The I-SPY COVID Trial is a Phase II adaptive platform trial that is testing agents that show promise for reducing the risk of death from and severity of illness for people who become critically ill after contracting COVID-19. The purpose of the trial is to rapidly screen multiple agents to find those with the best chance of effectively improving outcomes for those critically ill. The I-SPY COVID Trial now includes 18 sites as well as leaders in pulmonary and critical care centers from around the country who are working to identify and test new agents to improve patient outcomes.
The sponsor halted testing of Aerpio’s razuprotafib in the I-SPY COVID Trial because it was challenging to administer in the setting of COVID-19, with 30% of patients discontinuing the agent due to disease-related hypotension, including protocol-mandated stopping rules. There was no indication that razuprotafib caused the hypotension that led to clinical decline in systolic blood pressure. However, at the conclusion of two safety lead-in cohorts, it was determined there was a small but not clinically significant decline in systolic blood pressure and mean arterial blood pressure by approximately 4–5 mm Hg; there was no significant difference between the 10 mg and 20 mg dose in blood pressure decline. In addition, there was little if any blood pressure reduction in patients with pre-dose blood pressure readings of less than 100 mm Hg, even when on vasopressors, and there was no evidence that razuprotafib reduced the efficacy of vasopressors.
Because blood pressure monitoring with additional scrutiny is challenging in the setting of a surge in ICU admissions from COVID-19, the Data Monitoring Committee recommended that razuprotafib not be advanced after the second safety lead-in. This agent could be revisited in the setting of acute respiratory distress syndrome (ARDS) absent pandemic COVID-19.
“We are hopeful that razuprotafib can be tested in the future in classical non-COVID-19 ARDS patients as it has a strong rationale for potential efficacy for reducing lung injury in this population,” continued Dr.
“We were pleased with the overall tolerability of razuprotafib in these patients with critical COVID-19, including those in shock and on vasopressors. The modest reduction in blood pressure noted in this trial is attributed to the production of nitric oxide by endothelial cells downstream of Tie2 activation, which is considered an important component of the vascular stabilizing effects of razuprotafib,” said Dr.

Forward Looking Statements
This press release contains forward-looking statements. Statements in this press release that are not purely historical are forward-looking statements. Such forward-looking statements include, among other things, the Company’s strategic alternatives review process and the potential transactions that may be identified and explored as a result of that process, the Company’s product candidates, including razuprotafib, ARP-1536 and the bispecific antibody asset, the clinical development plan therefor, and the therapeutic potential thereof, the Company’s plans and expectations with respect to razuprotafib and the development therefor and therapeutic potential thereof in addressing COVID-19 and ARDS related thereto and the intended benefits from the Company’s collaboration with Gossamer Bio for GB004, including the continued development of GB004 and the milestone and royalty payments related to the collaboration. Actual results could differ from those projected in any forward-looking statements due to several risk factors. Such factors include, among others, the ability to identify and consummate strategic alternatives that yield additional value for shareholders; the timing, benefits and outcome of the Company's strategic alternatives review process, including the determination of whether or not to pursue or consummate any strategic alternative; the structure, terms and specific risks and uncertainties associated with any potential strategic transaction; potential disruptions in our business and the stock price as a result of our exploration, review and pursuit of strategic alternatives or the public announcement thereof and any decision or transaction resulting from such review; the continued development of GB004 and maintaining and deriving the intended benefits of the Company’s collaboration with Gossamer Bio; ability to continue to develop razuprotafib or other product candidates, including in indications related to COVID-19; our review and evaluation of strategic plans for our razuprotafib glaucoma program; the inherent uncertainties associated with the drug development process, including uncertainties in regulatory interactions, the design of planned or future clinical trials, commencing clinical trials and enrollment of patients in clinical trials; obtaining any necessary regulatory clearances in order to commence and conduct planned or future clinical trials; the impact of the ongoing COVID-19 pandemic on the Company’s business operations, including research and development efforts and the ability of the Company to commence, conduct and complete its planned clinical activities; and competition in the industry in which the Company operates and overall market conditions; and the additional factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2019, as updated by our subsequent Quarterly Reports on Form 10-Q and our other subsequent filings with the SEC.
