Emerging Options in Second-Line Therapy for Metastatic NSCLC
Dr Tom Stinchcombe of Duke University in Durham, North Carolina, discusses ADCs, checkpoint inhibitors combined with tumor treating fields (TTF) therapy, and other targeted therapies being evaluated as second-ling therapies for metastatic NSCLC.
Dr Stinchcombe first describes telisotuzumab vedotin, a c-Met-directed antibody and microtubule inhibitor conjugate indicated for metastatic NSCLC patients with high c-Met protein overexpression. The drug received FDA-accelerated approval on the basis of the LUMINOSITY trial, in which telisotuzumab vedotin monotherapy provided clinically meaningful response and progression-free survival in this population.
He then describes TTF therapy, which delivers electrical impulses to the tumor site to disrupt processes critical for cancer cell division.
The LUNAR trial showed the benefit of TTF plus checkpoint inhibition in second-line treatment of metastatic NSCLC, suggesting an additive benefit of this combination.
Finally, he discussed two trials showing second-line therapies for patients with KRAS G12C mutations, in which sotorasib and adagrasib have shown potential benefit over docetaxel in this population.

Another hole has formed at Yellowstone National Park, geologists say
More geological changes are occurring at Yellowstone National Park, as another hole forms in one of the park's basins. The hole is a blue water spring, discovered by geologists in April as they conducted routine maintenance of temperature logging stations at Norris Geyser Basin, according to the U.S. Geological Survey. MORE: Hidden magma cap discovered at Yellowstone National Park The pool, located in the Porcelain Basin sub-basin west of a patch of vegetation known as "Tree Island," was not there during their last visit to the area in the fall, according to the USGS. The water is light blue in color and is about 1 foot deep below the rim. It's geological features indicate it formed as a result of a hydrothermal explosion -- an event caused by pressure changes that result from the transition of liquid water to steam, according to the USGS. MORE: Researchers working to save whitebark pine, a declining keystone tree species in the greater Yellowstone area The pool measures about 13 feet in diameter and is surrounded by numerous small rocks about 1 foot across. The rocks are covered by light gray, sandy mud. It is "not surprising" that a hydrothermal explosion occurred at the site, as it has happened several times in recent decades, according to the USGS. The North Geyser Basin is the "most dynamic" area in Yellowstone, the agency said. High-resolution satellite imagery indicates that the hole was not present on Dec. 19, but images taken on Jan. 6 show a depression that had formed in the area. By Feb. 13, the pool had been filled with water, the satellite images show. More will hydrothermal explosions will likely be recorded, as a monitoring station installed in 2023 can detect geophysical data indicating an explosion. MORE: Yellowstone visitors are getting so comfortable with approaching wildlife that park officials are asking them to stop In April 2024, a "small" explosion at the Porcelain Terrace left a crater measuring several feet across in diameter, according to the USGS. A hole that formed in Yellowstone's Biscuit Basin, near Old Faithful, in July 2024 was also attributed to a hydrothermal explosion, according to the National Park Service. While that hole likely formed in a single major explosive event, the newest thermal feature appears to have formed by multiple small events that initially threw rocks but later threw silica mud a short distance, creating a small pit that became filled with silica-rich water. MORE: Yellowstone supervolcano has a lot more magma than previously thought: Scientists Geologists estimate that the feature probably started to develop on Dec. 25, with further activity occurring through late January and early February, according to the USGS. Beneath Yellowstone National Park lies a complex and extensive volcanic system. The park is thoroughly monitored by the USGS and the Yellowstone Volcano Observatory.

The Big Beautiful Bill Is Bad for Americans' Health and Wallets, Study Finds
The 'Big Beautiful Bill' is now law, and it's poised to wreak plenty of destruction. Research out today finds that the policy changes will lead to thousands more deaths annually, as well as harm the financial health of rural hospitals. Epidemiologists at the University of California, San Francisco, and elsewhere conducted the study. They found the Medicaid cuts caused by the Big Beautiful Bill will cause many avoidable hospitalizations and deaths, put dozens of rural hospitals at high risk of closing, and ultimately leave a big dent in the U.S. economy as a whole. The findings are only the latest to highlight the likely damage from the Trump administration's now crowning achievement. 'This analysis suggests substantive negative health and economic impacts from provisions in the current Medicaid reform bill,' the authors wrote in their paper, published Wednesday in JAMA Health Forum. Elon Musk Rekindles Trump Criticism, Attacks 'Big, Beautiful Bill' The One Big Beautiful Bill Act—signed into law by President Donald Trump on July 4—extends the 2017 tax cuts passed during Trump's first term and enacts many of the administration's other priorities, including increased defense spending. It was crafted as a budget reconciliation bill, which allowed Republicans to pass it through the Senate with a simple majority. To offset some of its added expenditures, the bill includes provisions designed to trim spending across several programs, most notably Medicaid. These provisions include tighter restrictions on Medicaid eligibility, work requirements for non-disabled adults, and the delay of Biden-era regulations to simplify and expand Medicaid access. The Congressional Budget Office previously projected that these changes would reduce Medicaid spending by roughly $700 billion between 2026 and 2034 and cause 10.3 million people to leave Medicaid by 2034, including 7.6 million who would become uninsured entirely. To come up with their estimates, the study authors analyzed past research looking at the aftereffects of losing health care coverage on people, hospitals, and the economy. Under the CBO's projections of lost coverage, they estimated that nearly 95,000 more hospitalizations in the U.S. would occur annually by 2034, along with 1,500 excess deaths a year. 1.6 million people annually would also delay medical care due to cost, and nearly 2 million would fail to take their medications as instructed. The researchers further calculated the bill would cause many rural hospitals to lose revenue from losing patients covered by Medicaid and having to pay for uninsured patients instead. They estimated that 101 rural hospitals would be at high risk for closure by 2034. The losses in coverage were also estimated to result in 302,000 lost jobs annually by 2034, as well as $135.3 billion less money being pumped into the economy every year, including $11 billion lost in state and local taxes. These coverage losses could additionally generate $7.6 billion in medical debt by 2034. Trump's 'Big Beautiful Bill' Will Literally Kill, Study Warns Other studies have mapped out the health costs of the Big Beautiful Bill, but the study researchers say their analysis takes an even deeper look into the total fallout that will come from it. 'The study critically is peer-reviewed and uses evidence from multiple rigorous studies to create a hopefully more credible assessment of impact, specifically looking beyond coverage losses alone to other secondary impacts on healthcare entities and local economies,' lead author Sanjay Baju, an epidemiologist and physician at UCSF, told Gizmodo. Though the bill is now signed into law, there may yet be further changes made to Medicaid. But Baju and his colleagues don't expect any such changes to significantly alter their estimates. If anything, the numbers may be too rosy. It's possible that even more people will lose their Medicaid coverage, the researchers note, and they didn't analyze the impact of possible negative changes to Medicare that could also be set into motion by the bill. While these provisions aren't scheduled to come into effect for some time, some rural hospitals have already blamed the law for their closures. Baju says that it's still possible to mitigate at least some of the harms caused by the bill, such as through added private funding. But the reality of the situation is grim enough that even many of its supporters are scrambling to run damage control. Health and Human Secretary Robert F. Kennedy recently denied outright that the law will cause any Medicaid cuts, for instance, while Senator Josh Hawley (R-Montana) introduced legislation Tuesday to prevent the Medicaid changes he voted for.
