SHELTON, Conn., March 13, 2025 /PRNewswire/ -- Intensity Therapeutics, Inc. ("Intensity" or "the Company") (Nasdaq: INTS), a late-stage clinical biotechnology company focused on the discovery and development of proprietary, novel immune-based intratumoral cancer therapies designed to kill tumors and increase immune system recognition of cancers, announces 2024 year-end financial results and provides a corporate update.

Corporate Update

INVINCIBLE-3 Study: Phase 3 open-label, randomized study testing INT230-6 as monotherapy compared to the standard of care ("SOC") drugs in second and third line treatment for certain soft tissue sarcoma subtypes. The INVINCIBLE-3 Study is expected to enroll 333 patients and initiate sites in eight countries. This study has been authorized by the US FDA, Health Canada, the European Medicines Authority (for France, Germany, Italy, Poland and Spain), and Australia's Therapeutics Goods Administration. The primary endpoint in the INVINCIBLE-3 Study is overall survival.

In July 2024, the Company initiated and dosed its first patient in the INVINCIBLE-3 Study.  The trial is actively enrolling patients across the US, Canada, Europe and Australia. Up to 60 sarcoma-focused institutions are expected to participate from these regions. The Company has contracted 32 sites with 25 patients screened to date.  The Company expects to complete enrollment in the first half of 2026.

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 SOC treatment in patients with early-stage, operable triple-negative breast cancer ("TNBC") and SOC alone. The primary endpoint is the change in the pathological complete response rate for the combination compared to the SOC alone. The INVINCIBLE-4 Study is expected to enroll approximately 54 patients in Switzerland and France.

In October 2024, in collaboration with The Swiss Group for Cancer Research SAKK ("SAKK"), the Company initiated and dosed its first patient in Switzerland in the INVINCIBLE-4 Study. To date, the Company has activated eight sites in Switzerland and treated several patients. The Company expects to activate additional sites in Switzerland and France in the first half of 2025 and complete enrollment by the end of the first quarter of 2026. 

"In 2024, Intensity Therapeutics finalized both Phase 3 and Phase 2 protocols, engaged leading hospitals around the world, and obtained regulatory authorization to recruit patients in 9 countries to initiate treatment," stated Lewis H. Bender, Intensity Founder, President, and CEO. "Our programs were again selected for presentation at major sarcoma and breast cancer societies. Many of the best sarcoma treatment centers from the US, Canada, Europe and Australia are either participating now or in contract discussions.  For our breast cancer trial, our partners at SAKK have recruited interest by the leading hospitals in Switzerland and France to participate. Physicians are screening patients at an increasing rate. We believe in the potential for our drug to have a positive impact on the lives of metastatic sarcoma and presurgical breast cancer patients around the world, who so desperately need improved alternatives to current therapies." 

2024 Year End Financial Results

Research and development expenses were $10.5 million for the year ended December 31, 2024, compared to $4.8 million for the year ended December 31, 2023. The increase was primarily due to an increase of $5.6 million in the INVINCIBLE-3 Study in 2024, in which we enrolled our first patient in the third quarter of 2024, and to a lesser extent, an increase of $0.5 million in the INVINCIBLE-4 Study, in which we enrolled and dosed our first patient in the fourth quarter of 2024.  These increases were partially offset by a decrease of $1.1 million in our IT-01 Study due to the completion of enrollment in this study in mid-2022 and the completion of study-related costs in 2023.  Research and development also increased due to higher salary, benefits, and stock-based compensation.

General and administrative expenses were $6.1 million for the year ended December 31, 2024, compared to $3.5 million for the year ended December 31, 2023. The increase was primarily due to increased expenses related to salary, benefits and stock-based compensation, higher legal and consulting fees, and higher directors and officers insurance.

Overall, net loss was $16.3 million for the year ended December 31, 2024, compared to a net loss of $10.5 million for the year ended December 31, 2023.

As of December 31, 2024, cash and cash equivalents totaled $2.6 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 is comprised of two proven, potent anti-cancer agents, cisplatin and vinblastine, and a penetration enhancer molecule (SHAO) that helps disperse potent cytotoxic drugs throughout tumors for diffusion 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 in collaboration with The Swiss Group for Clinical Cancer Research SAKK (the "INVINCIBLE-4 Study") (NCT06358573) 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.
