Liquidity and Capital Resources
Since our inception, we have incurred significant operating losses. We have not yet commercialized any of our product candidates and have generated only limited revenue to date from funding arrangements with our former collaboration partner. While we may generate revenue in the future from the sale of a product candidate, any such revenue would depend on successful regulatory approval and commercial launch. We have historically funded our operations primarily through the public offering and private placement of our securities, issuance of debt and consideration received from our collaborative agreements.
On May 6, 2022, we entered into a Sales Agreement (the “Sales Agreement”) with Guggenheim Securities, LLC (“Guggenheim Securities”), pursuant to which we may issue and sell, from time to time, shares of our common stock having an aggregate offering price of up to $75.0 million through Guggenheim Securities, as the sales agent, in an at the market offering (“ATM”) registered under a shelf registration statement on Form S-3.

On February 10, 2023, we filed a Form S-3ASR with the Securities and Exchange Commission (“SEC”) (“2023 Shelf Registration Statement”) for the issuance of common stock, preferred stock, warrants, rights, debt securities and units, which became effective immediately upon filing. At the time any of the securities covered by the 2023 Shelf Registration Statement are offered for sale, a prospectus supplement will be prepared and filed with the SEC containing specific information about the terms of any such offering.

Pursuant to the Purchase Agreement, the Purchasers purchased (i) an aggregate of 17,717,997 shares of our common stock at a price per share of $7.50, and (ii) 12,280 shares of our Series B Non-Voting Convertible Preferred Stock (“Series B Preferred Stock”), at a price per share of $7,500.00.
