Three scientists whose groundbreaking work redefined the future of cystic fibrosis (CF) care have been awarded one of the world’s most prestigious honors in medicine: the Lasker-DeBakey Clinical Medical Research Award. Often referred to as the “American Nobel,” the award recognizes contributions that radically improve human health. This year, it went to Dr. Michael Welsh of the University of Iowa, Paul Negulescu of Vertex Pharmaceuticals, and Jesús (Tito) González, now of Integro Theranostics.

Together, their decades of research led to the creation of Trikafta, a therapy that has extended the lifespan of cystic fibrosis patients by decades and fundamentally reshaped what it means to live with the disease.

When cystic fibrosis was first described in the 1930s, it was considered a fatal childhood condition. Patients rarely survived past elementary school. Even as late as the 2010s, before Trikafta’s approval in 2019, half of patients with CF died before the age of 40.

Today, the outlook is dramatically different. Children born with CF between 2020 and 2024 who have access to Trikafta now face a median survival age of 65 years — nearly indistinguishable from the general population.

As Dr. Eric Sorscher of Emory University explained in The New England Journal of Medicine, “Available projections suggest that health and longevity may increase further as modulators begin to be administered at younger ages.”

This shift marks one of the most profound turnarounds in modern medicine.

The Role of the CFTR Gene

Cystic fibrosis is caused by mutations in a single gene: CFTR (cystic fibrosis transmembrane conductance regulator). The gene is critical for regulating the movement of ions across cell membranes, which in turn ensures proper water balance in tissues.

In healthy cells, CFTR forms channels that allow ions to flow freely. But in CF, the mutated gene produces faulty channels. The result is thick, sticky mucus that clogs the lungs and digestive system, fuels recurrent infections, and damages organs over time.

Dr. Michael Welsh, a pulmonologist and molecular biologist, helped illuminate the exact ways the most common CF mutation, delta-F508, disrupts cell function. He discovered two problems: the defective protein often gets “trapped” inside cells before reaching the surface, and even when it does reach the surface, it underperforms.

In a pivotal experiment, Welsh showed that simply lowering the temperature of cells allowed the trapped protein to move correctly. “That meant it was not totally broken,” he later recalled — a crucial realization that opened the door to correcting the defect.

Meanwhile, as a postdoctoral researcher in Nobel laureate Roger Tsien’s lab, Jesús (Tito) González developed a real-time system to track ion movement across membranes. Initially designed to study neurons, this tool proved invaluable for testing whether new drugs could restore CFTR function.

Negulescu and the Push to Find a Therapy

At Vertex Pharmaceuticals, Paul Negulescu helped drive the systematic search for compounds that could repair CFTR defects. Guided by Welsh’s molecular insights and González’s imaging system, the team screened thousands of molecules. The result was Trikafta, a triple-drug therapy that addressed the underlying cause of CF for most patients.

'Trikafta' Of Game-Changer in CF Treatment

Approved by the FDA in 2019, Trikafta combines three drugs — elexacaftor, tezacaftor, and ivacaftor — that work synergistically to help defective CFTR proteins fold correctly, reach the cell surface, and function effectively. The impact has been extraordinary. Since its introduction:

• Hospitalizations for lung infections have plummeted.
• The need for lung transplants has declined.
• Patients report stronger lung function, weight gain, and dramatically improved quality of life.
• For many families, the treatment has meant that milestones once unimaginable — graduating college, starting families, living into retirement — are now within reach.

Recognition at the “American Nobels”

The Lasker Awards, founded in 1945, celebrate biomedical achievements that shape the future of health. They are considered one of the highest honors in science, often predicting future Nobel Prizes.

The recognition of Welsh, González, and Negulescu underscores the profound impact of their work. The $250,000 prize, while symbolic compared to the billions Trikafta has generated, highlights the ethical and humanitarian dimension of their achievement: turning a once uniformly fatal disease into a chronic, manageable condition.

What CF Treatment Means for Medicine?

The CF breakthrough is not just about one disease. It represents a paradigm shift in genetic medicine. By targeting the root molecular defect rather than simply managing symptoms, Trikafta has become a model for other genetic conditions, from sickle cell disease to rare metabolic disorders.

It also illustrates the power of partnerships between academic researchers, biotech innovators, and patient foundations. The Cystic Fibrosis Foundation’s early investments in research were critical to advancing the work that ultimately led to Trikafta’s approval.

While Trikafta has transformed care in wealthy countries, challenges remain. The therapy is expensive — with an annual price tag of over $300,000 in the U.S. — putting it out of reach for many patients globally.

Furthermore, a subset of CF patients with rare genetic mutations still do not benefit from the drug, leaving an urgent need for alternative therapies. And as with all long-term treatments, researchers must continue monitoring for side effects and resistance.

Roughly 100,000 people worldwide live with cystic fibrosis. For decades, their lives were defined by daily medical regimens, frequent hospitalizations, and shortened lifespans. Today, thanks to the pioneering work of Welsh, González, and Negulescu, those same patients are looking toward futures filled with possibility.

China has become the world’s first country to approve a monoclonal antibody drug called Libevitug to treat hepatitis D — a severe, chronic liver disease.

The drug, which was rolled out at a Beijing hospital recently, was granted conditional approval by China's National Medical Products Administration in January 2026 following priority review, Science and Technology Daily reported.

Libevitug is a monoclonal antibody developed by a team from Tsinghua University and the Beijing-based biopharmaceutical company Huahui Health.

It works by blocking hepatitis B and D viruses from entering liver cells.

Clinical trials on Libevitug demonstrated significant efficacy in virological response and normalization of liver function, with particularly notable benefits for patients with cirrhosis.

What Is Hepatitis D? What Are The Key Symptoms?

Hepatitis D, or HDV, is different from the others—it can't infect the liver by itself. It only exists in those already infected with hepatitis B, employing the outer shell of the HBV virus to replicate.

When HBV and HDV infect the liver concurrently (a co-infection) or if HDV is contracted later on superimposition of pre-existing HBV (a superinfection), the immune system is twice assaulted. The liver has to cope with more intense inflammation, resulting in more rapid fibrosis progression and a much increased risk of cirrhosis and hepatocellular carcinoma.

In individuals with co-infection, liver injury is more severe, and complications arise years sooner than in HBV mono-infection. There are no specific therapies for HDV currently, and its management relies mostly on the control of hepatitis B.

It is also possible to prevent HBV infection and thereby hepatitis D by vaccination. Antiviral therapy and close follow-up can likewise decrease the chances of serious HDV complications in those already infected with HBV.

Simultaneous infection with HBV and HDV can lead to mild-to-severe hepatitis, with signs and symptoms typically appearing 3–7 weeks after initial infection and include:

• fever,
• fatigue,
• loss of appetite,
• nausea,
• vomiting,
• dark urine,
• pale-colored stools,
• jaundice (yellow eyes)
• fulminant hepatitis.

How Does Libevitug Work?

Of the over 254 million chronic hepatitis B carriers worldwide, approximately 5 percent are co-infected with the hepatitis D virus, and patients with co-infection have long lacked effective targeted therapies.

Clinical trials for the drug began in 2018, with an international multi-center study launched in 2023 among patients with chronic co-infection.

The drug previously received "Breakthrough Therapy Designation" from both the Center for Drug Evaluation (CDE) of the China NMPA and the US Food and Drug Administration (FDA).

"Libevitug demonstrates outstanding clinical efficacy and significantly improves liver stiffness, with particularly remarkable efficacy in patients with HBV/HDV-related cirrhosis," stated Professor Niu Junqi, principal investigator of the Libevitug trial from the First Hospital of Jilin University.

"This drug aligns with the core objectives of China's Action Plan for the Prevention and Control of Viral Hepatitis (2025–2030), which aims to improve diagnosis and treatment rates for viral hepatitis and reduce the incidence of liver cancer and mortality," Junqi added.

Junqi noted that Libevitug is expected to effectively lower the risk of disease progression to advanced severe diseases such as liver cancer, drive the diagnosis and treatment of HDV in China, as well as advance the goal of eliminating viral hepatitis as a public health problem by 2030.

Amid the growing burden of Non-Communicable Diseases (NCDs), India’s Union Ayush Ministry has launched yoga protocols that will target vulnerable groups with diabetes, high blood pressure, and asthma.

The “Yoga Protocol for Non-Communicable Diseases (NCDs) and Target Groups” is a significant push towards reshaping the country’s healthcare narrative from treatment to prevention, PTI reported.

NCDs such as diabetes, hypertension, cardiovascular ailments, chronic respiratory conditions, and mental health disorders are increasing significantly in the country. These also account for about 60 percent of all deaths in the country, signaling a clear need to focus on preventing the lifestyle-driven illnesses.

Prataprao Jadhav, Union Minister of State (Independent Charge) for Ayush, noted that prevention of these conditions is important for the better health of the nation, and yoga is India’s answer to the rising burden of lifestyle diseases.

“Through these evidence-based protocols, we are empowering every citizen to take charge of their own health and well-being in a simple, accessible, and sustainable manner. By integrating yoga into daily life, we aim to shift the focus from illness to wellness, reducing long-term healthcare pressures,” he said.

“This initiative reflects our commitment to building a healthier nation through holistic, preventive, and people-centric approaches rooted in India’s rich traditional knowledge,” the minister added.

What Are The Protocols?

It is part of the Yoga Mahotsav 2026, launched earlier this month by Union Ayush Minister Prataprao Jadhav, developed by the World Health Organization (WHO).

The protocols are designed as structured, evidence-based modules that integrate Yogic practices into daily life in a simple, accessible, and scalable manner.

The initiative has specific yoga interventions curated for major health conditions such as:

• diabetes — improving metabolic balance and glycemic control;
• hypertension — calming the nervous system and regulating blood pressure;
• bronchial asthma — strengthening respiratory capacity and improving lung function
• emotional well-being — breathing and meditation aimed at reducing stress, anxiety, and depression.

Further, it includes

• playful yoga modules for young children
• mental health-focused routines for adolescents,
• mobility-enhancing practices for the elderly
• specialized guidelines for women and pregnant mothers.

Yoga 365

The Ministry of Ayush has also launched Yoga 365 — a nationwide campaign to make yoga an integral part of citizens' daily lives — that goes beyond the International Day of Yoga (IDY), marked annually on June 21 worldwide.

According to the National Sample Survey (NSS), awareness of traditional systems like yoga stands at 95 percent in rural India and 96 percent in urban India.

The NSS also found that in around 1.1 crore households in rural India and around 1.4 crore households in urban India, at least one household member regularly practices yoga.

The Yoga 365 campaign aims to

• mobilize communities through mission-mode outreach,
• promote behavior change,
• integrate yoga into diverse spaces—from schools and offices to neighborhood groups and digital platforms.

The Morarji Desai National Institute of Yoga, under the Ministry of Ayush, has also signed a Memorandum of Understanding with the wellness platform Habuild to offer free daily online yoga sessions.

The COVID-19 BA.3.2 strain, nicknamed Cicada Variant, is spreading rapidly in the US, raising the possibility of becoming the dominant strain in the country, according to experts.

The US Centers for Disease Control and Prevention (CDC), in its latest report, has raised concerns about BA.3.2 — a highly mutated variant of COVID.

BA.3.2 has already been reported in at least 23 countries, including 25 states in America, as per the report. It has also been detected in 132 wastewater samples from Massachusetts.

The 25 states include California, Connecticut, Florida, Hawaii, Idaho, Illinois, Louisiana, Maine, Michigan, Maryland, Massachusetts, Missouri, New Hampshire, New Jersey, Nevada, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Texas, Utah, Vermont, Virginia, and Wyoming.

"Cicada can become the dominant strain in the US,” Dr. Robert H. Hopkins Jr., medical director of the National Foundation for Infectious Diseases, told USA TODAY.

While it is not certain, it can also "drive a US summer surge.”

The CDC warned that a new variant "with substantial capacity to evade immunity from previous infections or vaccines could be associated with seasonal increases in COVID-19 activity.”

In the US, COVID-19 is still linked to roughly 300 to 500 deaths per week, according to recent data based on provisional estimates from the CDC.

Brandon Dionne, an associate clinical professor of pharmacy and health systems sciences at Northeastern University, stated that the virus may evolve and increase the possibility of more severe disease.

“It’s something we definitely want to monitor,” Dionne said. “It could, over time, become the dominant strain in the US, but it’s not yet there," he said.

What Is The Cicada COVID Variant?

Cicada was first identified in a respiratory sample in South Africa in November 2024.

It is a descendant of the Omicron BA.3 lineage, and is genetically distinct from the previously circulating JN.1 lineages (including LP.8.1 and XFG).

BA.3.2 comprises two major branches, BA.3.2.1 and BA.3.2.2. BA.3.2.2 also has substitutions like: K356T, A575S, R681H, and R1162P.

The World Health Organization (WHO) has designated BA.3.2 as a Variant Under Monitoring (VUM). It means the variant may not be that dangerous yet, but it may have concerning mutations.

The CDC’s latest Morbidity and Mortality Weekly Report explains that Cicada has “70 to 75 substitutions and deletions in the gene sequence of its spike protein”.

Will Current COVID Vaccines Work?

The variant is particularly concerning as it provides no immune protection to people with previous infection or even vaccination.

“The number of mutations from JN.1 viruses makes it less likely that the current vaccines will be highly effective against Cicada, but we need more data to better answer this question,” Dr. Hopkins Jr. said.

However, according to the WHO, current COVID vaccines are expected to continue protecting against severe disease. Moreover, the WHO said BA.3.2 doesn’t seem to be making people sicker so far and hasn’t resulted in increased hospitalizations and deaths.

Common symptoms of Cicada variant include:

• Cough
• Fever or chills
• Sore throat
• Congestion
• Shortness of breath
• Loss of smell or taste
• Fatigue
• Headache.
