About INT230-6

INT230-6, Intensity’s lead proprietary investigational product candidate, discovered using Intensity’s proprietary DfuseRxsm technology platform, is designed to cause tumor necrosis following direct intratumoral injection. INT230-6 contains two proven, potent anti-cancer agents, cisplatin and vinblastine, with a penetration enhancer molecule, SHAO, that helps disperse the potent cytotoxic drugs throughout tumors and enable diffusion into cancer cells. Importantly, each of the active drug agents remain in the tumor causing local disease control and tumor necrosis, leading to a favorable safety profile and the induction of an anti-cancer systemic immune response, resulting in shrinkage of uninjected tumors. Immunosuppression, often seen when dosing intravenous chemotherapy, is absent when treating with INT230-6.

Study IT-01 consists of a dose escalation and several Phase 2 expansion cohorts (NCT03058289) to evaluate INT230-6 in patients with various advanced solid tumors. In 2019, the Company signed a clinical collaboration agreement with Merck Sharpe & Dohme (Merck) to evaluate the combination of INT230-6 and KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 (programmed death receptor-1) therapy, in patients with advanced pancreatic, colon, squamous cell and bile duct malignancies, as part of study IT-01. In 2020, the Company executed a clinical collaboration agreement with Bristol-Myers Squibb Company to evaluate the combination of INT230-6 with Bristol-Myers Squibb’s anti-CTLA-4 antibody, Yervoy® (ipilimumab), in patients with advanced liver, breast and sarcoma cancers, as a separate cohort in study IT-01. In 2021, the Company executed agreements with the Ottawa Hospital Research Institute and the Ontario Institute of Cancer Research to study INT230-6 in a randomized controlled neoadjuvant phase 2 study in women with early stage breast cancer (the INVINCIBLE study) (NCT04781725). Over 200 patients have been enrolled in Intensity’s studies to date.

About Intensity Therapeutics

Intensity Therapeutics, Inc. is a clinical-stage biotechnology company pioneering a new immune-based approach to treat solid tumor cancers. Intensity leverages its DfuseRxsm technology platform to create new, proprietary drug formulations that, following direct injection, rapidly disperse throughout a tumor and diffuse therapeutic agents into cancer cells. Intensity’s product candidates have the potential to induce an adaptive systemic immune response that not only attacks the injected tumor, but also non-injected tumors. In addition to partnerships with Merck and Bristol-Myers Squibb, the Company executed a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute’s (NCI) Vaccine Branch in 2014.
