AACR Meeting News: Synlogic Presents Encouraging Data on Immunotherapy Drug

On the first day of the American Association for Cancer Research (AACR) annual meeting, the synthetic biology company Synlogic presented data from a Phase I trial of their immunotherapy drug, SYNB1891. The drug, which consists of engineered bacteria that are injected intratumorally, is being developed for the treatment of solid tumors and lymphoma. The data suggest that the drug is safe, well-tolerated, and activates the STING pathway in patients.

Scientists Develop CRISPRoff for Controlling Gene Expression through Heritable Epigenetic Memory

Scientists led by a team at the Whitehead Institute developed a gene editing technology, CRISPRoff, that utilizes a programmable, epigenetic memory writer protein to silence gene expression, without altering the underlying DNA sequence. Studies showed this epigenetic memory is heritable for hundreds of cell divisions, is fully reversible, and can also be used to silence non-coding genome elements such as enhancers.

Bacteriophage to the Future: Insights from the 3rd Bacteriophage Therapy Summit

Challenges facing phage therapy range from a developing regulatory landscape and the design of clinical trials to the up-scaling of manufacturing processes. With lots of good science, practicality considerations, and clinical strategies along with funding concerns, the 3rd Bacteriophage Therapy Summit provided a great opportunity to discuss the current state of phage therapy and the pathway to regulatory approval.

Mutation-Specific RNA Therapy Can Improve Vision with Lasting Effects

A Penn Medicine patient with a genetic form of childhood blindness gained vision, which lasted more than a year, after receiving a single injection of an experimental RNA therapy into the eye. Results from the Scheie Eye Institute in the Perelman School of Medicine at the University of Pennsylvania trial showed that the treatment led to marked changes at the fovea, the most important locus of human central vision. The treatment was designed for patients diagnosed with Leber congenital amaurosis (LCA), an eye disorder that primarily affects the retina, who have a CEP290 mutation.

Addressing the Top Five Challenges to AAV-Based Gene Therapy with ddPCR

Producing a safe and effective AAV-based treatment is not easy: The steps taken to extract and purify AAV vectors are not perfect. And ultimately, an imperfect product can put patients at risk. Many of the quality issues associated with AAV development stem from the fact that AAVs are produced in live cells in cell culture. GEN dives into the top five bioprocessing challenges that AAV developers face.
