Industry Context

The pharmaceutical and biotechnology industries are highly competitive, with FibroGen facing competition from companies with greater resources and experience. The increasing generic competition for roxadustat in China highlights the challenges of maintaining market share in a rapidly evolving regulatory landscape.

Comparison to Industry Standards

• The 8.7 months median radiographic progression-free survival (rPFS) observed in the Phase 1 clinical study of FG-3246 in heavily pre-treated, biomarker unselected patients with mCRPC compares favorably to the 5.6-6 months rPFS after switching to a different ARSI, and approximately 8 months with chemotherapy.
• The 10.2 months preliminary estimate of median rPFS in the investigator-sponsored Phase 1b/2 study of FG-3246 in combination with enzalutamide in patients with mCRPC is encouraging.
• The 47.5% transfusion independence rate achieved in the roxadustat arm of the MATTERHORN trial was not statistically significant compared to the placebo arm, but a post-hoc analysis showed a significant benefit in patients with higher transfusion burden.

Legal Proceedings

• The company is involved in ongoing legal proceedings, including derivative lawsuits and an SEC investigation related to roxadustat's pooled cardiovascular safety data.

Related Party Transactions

• The company's collaboration agreements with Astellas and AstraZeneca are related-party transactions.
• The sale of FibroGen International to AstraZeneca Treasury Limited is a related-party transaction.
• The company's joint venture with AstraZeneca, Falikang, is a related-party transaction.

Stakeholder Impact

• Shareholders face the risk of stock price volatility and potential dilution from future equity offerings.
• Employees have experienced workforce reductions and face uncertainty about future employment.
• Patients may benefit from the development of new therapies, but access to existing treatments could be affected by pricing and reimbursement changes.
• Suppliers and creditors may be impacted by the company's financial challenges and restructuring efforts.

Next Steps

• Initiate Phase 2 monotherapy dose optimization study of FG-3246 for the treatment of mCRPC in mid-2025.
• Commence an exploratory study of FG-3180, the PET imaging agent, in conjunction with the Phase 2 study of FG-3246.
• Meet with the FDA in the second quarter of 2025 to discuss the potential path forward for roxadustat in MDS.
• Close the sale of FibroGen International to AstraZeneca Treasury Limited by mid-2025.
• Repay the term loan facility with Morgan Stanley Tactical Value upon the closing of the sale of FibroGen International.
