SAN FRANCISCO, Jan. 07, 2026 (GLOBE NEWSWIRE) -- FibroGen, Inc. (Nasdaq: FGEN), today announced it is rebranding the company to Kyntra Bio, representing the next step of the transformation of the Company and its focus on oncology and rare disease assets. The Company’s common stock will begin trading under the new Nasdaq symbol “KYNB” at stock market open on January 8, 2026.

“2025 was a transformational year, highlighted by the sale of FibroGen China, the payoff of our senior secured term loan, and the extension of our cash runway into 2028. We begin this year as Kyntra Bio, a name that captures our company journey and evolution and reflects our purposeful move to a company obsessed with creating outsized impact for patients and shareholders,” said Thane Wettig, Chief Executive Officer of Kyntra Bio. “Today, with a sharpened direction, Kyntra Bio is laser-focused on our mid- and late-stage assets – specifically, FG-3246, our first-in-class, CD46 targeting antibody drug conjugate, and FG-3180, our companion PET imaging agent, currently in a Phase 2 monotherapy trial in prostate cancer, and roxadustat, our Phase 3 ready asset, for which we recently received Orphan Drug Designation in myelodysplastic syndromes. We are thrilled to move forward with renewed purpose into this bold era for our company and are excited for what is in front of us.”

Recent Highlights and Upcoming Milestones

FG-3246 (CD46 Targeting ADC) and FG-3180 (CD46 Targeting PET Imaging Agent)

  • Topline results from the investigator-sponsored Phase 1b/2 study, conducted by UCSF, of FG-3246 in combination with enzalutamide in patients with mCRPC are expected to be presented at ASCO GU in the first quarter of 2026.
  • Interim results from the recently commenced Phase 2 monotherapy trial are expected in the second half of 2026. The trial will also assess the diagnostic performance of FG-3180 to determine the potential correlation between CD46 expression and response to FG-3246.

Roxadustat

  • Granted Orphan Drug Designation from the FDA for the treatment of myelodysplastic syndromes (MDS).
  • Submitted the pivotal Phase 3 clinical trial protocol for roxadustat for the treatment of anemia in patients with lower-risk MDS and high transfusion burden to the U.S. Food and Drug Administration.

In addition to the new name, the Company is refreshing its corporate website to better reflect the Company’s strategy moving forward. The CUSIP number for the Company’s common stock is not affected by the name change.
