PROSPECTUS

<div align='center'>2,160,166 Shares of Common Stock</div>

This prospectus relates to the proposed resale or other disposition, by the selling stockholders identified in this prospectus, of an aggregate of up to 2,160,166 shares of common stock, par value $0.01 per share, of Indaptus Therapeutics Inc. consisting of (i) 501,566 shares of common stock issued upon the automatic conversion of convertible promissory notes, which were issued in a private placement in June 2025, or the June 2025 Private Placement, (ii) 190,795 shares of common stock issuable upon exercise of pre-funded warrants issued in the June 2025 Private Placement, (iii) 1,384,722 shares of common stock issuable upon the exercise of investor warrants issued in the June 2025 Private Placement, and (iv) 83,083 shares of common stock issuable upon exercise of placement agent warrants issued in connection with the June 2025 Private Placement. We refer to the pre-funded warrants, investor warrants, and placement agent warrants collectively as warrants.

We will not receive any proceeds from the sale of the shares of our common stock by the selling stockholders. All net proceeds from the sale of the shares of our common stock covered by this prospectus will go to the selling stockholders. However, we may receive the proceeds from any exercise of warrants if the holders do not exercise the warrants on a cashless basis. See “Use of Proceeds.”

The selling stockholders and any of their pledgees, donees, transferees, assignees or other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be 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. See “Plan of Distribution.”
