product pipeline / R&D affecting expense
“The increase in research and development expenses was primarily attributable to: • a net increase of $0.9 million in unallocated materials and other support costs for our pipeline products; and • a net increase of $0.8 million in R&D payroll and manufacturing costs driven by the timing of production runs across our product candidates and programs, mainly due to an increase in KB111, KB407, and KB803, partially offset by a decrease in B-VEC.”
