Dapolsertib Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Dapolsertib 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: 16 September 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: CONDITIONAL GO
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 Dapolsertib can convert its Small molecule drug profile and FLT3 x PIM biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | Dapolsertib (query alias: Dapolsertib) |
|---|---|
| Modality / target | Small molecule drug; FLT3 x PIM; FLT3 inhibitors, PIM family inhibitors |
| Highest global status | Phase 2 |
| Originator | Ryvu Therapeutics SA |
| Active developers | Ryvu Therapeutics SA, Stemline Therapeutics, Inc., Menarini Von Heyden GmbH |
The MCP disease footprint includes Aggressive B-Cell Non-Hodgkin Lymphoma, Diffuse Large B-Cell Lymphoma, Acute Myeloid Leukemia. 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 |
|---|---|---|---|---|
| NCT06534437 | Phase 2 | Recruiting | 178 | Primary endpoint not disclosed in English source |
| NCT03008187 | Phase 1/2 | Completed | 73 | 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 I/II Study of SEL24 in Patients With Acute Myeloid Leukemia
Phase 1/2; n=73; evaluation: Not stated in English source. Reported fields: Part 1 and Part 2: Number of Participants Experiencing Treatment-emergent Adverse Events = 2 Pts ; Part 1 and Part 2: Number of Participants Experiencing Treatment-emergent Adverse Events = 3 Pts
Phase 1/2 study of SEL24/MEN1703, a first-in-class dual PIM/FLT3 kinase inhibitor, in patients with IDH1/2-mutated acute myeloid leukemia: The DIAMOND-01 trial.
Phase 1/2; n=20; evaluation: Positive. Reported fields: Mild Adverse Event = Grade ≥3 TEAEs (≥10%) were pneumonia (33%) and asthenia (17%), both unrelated to study drug
RESULTS FROM DIAMOND-01 (CLI24-001) TRIAL: FIRST IN HUMAN STUDY OF SEL24/MEN1703, A DUAL PIM/FLT3 KINASE INHIBITOR, IN PATIENTS WITH ACUTE MYELOID LEUKEMIA
Phase 2; n=48; evaluation: Positive. Reported fields: CR/CRi = 4 Pts
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
Dapolsertib addresses Aggressive B-Cell Non-Hodgkin Lymphoma, Diffuse Large B-Cell Lymphoma, Acute Myeloid Leukemia. Commercial attractiveness rests on addressable 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 MCP screen returned 1 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 |
|---|---|---|---|
| 2017-03-28 | Selvita and Menarini Group Announce Global License Agreement for Clinical Stage Oncology Drug PIM/FLT3 Inhibitor SEL24 | Phase 1/2 | 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.
6. IP and freedom-to-operate screen
The milestone feed surfaced a patent-application signal described as “Metformin combination therapy for use in cancer treatment”. The milestone feed surfaced a patent-application signal described as “Cancer combination therapy including a FLT3-inhibitor”. The milestone feed surfaced a patent-application signal described as “Treating myeloid disorders”.
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
- Therapeutic index and off-target toxicity
- Resistance biology and biomarker-defined patient selection
- Differentiation from established and emerging standards
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
CONDITIONAL GO
Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.
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.
