Bird flu may be spreading in cows via milking and herd transport
The bird flu virus spreading through dairy cattle in the United States may be expanding its reach via milking equipment, the people doing the milking, or both U.S. Department of Agriculture (USDA) representatives reported today at an international, virtual meeting held to update the situation. The avian virus may not be spreading directly from cows breathing on cows, as some researchers have speculated, according to USDA scientists who took part in the meeting organized jointly by the World Organisation for Animal Health and the U.N.’s Food and Agricultural Organization. “We haven't seen any true indication that ...

WHO Documents Rising Resistance to First-Line HIV Drug
Currently, the World Health Organization (WHO) recommends using dolutegravir, an integrase strand transfer inhibitor approved by the US Food and Drug Administration in 2013, as a first- and second-line drug for treating people with HIV. But resistance to the treatment is on the rise. About 4% to as many as about 20% of people in 4 countries reporting data —Malawi, Mozambique, Uganda, and Ukraine—who had not achieved viral suppression exhibited resistance while taking the drug as part of their antiretroviral therapy, a recent report by the WHO found.

Current issues in dose-finding designs: A response to the US Food and Drug Adminstrations's oncology center of excellence project optimus
Clin Trials. 2024 Apr 3:17407745241234652. doi: 10.1177/17407745241234652. Online ahead of print.ABSTRACTWith the advent of targeted agents and immunological therapies, the medical research community has become increasingly aware that conventional methods for determining the best dose or schedule of a new agent are inadequate. It has been well established that conventional phase I designs cannot reliably identify safe and effective doses. This problem applies, generally, for cytotoxic agents, radiation therapy, targeted agents, and immunotherapies. To address this, the US Food and Drug Administration's Oncology Center of E...

Scoring PD-L1 Expression in Urothelial Carcinoma: An International Multi-Institutional Study on Comparison of Manual and Artificial Intelligence Measurement Model (AIM-PD-L1) Pathology Assessments
AbstractAssessing programmed death ligand 1 (PD-L1) expression on tumor cells (TCs) using Food and Drug Administration-approved, validated immunoassays can guide the use of immune checkpoint inhibitor (ICI) therapy in cancer treatment. However, substantial interobserver variability has been reported using these immunoassays. Artificial intelligence (AI) has the potential to accurately measure biomarker expression in tissue samples, but its reliability and comparability to standard manual scoring remain to be evaluated. This multinational study sought to compare the %TC scoring of PD-L1 expression in advanced urothelial car...

Programmatic considerations and evidence gaps for chikungunya vaccine introduction in countries at risk of chikungunya outbreaks: Stakeholder analysis
by Megan Auzenbergs, Clara Maure, Hyolim Kang, Andrew Clark, Oliver Brady, Sushant Sahastrabuddhe, Kaja Abbas Chikungunya can have longstanding effects on health and quality of life. Alongside the recent approval of the world ’s first chikungunya vaccine by the US Food and Drug Administration in November 2023 and with new chikungunya vaccines in the pipeline, it is important to understand the perspectives of stakeholders before vaccine rollout. Our study aim is to identify key programmatic considerations and gaps in Ev idence-to-Recommendation criteria for chikungunya vaccine introduction. We used purposive and snowball...

Profiling lecanemab as a treatment option for Alzheimer's disease
Expert Rev Neurother. 2024 Apr 3:1-9. doi: 10.1080/14737175.2024.2333970. Online ahead of print.ABSTRACTINTRODUCTION: In July 2023, the U.S. Food and Drug Administration (FDA) granted full approval to lecanemab for the treatment of mild cognitive impairment (MCI) due to Alzheimer's disease (AD) and mild AD dementia. Considering the limited treatment options for AD, the approval of lecanemab offers hope and opens the door for other disease-modifying therapies in the pipeline.AREAS COVERED: In this review, the authors summarize the FDA treatment guidelines, other anti-amyloid agents, and drug information relevant to prescrib...
