The pharmaceutical industry is navigating a turbulent period as of May 2025, with significant policy, regulatory, and corporate developments reshaping its landscape. From a high-profile executive order to unexpected leadership changes, these events signal a transformative moment for the sector. Below, we explore the latest news, their implications, and what they mean for stakeholders.

Trump’s Drug Pricing Executive Order
On May 12, 2025, President Donald Trump signed an executive order introducing a “most favored nation” (MFN) policy to lower U.S. drug prices. This policy aims to align U.S. prices with those in other countries where medications are cheaper, addressing long-standing concerns about high drug costs (Fierce Pharma). The order has sparked both optimism and apprehension. Supporters argue it will make medications more accessible for consumers, potentially easing financial burdens. However, critics, including pharmaceutical companies, warn that reduced revenues could stifle innovation and limit the development of new treatments (CNBC).
Industry analysts, such as BMO’s Seigerman, suggest that while the order generates significant attention, its implementation may face logistical and legal hurdles, potentially limiting its immediate impact (Fierce Pharma). For now, pharmaceutical companies are closely monitoring the situation, as the policy could reshape pricing strategies and market dynamics.
FDA’s Decision on Fluoride Supplements
On May 13, 2025, the U.S. Food and Drug Administration (FDA) announced it is initiating a process to remove fluoride supplements for children from the market, citing concerns about their safety (Reuters). These supplements, typically prescribed as tablets, drops, or lozenges for children in areas without fluoridated water, have been used for decades to prevent dental cavities. The FDA, under the leadership of Health Secretary Robert F. Kennedy Jr., claims that ingested fluoride may disrupt healthy gut bacteria and could be linked to issues like decreased IQ, though the cited research remains inconclusive ).
This decision has stirred controversy, as it contradicts established dental practices endorsed by organizations like the American Dental Association. Dentists worry that removing these supplements could increase cavity rates, particularly in underserved communities (PBS News). Manufacturers of fluoride products face potential market losses, while public health officials grapple with balancing safety concerns and oral health needs.
GSK and iTeos Discontinue Lung Cancer Therapy
On May 13, 2025, GSK and iTeos Therapeutics announced the termination of their experimental lung cancer therapy, belrestotug, after it failed to demonstrate sufficient efficacy in two mid-stage clinical trials (Reuters). The therapy, designed to target the TIGIT receptor, was being tested in combination with GSK’s dostarlimab for non-small cell lung cancer. The decision to halt development reflects broader challenges in the oncology field, where TIGIT-targeting therapies have faced repeated setbacks, with similar drugs from Merck and Roche also failing trials (Bloomberg).
For GSK and iTeos, this discontinuation means redirecting resources to other pipeline candidates. iTeos, which reported a strong cash position of $624.3 million, remains optimistic about future clinical readouts (Investing.com). However, the news underscores the high risks and costs associated with drug development, particularly in competitive areas like cancer treatment.
UnitedHealth CEO Steps Down
In a surprising corporate shakeup, UnitedHealth Group’s CEO, Andrew Witty, resigned on May 13, 2025, citing personal reasons. Stephen Hemsley, the company’s chairman and former CEO from 2006 to 2017, has returned to the CEO role (Reuters). The announcement was accompanied by UnitedHealth suspending its 2025 earnings guidance due to surging medical costs, particularly in its Medicare Advantage business, leading to a nearly 18% drop in shares (NBC News).
Witty’s departure comes at a challenging time for UnitedHealth, which has faced issues like a cyberattack affecting 190 million people and the murder of its UnitedHealthcare CEO, Brian Thompson, in December 2024 (CNN Business). Hemsley, credited with building the Optum health services business, now faces the task of stabilizing the company amid these financial and reputational challenges (Bloomberg).
Broader Industry Context
Beyond these specific events, the pharmaceutical industry is grappling with broader trends. Reports indicate turmoil at the National Institutes of Health (NIH), which could affect research funding for drugmakers (PharmaVoice). Additionally, a proposed 20% cut to the FDA’s workforce may lead to delays in drug approvals, impacting biotechs and pharmaceutical companies (PharmaVoice). These challenges, combined with the tariff war prompting calls to reshore manufacturing, create a complex environment for the industry (PharmaVoice).
Other notable developments include Roche’s announcement of a $50 billion investment in the U.S. over the next five years, expected to create over 12,000 jobs (World Pharma News). Meanwhile, companies like Piramal Pharma and BioMarin are advancing new products and clinical trials, signaling continued innovation despite setbacks (PR Newswire).
