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 Sorafenib Tosylate can convert its Small molecule drug profile and BRAF x CRAF x FLT3 x PDGFRβ x RET x VEGFR1 x VEGFR2 x VEGFR3 x c-Kit biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
| Asset | Sorafenib Tosylate (query alias: sorafenib) |
|---|---|
| Modality / target | Small molecule drug; BRAF x CRAF x FLT3 x PDGFRβ x RET x VEGFR1 x VEGFR2 x VEGFR3 x c-Kit; BRAF inhibitors, CRAF inhibitors, FLT3 inhibitors |
| Highest global status | Approved |
| Originator | Onyx Pharmaceuticals, Inc. |
| Active developers | Bayer Yakuhin Ltd., Merck Sharp & Dohme Corp., Fudan University |
The MCP disease footprint includes Thyroid Cancer, Unresectable Hepatocellular Carcinoma, Advanced Hepatocellular Carcinoma. 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 |
|---|---|---|---|---|
| NCT06972641 | Phase 2/3 | Recruiting | 126 | EFS |
| NCT07264010 | Phase 2/3 | Not yet recruiting | 87 | Molecular response rate after three courses of treatment |
| ChiCTR2600120015 | Not Applicable | Not yet recruiting | 60 | Complete Response (CR) + Complete Response with Incomplete Hematologic Recovery (CRi) rate and Molecular Response Negative (MRD-negative) rate after first treatment cycle |
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.

Phase 2; n=72; evaluation: Positive. Reported fields: PFS(6-month) = 61.1 % ; PFS(6-month) = 63.9 %
Not Applicable; n=5028; evaluation: Non-inferior. Reported fields: OS(median) = 501.0 day ; OS(median) = 519.0 day
Not Applicable; n=60; evaluation: Positive. Reported fields: AE(grade 1-2) = 72.0 %
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.
Sorafenib Tosylate addresses Thyroid Cancer, Unresectable Hepatocellular Carcinoma, Advanced Hepatocellular Carcinoma. 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: 4 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 |
|---|---|---|---|
| 2025-03-06 | 拜耳医药授予亿帆医药拜万戈和多吉美在中国的独家市场推广权益 | Approved | Financial terms not disclosed |
| 2025-02-07 | Chong Kun Dang to exclusively distribute and sell Bayer's Nexavar and Stivarga | Approved | Financial terms not disclosed |
| 2013-08-25 | Amgen To Acquire Onyx Pharmaceuticals For $125 Per Share In Cash | Approved | Financial terms not disclosed |
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 “Preparation method of sorafenib tosylate”. The milestone feed surfaced a patent-application signal described as “Combination of YAP protacs and sorafenib for use in the treatment of cancer”.
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.
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.
