Antibe Therapeutics Reports Q1 2023 Interim Financial and Operating Results

- Phase II acute pain program to initiate in September

- Ended quarter with $50 million in cash and equivalents, providing over two years of runway

Antibe Therapeutics Inc. (TSX: ATE, OTCQX: ATBPF), a clinical stage company leveraging its hydrogen sulfide platform to develop next-generation safer therapies that target inflammation, has filed its financial and operating results for the fiscal quarter ended June 30, 2022.

“We are really pleased with our progress,” commented Dan Legault, Antibe’s CEO. “The data we’ve collected supports otenaproxesul’s target profile as a GI-safe, non-opioid oral analgesic for acute pain – a multi-billion dollar market devoid of innovation and in great need of novel therapies. We’re particularly excited to launch the Phase II molar extraction study next month, enabling us to collect data in post-operative patients for the first time. The results of this study should allow us to identify the optimal dosing regimens for the larger Phase II bunionectomy trial next year.”

• Completed loading dose pharmacokinetic/pharmacodynamic (“PK/PD”) study in the quarter; results suggest viable onset of action for acute pain relief
