FibroGen, Inc. (NASDAQ:FGEN) recently announced a milestone in its oncology pipeline. The U.S. Food and Drug Administration (FDA) has cleared the Company's Investigational New Drug (IND) application for FG-3165, a novel galectin-9 (Gal9) targeted monoclonal antibody. This clearance allows FibroGen to initiate clinical trials aimed at evaluating the safety and efficacy of FG-3165 in treating patients with solid tumors characterized by high Gal9 levels of expression.
Thane Wettig, the Chief Executive Officer of FibroGen, expressed enthusiasm about this development, stating, "The FDA's IND clearance is an important achievement for us, and we are pleased to advance another product from our promising oncology pipeline into the clinic." Wettig highlighted that FG-3165 has already shown promising anti-tumor activity and improved survival rates in preclinical models when combined with other immune modulatory therapies. Additionally, nonclinical safety studies have demonstrated excellent tolerability of the drug.
Understanding FG-3165 and Galectin-9
FG-3165 is designed to specifically target galectin-9, a protein that plays a critical role in immune regulation. Gal9 signals through multiple immune checkpoints on lymphocytes, including TIM3, VISTA, and PD-1, which are known to suppress the activation of T cells and natural killer cells. By binding selectively to Gal9 with high affinity, FG-3165 inhibits its capacity to induce lymphocyte cell death. This inhibition can result in enhanced tumor cell killing, making FG-3165 a potent candidate for cancer immunotherapy.
Preclinical Promise and Future Prospects: Preclinical studies have demonstrated that FG-3165, in combination with other immune modulatory therapies, can significantly improve anti-tumor activity and survival rates. This has been observed in mouse models of cancer where the drug showed effectiveness in enhancing immune responses within the tumor microenvironment. These promising results have set the stage for the upcoming Phase 1 clinical trial, which aims to evaluate the safety and efficacy of FG-3165 in human subjects. The Phase 1 trial is scheduled to begin enrollment in the second half of 2024, marking the first step in a rigorous process to bring this innovative treatment to patients. This trial will focus on select solid tumors known to exhibit high levels of Gal9 expression.
For the upcoming clinical trials, FibroGen has partnered with Just-Evotec Biologics to manufacture the necessary toxicology and Good Manufacturing Practice (GMP) materials. This collaboration ensures that FG-3165 is produced to the highest standards, providing a robust foundation for its clinical evaluation.
