Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults diagnosed with major depressive disorder who have not responded to at least two prior antidepressant treatments.
✕Probably not a fit
Patients with severe psychiatric disorders such as schizophrenia or bipolar disorder will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This open-label, multi-centre Phase 2a study aims to assess the safety, tolerability, and pharmacodynamics of BPL-003, an intranasal treatment, in patients with treatment resistant depression. The study consists of two parts: the first part involves administering one of two single doses of BPL-003 to patients, while the second part involves two doses, both accompanied by psychological support. Participants will be monitored for 12 weeks in Part 1 and 10 weeks in Part 2 to evaluate the treatment's effects. The study includes patients who have not responded adequately to previous antidepressant therapies.
Why it matters
Potential benefit: If successful, this treatment could provide a new option for patients suffering from treatment resistant depression.
How similar studies have gone: Other studies exploring novel treatments for treatment resistant depression have shown promise, indicating potential for success with this approach.

Diagnosed with TRD defined as failure to respond to an adequate dose and duration of at least 2 pharmacological treatments in the past 5 years prior to screening, at least one of which is during the current episode. 3. Montgomery-Asberg Depression Rating Scale score ≥24 at Screening. 4. Clinical Global Impression - Severity ≥4 at Screening. 5. Willing and able to discontinue current pharmacological anti-depressant therapy. 6. On current stable dose of pharmacological antidepressant therapy limited to one of 4 SSRIs (Arm B), i.e. either citalopram, escitalopram, sertraline or fluoxetine. Exclusion Criteria: 1. Current or history of schizophrenia, psychotic disorder including psychotic depression, bipolar disorder, delusional disorder, schizoaffective disorder, or any other severe psychiatric disorder. 2. Current personality disorders. 3. First-degree family history of schizophrenia, bipolar disorder, delusional disorder, personality disorders or schizoaffective disorder. 4.

Suicidal ideation with the intent to act or suicidal behaviour within the 12 months prior to the start of Screening or on Day 1 prior to dosing. 7. Suicide attempt and/or self-injurious behaviour within the last 12 months prior to Screening. 8. Uncontrolled medical conditions e.g. hypo/hyperthyroidism, diabetes, renal failure. 9. Seizure disorder or history of seizures (including febrile seizures). 10. Abnormal and clinically significant results on the physical examination, vital signs, electrocardiogram, or laboratory tests at Screening Baseline. 11. Any nasal obstruction, blockage, or symptoms of congestion at the time of dosing, that in the Investigator's opinion may interfere with administration of the study drug. 12. Currently receiving lithium, antipsychotics, serotonergic drugs (excluding the permitted SSRIs for arm B), psychostimulants, or any other prohibited medication. 13. Female patients who are pregnant or lactating, or of childbearing potential and not willing to use adequate forms of contraception. 14.
