Y-mAbs Announces Development Update on Cancer Vaccine Program

Y-mAbs Therapeutics (NASDAQ:YMAB) has announced an update on its cancer vaccine program, the GD2-GD3 Vaccine.

As quoted in the press release:

At the Advances in Neuroblastoma Research (ANR) conference in San Francisco in May 2018, Phase 2 data utilizing GD2-GD3 Vaccine for Stage 4 high-risk neuroblastoma was presented. A total of 84 pediatric patients received the GD2-GD3 Vaccine, all of whom had prior relapses and finally regained second or later remissions before vaccine treatment. An interim analysis shows a progression free survival (PFS) of 51% and overall survival (OS) of 90% at 2 years. The GD2-GD3 Vaccine appears to be well tolerated, with no reported grade 3 or grade 4 toxicities. To date, more than 230 patients have been treated with the GD2-GD3 Vaccine at Memorial Sloan Kettering Cancer Center (MSK) in New York under a MSK sponsored IND.

“Since Y-mAbs licensed the GD2-GD3 Vaccine in June 2018, we have explored our options to establish commercial scale cGMP production. We believe we now have a viable route forward for manufacturing, and plan to begin using the newly manufactured cGMP drug product in the fourth quarter of 2019. Establishment of a clear path towards approval has been a prerequisite for advancing the GD2-GD3 Vaccine program and we are very excited to move the program forward. We believe the GD2-GD3 Vaccine for relapsed high-risk neuroblastoma may offer meaningful improvement in the long-term treatment paradigm for pediatric patients, serving as a natural extension post immunotherapy treatment with our naxitamab antibody based product candidate,” stated Thomas Gad, Founder, Chairman, President and Head of Business Development and Strategy.
