  • IND cleared for SON-1010 and clinical trial initiated; initial safety data for this study are anticipated in the second half of 2022.

  • Research and development expenses were $6.4 million for the three months ended March 31, 2022, compared to $3.8 million for the three months ended March 31, 2021. The increase of $2.6 million was primarily due to the development of the cell lines for SON-1010, SON-1210 and SON-080, and an increase in payroll and share-based compensation expense as we continue to expand our operations.
  • General and administrative expenses were $1.9 million for the three months ended March 31, 2022, compared to $2.2 million for the three months ended March 31, 2021. The decrease of $0.3 million was primarily due to a decrease in payroll expense.
