OCDC vaccine(Sichuan University) Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This OCDC vaccine(Sichuan University) 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. Explore the MCP servers used in this report.
Decision date: 16 September 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: CONDITIONAL GO
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 OCDC vaccine(Sichuan University) can convert its Therapeutic vaccine, Dendritic cell vaccine profile and Not disclosed biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | OCDC vaccine(Sichuan University) (query alias: OCDC vaccine(Sichuan University)) |
|---|---|
| Modality / target | Therapeutic vaccine, Dendritic cell vaccine; Not disclosed; Immunostimulants |
| Highest global status | Phase 2 |
| Originator | Sichuan University |
| Active developers | Sichuan University |
The MCP disease footprint includes Esophageal Squamous Cell Carcinoma, Locally Advanced Esophageal Squamous Cell Carcinoma, Unresectable Esophageal Squamous Cell Carcinoma. 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 |
|---|---|---|---|---|
| NCT06675201 | Phase 2 | Recruiting | 165 | Primary endpoint not disclosed in English source |
| NCT05317325 | Phase 1 | Not yet recruiting | 20 | Primary endpoint not disclosed in English source |
| NCT05235607 | Phase 1 | Unknown status | 60 | 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
Safety and feasibility of personalized neoantigen DC vaccines in postoperative esophagus squamous cell carcinoma: A Phase 1b trial
Phase 1; n=12; evaluation: Positive. Reported fields: AE(All-grade) = 5 Pts ; mDFS = NR
Personalized neoantigen pulsed dendritic cell vaccine for advanced lung cancer
Phase 1; n=12; evaluation: Positive. Reported fields: ORR = 25 %
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
OCDC vaccine(Sichuan University) addresses Esophageal Squamous Cell Carcinoma, Locally Advanced Esophageal Squamous Cell Carcinoma, Unresectable Esophageal Squamous Cell Carcinoma. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Therapeutic vaccine, Dendritic cell vaccine—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 “asset-specific.” Partner activity is a market-validation signal, but it does not establish net present value.
5. Transaction precedent and economics
| 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
No asset-specific patent-application milestone appeared in the returned milestone slice. That absence is not a freedom-to-operate conclusion; a dedicated family, claim, ownership, expiry, and legal-status search remains mandatory before signing.
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
- Immunogenicity durability and clinically meaningful protection
- Population selection, endpoint timing, and comparator relevance
- Manufacturing consistency, distribution, and uptake
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
CONDITIONAL GO
Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.
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.
