- Phase III-enabling activities for otenaproxesul proceeding well; AME study begins next week

- Ended year with a strong $72 million cash position, providing over two years of runway and fully funding Phase III adaptive trial

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.”

Business Highlights

Otenaproxesul, lead product candidate entering Phase III trials for osteoarthritis pain

• Completed all Phase III-enabling animal long-range and reproductive toxicology studies required to commence the Phase III adaptive trial (10 studies in total)
• Cleared Investigational New Drug (“IND”) filing with U.S. FDA to allow human clinical trials in the United States – IND-opening single-dose study underway in 24 subjects
• Received approval to commence the required absorption, metabolism and excretion (“AME”) study in 90 subjects
• Retained senior clinical operations director, Dr. Ana Stegic, to support clinical trial management and execution
• Completed a strategic licensing deal with Nuance Pharma for the commercialization of otenaproxesul in the Greater China region, with milestone payments totaling US$100 million and a double-digit royalty
• Commenced partnering process for the large markets (United States, EU4, UK and Japan) led by a leading global transaction firm

New chemistry initiatives targeting candidates to expand and bolster pipeline

• Announced collaboration with Dalriada Drug Discovery to exploit hydrogen sulfide platform in new disease areas including inflammatory bowel disease
• Fortifying intellectual property position for existing pipeline

Fully funded for over two years with 100% ownership of underlying intellectual property

• Successfully raised $40 million in a bought deal public offering, providing over two years of cash runway and fully funding otenaproxesul’s Phase III adaptive efficacy trial
• Completed amalgamation with Antibe Holdings to unify the intellectual property ownership of the Company’s drugs and platform – eliminates significant royalty liability on future revenues

Upcoming Milestones

• Completion of single-dose IND-opening study – Q3 2021
• Completion of AME study – Q4 2021

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.
