competitors’ products could limit the demand, and the price we are able to charge, for any product candidate that we may develop and commercialize.

Even if we obtain and maintain approval for AVXS‑101 from the FDA, we may never obtain approval for AVXS‑101 outside of the United States, which would limit our market opportunities and adversely affect our business.

Approval of a product candidate in the United States by the FDA does not ensure approval of such product candidate by regulatory authorities in other countries or jurisdictions, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or by the FDA. Sales of AVXS‑101 outside of the United States will be subject to foreign regulatory requirements governing clinical trials and marketing approval. Even if the FDA grants marketing approval for a product candidate, comparable regulatory authorities of foreign countries also must approve the manufacturing and marketing of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and more onerous than, those in the United States, including additional preclinical studies or clinical trials. In many countries outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that country. In some cases, the price that we intend to charge for our product candidates, if approved, is also subject to approval. We intend to submit a marketing authorization application to the EMA for approval of AVXS‑101 in the European Union, but obtaining such approval from the European Commission following the opinion of the EMA is a lengthy and expensive process. Even if a product candidate is approved, the FDA or the European Commission, as the case may be, may limit the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time‑consuming additional clinical trials or reporting as conditions of approval. Regulatory authorities in countries outside of the United States and the European Union also have requirements for approval of product candidates with which we must comply prior to marketing in those countries. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of AVXS‑101 in certain countries.

Further, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries. Also, regulatory approval for AVXS‑101 may be withdrawn. If we fail to comply with the regulatory requirements, our target market will be reduced and our ability to realize the full market potential of AVXS‑101 will be harmed and our business, financial condition, results of operations and prospects will be adversely affected.

Preclinical testing of our gene therapy product candidates for Rett syndrome and genetic ALS may not result in our advancement of these programs into clinical trials.


Although a substantial amount of our efforts to date have focused on the development of AVXS-101 for SMA, a key element of our strategy is to discover, develop and potentially commercialize a portfolio of product candidates to treat other rare and life-threatening neurological genetic diseases. In furtherance of that strategy, we announced that we had entered into a license agreement with REGENXBIO to develop and commercialize gene therapy treatments to treat two rare monogenic disorders: Rett syndrome and genetic ALS. Our development efforts for our Rett syndrome and ALS programs are at an extremely early stage, and we have not yet completed IND-enabling preclinical studies for either of these programs. It is possible that future research and preclinical development of these programs may not establish sufficient indications of clinical benefit or acceptable tolerability to support the submission of an IND for one or both of these programs, in which case we may never initiate clinical trials, and we may be forced to suspend development activities for one or both of these programs. If we are not able to advance these programs into clinical trials, we will not be able to commercialize products for these indications, which would have a material adverse effect on our future business prospects, financial condition and results of operations.
