Personnel-related expenses and related share-based compensation decreased by $0.3 million and $0.2 million, respectively, primarily due to reduction in general and administrative headcount for the three months ended March 31, 2023, as compared to the same period in 2022. Insurance, facilities fees and other related costs, and professional and consultant fees remained consistent between the three months ended March 31, 2023 and 2022.
