The Yaya Foundation recently achieved a milestone in advancing towards treatments for 4H leukodystrophy when it successfully developed a mouse model. It reflects a broader effort that has allowed the organization to drive towards the development of a gene therapy to treat the rare, neurodevelopmental. We spoke to Ron Garber, co-founder and board president of the Yaya Foundation, about 4H leukodystrophy, how the organization built a research agenda, and the rapid progress it has made.

In 2021, the U.S. Food and Drug Administration notified Stealth Biotherapeutics it would not consider its application seeking approval for elamipretide as a treatment for the ultra-rare mitochondrial disease Barth syndrome. The agency wants the company to produce evidence of the drug’s efficacy in a larger population of Barth syndrome patients than it studied, but the company believes it has exhausted the population in the United States of patients who fit the clinical trial criteria. Patients h...

Scaling the production of biotherapeutics is challenging and requires more than just multiplying the ingredients in a recipe. That’s true for gene therapies as well where simply changing the nucleic acid of the payload can have dramatic effects on the product. Form Bio is seeking to address the challenges of making genetic medicines by leveraging AI to accelerate the development of cell and gene therapies. We spoke to Claire Aldridge, chief strategy officer for Form Bio, about the challenges of ...

Finding a diagnosis for a child with a rare condition can be challenging, even when his mother is a genetic counselor. Danielle Bonadies’ son Ethan was born with a brown birthmark known as a café au lait spot. But as the spots proliferated over the next few months, his pediatrician recognized it as a potential sign of a rare, genetic disorder. It wasn’t until Ethan was 2 that genetic testing led to a formal diagnosis of neurofibromatosis type 1, a genetic condition that leads the development of ...

Protein misfolding is an underlying issue for many diseases, including lysosomal storage disorders and some neurodegenerative conditions. When a protein misfolds, its three-dimensional structure is disrupted, and it can no longer function properly. Gain Therapeutics is using its AI-driven discovery platform to identify novel targets to fuel a pipeline of therapies that focus on enzymes involved in rare genetic diseases, but that also share genetic profiles with more prevalent ones. We spoke to M...

Antibodies play an important role in the protective immune response. In some situations, though, such as autoimmune diseases, antibodies can cause harm by attacking healthy tissue. Hansa Biopharma has developed an antibody-cleaving enzyme technology platform to target pathogenic antibodies involved in autoimmune disease, organ transplantation, and gene therapies. Its lead experimental therapy, imlifidase, is designed to inactivate immunoglobulin G antibodies through a single intravenous treatmen...

Microglia are specialized immune cells in the central nervous system that act as sentinels to maintain healthy brain function. They protect the brain against processes that can ultimately lead to neurodegeneration. Vigil Neuroscience is developing precision medicines designed to target microglia and restore and enhance the performance of these cells when they fail to act as they should due to disease. The company’s lead program is in development as a treatment for ALSP, a rare, genetic, neurodeg...

Cystic fibrosis is a rare disease that has been an area of significant innovation. New therapies have provided life-changing treatments for most patients, but about 10 percent of people with the condition don’t benefit from these treatments because of the specific mutations underlying their condition. We spoke to Jamie Chang, senior medical director at the contract research organization Rho, about the advances that have been made to treat cystic fibrosis, the treatment gap that remains, and what...

At 41, Bill Potts received a diagnosis of thyroid cancer. He listened to the recommendations from his primary care physician and didn’t seek out a second opinion. It was only six months later, during a follow up visit when his doctors wanted to repeat his treatment with radioactive iodine that he began to ask questions and started to advocate for himself. He now says he would likely be dead had he not sought out a second opinion at that time. He’s since learned a lot about advocating for himself...

Regulatory T cells target systemic inflammation and neuroinflammation, but when they fail to function properly, they can drive serious health conditions including neurodegenerative, metabolic, and autoimmune diseases. Coya Therapeutics is developing a pipeline of therapies designed to restore the ability of Tregs to modulate the immune system and reduce inflammation. The company’s lead experimental therapy is a combination of two biologics designed to treat ALS by boosting anti-inflammatory Treg...

Cristóbal Baca and Ana Ortiz came to New Mexico in 1600. Today, they have as many as 5 million descendants. A four-year effort involving community volunteers and workers, medical professionals, researchers, and families across New Mexico unraveled what had been a long-standing medical mystery. It turns out Baca and Ortiz are the source of a founder mutation for cerebral cavernous malformation, a sometimes-hereditary illness that causes the development of abnormal blood vessels in the brain and s...

CDKL5 deficiency disorder (CDD) is a serious and rare, genetic condition characterized by early onset and difficult to control seizures, as well as severe neuro developmental impairment. Last year, the U.S. Food and Drug Administration approved Marinus Pharmaceuticals Ztalmy to treat seizures associated with CDD, the first FDA approved therapy for the condition.

Pulmonary arterial hypertension is a rare and progressive condition characterized by high blood pressure in the arteries of the lungs due to their narrowing or a blockage. This causes the heart to work harder to pump blood and leads to heart failure, the need for lung transplantation, and death. Aerami is developing an inhaled form of the targeted cancer therapy imatinib as a treatment for PAH. We spoke to Josh Ziel, chief operating officer and interim CEO of Aerami, about pulmonary arterial hyp...

Patients may be the experts on their own conditions, but data that captures health-related quality of life is often underutilized in research. The PKD Foundation is working with IQVIA to create a registry of patients with autosomal dominant polycystic kidney disease, a rare kidney condition. The ADPKD registry focuses on patient-reported, health-related quality of life data. The organization believes the registry will not only provide new insights into the condition but help with the design of e...

Mary Morlino knows what it’s like to search for information and resources for a loved one with a rare disease or yourself. She had two nephews who were diagnosed with the rare neuromuscular disease Becker muscular dystrophy and later she was diagnosed with the rare autoimmune condition sarcoidosis. She now performs that search for information and resources professionally, so others don’t have to do so. Today, Morlino serves as Global Genes’ RARE Concierge Patient Services manager.

Our interactions with the environment can have unexpected effects on our genes and trigger a biologic response that leads to the onset of disease. These interactions can also leave a measurable record in what’s referred to as the exposome. LinusBio, which emerged from the exposome laboratory at Mount Sinai Health System, has developed a test for autism that relies on analyzing a single strand of hair. The company said the test is capable of diagnosing autism at birth. We spoke to Manish Arora, f...

About 10 percent of children who are diagnosed with hearing loss at birth have an auditory neuropathy that is usually due to a genetic cause. One of the most common genetic causes of hearing loss is due to a mutation of the otoferlin gene, which encodes for a protein that enables communication between the sensory cells of the inner ear and the auditory nerve. Decibel Therapeutics is developing an experimental gene therapy intended to restore hearing in patients with a mutation of the otoferlin g...

While there is growing ability to pursue the development of therapies for ultra-rare diseases, they remain challenging because of economics. One major barrier is the difficulty in getting reimbursement for therapies in the absence of well-powered clinical trials that recruit enough participants to satisfy payors demands for adequate proof of the value of a therapy. The Muscular Dystrophy Association, earlier this year, awarded the nonprofit biotechnology Cure Rare Disease a grant to research nov...
