Bluebird Bio Inc. has completed a rolling BLA filing of beta-thalassemia gene therapy beti-cel in the U.S., with analysts predicting that the Cambridge, Mass.-based biotech will have to shoot for a lower price tag after running into trouble with cost regulators in Europe.

DUBLIN – Bacteriophage, like other viruses, can be viewed as complex molecular machines with two essential functions: infection and replication. The first involves the efficient injection into the host cell of their genomic payload; the second involves hijacking the host’s nucleic acid replication machinery to generate the functional and structural proteins needed to give rise to progeny viruses.

China is making strides in cell and gene therapy, notably so with a 61% surge in the number of clinical trials in six years, a new report by Ernst & Young showed. While analysts noted the increasing innovation efforts and cross-border collaborations, concerns remain if quality will be compromised by speed.

The 2017 FDA approval of Luxturna (voretigene neparvovec-rzyl, Roche Holding AG) spurred a race to create the next gene therapy for the eye. The organ is very amenable to gene therapy given that it's a confined space with post-mitotic cells that has immune privilege and requires substantially smaller amounts of viral vector compared to systemic treatments.

Money is flowing into gene therapy as investors have started looking favorably on the risk-reward prospects of the space. "I believe the risk has really substantially decreased as regulatory path has become clearer. There are more projects with lower risk," said Sarah Bhagat, a partner at Sofinnova Investments.

Prevail Therapeutics Inc. won't be prevailing on its own. Eli Lilly and Co. is acquiring the gene therapy company for $880 million up front plus an earn-out of up to $160 million if Lilly can gain regulatory approval for at least one of Prevail's drugs.
