  • Investigators concluded that the encouraging oncologic outcomes coupled with a favorable safety profile warrant further evaluation in a randomized trial

  • 23 months median Overall Survival from date of diagnosis was observed in 22 patients with locally advanced or borderline resectable pancreatic cancer

  • US FDA approved protocol amendment to launch new cohort evaluating RT-activated NBTXR3 combined with standard-of-care concurrent chemotherapy and recruitment is ongoing

  • Full data from the completed dose escalation and dose expansion cohorts to be presented at a medical congress in 1H 2025

PARIS and CAMBRIDGE, Mass., Dec. 09, 2024 (GLOBE NEWSWIRE) -- NANOBIOTIX (Euronext: NANO –– NASDAQ: NBTX – the ‘‘Company’’), a late-clinical stage biotechnology company pioneering nanoparticle-based therapeutic approaches to expand treatment possibilities for patients with cancer and other major diseases, today 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”). The Phase 1 study is being conducted by The University of Texas MD Anderson Cancer Center (“MD Anderson”).

Patients with LAPC or BRPC often receive initial treatment with cytotoxic chemotherapy followed by RT +/- concurrent or maintenance chemotherapy.

This Phase 1 study was designed to evaluate the safety, feasibility, and early signs of efficacy of RT-activated NBTXR3 for patients with LAPC or BRPC after initial treatment with cytotoxic chemotherapy, in comparison to the historical data in patients who received RT +/- concurrent or maintenance chemotherapy after initial treatment with cytotoxic chemotherapy.

Investigators observed an mOS of 23 months from the date of diagnosis in 22 patients (20 with LAPC and 2 with BRPC) on the trial that compared favorably with outcomes at MD Anderson where the historical control for mOS in 144 patients treated at the same center was 19.2 months. Investigators concluded that RT-activated NBTXR3 was well tolerated by all patients and that the encouraging oncologic outcomes observed warrant further evaluation in a randomized trial.

Following these encouraging results from the study, MD Anderson submitted and received US FDA clearance for a new, additional study cohort evaluating the combination of NBTXR3 and standard-of-care concurrent chemoradiation. The new cohort has launched, and recruitment is ongoing.

“The results we have observed in this Phase 1 study give us confidence that NBTXR3 could have a significant impact for these patients,” said Louis Kayitalire, MD, Chief Medical Officer at Nanobiotix. “We look forward to the data from the new cohort and believe the combination of NBTXR3 and concurrent chemoradiation could produce even more favorable outcomes for patients with locally advanced or borderline resectable pancreatic cancer.”
