• The safety and efficacy of FG-3165 will be evaluated in a Phase 1 trial in select solid tumors
• Plan to begin enrollment in 2H 2024

SAN FRANCISCO, June 03, 2024 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) today announced that the U.S. Food and Drug Administration (FDA) has cleared the Company’s Investigational New Drug (IND) of FG-3165, a galectin-9 (Gal9) targeted monoclonal antibody under development for treatment of solid tumors characterized by high Gal9 levels of expression.

“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,” said Thane Wettig, Chief Executive Officer of FibroGen. “To date, FG-3165 has demonstrated anti-tumor activity with improved survival in combination with other immune modulatory therapies in mouse cancer models and has shown excellent tolerability in nonclinical safety studies. We are excited to begin enrollment in a Phase 1 trial in the second half of this year and explore the potential of FG-3165 in enhancing anti-tumor immune responses in the tumor microenvironment.”

The FDA IND clearance enables FibroGen to initiate a Phase 1 clinical trial evaluating the safety and efficacy of FG-3165 in patients with select solid tumors. The trial is anticipated to begin enrollment in the second half of 2024.

About FG-3165

FG-3165 is a galectin-9 (“Gal9”) targeted antibody under development for treatment of solid tumors and potentially hematologic malignancies characterized by high Gal9 levels of expression. Gal9 has been reported to signal through multiple immune checkpoints on lymphocytes, including TIM3, VISTA, and PD-1, suppressing T and natural killer cell activation. FG-3165 selectively binds to Gal9 with high affinity and inhibits its ability to induce lymphocyte cell death, resulting in enhanced tumor cell killing.

Toxicology material as well as GMP material for the upcoming Phase 1 clinical trial was manufactured in partnership with Just-Evotec Biologics.
