Mavacamten Demonstrates Sustained Symptom Improvement in Patients with Obstructive Hypertrophic Cardiomyopathy

Table of Contents

Manchester – New data presented at the British Cardiovascular Society Annual Conference 2025 reaffirms the effectiveness of mavacamten (Camzyos, Bristol Myers Squibb) in treating symptomatic obstructive hypertrophic cardiomyopathy (oHCM). The cardiac myosin inhibitor has shown promising results in real-world settings, mirroring the outcomes seen in clinical trials such as EXPLORER-HCM and VALOR-HCM.

Significant Symptom Relief with Mavacamten

A study across three U.K. centers revealed that mavacamten treatment led to symptomatic improvement in approximately 70% to 80% of patients. Furthermore, 90% of patients experienced a notable reduction-30 mm Hg or more-in the left ventricular outflow tract (LVOT) gradient, a key indicator of reduced obstruction.

Mavacamten,a first-in-class therapy,addresses oHCM by normalizing heart muscle contractility,decreasing LVOT obstruction,and enhancing cardiac filling pressures. Hypertrophic Cardiomyopathy frequently enough develops over decades, with symptoms potentially emerging long before more severe complications arise.

Did You Know? Hypertrophic Cardiomyopathy (HCM) affects roughly 1 in 500 people in both the U.K. and the U.S., with obstructive HCM accounting for about two-thirds of these cases.

Patient Perspectives on Mavacamten

Katharine Mcintosh, Head Of Research and Policy At Cardiomyopathy U.K., highlighted the excitement surrounding mavacamten among patients, calling it the “first big cardiomyopathy-specific drug.” Despite its recommendation for use by the National Health Service in England, wales (2023) and Scotland (2024), Mcintosh expressed concerns about the pace of its implementation.

A Cardiomyopathy U.K. survey indicated that patients who have received mavacamten report highly positive experiences, with many describing the treatment as “life changing.”

Challenges to overcome

Several factors impede the widespread use of mavacamten. The drug’s prescription and monitoring necessitate specialists experienced in cardiomyopathy treatment, which are not universally accessible. Guidelines require echocardiography before and during treatment, as well as genetic testing for CYP2C19 to determine appropriate dosing.

The European Society of Cardiology (ESC) recently updated its guidelines to include mavacamten as a Class I recommendation for symptomatic adults with oHCM despite optimal medical therapy, reflecting its growing recognition in treatment protocols (ESC Guidelines, August 2024).

Considerations Before Prescribing Mavacamten:

  • Close monitoring is crucial due to the risk of left ventricular systolic dysfunction.
  • Potential CYP2C19-related drug interactions necessitate pharmacy involvement.
  • Thorough counseling is vital due to the risk of fetal toxicity.

Long-term follow-up can be reduced to every 3-6 months after the initial 12-week period. While currently indicated for symptomatic, severe LVOT obstruction, there is potential for broader application in the future.

Pro Tip: Regular echocardiographic monitoring following mavacamten initiation, while initially intensive, can be reduced over time as clinicians gain more experience with the drug.

Mavacamten: Key Considerations

What are the potential risks associated with different prenatal genetic testing methods, and how can I mitigate those risks?

Preventing Genetic Disease Before Birth: Strategies and Options

The prospect of bringing a baby into the world is incredibly exciting, but it can also bring concerns about their health. Preventing genetic diseases before birth is becoming increasingly possible thanks to advances in medical technology. This guide explores various methods used to assess and mitigate the risks associated with genetic conditions, empowering you to make informed decisions for a healthy pregnancy journey. Understanding inherited genetic disorders and the associated prenatal genetic testing procedures is crucial.

Understanding Genetic disease Risks: Key Considerations

Before discussing preventative measures, it’s important to grasp the fundamentals of genetic disorders. These conditions arise from changes, or mutations, in an individual’s genes. These gene mutations can be inherited from parents or occur spontaneously. Several factors can increase the risk of a child inheriting a genetic disorder, including:

  • Family History: A family history of genetic diseases considerably raises the risk.
  • Maternal Age: The risk of certain genetic conditions,like Down syndrome,increases with maternal age.
  • Ethnicity: Certain ethnic groups have a higher prevalence of specific genetic conditions (e.g., Tay-Sachs disease in individuals of Ashkenazi Jewish descent).
  • Consanguinity: Having parents who are closely related increases the chances of inheriting recessive genes for genetic diseases.

Types of Genetic Diseases

Genetic diseases span a wide spectrum, varying in severity and impact. Broadly, they fall into a few primary categories:

  • Single-gene disorders: Caused by a single gene mutation (e.g., cystic fibrosis, sickle cell anemia).
  • Chromosome disorders: Result from abnormalities in the number or structure of chromosomes (e.g., Down syndrome, Turner syndrome).
  • Multi-factorial disorders: Result from a combination of genetic and environmental factors (e.g., heart disease).

Prenatal Screening and Diagnostic Techniques

Understanding the available prenatal screening options is essential for proactive prenatal care. These techniques offer varying levels of information and risk assessment.

Carrier Screening

Even before conceiving, prospective parents can undergo carrier screening to determine if they carry genes for specific genetic disorders. This involves testing for the presence of a mutated gene, which, if present in both parents, could result in a child with the disease. The following table provides examples of common genetic disorders screened for.

Disorder Description Most Common Ethnic Groups Affected
Cystic Fibrosis (CF) A progressive, genetic disease that causes the body to produce thick, sticky mucus that can clog the lungs and obstruct the pancreas. Caucasians (European descent)
Spinal Muscular Atrophy (SMA) A genetic disease affecting the part of the nervous system that controls voluntary muscle movement. All ethnicities
Tay-Sachs Disease A rare genetic disorder that progressively destroys nerve cells in the brain and spinal cord. Ashkenazi Jewish, French Canadian, and Cajun populations

Non-Invasive Prenatal Testing (NIPT)

Non-invasive prenatal testing (NIPT) is a highly advanced screening method offering a risk assessment of the developing baby for chromosomal abnormalities, such as Down Syndrome and other chromosome disorders. It involves a simple blood test taken from the mother, analyzing cell-free fetal DNA (cffDNA) in the maternal blood. Early detection via fetal DNA testing allows for more informed decisions at the beginning of the pregnancy.

Diagnostic Testing

If initial screening results suggest a higher-than-average risk,or if a family history warrants it,diagnostic tests are offered to confirm or rule out a diagnosis.These tests provide definitive answers, but they carry a small risk of miscarriage. Prenatal diagnosis is a vital part of a complete family history.

Common diagnostic tests include:

  • Chorionic Villus Sampling (CVS): Performed between 10 and 13 weeks of pregnancy, involving the removal of a small sample of cells from the placenta.
  • amniocentesis: Usually performed between 15 and 20 weeks of pregnancy, involving the extraction of a sample of amniotic fluid.

Making Informed Decisions and Seeking support

The information obtained from screening and diagnostic tests is crucial.Receiving abnormal test results can be incredibly emotional, and it is vital you feel supported throughout any decision-making process. You can consider:

  • Genetic Counseling: Genetic counselors provide valuable information, explain test results in detail, and discuss the implications of specific genetic conditions. They can also help guide you through tough decisions.
  • support Groups: Connecting with other families facing similar challenges can offer comfort, shared experiences, and emotional support.
  • Further Medical Consultation: Consult with medical specialists (e.g., perinatologists, pediatricians) to discuss the specifics of the diagnosis, management options, and long-term outcomes.

The decision-making process is deeply personal. Your healthcare provider can guide you through the process. They can assist with further genetic counseling,and offer support to assist with decisions regarding your baby,and support and resources for every step.

Scientist Defends STRmix DNA Software in Caneiro Family Murder Hearing

by Alexandra Hartman Editor-in-Chief
written by Alexandra Hartman Editor-in-Chief

4 minute read

Scientist defends DNA software in Caneiro murder trial

John Buckleton, a prominent scientist with the Institute of Environmental Science and Research in New Zealand, countered skepticism surrounding STRmix software, stating that it has never produced a false inclusion in cases.

FREEHOLD – The co-creator of the contentious STRmix software, which analyzed DNA evidence linking Paul Caneiro to the brutal murder of four family members, staunchly defended the program during a two-day court hearing, addressing a barrage of inquiries regarding potential limitations and errors.

Buckleton, who serves as the principal scientist at the institute, took the witness stand on Nov. 14 and 15, affirming the reliability of STRmix as the court deliberates the admissibility of the DNA evidence it generated in advance of Caneiro’s impending trial.

Caneiro, aged 57 and hailing from Ocean Township, faces serious charges for the murders of his brother Keith, 50; sister-in-law Jennifer, 45; and his young niece Sophia, aged 8, along with his nephew Jesse, aged 11. The bodies of the victims were discovered on the scene of a horrific crime at Keith Caneiro’s Colts Neck mansion on Nov. 21, 2018.

After the murders, DNA identified as a mixture of Paul and Sophia Caneiro was uncovered on gloves and jeans found in the basement of Paul Caneiro’s Ocean Township residence.

During questioning on the second day of the hearing, Monmouth County prosecutor’s deputy Christopher Decker asked Buckleton, “Are you satisfied in the fact that STRmix is generally accepted in the scientific community?” Buckleton confidently answered, “Yes.”

When pressed further by Decker on whether there was any doubt regarding STRmix’s suitability for application in cases, Buckleton reiterated with an emphatic, “No.”

The outcomes stemming from this hearing hold significant ramifications statewide for the use of STRmix, as the software recently gained traction within New Jersey State Police laboratories. However, it faces its first major legal scrutiny in New Jersey courts.

Unlike conventional DNA analysis, which typically relies on random match probability to calculate the chances of finding a match within the general population, STRmix employs a cutting-edge approach known as probabilistic genotyping. This approach is tailored for processing small DNA quantities and complex mixtures that traditional testing methods often fail to analyze effectively.

On the second day of testimony, Decker challenged Buckleton regarding allegations of “miscodes” present within STRmix, which have surfaced in defense critiques. Buckleton acknowledged that there were indeed 15 coding errors, all of which have since been rectified and publicly addressed on STRmix’s official website. He asserted that these errors had minimal effects on criminal case outcomes.

Decker highlighted a finding from one defense expert, which claimed that these errors influenced 60 criminal proceedings, necessitating recalibrations of the “likelihood ratio” in about 24 of those cases. Buckleton replied, “It caused a relatively minor difference in the population reference counting,” countering the notion that the errors caused significant harm.

Buckleton dismissed claims from the defense expert suggesting that the software’s errors impacted thousands of criminal convictions. “It did not affect thousands of convictions,” Buckleton stated unequivocally, clarifying that in the 60 cases examined, adjustments were made, but many yielded identical results post-correction. He insisted that all identified issues were resolved before any trials commenced.

Christopher Godin from the Public Defender’s Office pressed Buckleton about the implications of these errors, observing that many criminal cases—particularly those resulting in guilty pleas—might not reveal potential miscodes affecting DNA evidence. “In those cases, it’s not necessarily likely a person would discover that a miscode affected DNA evidence in that case,” Godin argued.

In response, Buckleton retained his stance, stating, “Miscodes have not affected DNA evidence. The miscodes that we have detected to date all have a minor effect on the numerical values or on a peripheral functionality.”

Godin further queried Buckleton on the software’s limitations regarding familial DNA analysis, pointing out that relatives share alleles, which can complicate the interpretation of DNA evidence. Buckleton conceded, “Yes,” confirming that family members can sometimes deposit DNA that might falsely suggest belonging to another relative.

Godin posited a serious concern that the DNA analysis conducted in the Caneiro case may have incorrectly excluded Keith Caneiro from the relevant DNA profiles, adversely impacting Paul Caneiro’s defense. “There are exclusions that STRmix has made that are very harmful to Mr. (Paul) Caneiro,” Godin noted, to which Buckleton affirmatively replied, “Absolutely.”

Authorities assert that Paul Caneiro allegedly committed these gruesome murders after his brother Keith uncovered his embezzlement from their shared business ventures. The bodies of the victims were tragically discovered by first responders at the scene of a fire that was igniting at the Colts Neck mansion. Reports indicate that Keith Caneiro had been shot four times in the head and once in the back, while Jennifer and the two children suffered multiple stab wounds and were severely burned, with Jennifer also shot in the head.

It is alleged that following the murders, Paul Caneiro set fire to the family mansion in an attempt to conceal the crime and then ignited his own residence to mislead investigators into believing a dangerous criminal was targeting the entire family.

Caneiro is slated to face trial in this highly publicized case in the early part of next year.

The hearing on the DNA evidence is anticipated to resume on Monday, Nov. 18.
