Addiction clinics see rising cases of kratom and 7-OH withdrawal

Theresa Gaffney·STAT News·28m ago

Addiction clinics around the country are seeing a growing number of cases related to gas station products made from the kratom leaf and its derivatives. At the telehealth addiction clinic Boulder Care, for example, people who report using kratom products constituted 3% of all new patients in September 2025. By July 2026, that number was 8%, and in August, it jumped to 14%. Read the rest…

Tell HN: An inside view of Montana's new biotech law

niklas_anzinger·4d ago5pts

Montana passed a law called SB535. It builds on right-to-try (pre-approval access with informed consent, Phase 1 safety data etc.) but goes much further, fixing problems with those laws.Alex Tabarrok called it "the most important regulatory innovation in drug approval in my lifetime" (https://marginalrevolution.com/marginalrevolution/2026/06/mo...). Was posted here but died in /new (https://news.ycombinator.com/item?id=48559525). The mods suggested this post.I contributed ideas to the law and am now implementing it through my company. I invested in biotech for years and watched companies struggle. I built the biotech ecosystem in Prospera as an alternative, concluded it was too early, and now think Montana is the best place to prove this.Why this exists: When FDA approves a bad drug, heads roll. When it delays a good one, the deaths are statistical and nobody gets blamed ("invisible graveyard"). So the incentive is overcaution, which is why the cost per approved drug has roughly doubled every 9 years for decades ("Eroom's Law"). Founders are in the "Valley of Death" around Phase 1: grants are no longer available, and commercial money wants assurance the drug will pass the next trial. Only ~10% of post-Phase 1 drugs get approved, but 68% of failed trials don’t stop because they found lack of safety or efficacy but commercial reasons (Williams et al., PLOS ONE 2015). Federal Right to Try and Expanded Access haven't fixed this. Federal reform is super-hard.What Montana allows: A physician can give an experimental treatment outside a trial if: it completed FDA Phase 1 under an active IND; a state-registered private review board (ETRB) approved the protocol; it's delivered at a state-licensed clinic; consent exceeds the federal standard & adverse events need to be reported. The key is: sponsors and clinics can charge.Why this time it's different: The risk-reward ratio is what's broken. Right to Try and Expanded Access don't let sponsors charge, so treating a patient is risk plus expense. Montana is the first state law where sponsors of IND-stage drugs can price in that risk. Trial recruitment today is a price-control system: per-patient cost is around $50-100k, typically has a ceiling upward on what it can pay patients ("undue inducement") and a floor downward (no profit, only at cost in RTT / EA). Montana removes both (I know this will lead to lots of debate, let’s have it.)So this is not a free for all, the additional liberties come with tough oversight. An ETRB is Montana's version of an IRB: safety review, consent, mandatory outcome reporting, and you can't withhold safety information from patients. That’s the truth-funding mechanism.What companies can do now: If you have a Phase 1 asset stuck in the Valley of Death: treat patients, negotiate payment, get real-world data, use it to sharpen your Phase 2/3 design.Disclosure: my company formed the first ETRB. The model is review fees, like an IRB; no equity in applicants, no payment by outcome; COI policy and board bios public; decision letters published with applicant consent; annual outcome report required.Objections:- Someone gets hurt? Same as trials and ordinary care: US legal system, legal recourse.- FDA shuts it down? They haven't said they won't, but historically FDA goes after grey-market clinics, not state laws; we're asking for safe harbor, but some companies aren't waiting.- Snake oil? Bad actors want to fly under the radar, and Montana makes that hard.What's needed: Biotechs with Phase 1+ assets willing to move before full FDA assurance, to build the evidence that gets the agency on board - the point is not to skip FDA, but to reduce the cost of data. And ex-FDA reviewers, IND operators, IRB members telling us where this breaks.Happy to answer anything.

The Big Holes in Wearable Heart Rate Variability And Readiness Scores

Eric Topol·Eric Topol·1d ago

On September 9th, Apple announced it was revamping its Apple Watch Health Sensing System, rolling out a Readiness score (0 to 10), and increasing the frequency of heart rate variability (HRV) outputs 24-fold. This can be viewed as upping its competition with various other consumer wearable sensors. These “readiness scores” as a composite of multiple metrics, with heart rate variability (HRV) being front and center for most. The majority of Americans are now using wearable sensors, which equates ...

"SpudCell will replicate continuously by 2030" | Kate Adamala

Asimov Press·Asimov Press·3d ago

About a month ago, chemists made a synthetic cell capable of eating, growing, and dividing for at least five generations. They called it SpudCell, and the lead author, Kate Adamala of the University of Minnesota, thinks it might be able to reproduce perpetually by 2030; a feat that, she argues, would finally make SpudCell “alive.”I flew to Minnesota and interviewed Adamala for about three hours. First, I wanted to understand the bottlenecks with SpudCell. What engineering changes will they make ...

STAT+: FDA approves a new gene therapy for Sanfilippo syndrome, an ultra-rare disease

Jason Mast·STAT News·3d ago

The Food and Drug Administration on Thursday approved a new gene therapy for Sanfilippo syndrome type A, an ultra-rare disease sometimes known as childhood Alzheimer’s. The therapy, called Fayuvi, was developed by Ultragenyx. It is the first drug specifically approved to treat Sanfilippo. Ultragenyx did not immediately release a price. “It’s hard to overstate what this approval would mean for everybody who is living with this really horrific disease and watching their children suffer and pass aw...

STAT+: Why do ‘never-smokers’ get lung cancer? In some cases, rare genetic variant may be a factor

Andrew Joseph·STAT News·3d ago

For years, researchers have known that, among people diagnosed with lung cancer, the prevalence of nonsmokers has been increasing. But they have been trying to determine what factors — whether genetic, environmental, or something else — might put these “never-smokers” at heightened risk.  Now, researchers have identified a very rare genetic variant that is associated with 25-fold higher odds of lung cancer, they reported in the journal Science on Thursday. In the U.S., the variant is far more co...

STAT+: Scientists made mice with half a brain. Then they filled them with human organoids

Megan Molteni·STAT News·4d ago

For the last decade, scientists have been steadily getting better at growing “cerebral organoids,”  miniature, three-dimensional brain-like structures, from human stem cells in the lab. Now, a group from Stanford University has found a way to advance their usefulness for studying brain development and disease — by instead growing them inside mice that have had large parts of their own brains genetically removed.  Neuroscientists say these “neuro-chimeric” mice, whose brains are half-human — by v...

STAT+: Medicare to expand its pilot that pays for technology to manage chronic diseases

Mario Aguilar·STAT News·5d ago

A Medicare experiment in paying for technology to help people manage chronic conditions has just barely gotten underway, and officials are already moving to expand it. Announced last year, the ACCESS model will pay approved companies to manage certain chronic conditions, including diabetes, high blood pressure, chronic musculoskeletal pain, depression, and anxiety. The model introduces outcome-aligned payments, in which providers are paid more if their patients’ conditions improve. Regulators on...

STAT+: Vera kidney drug Trutakna shows strong final results in Phase 3 trial

Adam Feuerstein·STAT News·5d ago

Vera Therapeutics said Tuesday that its recently approved drug Trutakna stabilized kidney function and reduced the risk of kidney-related death and other complications in patients with a chronic autoimmune kidney disease, according to final, two-year results from a Phase 3 clinical trial.  In July, the Food and Drug Administration granted accelerated approval to Trutakna for the treatment of IgA nephropathy, or IgAN, a disease caused by the buildup of immune antibodies in the kidneys. The condit...

Exercise — and echocardiograms — in space protected astronauts’ hearts in study

STAT+: Definium’s LSD therapy eased anxiety in second large trial

Elaine Chen·STAT News·6d ago

Definium Therapeutics said Monday that its LSD therapy helped patients with anxiety in a second late-stage trial, setting up the company to seek the first approval of a psychedelic drug for anxiety. In the 12-week trial, patients taking a 100-microgram dose of the drug, called DT120, experienced a 9.8-point drop on a test called the Hamilton Anxiety Rating Scale, while those on placebo experienced a 4.7-point drop. The difference of 5.1 points is similar to what was seen in Definium’s first late...

Platinum-based chemotherapy in childhood causes mutations that age the liver

Annalisa Merelli·STAT News·10d ago

Platinum-based chemotherapy — in particular cisplatin and carboplatin — are a lifeline for children with certain cancers. These treatments, for instance, transformed the prognosis of hepatoblastoma, a rare cancer of the liver that is the most commonly diagnosed in childhood, from a five-year survival rate of 20% to more than 80% for localized tumors.  However, these medications work by damaging the DNA of cancer cells, and they are also known to cause mutations in the DNA of healthy cells, poten...

STAT+: Novartis’ experimental cardiovascular drug fails a pivotal study

Andrew Joseph·STAT News·16d ago

A closely watched cardiovascular drug from Novartis failed in a pivotal study, the company said Friday, a major blow to the firm and to efforts to target a common heart disease risk factor.  The drug, called pelacarsen, had shown in earlier trials that it could drastically lower levels of what’s called Lp(a), a little blob of lipids and proteins that at elevated concentrations increases the likelihood of severe heart problems. But Novartis said that in the Phase 3 HORIZON trial, pelacarsen faile...

Why are drug overdose deaths declining?

Theresa Gaffney·STAT News·18d ago

From 2021 to 2023, more than 105,000 people in the U.S. died from a drug overdose each year — tens of thousands more than the already high rates seen in the lead-up to the Covid pandemic. Then, suddenly, the death rates dropped. In 2024, U.S. overdose deaths decreased 27%. Preliminary data from 2025 show another meaningful drop, though overdose mortality is still quite high. Other countries with major overdose problems also saw fewer deaths: In Scotland, there was a 13% decrease in 2024, and in ...

STAT+: NIH proposal to cap research grants draws mixed reception, agency says

A personalized cancer vaccine developed by Moderna and Merck has generated widespread enthusiasm since the companies announced last week that it had succeeded in a late-stage trial. If regulators ultimately approve it, the treatment will be a triumph of immunology and cancer biology. But it may also be a triumph of the algorithm.

Focal therapy for localized prostate cancer has divided physicians. Will new data change minds?

Annalisa Merelli·STAT News·1mo ago

For most localized solid tumors, it’s common for surgeons to try to preserve as much of the diseased organ as possible, removing only the cancer along with some healthy tissue surrounding it to avoid further spread. But for prostate cancer, treatment is usually all or nothing. Except for patients with low-grade disease that’s unlikely to turn deadly, the whole gland gets removed, or irradiated. The long-term consequences can be serious, notably incontinence and erectile dysfunction.  A less aggr...
