LN-145-S1 Drug Asset Due Diligence Report 2026

This LN-145-S1 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 memo

Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.

The central underwriting question is whether LN-145-S1 can convert its TIL therapy 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	LN-145-S1 (query alias: LN-145-S1)
Modality / target	TIL therapy; Not disclosed; T lymphocyte replacements
Highest global status	Phase 2
Originator	Iovance Biotherapeutics, Inc.
Active developers	Iovance Biotherapeutics, Inc.

The MCP disease footprint includes Melanoma, Anaplastic Thyroid Carcinoma, Chondrosarcoma. 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
NCT06566092	Phase 1	Active, not recruiting	40	Primary endpoint not disclosed in English source
NCT04111510	Phase 2	Completed	6	Primary endpoint not disclosed in English source
NCT03935347	Phase 2	Withdrawn	0	Primary endpoint not disclosed in English source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

A Phase 2 Study of Autologous Tumor Infiltrating Lymphocytes (LN-145) in Patients With Pretreated Metastatic Triple Negative Breast Cancer

Phase 2; n=6; evaluation: Not stated in English source. Reported fields: Safety Profile = 3 Pts

A Phase 2, Multicenter Study to Evaluate the Efficacy and Safety of Autologous Tumor Infiltrating Lymphocytes (LN-145/LN-145-S1) for the Treatment of Patients With Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck

Phase 2; n=64; evaluation: Not stated in English source. Reported fields: ORR = 37.5 % (95%CI, 8.5 - 75.5); ORR = 5.9 % (95%CI, 0.1 - 28.7)

MA15.08Multicenter Phase II Trial of LN-145 TIL Cell Therapy plus Pembrolizumab in Patients with ICI-Naïve Metastatic NSCLC

Phase 2; n=17; evaluation: Positive. Reported fields: CR = 2 Pts ; ORR = 80.0 % (95%CI )

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

LN-145-S1 addresses Melanoma, Anaplastic Thyroid Carcinoma, Chondrosarcoma. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—TIL therapy—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

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.
