Diversity in clinical trials is crucial for ensuring that new medical treatments are safe and effective for all populations. Last year, the FDA released draft guidance that aims to improve the enrollment of historically underrepresented populations in clinical trials.

Demand is growing for more transparency and diversity in clinical trials, according to Erin Leckrone, senior director of clinical trials at Be The Match BioTherapies. Additionally, a growing number of stakeholders are stepping forward to promote diversity. “The COVID pandemic really amplified a lot of people’s voices in this space,” she said.

A growing number of stakeholders have stepped forward to demand better diversity in clinical trials and to understand “what data is actually collected as part of the clinical trials,” Leckron said. Those players range from regulatory agencies like the FDA to clinical trial …

At the Nvidia GTC 2023, DeepMind’s Founder and CEO, Demis Hassabis, provided an in-depth look into the seismic potential of their protein folding AI system, AlphaFold. Hassabis said AlphaFold was a contender for the organization’s “biggest project to date.”

Hassabis noted that DeepMind’s AlphaFold has made strides in addressing the protein folding problem, a challenge that has stumped scientists for more than five decades. The protein folding problem involves predicting the 3D structure of proteins solely from the amino acid sequence. Until AlphaFold, determining a protein’s structure was a complex and time-consuming process, often taking years of experimental work.

At the end of 2022, the company announced that it updated AlphaFold with the structure predictions of more than 200 million proteins.

Hassabis explained the enormity of the challenge, …

Engineers at MIT designed a new way to trigger cells that could lead to targeted therapies for cancer and other diseases.

Using an RNA sensor for the trigger, the researchers ensure that synthetic genes activate only in specific cells. They demonstrated that the sensor could accurately identify cells expressing a mutated version of the p53 gene, which drives cancer development. Additionally, they found they could turn on a gene encoding a fluorescent protein only within those cells.

With this approach, the engineers feel they can develop sensors to trigger production of cell-killing proteins in cancer cells, sparing healthy cells, too. They see the possibility of developing treatments for other diseases, too…

Non-hallucinogenic LSD derivative reduces depression symptoms in preclinical studies

Vancouver-based biotech firm BetterLife Pharma (OTCM:BETRF) is working on a non-hallucinogenic LSD derivative for treating neuropsychiatric and neurological disorders.

Known as BETR-001 (2-bromo-LSD), the compound is also not controlled. Conversely, LSD, like other serotonergic hallucinogens, is a Schedule I compound. That status makes it difficult and expensive to research for potential medical uses.

BetterLife announced recent positive results from preclinical studies for the LSD derivative in reducing depressive symptoms in rats.

The research has been published in Cell Reports.

In vitro studies found that 2-bromo-LSD promoted dendritogenesis and spinogenesis in rat cortical neurons. Additionally, in vivo studies found that it produced active coping behavior and reversed chronic stress deficits. Those effects are likely dependent on activation of the 5-HT2A serotonin receptor. The study concluded that 2-bromo-LSD appears to have potential as a t…

The generic and biosimilar company Sandoz, a Novartis (NYSE:SIX) subsidiary, has received FDA approval for its Humira biosimilar Hyrimoz (adalimumab-adaz) injection. AbbVie’s (NYSE:ABBV) megablockbuster Humira is a biologic medication with indications for an array of autoimmune conditions, including rheumatoid arthritis, Crohn’s disease and psoriasis. Sandoz’s biosimilar will likely be priced significantly lower than Humira’s. This fact could dramatically impact the marketplace for AbbVie’s version of the drug, as it is priced lower and could lead to a decrease in market share for Humira.

The FDA approved Sandoz’s Hyrimoz, a biosimilar of AbbVie’s Humira, to treat seven conditions: rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis,…

A gene therapy for spinal muscular atrophy (SMA) patients is making waves. Novartis (NYSE:NVS) revealed new long-term data highlighting the durability of Zolgensma (onasemnogene abeparvovec) up to 7.5 years after a single treatment. The data comes from two long-term follow-up studies, LT-001 and LT-002, which examined a range of patient populations and demonstrated a positive overall benefit-risk profile. LT-001 is an ongoing 15-year long-term follow-up study of patients who completed the phase 1 START study. More than 3,000 children have been treated with Zolgensma in clinical trials, managed access programs and commercial settings.

Novartis expects Zolgensma to eventually generate $1.5–2 billion, according to BioPharma Dive. NVS shares were up 1 percent to $83.01 today after announcing the new data.

FDA approved Zolgensma (onasemnogene abeparvovec-xioi) in 2019 for chi…

QurAlis targets UNC13A RNA mis-splicing in ALS and FTD with novel FlexASO platform

QurAlis, a privately-held company specializing in precision medicines for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases, has debuted its latest program. This initiative targets UNC13A RNA mis-splicing, a critical gene alteration present in ALS and frontotemporal dementia (FTD). FTD has recently gained renewed attention following the disclosure of Bruce Willis’ diagnosis of the condition. UNC13A is a vital regulator of neurotransmitter release at synapses, and the genetic alteration resulting in mis-splicing is estimated to occur in 58% of ALS patients and up to half of FTD cases.

To tackle this gene alteration, QurAlis has developed its proprietary FlexASO splice modulator platform. This technology uses antisense oligonucleotides (ASOs) to correct mis-splicing, restore UNC13A protein production, and reduce cryptic exons that may contribute to disease progression. Kasper Roet, QurAlis CEO, explained that “FlexASOs operate on the s…

Epilepsy is a brain disorder that triggers recurring seizures. It is the fourth the most common neurological disorders in the world, according to the Epilepsy Foundation. The Centers for Disease Control and Prevention estimates that 65 million people worldwide have active epilepsy. In 2015, 1.2% of the total U.S. population — 3 million adults and nearly 500,000 children — had active epilepsy.

There are many different causes of epilepsy, including genetics, head trauma, brain abnormalities, infection, prenatal injury and developmental disorders, such as autism.

Seizure symptoms vary greatly and can manifest in a person as uncontrollable limb movements, staring, muscle stiffness, confusion and loss of consciousness or awareness.

These symptoms are not mutually exclusive. Some patients with epilepsy experience multiple types of seizures.
