785,402 Shares of Common Stock
This prospectus relates to the
resale of up to an aggregate of 785,402 shares of our common stock, par value of $0.01 per share, or the Resale Shares, by MAM Eagle Lender, LLC, or the Selling Shareholder, including its permitted transferees, donees, pledgees, assignees or successors-in-interest, or its respective successors, from time to time, issuable upon the exercise of warrants we issued to the Selling Shareholder in May 2020 and March
2023, respectively, which we refer to herein as the 2020 Warrants and the 2023 Warrants, respectively, and collectively, the Warrants. For information about the Selling Shareholder, see The Selling Shareholder on page 9.
We are not selling any shares of common stock and will not receive any of the proceeds from the sale of the Resale Shares by the Selling Shareholder, pursuant
to this prospectus. However, we will receive the proceeds of any cash exercise of the Warrants, if any. See Use of Proceeds beginning on page 8 of this prospectus for more information.
We are registering the offer and sale of the Resale Shares pursuant to a Registration Rights Agreement entered into between us and the Selling Shareholder on
March 29, 2023, or the Registration Rights Agreement, in connection with that certain Amendment No. 5 and Consent to Credit Agreement, or Amendment No. 5, entered into by and among us, Baudax Bio N.A. LLC, Baudax Bio Limited, Wilmington
Trust, National Associate, solely in its capacity as administrative and collateral agent and the lenders party thereto, or Amendment No. 5. The Selling Shareholder identified in this prospectus may offer the Resale Shares from time to time
through public or private transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. The registration of
the Resale Shares on behalf of the Selling Shareholder, however, does not necessarily mean that the Selling Shareholder will offer or sell its Resale Shares under this registration statement at any time in the near future or at all. We cannot
predict when, or in what amounts, the Selling Shareholder may sell any of the Resale Shares. The timing and amount of any sale of the Resale Shares is within the sole discretion of the Selling Shareholder. We will pay the expenses of registering
these Resale Shares, including legal and accounting fees. All selling and other expenses incurred by the Selling Shareholder will be borne by the Selling Shareholder. For additional information on the possible methods of sale that may be used by the
Selling Shareholder, see Plan of Distribution beginning on page 19 of this prospectus.
Investing in our common stock
involves a high degree of risk. You should consider carefully the risk factors beginning on page 8 of this prospectus before purchasing any of the Resale Shares offered by this prospectus.

we are not in compliance with Nasdaqs (i) minimum bid price requirement of at least $1.00 per share and (ii) the requirement to have at least $2,500,000 in shareholders equity. To maintain listing on the Nasdaq Capital Market,
we must demonstrate compliance with the Nasdaq initial listing requirements by or before November 13, 2023, or our common stock will become subject to delisting. See Risk Factors If we are unable to meet the initial listing
standards of Nasdaq by November 13, 2023, or otherwise regain compliance with the listing standards of Nasdaq, our common stock may become delisted, which could have a material adverse effect on the liquidity of our common stock and our ability
to raise capital.
