Sarepta shares slump after reports of third patient death this year
The patient was enrolled in an early-stage study testing Sarepta's gene therapy to treat a condition called limb-girdle muscular dystrophy, according to a Bloomberg report, which cited a company spokesperson. STAT news reported that the patient was a 51-year-old man who died last month from acute liver failure.
Two teenage boys, who couldn't walk independently, died earlier this year from liver failure after they received Sarepta's gene therapy Elevidys, approved to treat a rare condition called Duchenne muscular dystrophy.
Sarepta and the Department of Health and Human Services did not immediately respond to a Reuters request for comment outside of their business hours.
The fatalities have brought Sarepta under heightened regulatory scrutiny, and cast doubts on the safety and future demand for Elevidys.
William Blair analyst Sami Corwin said this could amplify patient hesitancy to use Elevidys and increase investor distrust since Sarepta did not disclose the latest fatality on a call earlier this week.
The company said on Wednesday it had halted development of several gene therapies for limb-girdle muscular dystrophy, a group of genetic disorders that primarily weaken the hip and shoulder muscles.
Sarepta had also said it planned to present mid-stage data for its gene therapy, SRP-9003, for the disorder later this year, which will be included in its marketing application to the U.S. Food and Drug Administration.
Corwin added the news of the third patient death could also lead to greater scrutiny over the safety of SRP-9003.
Sarepta plans to cut 500 jobs and add a serious warning on the label of Elevidys for the risk of acute liver injury and liver failure in DMD patients who can walk.

OpenAI releases open-weight reasoning models optimized for running on laptops
SAN FRANCISCO, Aug 5 (Reuters) - OpenAI said on Tuesday it has released two open-weight language models that excel in advanced reasoning and are optimized to run on laptops with performance levels similar to its smaller proprietary reasoning models. An open-weight language model's trained parameters or weights are publicly accessible, which can be used by developers to analyze and fine-tune the model for specific tasks without requiring original training data. "One of the things that is unique about open models is that people can run them locally. People can run them behind their own firewall, on their own infrastructure," OpenAI co-founder Greg Brockman said in a press briefing. Open-weight language models are different from open-source models, which provide access to the complete source code, training data and methodologies. The landscape of open-weight and open-source AI models has been highly contested this year. For a time, Meta's (META.O), opens new tab Llama models were considered the best, but that changed earlier this year when China's DeepSeek released a powerful and cost-effective reasoning model, while Meta struggled to deliver Llama 4. The two new OpenAI models are the first open models OpenAI has released since GPT-2, which was released in 2019. OpenAI's larger model, gpt-oss-120b, can run on a single GPU, and the second, gpt-oss-20b, is small enough to run directly on a personal computer, the company said. OpenAI said the models have similar performance to its proprietary reasoning models called o3-mini and o4-mini, and especially excel at coding, competition math and health-related queries. The models were trained on a text-only dataset which in addition to general knowledge, focused on science, math and coding knowledge. OpenAI did not release benchmarks comparing the open-weight models to competitors' models such as the DeepSeek-R1 model. Microsoft-backed OpenAI, currently valued at $300 billion, is currently raising up to $40 billion in a new funding round led by Softbank Group (9984.T), opens new tab.

US criticizes use of AI to personalize airline ticket prices, would investigate
Aug 5 (Reuters) - U.S. Transportation Secretary Sean Duffy said Tuesday the department has concerns about the use of AI to set personalized airline ticket prices and will investigate if anyone does so. Last week, Delta Air Lines (DAL.N), opens new tab told lawmakers it will not and has not used AI to set prices for individual consumers. "To try to individualize pricing on seats based on how much you make or don't make or who you are, I can guarantee you that we will investigate if anyone does that," Duffy said. "We would engage very strongly if any company tries to use AI to individually price their seating." Duffy noted Delta clarified that it would not use AI for pricing individual tickets, "and I'll take them at face value." Late last month, Democratic Senators Ruben Gallego, Mark Warner and Richard Blumenthal said they believed the Atlanta-based airline would use AI to set individual prices, which would "likely mean fare price increases up to each individual consumer's personal 'pain point.'" Delta previously said it plans to deploy AI-based revenue management technology across 20% of its domestic network by the end of 2025 in partnership with Fetcherr, an AI pricing company. Fetcherr on its website says its technology is "trusted by the world's leading airlines," and lists Delta, Westjet, Virgin Atlantic, Viva and Azul. American Airlines (AAL.O), opens new tab CEO Robert Isom said last month using AI to set ticket prices could hurt consumer trust. Democratic lawmakers Greg Casar and Rashida Tlaib have introduced legislation to bar companies from using AI to set prices or wages based on Americans' personal data and would specifically ban airlines raising individual prices after seeing a search for a family obituary. Delta said airlines have used dynamic pricing for more than three decades, in which pricing fluctuates based on a variety of factors like overall customer demand, fuel prices and competition, but not a specific consumer's personal information.

The tech company winning big from Trump's presidency
Alex Karp, the chief executive of Palantir Technologies, was in no mood to be humble as the US tech giant revealed its results on Monday. 'I have been cautioned to be a little modest about our bombastic numbers,' Karp said. Yet in a note to shareholders, he said the company's current growth rate was 'without precedent or comparison'. Palantir, which develops artificial intelligence (AI) and data mining technology, reported a 48pc jump in its quarterly revenues to a record $1bn (£753m). Dan Ives, a technology analyst, said Palantir had 'blown away' expectations. Growth has been delivered in part thanks to the company's close ties to Washington and the US defence establishment, with US government sales up 52pc. Since Donald Trump's election victory in November, Palantir's stock has risen by almost 300pc. 'This is the perfect time for Palantir,' Karp told investors on a call. Palantir and Karp, a one-time Democratic Party donor and supporter of Kamala Harris, are well-placed to benefit from the Trump White House's focus on defence, homeland security and securing its borders. Last week, the US army signed a deal with Palantir worth up to $10bn over the next decade. Its work with the US military includes developing AI-powered mobile command trucks and a high-tech targeting system called Maven, which can do the work of a regiment of soldiers with just 20 people. Founded in 2003 by Karp and Peter Thiel, the outspoken Republican donor, Palantir's tools can synthesise vast pools of data for analysis or business decision-making. Its early work included contracts with the CIA and other intelligence services. The business and its leaders have always been outspoken believers in America's role as the bulwark of Western civilisation. In a military context, for instance, Palantir can gather information from an army's databases, satellites and drones, then combine it with publicly available information to help commanders make tactical decisions. However, it is not just military and intelligence chiefs who covet Palantir's technology. Its services have also been hotly sought after by corporations and the public sector. It is also a major supplier to the NHS. One relationship that has been under intense recent scrutiny is Palantir's work with the US immigration and customs enforcement (Ice) agency. Its technology has been deployed on the US border and Palantir has worked with Ice since 2014, largely on tools to aid criminal investigations. A deal signed in 2022 to extend this work was worth $95m. Its border work most recently expanded with a $30m deal in April to build an 'ImmigrationOS'. This, according to a federal contract, will help track known criminals, identify people overstaying their visas, and track deportation data. 'Palantir is the only source that can provide the required capabilities and prototype of ImmigrationOS without causing unacceptable delays,' a US tender document says. The contract was single sourced, meaning it was not offered in a competitive process. The Trump White House has already claimed victory over immigration and illegal border crossings. In a post on X, the White House claimed to have achieved the 'first negative net migration for the first time in 50 years'. Trump has hailed a dramatic fall in illegal border crossings as evidence that his policies of tougher border security and mass deportations of immigrants, shackled in chains and handcuffs, are working. However, the president's uncompromising approach to the issue has led to criticism of Palantir by association. Its offices have been targeted by 'Purge Palantir' demonstrators, mirroring the earlier 'Tesla Takedown' protests against Elon Musk's car business. Former staff, meanwhile, signed an open letter claiming Palantir executives were enabling a 'dangerous expansions of executive power' through their work for Trump. The company has previously admitted employees have 'left over disagreements on our work, now and in the past, and we pride ourselves on a culture of fierce internal dialogue'. Karp has repeatedly dismissed criticism from the 'haters' (although in one rebuke, Palantir published an over 4,000 word response to an article in the New York Times that interrogated its US government deals). 'Palantir gets attacked just because we help make this country even better,' Karp told investors on Monday. 'The people who think we are wrong have to be a little jealous.' Palantir is not the only tech company benefiting from the second Trump presidency. The 'big beautiful bill' earmarked a total of $6bn for border security technology, including AI-powered surveillance towers. These are likely to be designed by Anduril, another US defence technology start-up backed by Thiel, Palantir's founder. In fact, according to news organisation The Intercept, Anduril is a shoo-in. The law states that the towers must be certified by the US border patrol to get the funding – and only Anduril's technology meets that requirement. The bill has also given Ice a budget larger than many global militaries, climbing from $8bn to almost $28bn. Palantir pointed out in its financial results that its commercial sales have also soared as businesses have sought to use tools originally designed for the world's security agencies. Its US business sales climbed 93pc. 'The growth rate of our business has accelerated radically, after years of investment on our part and derision by some,' Karp wrote in a letter to investors on Monday. 'The sceptics are admittedly fewer now, having been defanged and bent into a kind of submission. Yet we see no reason to pause, to relent, here.'
