Folate receptor alpha vaccine(Mayo Clinic) Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Folate receptor alpha vaccine(Mayo Clinic) 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 Folate receptor alpha vaccine(Mayo Clinic) can convert its Therapeutic 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 | Folate receptor alpha vaccine(Mayo Clinic) (query alias: Folate receptor alpha vaccine(Mayo Clinic)) |
|---|---|
| Modality / target | Therapeutic vaccine; Not disclosed; Not disclosed |
| Highest global status | Phase 2 |
| Originator | Mayo Clinic |
| Active developers | Mayo Clinic |
The MCP disease footprint includes Endometrioid carcinoma ovary, Fallopian Tube Clear Cell Adenocarcinoma, Fallopian Tube High Grade Serous Adenocarcinoma. 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 |
|---|---|---|---|---|
| NCT06639074 | Phase 2 | Recruiting | 78 | Primary endpoint not disclosed in English source |
| NCT02978222 | Phase 2 | Terminated | 120 | Primary endpoint not disclosed in English source |
| NCT02764333 | Phase 2 | Completed | 29 | 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
Vaccination with folate receptor-alpha peptides in patients with ovarian cancer following response to platinum-based therapy: A randomized, multicenter clinical trial
Phase 2; n=120; evaluation: Negative. Reported fields: mPFS = 10.9 Month ; mPFS = 11.1 Month
A Randomized Multicenter Phase II Trial to Evaluate the Safety, Efficacy and Immunogenicity of Vaccination With Folate Receptor Alpha Peptides With GM-CSF Versus GM-CSF Alone in Patients With Platinum Sensitive Ovarian Cancer and a Response or Stable Disease to Platinum Therapy
Phase 2; n=120; evaluation: Not stated in English source. Reported fields: PFS(Median) = 11.1 Month (95%CI, 8.1 - NA); PFS(Median) = 10.9 Month (95%CI, 8.0 - 16.8)
A Phase II Trial of TPIV200/huFR-1 (A Multi-Epitope Anti-Folate Receptor Vaccine) Plus Anti-PD-L1 MEDI4736 (Durvalumab) in Patients With Platinum Resistant Ovarian Cancer
Phase 2; n=29; evaluation: Not stated in English source. Reported fields: PR = 1 Pts
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
Folate receptor alpha vaccine(Mayo Clinic) addresses Endometrioid carcinoma ovary, Fallopian Tube Clear Cell Adenocarcinoma, Fallopian Tube High Grade Serous Adenocarcinoma. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Therapeutic 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
The milestone feed surfaced a patent-application signal described as “Application of antisense oligonucleotide in preparation of medicine for treating breast cancer”. The milestone feed surfaced a patent-application signal described as “Chimeric nucleic acid molecule with non-AUG translation initiation sequences”.
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.
