Summary

This study tests whether adding a drug called NRX-101 (a mix of D-cycloserine and lurasidone) to transcranial magnetic stimulation (TMS) helps people with treatment-resistant depression more than TMS alone. About 400 adults who have not had TMS before will receive either the drug or a placebo alongside a one-day TMS session. Researchers will measure depression and suicidal thoughts after six weeks to see if the combination improves outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
NRX-101 (D-cycloserine and lurasidone)
What this could lead to
If successful, this could provide a more effective treatment option for people with treatment-resistant depression, potentially doubling response and remission rates compared to TMS alone.
What could go wrong
This is an early-stage trial (Phase 2/3) with 400 participants, so results may not apply to everyone. The combination drug may cause side effects, and the placebo group also receives TMS, so the added benefit of NRX-101 is uncertain.

Has treatment-resistant MDD defined as failure to achieve an adequate response after at least two adequate antidepressant trials of different agents, each given at a therapeutic dose and for sufficient duration. 7. A total score ≥ 25 on the 10 items of the MADRS. 8. Has an identified reliable informant/care partner that is willing to provide information and/or supportive care as necessary. 9. If heterosexual 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: 1.

Childbearing potential, and meets the following criteria: i. Must agree to use at least one highly effective method of birth control (methods which result in a failure rate of less than 1% per year when used consistently and correctly) during study participation. Examples of acceptable highly effective methods include established use of oral, injected, implanted, or intrauterine hormonal contraception; placement of an intrauterine device or intrauterine system; or a vasectomized partner with documented azoospermia; or true sexual abstinence that is the participant's usual and preferred lifestyle. ii. Negative urinary pregnancy test at Screening, confirmed by a second negative urinary pregnancy test at Day 1, prior to receiving study treatment. 10. Body mass index (BMI) between 18-40 kg/m2; BMI up to 45 kg/m2 is allowed with Medical Monitor review and approval. 11. If receiving concurrent psychotherapy, the type and frequency of the therapy (e.g., weekly or monthly) has been stable for at least 3 months prior to Screening and will remain stable for the duration of study participation. 12. Concurrent hypnotic therapy (e.g., with zolpidem, zaleplon, melatonin, benzodiazepines, maximum 2 mg daily, or trazodone) will be allowed if the therapy has been stable for at least 4-weeks prior to screening and will remain stable during the course of the patient's participation in the study. 13. Concurrent treatment with benzodiazepines is allowed up to a maximum dose 2 mg/daily used for anxiety if therapy has been stable relative to dose and schedule for at least 4 weeks prior to screening and if it is expected to remain stable during the course of the patient's participation in the study. Exclusion criteria: A patient is ineligible for inclusion in this study Heterosexual female of childbearing potential who is not willing to use one of the specified forms of birth control during the study. 2. Female who is pregnant (positive pregnancy test at Screening) or breastfeeding. 3. Active suicidality (without the intention to act) as evidenced by a score of \>3 on the Columbia Suicide Severity Rating Scale. 4.
