Intensity Therapeutics Reports First Quarter 2025 Financial Results and Provides Corporate Update

• Eight Swiss sites are activated in the INVINCIBLE-4 Study, and several patients have been treated
  
  
  
  
• European Medicines Agency Authorization to initiate INVINCIBLE-4-Study in France

SHELTON, Conn., May 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 first 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 ("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 recruiting patients in Switzerland and is expected to enroll 54 patients across Switzerland and France.

In April 2025, the Company and The Swiss Group for Clinical Cancer Research SAKK, a decentralized academic research institute that has been conducting clinical trials of cancer treatments in all major Swiss hospitals since 1965, announced that the European Medicines Agency has authorized the initiation of the INVINCIBLE-4 Study in France in collaboration with Unicancer. The Unicancer French breast intergroup (UCBG) is the French referent cooperative group in breast cancer. The French National Cancer Institute (INCa) accredited the group in 2013, thus acknowledging its academic excellence and operational capability. Since its creation, the group has conducted more than 40 national and international multicenter clinical trials, as well as various translational research projects. 

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 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 March 2025, the Company paused new site activations and patient enrollments due to funding constraints, and prioritized funding for the INVINCIBLE-4 Study. 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 its third-party contract research organizations to reduce ongoing costs during this pause.

April 2025 Public Offering: 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.

"The first quarter saw continued progress in our important programs despite high volatility in the markets and funding constraints," stated Lewis H. Bender, Intensity Founder, President, and CEO. "Several patients in our sarcoma study had their first follow-up scans, which showed high levels of necrosis in the injected tumors. Site contracting, site activation and patient enrollment were increasing nicely. However, due to cash needs, we made the necessary decision to pause the Phase 3 sarcoma enrollment and site activation until additional funding becomes available. We are working closely with our vendors and sites to treat those patients enrolled in INVINCIBLE-3, while maintaining the pharmacovigilance, site monitoring and the study database. Meanwhile, our partners SAKK and Unicancer will continue to work with the leading hospitals in Switzerland and France to seek patients for our breast cancer trial, INVINCIBLE-4. We believe in the potential for our drug to positively impact the lives of metastatic sarcoma and presurgical breast cancer patients worldwide. As cancer deaths increase, new and  improved alternatives to current therapies are needed now more than ever."  

First Quarter 2025 Financial Results

Research and development expenses were $2.2 million for the three months ended March 31, 2025, compared to $2.8 million for the same period in 2024. Clinical trial expenses increased marginally by $0.1 million due to the ongoing site initiations and patient enrollment of the INVINCIBLE-03 Study. Contract manufacturing costs declined by $0.2 million, as there were no manufacturing batches of INT230-6 in the first quarter of 2025. In addition, stock-based compensation was $0.4 million lower as no new equity grants were awarded in the first quarter of 2025.

General and administrative expenses were $1.2 million for the three months ended March 31, 2025, compared to $1.9 million for the same period in 2024. Legal, audit and other expenses decreased as a result of cost saving from the integration of new systems in the administrative areas.   In addition, stock-based compensation was $0.3 million lower as no new equity grants were awarded in the first quarter of 2025.

Overall, net loss was $3.3 million for the three months ended March 31, 2025, compared to a net loss of $4.6 million for the three months ended March 31, 2024.

As of March 31, 2025, cash and cash equivalents totaled $0.9 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.
