Allogeneic CAR T-cell therapy offers several advantages over an individualized autologous CAR T approach, thanks to the use of readily available, higher quality and quantity of starting donor T cells and the potential to generate multiple doses from a single manufacturing process.
For 75 years, the standard tools for autoimmune disease have consisted of steroids, cytotoxics and broad biologics that tamp down the entire immune system. They can help, but they are rarely curative. “They’re blunt instruments,” Regcell Inc. CEO Mike McCullar told BioWorld. “They can’t distinguish good immune cells and bad immune cells,” which is why many carry black-box warnings and must be taken for years, sometimes for life.
In a recent publication in iScience, researchers from Peking University First Hospital investigated the therapeutic potential of SLC7A11 CAR T therapy for solid tumors, particularly colorectal and pancreatic cancers.
Durable reprogramming of human T cells may now be possible thanks to a new technique based on the CRISPRoff and CRISPRon methodology. Researchers from the Arc Institute, Gladstone Institutes, and the University of California San Francisco (UCSF) have stably silenced or activated genes in this type of immune cell without cutting or altering its DNA, making T cells more resistant, active, and effective against tumors.
Tr1x Inc. has obtained IND clearance from the FDA for TRX-319, paving the way for initiation of a phase I/IIa study in progressive multiple sclerosis (MS) early next year. TRX-319 is designed to combine targeted B-cell control with active anti-inflammatory signaling and T-cell regulation, with the goal of restoring immune balance.
Tessera Therapeutics Inc. has been awarded up to $41.3 million from the Advanced Research Projects Agency for Health (ARPA-H) as part of its EMBODY (Engineering of immune cells inside the body) program to support the development of Tessera’s in vivo CAR T therapy efforts.
The transition from complex and costly ex vivo strategies to platforms that enable direct cellular intervention within the body, known as in vivo therapies, is marking a paradigm change in the field of gene and cell therapies by simplifying manufacturing, improving tissue targeting and expanding clinical access to treatments.
As the many challenges facing cell therapies are being addressed, the CAR T field continues to evolve beyond its original design of T cells engineered to target hematological malignancies. During the 32nd Annual Congress of the European Society of Gene and Cell Therapy (ESGCT), held in Seville Oct. 7-10, several studies showed how this technology is being redefined as programmable and adaptable immune cells with expanded functional versatility.
