Antibe Therapeutics Reports 2021 Year-End Financial Results and Business Highlights

Antibe Therapeutics Inc. (TSX: ATE, OTCQX: ATBPF), a clinical stage company leveraging its unique hydrogen sulfide platform to develop safer medicines for pain and inflammation, today filed its financial and operating results for the fiscal year ended March 31, 2021.

"Since the beginning of the year we've made significant progress," commented Dan Legault, Antibe's CEO. "Our Phase III preparations for otenaproxesul achieved several milestones, including the clearance of its IND application with the FDA in the United States. While we continue to navigate COVID-19 restrictions, we're pleased to launch our required AME study next week which will also inform the dose selection for the Phase III adaptive trial. The successful amalgamation with Antibe Holdings provides a unified intellectual property base and strengthens our position with potential partners. On that front, our ability to execute deals was highlighted by the US$100 million partnership with Nuance Pharma in China, and we're now entering confidential discussions for the large markets."

Financial Results

Cash Position: As of March 31, 2021, the Company had an available cash balance totaling $72 million, compared to $6.2 million at ­­­­­­­March 31, 2020.

Revenue: For the year ended March 31, 2021, revenue totaled $9.7 million, a negligible increase compared to the fiscal 2020 period. All revenue was due to the Company's subsidiary, Citagenix; sales were adversely affected by the COVID-19 crisis in fiscal Q1 but recovered strongly in fiscal Q2 through Q4.

Net Loss: For the year ended March 31, 2021, net loss amounted to $26.3 million ($0.70 per share), compared to $19.3 million ($0.71 per share) for fiscal 2020.

Research and Development Expenses: Research and development expenses for the year increased to $13.4 million compared to $8.1 million in fiscal 2020. The increase was primarily due to higher development costs for the Phase IIB dose-ranging, efficacy study for otenaproxesul as well as required non-clinical studies.

General and Administrative Expenses: General and administrative expenses amounted to $7.2 million for the year compared to $5.2 million for fiscal 2020. The increase was primarily due to higher overall payroll, professional and consulting fees, office expenses and other costs.

Sales and Marketing Expenses: Selling and marketing expenses totaled $2.7 million for the year compared to $3.8 million in fiscal 2020. The decrease consisted of lower salaries and commissions, advertising and promotions costs and travel and entertainment costs.

With the divestiture of a Citagenix subsidiary (BMT Medizintechnik GmbH) during the year, the above-stated financial results reflect continuing operations. The Company's audited fiscal 2021 consolidated financial statements, MD&A and AIF will be available shortly on SEDAR.
