with moderate to severe disease (LA Grade C/D) at week 2 (70% vs. 53% with lansoprazole). Vonoprazan was also noninferior to lansoprazole in terms of heartburn-free days over the healing period.
In the maintenance phase of the trial, vonoprazan 10 mg was superior to lansoprazole 15 mg in maintaining healing at 6 months in all patients who were randomly assigned (79% vs. 72%) and in the subset of patients with moderate to severe erosive GERD (75% vs. 61%).
Adverse event (AE) rates for vonoprazan were comparable to lansoprazole. The most common AEs in the healing phase (≥ 2% with vonoprazan) were gastritis, diarrhea, abdominal distention, abdominal pain, and nausea.
The most common AEs in the maintenance phase (≥ 3% with vonoprazan) were gastritis, abdominal pain, dyspepsia, hypertension, and urinary tract infection.
“For many GERD patients with erosive esophagitis, the response to current treatment is suboptimal, leaving them with incomplete healing and ongoing symptoms,” Colin W. Howden, MD, professor emeritus, University of Tennessee, Memphis, said in the news release.
Vonoprazan provides clinicians with a “new first-in-class therapeutic option that demonstrated faster healing in the more difficult-to-treat GERD patients with erosive esophagitis,” Dr. Howden added.
Vonoprazan is expected to be available in the United States in December.
The FDA also recently approved reformulated vonoprazan tablets for Voquezna Triple Pak (vonoprazan, amoxicillin, clarithromycin) and Voquezna Dual Pak (vonoprazan, amoxicillin) for the treatment of Helicobacter pylori infection in adults, Phathom Pharmaceuticals announced.
In February, the FDA had put both the vonoprazan new drug application for erosive esophagitis and the postapproval supplement for H. pylori on hold until the company addressed concerns over the presence of nitrosamine impurities.

DLBCL treatment options: CAR T outperforms ASCT
NEW YORK – according to evidence presented at the 2023 Lymphoma, Leukemia, and Myeloma Congress.
DLBCL is characterized by the National Institutes of Health as an aggressive malignancy and the most common lymphoma. Research presented at the conference indicated that 60%70% of patients were cured with six to eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP).
“In the past, if a relapsed of refractory DLBCL patient couldn’t get a transplant, they were likely headed for palliative care. CAR T-cell therapy is no longer experimental. Not only can we offer it to patients who are ineligible for transplant (and manage the side effects), the treatment has proven to offer better overall survival and cure rates, even in patients who eligible for ASCT,” said presenter Jason Westin, MD, director of the lymphoma clinical research program at the University of Texas MD Anderson Cancer Center, Houston.
The ZUMA-7 phase 3trial among patients with early r/r DLBCL demonstrated the superiority of CAR T-cell therapy with the agent, axicabtagene ciloleucel (YESCARTA, Kita Pharma) versus standard of care (chemoimmunotherapy followed by high-dose chemotherapy and ASCT). Those in the axicabtagene ciloleucel (axi-cel) group had a median progression free survival (PFS) of 14.7 months and an estimated 4-year overall survival (OS) rate of 54.6% compared to 3.7 months and 46% in the control group.
Patients treated with axi-cel experienced a higher rate of adverse events (AE) grade 3 of higher, compared with the ACST group (91% vs. 83%) Furthermore, patients who received axi-cel had cytokine release syndrome (6%) and neurologic events in (21%) grade 3 or higher, compared with 0% and less than 1% in the ASCT group.
At the conference, Dr. Westin’s copanelist Jennifer Amengual, MD, of Columbia University Irving Medical Center, New York, interpreted the data on adverse events (AEs) from ZUMA-7 to mean that if a patient is especially susceptible to CAR T side effects, then ASCT could be preferred. She also outlined a second strategy that shows promise when a patient has either failed CAR T and ASCT or whose frailty demands an approach that avoids AEs.
Dr. Amengual cited a study in which patients with r/r DLBCL were treated with the bispecific antibody glofitamab (Columvi/Roche), which induced a complete response in 39% of patients at a median follow-up of 12.6 months and a 12-month PFS rate of 37%. Those treated with the agent experienced cytokine release syndrome and neurologic events grade 3 or higher, at a rate of 4% and 3% respectively.
“Efforts to make off-the-shelf CAR T therapy are ongoing. With some fine-tuning the PFS and OS with bispecific antibodies will likely approach or exceed both CAR T and ACST. The fact that they could come right off the shelf, rather than having to be tailor made for each patient, gives them a huge advantage in terms of cost and availability, while maintaining what appears to be an excellent safety profile” said Morton Colman, MD, professor of medicine at Weill Cornell Medicine, New York, and chair of the 2023 Lymphoma, Leukemia, and Myeloma Congress.
Dr. Amengual disclosed ties with Astra Zeneca and Incyte. Dr. Westin reported ties with Abbie, ADC therapeutics, AstraZeneca, Bristol-Myers Squibb, Genentech, GenMad, Hanssen, Kite/Gilead, Morphosys/Incyte, Novartis, Nurix, Regeneron, and SeaGen. Dr. Coleman had no disclosures.

The fact that they could come right off the shelf, rather than having to be tailor made for each patient, gives them a huge advantage in terms of cost and availability, while maintaining what appears to be an excellent safety profile” said Morton Colman, MD, professor of medicine at Weill Cornell Medicine, New York, and chair of the 2023 Lymphoma, Leukemia, and Myeloma Congress.
Dr. Amengual disclosed ties with Astra Zeneca and Incyte. Dr. Westin reported ties with Abbie, ADC therapeutics, AstraZeneca, Bristol-Myers Squibb, Genentech, GenMad, Hanssen, Kite/Gilead, Morphosys/Incyte, Novartis, Nurix, Regeneron, and SeaGen. Dr. Coleman had no disclosures.
NEW YORK – according to evidence presented at the 2023 Lymphoma, Leukemia, and Myeloma Congress.
DLBCL is characterized by the National Institutes of Health as an aggressive malignancy and the most common lymphoma. Research presented at the conference indicated that 60%70% of patients were cured with six to eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP).
“In the past, if a relapsed of refractory DLBCL patient couldn’t get a transplant, they were likely headed for palliative care. CAR T-cell therapy is no longer experimental. Not only can we offer it to patients who are ineligible for transplant (and manage the side effects), the treatment has proven to offer better overall survival and cure rates, even in patients who eligible for ASCT,” said presenter Jason Westin, MD, director of the lymphoma clinical research program at the University of Texas MD Anderson Cancer Center, Houston.
The ZUMA-7 phase 3trial among patients with early r/r DLBCL demonstrated the superiority of CAR T-cell therapy with the agent, axicabtagene ciloleucel (YESCARTA, Kita Pharma) versus standard of care (chemoimmunotherapy followed by high-dose chemotherapy and ASCT). Those in the axicabtagene ciloleucel (axi-cel) group had a median progression free survival (PFS) of 14.7 months and an estimated 4-year overall survival (OS) rate of 54.6% compared to 3.7 months and 46% in the control group.
Patients treated with axi-cel experienced a higher rate of adverse events (AE) grade 3 of higher, compared with the ACST group (91% vs. 83%) Furthermore, patients who received axi-cel had cytokine release syndrome (6%) and neurologic events in (21%) grade 3 or higher, compared with 0% and less than 1% in the ASCT group.
At the conference, Dr. Westin’s copanelist Jennifer Amengual, MD, of Columbia University Irving Medical Center, New York, interpreted the data on adverse events (AEs) from ZUMA-7 to mean that if a patient is especially susceptible to CAR T side effects, then ASCT could be preferred. She also outlined a second strategy that shows promise when a patient has either failed CAR T and ASCT or whose frailty demands an approach that avoids AEs.
Dr. Amengual cited a study in which patients with r/r DLBCL were treated with the bispecific antibody glofitamab (Columvi/Roche), which induced a complete response in 39% of patients at a median follow-up of 12.6 months and a 12-month PFS rate of 37%. Those treated with the agent experienced cytokine release syndrome and neurologic events grade 3 or higher, at a rate of 4% and 3% respectively.

Second pig heart recipient dies
the University of Maryland Medical Center (UMMC), Baltimore, reported in a statement.
Mr. Faucette, a former lab tech who was turned down repeatedly for a standard allograft transplantation because of his various medical conditions, received the pig heart transplant on Sept. 20, 2023.
He first came to UMMC as a patient on Sept. 14. When he was admitted, he was in end-stage heart failure. Shortly before the surgery, his heart stopped, and he required resuscitation.
On Sept. 15, the Food and Drug Administration granted an emergency authorization for the surgery through its single-patient investigational new drug compassionate use pathway.
“My only real hope left is to go with the pig heart, the xenotransplant,” Mr. Faucette said in an interview from his hospital room a few days before his surgery. “At least now I have hope, and I have a chance.” He made “significant progress” in the month after the surgery, participating in physical therapy and spending time with family, according to the university. But in the days before his death, the heart showed signs of rejection.
“Mr. Faucette’s last wish was for us to make the most of what we have learned from our experience, so others may be guaranteed a chance for a new heart when a human organ is unavailable,” said Bartley P. Griffith, MD, who transplanted the pig heart into Mr. Faucette at UMMC. “He then told the team of doctors and nurses who gathered around him that he loved us. We will miss him tremendously.”
Muhammad M. Mohiuddin, MD, professor of surgery and scientific/program director of the Cardiac Xenotransplantation Program at the University of Maryland School of Medicine, said that “Mr. Faucette was a scientist who not only read and interpreted his own biopsies, but who understood the important contribution he was making in advancing the field.
“As with the first patient, David Bennett Sr., we intend to conduct an extensive analysis to identify factors that can be prevented in future transplants; this will allow us to continue to move forward and educate our colleagues in the field on our experience,” Dr. Mohiuddin added.
The researchers don’t plan to make further comments until their investigation is complete, a university spokesperson said in an interview.
UMMC performed the first transplant of a genetically modified pig heart in January 2022. Mr. Bennett, the recipient of that heart, survived for 60 days. The researchers published their initial findings in The New England Journal of Medicine, and then the results of their follow-up investigation in The Lancet.

Older adults at risk from inappropriate prescribing
Roughly 2% of prescriptions to older patients appear to be inappropriate – but the figure does not appear to differ between physicians and nurse practitioners, according to a study published in Annals of Internal Medicine.
Older adults are “especially vulnerable to adverse drug events from inappropriate prescribing due to comorbidities and aging-related physiological changes,” said Johnny Huynh, MA, doctoral candidate in economics at UCLA and lead author of the study. “Considering the volume of prescriptions for older adults, even a small percentage can translate to a big impact on adverse drug events and spending.”
In recent years, more states have granted prescriptive authority to NPs, while professional medical organizations have opposed the reforms and made claims about differences in quality of care.
The medical community must focus on the prescribing performance of individual clinicians rather than whether an NP has prescriptive authority, said David Studdert, LLB, ScD, MPH, professor of health policy at Stanford (Calif.) University and a co-author of the study.
“Don’t fixate on whether nurse practitioners have prescriptive authority or don’t,” said Mr. Studdert. “Just try to identify those practitioners who need to boost their performance.”
The investigators found that rates of potentially inappropriate prescribing were “virtually identical.” Adjusted rates were 1.66 per 100 prescriptions for NPs versus 1.68 per 100 prescriptions for physicians (adjusted odds ratio, 0.99; 95% confidence interval, 0.97-1.01).
“Older adults often have more than one chronic condition and are prescribed multiple medications to manage these conditions, putting them at risk for adverse events,” said Paula Rochon, MD, MPH, founding director of the Women’s Age Lab and professor in the Division of Geriatric Medicine at Dalla Lana School of Public Health in Toronto. “Furthermore, older women are more likely than men to have multiple medical problems and experience adverse drug events.”
Dr. Rochon led a 2021 research review on polypharmacy and inappropriate prescribing among older adults in both the United States and abroad. She and her team noted that while women are physiologically more susceptible to drug-related harm, rates of inappropriate prescribing also tend to be higher for women, such as in the case of senior U.S. veterans and older adults in Canada.
The researchers analyzed data over a 7-year period starting in 2013 from 23,669 primary care NPs and 50,060 physicians who wrote prescriptions for at least 100 patients with Medicare Part D coverage. Data from 29 states, which had all expanded prescriptive authority to NPs, was included.
Prescriptive quality was defined by the American Geriatrics Society’s Beers Criteria, a list of potentially inappropriate medications (PIMs) for adults ages 65 and over. Mr. Studdert said it’s important to note the nuance in the Beers Criteria.
“It’s not to say that there may not be certain clinical circumstances where it’s appropriate to” prescribe these drugs, Mr. Studdert said, “But generally, it’s not appropriate.”
Ten medications accounted for 99.5% of the PIMs prescribed, including drugs that were antidepressants, muscle relaxants, hypnotics, antihistamines (generation 1), antispasmodics, sulfonylureas, barbiturates, antineoplastics, thyroid medications, and nonsteroidal anti-inflammatory drugs.
The top three most frequently potentially inappropriately prescribed were antidepressants (0.393 NPs vs. 0.481 PCPs per 100 prescriptions), muscle relaxants (0.372 NPs vs. 0.305 PCPs per 100), and hypnotics (0.364 NPs vs. 0.440 PCPs per 100). Both antidepressants and hypnotics are associated with an increased risk for falls and fractures among older adults, while muscle relaxants have been shown to increase the risk for hospitalization in this population.
Despite the overall similar PIM rates, NPs were more present in the “tails,” or highest and lowest end of the quality bell curve. The higher variation among NPs means these patients are at a higher risk of receiving a prescription for an inappropriate medication, said David Chan, MD, PhD, associate professor of health policy at Stanford (Calif.) School of Medicine, and a co-author of the study.
Other studies have shown “high-intensity prescribers” were more likely to dispense drugs like benzodiazepines and opioids, which can be harmful to older patients.
According to Dr. Rochon, clinicians should use the Beers Criteria and STOPP/START Criteria to guide decision-making, along with the DRUGS framework, which follows a geriatric medicine approach that advises clinicians to discuss goals of care with their patients and conduct routine reviews of medications.
Prescribers should also avoid prescribing cascades, which “occur when a drug is prescribed, an adverse event occurs that is misinterpreted as a new medical condition, and a further drug is prescribed to treat that medical condition,” Dr. Rochon said.
To reduce cascades, “it’s important to document when a medication was started, why it was started, and who started it so that this information is available when evaluating if a medication continues to be needed,” she said.
The study was funded by grants from Robert Wood Johnson Foundation and National Science Foundation. The authors report no relevant financial relationships.

Older adults are “especially vulnerable to adverse drug events from inappropriate prescribing due to comorbidities and aging-related physiological changes,” said Johnny Huynh, MA, doctoral candidate in economics at UCLA and lead author of the study. “Considering the volume of prescriptions for older adults, even a small percentage can translate to a big impact on adverse drug events and spending.”
In recent years, more states have granted prescriptive authority to NPs, while professional medical organizations have opposed the reforms and made claims about differences in quality of care.
The medical community must focus on the prescribing performance of individual clinicians rather than whether an NP has prescriptive authority, said David Studdert, LLB, ScD, MPH, professor of health policy at Stanford (Calif.) University and a co-author of the study.
“Don’t fixate on whether nurse practitioners have prescriptive authority or don’t,” said Mr. Studdert. “Just try to identify those practitioners who need to boost their performance.”
The investigators found that rates of potentially inappropriate prescribing were “virtually identical.” Adjusted rates were 1.66 per 100 prescriptions for NPs versus 1.68 per 100 prescriptions for physicians (adjusted odds ratio, 0.99; 95% confidence interval, 0.97-1.01).
“Older adults often have more than one chronic condition and are prescribed multiple medications to manage these conditions, putting them at risk for adverse events,” said Paula Rochon, MD, MPH, founding director of the Women’s Age Lab and professor in the Division of Geriatric Medicine at Dalla Lana School of Public Health in Toronto. “Furthermore, older women are more likely than men to have multiple medical problems and experience adverse drug events.”
Dr. Rochon led a 2021 research review on polypharmacy and inappropriate prescribing among older adults in both the United States and abroad. She and her team noted that while women are physiologically more susceptible to drug-related harm, rates of inappropriate prescribing also tend to be higher for women, such as in the case of senior U.S. veterans and older adults in Canada.
The researchers analyzed data over a 7-year period starting in 2013 from 23,669 primary care NPs and 50,060 physicians who wrote prescriptions for at least 100 patients with Medicare Part D coverage. Data from 29 states, which had all expanded prescriptive authority to NPs, was included.
Prescriptive quality was defined by the American Geriatrics Society’s Beers Criteria, a list of potentially inappropriate medications (PIMs) for adults ages 65 and over. Mr. Studdert said it’s important to note the nuance in the Beers Criteria.
“It’s not to say that there may not be certain clinical circumstances where it’s appropriate to” prescribe these drugs, Mr. Studdert said, “But generally, it’s not appropriate.”
Ten medications accounted for 99.5% of the PIMs prescribed, including drugs that were antidepressants, muscle relaxants, hypnotics, antihistamines (generation 1), antispasmodics, sulfonylureas, barbiturates, antineoplastics, thyroid medications, and nonsteroidal anti-inflammatory drugs.
The top three most frequently potentially inappropriately prescribed were antidepressants (0.393 NPs vs. 0.481 PCPs per 100 prescriptions), muscle relaxants (0.372 NPs vs. 0.305 PCPs per 100), and hypnotics (0.364 NPs vs. 0.440 PCPs per 100). Both antidepressants and hypnotics are associated with an increased risk for falls and fractures among older adults, while muscle relaxants have been shown to increase the risk for hospitalization in this population.
Despite the overall similar PIM rates, NPs were more present in the “tails,” or highest and lowest end of the quality bell curve. The higher variation among NPs means these patients are at a higher risk of receiving a prescription for an inappropriate medication, said David Chan, MD, PhD, associate professor of health policy at Stanford (Calif.) School of Medicine, and a co-author of the study.
Other studies have shown “high-intensity prescribers” were more likely to dispense drugs like benzodiazepines and opioids, which can be harmful to older patients.
According to Dr. Rochon, clinicians should use the Beers Criteria and STOPP/START Criteria to guide decision-making, along with the DRUGS framework, which follows a geriatric medicine approach that advises clinicians to discuss goals of care with their patients and conduct routine reviews of medications.
Prescribers should also avoid prescribing cascades, which “occur when a drug is prescribed, an adverse event occurs that is misinterpreted as a new medical condition, and a further drug is prescribed to treat that medical condition,” Dr. Rochon said.
To reduce cascades, “it’s important to document when a medication was started, why it was started, and who started it so that this information is available when evaluating if a medication continues to be needed,” she said.
The study was funded by grants from Robert Wood Johnson Foundation and National Science Foundation. The authors report no relevant financial relationships.

Omitting surgery may be safe in early BC after neoadjuvant pCR
A small trial headed by MD Anderson Cancer Center, Houston, has helped to further identify women who can safely skip surgery after neoadjuvant therapy for early breast cancer.
Among 50 women in the study with cT1-2N0-1M0 triple negative or HER2-positive disease, 31 (62%) had a complete pathologic response (pCR) to neoadjuvant therapy on image-guided vacuum-assisted core biopsy (VACB).
They went onto whole breast radiation with a boost, but given their response to neoadjuvant treatment and the accuracy of VACB, the women did not have surgery.
So far, it seems to have been the right call: At 3 years, there’s been no tumor recurrences and disease-free and overall survival are both 100%.
Eliminating “breast surgery in highly-selected patients with image-guided VACB-determined pCR following” neoadjuvant systemic therapy has “very promising 3-year results,” lead investigator Henry M. Kuerer, MD, PhD, a breast cancer surgeon at MD Anderson, who presented the findings at the European Society for Medical Oncology (ESMO) 2023 annual meeting.
With the success of modern systemic therapy, “it’s only natural that we think this way,” said Ava Kwong, PhD, chief of breast surgery at the University of Hong Kong, who discussed Dr. Kuerer’s presentation at the meeting.
“This study is really important,” she said. “It’s addressing a very important question whether we can omit surgery in certain groups of patients ... We do want to deescalate surgery,” and the study results are “very good,” she said.
However, larger trials with longer follow-up are needed to draw any firm conclusions, she said.
Dr. Kuerer agreed. He and his team will continue to follow the study subjects, and they have opened up a new trial with 100 patients. A similar study is ongoing in Korea, as well, he noted.
Study details
Women in the trial were a median of 60.4 years old; 58% had HER2-positive and the rest triple-negative unicentric breast cancer. Mean baseline tumor size was 2.8 cm. Just 12% of the participants had lymph node involvement. Neoadjuvant systemic therapy was clinician’s choice.
Breast lesions had to shrink to less than 2 cm on imaging after systemic therapy to be eligible for the study, and a minimum of 12 cores had to be obtained on VACB.
The 38% of women in the study with residual disease after systemic treatment went on to surgery.
Two patients were circulating tumor cell (CTC)-positive at baseline, two were positive at 6 months, and one at 12 months. No patients had CTCs detected at more than one timepoint.
The work was funded by the National Cancer Institute. Dr. Kuerer is an adviser for Merck. Dr. Kwong is an adviser/speaker/reviewer/author for Stryker, AstraZeneca, Merck, and Roche. She also disclosed research funding from Merck, Roche, and Gilead and funding for genetic testing from AstraZeneca.

Gut microbiome variations may be predictive of precancerous colonic lesions, CRC
COPENHAGEN – according to a large, 22-year analysis from the Dutch Microbiome Project cohort study.
The findings suggest a possible role for gut microbiota in the development of colorectal lesions and cancer, said study lead Ranko Gacesa, PhD, from the department of gastroenterology, University of Groningen (the Netherlands), who presented the results at the annual United European Gastroenterology Week.
“It [also] suggests that gut bacteria might enhance currently used noninvasive fecal tests for the detection of colorectal polyps, and even that microbiome-modulating therapies might play a role in prevention of colorectal cancer,” said Dr. Gacesa, who won the award for best abstract in the meeting session.
The gut microbiome is known to be linked to colorectal cancer (CRC); in particular, the bacteria Bacteroides fragilis and Alistipes finegoldii have been found to cause CRC in mouse models, explained Dr. Gacesa.
In the current study, Dr. Gacesa and colleagues looked at the potential for the gut microbiome in humans to play a role in the detection of precancerous colonic lesions. The noninvasive fecal immunochemical test (FIT), recently shown to be a preference among patients, produces a high number of false-positive results, leading to many unnecessary colonoscopies.
“It has been calculated that the use of a fecal microbiota analysis combined with FIT in the early-stage prediction of CRC could result in a high true-positive rate and a low false-positive rate,” said Dr. Gacesa. “In this way, we might reduce the false-positive rate by around 50%.
“Ideally, we don’t want to detect cancer when it is already established and is hard to treat. We want to detect it as early in its development as possible,” he said.
Longitudinal analysis using large Dutch databases
To determine the direction of the relationship between CRC and the gut microbiome, the Dutch researchers conducted a longitudinal analysis from 2000 to 2022, looking at whether CRC alters the gut microbiome, as well as whether changes in the microbiome contribute to the development of precancerous lesions and CRC.
They drew on data from the Dutch colorectal cancer screening program, comprising FIT results in people aged 55 years and older, and colonoscopy if referred. They recorded cases of colonic biopsies from the extensive Dutch national database of medical biopsies. These were then linked with Dutch microbiome project data sourced from fecal samples of 8208 individuals taken between 2012 and 2015.
“This allowed us to associate gut microbiome compositions and functions to detailed histological information about precancerous lesions and CRC, including when lesions were detected relative to fecal sampling [and a reading of the gut microbiome],” Dr. Gacesa explained.
The analysis determined the composition, function, and genomic profiles of gut microbiota in participants who developed precancerous colorectal lesions before fecal sampling from 2000 to 2015, and in those participants who developed lesions after fecal sampling, between 2015 and 2022. Clinical phenotypes, comprising the type and size of lesions, were noted. The control group included 2123 individuals from the general population with normal colonoscopy findings.
More precancerous lesions found after fecal sampling
There were more cases of precancerous lesions found after fecal sampling, reported Dr. Gacesa.
Before fecal sampling, 219 participants had colonic lesions, including low-grade dysplasia, high-grade dysplasia, and serrated polyps, and 26 cases of CRC. A total of 315 participants developed assorted colonic lesions after fecal sampling, with a total of 29 cases of CRC.
When the researchers looked at microbiome diversity in people who had experienced precancerous colonic lesions 1-5 years before fecal sampling, they found that diversity was lower, compared with controls. Microbiome diversity was also decreased in participants who developed colonic lesions after sampling.
The microbiome composition and function were different between patients with preexisting and future lesions, and varied based on the types of lesion.
“We saw a drop in some commensal bacteria, including Faecalibacterium, in both those with recent pathologies and those who developed them in the future. We also saw a massive spike in Alistipes finegoldii in those who had CRC, strongly suggesting it is closely linked to CRC in people,” reported Dr. Gacesa.
Among bacterial species linked with the future development of precancerous lesions were those from the family of Lachnospiraceae, and the genera Roseburia and Eubacterium. Microbiome composition had a moderate predictive power for future lesions and CRC.
“Precancerous lesions are linked to the gut microbiome,” Dr. Gacesa said. “Adenomas – both preexisting ones (before fecal sampling), and ones that came after fecal sampling – are significantly linked to the microbiome composition.”
More time needed
Loris Lopetuso, MD, gastroenterologist, from Fondazione Policlinico Universitario Agostino Gemelli, Rome, who comoderated the session, remarked that the data were intriguing and important.
“We really need to find new predictors of tumorigenesis,” he said. “We already have some good predictors, mainly FIT, but these are not enough. These gut microbiota look promising.”
He added that the study by Dr. Gacesa’s team was one of the largest he had seen. “But I would note that, methodologically, we need to remember that the time between a fecal sample and the development of polyps can be very large,” Dr. Lopetuso emphasized. “This study looked at around 5 years only. Also, the microbiota can change from one day to the other in response to stress, diet, and many other things.”
However, “this could be the beginning of a longitudinal study between cases and controls because many years are needed,” he added.
Dr. Gacesa has received funding from Janssen Pharmaceuticals for an unrelated research project. He is a paid R&D consultant for Esox Biologics Ltd for topics unrelated to this project. Dr. Lopetuso reported no relevant financial relationships.
