Updated Phase 1 NBTXR3 plus anti-PD-1 safety and efficacy data in recurrent and/or metastatic advanced cancers from Study 1100 to be presented at SITC 2022 on November 10^th
Bolstered NBTXR3 strategic development capability with the appointment of twelve global medical experts to the Nanobiotix Scientific Advisory Board
€53.5 million in cash and cash equivalents extends cash runway into Q1 2024

PARIS and CAMBRIDGE, Mass., Nov. 09, 2022 (GLOBE NEWSWIRE) -- NANOBIOTIX (NASDAQ:NBTX), a late-clinical stage biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer, today provided an update on operational progress and announced operational progress and cash position (unaudited) for the third quarter of 2022.

"This quarter saw us continue our prioritized focus on the advancement of NBTXR3 both as a single agent activated by radiotherapy and as a combination therapy with anti-PD-1 for patients with locally advanced head and cancer and recurrent and/or metastatic head and neck cancer, respectively," said Laurent Levy, co-founder of Nanobiotix and chairman of the executive board. "We believe that the data our clinical development program has produced to date supports the potential of NBTXR3 to improve therapeutic outcomes for patients in need of local control, systemic control, or both. We are eager to share additional Phase 1 data from Study 1100 at the annual SITC congress. In our view, these new data further strengthen our confidence, particularly in the immunostimulatory potential of NBTXR3, and add to our anticipation for the submission of our second registrational Phase 3 protocol to the US FDA for the evaluation of NBTXR3 plus anti-PD-1 in patients with recurrent and/or metastatic head and neck cancer expected in the first quarter of 2023."

Third Quarter Financial Updates

Nanobiotix reported cash and cash equivalents totaling €53.5 million as of September 30, 2022, compared to €83.9 million as of December 31, 2021.

In October 2022 Nanobiotix executed a final agreement with the European Investment Bank ("EIB") to re-align approximately €30.7 million in outstanding debt obligations with the Company's expected development and commercialization timelines. The cash and cash equivalents as of September 30, 2022, combined with the executed EIB debt restructuring and existing equity line, is expected to fund development programs into Q1 2024.
