Recombinant annexin A5 (Annexin Pharmaceuticals) Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Recombinant annexin A5 (Annexin Pharmaceuticals) 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: 18 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: HOLD / OPTION
Decision memo
Preserve optionality until clinical differentiation, transaction economics, and freedom-to-operate are sufficiently de-risked.
The central underwriting question is whether Recombinant annexin A5 (Annexin Pharmaceuticals) can convert its Recombinant protein profile and ANXA5 biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | Recombinant annexin A5 (Annexin Pharmaceuticals) (query alias: Recombinant annexin A5 (Annexin Pharmaceuticals)) |
|---|---|
| Modality / target | Recombinant protein; ANXA5; ANXA5 modulators |
| Highest global status | Phase 2 |
| Originator | Annexin Pharmaceuticals AB |
| Active developers | Annexin Pharmaceuticals AB |
The MCP disease footprint includes Nonproliferative diabetic retinopathy, Retinal Vein Occlusion. 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 |
|---|---|---|---|---|
| NCT07259928 | Phase 2 | Recruiting | 12 | Primary endpoint not disclosed in English source |
| NCT05532735 | Phase 2 | Completed | 16 | Primary endpoint not disclosed in English source |
| NCT04850339 | Phase 1 | Completed | 46 | 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
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
Recombinant annexin A5 (Annexin Pharmaceuticals) addresses Nonproliferative diabetic retinopathy, Retinal Vein Occlusion. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Recombinant protein—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: ANXA5.” 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: ANXA5 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 “Monomeric annexin a5 for use in the treatment of macular oedema or retinal vein occlusion”. The milestone feed surfaced a patent-application signal described as “Therapeutic compositions”. The milestone feed surfaced a patent-application signal described as “Process of manufacture of annexin V”.
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
- Clinical differentiation versus current standards and pipeline competitors
- Safety, dose optimization, and long-term tolerability
- Patent scope, territorial rights, manufacturing, and commercial positioning
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
HOLD / OPTION
Preserve optionality until clinical differentiation, transaction economics, and freedom-to-operate are sufficiently de-risked.
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.
