Collaboration and other research and development revenues increased to $5.3 million for the three months ended September 30, 2023, compared to $42.0 thousand for the same period in 2022.

General and administrative expenses decreased by $1.2 million to $15.0 million for the three months ended September 30, 2023, compared to $16.2 million for the same period in 2022. The decrease was driven by reduced headcount related expense, including stock compensation, and reduced legal costs.
