On February 23, 2021, NeuroRx announced that its Phase 2b/3 trial of ZYESAMI™ (aviptadil) for the treatment of patients with respiratory failure due to critical COVID-19, which was performed in collaboration with Relief Therapeutics Holdings, AG, has demonstrated 10-day accelerated recovery from respiratory failure in critically ill patients with COVID-19 treated with high flow nasal oxygen at the day 28 interim endpoint, and that NeuroRx intends to file for Emergency Use Authorization if positive results continue to be demonstrated at the day 60 endpoint in line with new guidance from the Food and Drug Administration. The press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.
The information set forth under this Item 7.01 is intended to be furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (“Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (“Securities Act”) or the Exchange Act, except as expressly set forth by specific reference in such filing.
Cautionary Note Regarding Forward Looking Statements
This Current Report on Form 8-K and the exhibits filed or furnished herewith include “forward-looking statements” within the meaning of the federal securities laws with respect to the proposed transaction between NeuroRx and BRPA, including statements regarding the drugs under development by NeuroRx. Actual results may differ from BRPA’s and NeuroRx’s expectations and consequently, you should not rely on these forward-looking statements as predictions of future events. These forward-looking statements generally are identified by the words “aspire,” “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” ���plan,” “may,” “will,” “will be,” “will continue,” “will likely result,” “could,” “should,” “believe(s),” “predicts,” “potential,” “continue,” “future,” “opportunity,” “strategy,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside BRPA’s and NeuroRx’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the approvals, timing, and ability to complete the proposed business combination, which may adversely affect the trading price of BRPA’s securities; (2) BRPA’s ability to remain listed on the Nasdaq Capital Market prior to the closing of the proposed business combination; (3) the combined company’s continued listing on the Nasdaq Capital Market after closing of the proposed business combination; (4) the benefits of the proposed business combination, including future financial and operating results of the combined company; (5) the inherent uncertainty associated with the FDA approval process; (6) the risk that the proposed transaction disrupts current plans and operations of NeuroRx as a result of the announcement and consummation of the transaction described therein and herein; (7) costs related to the proposed business combination; (8) changes in applicable laws or regulations; (9) the possibility that the combined company may be adversely affected by other economic, business, and/or competitive factors; (10) the impact of COVID-19 or other adverse public health developments; and (11) other risks and uncertainties that are detailed in the proxy statement/consent solicitation statement/prospectus and registration statement filed on Form S-4 with the Securities and Exchange Commission (“SEC”) and as indicated from time to time in BRPA’s filings with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements.
