Clinical and Manufacturing Development Timeline


On June 14, 2017, we announced alignment with the FDA on our Good Manufacturing Practice, or GMP, commercial manufacturing process for AVXS-101 following the receipt of minutes from the Type B Chemistry Manufacturing and Controls, or CMC, meeting with the FDA. This alignment includes support for our proposed GMP commercial manufacturing process, our proposed analytical methods and corresponding qualification and validation plans — inclusive of key release assays such as potency, purity and identity — and our proposed comparability protocol, which helps assess how similar the product derived from the GMP process is to the original product used in the Phase 1 trial of AVXS-101 in patients with SMA Type 1.


Key components of our scalable, GMP commercial manufacturing process are as follows:


·                  we will continue to utilize HEK293 cells and an adherent cell line;


·                  our commercial-scale GMP process will utilize a novel adherent cell culture approach that can more reliably produce product and has greater surface area to potentially increase productivity relative to Hyperstacks;


·                  we have implemented additional upstream and downstream process development improvements to meet global regulatory GMP expectations as well as to meet projected patient demand, if approved; and


·                  we intend to utilize our GMP process for all clinical and commercial needs moving forward, including our new programs in Rett syndrome and ALS described below.


In response to a request from the FDA, we intend to complete the implementation of our potency assay qualification plan, including three independent runs, prior to initiation of upcoming clinical trials. This assay utilizes the Delta 7 mouse model, which has been used historically to assess AVXS-101 potency, but now incorporates additional elements to make it acceptable to global regulatory authorities. We have initiated the work necessary to meet that request and we expect to have the data from these production runs to submit to the FDA in the August 2017 timeframe.  Pending agreement from the FDA that the data from these production runs are sufficient, we intend to initiate our pivotal trial of AVXS-101 in SMA Type 1 in the United States and a Phase 1/2a clinical trial of AVXS-101 in SMA Type 2 in the United States later in the third quarter of 2017.


Additionally, we are currently conducting comparability work to assess the similarity of key characteristics of the AVXS-101 product used in our Phase 1 clinical trial in SMA Type 1, which was manufactured by the Nationwide Children’s Hospital, or NCH, to the product derived from our new GMP manufacturing process. Data from this comparability work will be incorporated into the data package, and will include the above mentioned potency qualification work, along with the full Phase 1 clinical data, that will be reviewed and discussed at our end-of-Phase 1 meeting with the FDA, which we anticipate requesting later in August 2017. We expect that this meeting will help further inform the regulatory pathway for AVXS-101. We anticipate providing an update on the outcome
