The Company also announced today that it has decided to close and unblind both its Phase 2b clinical trial of zelnecirnon (RPT193) in atopic dermatitis ("AD") and its Phase 2a trial of zelnecirnon in asthma. Both clinical trials were placed on clinical hold by the FDA in February 2024 based on a serious adverse event of liver failure requiring transplant in one patient in the AD trial. Prior to the imposition of the clinical hold, a total of 229 patients had been enrolled in the Phase 2b AD trial, of which approximately 110 had completed the 16-week dosing period.
"Although there were a significant number of patients who were unable to complete the AD trial due to the hold, we believe we will have sufficient data, even if not statistically significant, to inform our path forward and support our discussions with the FDA," said Brian Wong, President and CEO. "We are working with the clinical trial sites to clean the data and we anticipate that our analysis of the data will be completed in the third quarter of this year. Concurrently, we are continuing our investigation and analysis of the serious adverse event that triggered the clinical hold."
Financial Results for the First Quarter March 31, 2024
First Quarter Ended March 31, 2024
Net loss for the first quarter of 2024 was $30.5 million, compared to $29.3 million for the first quarter of 2023.
Research and development expenses for the first quarter of 2024 were $24.8 million, compared to $25.6 million for the same period in 2023. The decrease in research and development expenses was primarily due to lower development costs related to zelnecirnon, tivumecirnon and early-stage programs as well as decreased expenses for lab supplies partially offset by increased expenses for personnel, consultants, facilities and non-cash stock-based compensation.
General and administrative expenses for the first quarter of 2024 were $7.7 million, compared to $6.0 million for the same period in 2023. The increase in general and administrative expenses was primarily due to increased expenses for personnel, non-cash stock-based compensation, consulting and facilities.
As of March 31, 2024, the Company had cash and cash equivalents and marketable securities of $141.6 million.
