SEOUL, South Korea--(BUSINESS WIRE)--Genexine (KOSDAQ:095700, CEO Neil Warma), a publicly traded, clinical-staged Korean biopharmaceutical company committed to the discovery and development of novel biologics for the treatment of unmet medical needs, today announced positive topline results from the multi-center, randomized, open-label, active-controlled pivotal phase 3 study (CTJ101PGHD301) being conducted in China to evaluate the efficacy and safety of eftansomatropin alfa (Genexine’s proprietary long-acting growth hormone, also known as GX-H9) in children with growth hormone deficiency.
The study being conducted by Genexine’s partner in China, I-Mab, met its primary endpoint of annualized height velocity (AHV) at week 52 and demonstrated that eftansomatropin alfa was non-inferior to Norditropin®. Eftansomatropin alfa was given by weekly injection vs. Norditropin® given by daily injection. The mean AHV was 10.76 (cm/year) for eftansomatropin alfa vs. 10.28 (cm/year) for Norditropin®, with a difference of 0.47 [95% CI -0.06,1.00] and non-inferiority p-value <0.0001. Eftansomatropin alfa was well tolerated and no drug discontinuation was reported due to treatment related adverse events. The safety profile of eftansomatropin alfa was comparable to Norditropin®. The Company is planning to file a BLA submission in China in 2024.
“We are pleased with the results from this registration trial as this demonstrates clear safety and efficacy in this potential best-in-class drug to treat children with growth hormone deficiency,” said Neil Warma, Genexine President and CEO. “This is a significant milestone for Genexine as we demonstrate our ability to bring our novel products to market and the value of our proprietary long-acting hyFc® platform. We are excited to be preparing to submit the BLA in 2024 and advancing this product to market and to patients in China. We remain committed to our efforts to commercialize our leading products in various key markets.”
About Eftansomatropin alfa (long-acting recombinant human growth hormone)
GX-H9 has been developed utilizing Genexine’s hyFc® platform as a treatment for growth hormone deficiency (GHD). GX-H9 is currently being evaluated in a phase 3 registration trial in pediatric GHD in China with a BLA submission expected in 2024. GX-H9 is a potential best-in-class product that is differentiated by its extended half-life resulting in significantly fewer injections (weekly versus daily) and its improved safety profile. Patient compliance has been dramatically improved, which is critical for the pediatric population. GX-H9 is being co-developed with Handok under a strategic partnership and with I-Mab for development in greater China. I-Mab has partnered with Jumpcan for product launch and commercialization of eftansomatropin alfa in China.
