Treatment with indoleamine dioxygenase-1 (IDO1) inhibitors reduced both viremia and B cell transformation in animal models of post-transplant lymphoproliferative disorder (PTLD), while IDO1 up-regulation occurred in patients who would go on to develop PTLD. The findings, which were reported in the May 24, 2024, issue of Science by researchers from the University of Basel and the University Hospital Basel, point to new ways to predict, prevent and treat complications of Epstein-Barr virus (EBV) infection.
As South Korea’s Curocell Inc. looks to develop the country’s first homegrown CAR T-cell therapy, CEO Gunsoo Kim highlighted rising and falling trends in the global CAR T development space at Bio Korea 2024.
Zai Lab Ltd., of Shanghai and Cambridge, Mass., has been on a regulatory roll in China, gaining approval of Bristol Myers Squibb Co.’s Augtyro (repotrectinib) for lung cancer on May 12 and NMPA acceptance of subcutaneous Vyvgart‘s (efgartigimod alfa SC) supplemental BLA with priority review on May 14.
From glaucoma to Stargardt disease, age-related macular degeneration (AMD) to retinitis pigmentosa, or a corneal transplant to Bietti’s crystalline dystrophy, the 27th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) is working to bring some light to patients with age and congenital diseases that affect vision. From May 7-11, 2024, thousands of scientists are gathering in Baltimore to show their advances against the challenges of delivering genes and cells to the correct place, avoiding immunogenicity and improving diseases.
Despite what University of Pennsylvania (Penn) immunotherapy pioneer Carl June referred to as a “cold slap last November” – a launched investigation by the U.S. FDA into a possible link between CAR T-cell immunotherapies and secondary cancers – new unpublished studies by Penn and Stanford University highlight the rarity of such cases.
Boston-based South Korean biotech Genosco Inc. said on April 25 that it passed a technology review required for the special listing track on the tech-heavy Kosdaq market, as it readies an IPO on the Korea Exchange.
Samsung Bioepis Co. Ltd. and Celltrion Inc. are making headway in Europe and U.S. with respective follow-on biologic products, with Samsung Bioepis the latest to gain EMA approval for Pyzchiva, a Stelara (ustekinumab, Janssen Pharmaceuticals Inc.) biosimilar, on April 23.
The timing is ripe for a robust biosimilar market in China, given the rapid increase of novel biologics approved to treat cancer and inflammatory diseases in the country over the past decade and the looming patent cliffs for several established biologics. As of December, the NMPA had approved more than 20 biosimilars that were developed in China. Most of those referenced just two biologics – Roche AG’s cancer drug Avastin (bevacizumab) and Abbvie Inc.’s immunology drug Humira (adalimumab). In 2022, the oncology and immunology biosimilar market in China garnered sales of about $2 billion, according to Clarivate estimates. To reach their full potential in China though, biosimilars must win over prescribers and patients.
After reviewing data from its phase II trial of farnesoid X receptor agonist ASC-42 in primary biliary cholangitis, Ascletis Pharma Inc. said it was quitting development of the molecule in all indications.
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.
