FDA Approves Dextenza (dexamethasone ophthalmic insert) for the Treatment of Ocular Pain Following Ophthalmic Surgery

In continuation of my update on Dexamethasone

Ocular Therapeutix™, Inc. a biopharmaceutical company focused on the formulation, development, and commercialization of innovative therapies for diseases and conditions of the eye, today announced that the U.S. Food and Drug Administration (FDA) has approved Dextenza (dexamethasone ophthalmic insert) 0.4mg for intracanalicular use for the treatment of ocular pain following ophthalmic surgery.

“We are extremely pleased to announce the approval of Dextenza, coming so soon after our pre-approval inspection and approximately one month ahead of the PDUFA date,” said Antony Mattessich, the Company’s President and Chief Executive Officer. “Just over a year ago, we set out to augment our scientific and formulation expertise with individuals who have the skills and experience to create a first-class team to get Dextenza approved and become a commercial stage biopharmaceutical company. We believe this approval is a major external validation of the drug delivery technology platform, and also of the transformation that has taken place at Ocular. While we are excited by the approval of our first drug product, our goal has always been to bring Dextenza to as many patients as possible in the near term and to revolutionize ophthalmic drug delivery by making drops obsolete. We now turn our efforts towards the successful commercial launch of Dextenza.”

Dextenza is the first FDA-approved intracanalicular insert delivering dexamethasone to treat post-surgical ocular pain for up to 30 days with a single administration. The approval of Dextenza was based on (i) demonstrated efficacy in two randomized, vehicle-controlled Phase 3 studies in which a statistically significantly higher incidence of subjects were pain free at day 8 post-cataract surgery compared to the vehicle control group and (ii) safety in the two Phase 3 studies as well as a third randomized, vehicle-controlled Phase 2 study. The Company believes the delivery profile represents a differentiated and potentially transformational new product for patients and physicians. For patients, Dextenza offers the convenience of a full course of post-surgical steroid treatment with a physician’s one-time placement of a single intracanalicular insert. Dextenza has the potential to replace a complex eye drop regimen that under the current standard of care requires up to 70 topical ocular steroid drops.

“Compliance with taking eye drops after eye surgery is very challenging for patients and a concern for surgeons,” said Michael Goldstein, MD, Chief Medical Officer. “The approval of Dextenza offers surgeons the opportunity to treat patients with a preservative-free steroid after surgery with the placement of a single drug insert. With this product, patients may be liberated from having to deal with the burdensome regimen of using steroid eye drops after ophthalmic surgery.”

In connection with the commercial launch of Dextenza, Ocular Therapeutix also submitted an application for transitional pass-through payment status after receiving FDA approval and intends to submit an application for a J-code ahead of the January 2019 deadline.

FDA Approval to Expand the Age Range for Ravicti (glycerol phenylbutyrate) Oral Liquid to Include Newborns

  In  continuation of my update on   glycerol phenyl butyrate   

        Horizon Pharma plc (NASDAQ: HZNP) announced the U.S. Food and Drug Administration (FDA) has approved a supplemental new drug application (sNDA) to expand the age range for Ravicti (glycerol phenylbutyrate) Oral Liquid to include infants younger than two months of age living with a urea cycle disorder (UCD).

Ravicti is now FDA-approved for use as a nitrogen-binding agent for chronic management of UCDs in adults and children of all ages who cannot be managed by dietary protein restriction and/or amino acid supplementation alone. Ravicti must be used with dietary protein restriction and, in some cases, dietary supplements. Ravicti is not indicated for treatment of acute hyperammonemia in patients with UCDs, and its safety and efficacy for the treatment of n-acetylglutamate synthase (NAGS) deficiency has not been established.

“The FDA approval of Ravicti for children younger than two months provides a new alternative for the management of patients with a UCD that is easy to dose and administer to infants given the liquid formulation,” said Nicola Longo, M.D., Ph.D., clinical geneticist at Primary Children’s Hospital and the University of Utah Hospital, and a lead investigator of a clinical study evaluating Ravicti for newborns. “UCDs are severe and can be life-threatening. We hope that the combination of early diagnosis – through newborn screening or by measurement of ammonia levels – and the availability of novel treatments, such as this one, can help to improve the outcome of affected patients.”

A study was conducted to assess safety, efficacy and pharmacokinetics in pediatric patients with UCDs two months of age and younger (n=16). In the study, 10 patients transitioned to Ravicti from sodium phenylbutyrate, three transitioned from intravenous sodium benzoate and sodium phenylacetate, and three were treatment naïve. Patients were treated with Ravicti for an average of 10.7 months. Results demonstrated safety and efficacy in children younger than two months, with Ravicti-treated patients maintaining stable ammonia levels relative to their pre-study enrollment. In addition, mean ammonia levels were lower during treatment with Ravicti compared to baseline values.

“As we increase our efforts to develop new investigational medicines for people living with rare and rheumatic diseases, Horizon continues to seek ways to better serve patients with our current medicines,” said Elizabeth Thompson, Ph.D., vice president, clinical development, rare diseases, Horizon Pharma. “The FDA approval of Ravicti for children under the age of two months is a milestone in our efforts to help people living with UCDs, and we are proud to be bringing a new treatment option to the vulnerable newborn patient population.”

A UCD is a rare genetic disorder that affects approximately 1 in 35,000 live births in the United States. It is caused by an enzyme deficiency in the urea cycle, a process that is responsible for converting excess ammonia from the bloodstream and ultimately removing it from the body. Because of this, people with a UCD experience hyperammonemia, or elevated ammonia levels in their blood, that can then reach the brain and cause irreversible brain damage, coma or death. UCD symptoms may first occur at any age depending on the severity of the disorder, with more severe defects presenting earlier in life.
