In addition to substantial technology advancement, the Company continued to bolster its management team with the following appointments:
- On June 6, 2022, XORTX welcomed Anthony Giovinazzo to the Board of Directors and as Chair of the Board. Anthony Giovinazzo is an internationally recognized expert in intellectual property, drug development and commercialization, including numerous licensing agreements, with more than 25 years’ experience in Central Nervous System diseases. He was the Chief Executive Officer and Director of Cynapsus Therapeutics, a NASDAQ listed specialty pharmaceutical company that developed the first successful sublingual apomorphine thin film strip for Parkinson’s disease Mr. Giovinazzo was a co-inventor of the drug, built the leadership team, set the strategy, raised US $136 million including an over-subscribed IPO and NASDAQ listing. Ultimately negotiations with several pharmaceutical companies that resulted in a CAD $841 million, all cash acquisition, by Sunovion Pharmaceuticals (Dainippon Sumitomo Pharmaceuticals).
- On November 16, 2022, the Company appointed Stacy Evans, M.D., MBA as Chief Business Officer initiating a business development outreach program associated with the Company’s XRx-008 program, with the goal of identifying a global partner for Phase 3 development and commercialization. Stacy Evans, M.D., MBA, is an executive consultant with nearly 25 years of commercial development and business development experience, including 12 years at Pfizer where he led multiple transactions for Pfizer, including significant deal experience in the rare disease space.

In summary, activity during 2022 advances the Company’s intellectual property portfolio, characterizes the XORLOTM formulation pharmacokinetics for dose modeling and dose selection in individuals with kidney disease. The XRX-OXY-101 data gathered provides key understanding for communications with the FDA, EMA and Health Canada to advance the optimal design of XORTX’s registration trial for ADPKD. These communications continue to de-risk the XRx-008 program and drug candidate for treating ADPKD and sets up XORTX for more in-depth and meaningful partnering discussions in the near future.
Goals for 2023
In 2023, XORTX will be focused on advancing XORLOTM as part of the XRx-008 for ADPKD into a Phase 3 registration clinical trial, the submission of an Orphan Drug Designation (“ODD”), initiation of special protocol assessment discussions with the FDA and initiation of commercialization activities for XORLOTM as well as advancing research in other kidney disease applications. To achieve these objectives, XORTX’s action plan includes:
- Initiate XRX-OXY-301 Registration supporting “Accelerated Approval” of XORLOTM for individuals with ADPKD. This study is a Phase 3, Multi-Center, Double-Blind, Placebo Controlled, Randomized Withdrawal Design Study to Evaluate the Efficacy and Safety of a Novel Oxypurinol Formulation in Patients with Progressing Stage 2-4 ADPKD and Coexistent Hyperuricemia. This study will provide data to support a future “Accelerated Approval" new drug application (“NDA”) submissions to the FDA and EMA. This study is planned to start in the second half of 2023 and will enroll individuals with stage 2, 3 or 4 ADPKD accompanied by chronically high uric acid. The objective of this study is to evaluate the ability of XORLOTM to slow the expansion of total kidney volume over a 12-month treatment period.
- Complete Orphan Drug Designation. XORTX’s ODD application was filed in January 2023, with anticipated feedback from the FDA ODD office within 90 days and ODD status during the first half 2023. Acceptance of the XRx-008 program further de-risks this program regarding the use of XORLOTM as a treatment for ADPKD.
- Prepare and Communicate with the FDA and EMA regarding the XRX-OXY-302 Registration trial in ADPKD. XRX-OXY-302 is a Phase 3, Multi-Center, Double-Blind, Placebo Controlled, Randomized Withdrawal Design Study to Evaluate the Efficacy and Safety of a Novel Oxypurinol Formulation in Patients with Progressing Stage 2-4 ADPKD and Coexistent Hyperuricemia. with progressing stage 2, 3, or 4 kidney disease. The objective of this study is to evaluate the safety and effectiveness of XORLOTM for the XRx-008 program over a 24-month treatment period. The aim of the study is to characterize the ability of XOI to decrease the rate of decline of glomerular filtration rate. An estimated 300 patients will be enrolled. This study is planned to start in the second half of 2024, subject to Special Protocol Assessment negotiations with the FDA.
- Ongoing CMC Work. In parallel with the XRX-OXY-301 and XRX-OXY-302 studies, XORTX will be focus scale-up, validation and stability testing of clinical drug product supplies of XORLOTM under the Company’s granted IND, as well as future clinical and commercial supplies. All development will be performed according to current GMP methodology. This work will be ongoing throughout 2022 and 2023.
- Activities Related to Potential Commercial Launch. In preparation for a possible “Accelerated Approval" NDA filing in 2025 in the U.S. for XORLOTM for XRx-008, XORTX will conduct commercialization studies, including nephrologist, patient, payer interviews, to support in-depth analysis of pricing and/or reimbursement, as well as product brand name selection and filings, and plans for launch. This work will be ongoing from 2023 to 2025.
- Activities Related to European Registration. XORTX will continue to work with and seek out guidance from the EMA to facilitate the path to approval of XORLOTM in the European Union, including required clinical studies and reimbursement conditions. This work will be ongoing from 2023 through 2026, and will include future drug orphan status.
To achieve the above goals, XORTX will continue to pursue non-dilutive and dilutive funding and expand discussions to partner with a major pharma / biotech companies with a global reach. XORTX will also increase financial and healthcare conference participation to further strengthen and expand our investor base.
