Indivior’s NALSCUE® Receives Marketing Authorization from French Regulatory Agency ANSM

French Regulatory Agency ANSM Approves Marketing Authorisation for Indivior’s NALSCUE® (Naloxone Hydrochloride) Nasal Spray for the Emergency Treatment of Characterized or Suspected Opioid Overdose

Ready-to-use, Needle-free Device Can Temporarily Reverse Characterized or Suspected Opioid Overdose Within Minutes1

Slough, UK, 31 July 2017 – Indivior Inc., a subsidiary of Indivior PLC (LON: INDV), today announces that l’Agence Nationale de Sécurité du Médicament et des produits de santé (ANSM) has approved a Marketing Authorisation (MA) in France for Indivior’s NALSCUE® Nasal Spray for the emergency treatment of characterized or suspected opioid overdose, evidenced by respiratory depression, pending treatment in a medical department. NALSCUE® has been provided in France under a Temporary Authorisation for Use (Autorisation Temporaires d’Utilisation or ATU) since July 2016.

NALSCUE® is a ready-to-use, needle-free, disposable delivery system that is designed to deliver a dose of naloxone through the nasal mucosa of an opioid overdose victim and allows for rapid administration of the rescue medication. NALSCUE® is supplied as a preassembled device that requires minimal training so that a layperson can administer treatment to a characterized or suspected opioid overdose victim prior to the arrival of the emergency medical services.1,2

Naloxone is an opioid receptor antagonist that effectively reverses the effects of natural and synthetic opioids for a period of time.2 Naloxone, through injectable administration, has been used for opioid overdose treatment for over 40 years. It is widely used by hospitals and emergency medical service personnel.3,4 NALSCUE® is the first MA approved intranasal naloxone product for the emergency treatment of characterized or suspected opioid overdose in France.

“As opioid overdoses continue to have a profound impact on communities within France, NALSCUE® may help make every second count by potentially allowing anyone, not just medical professionals, to administer life-saving treatment at the scene of an overdose,” said Ponni Subbiah, MD, MPH, Chief Medical Officer of Indivior.

About NALSCUE® Nasal Spray

NALSCUE® (naloxone hydrochloride) Nasal Spray is indicated for the emergency treatment of characterized or suspected opioid overdose in adults and children older than 1 month, evidenced by respiratory depression and pending treatment in a medical department.

The use of NALSCUE® is not a substitute for emergency care by a medical department.

NALSCUE® is an emergency treatment and it should be ensured that the patient understands the importance of medical management after the use of this medication. Patients at risk for opioid overdose and his/her family who may administer NALSCUE® must receive clear instructions on the use of the medication. The emergency services should be called immediately as a matter of course before administering NALSCUE® and the patient should be monitored until the emergency services arrive.

The duration of some opioids may be longer than that of naloxone leading to a probable risk of recurrence of respiratory depression, even after an initial improvement in symptoms. In subjects who have consumed opioids, the sudden and complete reversal of their effects by naloxone may trigger the onset of major withdrawal syndrome. This emphasizes the continued need for medical management even after administration of NALSCUE®.

The following side effects have been reported after the administration of NALSCUE®: Changes to taste, headache, tactile sensitivity disorders, change to sense of smell and nasal congestion.
