NCT07623616 Ziftomenib Refractory acute myeloid leukemia Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook
Turn a newly registered trial into a decision-ready clinical landscape. This report examines NCT07623616 using PatSnap Clinical Trials MCP for protocol design and endpoint evidence, with Drug & Asset MCP and Company & Deal Intelligence MCP used as the companion asset and sponsor enrichment workflow.

MCP evidence snapshot: 23 July 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07623616 is a hot trial to watch
Refractory acute myeloid leukemia is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07623616 is notable because it evaluates Ziftomenib in a Phase 2 design sponsored by Kyowa Kirin Co., Ltd.. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

| Phase / status | Phase 2 / Recruiting |
| Intervention | Ziftomenib |
| Sponsor | Kyowa Kirin Co., Ltd. |
| Geography | Japan |
| Enrollment | [object Object] |

| Primary completion / readout proxy | [object Object] |
Protocol design and endpoint interpretation
This is the first study to administer ziftomenib to Japanese patients. In this study, the efficacy, safety, and pharmacokinetics of ziftomenib will be evaluated in patients with relapsed or refractory NPM1-mutated acute myeloid leukemia
Allocation is N/A, masking is None (Open Label), and the intervention model is Single Group Assignment. Planned enrollment of [object Object] participants across Japan shapes statistical precision, execution risk and external validity. Interpretation should account for baseline risk, prior therapy, assessment schedule, missing-data handling and clinical relevance—not only statistical significance.
- CR+CRh rate (Best overall response assessed every 28 days from first dose until disease progression or withdrawall, an average of 16weeks)
Readout outlook and evidence gap
The current protocol points to [object Object] as the best available readout proxy. Because this is an active or newly posted study, a trial-specific result citation is not included until a normalized clinical-trial-result record becomes available. That gap is itself operationally important: teams should monitor first result indexing, conference abstracts, protocol amendments and changes to the primary-completion date.

Asset and sponsor context
Drug & Asset MCP profile: Ziftomenib is indexed as Small molecule drug, with target MLL1 x menin, mechanism MLL1 inhibitors, menin inhibitors, and global highest development status Approved.
Company & Deal Intelligence MCP profile: Kyowa Kirin Co., Ltd. did not return an exact normalized organization match in this snapshot. The organization workflow adds identity, location, portfolio and partnering context where available.
The sponsor profile matters because scientific rationale alone does not determine development value. Manufacturing readiness, portfolio fit, geographic reach, partnering capacity and the ability to fund confirmatory development can determine whether a positive signal becomes a competitive asset.
White space around this program
- Sharper patient selection: prospective biomarker or phenotype definitions that identify who is most likely to benefit.
- Clinically interpretable endpoints: outcomes connecting activity with function, symptoms, survival or treatment burden.
- Comparator relevance: evidence against the most decision-relevant contemporary standard of care.
- Broader external validity: evidence across additional geographies, demographic groups and real-world settings.
- Operational differentiation: a development path that closes the readout gap without sacrificing safety or durability.
What to monitor next
Monitor recruitment, enrollment changes, protocol amendments, endpoint hierarchy, primary-completion timing, first result indexing, asset ownership and sponsor partnerships. A change in endpoint, population or ownership can alter the probability of success before a headline data release.
Bottom line
NCT07623616 provides a focused lens on Refractory acute myeloid leukemia development. Its value will be determined by whether Ziftomenib can convert the current Phase 2 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
