Model description
This is a Phase 1 dose-escalation study with a Part 2 expansion to evaluate the safety, PK, PD, and preliminary antitumor activity of orally administered DSP 0390 in patients with recurrent high-grade glioma. Patients in this study will receive DSP-0390 orally once daily. The study will be divided into 28-day cycles for safety and response assessments. Patients will continue treatment until progression of disease, unacceptable toxicity, withdrawal of consent, loss to follow-up, or discontinuation of the patient by the investigator. Dose-escalation will evaluate increasing dose levels of DSP-0390 to determine the MTD and/or a suitable lower dose for expansion (the RDE) in patients with recurrent WHO Grade III or IV malignant glioma. Once the MTD and/or RDE has been established, the dose escalation (Part 2) will evaluate preliminary clinical activity and the safety and tolerability of DSP-0390 in patients with recurrent WHO Grade 4 glioblastoma multiforme (GBM).

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing DSP-0390 in people with High Grade Glioma and Glioblastoma Multiforme, run by Sumitomo Pharma America, Inc. at 9 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose Escalation: Assess safety of DSP-0390 by Incidence of TEAEs and SAEs in adult patients with recurrent high-grade glioma (time frame: From date of treatment through 30 days after End of Treatment an average of 6 months). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2026.
