Nanobiotix S.A. develops nanotechnology-based therapeutic platforms for cancer and other major diseases as a late-stage clinical biotechnology company. Its news commonly centers on JNJ-1900 (NBTXR3), a hafnium oxide nanoparticle radioenhancer administered by intratumoral injection and activated by radiotherapy, including head and neck cancer and lung cancer development updates, clinical data presentations, and regulatory communications.
Company updates also cover the Nanoprimer platform for bioavailability and biodistribution, preclinical work with lipid nanoparticle-delivered therapies, collaborations with Johnson & Johnson, Janssen and MD Anderson, periodic operating and financial results, and recurring disclosures of share capital and voting rights for its Euronext Paris and Nasdaq-listed securities.
Nanobiotix (NBTX) appointed Arnd Christ chief financial officer and a member of its executive board, effective October 1, 2026. He succeeds Bart Van Rhijn, who will step down as chief financial & business officer and executive board member after five years of service.
Christ has spent more than 25 years as chief financial officer of public and private biotechnology companies in Europe and the United States. Most recently, he served as chief financial officer of Immatics from October 2020 until September 2025. His previous CFO roles included InflaRx, MediGene, NovImmune and Probiodrug, and he also served on Immunocore’s supervisory board. His transaction experience includes initial public offerings, licensing deals and fundraising for private and publicly listed biotechnology companies.
Nanobiotix (NBTX) reported first-half 2026 results, including a €34.3 million net loss, and updated its lung cancer studies.
Revenue and other income fell to €5.6 million from €26.6 million a year earlier; the 2025 figure included €21.2 million in one-off, non-cash revenue. The loss widened from €5.4 million. Cash was €110.9 million at June 30, up from €52.8 million at year-end 2025. An approximately €86 million offering closed in May. The company expects its cash to fund operations into 2029.
In a Phase 1 lung cancer study, all 24 patients completed treatment; one-year locoregional control was 79%, with no dose-limiting toxicities. In the Phase 2 CONVERGE study, 6 of 7 patients had an investigator-reported response after the full regimen. The FDA cleared a Phase 3 NANORAY-312 protocol amendment that removed the planned interim analysis and reduced the events required for final analysis.
Nanobiotix (NBTX) reported its share capital and voting rights position as of August 31, 2026, in line with French market regulations.
The company had 50,941,528 shares outstanding on that date.

Nanobiotix is a late-stage clinical biotechnology company headquartered in Paris and listed on Euronext Paris and the Nasdaq Global Select Market.
Nanobiotix (NBTX) reported complete Phase 1 full-cohort results for radiotherapy-activated JNJ-1900 (NBTXR3) in 24 patients with inoperable, locoregionally recurrent non-small cell lung cancer eligible for re-irradiation.
All 24 patients completed JNJ-1900 plus re-irradiation with no dose-limiting toxicities and no Grade 3 or higher adverse events related to JNJ-1900 or the injection procedure. Grade 3 radiotherapy-related adverse events occurred in 33% of patients and Grade 5 radiotherapy-related events in 8%. The recommended Phase 2 dose was set at 33% of gross tumor volume.
At a median 12‑month follow-up (data cutoff August 2026), one-year locoregional control was 79%, one-year local progression-free survival was 61% (median 13.6 months), and one-year overall survival was 70% (median 14.8 months). Investigators concluded that JNJ-1900 may enable clinically meaningful local control at substantially lower re-irradiation doses, and additional enrollment in this trial is planned.
