Research and Development Expenses. Research and development expenses were $2.7 million, net of collaboration funding of $2.2 million, for the three months ended September 30, 2022, as compared to $1.4 million, net of collaboration funding of $3.5 million, for the three months ended September 30, 2021. This increase of $1.3 million was primarily due to increases in expenses for clinical studies related to ACER-801 and EDSIVO™, contract research, and employee-related expenses, partially offset by decreases in expenses related to contract manufacturing. Research and development expenses related to ACER-001 decreased in the three months ended September 30, 2022, resulting in a decrease in the recognition of the collaboration funding from the Collaboration Agreement with Relief. Research and development expenses for the three months ended September 30, 2022 were comprised of $2.3 million related to ACER-001, offset by $2.2 million of collaboration funding; $1.2 million related to ACER-801; $1.0 million related to EDSIVO™; and $0.4 million related to other development activities. General and Administrative Expenses. General and administrative expenses were $2.6 million, net of collaboration funding of $1.4 million, for the three months ended September 30, 2022, as compared to $1.8 million, net of collaboration funding of $1.0 million, for the three months ended September 30, 2021. This increase of $0.8 million was primarily due to increases in employee-related expenses, precommercial expenses, and audit and consulting fees, partially offset by an increase in the recognition of the collaboration funding from the Collaboration Agreement with Relief. Net Loss. Net loss for the three months ended September 30, 2022 was $5.0 million, or $0.31 net loss per share (basic and diluted), compared to a net loss of $3.3 million, or $0.23 net loss per share (basic and diluted), for the three months ended September 30, 2021.
