On track for full commercial launch in the U.S. in late June

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Sage Therapeutics (NASDAQ: SAGE), a biopharmaceutical company developing
novel medicines to treat life-altering central nervous system (CNS)
disorders, today announced that the U.S. Drug Enforcement Administration
(DEA) has placed ZULRESSO™ (brexanolone) injection into Schedule IV of
the Controlled Substances Act. ZULRESSO, which was approved by the U.S.
Food and Drug Administration (FDA) on March 19, 2019, is the first and
only treatment specifically approved for postpartum depression (PPD),
the most common medical complication of childbirth.


With this decision, the product label for ZULRESSO will be finalized.
The Company expects to launch ZULRESSO in late June as planned. ZULRESSO
is administered via continuous intravenous (IV) infusion for 2.5 days
under the supervision of healthcare providers in sites of care certified
under the ZULRESSO Risk Evaluation and Mitigation Strategy (REMS)
program. The one-time infusion offers the potential for rapid resolution
of depressive symptoms of PPD.

“Historically, women suffering from PPD may have avoided seeking help
because of the stigma, lack of a specifically approved treatment and the
complicated journey to care – challenges that have been difficult for
women with PPD and their families to overcome,” said Mike Cloonan, chief
business officer at Sage. “Sage is taking on those challenges and
creating a family-centric approach to ZULRESSO availability by enabling
pathways to care including building our patient support organization,
where we will provide a range of meaningful support resources to women
with PPD and their families to help navigate the ZULRESSO treatment
journey. We also continue to activate Centers of Excellence across the
country with the goal of supporting a positive patient experience and
broad availability to ZULRESSO for women with PPD.”

The Company continues to focus on identifying and activating Centers of
Excellence (COE) and other healthcare settings capable of administering
ZULRESSO to women with PPD. The key criteria for identifying a potential
COE or other sites of care include: a PPD healthcare provider champion;
the ability to secure appropriate payer reimbursement for ZULRESSO; and
the capability to meet the requirements for certification under the
ZULRESSO REMS, which includes monitoring by qualified trained staff,
adherence to specific protocols and the maintenance of a patient
registry. The Company continues to execute against its planned
go-to-market strategy with a focus on the commercial launch of ZULRESSO
in late June.

About Postpartum Depression
Postpartum depression (PPD) is
the most common medical complication of childbirth. PPD is a distinct
and readily identified major depressive episode that can occur during
pregnancy or after giving birth. Expert opinions vary as to the timing
of the onset of PPD, ranging from onset during pregnancy up to 4-weeks
postpartum and onset during pregnancy up to 12-months postpartum. PPD
may have devastating consequences for a woman and for her family, which
may include significant functional impairment, depressed mood and/or
loss of interest in her newborn, and associated symptoms of depression
such as loss of appetite, difficulty sleeping, motor challenges, lack of
concentration, loss of energy and poor self-esteem. PPD can be a
life-threatening condition due to the risk of suicide, a leading cause
of maternal death following childbirth. PPD is estimated to affect
approximately one in nine women who have given birth in the U.S. and
400,000 women annually. More than half of these cases may go undiagnosed
without proper screening.

About ZULRESSO™ (brexanolone) injection

medicine specifically approved by the U.S. Food and Drug
Administration (FDA) for the treatment of postpartum depression (PDD) in
adults, is a positive allosteric modulator of both synaptic and
extrasynaptic GABAA receptors. Allosteric modulation of
neurotransmitter receptor activity results in varying degrees of desired
activity rather than complete activation or inhibition of the receptor.

What is ZULRESSO?

ZULRESSO™ (brexanolone) CIV is a prescription medicine used in adults to
treat a certain type of depression called Postpartum Depression.

IMPORTANT SAFETY INFORMATION

What is the most important information I should know about ZULRESSO?

ZULRESSO can cause serious side effects, including:

  • Excessive sedation and sudden loss of consciousness. ZULRESSO
    may cause you to feel very sleepy (excessive sedation) or pass out
    (loss of consciousness). Your healthcare provider should check you for
    symptoms of excessive sleepiness every 2 hours while you are awake.

    • During your ZULRESSO infusion, tell your healthcare provider right
      away if you feel like you cannot stay awake during the time you
      are normally awake or if you feel like you are going to pass out.
      Your healthcare provider may lower your dose or stop the infusion
      until symptoms go away.
    • You must have a caregiver or family member with you to help care
      for your child(ren) during your ZULRESSO infusion.
  • Because of the risk of serious harm resulting from excessive sedation
    or sudden loss of consciousness, ZULRESSO is only available through a
    restricted program called the ZULRESSO REMS.

Before receiving ZULRESSO, tell your healthcare provider about all
your medical conditions, including if you:

  • drink alcohol
  • have kidney problems
  • are pregnant or think you may be pregnant. It is not known if ZULRESSO
    will harm your unborn baby.

    • There is a pregnancy registry for females who are exposed to
      ZULRESSO during pregnancy. The purpose of the registry is to
      collect information about the health of females exposed to
      ZULRESSO and their baby. If you become pregnant during treatment
      with ZULRESSO, talk to your healthcare provider about registering
      with the National Pregnancy Registry for Antidepressants at
      1-844-405-6185 or visit https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/
  • are breastfeeding or plan to breastfeed. ZULRESSO passes into breast
    milk. Talk to your healthcare provider about the risks and benefits of
    breastfeeding and about the best way to feed your baby while receiving
    ZULRESSO.

Tell your healthcare provider about all the medicines you take, including
prescription and over-the-counter medicines, vitamins, and herbal
supplements.

ZULRESSO and some medicines may interact with each other and cause
serious side effects.

Especially tell your healthcare provider if you take other
antidepressants, opioids, or Central Nervous System (CNS) depressants
(such as benzodiazepines).

Know the medicines you take. Keep a list of them to show your healthcare
provider and pharmacist when you get a new medicine. Your healthcare
provider will decide if other medicines can be taken with ZULRESSO.

How will I receive ZULRESSO?

ZULRESSO is given to you by continuous intravenous (IV) infusion into
your vein. The infusion will last for a total of 60 hours (2.5 days).

What should I avoid while receiving ZULRESSO?

  • ZULRESSO may make you feel dizzy and sleepy. Do not drive a car or do
    other dangerous activities after your ZULRESSO infusion until your
    feeling of sleepiness has completely gone away. See “What is the
    most important information I should know about ZULRESSO?
  • Do not drink alcohol while receiving ZULRESSO.

What are the possible side effects of ZULRESSO?

ZULRESSO can cause serious side effects, including:

  • See “What is the most important information I should know about
    ZULRESSO?
  • Increased risk of suicidal thoughts or actions. ZULRESSO and
    other antidepressant medicines may increase suicidal thoughts and
    actions in some people 24 years of age and younger. Depression or
    other serious mental illnesses are the most important causes of
    suicidal thoughts or actions.

How can I watch for and try to prevent suicidal thoughts and actions?

  • Pay close attention to any changes, especially sudden changes in mood,
    behavior, thoughts, or feelings, or if you develop suicidal thoughts
    or actions.
  • Tell your healthcare provider right away if you have any new or sudden
    changes in mood, behavior, thoughts, or feelings.
