Lysozyme Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Lysozyme 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 date: 24 July 2026. Currency fields are presented in US$ millions as returned by the deal dataset. This is a screening memorandum, not legal, medical, patent or investment advice.
Executive recommendation: GO
Decision memo
Advance diligence: development maturity and available evidence support continued investment, subject to indication-specific safety, IP, and commercial gates.
The central underwriting question is whether Lysozyme can convert its Chemical drugs profile and Peptidoglycan biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | Lysozyme (query alias: Lysozyme) |
|---|---|
| Modality / target | Chemical drugs; Peptidoglycan; Peptidoglycan inhibitors, Cell wall inhibitors |
| Highest global status | Approved |
| Originator | Shenyang Xingqi Pharmaceutical Co., Ltd. |
| Active developers | Shenyang Xingqi Pharmaceutical Co., Ltd. |
The MCP disease footprint includes Blepharitis, Conjunctivitis, Corneal Ulcer. 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 |
|---|---|---|---|---|
| CTR20182475 | Not disclosed | 进行中 （尚未招募） | 240 | Not disclosed |
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
Evidence gap
The Clinical Trials MCP returned no matched public result record. This is a gating diligence gap, not evidence of failure.
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
Lysozyme addresses Blepharitis, Conjunctivitis, Corneal Ulcer. Commercial attractiveness rests on addressable biomarker-positive patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Chemical drugs—must demonstrate a benefit large enough to offset class-specific safety and operational costs.
The strongest market-validation signal in this screen is partner behavior: 28 matched transaction record(s) indicate that sophisticated counterparties have assigned strategic value to the asset or its rights. That does not establish net present value; probability of success, remaining R&D spend, royalties, cost sharing and territorial scope still need modeling.
5. Transaction precedent and economics
Transaction-scope note: No direct asset-specific transaction was returned. The table below shows target-level comparable: Peptidoglycan records as comparable precedents only.
| Date | Transaction | Phase at deal | Disclosed economics |
|---|---|---|---|
| 2026-04-23 | Apotex Completes Previously Announced Strategic Transaction with Cumberland Pharmaceuticals | Approved | Financial terms not disclosed |
| 2025-08-07 | CorMedix Completes Acquisition of Melinta Therapeutics, Raises Financial Guidance and Announces New Leadership Team | Approved | US$300.0M upfront; US$25.0M milestones; US$325.0M stated total |
| 2025-08-04 | Cumberland Pharmaceuticals Receives Vizient Contract For New Vibativ® 4-Vial Starter Pak | Approved | Financial terms not disclosed |
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 “Improved enzymosomes of lysozyme for ocular drug delivery”. The milestone feed surfaced a patent-application signal described as “Lysozyme preparation, preparation method thereof, and application thereof”.
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. Confirm that licensed patents, data and know-how track every granted territory and field.
7. Principal risks and diligence gates
- Class crowding and differentiation versus other PD-(L)1/VEGF agents
- Immune and anti-angiogenic safety, including bleeding and cardiovascular risk
- Biomarker strategy, indication selection, and head-to-head endpoint execution
Cross-functional diligence should also test CMC comparability, supply chain, pharmacovigilance, regulatory correspondence, data integrity, investigator concentration, partner obligations and change-of-control restrictions.
8. Final go/no-go memorandum
GO
Advance diligence: development maturity and available evidence support continued investment, subject to indication-specific safety, IP, and commercial gates.
Required pre-signing gates: reproduce key efficacy analyses; complete an indication-specific safety review; run a full patent-family and freedom-to-operate search; model risk-adjusted economics by territory; and reconcile all rights, sublicenses and encumbrances.
