About Y-mAbs Therapeutics

Y-mAbs Therapeutics was founded in 2015 by Thomas Gad, with a mission to develop innovative cancer treatments. The company focuses on creating antibody-based therapies, particularly targeting pediatric oncology.

In its early years, Y-mAbs concentrated on developing a robust pipeline of drug candidates. Their dedication to addressing unmet medical needs in cancer treatment quickly garnered attention in the biotech community.

A significant milestone for Y-mAbs came in September 2018, when the company went public on the NASDAQ under the ticker YMAB. The IPO was a pivotal moment, providing the necessary capital to advance their clinical trials and expand their research capabilities.

Y-mAbs has since made notable progress, particularly with its lead product candidates, which have shown promise in treating neuroblastoma, a rare pediatric cancer. The company's commitment to innovation and patient care continues to drive its research and development efforts.

Today, Y-mAbs stands as a testament to the impact of focused scientific research and the potential of antibody-based therapies in transforming cancer treatment. The journey of Y-mAbs Therapeutics highlights the importance of perseverance and innovation in the biopharmaceutical industry.
