Heart Failure with Reduced Ejection Fraction 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
Heart Failure with Reduced Ejection Fraction remains an active clinical development field. Development is moving beyond single surrogate measures toward integrated cardiometabolic, renal and clinical-outcome evidence, with convenience and persistence becoming major differentiators. The PatSnap evidence set used here contains 277 matched trial records and 124 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 |
|---|---|---|---|---|---|---|
| NCT07702760 | Intervention not normalized | Not Applicable; Not yet recruiting | Sponsor not listed | Geography not listed | The prescription level (%) of GDMT / 4 pillars in de novo HFrEF patients. (1 year of follow-up) | 2029-06-01 |
| NCT07697833 | Vericiguat | Phase 4; Not yet recruiting | NICVD | Geography not listed | Quality of life using Kansas City Cardiomyopathy Questionnaire (KCCQ-12) (Baseline to Month 6) | 2027-05-15 |
| NCT07696975 | Intervention not normalized | Not Applicable; Not yet recruiting | V-Wave Ltd. | Geography not listed | Primary Safety (From enrollment at the intervention procedure through 30 days.); Primary Effectiveness (The Primary analysis will be conducted after the final enrolled participant…) | 2029-03-31 |
| NCT07695090 | Lumacaftor | Phase 2; Recruiting | Sponsor not listed | Canada | Efficacy of lumacaftor treatment in increasing cerebral blood flow versus placebo in HFrEF patients. (Baseline and 1 month) | 2027-05-01 |
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
- Heart Failure Patients With Left Ventricular Assist Devices Being Treated With Sodium-Glucose Co-Transporter 2 Inhibitors (Phase 4): the indexed record reports Change in Left Ventricular End-diastolic Dimension (LVEDD)(Median) = -1.1 centimeters (cm) (Inter-Quartile Range, -2.4 to -0.4); Change in Left Ventricular End-diastolic Dimension (LVEDD)(Median): P-Value = 0.38; Change in Left Ventricular End-diastolic Dimension (LVEDD)(Median): P-Value = 0.38.
- Open-Label Rollover Study of Levosimendan in Patients With Pulmonary Hypertension With Heart Failure and Preserved Left Ventricular Ejection Fraction (PH-HFpEF) (Phase 2): the indexed record reports Clinical Safety = 33 Participants; -; -.
- The Effect of Vericiguat on Endothelial Function in Patients with Heart Failure with Reduced Ejection Fraction: A Pilot Randomized Study (Phase 2): the indexed record reports FMD: Difference (%) = 0.7(95.0% CI, -1.1 to 2.5), P-Value = 0.4; FMD: Difference (%) = 0.7(95.0% CI, -1.1 to 2.5), P-Value = 0.4.
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 Vericiguat (Approved; sGC), Lumacaftor (Preclinical; CFTR). Company & Deal Intelligence records identify sponsor context for NICVD, V-Wave Ltd.. 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
- Active-comparator trials on top of contemporary standard of care.
- Hard cardiovascular, kidney or liver outcomes linked to earlier biomarker change.
- Evidence in underrepresented populations and patients with multiple comorbidities.
- Durability, adherence and post-discontinuation outcomes.
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
Heart Failure with Reduced Ejection Fraction 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.
