Brief Summary
Major depressive disorder (MDD) is a significant public health problem and leading cause of worldwide disability. Treatment resistance is common in MDD, however, for these individuals, targeted noninvasive brain stimulation is an alternative. Repetitive transcranial magnetic stimulation (rTMS) and more recently, theta-burst stimulation (TBS), are the noninvasive brain stimulation modalities with the largest evidence base in MDD. Although efficacious, an unacceptable proportion of patients do not significantly improve, and several aspects of the TMS parameter space are under investigation to enhance clinical outcomes. DCS has been shown in a randomized trial of more than double the percent response and remission from traditional TMS. When the AMPA one day (ONE-D) TMS protocol was combined with DCS, the measured response rate was 87% at one week. This trial will compare response and remission at six weeks following Transcranial Magnetic Stimulation + D-cycloserine vs. TMS+placebo.

Eligibility Criteria
You may qualify if:
- to 65 years of age, inclusive, at Screening.
- Scheduled for Transcranial Magnetic Stimulation by a treating physician.
- Able to understand and provide written and dated informed consent prior to Screening.
- Deemed likely to comply with the study protocol, including communication of adverse events (AEs) and other clinically important information, including adherence to the text messaging component of the trial.
- Will follow medical directions for psychiatric care, as appropriate, per the standard of care.
- Resides in a stable living situation. A stable living situation will be defined as a minimum of 3 months at the same address with a reasonable expectation that the situation will continue such that the patient's ability to participate in the study will not be affected. Please note that housing in a shelter of any kind will not be deemed stable housing.
- Previously diagnosed with treatment-resistant depression according to the criteria defined in the DSM-V and having failed treatment with at least two Selective Serotonin Reuptake Inhibitor (SSRI) drugs.
- Has an identified reliable informant/care partner that is willing to provide information and/or supportive care as necessary.
- No active suicidality (without the intention to act) as evidenced by a score of 3 or less on the Columbia Suicide Severity Rating Scale.
- A total score greater than or equal to 25 on the 10 items of the MADRS.
- No co-morbidities as ascertained by medical history, physical examination (including measurement of vital signs), clinical laboratory evaluations, and electrocardiogram (ECG) which might interfere with compliance or the ability to assess efficacy or safety.
- If female, a status of non-childbearing potential or use of an acceptable form of birth control per the following criteria, and agrees to continue use of the same method of birth control for the duration of study participation:
- a. Non-childbearing potential: physiologically incapable of becoming pregnant (i.e., permanently sterilized \[status post-hysterectomy, bilateral tubal ligation\], or post-menopausal with last menses at least one year prior to Screening); or b. Childbearing potential, and meets the following criteria: i. Use of any form of hormonal birth control for at least 2 months prior to Screening, on hormone replacement therapy that started prior to 12 months of amenorrhea, using an intrauterine device (IUD) for at least 1 month prior to Screening, in a monogamous relationship with a partner who has had a vasectomy, or sexually abstinent.
- ii. Negative urinary pregnancy test at Screening, confirmed by a second negative urinary pregnancy test at Day 1, prior to receiving study treatment.
- Body mass index (BMI) between 18-40 kg/m2; BMI up to 45 kg/m2 is allowed with Medical Monitor review and approval.
- +4 more criteria
You may not qualify if:
- <!-- -->
- Female of childbearing potential who is not willing to use one of the specified forms of birth control during the study.
- Female who is pregnant or breastfeeding.
- Female with a positive pregnancy test at Screening or prior to randomization.
- Current DSM-5 diagnosis of moderate or severe substance use disorder (except marijuana or tobacco use disorder) within the 12 months prior to Screening. (Note: Substance use disorder cannot be the precipitant for study entry).
- A lifetime history of
- phencyclidine (PCP)/ketamine drug abuse, or
- failed use of ketamine for depression or suicidality.
- History of schizophrenia or schizoaffective disorder, or any history of psychotic symptoms when not in an acute bipolar mood episode.
- History of anorexia nervosa, bulimia nervosa, eating disorder not otherwise specified (NOS), or other specified feeding and eating disorders (OSFED) within 3 years of Screening.
- Has dementia, delirium, amnestic, or any other cognitive disorder.
- Current major psychiatric disorder, diagnosed at Screening with the MINI 7.0.2 which is the primary focus of treatment, with bipolar disorder as the secondary focus of treatment, within the past 6 months.
- Estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73 m2 using the Cockcroft-Gault formula.
- A clinically significant abnormality on the Screening physical examination that may affect safety or study participation, or that may confound interpretation of study results according to the study clinician.
