Saol Therapeutics announces FDA acceptance of New Drug Application for SL1009 for treatment of Pyruvate Dehydrogenase Complex Deficiency

ROSWELL, Ga, DUBLIN and HAMILTON, Bermuda, January 28, 2025 – Saol Therapeutics, a privately held, clinical-stage pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for SL1009, Sodium Dichloroacetate Oral Solution (DCA). DCA will be used with a proprietary genetic test to treat an orphan pediatric mitochondrial disease, Pyruvate Dehydrogenase Complex Deficiency (PDCD)1. The FDA granted Priority Review for the NDA and has set a goal date of May 27, 2025, under the Prescription Drug User Fee Act (PDUFA). Priority review is designated to applications for drugs that, if approved, would provide a significant improvement in safety or effectiveness of the treatment, prevention or diagnosis of a serious medical condition. SL1009 has previously been granted Orphan Drug and Fast Track Designations. SL1009 has also been granted a Rare Pediatric Disease Designation by the FDA and thus is eligible for a Priority Review Voucher (PRV).


PDCD is a rare and life-threatening mitochondrial disorder of carbohydrate oxidation that mostly affects the nervous system and skeletal muscle and leads to decreased ATP production and energy failure. DCA is a targeted therapy that inhibits Pyruvate Dehydrogenase Kinase (PDK) to stimulate residual Pyruvate Dehydrogenase Complex (PDC) activity and increase energy (ATP) production by mitochondria.

"This NDA acceptance brings us one step closer to addressing the critical health challenges faced by these children and their families, where no approved treatment is currently available," said Dave Penake, Chief Executive Officer of Saol Therapeutics. “Reaching this regulatory milestone is both a significant scientific achievement and a deeply meaningful moment for everyone who has dedicated themselves to advancing this therapy. Further, designating our application for priority review reaffirms that the FDA views PDCD as a serious condition”


The NDA is supported by results from a Phase 3 double-blind placebo-controlled cross-over study (SL1009-01) and a survival study (SL1009-02). The totality of evidence submitted for review in the NDA includes mechanistic characterization, along with nonclinical and clinical evidence to demonstrate the safety and clinical benefit of DCA in PDCD patients.

DCA is not currently approved for any indication in the United States.

 

About Pyruvate Dehydrogenase Complex Deficiency (PDCD)

PDCD is a mitochondrial disorder of carbohydrate oxidation that mostly affects the nervous system and skeletal muscle and leads to decreased ATP production and energy failure. It is estimated that 300-500 patients are treated in expert centers in the US, and the overall prevalence is thought to be as high as 2,000. PDCD is the most common cause of congenital lactic acidosis, a life-threatening condition that may occur as early as the neonatal period. Patients suffering from PDCD may also exhibit extreme tiredness (lethargy), poor feeding, rapid breathing (tachypnea), and other signs of neurological and neuromuscular dysfunction such as developmental delay, low muscle tone (hypotonia), abnormal eye movements and seizures. Signs and symptoms usually begin soon after birth but may appear later in childhood2.

There are currently no FDA-approved therapies for PDCD.

Georgia Life Sciences has joined 43 state and regional life sciences organizations in signing a national Council of State Bioscience Associations (CSBA) letter calling on Congress to take immediate action on three bipartisan policy priorities that are essential to sustaining U.S. leadership in biomedical innovation and supporting patients nationwide. With Congress back in session and several critical programs at risk of expiring, the letter urges congressional leaders to advance the following provisions without delay: 1. Reauthorize the Rare Pediatric Disease Priority Review Voucher (PPRV) Program The PPRV program has been instrumental in incentivizing the development of therapies for children with rare and life-threatening conditions. Its lapse threatens to slow or halt research that families across the country are counting on. 2. Extend the SBIR/STTR Programs The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs provide crucial early-stage capital for emerging biotech and medtech companies—many of them in Georgia. Without reauthorization, hundreds of innovative small businesses face uncertainty, jeopardizing new therapies, diagnostics, and technologies in the pipeline, 3. Advance PBM Transparency Reforms Greater transparency and accountability within pharmacy benefit manager (PBM) practices are needed to ensure that savings reach patients and employers. Reforming PBM operations is essential to strengthening access and affordability across the healthcare system. A Unified Message from the Life Sciences Community The sign-on letter reflects broad, bipartisan alignment across the national life sciences ecosystem: researchers, entrepreneurs, investors, patient advocates, and state associations all share a common message— these programs underpin America’s global competitiveness and are vital to patients who rely on continued scientific progress. Georgia Life Sciences has shared the letter with members of Georgia’s congressional delegation and will continue engaging with policymakers to emphasize the importance of swift action.

Georgia Life Sciences is proud to stand with patient advocates, providers, and employers across the state in urging Congress to take meaningful action on pharmacy benefit manager (PBM) reform. We recently signed on to a joint letter to Georgia’s Congressional Delegation stressing the urgent need for transparency, fair practices, and policies that ensure savings flow directly to patients.

Georgia Life Sciences’ CEO, Maria Thacker Goethe shares her perspective on the value of Georgia’s research universities in this month’s issue of Georgia Trend. “Georgia research institutions have felt a very significant impact from the federal rollbacks, specifically in NIH and NSF funding. Thacker Goethe’s message about the impact of research cuts is simple: Disruption shatters the foundational trust researchers have in grant continuity….” To read the full article, click here .
