Item 1.01

Entry into a Material Definitive Agreement

On June 17, 2021, FibroGen, Inc. (“FibroGen”) and HiFiBiO Therapeutics (“HiFiBiO”), a private, multinational clinical-stage biotherapeutics company with expertise in immune modulation and single cell science announced a partnership covering three HiFiBiO programs.

Under the terms of the Exclusive License and Option Agreement, dated June 16, 2021 (the “Agreement”), FibroGen will make a $25 million upfront payment to HiFiBiO, as well as payments upon option exercise. In addition, HiFiBiO may receive up to a total of an additional $1.1B in future option, clinical, regulatory, and commercial milestone payments across all three programs. HiFiBiO will also be eligible to receive mid single-digit to low double-digit royalties based upon worldwide net sales.

FibroGen exclusively licensed all products in the Galectin-9 program and will have sole right to develop them worldwide. The lead product candidate in the Galectin-9 program is expected to enter clinical development in the first quarter of 2023. FibroGen has also obtained exclusive options to license all product candidates in HiFiBiO’s CXCR5 and CCR8 programs. Each option may be independently exercised following delivery of program-specific data to be generated by HiFiBiO. If an option is exercised, FibroGen will have the sole right to develop products from that program worldwide. The lead product candidates from the CXCR5 and CCR8 programs are expected to enter clinical development by the middle of 2023.

The Agreement contains other industry standard license and collaboration terms including related to exclusivity, sublicensing, development, regulatory, manufacturing, commercialization, milestones, royalties, intellectual property, and termination. The Agreement will expire on a product-by-product and country-by-country basis at the end of the applicable royalty term.

The foregoing description of the Agreement is not a complete description thereof, and is qualified in its entirety by reference to the actual Agreement that will be filed with the Securities and Exchange Commission as an exhibit to FibroGen’s Quarterly Report on Form 10-Q for the quarter ending June 30, 2021.

A copy of the press release is furnished as Exhibit 99.1 to this report and is incorporated herein by reference.
