By transplanting a pig kidney into a brain-dead person, researchers have been able to conduct the first long-term study of the physiological processes occurring in both the transplant recipient and the pig organ for 61 days. The findings were published in the Nov. 14, 2025, issue of Nature in two papers – one focusing on physiological and immunological measurements, the other on multiomics.

Fifteen years since the first patient was treated, and after being ditched by two companies, the EMA is recommending approval of Waskyra (etuvetidigene autotemcel), the first gene therapy for treating Wiskott-Aldrich syndrome.

South Korean researchers led by Lee In-suk of Yonsei University have reported the most complete oral microbiome catalog to date, with more than 72,000 genomes. Detailed in Cell Host & Microbe on Nov. 12, 2025, the database is expected to serve as a universal platform for academia and enable “precision microbiome medicine” for the industry, Lee told BioWorld.

In Alzheimer’s disease, microglia act as a double-edged sword. They can either protect the brain or worsen the damage, depending on their activation state. Inflammatory activation harms healthy neurons. However, a study reveals that a special type of microglia expressing specific receptors and behaving like T cells may help mitigate this neurodegenerative condition.

A primary endpoint failure but with outstanding estimated glomerular filtration rates and impressive safety data in the phase II trial called Bestow are adding up to plans for later-stage work with Eledon Pharmaceuticals Inc.’s tegoprubart (tego) for preventing rejection in de novo kidney transplant.

Takeda Pharmaceutical Co. Ltd.’s anti-CD38 antibody, mezagitamab (TAK-079), sustained kidney function up to 18 months after treatment ended in patients with primary immunoglobulin A (IgA) nephropathy, showing early signs of disease modification in a phase Ib study presented at the American Society of Nephrology’s Kidney Week 2025 in Houston.

San Francisco Bay Area researchers from UC Berkeley, UC San Francisco and Stanford University have combined their technologies to create Azalea Therapeutics Inc., a company focused on editing cells in vivo.

Celltrion Inc. scored a hat-trick of deals to license new antibody candidates, including a $744 million deal with Kaigene Inc. Nov. 3, and a near $500 million deal with Mustbio Co. Ltd. Oct. 31.

The U.S. FDA once again has a leadership gap at the top of its drug center, which already has been ravaged this year by massive terminations, resignations and retirements of senior leaders. George Tidmarsh, a biopharma industry veteran who’s helmed CDER for a little more than three months, resigned effective immediately Nov. 2 after being placed on administrative leave two days earlier amid a Department of Health and Human Services probe.

Boehringer Ingelheim GmbH has licensed an unnamed small-molecule preclinical candidate from Kyowa Kirin Co. Ltd. in the autoimmune disease space in a deal worth up to €640 million (US$739 million).
