(all deemed not related to treatment) and three experienced treatment-emergent SAEs in the 300mg group, including hematuria, abdominal pain, and infection (all deemed not related to treatment) and recurrent presyncope (deemed related to treatment). At the 300mg dose, nine participants experienced treatment-emergent liver enzyme test (“LFT”) increases (greater than 3xULN), which subsided after cessation of drug without evidence of serious liver injury. There were no LFT elevations observed in the 100mg dose.
We have enrolled 130 patients in the Phase 2 COG1201 (SHIMMER) study of CT1812 in mild-to-moderate dementia with Lewy bodies, or DLB. The design of this trial is a double-blind, randomized, six-month trial involving three dose groups, two active treatment cohorts and a placebo group. Clinical endpoints of the trial include safety and physical activity measurements, cognitive assessments, and PK and pharmacodynamic biomarker analyses compared to baseline measurements recorded at the beginning of the trial. In addition, cerebrospinal fluid will be collected and analyzed for α-synuclein content and established patterns of differential protein expression. This study is not powered to show significance in the efficacy endpoints. We expect to report topline results from our SHIMMER trial by year-end 2024.
Since our inception in 2007, we have incurred significant operating losses and devoted substantially all of our time and resources to developing our lead product candidate, CT1812, building our intellectual property portfolio, raising capital and recruiting management and technical staff to support these operations. As of June 30, 2024, we had an accumulated deficit of $157.4 million. We incurred a net loss of $7.0 million and $16.2 million for the three and six months ended June 30, 2024, respectively, and net loss of $4.7 million and $10.9 million for the three and six months ended June 30, 2023, respectively.
To date, we have funded our operations primarily with proceeds from grants awarded by the National Institute of Aging (the “NIA”), a division of the National Institutes of Health (the “NIH”), and proceeds from our initial public offering (the “IPO”), completed in October 2021, proceeds from our follow-on public offerings, sales of our common stock through our ATM (as defined below), sales of our convertible promissory notes, convertible preferred stock, simple agreements for future equity (“SAFE”) and stock option exercises. Since our inception, we have received approximately $171.0 million in cumulative grant awards to fund our clinical trials, primarily from the NIA, and we have raised approximately $125.9 million in net proceeds from sales of our equity securities, convertible notes, SAFE, stock option exercises, IPO and follow-on public offerings, ATM, and equity line financing with Lincoln Park. As of June 30, 2024, we had cash and cash equivalents of $28.5 million. To date, $57.3 million of the cumulative grant funds remain available.
On December 23, 2022, we entered into a sales agreement with Cantor Fitzgerald & Co. and B. Riley Securities, Inc. (the “Sales Agents”), providing for the offering, issuance and sale by us of up to $40.0 million of our common stock from time to time in “at-the-market” offerings (the “ATM”). We sold 191,273 shares of common stock under the ATM during the six months ended June 30, 2024 for gross proceeds of approximately $0.4 million. As of June 30, 2024, there was approximately $34.3 million of common stock remaining available for sale under the ATM.
On March 10, 2023, we entered into a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) for an equity line financing (the “Lincoln Park Purchase Agreement”). The Lincoln Park Purchase Agreement provides that, subject to the terms and conditions set forth therein, we have the right, but not the obligation, to direct Lincoln Park to purchase up to $35.0 million of shares of common stock at our sole discretion, over a 36-month period commencing on March 10, 2023. We filed a prospectus supplement to our registration statement on Form S-3 (File No. 333-268992) covering the resale of shares of common stock that are issued under the Lincoln Park Purchase Agreement. During the six months ended June 30, 2024, we did not sell any shares of common stock to Lincoln Park. As of June 30, 2024, $34.8 million was available to draw pursuant to the Lincoln Park Purchase Agreement.
On March 14, 2024, we completed our follow-on public offering, pursuant to which we issued and sold 6,571,428 shares of our common stock at a public offering price of $1.75 per share. On March 28, 2024, the underwriters exercised their option to purchase 985,714 shares of our common stock at a public offering price of $1.75 per share. In connection with the follow-on public offering, we received net proceeds of approximately $11.9 million, after deducting underwriting discounts and commissions and other offering related expenses.
We expect to continue to incur significant and increasing expenses and net losses for the foreseeable future, as we advance our current and future product candidates through preclinical and clinical development, manufacture drug product
