Small molecule drugs and monoclonal antibodies often fall short at addressing severe inflammatory and immune‑mediated diseases. Mesoblast has spent more than 15 years industrializing mesenchymal stromal cell therapies to treat these conditions. In late 2024, it won U.S. Food and Drug Administration approval for Ryoncil, the first mesenchymal stromal cell therapy approved in the United States. Ryoncil is approved to treat steroid‑refractory acute graft‑versus‑host disease in pediatric patients 2 months of age and older. Mesoblast founder and CEO Silviu Itescu discusses how this class of therapy can help dampen cytokine‑driven hyperinflammation, how the company is extending its platform into other high‑burden conditions, and what distinguishes its second‑generation cell therapy now in development from its first.

Most existing therapies for multiple sclerosis do a good job of reducing relapses and inflammatory activity, but they largely fail to stop the slow neurodegeneration that drives long-term disability, especially in progressive forms of the disease. Immunic Therapeutics is trying to reshape the treatment landscape for multiple sclerosis with its experimental once-daily oral therapy, designed not only to curb inflammation and relapses but also to tackle the neurodegeneration that silently drives disability progression in both relapsing and progressive forms of MS. Daniel Vitt, CEO of Immunic, discusses how the company’s experimental MS therapy works, how it may protect neurons from cell death, and the potential for its dual mechanism of action to change the treatment landscape.

The treatment of inflammatory bowel disease currently relies on immunosuppressive therapies that often lose effectiveness, carry infection risks, and drive high treatment cycling. Abivax is betting that fine-tuning, rather than suppressing, the immune system can reshape the treatment paradigm in IBD. Marc de Garidel, CEO of Abivax, discusses how a once-failed HIV candidate evolved into a late‑stage oral IBD therapy that may deliver durable remission, how it acts upstream of key inflammatory pathways, and its potential in a crowded but still underserved IBD market.

Many people with the genetic condition Lynch syndrome live with the near‑certainty that they will one day develop cancer and have few options beyond constant screening and, in some cases, preventive surgery. Nouscom is trying to change that by training the immune system to spot and destroy cancer cells before tumors ever form. We spoke to Marina Udier, CEO of Nouscom, about the company’s experimental cancer vaccines, how they work, and the broader potential for the company’s off‑the‑shelf cancer therapies.

Alzheimer’s disease drug development has long focused on slowing memory loss, but for many families, the tipping point that makes home care impossible is not cognition—it is psychosis. Hallucinations and delusions in Alzheimer’s are a distinct, prevalent, and under-recognized target for therapy. We spoke to Elizabeth Thompson, executive vice president and head of R&D at Acadia Pharmaceuticals, about the biology behind psychosis in dementia, the company’s experimental therapy to treat the condition in people with Alzheimer’s disease, and the forces reshaping the drug development landscape to enable the development of such treatments.
