The U.S. FDA has granted Precision Biosciences Inc.’s PBGENE-DMD orphan drug designation for the treatment of Duchenne muscular dystrophy (DMD). PBGENE-DMD uses two complementary Arcus nucleases delivered via a one-time administration in a single AAV to excise exons 45-55 of the dystrophin gene in order to restore near full-length dystrophin protein within the body to improve functional outcomes.

Precision Biosciences Inc. has submitted its first clinical trial applications (CTAs) to initiate a phase I study evaluating PBGENE-HBV, an in vivo gene editing program designed to potentially cure chronic hepatitis B virus (HBV).

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.

Precision Biosciences Inc. has received pre-IND regulatory feedback from the FDA and ex-U.S. agencies providing alignment and clarity on Precision's final IND/CTA-enabling preclinical plans and clinical strategy for PBGENE-HBV.

Although there are different methods of nuclear gene editing, there are still no effective treatments against mitochondrial disorders due to genetic alterations. Now, a group of researchers at Precision Biosciences Inc. and the University of Miami (UM) has developed a genetic edition platform that targets mitochondrial DNA (mtDNA) to delete its mutations.

“The ARCUS technology that we use is based on an enzyme found in nature called I-CreI. It is an enzyme that recognizes a 22 base pair DNA sequence within a species of green algae. And when it finds that DNA sequence, it will generate double-strand breaks,” first author Wendy Shoop, a scientist at Precision Biosciences, told BioWorld.

Precision Biosciences Inc. uses its proprietary Arcus platform to develop in vivo gene editing therapies and has outlined new data from its wholly owned and partnered pipeline.

Immuno-oncology company Imugene Ltd. has acquired a worldwide exclusive license to Precision Biosciences Inc.’s allogeneic CD19 CAR T-cell therapy program in a deal worth more than $227 million. The off-the-shelf CD19 CAR T-cell therapy, azercabtagene zapreleucel (azer-cel), could potentially be the first allogeneic CAR T to be approved, Imugene CEO Leslie Chong told BioWorld.
