Gene editing strategies, from epigenetic engineering to cell reprogramming and genetic vaccines, are accelerating the development of new therapies that awaken the immune system to treat cancer, as presented last month in Rome at the 31st Annual Congress of the European Society of Gene and Cell Therapy (ESGCT). Some of these advances are taking advantage of the conditions of the tumor microenvironment, where cancer cells coexist with immune cells, microorganisms and blood vessels.

Poseida Therapeutics Inc. has announced the nomination of a new development candidate under its collaboration with F. Hoffmann-La Roche Ltd., triggering a milestone payment from Roche to Poseida.

Immpact Bio USA Inc. has obtained IND clearance from the FDA for IMPT-514, a CD19/CD20 bispecific chimeric antigen receptor (CAR) T-cell therapy for the treatment of adult patients with multiple sclerosis (MS). A phase I trial will focus on patients who have suboptimal disease control despite prior treatment with high efficacy disease-modifying therapies in all forms of MS.

Precision Biosciences Inc. has announced that its experimental allogeneic T cell therapy azercabtagene zapreleucel (azer-cel) for the treatment of multiple sclerosis (MS) has received IND clearance from the FDA.

CSPC Pharmaceutical Group Ltd. has received clearance from China’s National Medical Products Administration (NMPA) to conduct clinical trials in China with its BCMA-targeting CAR T cell SYS-6020 for systemic lupus erythematosus (lupus) in China.

Tr1x Inc. has announced that the FDA has cleared its IND application for its engineered Tr1 Treg cell therapy TRX-103 for treatment-refractory Crohn’s disease.

Shinobi Therapeutics Inc. has been awarded non-dilutive grant funding of up to $59 million by the Japanese Agency for Medical Research and Development (AMED).

Investigators at McMaster University have developed a CAR T cell that targeted roundabout guidance receptor 1 (ROBO1).

To be successful, CAR T-cells need a balance between being effective and overkill. Researchers from the University of Pennsylvania and Vittoria Biotherapeutics Inc. have eliminated the CD5 signaling pathway of their CAR Ts to prevent the immunosuppressive brake effect. In return, this improved their proliferation and antitumor activity in T cell lymphomas.
