Up to 5,000,000 Shares of Common Stock</div>

This prospectus relates to the resale, from time to time, of up to 5,000,000 shares of our common stock, par value $0.00001 per share, by Lincoln Park Capital Fund, LLC, which we refer to in this prospectus as “Lincoln Park” or the “selling stockholder.”

The shares of common stock to which this prospectus relates are shares that have been or may be issued by us to Lincoln Park pursuant to the purchase agreement dated September 15, 2025, that we entered into with Lincoln Park (the “Purchase Agreement”). See “The Lincoln Park Transaction” for a description of that agreement and “Selling Stockholder” for additional information regarding Lincoln Park.

We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of shares by the selling stockholder. However, we may receive up to $10,000,000 in aggregate gross proceeds under the Purchase Agreement from any sales of common stock we make to Lincoln Park pursuant to the Purchase Agreement, from time to time in our discretion, after the date of the registration statement of which this prospectus is a part is declared effective and the other conditions in the Purchase Agreement have been satisfied.

The selling stockholder may sell or otherwise dispose of the shares of common stock described in this prospectus in a number of different ways and at varying prices. See “Plan of Distribution” beginning on page 25 of this prospectus for more information about how the selling stockholder may sell or otherwise dispose of the shares of our common stock being offered through this prospectus. The selling stockholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the “Securities Act”).

The selling stockholder will pay all brokerage fees and commissions and similar expenses in connection with any resale or other disposition of the common stock described in this prospectus by the selling stockholder. We will pay the expenses incurred in registering, under the Securities Act, the offer and resale of such shares of common stock by the selling stockholder, including legal and accounting fees. See “Plan of Distribution”.

Our common stock is listed on the Nasdaq Capital Market LLC (“
