MAIA Biotechnology's Experimental Cancer Drug Shows Tripled Survival Vs. Standard Chemotherapy In Pretreated Lung Cancer Patients
MAIA Biotechnology, Inc. (NASDAQ:MAIA) on Thursday revealed updated data from its THIO-101 pivotal Phase 2 clinical trial.
The trial is evaluating its lead clinical candidate, ateganosine (THIO), sequenced with Regeneron Pharmaceutical Inc's (NASDAQ:REGN) immune checkpoint inhibitor (CPI) cemiplimab (Libtayo) for advanced non-small cell lung cancer (NSCLC) who are resistant to immune therapy and chemotherapy.
As of May 15, third line (3L) data showed median overall survival (OS) of 17.8 months for the 22 NSCLC patients who received at least one dose of ateganosine (the intent-to-treat population) in parts A and B of the trial. The updated analysis demonstrates a 95% confidence interval (CI) lower bound of 12.5 months and a 99% CI lower bound of 10.8 months.The treatment has been generally well-tolerated to date in this heavily pretreated population.
At the data cutoff, the patient with the longest survival in the trial had completed 32 cycles of therapy and had 24.3 months survival.
Studies of standard-of-care (SOC) chemotherapy treatments for NSCLC in a similar setting have shown OS of 5 to 6 months.
'This new benchmark of 17.8 months median OS is nearly triple the recognized SOC data for third-line NSCLC found in the medical literature. We believe this is a substantial indicator of the potential ateganosine has to shift the NSCLC treatment landscape,' said MAIA Chairman and CEO Vlad Vitoc.
MAIA's multiple potential regulatory pathways for ateganosine could provide accelerated FDA approval and robust exclusivity in NSCLC, with a potential FDA decision as early as next year.
The company announced a new partial response (PR) was identified in a patient after 20 months of treatment. A partial response is defined as a decrease in tumor size of at least 30%.
'The patient remained on treatment and we observed stable disease for more than twenty months before the partial response was identified, highlighting the efficacy, safety and low toxicity of the treatment,' Vitoc added.
Price Action: MAIA stock is up 11.7% at $1.97 at the last check on Thursday.

S&P 500 Gains and Losses Today: Lululemon Stock Falls as Forecasts Reflect Consumer Caution
The S&P 500 added 1% on Friday, June 6, as a strong jobs report pointed to resilience in the labor market despite tariff-related concerns. After retreating from record highs over the past few sessions, shares of data analytics firm Palantir bounced back, boosted by a signal of robust AI demand. Shares of Lululemon plummeted after the apparel maker cut its outlook for the current quarter and the full year, citing soft consumer U.S. equities indexes pushed higher to close out the trading week. The Bureau of Labor Statistics reported that the U.S. economy added 139,000 jobs in May, topping economists' forecasts and helping alleviate concerns about a tariff-driven slowdown in the labor market. The S&P 500 gained 1% on Friday, closing above the 6,000-point level for the first time since February. The Dow was up 1.1%, while the Nasdaq jumped 1.2%. Shares of big data analytics software provider Palantir Technologies (PLTR) popped 6.5% higher, securing the top daily performance in the S&P 500. Positivity around its expanding government business helped lift Palantir to an all-time high on Tuesday, but before Friday's gains, the stock had been pulling back for a couple of sessions. Palantir and other artificial intelligence companies benefited from upbeat sentiment after earnings results from chipmaker Broadcom (AVGO) revealed strong AI demand. Moderna (MRNA) shares wrapped up a volatile week of trading with a gain of 5.1% on Friday. The biotech company announced at the end of last week that it had received Food and Drug Administration (FDA) approval for the use of its new COVID-19 vaccine by older and higher-risk patients. On Tuesday, Health and Human Services Secretary Robert F. Kennedy Jr. said Moderna had agreed to a placebo-controlled trial of the vaccine. United Airlines (UAL) announced a partnership with Spotify Technology (SPOT) that will allow airborne passengers to access playlists, audiobooks, and video podcasts from the streaming service on their seatback screens. United shares increased 4.8% on Friday, while rival carrier Delta Air Lines (DAL) shares were up 4.3%. Tesla (TSLA) shares advanced 3.7% on Friday as the feud between Tesla CEO Elon Musk and U.S. President Donald Trump showed signs of de-escalation heading into the weekend. The spat between the two contributed to a major drop in the electric vehicle (EV) maker's stock in the prior session. Several analysts reaffirmed their bullishness on Tesla despite the high-profile conflict, but they noted that the tensions with Trump could complicate the regulatory path for the firm's self-driving technology or risk alienating people with certain political perspectives. Lululemon Athletica (LULU) issued lower-than-expected sales and profit guidance for the current quarter and trimmed its full-year profit forecast. The maker of yoga attire and other athletic apparel noted that U.S. consumers are taking a cautious approach to spending and discussed plans to increase prices on some products as it aims to mitigate tariff impacts. Lululemon shares plunged 19.8% on Friday, dropping the most of any constituent in the S&P 500. JPMorgan and UBS analysts cut their price targets on Lululemon stock following the underwhelming outlook. Broadcom posted fiscal second-quarter sales and adjusted profit results that were roughly in line with consensus forecasts. A major year-over-year uptick in artificial intelligence semiconductor revenue helped the chipmaker achieve record quarterly revenue of $15 billion. However, Broadcom shares slipped 5% on Friday, receding from a string of record highs notched before the earnings release. Mosaic (MOS), a provider of fertilizers and other agricultural products, reduced its 2025 phosphate production guidance, citing operational issues at its U.S. facilities. Shares of Mosaic were down 4.4%.

Analyst on X: Trucking is set up for inflationary cycle
Market analyst May Ling (@MarketswithMay) recently highlighted an intriguing trend in the trucking industry through her X (formerly Twitter) post, drawing attention to logistics as a significant component of the Producer Price Index (PPI). Her observations come at a pivotal time for the transportation sector, which has experienced dramatic fluctuations since the COVID-19 pandemic. Specifically, Ling noted that within the PPI, logistics seems to be the first sector that cut capacity in response to soft demand, rather than raising prices to make up for smaller batches. 'Most producers DID NOT reduce capacity — instead, they raised prices to coincide with smaller batch sizes (mostly in goods, but also true in some services),' Ling wrote. 'This is what was causing Inflation in many areas and should be deflationary once you get volume increases.' The PPI is a critical economic indicator that measures the average change over time in selling prices received by domestic producers for their output. Unlike the Consumer Price Index (CPI), which tracks retail prices paid by consumers, PPI captures price changes from the seller's perspective. As Ling emphasized in her tweet, 'Unlike CPI, PPI is a leading indicator for inflation,' making it particularly valuable for forecasting broader economic trends before they affect consumer U.S. truckload market has undergone significant transformation since the pandemic, characterized by extreme swings in capacity, demand and pricing. Following the COVID-19 freight boom, the industry found itself with excess capacity as demand normalized and consumer spending patterns shifted. This oversupply situation was further complicated by volatile trade policies and tariff rhetoric, creating uncertainty in import patterns. As market conditions deteriorated, thousands of small and midsize trucking carriers faced unsustainable economics. According to research from freight brokerage RXO, 'the average cost to operate a truck is 34% higher over the past decade but absolute spot rates are largely the same as they were in 2014.' This economic reality triggered widespread business failures and market exits, initiating a painful but necessary adjustment mechanism to rebalance the supply-demand equation. This newfound balance has begun manifesting in key market indicators. The national average Outbound Tender Rejection Index, which measures the percentage of tendered loads rejected by carriers, climbed to 6.67% – reaching the threshold where rejections start putting inflationary pressure on spot rates. Truckload spot rates (excluding fuel) rose 9.1% year over year in the first quarter of 2025, following an 11.6% growth rate during the fourth quarter of 2024. A notable development has been the emergence of significant regional disparities. By June 2025, tender rejection rates for truckload shipments originating in the Southeast surpassed 10% – the first time in nearly three years they had reached that level. In contrast, rejection rates for freight departing the West Coast remained well below the national average. The 'interior' markets of Atlanta, Chicago and Dallas showed the tightest capacity conditions among major freight observation that 'logistics is a major component of PPI Services' highlights the sector's importance in the broader economic landscape. Her tweet identified trucking as the first area within PPI where capacity reduction has begun, potentially signaling a shift in the inflation narrative. In her analysis, Ling pointed to a 'period of reverse economies of scale' that has persisted for almost two years. She explained that inflation has been driven by 'small batches, not shortage-driven price increases,' contrary to common misconceptions. Most producers maintained capacity but raised prices to accommodate smaller batch sizes, creating inflationary pressure across goods and some services sectors. Looking forward, Ling outlined several scenarios. One possibility involves producers eventually capitulating and cutting capacity, which could become inflationary if GDP growth follows. Alternatively, rate declines might arrive in time to drive volume growth, restoring profitability before businesses make significant capacity cuts. The market trajectory for truckload rates remains 'inflationary,' according to RXO, though trade policy presents a significant wild card. Transportation prices were forecast to be significantly higher a year from now, with industry respondents returning a reading of 75 for the pricing outlook in the Logistics Managers' Index. Ling noted that demand patterns, while showing some strange variations by industry, aren't the core issue. Instead, she pointed to 'weirdly choppy purchasing behavior that is not helpful to Trucking' and emphasized the binary impact of tariffs on the sector. Ling's analysis provides a valuable framework for understanding the relationship between logistics, the Producer Price Index and broader inflation trends. By identifying trucking as the first sector where capacity reduction has begun, she offers an early signal of potential shifts in the economic landscape. The trucking market's gradual healing has finally restored equilibrium between supply and demand, enabling carriers to regain pricing power. However, as Ling cautioned, the market remains sensitive to external shocks, particularly trade policy developments and potential economic headwinds. The significant reduction in truckload capacity has made the market more responsive even to modest demand changes, positioning the sector for potential volatility in the coming post Analyst on X: Trucking is set up for inflationary cycle appeared first on FreightWaves.

RFK Jr. will ‘end the war' against alternative medicine at the FDA, from stem cell therapy to chelation. Here's what to know
Health and Human Services Secretary Robert F. Kennedy, Jr. doubled down on his support for non-pharmaceutical health treatments during a recent podcast appearance, saying, 'We're going to end the war at the FDA against alternative medicine.' Speaking on the Ultimate Human podcast with host Gary Brecka, a 'renowned Human Biologist, biohacker, and longevity expert,' according to the website, Kennedy said he would fix the U.S. Food and Drug Administration's bias against the following: stem cell treatments, chelating drugs, vitamins and minerals, amino acids, peptides, and hyperbaric chambers. 'Our position is that the FDA has a job: Just do the science on these kinds of issues and then tell the public what they've learned from the science … but don't tell physicians what they can and cannot prescribe,' he said. And as far as the patients go, he said, 'If you want to take an experimental drug … you ought to be able to do that.' RFK Jr. added, 'We don't want to have the Wild West. We want to make sure that information is out there. But we also want to respect the intelligence of the American people' to decide what treatments will benefit them the most. He acknowledged that, with this approach, there will be 'charlatans' as well as 'people who have bad results' from various alternative treatments. 'But ultimately,' he said, 'you can't prevent that either way, and leaving the whole thing in the hands of pharma is not working for us.' Brecka called Kennedy's pronouncements 'music to my ears.' Below, what you need to know about the alternative therapies RFK Jr. is advocating for. What is it: It's a way to repair diseased or injured tissue in the body using stem cells—cells that can self-renew or become other types of tissues—typically grown in a lab, manipulated, and then be implanted into the patient. What it does: Though it's considered to be largely experimental, the FDA does permit stem cell therapies for blood and immune disorders. Leukemia, lymphoma, neuroblastoma, and multiple myeloma, for example, are also often treated this way, with bone marrow treatments, which are backed by decades of science. Other types of the treatment are still in clinical trials, while more and more wellness centers are offering the treatment for unapproved reasons, using cells drawn from the patient's body and injected back in without manipulation for everything from autism and ALS to Parkinson's and better skin, according to the New York Times. Kennedy told Brecka that he received the treatment for his voice disorder, spasmodic dysphonia, and that it helped him 'enormously,' but that he had to go to Antigua to access it. Risks: For starters, wellness clinic treatments cannot guarantee they are using actual stem cell, reported the Times. And improper injections can lead to a host of terrible consequences—clots, infections, blindness, and even the formation of tumors, which the FDA warned of in 2021. What it is: Chelation involves the use of certain chemicals to remove toxic heavy metals, such as mercury and lead, from the body; all FDA-approved chelation therapy products require a prescription and can only be used safely under the supervision of a healthcare practitioner. What it does: Some alternative medicine practitioners offer chelation therapy, through pill or injection, as a way to treat Alzheimer's, autism, diabetes, high blood pressure, or Parkinson's disease, all of which are unapproved and risky. Children's Health Defense, founded by Kennedy, has written about chelation as a way to treat autism, which compares 'autism with mercury poisoning' due to childhood vaccines that contained the preservative thimerosal (largely mercury) before it was removed in 2001. Some flu shots still contain the preservative, but, says the Centers for Disease Control and Prevention, 'There is no evidence of harm caused by the low doses of thimerosal in vaccines.' Risks: The FDA warns specifically about using chelation therapy for autism, and notes, 'Chelating important minerals needed by the body can lead to serious and life-threatening outcomes.' While minor risks may include fever, headache, muscle pain, and nausea or vomiting, severe reactions range from heart failure and kidney damage to respiratory failure and seizures, according to the Cleveland Clinic. What they are: Dietary supplements in almost every letter of the alphabet, from A to zinc, are over-the-counter pills or liquids that contain nutritional boosts of vitamins and minerals. What they aim to help: Vitamin and mineral supplements aim to fill in with necessary nutrients that a person is not getting through food—though nutritionists believe that healthy food is the best source of such vitamins and minerals. Studies have found supplements may help with practically any issue under the sun—energy, heart issues, cognitive function, gut health, sleep, and more. Risks: The U.S. Food and Drug Administration regulates supplements, but doesn't approve them for safety or effectiveness before they are sold to the public. Some may cause liver damage and toxicity, while others may just be a waste of money. What it is: Amino acids are often referred to as the 'building blocks of proteins,' needed for building proteins, hormones, and neurotransmitters. are compounds that play many critical roles in your body. You need them for vital processes such as building proteins, hormones, and neurotransmitters. Amino acids are concentrated in protein-rich foods such as meat, fish, and soybeans, and foods that contain all nine essential amino acids are called complete proteins. Peptides are short proteins, and come in the form of hormones such as follicle-stimulating hormone (FSH), and creatine and collagen. What they aim to help: Amino acid supplements may help with various issues—such as L-arginine for blood flow and inflammation; tryptophan for mood and sleep; and valine, leucine, and isoleucine to help with energy and athletic performance. Taking collagen supplements may help strengthen nails and bones, while people take creatine for boosting workouts and building muscle growth. Risks: Side effects of taking either can range from toxicity and gastrointestinal issues to effects on brain function muscle protein balance. Creatine may cause muscle cramps and digestive problems (and may not have many benefits), while tryptophan may cause dizziness, headache, or nausea. And again, as with all supplements, the U.S. Food and Drug Administration regulates them, but doesn't approve them for safety or effectiveness before they are sold to the public. What it is: Hyperbaric oxygen therapy in a medical-grade, FDA-approved chamber lets you breathe pure oxygen—as opposed to everyday air, which is just 21% oxygen mixed with nitrogen. Hyperbaric oxygen is also highly pressurized, thereby allowing the lungs to take more in. Home chambers (used by folks including Lebron James, LeAnn Rimes, and Mayim Bialik), as well as those offered in many wellness clinics, do not deliver 100% oxygen. Instead, they use regular air that is 30% more pressurized than normal for what's known as 'mild hyperbarics.' What it aims to help: The FDA has been regulating HBOT chambers since 1976, and has officially cleared 13 medical conditions—such as decompression sickness, burns, radiation injury, and certain wounds—for such treatment. But it's used off-label for many other reasons, including concussions, traumatic brain injury, long COVID, age reversal, stroke recovery, fibromyalgia, and improved brain function, many of which are being looked at in ongoing clinical trials. Risks: For medical-grade chambers, risks include ear and sinus pain, middle ear injuries, temporary vision changes, and lung collapse, which is rare, according to the FDA. For mild hyperbarics, risks include potential exposure to toxic oils from some compressors, carbon dioxide buildup that brings a risk of hypoxia inside the chamber—or, according to some experts and a body of inconclusive evidence, that the treatment may simply be ineffective.
