- Brief Summary
The purpose of this study is to assess whether the antidepressant effect from intravenous (IV) ketamine treatment can be maintained by minocycline compared to placebo after IV ketamine treatment is stopped.
- Detailed Description
This is a placebo-controlled (i.e., an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial), double-blind (neither physician nor patient knows the treatment that the patient receives) randomized (the drug is assigned by chance) study in patients with Major Depressive Disorder (MDD) and Bipolar Disorder Type II. The study is designed to assess whether the antidepressant response to treatment with intravenous (IV) ketamine can be maintained by treatment with minocycline in patients with MDD and Bipolar Depression Type II (compared to placebo). Both hospitalized patients as well as patients being treated as an outpatient for their current episode of depression can qualify for participation in this study. The study has four sequential phases: if eligibility for the study has been confirmed during the 21-day screening phase, the patients will enter a 12-day open-label (ie, patient and physician know the intervention that is being administered) treatment phase during which the patient will receive 6 open-label IV infusions of 0.5 mg/kg ketamine on Day 1, 3, 5, 8, 10 and 12 in combination with open-label minocycline, orally administered twice daily. All patients will remain at the study site for at least 4 hours after the IV ketamine administrations. Response to treatment will be assessed using the Montgomery-Asberg Depression Rating Scale (MADRS) which is designed to measure the overall severity of depressive symptoms. Patients responding to ketamine/minocycline treatment will be randomized to receive minocycline or placebo for 6 weeks during a 6-week blinded treatment phase or until relapse. A patient will be defined as a "ketamine responder" if there is a 50% or more decrease in comparison to baseline values (Day 1 predose) in the MADRS total score performed at 3 to 4 hours postdose on Days 8, 10, or 12, with a 40% or more decrease from baseline in the MADRS total score on Day 12. Patients not responding to treatment with ketamine/minocycline will be given the option to receive 100 mg minocycline twice daily as open-label treatment for a maximum of 6 weeks. The patients (both responders and non-responders) will have weekly visits following last dose of ketamine until Day 54 (responders/non-responders) or until relapse (responders) whichever comes first, to determine the duration of the antidepressant effect and to assess safety and tolerability after completion of treatment. Upon completion of the study (Day 54) or at time of relapse all patients will have an end-of-study visit. All patients can return to standard of care treatment at the end of the study. The total study duration for each patient will be maximally 11 weeks.

Group Intervention Description Placebo Placebo Following a 12-day open-label treatment phase (involving ketamine and minocycline), responders may receive placebo twice daily for up to 6 weeks in a blinded manner Ketamine and Minocycline Ketamine All patients will receive 6 IV infusions of ketamine and oral minocycline twice daily during a 12-day open-label treatment phase Ketamine and Minocycline Minocycline All patients will receive 6 IV infusions of ketamine and oral minocycline twice daily during a 12-day open-label treatment phase Minocycline Minocycline Following a 12-day open-label treatment phase (involving ketamine and minocycline), responders may receive oral minocycline twice daily for up to 6 weeks in a blinded manner. In addition, non-responders may receive oral minocycline twice daily for up to 6 weeks in an open-label manner.
- Primary Outcome Measures
Name Time Method Proportion of patients (among responders) who survive relapse-free Day 54 The Montgomery-Asberg Depression Rating Scale (MADRS) measures depression severity and detects changes due to antidepressant treatment. The test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe condition. Relapse is defined as MADRS ≥ 30.

The test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe condition.
