Antibe Therapeutics Reports 2022 Year-End Results and Business Highlights

– Phase II acute pain program to initiate in early calendar Q4 2022

– Ended year with $55 million in cash and equivalents, providing over two years of runway

TORONTO–(BUSINESS WIRE)–$ATBPF–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 year ended March 31, 2022.

“Since its launch last fall, we’ve been encouraged by the results of otenaproxesul’s acute pain program, and it remains very much on track,” commented Dan Legault, Antibe’s CEO. “Our data suggest that the drug can deliver the onset of action and pain relief required for commercial success in acute pain indications – an exciting prospect in a massive market that’s seen minimal innovation over the last 20 years. To further de-risk the dose selection for the planned bunionectomy trial, we’ve added a short molar extraction study to the Phase II program – with no impact on cashflow. With a balance sheet that funds us well into 2024, we’re continuing to focus our efforts and expenditures on creating value for our shareholders.”

Business Highlights

The following covers fiscal Q4 2022 and subsequent events:

Launched otenaproxesul’s clinical program for post-operative pain

• Completed two pharmacokinetic/pharmacodynamic (“PK/PD”) studies; loading dose study suggests viable onset of action for acute pain relief
• Augmented plan replaces remaining healthy volunteer PK/PD studies with Phase II molar (wisdom tooth) extraction study to obtain more informative data in post-operative patients
• Phase II molar extraction study slated for initiation in early calendar Q4 2022 with top-line results expected within three months – to be followed by Phase II bunionectomy (foot bone surgery) study
• Ongoing investigation of alternative treatment regimens as a potential path forward for chronic indications

Other drugs advancing

• Evaluating two promising molecules to select lead candidate for inflammatory bowel disease program
• Filed patent for specialized pain indication for ATB-352, with potential for IP protection to extend into the 2040s

Corporate and governance
