The Food and Drug Administration has approved trofinetide oral solution (Daybue, Acadia Pharmaceuticals) as the first treatment of Rett syndrome in adults and children aged 2 years and older.

Rett syndrome is a rare, genetic neurodevelopmental disorder that affects about 6,000-9,000 people in the United States, mostly females.

Symptoms typically present between 6 and 18 months of age, with patients experiencing a rapid decline with loss of fine motor and communication skills.

Trofinetide is a synthetic analogue of the amino-terminal tripeptide of insulinlike growth factor-1 (IGF-1), which occurs naturally in the brain. The drug is designed to treat the core symptoms of Rett syndrome by potentially reducing neuroinflammation and supporting synaptic function.

The approval of trofinetide was supported by results from the pivotal phase 3 LAVENDER study that tested the efficacy and safety of trofinetide vs. placebo in 187 female patients with Rett syndrome, aged 5-20 years. 

A total of 93 participants were randomly assigned to twice-daily oral trofinetide, and 94 received placebo for 12 weeks.

After 12 weeks, trofinetide showed a statistically significant improvement from baseline, compared with placebo, on both the caregiver-assessed Rett Syndrome Behavior Questionnaire (RSBQ) and 7-point Clinical Global Impression-Improvement (CGI-I) scale. 

The drug also outperformed placebo at 12 weeks in a key secondary endpoint: the composite score on the Communication and Symbolic Behavior Scales Developmental Profile Infant-Toddler Checklist-Social (CSBS-DP-IT Social), a scale on which caregivers assess nonverbal communication.

The most common adverse events with trofinetide treatment were diarrhea and vomiting. Almost all these events were considered mild or moderate.

‘Historic day’

“This is a historic day for the Rett syndrome community and a meaningful moment for the patients and caregivers who have eagerly awaited the arrival of an approved treatment for this condition,” Melissa Kennedy, MHA, chief executive officer of the International Rett Syndrome Foundation, said in a news release issued by Acadia.

“Rett syndrome is a complicated, devastating disease that affects not only the individual patient, but whole families. With today’s FDA decision, those impacted by Rett have a promising new treatment option that has demonstrated benefit across a variety of Rett symptoms, including those that impact the daily lives of those living with Rett and their loved ones,” Ms. Kennedy said.

Trofinetide is expected to be available in the United States by the end of April.

The Food and Drug Administration has issued a warning about the potential for patients to experience anaphylactic reactions after a negative skin test with any allergenic extract used to diagnose food allergies.

The FDA is requiring that an anaphylaxis warning after false-negative food allergen skin test results be added to the labels of these products in light of reports to the FDA’s Adverse Event Reporting System (FAERS), according to a March 3 statement.

The action follows the recognition of an increase in adverse event reports of false-negative test results with specific lots of “ALK-Abello’s Allergenic Extract-Peanut (Arachis hypogaea) – For Diagnostic Use Only.” Some of these reports “were associated with life-threatening anaphylaxis from subsequent exposure to peanut,” according to the statement. “FDA determined that the risk of anaphylaxis following false-negative food allergen skin test results is applicable to all allergenic extracts for the diagnosis of food allergies,” the statement notes.

To date, four lots of allergenic extracts have been voluntarily withdrawn from the market by the manufacturer, in November and December 2022, and should not be used.

Although some allergenic extracts are standardized, those used in the diagnosis of food allergy currently licensed by the FDA for use in the United States are nonstandardized, so potency may vary by lot.

The FDA advises health care professionals to consider confirming a negative skin test with serologic testing for peanut-specific IgE or conducting a medically supervised oral food challenge in patients, “based on the patient’s clinical history and the index of suspicion.”

The FDA also urges patients to discuss negative food allergen skin test results with their health care providers to determine the possible need for additional testing and to review the symptoms of a severe allergic reaction.

Any adverse events or side effects associated with allergenic products should be reported to the FDA via the FDA’s MedWatch Safety Information and Adverse Event Reporting Program.

Several years after xylazine first began appearing as an additive in illicit street drugs – and as its use spreads nationwide – the Food and Drug Administration says it will more closely monitor imports.

The agency issued an import alert, which gives it the power to detain raw ingredients or bulk finished product if the shipments are suspected to be in violation of the law. Xylazine was first approved by the FDA in 1972 as a sedative and analgesic for use only in animals.

It is increasingly being detected and is usually mixed with fentanyl, cocaine, methamphetamine, and other illicit drugs. A January 2023 study by Nashville-based testing company Aegis Sciences found xylazine in 413 of about 60,000 urine samples and in 25 of 39 states that submitted tests. The vast majority of xylazine-positive samples also tested positive for fentanyl.

The FDA said it would continue to ensure the availability of xylazine for veterinary use, and the American Veterinary Medicine Association said in a statement that it “supports such efforts to combat illicit drug use.”

FDA Commissioner Robert M. Califf, MD, said in a statement that the agency “remains concerned about the increasing prevalence of xylazine mixed with illicit drugs, and this action is one part of broader efforts the agency is undertaking to address this issue.”

The Food and Drug Administration has made changes to existing mammography regulations.

A final rule, updating the regulations issued under the Mammography Quality Standards Act of 1992, requires that mammography facilities notify patients about the density of their breasts, strengthens the FDA’s oversight of facilities, and provides guidance to help physicians better categorize and assess mammograms, according to a March 9 press release.

The rule requires implementation of the changes within 18 months.

According to the final rule document, the updates are “intended to improve the delivery of mammography services” in ways that reflect changes in mammography technology, quality standards, and the way results are categorized, reported, and communicated to patients and providers.

For instance, mammography reports must include an assessment of breast density to provide greater detail on the potential limitations of the mammogram results and allow patients and physicians to make more informed decisions, such as the possibility of additional imaging for women with dense breast tissue.

“Today’s action represents the agency’s broader commitment to support innovation to prevent, detect and treat cancer,” said Hilary Marston, MD, MPH, FDA’s chief medical officer, in the agency’s press release. The FDA remains “committed to advancing efforts to improve the health of women and strengthen the fight against breast cancer.”

Two diabetes management devices that aid in the precision of insulin delivery have been recently cleared by the Food and Drug Administration.

On March 2, the FDA cleared the Android version of Bigfoot Biomedical’s Unity Mobile App for use with its system of smart pen caps that are compatible with different disposable insulin pens for administering both long-acting and rapid-acting insulin.

The system, which has been compatible with iOS devices since May 2021, is “the first and only FDA-cleared smart injection system that turns CGM [continuous glucose monitoring] data into dosing recommendations displayed right on the pen cap for people using multiple daily [insulin] injection therapy,” according to a company statement.

The Bigfoot app allows users to input and review provider treatment recommendations, displays current glucose ranges, and delivers real-time alerts.

Once it is commercially launched, the Android phone application will be available via the Google Play Store. “Given that 41% of U.S. smartphone users choose Android devices, this clearance enables expanded access to a large group of people with diabetes,” the company said.

On March 6, the FDA cleared the Abbott FreeStyle Libre 2 and FreeStyle Libre 3 devices as “integrated” CGM sensors. This means that they can now be used as components in automated insulin delivery systems, along with insulin pumps and connectivity software.

Abbott is working with insulin pump manufacturers Insulet and Tandem in the United States for integration with the FreeStyle Libre versions 2 and 3. Outside the United States, the Libre 3 is already authorized to work with mylife Loop from Ypsomed and CamDiab in Germany. Further launches are expected in the United Kingdom, Switzerland, and the Netherlands later this year.

The modified FreeStyle Libre 2 and FreeStyle Libre 3 sensors have been cleared for use by patients as young as age 2 years and for up to 15 days, in contrast to the previous versions, which were available for patients as young as 4 years for use up to 14 days. The FDA has cleared all Libre sensors – 2 and 3, current and future versions – for use by pregnant women with any type of diabetes.

The modified sensors will be available in the United States later this year and will eventually replace the Libre sensors in current use, the company said in a statement.

“The FreeStyle Libre portfolio is still the most affordable CGM on the market,” an Abbott representative said in an interview.

The Centers for Disease Control and Prevention has issued a Health Alert Network (HAN) health advisory notifying clinicians and public health officials of a confirmed measles case in an individual who for 2 days (February 17-18) attended a large religious gathering that was attended by an estimated 20,000 people at Asbury University in Wilmore, Ky.

Given that large numbers of people might have been exposed to the attendee (who was not vaccinated) and that the individual had a history of recent international travel, the CDC has encouraged clinicians to be vigilant for patients presenting with symptoms that meet the measles case definition. A steady increase in measles cases from 49 in 2021 to 121 in 2022 in children who were not fully vaccinated – coupled with outbreaks in Ohio and Minnesota – underscores the potential gravity of the CDC advisory as well as the need to mitigate the risk of ongoing or secondary transmission.

Currently, little is known about the individual who contracted measles other than the fact that he is a resident of Jessamine County, Ky., according to a news release issued by the Kentucky Department of Public Health. It is the third confirmed case in Kentucky over the past 3 months. State and national health officials are concerned that the individual might have transmitted measles to attendees visiting from other states.

David Sugerman, MD, MPH, a medical officer in CDC’s division of viral diseases and lead for the measles, rubella, and cytomegalovirus team, noted that the timing of the alert coincides with the period in which persons who had had contact with the initial case patient might be expected to develop symptoms.

For clinicians, “It’s really about considering measles in any un- or undervaccinated patient that arrives at a clinic and recently traveled internationally,” Dr. Sugerman told this news organization. He explained that “when doctors are seeing patients, they’re not going to necessarily share that information off the bat when they present with fever or rash, or if their child has fever and rash, or that they traveled internationally. So, eliciting that history from the patient or their parents is really critical.”

The CDC recommends that measles be considered in anyone presenting with a febrile illness and symptoms that are clinically compatible with measles (that is, rash, cough, coryza, or conjunctivitis), as well as in patients who have recently traveled abroad, especially to countries with ongoing outbreaks, including India, Somalia, and Yemen.

“In general, if they’ve traveled internationally and they are undervaccinated, measles should be part of the differential diagnosis,” Sugerman said. He also emphasized the need to follow airborne isolation precautions in addition to general infection control measures.

Immediate triage is critical, especially since overcrowded waiting rooms might be filled with patients who are not yet eligible for vaccination or are not up to date or fully vaccinated.

“Measles is under airborne isolation criteria and precautions, and therefore, [patients] need to be placed as soon as possible into a negative pressure or airborne infection isolation room – and that should be a single room,” he explained. He noted, “In some settings, there may not be a negative pressure room, e.g., an outpatient pediatrics or family medicine office.”

Dr. Sugerman said that in these circumstances, patients should be placed in a room with masked health care providers who have received two doses of measles, mumps, and rubella (MMR) vaccine and that they should wear an N95 mask when entering the room and interviewing the patient.

Clinicians should follow CDC’s testing recommendations and collect a nasopharyngeal or throat swab or a urine specimen for PCR testing and a blood specimen for serology. In addition, they should immediately report cases to local and state public health authorities.

For all patients, it’s critical to be up to date on MMR vaccines, especially persons who are going to be traveling internationally. “We recommend that when they’ve got infants traveling with them who are 6-11 months of age, that they get a first dose (which we consider a zero dose), because they need a routine dose at 12-15 months, and then 4-6 years,” said Dr. Sugerman. He said that it’s safe for adults who are unsure of their status to receive an MMR dose as well.

Dr. Sugerman stressed that despite major strides, “we just don’t have enough coverage in all individuals in this country. Because people are traveling as often as they are, it can be imported. Until measles is eliminated globally, there’s going to be an ongoing risk of importation and potential spread amongst others in their household or community, especially amongst individuals who are not fully vaccinated and, in particular, amongst those who are unvaccinated,” he said.

Dr. Sugerman reports no relevant financial relationships.

“Measles is under airborne isolation criteria and precautions, and therefore, [patients] need to be placed as soon as possible into a negative pressure or airborne infection isolation room – and that should be a single room,” he explained. He noted, “In some settings, there may not be a negative pressure room, e.g., an outpatient pediatrics or family medicine office.”

Dr. Sugerman said that in these circumstances, patients should be placed in a room with masked health care providers who have received two doses of measles, mumps, and rubella (MMR) vaccine and that they should wear an N95 mask when entering the room and interviewing the patient.

Clinicians should follow CDC’s testing recommendations and collect a nasopharyngeal or throat swab or a urine specimen for PCR testing and a blood specimen for serology. In addition, they should immediately report cases to local and state public health authorities.

For all patients, it’s critical to be up to date on MMR vaccines, especially persons who are going to be traveling internationally. “We recommend that when they’ve got infants traveling with them who are 6-11 months of age, that they get a first dose (which we consider a zero dose), because they need a routine dose at 12-15 months, and then 4-6 years,” said Dr. Sugerman. He said that it’s safe for adults who are unsure of their status to receive an MMR dose as well.

Dr. Sugerman stressed that despite major strides, “we just don’t have enough coverage in all individuals in this country. Because people are traveling as often as they are, it can be imported. Until measles is eliminated globally, there’s going to be an ongoing risk of importation and potential spread amongst others in their household or community, especially amongst individuals who are not fully vaccinated and, in particular, amongst those who are unvaccinated,” he said.

Dr. Sugerman reports no relevant financial relationships.

The Centers for Disease Control and Prevention has issued a Health Alert Network (HAN) health advisory notifying clinicians and public health officials of a confirmed measles case in an individual who for 2 days (February 17-18) attended a large religious gathering that was attended by an estimated 20,000 people at Asbury University in Wilmore, Ky.

Given that large numbers of people might have been exposed to the attendee (who was not vaccinated) and that the individual had a history of recent international travel, the CDC has encouraged clinicians to be vigilant for patients presenting with symptoms that meet the measles case definition. A steady increase in measles cases from 49 in 2021 to 121 in 2022 in children who were not fully vaccinated – coupled with outbreaks in Ohio and Minnesota – underscores the potential gravity of the CDC advisory as well as the need to mitigate the risk of ongoing or secondary transmission.

Currently, little is known about the individual who contracted measles other than the fact that he is a resident of Jessamine County, Ky., according to a news release issued by the Kentucky Department of Public Health. It is the third confirmed case in Kentucky over the past 3 months. State and national health officials are concerned that the individual might have transmitted measles to attendees visiting from other states.

David Sugerman, MD, MPH, a medical officer in CDC’s division of viral diseases and lead for the measles, rubella, and cytomegalovirus team, noted that the timing of the alert coincides with the period in which persons who had had contact with the initial case patient might be expected to develop symptoms.

For clinicians, “It’s really about considering measles in any un- or undervaccinated patient that arrives at a clinic and recently traveled internationally,” Dr. Sugerman told this news organization. He explained that “when doctors are seeing patients, they’re not going to necessarily share that information off the bat when they present with fever or rash, or if their child has fever and rash, or that they traveled internationally. So, eliciting that history from the patient or their parents is really critical.”

The CDC recommends that measles be considered in anyone presenting with a febrile illness and symptoms that are clinically compatible with measles (that is, rash, cough, coryza, or conjunctivitis), as well as in patients who have recently traveled abroad, especially to countries with ongoing outbreaks, including India, Somalia, and Yemen.

“In general, if they’ve traveled internationally and they are undervaccinated, measles should be part of the differential diagnosis,” Sugerman said. He also emphasized the need to follow airborne isolation precautions in addition to general infection control measures.

Immediate triage is critical, especially since overcrowded waiting rooms might be filled with patients who are not yet eligible for vaccination or are not up to date or fully vaccinated.

“Measles is under airborne isolation criteria and precautions, and therefore, [patients] need to be placed as soon as possible into a negative pressure or airborne infection isolation room – and that should be a single room,” he explained.

The Food and Drug Administration has expanded the indication for adjuvant abemaciclib (Verzenio) in combination with endocrine therapy for patients with hormone receptor–positive, HER2-negative, node-positive early breast cancer who are at high risk for recurrence.

Abemaciclib was previously approved for this group of high-risk patients with the requirement that they have a Ki-67 score of at least 20%. The new expansion removes the Ki-67 testing requirement, meaning more patients are now eligible to receive this drug. High-risk patients eligible for the CDK4/6 inhibitor can now be identified solely on the basis of nodal status, tumor size, and tumor grade.

The FDA’s decision to expand the approval was based on 4-year data from the phase 3 monarchE trial of adjuvant abemaciclib, which showed benefit in invasive disease-free survival beyond the 2-year treatment course.

At 4 years, 85.5% of patients remained recurrence free with abemaciclib plus endocrine therapy, compared with 78.6% who received endocrine therapy alone, an absolute difference in invasive disease-free survival of 6.9%.

“The initial Verzenio FDA approval in early breast cancer was practice changing and now, through this indication expansion, we have the potential to reduce the risk of breast cancer recurrence for many more patients, relying solely on commonly utilized clinicopathologic features to identify them,” Erika P. Hamilton, MD, an investigator on the monarchE clinical trial, said in a press release.

The Food and Drug Administration has declined to approve omecamtiv mecarbil (Cytokinetics) for treatment of adults with chronic heart failure with reduced ejection fraction (HFrEF), citing a lack of evidence on efficacy.

Waldemarus/iStock/Getty Images Plus

Omecamtiv mecarbil is a first-in-class, selective cardiac myosin activator designed to improve cardiac performance.

Last December, a panel of FDA advisers recommended against approval of omecamtiv mecarbil for chronic HFrEF, as reported by this news organization.

The FDA Cardiovascular and Renal Drugs Advisory Committee voted 8 to 3 (with no abstentions) that the benefits of omecamtiv mecarbil do not outweigh the risks for HFrEF. The drug had a PDUFA date of February 28.

The committee’s decision was based on results from the phase 3 GALACTIC-HF trial, which enrolled 8,256 patients with HFrEF who were at risk of hospitalization and death, despite standard-of-care therapy.

As previously reported by this news organization, omecamtiv mecarbil produced a positive result for the study’s primary endpoint, with a 2.1% absolute reduction in the combined rate of cardiovascular (CV) death, first HF hospitalization, or first urgent visit for HF, compared with placebo during a median follow-up of about 22 months.

This represented an 8% relative risk reduction and broke down as a 0.6% absolute drop in CV death, compared with placebo, a 0.7% cut in HF hospitalization, and a 0.8% drop in urgent outpatient HF visits.

In a complete response letter, the FDA said GALACTIC-HF is “not sufficiently persuasive to establish substantial evidence of effectiveness for reducing the risk of heart failure events and cardiovascular death” in adults with HFrEF, Cytokinetics shared in a news release.

Further, the FDA said results from an additional clinical trial of omecamtiv mecarbil are required to establish substantial evidence of effectiveness for the treatment of HFrEF, with benefits that outweigh the risks, Cytokinetics said.

The company said it will request a meeting with the FDA to gain a better understanding of what may be required to support potential approval of omecamtiv mecarbil. However, the company also said it has “no plans” to conduct an additional clinical trial of omecamtiv mecarbil.

Instead, the company said its focus remains on the development of aficamten, the next-in-class cardiac myosin inhibitor, currently the subject of SEQUOIA-HCM, a phase 3 clinical trial in patients with obstructive hypertrophic cardiomyopathy.

There is a potential risk of early structural valve deterioration with the Abbott Trifecta valve and Trifecta valve with glide technology (Trifecta GT), the U.S. Food and Drug Administration says in a letter to health care professionals posted on its website.  

Evidence in the literature suggests a higher cumulative incidence of early structural valve deterioration (SVD) and a lower freedom from reintervention due to SVD with the Trifecta valves, compared with other commercially available bovine pericardial valves, the FDA says.

The Trifecta and Trifecta GT valves are heart valve replacement devices intended to treat diseased, damaged, or malfunctioning native or prosthetic aortic heart valves, the letter notes. The first-generation Trifecta valve was approved in 2011 but is no longer marketed in the United States. The Trifecta GT valve was approved in 2016.

Medical device reports (MDRs) received by the FDA describe early SVD with Trifecta valves, with a peak time to SVD of 3 to 4 years post-implant. “Reported outcomes include surgical valve explant/replacement, transcatheter valve-in-valve intervention, and in some cases death,” the FDA notes.

In a letter to customers, Abbott says a “complaint analysis has shown that most cases of early SVD which occur within 5 years post-implant are characterized as a non-calcific leaflet tear, while most cases of late SVD which occur beyond 5 years post-implant are characterized as a fibrous-calcific SVD.” 

The FDA recommends that health care providers take the following actions:

• Be aware of the potential risk of early SVD with Trifecta valves, and current patient management considerations, as communicated by Abbott.
• Discuss the risks and benefits of all available aortic valve treatment options with patients and caregivers as part of shared clinical decision-making prior to surgery.
• Read and carefully follow the Instructions for Use when implanting a Trifecta GT valve.
• Monitor patients who have undergone implantation with Trifecta valves for signs and symptoms of potential SVD.
• Instruct patients to seek medical attention with new onset of symptoms such as shortness of breath or fatigue.
• Ensure lifelong follow-up visits, conducted at least yearly, including transthoracic echocardiogram assessment of the valve beginning 1-year post-implant.

The FDA is working with Abbott to further evaluate the issue and develop additional patient management strategies, if needed. The FDA says it will continue to monitor the literature and reports of adverse events related to the issue.

Clinicians are encouraged to report any adverse events or quality problems with the Trifecta valves to their local Abbott representative or the customer service department at 1-800-544-1664.

Health care professionals can also report adverse reactions or quality problems they experience using these devices to the FDA’s MedWatch program.

The European Commission has granted conditional marketing authorization for etranacogene dezaparvovec (Hemgenix), the first and only one-time gene therapy for the treatment of severe and moderately severe hemophilia B (congenital factor IX deficiency) in adults without a history of factor IX inhibitors.

The approval means that the product will now be available in all the countries of the European Union as well as the European Economic Area.

The gene therapy was approved in the United States in November 2022. It was launched with a price tag of $3.5 million, making it the most expensive treatment to date.

The treatment comprises a one-time infusion of a functional gene that acts as a blueprint for coagulation factor IX, a protein important for blood clotting, stated the manufacturer, CSL.

People living with hemophilia B currently require lifelong treatment of intravenous infusions of factor IX to maintain sufficient levels, which can have a significant impact on their quality of life and well-being, the company explained in its press release.

The approval was based on findings from the pivotal HOPE-B trial, a single-arm, open-label study of 54 men who relied on factor IX replacement therapy; first results from this trial were reported at the 2020 annual meeting of the American Society of Hematology.

The results showed that patients with hemophilia B treated with the gene therapy demonstrated stable and durable increases in mean factor IX activity (with a mean factor IX activity of 36.9%), which led to an adjusted annualized bleeding rate reduction of 64%.

After receiving the gene therapy, 96% of patients discontinued routine factor IX prophylaxis and mean factor IX consumption was reduced by 97% at 18 months post treatment compared with the lead-in period, the company noted.

“Data from the HOPE-B study demonstrate the potential of Hemgenix to remove the need for routine prophylaxis by providing durable factor IX activity, as well as improved bleeding outcomes and quality of life for people with hemophilia B,” said one of the trialists, Wolfgang Miesbach, MD, PHD, head of coagulation disorders at the Comprehensive Care Center, University Hospital of Frankfurt, Germany.

This European approval “marks an important step forward in the treatment of hemophilia B, which could be transformative for people who are debilitated by bleeds into their muscles, joints, and internal organs, alleviating the burden of lifelong intravenous infusions of factor IX products,” Dr. Miesbach said in the company press release.
