Avitinib Maleate Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Avitinib Maleate Drug Asset Due Diligence Report was built with PatSnap Life Sciences MCP workflows.

Decision date: 23 July 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: GO
Decision memo
Advance diligence: development maturity and available evidence support continued investment, subject to indication-specific safety, IP, and commercial gates.
The central underwriting question is whether Avitinib Maleate can convert its Small molecule drug profile and EGFR T790M biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | Avitinib Maleate (query alias: Avitinib Maleate) |
|---|---|
| Modality / target | Small molecule drug; EGFR T790M; EGFR T790M inhibitors |
| Highest global status | Phase 3 |
| Originator | Zhejiang ACEA Pharmaceutical Co., Ltd. |
| Active developers | Hangzhou ACEA Pharmaceutical Research Co. Ltd., Acea Bio (Hangzhou) Co., Ltd., ACEA Therapeutics, Inc. |
The MCP disease footprint includes Non-Small Cell Lung Cancer, Recurrent Non-Small Cell Lung Cancer, B-Cell Lymphoma. 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 |
|---|---|---|---|---|
| NCT03856697 | Phase 3 | Unknown status | 406 | Assess the efficacy of Abivertinib: Progression Free Survival (PFS) |
| NCT04528667 | Phase 2 | Completed | 396 | Proportion of subjects discharged from hospital |
| NCT05361915 | Phase 2 | Suspended | 100 | 6-month radiographic progression-free survival |
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, Open Label, Randomized Study of the Efficacy and Safety of STI-5656 (Abivertinib Maleate) With Standard of Care Versus Standard of Care in Subjects Hospitalized With COVID-19
Phase 2; n=96; evaluation: not stated. Reported fields: Percentage of Subjects Alive and Free of Respiratory Failure at Day 28 = 40 Participants ; -; -
Sorrento Announces Significant Positive Pivotal Trial Results as Assessed by an Independent Review Committee (IRC) With Matured Long-Term (Over Three Years) Follow-Up Data of Abivertinib
Phase 2; n=209; evaluation: Positive. Reported fields: ORR = 56.5 %
A novel third generation EGFR tyrosine kinase inhibitor Abivertinib for EGFR T790M mutant Non-Small Cell Lung Cancer: a multicenter phase1/2 study
Phase 1/2; n=368; evaluation: Positive. Reported fields: ORR = 52.2 % (95%CI, 45.2 - 59.1); -; -
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
Avitinib Maleate addresses Non-Small Cell Lung Cancer, Recurrent Non-Small Cell Lung Cancer, B-Cell Lymphoma. Commercial attractiveness rests on addressable biomarker-positive patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Small molecule drug—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: 2 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.
5. Transaction precedent and economics
| Date | Transaction | Phase at deal | Disclosed economics |
|---|---|---|---|
| 2021-08-03 | Sorrento Mexico and the National Institute of Genomic Medicine (INMEGEN) of Mexico Government Execute Memorandum of Understanding (MOU) for Rapid Clinical Development of COVID-19 Diagnostics | Not disclosed | Financial terms not disclosed |
| 2020-05-21 | Sorrento Enters Into Binding Term Sheet to Acquire Exclusive Rights to Abivertinib with Completed Registrational Trial Data in Non-Small Cell Lung Cancer | NDA/BLA | US$15.0M 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.
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. Confirm that licensed patents, data and know-how track every granted territory and field.
7. Principal risks and diligence gates
- Therapeutic index across KRAS/BRAF mutation subgroups
- On-target toxicity and adaptive MAPK resistance
- Lack of matched efficacy results in the current MCP result set
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
GO
Advance diligence: development maturity and available evidence support continued investment, subject to indication-specific safety, IP, and commercial gates.
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.
