Announcement
NANOBIOTIX announced updated data from cohorts 1 and 2 of Study 1100, a multicenter Phase 1 dose escalation and expansion trial evaluating JNJ-1900 (NBTXR3) activated by radiation therapy ("RT") followed by anti-PD-1 immune checkpoint inhibitors (pembrolizumab or nivolumab; "ICIs") in patients with recurrent and/or metastatic head and neck squamous cell carcinoma ("R/M-HNSCC") that is naïve (cohort 1) or resistant (cohort 2) to prior anti-PD-1 therapy.
AI Summary
Nanobiotix shared updated Phase 1 results from cohorts 1 and 2 of Study 1100, which tests JNJ-1900 (NBTXR3) activated by radiation therapy (RT) followed by anti-PD-1 drugs pembrolizumab or nivolumab in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M-HNSCC) who are either naïve or resistant to prior anti-PD-1 treatment.
Treatment was well tolerated in 103 heavily pre-treated patients, with consistent injection feasibility at the recommended dose. Most side effects were low grade: 27 patients had any-grade events related to JNJ-1900 and 32 to the injection procedure. Only nine patients experienced grade 3 or higher events linked to the nanoparticle or injection.
Among evaluable patients naïve to anti-PD-1 therapy (n=41), disease control rate (DCR) per RECIST 1.1 was 63% and objective response rate (ORR) 37%, with median overall survival (mOS) of 15.5 months. In resistant patients (n=50), DCR was 74%, ORR 32%, and mOS 11.4 months. These encouraging safety and efficacy signals support further study in randomized trials.

Announcement
NANOBIOTIX announced new results focused on patients with primary cutaneous melanoma from the ongoing Phase 1 Study 1100 evaluating JNJ-1900 (NBTXR3) in combination with immune checkpoint inhibitors (pembrolizumab or nivolumab) for patients with advanced cancers.
AI Summary
NanoBiotix presented new Phase 1 Study 1100 results in patients with primary cutaneous melanoma whose cancer had progressed after multiple therapies, including anti-PD-1 drugs. Data were shared at the ImmunoRad conference in Paris on September 17, 2025.
In this trial, 21 patients received a one-time intratumoral injection of NBTXR3 (JNJ-1900) at the recommended Phase 2 dose (33% of gross tumor volume), followed by radiotherapy and pembrolizumab or nivolumab. Injection was feasible in all cases, and most treatment-related side effects were mild to moderate (grades 1–3), with only a few events linked directly to NBTXR3.
Among 19 evaluable patients, the objective response rate was 47.4% (9/19), including four complete and five partial responses. The disease control rate reached 78.9% overall and 100% in injected tumors. Median overall survival was 14.6 months. Deeper local responses often coincided with systemic tumor regression.
Investigators believe these encouraging safety and early efficacy signals support further randomized trials. NanoBiotix will host a conference call on September 18, 2025 to discuss these findings.

Announcement
NANOBIOTIX announced the presentation of full results from the completed dose escalation and dose expansion phases of a Phase 1 study evaluating JNJ-1900 (NBTXR3) in patients with locally advanced or borderline resectable pancreatic cancer.
AI Summary
NANOBIOTIX presented full Phase 1 study results of JNJ-1900 (NBTXR3) in patients with locally advanced or borderline resectable pancreatic cancer. The study, conducted by MD Anderson, showed that the treatment has a favorable safety profile and that the injection method is feasible. Among the 22 patients treated, the median overall survival was 23 months from diagnosis. Moreover, the median local progression-free survival reached 13.3 months shortly after completing radiation treatment.
Exploratory biomarker analyses revealed that increased circulating tumor mutational burden was associated with better local control and overall survival, while CA19-9 normalization—observed in 59% of patients—also correlated with longer survival. Based on these encouraging results, investigators believe that further evaluation in a randomized study is warranted, including an ongoing cohort that combines standard-of-care chemotherapy with radiotherapy-activated JNJ-1900.

Announcement
NANOBIOTIX announced the first data from the completed dose escalation part of a Phase 1 study sponsored by The University of Texas MD Anderson Cancer Center ("MD Anderson") evaluating radiotherapy-activated NBTXR3 (JNJ-1900)1 as a second or later line (2L+) therapy for patients with locally advanced non-small cell lung cancer ("NSCLC") amenable to re-irradiation.
AI Summary
NANOBIOTIX announced the first results from the completed dose escalation phase of a Phase 1 study sponsored by MD Anderson Cancer Center. The study evaluated the radiotherapy-activated NBTXR3 (JNJ-1900) as a second or later line treatment for patients with locally advanced non-small cell lung cancer (NSCLC) who are candidates for re-irradiation. In a group of 12 patients, the treatment showed a favorable safety profile with no dose-limiting toxicities and confirmed that intratumoral injections are feasible. Early survival data were promising, with a 12-month local progression-free survival rate of 64% (median of 18.6 months) and a 12-month overall survival rate of 83% (median of 30.2 months). Based on these encouraging findings, the recommended phase 2 dose was set at 33% of the gross tumor volume, and the study's expansion phase is now underway.

Announcement
NANOBIOTIX announced that the first patient has been dosed in the CONVERGE study, a Phase 2 randomized controlled clinical trial evaluating potential first-in-class radioenhancer JNJ-1900 (NBTXR3) for the treatment of patients with Stage 3 unresectable non-small cell lung cancer receiving standard of care chemoradiation followed by consolidation durvalumab (NCT06667908).
AI Summary
NANOBIOTIX announced that the first patient has been dosed in the CONVERGE study, a Phase 2 randomized controlled trial. This trial is testing the potential first-in-class radioenhancer JNJ-1900 (NBTXR3) for patients with Stage 3 unresectable non-small cell lung cancer. In this study, patients receive standard chemoradiation and then consolidation durvalumab, with the goal of enhancing the effects of radiotherapy. The treatment involves a one-time intratumoral injection of NBTXR3, which is activated during radiotherapy to increase tumor cell death and possibly stimulate a longer-term immune response.
The CONVERGE study is sponsored by Janssen Pharmaceutica NV, a Johnson & Johnson Company, under a global license agreement. This early dosing marks an important step in evaluating the radioenhancer’s ability to meet the significant unmet needs for better treatments in this challenging cancer population.

Announcement
NANOBIOTIX announced the completion of the dose escalation and dose expansion parts of a Phase 1 study evaluating radiotherapy("RT")-activated NBTXR3 (JNJ-1900) for patients with locally advanced pancreatic cancer ("LAPC") or borderline resectable pancreatic cancer ("BRPC").
AI Summary
NANOBIOTIX has completed the dose escalation and dose expansion stages of a Phase 1 study evaluating its radiotherapy-activated NBTXR3 (JNJ-1900) for patients with locally advanced or borderline resectable pancreatic cancer. In the trial at MD Anderson Cancer Center, 22 patients treated after initial chemotherapy showed a promising median overall survival of 23 months from diagnosis. This outcome compares favorably with historical results, suggesting that adding NBTXR3 to the treatment plan may enhance patient survival.
Following these encouraging results, the US FDA approved a protocol amendment to begin a new cohort study. This additional study will evaluate the combination of NBTXR3 with standard-of-care concurrent chemoradiation. Researchers plan to present the full data from the completed cohorts at a medical congress in the first half of 2025, highlighting the potential for improved treatment outcomes.
