Dicerna Announces Late-Breaking Data from the PHYOX Phase 1 Clinical Trial of DCR-PHXC Will Be Presented at ASN Kidney Week 2018
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Oct 5, 2018--Dicerna Pharmaceuticals, Inc. (Nasdaq: DRNA), a leading developer of investigational ribonucleic acid interference (RNAi) therapeutics, today announced that late-breaking data from the PHYOX Phase 1 trial of DCR-PHXC for the treatment of primary hyperoxaluria (PH) will be presented at the American Society of Nephrology (ASN) Annual Kidney Week 2018, being held October 23-28 in San Diego. The poster presentation will include clinical data from the ongoing PHYOX Phase 1 study in patients with primary hyperoxaluria type 1 and type 2 (PH1 and PH2). PH is a family of severe, rare, inherited disorders of the liver that often result in kidney failure.
Details for the poster presentation are as follows:Session Title: Late-Breaking Clinical Trials Posters [LB-PO] Poster Title: Poster Number: TH-PO1167 Date/Time: Thursday, October 25, 2018, 10:00 a.m. - 12:00 p.m. PT Presenter: Dr. Bernd Hoppe, M.D., PHYOX investigator and head of the Division of Pediatric Nephrology in the Department of Pediatrics at the University of Bonn, Germany
The Company recently reported initial proof-of-concept data from the PHYOX Phase 1 trial demonstrating significant and sustained reduction in urinary oxalate levels following single-dose administration in adults with PH1 and PH2.

DCR-PHXC is an investigational drug in development for the treatment of all forms of primary hyperoxaluria (PH), and the most advanced product candidate utilizing Dicerna’s GalXC TM technology. GalXC is a proprietary platform invented by Dicerna scientists to discover and develop next-generation RNAi-based therapies designed to silence disease-driving genes in the liver. In animal models of PH, DCR-PHXC selectively silences lactase dehydrogenase (LDHA) in the liver, blocking the excess production of oxalate, a hallmark of the disease. In preclinical studies of DCR-PHXC, the compound was well tolerated with no adverse effects in the liver. Studies have shown that people who are completely deficient in LDHA show no liver dysfunction and can lead normal lives. LDHA deficiency in the liver might be beneficial for patients with PH, as the LDHA enzyme is implicated in the abnormal production of oxalate in PH, which in turn is responsible for the severe damage to kidneys and other organ systems in patients with PH.
About Primary Hyperoxaluria (PH)
Primary hyperoxaluria (PH) is a family of severe, rare, genetic liver disorders characterized by overproduction of oxalate, a natural chemical in the body that is normally eliminated as waste through the kidneys. In patients with PH, the kidneys are unable to eliminate the large amount of oxalate that is produced, and the accumulation of oxalate can result in severe damage to the kidneys and other organs. Currently, there are no approved therapies for the treatment of PH.
There are three known types of PH, each of which results from a mutation in a specific gene, as well as PH for which the molecular basis remains unknown, often referred to as idiopathic PH (IPH) or “no mutation detected” (NMD) PH. The known PH mutations cause a decrease in the activity of a specific enzyme in the liver, triggering an increase in oxalate production. In each case the decreased enzyme activity changes the balance of intermediary metabolites, resulting in overproduction of oxalate. The three genetically known types of PH are: 1,2PH1, which is caused by a mutation in the AGXT gene, causing a deficiency of the enzyme alanine:glyoxylate-aminotransferase (AGT) PH2, which is caused by a mutation in the GRHPR gene, causing a deficiency of the enzyme glyoxylate/hydroxypyruvate reductase (GR/HPR) PH3, which is caused by a mutation in the HOGA1 gene, causing a deficiency of the enzyme 4-hydroxy-2-oxoglutarate aldolase (HOGA)
Patients with severe PH often undergo both liver and kidney transplants, which are major surgical procedures, and subsequently must take immunosuppressant drugs for the rest of their lives. Patients with decreased renal function may also experience oxalosis, which involves a build-up of oxalate in other organs such as the bone, skin, heart, and retina, possibly causing other concomitant, debilitating complications.
PH occurs in an estimated 1 in 120,000 live births around the world. 3 The estimated genetic prevalence of PH1 is 1 in 151,887 births, which implies more than 5,000 patients in the United States and European Union have the disease. 3 The estimated genetic prevalence of PH2 is 1 in 310,055 and that of PH3 is 1 in 135,866. 3 The median age at the first appearance of PH1 symptoms is 5.8 years. 4 The median age at diagnosis of PH1 is between 4.2 and 11.5 years, depending on whether nephrocalcinosis (calcification in the renal parenchyma, the functional part of the kidney) is present. 5 Fifty percent of patients with PH1 reach end-stage renal disease (ESRD) by their mid-30s. 2
