Using the TANGO approach and a deep understanding of RNA science, Stoke researchers design ASOs that bind to pre-mRNA and help the target genes produce more protein. TANGO aims to restore missing proteins by increasing or stoking protein output from healthy genes, thus compensating for the non-functioning copy of the gene.

We further showed that in OPA1 haploinsufficient human cells, ASO-14-mediated increase in OPA1 protein translates to improved mitochondrial function as measured by the substantial restoration of ATP levels in the treated cells (Exhibit 15 below). ATP is produced by the mitochondria and is the key energy carrying molecule in cells. We observed a 20% ATP deficit in OPA1 +/- HEK293.

The voucher entitles the sponsor to priority review of one subsequent marketing application.
We have also made investments in automated equipment to efficiently screen large numbers of ASOs. ASO arrays utilize clinically translatable previously-validated ASO chemistries, such as 2’ methoxyethyl phosphorothioate and PMO. Hit compounds are evaluated in vivo to identify lead ASOs that possess suitable efficacy and safety to merit preclinical development.

Importantly, we believe none of the drugs in clinical development address the underlying genetic cause of Dravet syndrome. However, one company (Encoded Therapeutics) has announced a clinical development plan for a gene regulation therapy program in Dravet syndrome that may address the underlying genetic cause of Dravet syndrome. Our second product candidate, STK-002, is in development for treatment of ADOA.

Biggest changeIf we or our collaborators are unable to develop, obtain regulatory approval for and commercialize STK-001, STK-002 and our future product candidates, or if we experience significant delays in doing so, our business will be materially harmed. Success in early preclinical studies or clinical trials may not be indicative of results obtained in later preclinical studies and clinical trials, including in our Dravet syndrome program or our ADOA program. Even if we complete the necessary preclinical studies and clinical trials, we cannot predict when, or if, we will obtain regulatory approval to commercialize a product candidate and the approval may be for a narrower indication than we seek. Certain of the diseases we seek to treat have low prevalence, and it may be difficult to identify patients with these diseases, which may lead to delays in enrollment for our trials or slower commercial revenue growth if STK-001, STK-002 or our future product candidates are approved. If clinical trials of STK-001, STK-002 or any other product candidate that we develop fail to demonstrate safety and efficacy to the satisfaction of FDA or foreign regulatory authorities or do not otherwise produce favorable results, we may incur additional costs or experience delays in completing, or ultimately may be unable to complete, the development and commercialization of such product candidate. We may not be successful in our efforts to use TANGO to expand our pipeline of product candidates and develop marketable products. Any product candidate for which we obtain marketing approval will be subject to extensive post-marketing regulatory requirements and could be subject to post-marketing restrictions or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates, when and if any of them are approved. Our failure to obtain regulatory approval in international jurisdictions would prevent us from marketing our product candidates outside the United States. STK-001, STK-002 or our future product candidates may cause undesirable and unforeseen side effects or be perceived by the public as unsafe, which could delay or prevent their advancement into clinical trials or regulatory approval, limit the commercial potential or result in significant negative consequences. A Rare Pediatric Disease designation by the FDA does not guarantee that the new drug application (“NDA”) for the product will qualify for a priority review voucher upon approval, and it does not lead to a faster development or regulatory review process, or increase the likelihood that STK-001, STK-002 or our future product candidates will receive marketing approval. 36 A Fast Track Designation by the FDA, even if granted for STK-001, STK-002 or our future product candidates, may not lead to a faster development or regulatory review or approval process, and would not increase the likelihood that our product candidates will receive marketing approval. A Breakthrough Therapy Designation by the FDA, even if granted for STK-001, STK-002 or our future product candidates may not lead to a faster development or regulatory review or approval process, and it would not increase the likelihood that the product candidates will receive marketing approval. Enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and may affect the prices we may set. The commercial success of our product candidates, including STK-001 and STK-002 will depend upon their degree of market acceptance by providers, patients, patient advocacy groups, third-party payors and the general medical community. The pricing, insurance coverage and reimbursement status of newly approved products is uncertain.
