Within our acute care franchise, we are also developing HTX-019, an investigational agent for the prevention of postoperative nausea and vomiting (“PONV”) and HTX-034, an investigational agent, our next-generation product candidate for the management of postoperative pain (collectively, our “Product Candidates”).

Based on our current operating plan and projections, management believes that the Company’s cash, cash equivalents and short-term investments, including the net proceeds from the August 8, 2022 private placement, will be sufficient to meet the Company’s anticipated cash requirements for at least one year from the date this Quarterly Report on Form 10-Q is filed with the U.S. Securities and Exchange Commission (“SEC”). Based on our cash balance of $83.5 million at June 30, 2022, without taking into account the net proceeds from the private placement noted above, there is substantial doubt about our ability to continue as a going concern for at least one year from the date this Quarterly Report on Form 10-Q is filed with the SEC.
