In evaluating our business, you should carefully consider the following risks in addition to the other information in this report. Any of the following risks could materially and adversely affect our business, results of operations, financial condition or your investment in our securities, and many are beyond our control. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also adversely affect our business.

Risks Specific to our Company in connection with our Research and Development Activities

The regulatory approval and marketing authorization process is expensive, time-consuming and uncertain and may prevent our partners or us from obtaining approvals to commercialize some or all of our drug candidates.

The research, testing, manufacturing, selling and marketing of drugs are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries. Neither we nor our partners are permitted to market our potential drugs in the United States until we receive approval of an NDA from the FDA. We have never received NDA or other marketing approval for any of our drug candidates. Obtaining NDA approval is a lengthy, expensive and uncertain process. The FDA and foreign regulatory agencies can delay, limit or deny approval of a drug candidate for many reasons, including, but not limited to, a determination that a drug candidate is not safe or effective, that the data from non-clinical testing and clinical trials is insufficient and that our partner’s or the contract manufacturer’s processes or facilities are not in compliance with GMP. Even if we receive regulatory approval to manufacture and sell a drug in a particular regulatory jurisdiction, other jurisdictions’ regulatory authorities may not approve that drug for manufacture and sale. 

Regulatory approval of an NDA, NDA supplement or other marketing application for our drug candidates is never guaranteed. For example, our NDA for omecamtiv mecarbil for the treatment of HFrEF resulted in a complete response letter notwithstanding the fact that GALACTIC-HF met its primary efficacy endpoint. As an example of the NDA for omecamtiv mecarbil illustrates, while we have submitted an NDA to FDA and an MAA to EMA for aficamten, such marketing applications may not lead to any regulatory approvals, or may result in requirements to conduct additional clinical trials prior to any potential approvals, which would increase our development costs and delay or preclude any revenue from commercial sales of aficamten and/or our other drug candidates.
