Report scope. This 2026 Drug Asset Due Diligence Report evaluates SG-1 as a potential licensing, partnership, acquisition, or option asset. The review separates verified evidence from open diligence questions across clinical development, intellectual property, market positioning, and transaction precedent.
Executive recommendation: HOLD / OPTION
SG-1 is a Small molecule drug associated with DHODH and a global highest development stage of Phase 2. The lead disclosed indication is Invasive Fungal Infections. The current evidence supports a HOLD / OPTION posture, subject to confirmation of study-level data, ownership, patent coverage, manufacturing readiness, and regional rights.
Decision memo
- Asset: SG-1
- Target: DHODH
- Lead indication: Invasive Fungal Infections
- Highest phase: Phase 2
- Matched trials: 3
- Matched result records: 0
- Matched asset deals: 1

1. Asset identity and development status
The first diligence task is entity resolution. Teams should reconcile development codes, nonproprietary names, salts, formulations, combinations, sponsors, and predecessor owners before relying on portfolio counts. For SG-1, the MCP profile identifies DHODH as the primary target context and Invasive Fungal Infections as the lead indication. Global phase labels are useful orientation points, but investment decisions require country- and indication-level status verification.
Confirm the exact molecule, formulation, route, dose, biomarker definition, and current sponsor. Review discontinuations separately from active development so that an historical high phase is not mistaken for a live program.

2. Clinical program: design and endpoint audit
| Registry | Phase | Status | Enrollment | Lead primary endpoint |
|---|---|---|---|---|
| JPRN-UMIN000058345 | Not Applicable | /Completed | Not disclosed | Not disclosed |
| CTR20252293 | Phase 2 | （） | 60 | Not disclosed |
| CTR20243633 | Phase 1 | Status not disclosed | 76 | Not disclosed |
The clinical program should be audited for randomization, comparator relevance, dose selection, endpoint hierarchy, multiplicity, analysis population, geographic mix, and readout timing. Early-stage programs require attention to pharmacokinetics, pharmacodynamics, adverse events, dose-limiting toxicities, and the rationale for the expansion dose.

3. Clinical readouts: what is known
No exact asset-specific result record was returned. The absence of a matched indexed readout is a diligence gap, not evidence of negative efficacy.
For every reported endpoint, obtain the protocol, statistical analysis plan, patient disposition, baseline characteristics, subgroup definitions, exposure duration, and full safety tables. Conference abstracts and registry summaries can support screening, but they should not replace source data review in a binding transaction.

4. Market and competitive position
The commercial case depends on differentiated efficacy, tolerability, convenience, biomarker reach, treatment setting, and access. A target-level market may be attractive while an individual asset remains undifferentiated. Benchmark SG-1 against approved therapies and clinical competitors in Invasive Fungal Infections, including likely standards of care at the expected launch date.
Build a scenario model around addressable patients, diagnosis and biomarker rates, line of therapy, duration, net price, uptake, displacement, combination costs, and probability-adjusted timelines. Test slower enrollment, delayed readout, narrower labels, safety restrictions, and competitor launches.

5. Transaction precedent and economics
| Date | Transaction | Status | Type | Disclosed value |
|---|---|---|---|---|
| 2024-06-04 | 1SG1001 | Active | License | Not disclosed |
Transaction records should be normalized for territory, asset scope, phase at signing, option mechanics, development obligations, cost sharing, royalties, milestones, and change-of-control terms. Undisclosed economics must not be converted into invented benchmarks.
6. IP and freedom-to-operate screen
Complete a family-level patent review covering composition of matter, sequence or construct claims, polymorph and salt claims, formulation, dosing, combinations, biomarkers, manufacturing, and method of use. Verify priority, ownership, assignments, prosecution status, term adjustments, extensions, oppositions, and regional coverage. Freedom to operate is a separate legal analysis and should include competitor claims and platform dependencies.
The diligence room should reconcile inventorship, employee and contractor assignments, university or platform licenses, sublicensing restrictions, government rights, and obligations triggered by development milestones or commercialization.

7. Principal risks and diligence gates
- Identity risk: resolve all aliases, formulations, combinations, and owners.
- Clinical risk: confirm source data, protocol deviations, endpoint definitions, and safety follow-up.
- Regulatory risk: review agency correspondence, meeting minutes, holds, commitments, and indication-specific pathways.
- IP risk: validate enforceable coverage, remaining life, ownership, and freedom to operate.
- CMC risk: assess process control, analytical methods, comparability, scale-up, supply, and cost of goods.
- Commercial risk: pressure-test differentiation, market access, competitive timing, and realistic adoption.
- Transaction risk: map rights, encumbrances, royalties, options, consent requirements, and change-of-control provisions.
8. Final go/no-go memorandum
HOLD / OPTION
Proceed only through staged diligence. Before exclusivity or a binding offer, require a verified asset identity package, complete clinical data room, regulatory correspondence, patent-family schedule, freedom-to-operate opinion, CMC package, ownership chain, regional rights map, and risk-adjusted valuation. Any material mismatch between public records and source documents should pause the process until reconciled.
