Over $11 million raised since the beginning of 2Q 2025 Cash runway extended into the second half of 2026 In the INVINCIBLE-4 Study, patients receiving INT230-6 prior to the start of standard of care achieved high levels of tumor necrosis in 8 days INT230-6 achieved 100% complete response rate in preclinical models of malignant peripheral nerve sheath tumors SHELTON, Conn., Aug. 7, 2025 /PRNewswire/ -- Intensity Therapeutics, Inc. ("Intensity" or "the Company") (Nasdaq: INTS), a late-stage clinical biotechnology company focused on the discovery and development of novel intratumoral cancer therapies that are designed to kill tumors and increase immune system recognition of cancers using its proprietary non-covalent conjugation technology, announces second quarter 2025 financial results and provides a corporate update. Corporate Update INVINCIBLE-4 Study: Phase 2 randomized open-label, multicenter study to analyze the clinical activity, safety, and tolerability of INT230-6 given before administration of the standard of care ("SOC") treatment in patients with early-stage, operable triple-negative breast cancer and SOC alone. The primary endpoint is the change in the pathological complete response rate for the combination compared to the SOC alone. In April, the European Medicines Agency authorized the initiation of the INVINCIBLE-4 Study in France in collaboration with Unicancer (UCBG), the French referent cooperative group in breast cancer accredited by the French National Cancer Institute (INCa). The INVINCIBLE-4 Study is currently recruiting patients in Switzerland and France. The expected total is 54 patients. In June 2025 we showed images from the trial of a patient who received two doses of INT230-6. Prior to the injections, the tumor was active. In the post INT230-6 injection scans, the tumor became dark with only diminished live cancer observed at the interface of the healthy tissue and necrotic tumor. INVINCIBLE-3 Study: Phase 3 open-label, randomized study testing INT230-6 as monotherapy compared to the SOC drugs in second and third line treatment for specific soft tissue sarcoma subtypes. This study has been authorized by the US FDA, Health Canada, the European Medicines Agency (for France, Germany, Italy, Poland, and Spain), and Australia's Therapeutic Goods Administration. The primary endpoint in the INVINCIBLE-3 Study is overall survival. In March 2025, new patient enrollment and site activations were paused due to funding issues; however, patients who were already enrolled continue to be dosed, followed and monitored. Capital Raises and Cash Runway: Since the beginning of the second quarter of 2025, the Company has raised an aggregate of $11.3 million, with net proceeds of approximately $10.1 million in two public offerings and At-the Market offerings (the "ATM"), and has extended its cash runway into the second half of 2026. In April 2025, the Company entered into a Securities Purchase Agreement with certain institutional investors participating in a public offering and raised an aggregate of $2.35 million, with net proceeds after deducting the fees and expenses of approximately $1.9 million. In June 2025, the Company entered into an Underwriting Agreement with ThinkEquity LLC in a public offering and raised an aggregate of $2.3 million, with net proceeds after deducting the fees and expenses of approximately $1.8 million. In July 2025, the Company raised an aggregate of $6.6 million via its ATM, with net proceeds after deducting the fees and expenses of approximately $6.3 million. "In a challenging financial market, we were able to raise capital and lower our burn rate during the second quarter to continue to treat patients in our two studies, and in July 2025, high liquidity in our stock allowed us to raise additional gross proceeds of $6.6 million at a lower incremental cost. This new capital extends our operating runway considerably, with the remaining capacity under the ATM facility to be used selectively and strategically. Given the capital raised to date, we also believe that we are now compliant with Nasdaq's minimum stockholders' equity listing requirements, pending Nasdaq's confirmation," stated Lewis H. Bender, Intensity Founder, President, and CEO. "In the INVINCIBLE-4 Study, scan images indicate a substantial decrease in tumor activity following two doses of our drug as patients begin their immune-chemo regimen. Based on our prior studies, we believe this effect should be beneficial in increasing the pathological response rate in the cohort of patients receiving our drug and expect to obtain pathology data in 2H of 2026. Lastly, as always, the Company is driven by a focus on patients. This quarter, we strengthen that commitment by forming a collaboration with the author, model, executive producer, speaker, and breast cancer survivor Christine Handy to raise patient awareness of new treatment options on the horizon for patients with early-stage disease." Second Quarter 2025 Financial Results Research and development expenses were $1.5 million for the three months ended June 30, 2025, compared to $3.6 million for the same period in 2024. Clinical trial expenses decreased $1.5 million primarily due to lower INVINCIBLE-3 Study costs. In March 2025, the Company paused new site activations and patient enrollments in the INVINCIBLE-3 Study, due to funding constraints. Prior to this pause, the trial had enrolled 23 patients. The Company will continue to treat all patients enrolled in this study in cooperation with our third-party contract research organizations during this pause, and once sufficient funding is obtained, the Company plans to restart site activations and patient enrollment. General and administrative expenses were $1.2 million for the three months ended June 30, 2025, compared to $1.5 million for the same period in 2024. Insurance expense decreased due to the favorable directors and officers insurance renewal terms compared to the prior policy year, and legal and other expenses decreased as a result of cost saving from the integration of new systems in the administrative areas. Overall, net loss was $2.5 million for the three months ended June 30, 2025, compared to a net loss of $5.0 million for the three months ended June 30, 2024. As of June 30, 2025, cash and cash equivalents totaled $2.2 million. About INT230-6 INT230-6, Intensity's lead proprietary investigational product candidate, is designed for direct intratumoral injection. INT230-6 was discovered using Intensity's proprietary DfuseRx℠ technology platform. The drug consists of two proven, potent anti-cancer agents, cisplatin and vinblastine sulfate, and a diffusion and cell penetration enhancer molecule ("SHAO") that facilitates the dispersion of potent cytotoxic drugs throughout tumors, allowing the active agents to diffuse into cancer cells. These agents remain in the tumor, resulting in a favorable safety profile. In addition to local disease control and direct tumor killing, INT230-6 causes a release of a bolus of neoantigens specific to the malignancy, leading to immune system engagement and systemic anti-tumor effects. Importantly, these effects are mediated without immunosuppression, which often occurs with systemic chemotherapy. About Intensity Therapeutics Intensity is a late-stage clinical biotechnology company whose novel engineered chemistry enables aqueous cytotoxic-containing drug formulations to mix and saturate a tumor's dense, high-fat, pressurized environment following direct intratumoral injection. As a result of the saturation, Intensity's clinical trials have demonstrated the ability of INT230-6 to kill tumors and elicit an adaptive immune response within days of injection, representing a new approach to cancer cell death that holds the potential to shift the treatment paradigm and turn many deadly cancers into chronic diseases even for malignancies that do not respond to conventional immunotherapy. Intensity has completed two clinical studies and enrolled over 200 patients using INT230-6; a Phase 1/2 dose escalation study in metastatic cancers including sarcomas (NCT03058289), and a Phase 2 randomized control clinical trial in locally advanced breast cancer (the "INVINCIBLE-2 Study") (NCT04781725) in women without undergoing chemotherapy prior to their surgery. The Company initiated a Phase 3 trial in soft tissue sarcoma (the "INVINCIBLE-3 Study") (NCT06263231), testing INT230-6 as second or third line monotherapy compared to the standard of care ("SOC") with overall survival as an endpoint. Intensity also initiated a Phase 2 study (the "INVINCIBLE-4 Study") (NCT06358573) in collaboration with the Swiss Cancer Group, formerly the Swiss Group for Clinical Cancer Research SAKK, as part of a Phase 2/3 program evaluating INT230-6 followed by the SOC immunochemotherapy and the SOC alone for patients with presurgical triple-negative breast cancer. Pathological complete response ("pCR") is the endpoint.

• Cash runway extended into the second half of 2026 • Average sales price per share was over 10% higher than the June 2025 public offering price SHELTON, Conn., Aug. 4, 2025 /PRNewswire/ -- Intensity Therapeutics, Inc. (Nasdaq: INTS) ("Intensity" or "the Company"), a late-stage clinical biotechnology company focused on the discovery and development of novel intratumoral cancer therapies that are designed to kill tumors and increase immune system recognition of cancers using its proprietary non-covalent conjugation technology, announces that in July 2025 the Company added $6.6 million in gross proceeds ($6.3 million net) by selling 19,868,658 shares of its common stock via its At-the-Market offering (the "ATM") at an average price of $0.3323 per share. Following such sales of common stock pursuant to the ATM, the Company has 46,035,081 shares of common stock issued and outstanding as of July 31, 2025. "We were able to take advantage of strong liquidity and favorable prices in our stock last month. The proceeds from these ATM sales strengthen our balance sheet considerably and allow us to continue to advance the clinical trials into the second half of 2026," said Lewis H. Bender, President and CEO of Intensity. "We are also pleased to announce that the average price per share for these ATM sales was more than 10% higher than our recently completed June 2025 public offering, and the costs to raise this incremental capital were much lower. We will continue to be selective and strategic in the deployment of the remainder of the ATM." About At the Market Transactions "At-the-Market" (ATM) offerings, also known as "ATM" programs, refer to a method where a public company sells its newly issued shares directly into the existing trading market at the prevailing market price, rather than through a traditional underwritten offering. This approach allows companies to raise capital opportunistically and incrementally, as needed, with minimal disruption to the market and typically lower costs.
