Intensity Therapeutics’ Journey: From Inception to the Forefront of Cancer Research
Intensity Therapeutics, Inc. is a late-stage clinical biotechnology company that is pioneering the development of proprietary, novel immune-based intratumoral cancer therapies. The company’s mission is to revolutionize the treatment of solid tumors by directly targeting the tumor microenvironment and harnessing the power of the immune system to eradicate cancer.
Intensity Therapeutics was incorporated in Delaware in December 2012 with the goal of developing a new approach to treating cancer by directly injecting tumors with a unique product created from its DfuseRx SM discovery platform. The company’s lead product candidate, INT230-6, is primarily comprised of three components – two proven anti-cancer cytotoxic agents and an amphiphilic molecule that enables the cytotoxic agents to disperse through and penetrate a tumor. This innovative approach was designed to address the shortcomings of traditional cancer treatments, particularly the challenges in delivering effective therapies to solid tumors characterized by a dense, lipophilic, and high-pressure microenvironment.
In 2017, Intensity initiated its first clinical trial, a Phase 1/2 dose escalation study called IT-1, using INT230-6 in the United States and Canada. The study tested the safety and efficacy of INT230-6 in patients with refractory or metastatic cancers and enrolled 110 patients across three arms – INT230-6 monotherapy, INT230-6 in combination with Merck’s Keytruda, and INT230-6 in combination with BMS’s Yervoy. Intensity completed enrollment of IT-1 in June 2022 and finalized the clinical study report in September 2023. The results from this study demonstrated a favorable safety profile and evidence of anti-tumor activity, including an increase in T-cell activation.
Building on these promising findings, Intensity Therapeutics advanced INT230-6 into later-stage clinical trials. In 2021, the company initiated the INVINCIBLE-2 study, a randomized Phase 2 trial that evaluated INT230-6 as a monotherapy treatment in early-stage breast cancer patients not suitable for presurgical chemotherapy. The study enrolled 91 subjects and the database was locked in November 2023. Data from this study demonstrated that INT230-6 had a favorable safety profile and was able to achieve a high degree of tumor necrosis in the period from diagnosis to surgery, with some patients experiencing greater than 95% necrosis. Additionally, the data showed an increase in certain types of immune cells, such as CD4 and NK T-cells, both within the tumor and in the blood. Intensity finalized the clinical study report for the INVINCIBLE-2 Study in July 2024.
More recently, in July 2024, Intensity Therapeutics initiated the INVINCIBLE-3 study, a pivotal Phase 3 open-label, randomized trial testing INT230-6 as monotherapy compared to the standard of care drugs in second and third-line treatment for certain soft tissue sarcoma subtypes. This global study is expected to enroll 333 patients and has received authorizations in the United States, Canada, Europe, and Australia. The company plans to initiate sites in eight countries for this study.
In September 2024, Intensity received authorization to initiate the INVINCIBLE-4 study, a Phase 2 randomized open-label, multicenter study in Switzerland and France. This study aims to analyze the clinical activity, safety, and tolerability of INT230-6 given before administration of the standard of care treatment in patients with early-stage, operable triple-negative breast cancer. The INVINCIBLE-4 study is expected to enroll approximately 54 patients.
Intensity Therapeutics has also successfully developed Phase 3-quality analytical methods for the three components of INT230-6 and has manufactured a large-scale batch of the product candidate. In a meeting with the FDA in the fourth quarter of 2023, the company agreed on a chemical, manufacturing, and control (CMC) plan for Phase 3 and product registration, which, if successfully executed, should provide an acceptable CMC portion of a New Drug Application (NDA) for product approval and registration.
Financials and Liquidity
As a clinical-stage biotechnology company, Intensity Therapeutics has not yet generated any revenue from product sales, and the company has incurred significant operating losses since its inception. For the year ended December 31, 2023, the company reported a net loss of $10.5 million, with research and development expenses of $4.8 million and general and administrative expenses of $3.5 million.
For the most recent quarter ended September 30, 2024, Intensity Therapeutics reported no revenue, a net loss of $3.5 million, and negative operating cash flow of $4.0 million. Compared to the same quarter in the previous year, the net loss increased from $2.3 million, and operating cash flow decreased from negative $2.1 million. These decreases were primarily attributed to increased research and development and general and administrative expenses related to the initiation of the Phase 3 INVINCIBLE-3 study.
As of September 30, 2024, Intensity Therapeutics had $2.8 million in cash and cash equivalents. The company has financed its operations primarily through the sale of equity securities, including its initial public offering (IPO) in June 2023, which raised $22.4 million in gross proceeds. The company became public when its common stock began trading on the Nasdaq Capital Market under the symbol “INTS” following the IPO. In July 2024, the company also entered into an at-the-market (ATM) equity offering program, through which it has raised an additional $0.2 million in net proceeds as of September 30, 2024.
Intensity Therapeutics’ financial position as of September 30, 2024, shows a current ratio of 1.63 and a quick ratio of 1.63, indicating the company’s ability to meet its short-term obligations. The company has no debt, resulting in a debt-to-equity ratio of 0 as of December 31, 2023. However, Intensity Therapeutics has stated that it expects to incur significant expenses to complete the development of its product candidates, and there can be no assurance that the company will generate revenues or achieve profitability in the near future.
The company believes it has sufficient cash to fund its operations into the first quarter of 2025 but will need to raise additional capital through equity or debt financing, or other strategic transactions, to continue its research and development activities. Intensity Therapeutics’ ability to continue as a going concern is dependent on its ability to secure this additional funding.
Risks and Challenges: Navigating the Uncertain Landscape
As with any biotechnology company, Intensity Therapeutics faces a number of risks and challenges that could impact its future success. These include the inherent risks associated with the development of novel therapies, such as the potential for clinical trial failures, regulatory hurdles, and the ability to manufacture products at scale.
Additionally, the company’s reliance on a single lead product candidate, INT230-6, means that any setbacks or delays in the development of this program could have a significant impact on the company’s overall prospects. The highly competitive nature of the oncology market also presents a challenge, as Intensity Therapeutics must continue to differentiate its approach and demonstrate the unique advantages of its technology platform.
Furthermore, the company’s financial position and the need for additional capital raises concerns about its ability to sustain operations and execute its long-term strategic plans. Investors will closely monitor the company’s ability to secure funding and manage its cash resources effectively.
Outlook and Opportunities: Positioning for Continued Growth
