What Nanobiotix does

Nanobiotix is a late-stage clinical biotechnology company developing physics-based nanotherapeutics for oncology, headquartered in Paris, France with a U.S. subsidiary in Cambridge, MA, and dual-listed on Euronext Paris (NANO) and Nasdaq (NBTX). Its core asset is NBTXR3 (JNJ-1900 / Hensify), a first-in-class nanoradioenhancer composed of functionalized hafnium oxide nanoparticles administered by a one-time intratumoral injection prior to standard radiotherapy, designed to increase radiation energy deposition within tumor cells up to 9x without proportionally damaging healthy tissue and to prime an antitumor immune response through immunogenic cell death. NBTXR3 is being evaluated across 14 solid tumor indications including head and neck squamous cell carcinoma, non-small cell lung cancer, esophageal, pancreatic, liver, rectal, and soft tissue sarcoma, with registrational Phase 3 NANORAY-312 in head and neck cancer led by Johnson & Johnson's Janssen under a global licensing/co-development agreement amended in 2025. A second proprietary platform, Curadigm Nanoprimer, consists of lipid-based nanoparticles engineered to temporarily occupy liver clearance pathways and improve systemic bioavailability of co-administered IV therapies, with collaborations involving Sanofi, MIT, and Earli.

The company's revenue model is pre-commercial and concentrated almost entirely on the Janssen partnership, comprising licensing/milestone payments (up to ~$2.6 billion in potential milestones plus tiered double-digit royalties), supplemented by a 2025 royalty monetization with HealthCare Royalty Partners (up to $71M), a 2023 financing round anchored by Johnson & Johnson Innovation – JJDC, and a $100M oversubscribed global offering closed in May 2026 that extends cash runway into 2029. NBTXR3 holds CE Mark approval (2019) for locally advanced soft tissue sarcoma as Hensify in 27 European countries and FDA Fast Track designation for head and neck cancer (2019); the FDA-accepted NANORAY-312 protocol amendment eliminates a planned interim analysis and is intended to accelerate the registrational readout. Nanobiotix employs 101–250 people, was founded in 2003 by CEO Laurent Levy, and is governed by a French SA à directoire et conseil de surveillance structure.

Revenue model

1. Licensing and Milestone Payments: Global license agreement with Johnson & Johnson's Janssen provides approximately $2.6 billion in potential milestones and tiered double-digit royalties. Payments contingent on development, regulatory, and commercial milestones across multiple indications. The 2025 amended agreement significantly reduced Nanobiotix's financial burden while preserving potential milestone payments.
2. Royalty Monetization: Non-dilutive royalty financing deal valued at up to $71 million with Healthcare Royalty (HCRx), providing upfront funding in exchange for future royalty streams. Extended cash runway into early 2028.
3. Product Revenue (Future): Once regulatory approvals are obtained, revenue will be generated from product sales of NBTXR3/Hensify. FDA accepted protocol amendment for Phase 3 head and neck cancer study potentially enabling earlier revenue generation.
4. Curadigm Platform Collaborations: Revenue potential from external partnerships leveraging the Nanoprimer platform to overcome bioavailability challenges in RNA/DNA therapies, gene therapies, and oncolytic viruses. Company is pursuing both external partnerships and proprietary internal pipeline development.

Core offering

Nanobiotix develops and clinical-stage commercializes physics-based nanotherapeutic platforms for oncology. Its lead asset NBTXR3 is a first-in-class nanoradioenhancer of functionalized hafnium oxide nanoparticles administered via one-time intratumoral injection to enhance radiotherapy energy deposition in solid tumors, complemented by the Curadigm Nanoprimer Platform of lipid-based nanoparticles designed to temporarily block hepatic clearance and improve bioavailability of intravenously administered therapeutics.

Product overview

Nanobiotix is a late-stage clinical biotechnology company pioneering physics-based nanotherapeutics. The company's core product is NBTXR3 (also known as JNJ-1900 and branded as Hensify in Europe), a first-in-class nanoradioenhancer using hafnium oxide nanoparticles designed to enhance radiotherapy efficacy in solid tumors. NBTXR3 is administered via one-time intratumoral injection prior to standard radiotherapy and works by increasing radiation energy deposition within tumor cells up to 9 times compared to radiotherapy alone. The company also operates the Curadigm Nanoprimer Platform, a proprietary technology designed to overcome liver clearance barriers and improve bioavailability of intravenously administered therapies. The two platforms are distinct but complementary: NBTXR3 targets enhanced cancer cell destruction through physics-based radioenhancement, while the Nanoprimer addresses therapeutic delivery challenges across multiple drug classes including RNA/DNA therapies, gene therapies, and oncolytic viruses.
