GS030 / GenSight - LARVOL DELTA

Bringing gene-independent strategies to the clinic: focus on Optogenetics (ARVO 2023) - P1/2 | "Initial results of the clinical trial NCT03326336 evaluating the safety and tolerability of the combination product “GS030-Drug Product and GS030-Medical Device (engineered goggles)” showed that the optogenetic therapy partially restored vision to a 58-year-old man who had been diagnosed with Retinitis Pigmentosa 14 years earlier and whose vision was limited to rudimentary light perception...As a mutation-independent therapeutic strategy, optogenetics carries a great potential for treatment of a broad spectrum of retinal dystrophies with photoreceptor degeneration. It complements other gene-independent approaches e.g. neuroprotection by Rod-derived Cone Viability Factor potentially applicable at earlier stages."

Current and Future Treatment of Retinitis Pigmentosa. (PubMed, Clin Ophthalmol) - "Amongst the 15 cell and gene therapies in late-stage development, 5 leading candidates have been selected to profile based on the development stage, drug target and geography: gene therapies AGN-151597, GS-030 and VMCO-1 and human stem cell therapies jCell and ReN-003. Gene therapies may be attractive as their fundamental goal is to restore vision; however, cell therapies will likely have a broader application and do not rely on genetic testing, which can delay treatment. Ensuring effective therapeutic options for RP patients across disease stages requires the continued diversification and advancement of the development pipeline, and sustained efforts to promote early patient identification and timely diagnosis."

PIONEER is the first clinical trial combining a gene therapy independent of underlying genetic defects and a light-stimulating medical device in the treatment of RP, and as such offers great promise in the treatment of inherited retinal diseases."

Organophosphate hydrolase interacts with ferric-enterobactin and promotes iron uptake in association with TonB dependent transport system. (PubMed, Biochem J) - "The E. coli GS030 cells having SfTonBDT system with OPH showed increased iron uptake. Such an increase was not seen in E. coli GS029, cells having SfTonBDT system generated either by omitting OPH or by including its variants, OPHD301A, OPHD301N suggesting a role for OPH in enhanced iron uptake."
