Treatment-Resistant Depression Clinical Landscape Report 2026: Trials, Readouts and White Space
Turn fragmented clinical intelligence into a decision-ready landscape. This report was assembled with PatSnap MCP Servers for Clinical Trials, Drug & Asset, and Company & Deal Intelligence. Explore the PatSnap MCP Marketplace to reproduce the workflow in your own AI research stack.
Data snapshot: 16 July 2026. This report is a strategic research view, not medical advice. Trial status and timing can change; confirm records before making development or investment decisions.
Executive view
Treatment-Resistant Depression remains an active clinical development field. The field is increasingly separating symptomatic benefit from disease modification, while enrichment, digital measures and fluid or imaging biomarkers reshape trial design. The PatSnap evidence set used here contains 284 matched trial records and 134 indexed result records before the decision-focused sample below was selected.
How PatSnap MCP built this report
The workflow used Clinical Trials MCP search to define the landscape, then clinical_trial_fetch to retrieve trial design, phase, status, sponsor, geography, endpoints and timing. It separately called clinical_trial_result_fetch for indexed readouts. Drug & Asset drug_fetch supplied target and global development status, while Company & Deal Intelligence organization_fetch supplied sponsor context. This keeps trial-, asset- and company-level claims distinct and traceable.
Trial landscape table
| Trial | Asset / intervention | Phase / status | Sponsor | Geography | Primary endpoint | Expected readout |
|---|---|---|---|---|---|---|
| NCT07696871 | Cannabidiol | Phase 1/2; Recruiting | Universidade Do Sul De Santa Catarina | Brazil | Change in Depressive Symptom Severity Assessed by the Hamilton Depression Rating Scale (HAM-17) (Baseline, Week 4, and Week 12) | 2026-12-31 |
| ChiCTR2600127836 | Intervention not normalized | Not Applicable; Not yet recruiting | Sponsor not listed | China | Assessment of Depressive Symptoms (Baseline, Day 5 post-treatment, Month 1 post-treatment, and Month 3…) | 2028-04-30 |
| NCT07680140 | Ketamine Hydrochloride | Phase 4; Not yet recruiting | Weill Medical College of Cornell University | United States | Change from Baseline to 2-Week Post-Intervention Score in Hamilton Depression Rating Scale (HDRS) Score (Baseline to 2-weeks post-intervention) | 2028-09-01 |
| NCT07673913 | Intervention not normalized | Not Applicable; Not yet recruiting | Sponsor not listed | Turkey | Change in Hamilton Depression Rating Scale (HAM-D-17) Total Score (Baseline and Week 4) | 2027-09-01 |
The table is designed for competitive decisions: endpoint selection, geographic reach and readout timing appear beside phase and sponsor. Phase alone does not reveal evidence maturity; a small study may answer a near-term biomarker question while a large pivotal program can leave a multi-year readout gap.
What indexed results say
- Augmentation Versus Switch: Comparative Effectiveness Research Trial for Antidepressant Incomplete and Non-responders With Treatment Resistant Depression (ASCERTAIN-TRD) (Phase 4): the indexed record reports -; MADRS(Mean) = -17.39 points (Standard Error, 1.3); -.
- GH001 vs Placebo in Patients With Treatment-Resistant Depression (Phase 2): the indexed record reports remission(day 8) = 23.0 Pts.
- Precision Targeting of Propofol-induced Electroencephalographic Slow Waves: a Novel Phase I Paradigm for Treatment-resistant Major Depressive Disorder (Phase 1): the indexed record reports Number of Participants Without Serious Adverse Events During Propofol Infusions = 16 Participants; -; -.
Cross-trial comparisons require caution. Population, prior therapy, baseline risk, endpoint definition, follow-up and analysis set can all change the apparent signal. The strategic value lies in identifying what each readout resolves—and which uncertainty remains.

Asset and sponsor context
PatSnap Drug & Asset records add mechanism and global development status for the sampled programs, including Cannabidiol (Approved), Ketamine Hydrochloride (Approved; NMDA receptor). Company & Deal Intelligence records identify sponsor context for Universidade Do Sul De Santa Catarina, Weill Medical College of Cornell University. Together, those layers show whether a study sits inside a scaled portfolio, an emerging specialist strategy or an academic development path.
Where the white space is
- Validated biomarkers that bridge biological activity to meaningful function.
- Longer follow-up that distinguishes transient symptom change from altered disease trajectory.
- Decentralized and digital measures that reduce noise without increasing patient burden.
- Trials designed around genetically or biologically defined subgroups.
Strategic implications
For sponsors, differentiation is more credible when the evidence package resolves a known decision gap: an active comparator, a better-defined responder population, a safer or easier delivery model, a clinically meaningful outcome, or a defensible sequencing strategy. Business-development teams can use the same landscape to separate crowded mechanisms from differentiated evidence architectures. Investors should track endpoint maturity and operational feasibility alongside nominal phase.
What to monitor next
Track status changes, protocol amendments, primary-completion dates, newly indexed results, ownership changes and multinational expansion. Re-run the MCP queries on a schedule and compare deltas. Pay particular attention when a program moves from a surrogate endpoint to a clinical outcome or when a specialist sponsor adds a scaled development partner.
Bottom line
Treatment-Resistant Depression has meaningful clinical activity and equally meaningful evidence gaps. A useful landscape connects trial design, results, mechanism and sponsor rather than listing studies in isolation.
