Welcome to our dedicated page for Nanobiotix news (Ticker: NBTX), a resource for investors and traders seeking the latest updates and insights on Nanobiotix stock.
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 (NASDAQ:NBTX) reported Part 1 data from the Johnson & Johnson-sponsored randomized Phase 2 CONVERGE trial of nanoradioenhancer JNJ-1900 (NBTXR3) in stage 3 inoperable NSCLC, presented at ESTRO 2026.
Early results in 7 patients showed ORR 85.7%, CRR 57.1%, and DCR 100% with concurrent chemoradiotherapy and durvalumab.
Nanobiotix (NASDAQ: NBTX) announced FDA acceptance of a protocol amendment to the pivotal NANORAY-312 global Phase 3 head and neck cancer study.
The amendment, submitted by Johnson & Johnson as global sponsor, removes the planned interim analysis, reduces the number of events for the final analysis, and moves the final analysis earlier. Nanobiotix says this could accelerate the global registration pathway for JNJ-1900 (NBTXR3) and anticipates the modified final analysis will read out in the timeframe of the originally planned interim analysis. Exact timing depends on when clinical events occur. Under the license agreement, Nanobiotix may be eligible for aggregate payments in the hundreds of millions tied to remaining development and regulatory milestones related to head and neck and lung cancer programs.
Nanobiotix (NASDAQ: NBTX) presented preclinical mouse data at AACR 2026 showing that pre-treatment with Nanoprimer before IV administration of LNP-delivered recombinant DNA (LNP-DNA) increased systemic bioavailability, reduced liver uptake and hepatic toxicity, and attenuated cGAS-STING inflammatory signaling versus LNP-DNA alone.
The findings support further evaluation of Nanoprimer sequenced with advanced extrahepatic LNP systems to potentially improve efficacy and safety.
