Clofutriben Drug Asset Due Diligence Report 2026

This Clofutriben Drug Asset Due Diligence Report was built with PatSnap Life Sciences MCP workflows. Drug & Asset MCP establishes identity, ownership and stage; Clinical Trials MCP checks design, endpoints and readouts; Company & Deal Intelligence MCP reconstructs transaction precedent.

Decision memo

Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.

The central underwriting question is whether Clofutriben can convert its Small molecule drug profile and 11β-HSD1 biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.

1. Asset identity and development status

Asset	Clofutriben (query alias: Clofutriben)
Modality / target	Small molecule drug; 11β-HSD1; 11β-HSD1 inhibitors
Highest global status	Phase 2
Originator	Sparrow Pharmaceuticals, Inc.
Active developers	Sparrow Pharmaceuticals, Inc.

The MCP disease footprint includes Diabetes Mellitus, Type 2, Acrocallosal Syndrome, Acth-Independent Macronodular Adrenal Hyperplasia. The highest-phase flag is a useful orientation point, but the licensing case depends on indication-level evidence and rights, not the global label alone.

2. Clinical program: design and endpoint audit

Registry	Phase	Status	Enrollment	Lead primary endpoint
NCT07296484	Phase 2	Recruiting	1500	Primary endpoint not disclosed in English source
NCT07227922	Phase 1	Recruiting	16	Primary endpoint not disclosed in English source
NCT07226635	Phase 1	Completed	16	Primary endpoint not disclosed in English source

The trial set should be diligenced for randomization, comparator relevance, endpoint hierarchy, analysis population, multiplicity, geographic mix and readout timing. For early-stage studies, safety and dose selection can be as decision-critical as response rate.

3. Clinical readouts: what is known

1807-P: Cardiometabolic Effects of Clofutriben (CLO) in Adults with Type 2 Diabetes (T2D): A Six-Week, Phase 2, Placebo-Controlled, Randomized Clinical Trial

Phase 2; n=98; evaluation: Positive. Reported fields: Cholesterol = 1.0 mg/dL ; DBP = 2.0 mmHg

Sparrow Pharmaceuticals Presented New Data on Clofutriben and Prednisolone for Polymyalgia Rheumatica Treatment at DGRh Kongress 2024

Phase 2; n=40; evaluation: Positive. Reported fields: Efficacy = A combination of prednisolone 20 mg with clofutriben showed similar efficacy as prednisolone 10 mg with placebo, based on analysis of participants’ symptoms, physical function, and biomarkers of inflammation. ; Efficacy = A combination of prednisolone 20 mg with clofutriben showed similar efficacy as prednisolone 10 mg with placebo, based on analysis of participants’ symptoms, physical function, and biomarkers of inflammation.

Sparrow Pharmaceuticals Presents Data from Ongoing Phase 2 Trial of Clofutriben (SPI-62) and Prednisolone as a Treatment for Polymyalgia Rheumatica at EULAR 2024

Phase 2; n=not disclosed; evaluation: Positive. Reported fields: Efficacy = Prednisolone 10mg combined with clofutriben 6mg demonstrated less efficacy compared to prednisolone 10mg administered with placebo, Prednisolone 20mg combined with clofutriben 6mg demonstrated similar efficacy as determined by symptoms, physical function, and systemic inflammation, ; Efficacy = Prednisolone 10mg combined with clofutriben 6mg demonstrated less efficacy compared to prednisolone 10mg administered with placebo, Prednisolone 20mg combined with clofutriben 6mg demonstrated similar efficacy as determined by symptoms, physical function, and systemic inflammation,

These fields are structured evidence signals, not a substitute for statistical review. The next diligence pass should reconcile denominators, confidence intervals, follow-up, censoring, dose cohorts and treatment-emergent toxicity against the original abstract, registry and protocol.

4. Market and competitive position

Clofutriben addresses Diabetes Mellitus, Type 2, Acrocallosal Syndrome, Acth-Independent Macronodular Adrenal Hyperplasia. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Small molecule drug—must demonstrate a benefit large enough to offset class-specific safety and operational costs.

The MCP screen returned matched transaction record(s) under the scope “target-level comparable: 11β-HSD1.” Partner activity is a market-validation signal, but it does not establish net present value.

5. Transaction precedent and economics

Transaction-scope note: No direct asset-specific transaction was returned. The table below shows target-level comparable: 11β-HSD1 records as comparable precedents only.

Date	Transaction	Phase at deal	Disclosed economics
No matched asset or comparable transaction returned.

Headline values are not directly comparable. Diligence should normalize upfront cash, equity, development and sales milestones, tiered royalties, opt-in mechanics, cost sharing, change-of-control clauses and geography.

6. IP and freedom-to-operate screen

The milestone feed surfaced a patent-application signal described as “Methods and compositions for treating glucocorticoid-mediated diseases”. The milestone feed surfaced a patent-application signal described as “Methods and compositions for treating HSD-1-mediated disorders”. The milestone feed surfaced a patent-application signal described as “Methods and compositions for treating glucocorticoid excess”.

The claim chart should separately test composition or sequence coverage, formulation and dosing, indication and biomarker claims, combinations, manufacturing know-how, prosecution history, term extensions and third-party blocking rights.

7. Principal risks and diligence gates

Therapeutic index and off-target toxicity
Resistance biology and biomarker-defined patient selection
Differentiation from established and emerging standards

Cross-functional diligence should also test CMC comparability, supply chain, pharmacovigilance, regulatory correspondence, data integrity, investigator concentration, partner obligations and change-of-control restrictions.
