The professor in residence of pediatrics at University of California San Francisco discussed his experiences investigating Lyfgenia in clinical trials.
“It's spectacular when it works, and it's disappointing when it takes a longer period of time to generate a benefit. And that's kind of the way medicine is, a lot of the time once the glow of success wears off a bit, then reality sinks in and you realize that this is a great treatment, but it's not going to work for everybody.”
The field of sickle cell disease (SCD) is nearing 3 months since the landmark FDA approvals of bluebird bio’s lovotibeglogene autotemcel (lovo-cel), marketed as Lyfgenia and Vertex and CRISPR Pharmaceuticals' exagamglogene autotemcel (exa-cel; Casgevy) in December, the first approved gene therapies for treating sickle cell disease (SCD).
Lovo-cel, which, along with exa-cel, is approved for patients aged 12 years and older with SCD, consists of autologous CD34+ hematopoietic stem cells collected by plerixafor mobilization and apheresis, transduced with BB305 lentiviral vector (LVV) encoding the human beta-A-T87Q globin gene.
CGTLive® spoke with Mark Walters, MD, professor in residence, pediatrics, Sickle Cell Center of Excellence, University of California San Francisco, to learn more about his experiences with and lessons learned while investigating lovo-cel. Walters served as an investigator on the phase 1/2 HGB-205 (NCT02151526) and HGB-206 (NCT02140554) clinical trials evaluating lovo-cel. He also shared some early research with SCD in vivo gene editing therapy that is excited to see more of.
Bendamustine Is an Effective Alternative to Fludarabine-Based Lymphodepletion in LBCL
December 7th 2024In the wake of fludarabine shortages, lemphodepletion with bendamustine was found to be an effective alternative compared for patients with large B-cell lymphoma being treated with a CD19-directed CAR T-cell therapy.
