2025 Key Highlights and 2026 Outlook and Strategic Priorities

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 and SOC alone.
In September 2025, a pathological complete response was observed in the first patient evaluated in Cohort A, where each patient receives one or two doses of INT230-6 eight days apart, followed by the SOC. Some patients in Cohort A began to experience localized skin irritation, prompting a temporary pause in new patient enrollment. As a result, the protocol is being modified to administer one or two doses at lower volumes for each tumor size.

In December 2025, early observations data from the INVINCIBLE-4 Study were presented at the San Antonio Breast Cancer Symposium, showing favorable safety, with 50% fewer grade 3 or higher adverse events observed in the INT230-6 cohort compared to the standard of care neoadjuvant chemotherapy alone cohort. The INVINCIBLE-4 study was initiated in late 2024, and 14 patients have been treated, with 7 in each cohort.

The Company plans to file a protocol amendment with the regulatory agencies for this revision in dosing in the first quarter of 2026, and expects to reinitiate enrollment for the now 61-patient study in the first quarter of 2026, as seven additional patients will be added to cohort A.
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 specific soft tissue sarcoma subtypes.
In March 2025, the Company paused new site activations and patient enrollments due to funding constraints. Before this pause, the trial had enrolled 21 patients. The Company continues to treat patients enrolled in this study, maintain the database, conduct pharmacovigilance, and conduct other study-related activities in cooperation with its third-party contract research organizations at significantly reduced ongoing costs during this pause.

The Company has prioritized reinitiating patient enrollment and site activations during 2026 once sufficient funding is obtained.
Potential New Phase 3 Breast Cancer Study: The clinical study could be with INT230-6 plus standard of care, potentially also using biomarkers to assess the need for anthracyclines (doxorubicin) for the treatment of neoadjuvant Triple Negative Cancer (assuming sufficient funding has already been obtained for the reinitiation of the Phase 3, sarcoma INVINCIBLE-3 Study).
If safety and efficacy trends continue in the INVINCIBLE-4 Study, a Phase 3 clinical study design in the US and other countries using INT230-6 with the current standard of care may be initiated contingent on obtaining sufficient incremental funding.
Peer-Reviewed Publication in a Lancet journal: Validate Clinical Potential
In October 2025, Intensity announced publication of its Phase 1/2 clinical study evaluating INT230-6 in the Lancet Discovery Science journal, eBioMedicine (volume 121). The manuscript reported a 75% disease control rate and a median overall survival of 11.9 months in patients with advanced solid tumors, with a median overall survival of 21.3 months observed in a subset of sarcoma patients. At least 20% of patients receiving a dose greater than 40% of their total tumor burden had abscopal effects where uninjected tumors shrank. Exploratory analyses further demonstrated potential to improve disease control rates and overall survival, especially when treating higher percentages of tumor burden. There was also evidence of systemic immune engagement, reinforcing INT230-6’s differentiated mechanism of action.

During 2026, the Company will continue to pursue an aggressive peer-reviewed publications strategy for its completed metastatic and breast cancer studies.
Strengthened Balance Sheet, Extended Runway into the Second Quarter of 2027:
The Company raised over $20 million in gross proceeds during 2025 through two public offerings, one registered direct offering, and ATM issuances. These successful capital-raising efforts strengthened Intensity’s balance sheet and extended its current operating runway into the second quarter of 2027, providing flexibility to advance certain clinical programs without near-term financing pressure.

The Company plans to maintain a disciplined operating approach in 2026 and will seek to opportunistically raise additional capital during 2026 to reinitiate patient enrollment and site activations in the INVICIBLE-3 Study, and to potentially initiate a new Phase 3 Breast Cancer Study.
Business Development: Continuing to pursue discussions with potential pharmaceutical partners to potentially accelerate the development and commercialization of our new drug.
Intensity Therapeutics Founder, President, and CEO Lewis H. Bender stated, "We enter our next phase of development with a clinically validated scientific foundation and a capital position that supports disciplined execution. A peer-reviewed publication in eBioMedicine, a Lancet Discovery Science journal, reinforced the clinical potential of INT230-6. At the same time, our successful capital raising efforts provided the resources to advance our programs well into 2027. Our focus remains on generating high-quality clinical data, additional peer-review publications, advancing regulatory engagement, and allocating capital with intention as we progress INT230-6 across multiple development pathways, in an attempt to build long-term shareholder value through consistent execution."

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 non-covalently conjugates to the two payload drugs, facilitating the dispersion of potent cytotoxic drugs throughout tumors and 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.

Head-to-Head Real-World Data: Cadonilimab Outperforms PD-1 Inhibitors in First-Line PD-L1-Low Gastric Cancer

On January 13, 2026 Akeso, Inc. (9926.HK) reported the presentation of a real-world study at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium (ASCO GI), comparing cadonilimab plus chemotherapy against a PD-1 inhibitor plus chemotherapy for the first-line (1L) treatment for advanced gastric (G) or gastroesophageal junction (GEJ) cancer with PD-L1 CPS <5 (a propensity-matched, retrospective cohort study).

The study results showed that the cadonilimab regimen, compared to the PD-1 monoclonal antibody regimen, significantly prolonged patients’ overall survival (OS) and progression-free survival (PFS). Both OS (HR=0.49, P=0.025) and PFS (HR=0.43, P=0.006) demonstrated statistically significant improvements. The full study has been accepted for publication in the Journal of Gastrointestinal Oncology.

These real-world findings are highly consistent with the "all-comer benefit" profile previously observed for cadonilimab in the Phase III registrational trial COMPASSION-15. This real-world, head-to-head comparison further underscores cadonilimab’s potential to elevate the standard of cancer immunotherapy and address clinical challenges unresolved by single-target PD-1 inhibitors. Based on the data from the pivotal Phase III COMPASSION-15 study, cadonilimab received approval in China in September 2024 for the first-line treatment of advanced gastric cancer across all patient subgroups and this indication was added to cadonilimab’s list of covered indication under National Reimbursement Drug List (NRDL), effective 2026.

Anti-PD-1 antibodies combined with chemotherapy is the international standard of care for advanced gastric cancer. However, its efficacy is significantly limited in patients with PD-L1-low (CPS < 5) or negative (CPS < 1) expression, where these patients constitute nearly half of all advanced gastric cancer cases. As a result, the U.S. Food and Drug Administration (FDA) restricted all approved first-line PD-1 inhibitors for advanced gastric cancer to only PD-L1-positive patients in 2024. This aligns with recommendations from leading guidelines, such as those of the National Comprehensive Cancer Network (NCCN) and the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper), which prioritize PD-1-based regimens for patients with PD-L1 CPS ≥5. Consequently, PD-L1-low or -negative advanced gastric cancer remains a major unmet clinical need globally due to thelack of effective immunotherapy options. A recent real-world study provides new evidence addressing this challenge.

In this retrospective analysis, patients with PD-L1-low (CPS < 5) advanced G/GEJ cancer received first-line therapy with either cadonilimab plus chemotherapy or a PD-1 inhibitor plus chemotherapy. With a median follow-up of 11.0 months as of February 28, 2025, the results showed that the cadonilimab-based regimen achieved statistically significant and clinically meaningful improvements in both PFS and OS compared to the PD-1 inhibitor-based regimen.

Some Key Findings from the Study published at GI-ASCO:

Significant PFS and OS Improvement: Among PD-L1-low patients, the cadonilimab group achieved a median OS of 14.3 months, significantly longer than the 10.3 months observed in the PD-1 inhibitor group (OS HR=0.49, p=0.025), representing a 51% reduction in the risk of death. The median PFS was also extended to 9.3 months compared to 5.8 months in the control group (PFS HR=0.43, p=0.006), corresponding to a 57% reduction in the risk of disease progression or death.
Higher Objective Response Rate (ORR): The objective response rate was superior in the cadonilimab group compared to the PD-1 inhibitor group (73.3% vs. 57.1%) for PD-L1-low patients.
Manageable Safety and Good Tolerability: The incidence of any-grade adverse events was comparable between the two groups, and no statistically significant difference observed in the rate of grade 3-4 adverse events between the two groups.
Akeso is actively advancing several prospective head-to-head Phase III registration studies with cadonilimab, aiming to elevate current standard immunotherapies. Notably, the international multi-center Phase III registration study COMPASSION-37, evaluating cadonilimab plus chemotherapy versus the PD-1 inhibitor nivolumab plus chemotherapy for first-line treatment of advanced gastric cancer, received approval from the U.S. FDA to initiate at the end of 2025. This milestone marks a new phase in the global development of cadonilimab.

TROPION-Lung17 TROP2 Biomarker Directed Phase 3 Trial of DATROWAY® Initiated in Patients with Previously Treated Advanced Nonsquamous Non-Small Cell Lung Cancer

On January 13, 2026 Daiichi Sankyo reported the first patient has been dosed in the TROPIONLung17 phase 3 trial evaluating DATROWAY (datopotamab deruxtecan) compared to docetaxel in patients with TROP2 NMR positive locally advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC) without actionable genomic alterations previously treated with immunotherapy and platinum-based chemotherapy.

DATROWAY is a specifically engineered TROP2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN).

The current standard first-line treatment for advanced NSCLC without actionable genomic alterations is immunotherapy with or without platinum-based chemotherapy. 1 However, most patients will eventually experience disease progression and traditional chemotherapy remains the current standard of care in the second-line and beyond settings. 2,3,4,5 While TROP2 is a protein broadly expressed on the surface and inside of NSCLC cells, there is no established predictive biomarker that can identify patients who may benefit from a TROP2 directed antibody drug conjugate. 6,7 TROPION-Lung17 is the first phase 3 clinical trial to prospectively enroll patients with tumors that test positively for TROP2 NMR, a biomarker measured using Quantitative Continuous Scoring (QCS), which is AstraZeneca’s computational pathology platform.

"We initiated TROPION-Lung17 to further evaluate DATROWAY in this patient population, building on results from retrospective analyses of several clinical trials, including TROPION-Lung01, which showed a correlation between TROP2 NMR positivity and outcomes for patients with lung cancer," said Abderrahmane Laadem, MD, Head, Late-Stage Oncology Clinical Development, Daiichi Sankyo.

"TROPION-Lung17 is the first phase 3 trial to prospectively enroll patients using a TROP2 biomarker to determine whether DATROWAY can improve survival compared to current standard of care chemotherapy."

"TROPION-Lung17 aspires to bring a precision medicine approach to patients with advanced lung cancer in the second-line setting, where traditional chemotherapy remains the standard of care," said Leora Horn, MD, MSC, FRCPC, Senior Vice President, Late Development Oncology, AstraZeneca. "Research has shown DATROWAY has the potential to improve outcomes in this setting, and we are confident the TROP2 NMR biomarker and its investigational AI-powered companion diagnostic – previously granted a Breakthrough Device Designation in the U.S. – can help us bring this medicine to the patients most likely to benefit."

TROPION-Lung17 is the ninth phase 3 trial evaluating DATROWAY in NSCLC. Ongoing trials in advanced NSCLC include four phase 3 trials in the first-line metastatic setting evaluating DATROWAY in combination with immunotherapy in tumors without actionable genomic alterations (AVANZAR, TROPION-Lung07, TROPION-Lung08 and TROPION-Lung10) and one phase 3 trial of DATROWAY in combination with osimertinib, AstraZeneca’s EGFR tyrosine kinase inhibitor (TKI), (TROPION-Lung14) in EGFR-mutated NSCLC. Additional later-line phase 3 trials include evaluating DATROWAY with or without osimertinib (TROPION-Lung15) and DATROWAY alone (TROPION-Lung17).

About TROPION-Lung17

TROPION-Lung17 is a global, multicenter, randomized, open-label, phase 3 trial evaluating the efficacy and safety of DATROWAY (6 mg/kg) versus docetaxel in patients with TROP2 NMR positive locally advanced or metastatic nonsquamous NSCLC without actionable genomic alterations previously treated with PD-1/PDL1 inhibitor therapy and platinum-based chemotherapy. All patients will undergo prospective and central tumor testing for TROP2 NMR using the investigational VENTANA TROP2 (EPR20043) RxDx Device (comprised of the companion diagnostic assay and computational pathology algorithm) and those with TROP2 NMR positive tumors will be randomized in a 1:1 ratio to receive either DATROWAY or docetaxel.

The dual primary endpoints of TROPION-Lung17 are progression-free survival as assessed by blinded independent central review and overall survival. Key secondary endpoints include overall response rate, duration of response and safety.

TROPION-Lung17 will enroll approximately 400 patients across multiple sites in Asia, Europe and North America. For more information visit ClinicalTrials.gov.

About TROP2 NMR

TROP2 is a protein broadly expressed in NSCLC tumors.6,7 TROP2 expression on the surface of tumor cells, as measurable with conventional pathology methods, has not been predictive of patient responses to TROP2 directed therapies.8,9 Normalized membrane ratio (NMR) refers to the QCS enabled measure of a tumor cell’s surface TROP2 expression, relative to its surface and cytoplasm TROP2 expression. NSCLC is considered TROP2 NMR positive if at least 75% of tumor cells have a greater proportion of TROP2 in the cytoplasm. TROP2 NMR is being developed to identify patients with NSCLC most likely to benefit from treatment with DATROWAY

Exploratory analyses of the TROPION-Lung01 phase 3, TROPION-Lung02 phase 2 and TROPIONPanTumor02 phase 2 trials have shown a correlation between TROP2 NMR positivity and improved clinical outcomes in patients with NSCLC treated with DATROWAY

Daiichi Sankyo and AstraZeneca are collaborating with Roche Tissue Diagnostics to co-develop and commercialize the VENTANA TROP2 (EPR20043) RxDx Device as a novel AI-powered companion diagnostic for DATROWAY in lung cancer. The device was granted Breakthrough Device Designation by the U.S. Food and Drug Administration. In addition to TROPION-Lung17, it is being used to analyze tissue samples in the TROPION-Lung10 and AVANZAR phase 3 trials.

About Non-Small Cell Lung Cancer

Lung cancer is the most common cancer globally and is the leading cause of cancer-related death in both men and women.10 More than 2.48 million lung cancer cases were diagnosed in 2022, with 1.8 million deaths globally. NSCLC is the most common type of lung cancer, accounting for approximately 85% of cases.

For patients with advanced NSCLC without actionable genomic alterations, immunotherapy with or without platinum-based chemotherapy is the standard first-line treatment.1 While these medicines have improved outcomes in the first-line metastatic setting, most patients experience disease progression and traditional chemotherapy remains the standard of care in the second-line and beyond setting.

About DATROWAY

DATROWAY (datopotamab deruxtecan; datopotamab deruxtecan-dlnk in the U.S. only) is a TROP2 directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, DATROWAY is one of six DXd ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programs in AstraZeneca’s ADC scientific platform. DATROWAY is comprised of a humanized anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

DATROWAY (6 mg/kg) is approved in more than 40 countries/regions worldwide for the treatment of adult patients with unresectable or metastatic HR positive, HER2 negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease based on the results from the TROPION-Breast01 trial.

DATROWAY (6 mg/kg) is approved in Russia and the U.S. for the treatment of adult patients with locally advanced or metastatic EGFR-mutated NSCLC who have received prior EGFR-directed therapy and platinum-based chemotherapy based on the results from the TROPION-Lung05 and TROPION-Lung01 trials. Continued approval for this indication in the U.S. may be contingent upon verification and description of clinical benefit in the confirmatory trial.
