SHELTON, Conn., Dec. 5, 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, today announced that it has been granted a 180 calendar day extension from The Nasdaq Stock Market LLC ("Nasdaq") to regain compliance with the Nasdaq's minimum $1.00 bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) (the "Rule") for continued listing on Nasdaq (the "Minimum Bid Price Requirement"), following the expiration of the initial 180 calendar day period to regain compliance on December 3, 2025, which was initially granted on June 6, 2025. The Company now has until June 1, 2026 to meet the Minimum Bid Price Requirement set forth in Nasdaq Listing Rule 5550(a)(2).

The notification has no immediate effect on the listing or trading of the Company's shares of common stock, which will continue to trade on the Nasdaq Capital Market under the symbol "INTS." To regain compliance with the Rule, the Company must maintain a closing bid price of at least $1.00 per share for a minimum of ten (10) consecutive business days on or prior to the 180-day extension period, or June 1, 2026. The Company intends to actively monitor the closing bid price of its common stock between now and the end of the extension period and intends to take all appropriate actions to cure the deficiency and regain compliance with the Rule prior to the end of the compliance period.

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.

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.
