FDA Approves Zulresso (brexanolone) for the Treatment of Postpartum Depression

U.S. Food and Drug Administration   approved Zulresso (brexanolone) injection for intravenous (IV) use for the treatment of postpartum depression (PPD) in adult women. This is the first drug approved by the FDA specifically for PPD.

"Postpartum depression is a serious condition that, when severe, can be life-threatening. Women may experience thoughts about harming themselves or harming their child. Postpartum depression can also interfere with the maternal-infant bond. This approval marks the first time a drug has been specifically approved to treat postpartum depression, providing an important new treatment option," said Tiffany Farchione, M.D., acting director of the Division of Psychiatry Products in the FDA’s Center for Drug Evaluation and Research. "Because of concerns about serious risks, including excessive sedation or sudden loss of consciousness during administration, Zulresso has been approved with a Risk Evaluation and Mitigation Strategy (REMS) and is only available to patients through a restricted distribution program at certified health care facilities where the health care provider can carefully monitor the patient."

PPD is a major depressive episode that occurs following childbirth, although symptoms can start during pregnancy. As with other forms of depression, it is characterized by sadness and/or loss of interest in activities that one used to enjoy and a decreased ability to feel pleasure (anhedonia) and may present with symptoms such as cognitive impairment, feelings of worthlessness or guilt, or suicidal ideation.

Zulresso will be available only through a restricted program called the Zulresso REMS Program that requires the drug be administered by a health care provider in a certified health care facility. The REMS requires that patients be enrolled in the program prior to administration of the drug. Zulresso is administered as a continuous IV infusion over a total of 60 hours (2.5 days). Because of the risk of serious harm due to the sudden loss of consciousness, patients must be monitored for excessive sedation and sudden loss of consciousness and have continuous pulse oximetry monitoring (monitors oxygen levels in the blood). While receiving the infusion, patients must be accompanied during interactions with their child(ren). The need for these steps is addressed in a Boxed Warning in the drug’s prescribing information. Patients will be counseled on the risks of Zulresso treatment and instructed that they must be monitored for these effects at a health care facility for the entire 60 hours of infusion. Patients should not drive, operate machinery, or do other dangerous activities until feelings of sleepiness from the treatment have completely gone away.

The efficacy of Zulresso was shown in two clinical studies in participants who received a 60-hour continuous intravenous infusion of Zulresso or placebo and were then followed for four weeks. One study included patients with severe PPD and the other included patients with moderate PPD. The primary measure in the study was the mean change from baseline in depressive symptoms as measured by a depression rating scale. In both placebo controlled studies, Zulresso demonstrated superiority to placebo in improvement of depressive symptoms at the end of the first infusion. The improvement in depression was also observed at the end of the 30-day follow-up period.

The most common adverse reactions reported by patients treated with Zulresso in clinical trials include sleepiness, dry mouth, loss of consciousness and flushing. Health care providers should consider changing the therapeutic regimen, including discontinuing Zulresso in patients whose PPD becomes worse or who experience emergent suicidal thoughts and behaviors.

FDA Approves Rocklatan (netarsudil and latanoprost ophthalmic solution) for the Reduction of Intraocular Pressure in Open-Angle Glaucoma or Ocular Hypertension

In continuation of my update on latanoprost 

Aerie Pharmaceuticals, Inc. (NASDAQ:AERI) (Aerie or the Company), an ophthalmic pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye,   announced that the U.S. Food and Drug Administration (FDA) has approved Rocklatan (netarsudil and latanoprost ophthalmic solution) 0.02%/0.005% to reduce elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. 

Rocklatan is a once-daily eye drop that is a fixed-dose combination of latanoprost, the most widely-prescribed prostaglandin analog (PGA), and netarsudil, the active ingredient in Rhopressa (netarsudil ophthalmic solution) 0.02%, a first-in-class Rho kinase (ROCK) inhibitor specifically designed to target the trabecular meshwork (the eye’s principal drainage pathway). The diseased trabecular meshwork is considered to be the main cause of elevated IOP in open-angle glaucoma and ocular hypertension. Rhopressa® works by restoring outflow through the trabecular meshwork, while latanoprost increases fluid outflow through a secondary mechanism known as the uveoscleral pathway.

Aerie launched Rhopressa® in the United States in April 2018. The Company plans to launch Rocklatan™ in the United States in the second quarter of 2019.

“We are in the unique position of receiving FDA approval on a second glaucoma treatment less than a year from the U.S. launch of Rhopressa®,” said Vicente Anido, Jr., Ph.D., chairman and chief executive officer at Aerie. “Together, Rocklatan™ and Rhopressa® give us a broad therapeutic franchise, based on our ROCK inhibitor netarsudil, that addresses many of the needs of clinicians and patients in a wide variety of treatment settings. Our existing salesforce, which has been calling on U.S. eye-care professionals since last May, is very well positioned to introduce Rocklatan™ to these doctors and help them understand the clinical utility of both products in the care of their patients with glaucoma. We have also been working diligently on securing favorable reimbursement for our products, with Rhopressa® now enjoying broad commercial and Medicare Part D coverage, and Rocklatan™ already under review by major payers.”

The FDA approval of Rocklatan is based on data from two Phase 3 registration trials, MERCURY 1 and MERCURY 2. In these studies, Rocklatan™ achieved its primary 90-day efficacy endpoint as well as positive 12-month safety and efficacy results, demonstrating statistically superior IOP reduction over latanoprost and netarsudil at every measured time point. More than 60% of patients taking Rocklatan™ in the two MERCURY studies achieved an IOP reduction of 30% or more, a frequency that was nearly twice that achieved by participants taking latanoprost alone. Rocklatan™ also helped more patients get to low target pressures. Nearly twice as many patients taking Rocklatan™ reached 16 mmHg or lower and nearly three times as many reached 14 mmHg or lower compared to latanoprost.

In the two MERCURY studies, Rocklatan treatment was associated with generally mild and tolerable ocular adverse events, with minimal systemic side effects. The most common ocular adverse event in controlled clinical studies with Rocklatan™ was conjunctival hyperemia. Ninety percent of patients who experienced hyperemia reported it as mild and 5% discontinued because of it. Other common ocular adverse effects reported in the studies include instillation site pain, corneal verticillata and conjunctival hemorrhage.

About Rocklatan

Indications and Usage

Rocklatan (netarsudil and latanoprost ophthalmic solution) 0.02%/0.005% is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension.

Select Important Safety Information

Although not observed in the two MERCURY studies, latanoprost has been reported to cause changes to pigmented tissues, including pigmentation of the iris, periorbital tissue (eyelid) and eyelashes. Iris pigmentation is likely to be permanent. Latanoprost has also been associated with gradual changes to eyelashes including increased length, thickness and number of lashes. These changes are usually reversible.
