This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”), which are subject to the “safe harbor” created by those sections for such statements.

Examples of these statements include, but are not limited to, statements regarding:

● our estimates of future operating expenses and projections regarding how long our existing cash, cash equivalents and short-term investments will fund our anticipated operating expenses, capital expenditures and debt service obligations;

● whether and when our biologics license application (“BLA”) for narsoplimab in TA-TMA may be resubmitted to FDA, whether and when a marketing authorization application (“MAA”) may be submitted to the EMA for narsoplimab in any indication, and whether and when FDA, the EMA or any other regulatory authority will grant approval for narsoplimab in any indication;

● our plans for the commercial launch of narsoplimab following any regulatory approval and our estimates and expectations regarding coverage and reimbursement for any approved products;

● our expectations regarding the clinical, therapeutic and competitive benefits and importance of our drug candidates;

● our ability to design, initiate and/or successfully complete clinical trials and other studies for our drug candidates and our plans and expectations regarding our ongoing or planned clinical trials;

● our expectations regarding: our ability to recruit and enroll patients in any ongoing or planned clinical trial; whether we can capitalize on the financial and regulatory incentives provided by orphan drug designations granted by FDA, the European Commission (“EC”), or the EMA; and whether we can utilize the opportunities for expedited development and review that may be provided by fast-track or breakthrough therapy designations granted by FDA;

● our expectations about the commercial competition that our drug candidates, if commercialized, face or may face;

​

● our involvement in existing or potential claims, legal proceedings and administrative actions, and the merits, potential outcomes and effects of both existing and potential claims, legal proceedings and administrative actions, as well as regulatory determinations, on our business, prospects, financial condition and results of operations;

● the extent of protection that our patents provide and that our pending patent applications will provide, if patents are issued from such applications, for our technologies, programs, and drug candidates;

● the factors on which we base our estimates for accounting purposes and our expectations regarding the effect of changes in accounting guidance or standards on our operating results; and

● our expected financial position, performance, revenues, growth, costs and expenses, magnitude of net losses and the availability of resources.

Given these risks, uncertainties and other factors, actual results or anticipated developments may not be realized or, even if substantially realized, may not have the expected consequences to or effects on our company, business or operations. Accordingly, you should not place undue reliance on these forward-looking statements, which represent our estimates and assumptions only as of the date of the filing of this Quarterly Report on Form 10-Q. You should read this Quarterly Report on Form 10-Q completely and with the understanding that our actual results in subsequent periods may differ materially from current expectations.
