This Orilanolimab(Syntimmune, Inc.) 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.

Preserve optionality until clinical differentiation, transaction economics, and freedom-to-operate are sufficiently de-risked.
The central underwriting question is whether Orilanolimab(Syntimmune, Inc.) can convert its Monoclonal antibody profile and FcRn biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
| Asset | Orilanolimab(Syntimmune, Inc.) (query alias: orilanolimab) |
|---|---|
| Modality / target | Monoclonal antibody; FcRn; FcRn antagonists |
| Highest global status | Discontinued |
| Originator | Syntimmune, Inc. |
| Active developers | Not disclosed |
The MCP disease footprint includes no disclosed indication. 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.
| Registry | Phase | Status | Enrollment | Lead primary endpoint |
|---|---|---|---|---|
| NCT04982289 | Phase 2 | Withdrawn | Not disclosed | Adverse Events (AEs) And Serious Adverse Events (SAEs) Up To Week 24 |
| NCT04956276 | Phase 2 | Withdrawn | Not disclosed | Proportion Of Participants Achieving A ≥ 2 Grams/Deciliter (g/dL) Increase In Hemoglobin (Hgb) From Baseline To The End Of Primary Treatment |
| NCT04730804 | Phase 1 | Terminated | 34 | Number of Participants With Treatment-Emergent Adverse Events (TEAEs) |
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.

Reproduce the asset-to-trial workflow with PatSnap MCP
Phase 1; n=34; evaluation: not stated. Reported fields: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) = 7 Participants ; Number of Participants With Treatment-Emergent Adverse Events (TEAEs) = 5 Participants ; -
Phase 1; n=12; evaluation: not stated. Reported fields: AE = 3 Participants ; -; AE = 5 Participants
Phase 1/2; n=8; evaluation: not stated. Reported fields: TEAE = 8 Participants ; -; -
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.
Orilanolimab(Syntimmune, Inc.) addresses its disclosed development indications. Commercial attractiveness rests on addressable biomarker-positive patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Monoclonal antibody—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: 1 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.
| Date | Transaction | Phase at deal | Disclosed economics |
|---|---|---|---|
| 2018-09-26 | Alexion to Acquire Syntimmune | Phase 1/2 | US$400.0M upfront; US$800.0M milestones; US$1,200.0M stated total |
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.
The milestone feed surfaced a patent-application signal described as “Use of Anti-FCRN antibodies in the treatment of pemphighus and pemphigoid diseases”. The milestone feed surfaced a patent-application signal described as “Humanized affinity matured Anti-fcrn antibodies”.
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.
Cross-functional diligence should also test CMC comparability, supply chain, pharmacovigilance, regulatory correspondence, data integrity, investigator concentration, partner obligations and change-of-control restrictions.
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.
