AACR 2024: New concepts suggest new targets for metastatic disease

April 10, 2024
By Anette Breindl
Prior to this year’s Annual Meeting of the American Association for Cancer Research (AACR), it had been 14 years since metastasis had been the subject of a plenary session. So, the Tuesday session on “Evolution of the genome, microenvironment, and host through metastasis” had plenty of new insights to share.

AACR 2024: Getting older younger may be driving rise in early-onset cancers

April 8, 2024
By Anette Breindl
As with most common diseases of the developed world, aging is the major risk factor for developing cancer. Most of the half-dozen hallmarks of precancer that were published last week by investigators from Vanderbilt University and the Fred Hutchinson Cancer Research Center are also hallmarks of aging. Unfortunately, scientists reported at the American Association for Cancer Research’s (AACR) 2024 annual meeting this week that accelerated aging is increasing, and may be driving an increase in early-onset cancers.

Better drugs for neurodegeneration will take more research, better biomarkers

April 5, 2024
By Anette Breindl
At a recent meeting on “Research priorities for preventing and treating Alzheimer’s disease and related dementias” (ADRD), convened by the National Academies, one consensus priority on ADRD research was that there needs to be more of it at every stage. Several speakers presented stark numbers on the relative volume of research in cancer and neurodegeneration. Research output, measured in peer-reviewed papers, for dementia is estimated to be around 10,000 papers annually, compared to 150,000 for cancer, while AD clinical trials are also few and far between compared to cancer trials. This final installment of BioWorld’s series on Alzheimer’s explores some of the reasons for this discrepancy along with the latest advances and ongoing efforts to accelerate research and drug development in the field.

After the first approvals, where does amyloid go from here?

April 4, 2024
By Anette Breindl
After decades of trying and dozens of failed trials, amyloid targeting has paid off with the first disease-modifying agents reaching the market. But success does not mean slam dunk. Aduhelm (aducanumab, Biogen Inc.) was dogged by controversy throughout its brief tenure, and Biogen pulled the plug on it in early 2024. Leqembi (lecanemab, Biogen Inc.) has received full approval. In this second installment of a three-part series on Alzheimer’s, BioWorld looks at the nuanced view of amyloid’s role in the disease.

Aging, and aging well, gives clues for dementia drug discovery

April 3, 2024
By Anette Breindl
Ironically, the first person to be diagnosed with what is now Alzheimer’s disease was missing its major risk factor. When she first began showing symptoms of dementia in 1901, Auguste Deter was not particularly old. Despite Deter’s case, aging is the largest risk factor for developing Alzheimer’s, by a large margin. But “geroscience has not been translated into drugs for Alzheimer’s disease,” Howard Fillit, Alzheimer’s Drug Discovery Foundation co-founder and chief scientific officer, told BioWorld. “We’re just starting to see that cross-fertilization now.” This first article of a three-part BioWorld series on Alzheimer’s disease looks at how a group of researchers, as well as some startups, are trying to approach Alzheimer’s via an aging lens.

Australian researchers discover gene mutation that causes psoriasis

April 2, 2024
By Tamra Sami
Scientists from the Australian National University have discovered the gene mutation responsible for causing psoriasis, and the findings could lead to improved diagnosis and treatment for patients with psoriasis and psoriatic arthritis, a chronic inflammatory skin disease. “We were able to identify the gene that could be important in enabling this progression from a skin-only condition to a skin-and-joint condition,” lead study author Chelisa Cardinez told BioWorld.

AI-driven research identifies pulmonary fibrosis target and inhibitor

March 25, 2024
By Mar de Miguel
Deep learning algorithms have enabled the discovery of molecular structures of interest in biomedicine to design treatments against aggressive diseases such as idiopathic pulmonary fibrosis (IPF). Scientists at Insilico Medicine Inc. selected a target for IPF using artificial intelligence (AI), then designed an inhibitor to block it, and tested it in vitro, in vivo, and in clinical trials.

Eledon takes new ‘tac’ with tegoprubart in kidney transplant

March 22, 2024
By Randy Osborne
Eledon Pharmaceuticals Inc.’s tegoprubart, an investigational anti-CD40 ligand antibody, was used as part of the immunosuppressive regimen after the first-ever transplant of a kidney from a genetically modified pig to a human. The tegoprubart procedure was done March 16 at Massachusetts General Hospital on a 62-year-old man with end-stage renal disease.

Tau protein in Alzheimer's disease

What’s going on beyond amyloid-β in Alzheimer’s disease management

March 22, 2024
By Coia Dulsat
After many years of testing different monoclonal antibodies against amyloid-β protein, the results obtained are far from being outstanding, and the control of the progression and symptoms of Alzheimer’s disease (AD) remains elusive. At the recent AD/PD 2024 conference held in Lisbon, new non-anti-amyloidogenic strategies in the starting line against AD were discussed. Professor Einar Sigurdsson from New York University gave a presentation entitled, “Single domain antibodies for therapy and diagnosis of synucleinopathies and tauopathies.”
