Clinical TrialTreatment-Resistant Depression (TRD)EsketamineCompleted

A Long-term Safety Study of Esketamine Nasal Spray in Treatment-resistant Depression (SUSTAIN-3)

Open-label, long-term extension Phase III safety study (n≈1148) of esketamine nasal spray (flexible 28–84 mg dosing) in participants with treatment-resistant depression, induction twice weekly for 4 weeks then individualised maintenance.

Target Enrollment
1148 participants
Study Type
Phase III interventional
Design
Non-randomized

Detailed Description

This open-label extension evaluates the long-term safety and tolerability of esketamine nasal spray in participants with treatment-resistant depression who rolled over from prior phase trials.

Design includes a 4-week induction phase with twice-weekly flexible dosing (28, 56 or 84 mg depending on age and prior dosing), followed by an optimisation/maintenance phase with weekly or biweekly dosing determined by clinical judgement.

Primary assessments are safety and tolerability measures including adverse events, vital signs, ECG and laboratory monitoring; study enrolled participants from multinational sites.

Esketamine Nasal Spray

experimental

Open-label induction (twice weekly for 4 weeks, flexible dosing) followed by optimisation/maintenance (weekly or every-other-week dosing based on clinical judgement).

Interventions

  • Esketamine
    via Inhalation• twice per week (induction) then weekly or every other week (maintenance)

    Flexible dosing: 28, 56 or 84 mg depending on age and prior study dosing; participants <65 typically 56 or 84 mg, ≥65 start at 28 mg. Induction = twice weekly for 4 weeks (≈8 sessions); maintenance individualised after Week 4.

  • Participant must be medically stable on the basis of physical examination, vital signs, pulse oximetry, and 12-lead Electrocardiogram (ECG) performed predose on the day of the first intranasal treatment session. If there are any abnormalities that are not specified in the inclusion and exclusion criteria, their clinical significance must be determined by the investigator and recorded in the participant's source documents and initialed by the investigator
  • Participant must be medically stable according to the investigator's judgment and knowledge of the subject's medical stability in the parent study. This determination must be documented.
  • A woman of childbearing potential must have a negative serum (beta-human chorionic gonadotropin [b-hCG]) predose on the day of the first intranasal treatment session
  • During the study (that is, from the first intranasal treatment session) and for a minimum of 1 spermatogenesis cycle (defined as approximately 90 days) after receiving the last dose of intranasal study medication, a man who is sexually active with a woman of childbearing potential must be practicing a highly effective method of contraception with his female partner c) must agree not to donate sperm.

Exclusion Criteria

  • Exclusion Criteria:
  • The evaluation of the benefit versus risk of continued esketamine nasal spray treatment is not favorable for the participant in the opinion of the investigator
  • Since the last study visit in the participant's prior study, participant has suicidal ideation with intent to act per the investigator's clinical judgment or based on the Columbia Suicide Severity Rating Scale (C-SSRS) [corresponding to a response of "Yes" on Item 4 (active suicidal ideation with some intent to act, without specific plan) or Item 5 (active suicidal ideation with specific plan and intent) in the suicidal ideation module of the C-SSRS] or suicidal behavior per the investigator's clinical judgment or based on the C-SSRS (corresponding to any score higher than 0 in the suicidal behavior module of the C-SSRS)
  • Participant has positive test result(s) for drugs of abuse (including barbiturates, methadone, opiates, cocaine, phencyclidine, and amphetamine/methamphetamine) predose on the day of the first intranasal treatment session
  • Participant has any anatomical or medical condition that, per the investigator's clinical judgment based on assessment, may impede delivery or absorption of intranasal study drug
  • Participant has taken any prohibited therapies that would not permit administration of the first intranasal treatment session
