Subsequent Events [Text Block]	*Note 16.* Subsequent Events** On October 1, 2024, we closed a registered direct offering (the “Offering”) pursuant to a placement agency agreement with Canaccord, pursuant to which Canaccord acted as our exclusive placement agent in connection with the offer and sale of 725,000 shares of Common Stock and pre-funded warrants to purchase up to 17,626 shares of Common Stock at an exercise price of $0.001 per share. The aggregate gross proceeds from the Offering were approximately $3.5 million, before deducting placement agent fees and expenses and other expenses payable by us. We paid Canaccord a placement agent fee of 6.00% of the aggregate gross proceeds of the Offering. The Offering was made pursuant to our registration statement on Form S-3 (file number 333-264299), which was declared effective on April 26, 2022, and our prospectus supplement relating to the Offering. Additionally, in separate, concurrent Private Placements, we also sold 379,930 shares of Common Stock, pre-funded warrants to purchase up to 424,358 shares of Common Stock at an exercise price of $0.001 per share, and warrants to purchase up to 1,546,914 shares of Common Stock at an exercise price of $4.82 per share. The aggregate gross proceeds from the Private Placements were approximately $3.8 million, of which $1.3 million was contributed by certain of our directors, executive officers and their affiliated entities. The Private Placements closed on October 1, 2024 and as of September 30, 2024, we had received cash of $3.8 million which we recorded as share subscriptions payable on the condensed consolidated balance sheets. We are currently evaluating the accounting for the proceeds from the Offering and Private Placements and the classification of the associated equity securities.
