This Zotiraciclib 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: 5 August 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.
Preserve optionality until clinical differentiation, transaction economics, and freedom-to-operate are sufficiently de-risked.
The central underwriting question is whether Zotiraciclib can convert its Not disclosed profile and Not disclosed biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
| Asset | Zotiraciclib (query alias: Zotiraciclib) |
|---|---|
| Modality / target | Not disclosed; Not disclosed; Not disclosed |
| Highest global status | Not disclosed |
| Originator | Not disclosed |
| 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 |
|---|---|---|---|---|
| NCT05588141 | Phase 1/2 | Recruiting | 96 | To determine 12 months PFS in participants w/ recurrent glioma, IDH1/2-mutant, WHO grade 3 treated w/ zotiraciclib in comparison w/ the established brain tumor database matched for tumor molecular characteristics and clinical prognostic factors |
| NCT03224104 | Phase 1 | Completed | 71 | Maximum Tolerated Dose (MTD) |
| NCT03904628 | Phase 1 | Unknown status | 15 | Dose limiting toxicity (DLT) |
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 1; n=71; evaluation: not stated. Reported fields: -; -; -
临床1期; n=12; evaluation: 积极. Reported fields: mPFS = 1.77 months
Phase 1; n=not disclosed; evaluation: Negative. Reported fields: Adverse Event: Main toxicities = neutropenia, gastrointestinal disorders, and hepatotoxicity
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.
Zotiraciclib 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—Not disclosed—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 |
|---|---|---|---|
| 2021-10-06 | Cothera Bioscience Acquires Zotiraciclib from Adastra Pharmaceuticals | Phase 1 | Financial terms not disclosed |
| 2021-09-06 | 甫康药业与Karus Therapeutics公司就研发品种CVL237(KA2237)达成全球收购协议 | Phase 1 | Financial terms not disclosed |
| 2015-11-17 | Tragara and Lee's Pharma Enter into Exclusive Licensing Agreement to Develop and Commercialize TG02 in Greater China Market and South East Asia | Phase 1 | 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.
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.
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.
