AMRA Medical’s Whole-body MRI Analysis Used in FSHD Clinical Trial Research Network Study for Biomarker Development

AMRA Medical, a digital health company delivering a new standard in body composition analysis through rapid whole-body magnetic resonance imaging (MRI), today announced its involvement with the Facioscapulohumeral Muscular Dystrophy (FSHD) Clinical Trial Research Network (CTRN) to support the Motor Outcomes to Validate Evaluations Plus (MOVE+) Study—a natural history study for people living with FSHD.

MOVE+ is a sub-study of the ongoing natural history study called Motor Outcomes to Validate Evaluations in FSHD (MOVE FSHD) and adds MRI—made possible in part through sponsorship by Avidity Biosciences, FSHD Society, Friends of FSH Research, and FSHD Canada. MOVE+ will enroll 200 participants across 12 sites in the US and two planned sites in Canada with the goal of better understanding how to utilize whole-body MRI to discover and validate specific biomarkers for FSHD that can inform future clinical trials. The results of this study will be particularly important for MOVE+ sponsoring companies like Avidity Biosciences—a biopharmaceutical company developing a new class of RNA therapeutics with an advancing and expanding pipeline that includes multiple skeletal muscle programs.

“The FSHD CTRN is very excited about our collaboration with AMRA. We think that the use of whole-body MRI will be important not only for trial planning, but to better understand and treat people with FSHD,” says Jeffrey Statland, MD, Professor of Neurology at the University of Kansas Medical Center, which also is the Clinical Coordinating Center for the FSHD CTRN.

To date, the MOVE study has used functional tests as primary outcomes, but recent studies have shown the promise of MRI for FSHD. To complement functional tests, MOVE+ will use AMRA’s whole-body, whole-muscle MRI protocol and analysis, which involves measuring 36 muscles throughout the participant’s shoulders, arms, torso and legs—distal to proximal and bilaterally. Specifically, the researchers will quantify muscle fat infiltration, lean muscle volume, and muscle fat fraction at twotime points throughout a three-year study period for each individual.

Evaluating entire muscles throughout the whole body provides a fuller picture of how the disease presents and progresses, which is critical to understand when searching for the most optimal outcome measurements to use in FSHD clinical trials. Not only is this applicable for FSHD, but also other neuromuscular disorders including DMD, LGMD, Myotonic Dystrophy, Mitochondrial Myopathy, SBMA, SIBM, and Pompe Disease.

Data from clinical studies of STK-001 demonstrated clinical benefit for patients ages 2 to 18 years old, including reductions in seizures and improvements in cognition and behavior that support the potential for disease modificatio. Analysis of 72 patients treated in STK-001 clinical trials suggests that higher STK-001 drug exposure in brain leads to greater seizure reductions. Two-year data from the longest prospective natural history study of Dravet syndrome showed that, on average, patients experienced no meaningful improvement in convulsive seizure frequency and exhibited widening gaps in cognition and behavior despite treatment with the best available anti-seizure medicines.
"Exact Sciences is looking forward to presenting new evidence at SABCS that adds important perspectives to treating breast cancer patients and showing that some patients may be able to de-escalate treatments and still have positive outcomes," said Dr. Rick Baehner, Chief Medical Officer, Precision Oncology, Exact Sciences. "Every year, we build upon the precedent set by the Oncotype DX Breast Recurrence Score® test and its prognostic and predictive abilities to determine the chemotherapy benefit for specific breast cancer patients. We are pleased to see authorities expanding access to this test as we continue to develop key evidence in collaboration with some of the world's most prestigious, breast cancer-focused organizations."
Clozapine has been established as the most effective antipsychotic medication for treatment-resistant schizophrenia. However, it is significantly underutilized mainly due to the risk of developing agranulocytosis and the need to frequently monitor the absolute neutrophil count (ANC).
The findings suggest that the novel, non-invasive genomic test can help physicians guide next steps for these patients, enabling them to potentially avoid unnecessary invasive procedures or accelerate time to appropriate treatment.
“These study results are highly encouraging especially given the short treatment duration of 10 days with BX004,” said Jonathan Solomon, Chief Executive Officer of BiomX. “In Part 2 of the study, BX004 showed clinically meaningful improvement in pulmonary function compared to placebo, as measured by relative FEV11 improvement (5.67% at Day 17, 1 week after end of treatment) and Cystic Fibrosis Questionnaire-Revised (CFQ-R) respiratory domain (8.87 points at Day 17) in a predefined subgroup of patients with reduced lung function.”
