Drug Industry Taking Bigger Role in Clinical Cancer Trials

Clinical trials sponsored by Big Pharma enrolled eight times as many patients as U.S.-government trials did between 2018 and 2022, new research shows.

The study -- conducted by researchers at Fred Hutch Cancer Center in Seattle -- underscores the lack of investment in federally funded studies and a growing reliance on industry research. The magnitude of the gap researchers identified took...

Just 1 in 20 Animal Studies Yield Treatments That Make it to Humans

Animal studies are often considered a first step in finding new drugs and treatments for human diseases, but a new review has discovered that precious few actually produce real-world therapies.

Only 5% of therapies tested in animals wind up being approved by regulators for human use, according to an analysis of 122 articles involving 54 different diseases and 367 potential treatments.

One Neurological Factor Keeps Black, Hispanic Patients From Alzheimer's Clinical Trials

Black and Hispanic patients with Alzheimer's disease are greatly underrepresented in clinical trials, even though they're more likely to get dementia than whites.

However, racial discrimination may not be driving this disparity, a new study finds.

Instead, Black and Hispanic people are being judged in...

Moreover, enrollment in cancer treatment trials wa...

Experimental Drug Could Rein in Epilepsy Seizures

For people with tough-to-treat epilepsy, seizures can be both frightening and dangerous, but a new experimental pill may bring significant relief to over one-third of them.

Dubbed XEN1101, the new drug reduced the frequency of seizures by more than 50%, or even eliminated them, in some patients with focal epilepsy who did not respond to an average of six other drugs.

"I am predictin...

Ketamine Nasal Spray Shows Promise Against Tough-to-Treat Depression

A nasal spray containing a ketamine derivative appears to beat one of the standard drugs used for people with difficult-to-treat depression, a new clinical trial has found.

The trial, of nearly 700 people with treatment-resistant depression, found that esketamine nasal spray was more effective at sending patients into remission than a standard oral drug called quetiapine (Seroquel).

Stem Cell Therapy Could Be Breakthrough Against Type 1 Diabetes

People with type 1 diabetes lack functional islet cells in their pancreas to produce the hormone insulin and must take daily insulin via injections or a continuous pump to compensate.

Experimental Shot Given Every Six Months Controlled High Blood Pressure in Early Trial

Every day, millions of people must take one or more pills to control their blood pressure and reduce their risk for heart attack or stroke, but if new research pans out, some may be able to scrap their pills for a twice-yearly shot with the same benefits.

Given as a shot every six months, zilebesiran suppresses the gene that produces a hormone called angiotensin that causes blood vessels ...

Experimental Alzheimer's Drug Slows Thinking Declines in Late-Stage Trial

Another experimental drug meant to slow the damage of Alzheimer's appears poised to join a growing arsenal of new treatments for this memory-robbing disease.

In research published online Monday in the Journal of the American Medical Association and presented simultaneously at the Alzheimer's A...

Low-Dose Eyedrops No Better Than Placebo for Nearsightedness Among Kids

Low doses of the eyedrops ophthalmologists use to dilate your pupils during an eye exam are not able to slow the progression of nearsightedness (myopia) in children, a new clinical trial has found.

Atropine eyedrops at a concentration of 0.01% did not outperform placebo drops in slowing either myopia progression or elongation of the eye among children after two years of treatment, the stu...

The U.S. Food and Drug Administration on Thursday gave full approval to the Alzheimer's drug Leqembi, clearing the way for insurance coverage of the pricey drug.

"The full FDA approval will open the floodgates for people with early Alzheimer's to get this drug. It's a big deal because it's very expensive at $26,500 per year,"

    • Antibody Treatment Could Fight Rare But Deadly Bile Duct Cancers

    Patients with bile duct cancer might soon have an additional treatment available to them, thanks to a newly discovered tumor target.

    Some bile duct cancers are driven by a mutated HER2 gene, which has also been implicated in cancers of the breast, esophagus and prostate, researchers report in a new study.

    An experimental drug targeting HER2 mutations, zanidatamab, produced powerful ...

    More Evidence Gene Therapy Might Cure Sickle Cell Disease

    A clinical trial that's attempting to discover a cure for sickle cell disease has found a new gene therapy to be safe and successful in four patients.

    "New treatments like this are critical for people who have sickle...

    Diabetes Med Metformin Might Help Prevent Long COVID

    A safe, generic diabetes pill can help people avoid long COVID, a new clinical trial shows.

    Metformin cut the risk of long COVID by about 40% for patients who received a two-week course of the drug while battling their infection, the researchers reported.

    The results were even more dramatic if COVID-19 patients began taking metformin soon after infection. Starting on the drug w...

    Patients With Bladder Cancer May Avoid Removal of Extra Lymph Nodes, Study Finds

    For years, doctors have thought that a more extensive surgery that removes a wider swath of lymph nodes was the best option for certain patients with bladder cancer. Now, a new clinical trial is upending that belief.

    Researchers found that the strategy -- known as extended lymphadenectomy -- was no better than standard surgery at prolonging patients' lives or the amount of time they live...

    Gene-Targeted Drug Tagrisso Cuts Death Rate in Half for Patients With Early-Stage Lung Cancer

    Once-a-day use of the targeted cancer pill Tagrisso (osimertinib) cut the five-year death rate in half for a subset of patients with early-stage lung cancer, a new clinical trial shows.

    The results could have major implications for patients whose cancers carry a mutation in a gene known as EGFR, which is implicated in the out-of-control cellular growth driving a tumor. Tagrisso appears to...

    Could a Nitroglycerin Patch Ease Hot Flashes?

    A new study on using nitroglycerin patches to help women with frequent hot flashes caused by menopause has delivered mixed results.

    If the device proves out in a larger trial, it cou...

    Software Bias Misses Lung Problems in Black Men, Study Finds

    A common test for lung function may be missing lung problems in Black men, leading to under-diagnosis and insufficient care.

    Though Often Prescribed, Diuretic Pills May Not Prevent Kidney Stones

    A new study is raising questions about the effectiveness of medications long used to prevent painful kidney stones, but experts say there's no reason for patients to toss their prescriptions out at this point.

    'Neuroprotectant' Drug Could Boost Outcomes After a Stroke

    Using a "neuroprotectant" drug alongside the standard surgical removal of a clot may slash the risk of death and disability following a stroke, a new study finds.
