Nanobiotix ( (NBTX) ) just unveiled an update.

On May 17, 2026, Nanobiotix reported that Johnson & Johnson presented Part 1 data from the CONVERGE randomized Phase 2 trial of its nanoradioenhancer JNJ-1900 (NBTXR3) in patients with stage 3 inoperable non-small cell lung cancer at the ESTRO 2026 meeting. Early results from seven patients showed that intratumoral or intranodal injection of JNJ-1900 combined with concurrent chemoradiotherapy and durvalumab was feasible and appeared safe, with an overall response rate of 85.7%, a complete response rate of 57.1%, a disease control rate of 100%, and no progressive disease observed.

These initial outcomes suggest deeper and potentially more durable responses than typically seen with current standard-of-care chemoradiation with or without durvalumab, where complete responses are usually below 5%. The data strengthen Nanobiotix’s strategic positioning around NBTXR3 as a potentially first-in-class, scalable radioenhancer across solid tumors, complementing its ongoing Phase 3 NANORAY-312 head and neck cancer program and its global co-development and commercialization alliance with Johnson & Johnson.

The most recent analyst rating on (NBTX) stock is a Buy with a $36.00 price target. To see the full list of analyst forecasts on Nanobiotix stock, see the NBTX Stock Forecast page.

**Spark’s Take on NBTX Stock**

According to Spark, TipRanks’ AI Analyst, NBTX is a Neutral.

The score is primarily constrained by weak financial fundamentals (ongoing losses, cash burn, and balance-sheet pressure including negative equity and higher leverage). Offsetting this are strong technical momentum (though extended) and a constructive earnings-call outlook emphasizing improved runway and multiple clinical catalysts, while valuation support is limited given negative earnings and no dividend.
