Child abuse visits to EDs declined in 2020, but not admissions
but the visits in 2020 were significantly more likely to result in hospitalization, based on analysis of a national ED database.
The number of ED visits involving child abuse and neglect was down by 53% during the 4-week period from March 29 to April 25, 2020, compared with the 4 weeks from March 31 to April 27, 2019. The proportion of those ED visits that ended in hospitalizations, however, increased from 2.1% in 2019 to 3.2% in 2020, Elizabeth Swedo, MD, and associates at the Centers for Disease Control and Prevention said in the Morbidity and Mortality Weekly Report.
“ED visits related to suspected or confirmed child abuse and neglect decreased beginning the week of March 15, 2020, coinciding with the declaration of a national emergency related to COVID-19 and implementation of community mitigation measures,” they wrote.
An earlier study involving the same database (the National Syndromic Surveillance Program) showed that, over the two same 4-week periods, the volume of all ED visits in 2020 was down 72% for children aged 10 years and younger and 71% for those aged 11-14 years.
In the current study, however, all age subgroups had significant increases in hospital admissions. The proportion of ED visits related to child abuse and neglect that resulted in hospitalization rose from 3.5% in 2019 to 5.3% in 2020 among ages 0-4 years, 0.7% to 1.3% for ages 5-11 years, and 1.6% to 2.2% for adolescents aged 12-17, Dr. Swedo and associates reported.
The absence of a corresponding drop in hospitalizations may be tied to risk factors related to the pandemic, “such as loss of income, increased stress related to parental child care and schooling responsibilities, and increased substance use and mental health conditions among adults,” the investigators added.
The National Syndromic Surveillance Program receives daily data from 3,310 EDs in 47 states, but the number of facilities meeting the investigators’ criteria averaged 2,970 a week for the 8 weeks of the study period.

FDA OKs osimertinib as first adjuvant drug for NSCLC
Osimertinib was first approved in the US in 2018 for the first-line treatment of patients with metastatic EGFR-mutated NSCLC.
With this new indication, “patients may be treated with this targeted therapy in an earlier and potentially more curative stage of non-small cell lung cancer,” Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research, said in a news release.
The expanded indication is based on results of the ADAURA clinical trial, which compared osimertinib with placebo following complete resection of localized or locally advanced NSCLC with negative margins.
In the trial, adjuvant osimertinib reduced the relative risk of disease recurrence or death by 83% in patients with stage II and IIIA disease (hazard ratio [HR], 0.17; 95% CI, 0.12 - 0.23; P < .0001).
Disease-free survival (DFS) in the overall trial population of patients with stage IB-IIIA disease showed osimertinib reduced the risk of disease recurrence or death by 80% (HR, 0.20; 95% CI, 0.15 - 0.27; P < .0001).
At 2 years, 89% of patients treated with the targeted agent remained alive and disease free vs 52% on placebo after surgery. The safety and tolerability of osimertinib in the adjuvant setting was consistent with previous trials in the metastatic setting.
The trial of 682 patients was unblinded early and halted on the recommendation of the independent data-monitoring committee, because of the efficacy of osimertinib.
“If I were on the committee, I would have done the same thing. These are extraordinary results,” study investigator Roy S. Herbst, MD, PhD, chief of medical oncology at the Yale Cancer Center, New Haven, Connecticut, said at a press briefing prior to the study presentation at the American Society of Clinical Oncology’s (ASCO) virtual scientific program last spring.
In a Medscape commentary, Mark Kris, MD, of Memorial Sloan Kettering Cancer Center in New York City, said the data with osimertinib in the adjuvant setting are “important and practice-changing.”
“The potential for this drug to improve outcomes has been there for a long time. This phase 3 randomized trial presented at the plenary session of ASCO showed a more than doubling of disease-free survival at 2 years. It shows that we can use therapies in the earlier stages of disease,” Kris noted.
“This approval dispels the notion that treatment is over after surgery and chemotherapy, as the ADAURA results show that Tagrisso can dramatically change the course of this disease,” Dave Fredrickson, executive vice president, AstraZeneca oncology business unit, said in a news release.
Osimertinib had orphan drug status and breakthrough therapy designation for treatment of EGFR mutation-positive NSCLC.

FDA OKs first oral hormone therapy for advanced prostate cancer
Relugolix is an oral gonadotropin-releasing hormone antagonist. The new pill form may mean fewer clinic visits for patients, an added benefit during the COVID-19 pandemic, said Richard Pazdur, MD, acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research, in a press statement.
“Today’s approval marks the first oral drug in this class, and it may eliminate some patients’ need to visit the clinic for treatments that require administration by a health care provider,” he commented.
Relugolix works by preventing the pituitary gland from making luteinizing hormone and follicle-stimulating hormone, thus reducing the amount of testosterone the testicles can make.
In the open-label HERO trial, 930 patients with locally advanced or metastatic prostate cancer were randomly assigned to receive either once-daily oral relugolix or leuprolide injection every 3 months for 48 weeks.
The study met its primary endpoint, demonstrating that castration at 48 weeks was maintained in 96.7% of men receiving relugolix vs. 88.8% for patients receiving leuprolide; castration levels of testosterone had to be reached by day 29 and then sustained through the end of the treatment course.
Relugolix has the “potential to become a new standard for ADT and advanced prostate cancer,” commented study investigator Neal D. Shore, MD, of Carolina Urologic Research Center, Myrtle Beach, South Carolina, at the 2020 annual meeting of the American Society of Clinical Oncology, where the results were first presented.
They were published simultaneously in The New England Journal of Medicine.
At the ASCO meeting, David R. Wise, MD, PhD, Perlmutter Cancer Center at NYU Langone Health, New York, agreed that the drug could be practice-changing – but claimed that it would be for a subset of patients only, specifically, patients with a significant history of cardiovascular disease who are without gastrointestinal malabsorption.
Notably, in the study, relugolix cut the risk for major adverse cardiovascular events by 54% in comparison with leuprolide, as reported by Medscape Medical News.
According to the FDA, the most common side effects of relugolix include hot flush, increased glucose levels, increased triglyceride levels, musculoskeletal pain, decreased hemoglobin, fatigue, constipation, diarrhea, and increased levels of certain liver enzymes.
Concurrent use of relugolix with drugs that inhibit P-glycoprotein is contraindicated.
Also, health care providers should consider having patients undergo periodic electrocardiographic monitoring as well as periodic monitoring of electrolyte levels. Owing to the drug’s suppression of the pituitary gonadal system, any diagnostic test results of the pituitary gonadotropic and gonadal functions conducted during and after taking relugolix may be affected.

FDA expands belimumab indication to adults with lupus nephritis
The U.S. Food and Drug Administration has expanded the indication for belimumab (Benlysta) to adults with active lupus nephritis who are receiving standard therapy.
Roughly 40% of patients with systemic lupus erythematosus (SLE) develop lupus nephritis (LN), which causes inflammation in the kidneys and can lead to end-stage kidney disease.
“Benlysta is the first medicine approved to treat systemic lupus and adults with active lupus nephritis, an important treatment advance for patients with this incurable autoimmune disease,” Hal Barron, MD, GlaxoSmithKline’s chief scientific officer and president of research and development, said in a company news release.
Belimumab IV infusion was first approved in the United States in March 2011 for adults with SLE. The FDA approved belimumab IV infusion for use in children as young as age 5 years with SLE in 2019.
Both the IV and subcutaneous formulations are now indicated in the United States for adults with SLE and LN.
Belimumab is a B-lymphocyte stimulator protein inhibitor that is thought to decrease the amount of abnormal B cells; the latter are thought to play a role in lupus.
The expanded indication for belimumab for patients with LN is based on findings from the BLISS-LN phase 3 trial, published in The New England Journal of Medicine in September.
“Neutralizing B-cell activating factor and down-regulating autoreactive B-cell function in kidneys” represents a “compelling therapeutic approach to lupus nephritis,” the lead investigator of BLISS-LN, Richard Furie, MD, told the online annual Perspectives in Rheumatic Diseases meeting recently.
“In the 4 decades I have been caring for people with lupus, we have not been able to achieve remission in more than just one-third of patients with lupus nephritis, and despite all of our efforts, 10%-30% of patients with lupus kidney disease still progress to end-stage kidney disease,” Dr. Furie, who is chief of the division of rheumatology at Northwell Health, notes in the GSK statement.
“The data from the BLISS-LN study show that Benlysta added to standard therapy not only increased response rates over 2 years, but it also prevented worsening of kidney disease in patients with active lupus nephritis, compared to standard therapy alone,” he added.
BLISS-LN study: Belimumab effect seen mostly in those on MMF
BLISS-LN enrolled 448 adults with biopsy-confirmed active LN. Half were randomly allocated to receive IV belimumab (10 mg/kg) plus standard therapy (mycophenolate mofetil for induction and maintenance or cyclophosphamide for induction followed by azathioprine for maintenance, with steroids) and half to receive placebo plus standard therapy.
At 2 years, significantly more patients in the belimumab group than in the placebo group had a primary efficacy renal response (43% vs. 32%; odds ratio, 1.6; 95% confidence interval, 1.0- 2.3; P = .03).
This primary endpoint was defined as a ratio of urinary protein to creatinine of ≤0.7, an estimated glomerular filtration rate that was no worse than 20% below the value before the renal flare or ≥60 mL per minute per 1.73 m2 of body surface area, without use of rescue therapy.
The risk for a renal-related event or death was also significantly lower among patients who received belimumab than among those who received placebo (hazard ratio, 0.51; P = .001). The safety profile of belimumab was consistent with that observed in prior studies.
But in a commentary that accompanied the publication of BLISS-LN, editorialists noted that “most of the treatment effect was seen in patients who had received mycophenolate mofetil. No benefit was present in the subgroup of patients who received cyclophosphamide-azathioprine.”
In addition, induction treatment was not randomly assigned, editorialists Michael Ward, MD, MPH, and Maria Tektonidou, MD, PhD, noted.
“If patients with more severe nephritis were preferentially treated with cyclophosphamide, a likely inclination among most physicians, the trial may be telling us that belimumab enhances responses only among less severely affected patients,” observed Dr. Ward, who is with the National Institutes of Health, and Dr. Tektonidou, of the National and Kopodistrian University, in Athens.

BLISS-LN enrolled 448 adults with biopsy-confirmed active LN. Half were randomly allocated to receive IV belimumab (10 mg/kg) plus standard therapy (mycophenolate mofetil for induction and maintenance or cyclophosphamide for induction followed by azathioprine for maintenance, with steroids) and half to receive placebo plus standard therapy.
At 2 years, significantly more patients in the belimumab group than in the placebo group had a primary efficacy renal response (43% vs. 32%; odds ratio, 1.6; 95% confidence interval, 1.0- 2.3; P = .03).
This primary endpoint was defined as a ratio of urinary protein to creatinine of ≤0.7, an estimated glomerular filtration rate that was no worse than 20% below the value before the renal flare or ≥60 mL per minute per 1.73 m2 of body surface area, without use of rescue therapy.
The risk for a renal-related event or death was also significantly lower among patients who received belimumab than among those who received placebo (hazard ratio, 0.51; P = .001). The safety profile of belimumab was consistent with that observed in prior studies.
But in a commentary that accompanied the publication of BLISS-LN, editorialists noted that “most of the treatment effect was seen in patients who had received mycophenolate mofetil. No benefit was present in the subgroup of patients who received cyclophosphamide-azathioprine.”
In addition, induction treatment was not randomly assigned, editorialists Michael Ward, MD, MPH, and Maria Tektonidou, MD, PhD, noted.
“If patients with more severe nephritis were preferentially treated with cyclophosphamide, a likely inclination among most physicians, the trial may be telling us that belimumab enhances responses only among less severely affected patients,” observed Dr. Ward, who is with the National Institutes of Health, and Dr. Tektonidou, of the National and Kopodistrian University, in Athens.

Margetuximab approved for HER2-positive metastatic breast cancer
The new drug is indicated for use in combination with chemotherapy for the treatment of patients with metastatic HER2-positive breast cancer who have already received two or more prior anti-HER2 regimens, with at least one for metastatic disease.
Margetuximab-cmkb is also the first HER2-targeted therapy shown to improve progression-free survival (PFS) as compared with the first-ever HER2-targeted agent, trastuzumab in a head-to-head, phase 3 clinical trial (known as SOPHIA).
“Early detection and treatment have had a positive impact on the survival of patients with breast cancer, but the prognosis for people diagnosed with metastatic breast cancer remains poor, and additional treatments are needed,” said Hope S. Rugo, MD, director of breast oncology and clinical trials education, University of California, San Francisco, Diller Family Comprehensive Cancer Center, in a press release.
“As the only HER2-targeted agent to have shown a PFS improvement versus trastuzumab in a head-to-head phase 3 clinical trial, margetuximab with chemotherapy represents the newest treatment option for patients who have progressed on available HER2-directed therapies,” said Dr. Rugo, who is an investigator in the SOPHIA trial.
Like trastuzumab, margetuximab-cmkb binds HER2 with high specificity and affinity and disrupts signaling that drives cell proliferation and survival, but margetuximab binds with elevated affinity to both the lower- and higher-affinity forms of CD16A, an Fc gamma receptor important for antibody dependent cell-mediated cytotoxicity against tumor cells, according to the manufacturer, MacroGenics.
Details of the pivotal trial
The SOPHIA trial was a randomized, open-label, phase 3 clinical trial that compared margetuximab-cmkb plus chemotherapy with trastuzumab plus chemotherapy in both arms in patients with HER2-positive metastatic breast cancer who had previously been treated with anti–HER2-targeted therapies.
All patients in the cohort had previously received trastuzumab, all but one patient had previously also received pertuzumab, and most of the patients (91%) had also been treated with ado-trastuzumab emtansine, or T-DM1.
The trial randomly assigned 536 patients to receive either margetuximab-cmkb (n = 266) given intravenously at 15 mg/kg every 3 weeks or trastuzumab (n = 270) given intravenously at 6 mg/kg (or 8 mg/kg for loading dose) every 3 weeks in combination with either capecitabine, eribulin, gemcitabine, or vinorelbine, given at the standard doses.
As compared with trastuzumab, margetuximab plus chemotherapy led to a significant 24% reduction in the risk for progression or death (hazard ratio, 0.76).
The median PFS also favored margetuximab (5.8 months vs. 4.9 months), as did the overall response rate (22% vs. 16%).
The final overall survival analysis is expected in the second half of 2021.
Common adverse events associated with the margetuximab regimen included fatigue/asthenia (57%), nausea (33%), diarrhea (25%), and vomiting (21%). Infusion-related reactions occurred in 13% of patients receiving margetuximab, and almost all were grade 1 or 2, with only 1.5% at grade 3.
The product also carries a boxed warning for left ventricular dysfunction and embryo-fetal toxicity.

Vaccine rollout on track, expect 300 million doses through March: Feds
If the initial success of the Pfizer-BioNTech rollout continues, and emergency use authorization (EAU) is granted to Moderna and Johnson & Johnson vaccines in development, Operation Warp Speed officials expect to have 300 million doses of COVID-19 vaccines to distribute across the United States between now and March 31.
The initial rollout remains on track, said Alex Azar, US Department of Health and Human Services (HHS) secretary, during a media briefing today. “We continue to have good news to report. As of today, shipments of vaccine will have been delivered to every delivery site identified by public health jurisdictions for our first wave of shipments.”
Anomalies in shipments to California and Alabama arose when temperature monitors showed the Pfizer vaccine dropped lower than the recommended -80 ºC (-112 °F). These vaccine trays remained on delivery trucks and were returned to Pfizer for prompt replacement, said Operation Warp Speed Chief Operating Officer Gen. Gustave F. Perna.
Azar estimated another 2 million doses of the Pfizer vaccine will be available next week. “And if the Moderna vaccine is authorized by the FDA in the coming days, we have allocated nearly 5.9 million doses of that product.”
The Moderna vaccine data released this week look promising, said Moncef Slaoui, PhD, Operation Warp Speed chief scientific adviser. “In the short term, I expect the protection to be quite significant.”
The findings in the first 2 weeks after the first dose show up to 65% protection, he said, and predicted the second-dose efficacy data will be coming in the next few weeks.
Enrollment in the phase 3 Johnson & Johnson trial with nearly 44,000 participants is expected to end December 17. Initial efficacy results are anticipated by early January, with more complete efficacy numbers by late January, Slaoui said.
The AstraZeneca COVID-19 vaccine trial also is underway with enrollment continuing. “We expect accruement to end in late December or early next year, with first results expected probably in February,” Slaoui said.
Antibody treatments underutilized
The media briefing also addressed COVID-19 therapeutics. Azar reported low uptake of available antibody therapies. “I want to remind Americans that there are two authorized antibody treatments that Operation Warp Speed has supported. They can help prevent hospitalization in those patients with the highest risk for severe disease.”
The higher-risk group includes those who are 65 and older and people with comorbid conditions that put them at increased risk for COVID-19 hospitalization.
The federal government allocated more than 330,000 doses of these treatments and many states have product available, Azar said.
Slaoui agreed, saying there is a “disappointing level of usage of monoclonal antibody therapy in hospitals. We look forward to that improving.”
Up to 3 billion vaccine doses possible
“We now have more than 900 million doses of the vaccine we have contracted delivery for,” Azar said. The government has options to increase that to a total of 3 billion doses.
In addition to the 100 million Pfizer vaccine doses and 100 million Moderna doses already ordered, the government just took an option for another 100 million Moderna doses for the second quarter of 2021. Operation Warp Speed officials are negotiating with Pfizer for additional product as well.
Azar added that there are 100 million doses of the Johnson & Johnson vaccine in active production and expects AstraZeneca can provide 300 million doses of their product.
With the possibility of three or more vaccine products and with 330 million Americans, minus the 70 million or so children under age 16, “we believe we will actually have surplus supplies,” Azar said. Plans are to take the US surplus vaccine and surplus manufacturing capacity “and use that for the benefit of the world community.”

Urgent recall for Penumbra JET 7 Xtra Flex reperfusion catheters
“All users should stop using this device, and facilities should remove these devices from inventory,” the recall notice, posted on the U.S. Food and Drug Administration website, advises.
The recall covers the JET 7 Xtra Flex catheter, which was cleared for use in June 2019, and the JET 7MAX configuration (which includes the JET 7 Xtra Flex catheter and MAX delivery device), which was cleared in February of this year.
The recall does not apply to the Penumbra JET 7 reperfusion catheter with standard tip.
The FDA says it has received over 200 medical device reports (MDRs) associated with the JET 7 Xtra Flex catheter, including reports of deaths, serious injuries, and malfunctions.
Twenty of these MDRs describe 14 unique patient deaths. Other MDRs describe serious patient injury, such as vessel damage, hemorrhage, and cerebral infarction.
Device malfunctions described in the reports include ballooning, expansion, rupture, breakage or complete separation, and exposure of internal support coils near the distal tip region of the JET 7 Xtra Flex catheter.
According to the FDA, bench testing by the manufacturer, in which the catheter distal tip is plugged and pressurized to failure, indicates that the JET 7 Xtra Flex catheter is not able to withstand the same burst pressures to failure as the manufacturer’s other large-bore aspiration catheters used to remove thrombus for patients with acute ischemic stroke.
Penumbra’s urgent medical device recall letter advises health care providers and facilities to remove and quarantine all unused devices covered by this recall, to complete the product identification and return form, and to return all products to Penumbra in accordance with instructions provided.
For questions regarding this recall, contact Penumbra customer service by phone at 888-272-4606 or by email at [email protected].

Parents favored virtual learning over in-person school attendance
Parents of school-aged children were generally more comfortable with full-time virtual learning in schools in the fall of 2020, compared with full-capacity in-person attendance, according to a survey conducted in July.
Those of racial/ethnic minorities, however, “were less likely to feel that schools should reopen for all students and were more concerned about” several aspects of in-person instruction than were White parents, Leah K. Gilbert, MD, and associates at the Centers for Disease Control and Prevention’s COVID-19 Response Team said in the Morbidity and Mortality Weekly Report.
A slim majority, just under 53% of the 858 parents surveyed, said that they were very or somewhat comfortable with their children returning to schools that were reopening at full capacity, while almost 70% said they were very/somewhat comfortable with schools going exclusively with virtual learning, the investigators reported.
The question about full-capacity attendance in particular showed considerable variation by race and ethnicity, with 57% of White parents saying they were very/somewhat comfortable, versus 53% of Hispanic or Latino parents, 43% of Black parents, and 32.5% of parents of other races/ethnicities (American Indian/Alaska Native, Asian, or multiracial).
Comfort levels were closer regarding virtual learning: Parents of other races/ethnicities were lowest at 67% and Black parents were highest at 73%. When asked about schools reopening at 50% capacity and 50% virtual learning, Black parents were again lowest at 58% with strong or moderate comfort and White parents were highest at 68%, Dr. Gilbert and associates said.
“Although the majority of parent respondents had concerns about both school reopening for in-person instruction and virtual learning, the perceived risk for SARS-CoV-2 infection and poor health outcomes might account for the differences in parental attitudes and concerns by race and ethnicity,” they wrote.

FDA safety alert: Face masks with metal can burn during MRI
After a patient’s face was burned in the outline of a mask worn during a 3-Tesla MRI neck scan, the US Food and Drug Administration (FDA) cautioned that face masks containing metal can heat to unsafe temperatures during scanning.
Clinicians have known for years to ask patients to remove all metal jewelry and other objects prior to an MRI. The widespread wearing of face masks during the COVID-19 pandemic, however, adds one more consideration to the list.
The FDA’s December 7 safety communication applies to surgical and nonsurgical face masks and respirators.
The injury risk relates to rapid heating of metal components. Many face masks contain a nose wire or metal clip that helps the product conform to the face. Some masks contain metal nanoparticles, while others feature antimicrobial coatings with silver or copper. Each of these products should be avoided during MRI scanning. Also watch out for staples on headbands, the FDA warned.
If the metal content of a face mask is unknown, the FDA suggests providing the patient with a facial covering that is known not to contain any metal.
Robert E. Watson Jr, MD, PhD, chair of the American College of Radiology (ACR) Committee on MR Safety, agreed. He recommended that facilities “provide patients with masks known to be MRI-safe and not permit patient-owned masks in the MRI.”
Watson suggested this strategy at a time when face masks are required.
“COVID-19 safety protocols require that patients wear masks when being scanned, to decrease infection risk to MRI staff, decrease risk of contaminating the MRI scanner, and to protect themselves from infection,” he told Medscape Medical News. “Any conducting metal that enters the MRI machine is at risk of heating due to the radiofrequency fields inherent to image generation.”
Adverse events related to the metal components of a face mask should be reported to the FDA using the MedWatch voluntary reporting form. In addition, healthcare providers subject to the FDA user facility reporting requirements should follow procedures at their facilities to report such events.

FDA approves first agent for PSMA-PET imaging in prostate cancer
A radioactive diagnostic agent has been approved by the U.S. Food and Drug Administration for use in patients with prostate cancer, but only for those treated at two institutions in California.
The product, Gallium 68 PSMA-11 (Ga 68 PSMA-11), is the first agent approved specifically for use in positron-emission tomography (PET) imaging of prostate-specific membrane antigen (PSMA)–positive lesions in men with prostate cancer, the FDA noted.
This imaging approach can “detect whether or not the cancer has spread to other parts of the body,” commented Alex Gorovets, MD, acting deputy director of the Office of Specialty Medicine in the FDA’s Center for Drug Evaluation and Research.
Ga 68 PSMA-11 is indicated for use in patients with suspected prostate cancer metastasis whose conditions are potentially curable by surgery or radiotherapy and in patients with suspected prostate cancer recurrence, as determined on the basis of elevated serum prostate-specific antigen (PSA) levels.
Institutional use only
Ga 68 PSMA-11 has been approved for institutional use at the University of California, Los Angeles and the University of California, San Francisco under an academic new drug application (NDA).
The FDA approval was based partly on a clinical trial conducted by the UCSF and UCLA research teams on the effectiveness of PSMA-PET.
“It is rare for academic institutions to obtain FDA approval of a drug, and this unique collaboration has led to what is one of the first coapprovals of a drug at two institutions,” said Thomas Hope, MD, an associate professor at UCSF. “We hope that this first step will lead to a more widespread availability of this imaging test to men with prostate cancer throughout the country.”
Ga 68 PSMA-11 was developed outside the United States at the University of Heidelberg (Germany).
A commercial NDA from Telix Pharmaceuticals for TL591-CDx, a radiopharmaceutical cold kit for the preparation of Ga 68 PSMA-11 injection, is under consideration by the FDA.
The agency noted that two other PET diagnostic agents – fluciclovine F18 and choline C11 – are approved for prostate cancer imaging. However, they are only approved for use in patients with suspected cancer recurrence.
Trial results with PSMA-PET/CT
“PSMA-PET/CT is a novel molecular and functional imaging modality specific for prostate cancer cells that has good sensitivity and outstanding specificity in detecting metastasis,” commented T. Martin Ma, MD, PhD, of UCLA.
Dr. Ma presented a U.S. study on the technique at the recent annual meeting of the American Society for Radiation Oncology. That study showed that PSMA-PET/CT led to nodal upstaging in 19.7% of patients and metastasis upstaging in 9.4%.
He said these results were similar to those from the Australian proPSMA trial, which was published in The Lancet earlier this year. That trial found PSMA-PET/CT to be superior to conventional imaging with CT and bone scanning for primary staging of high-risk prostate cancer.
“These findings carry significant clinical implications and can affect treatment decision-making,” Dr. Ma commented.
“PSMA-PET has been a real game changer in high-risk prostate cancer and has implications in the various stages of prostate cancer management from diagnosis and staging to theranostics,” said Renu Eapen, MBBS, of Peter MacCallum Cancer Center, Melbourne, who was not involved in either study.
“PSMA-PET/CT has challenged conventional imaging in staging before curative-intent surgery or radiotherapy,” Dr. Eapen added.
The accuracy of PSMA-PET/CT was 27% higher than that of conventional imaging in the proPSMA trial, she noted in an interview last month. This superior accuracy can ultimately affect management. The imaging has additional benefits of lower radiation dose as well as reproducibility with high reporter agreement, potentially making it a “one-stop-shop” scan.
Trial results with Ga 68 PSMA-11
The safety and efficacy of Ga 68 PSMA-11 were evaluated in two prospective clinical trials with a total of 960 men with prostate cancer, each of whom received one injection of the product.
The first trial involved 325 patients with biopsy-proven prostate cancer who underwent PET/CT or PET/MRI scans performed with Ga 68 PSMA-11.
“These patients were candidates for surgical removal of the prostate gland and pelvic lymph nodes and were considered at higher risk for metastasis. Among the patients who proceeded to surgery, those with positive readings in the pelvic lymph nodes on Ga 68 PSMA-11 PET had a clinically important rate of metastatic cancer confirmed by surgical pathology,” the FDA noted.
“The availability of this information prior to treatment is expected to have important implications for patient care,” the FDA commented. “For example, it may spare certain patients from undergoing unnecessary surgery.”
The second trial enrolled 635 patients with rising serum PSA levels after initial prostate surgery or radiotherapy. All patients received a single Ga 68 PSMA-11 PET/CT scan or PET/MRI scan.
About three-quarters of patients (74%) had at least one positive lesion detected by Ga 68 PSMA-11 PET in at least one region – bone, prostate bed, pelvic lymph node, or extra-pelvic soft tissue.
“In patients with positive Ga 68 PSMA-11 PET readings who had correlative tissue pathology from biopsies, results from baseline or follow-up imaging by conventional methods, and serial PSA levels available for comparison, local recurrence or metastasis of prostate cancer was confirmed in an estimated 91% of cases,” the FDA noted.
“Thus, the second trial demonstrated that Ga 68 PSMA-11 PET can detect sites of disease in patients with biochemical evidence of recurrent prostate cancer, thereby providing important information that may impact the approach to therapy,” the agency added.
The FDA also noted that no serious adverse reactions were attributed to Ga 68 PSMA-11. The most common adverse reactions were nausea, diarrhea, and dizziness.
The FDA said there is a risk for misdiagnosis because Ga 68 PSMA-11 binding may occur in other types of cancer, and certain nonmalignant processes may lead to errors in interpreting images. In addition, there are radiation risks because Ga 68 PSMA-11 contributes to a patient’s overall long-term cumulative radiation exposure, which is associated with an increased risk for cancer.
