Biggest changeOperating costs and expenses decreased for the year ended December 31, 2022 compared to the prior year as a result of the net effect of the following: • $60.0 million for acquired in-process research and development asset from HiFiBiO Therapeutics (“HiFiBiO”) in the prior year, which did not recur in the current year; • $19.1 million lower employee-related expenses and $5.6 million lower stock-based compensation expenses primarily due to lower headcount as part of the cost reduction effort we started to implement in the second half of 2021 following the CRL for roxadustat in CKD anemia in the U.S., and payroll tax refunds received during the year ended December 31, 2022, partially offset by overall merit increase during the current year; • $15.0 million lower clinical trial expenses associated with roxadustat post-approval safety studies and Phase 3 trials for pamrevlumab; • $2.3 million lower outside services expenses due to lower promotional expenses and sample costs for roxadustat in China. • $7.4 million higher cost of goods sold due to higher roxadustat product sales; • $7.1 million higher drug development expenses associated with drug substance and drug product manufacturing activities primarily related to pamrevlumab; and • $6.7 million higher legal expenses primarily due to a one-time favorable patent-related court ruling recorded in the prior year.
Biggest changeTotal operating costs and expenses decreased $12.2 million for the year ended December 31, 2023 compared to the prior year as a result of the net effect of the following: • $37.8 million lower drug development expenses associated with drug substance and drug product manufacturing activities related to roxadustat post-approval safety studies in China and pamrevlumab which were largely completed in the prior periods; • $14.8 million lower stock-based compensation primarily resulting from significantly lower stock price and cancellations of stock options and restricted stock units; • $3.8 million lower legal expenses primarily due to lower corporate legal activities; • $24.6 million one-time, non-cash charge of acquired in-process research and development (“IPR&D”) expenses associated with the recent exclusive license for FG-3246 from Fortis Therapeutics (“Fortis”) and the acquisition of Fortis; • $12.6 million of restructuring charge recorded in the third quarter of 2023 related to reduction in force actions in July 2023; • $4.8 million higher employee-related expenses primarily due to the impact from payroll tax refunds received during 2022 that did not recur in the current year, as well as more business travel activities and higher severance during the current year period, offset by the impact from reduction in force actions in July 2023; and • $3.7 million higher outside services expenses due to higher consulting activities in roxadustat post-approval safety studies and efforts to prepare for commercialization in the first half of the year. 72 Our research and development expenses were $282.9 million, $296.8 million and $387.0 million for the years ended December 31, 2023, 2022 and 2021, respectively.
The accrued and other liabilities were also impacted by the classification of a portion of accrued co-promotion expenses from other long-term liabilities to current liabilities based on the updated estimate of timing for payment, and by the timing of invoicing and payment; • Accounts payable increased $5.9 million, primarily driven by the timing of invoicing and payments; • Prepaid expenses and other current assets decreased $4.9 million, primarily due to the collection of $8.0 million from Eluminex for upfront license payment during the first quarter of 2022, and less prepayments made for roxadustat API manufacturing activities, partially offset by a payroll tax refund recorded as other receivables as of December 31, 2022 and received in the first quarter of 2023; • Other long-term liabilities decreased $18.3 million primarily driven by the above-mentioned classification of a portion of accrued co-promotion expenses from other long-term liabilities to current liabilities based on the updated estimate of timing for payment; • Inventories increased $11.0 million, driven by the increased inventory level primarily related to inventory cost capitalized related to Europe and other territories, and FibroGen Beijing’s productions of roxadustat for commercial sales purposes; and • Deferred revenue decreased $4.1 million, primarily related to revenue recognized from the previously deferred revenue of the China performance obligation during the year ended December 31, 2022, and the above-mentioned reclassification to accrued liabilities, resulting from changes in estimated variable consideration associated with the API or bulk drug product deliveries fulfilled with Astellas and AstraZeneca.
