What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • XRD-0394Drug

    Administered orally; small molecule dual inhibitor of ataxia telangiectasia mutated kinase (ATM) and DNA-PK.

  • Radiation TherapyRadiation

    For Cohort A and Cohort B, the neoadjuvant "boost" radiation dose is 1400cGy delivered over 7 fractions, and the adjuvant radiation dose is 5000cGy delivered over 25 fractions for a total dose of 6400cGy over 32 fractions, accounting for the treatment break between boost and adjuvant RT.

    For Cohort C, the radiation dose is 3500cGy delivered over 10 fractions.

  • Surgical ResectionProcedure or surgery

    Resection of tumor tissue.

Study groupRoleWhat they receive
Pre-Surgery Dose-EscalationExperimentalPatients with newly-diagnosed high grade gliomas (HGG) receiving neoadjuvant radiation therapy (RT) prior to surgical resection will be enrolled in the Pre-Surgical Dose-Escalation arm, at one of two dose levels: Participants enrolled at Pre-Surgical Dose Level 1 (DL1) will receive 160mg daily XRD-0394 on the days of radiation therapy before surgery. Participants enrolled at Pre-Surgery Dose Level 2 (DL2) will receive 300mg daily XRD-0394 on the days of radiation therapy before surgery. All patients enrolled in the pre-surgical dose escalation portion of the study will receive DL1 in the post-surgical dose-escalation portion of the study, but will not be enrolled in the Post-Surgery Dose Escalation arms for purpose of analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants who Experience Dose-Limiting Toxicities (DLTs)

    Assessed among patients who receive at least one dose of the study drug and are evaluated for dose-limiting toxicities (DLTs).

    Measured: End of DLT Monitoring Period (Pre-surgical dose-escalation: Day 8; Cohort C: Day 44; Cohorts A & B: Day 108)

Secondary outcomes (5)
  1. Progression-Free Survival (PFS)

    Assessed among Cohorts A, B, and C only. Defined as the time from the start of treatment until the first documented disease progression or death.

    Measured: Up to Year 3 Post-Enrollment

  2. Overall Survival (OS)

    Assessed among Cohorts A, B, and C only. Defined as the time from treatment initiation until death from any cause.

    Measured: Up to Year 3 Post-Enrollment

  3. Maximum Concentration (Cmax) of XRD-0394 in Resected Tumor Tissue

    Assessed among Pre-Surgical Dose-Escalation participants only.

    Measured: Day 8 (Day of Surgery)

  4. Area Under the Curve (AUC) of XRD-0394 in Resected Tumor Tissue

    Assessed among Pre-Surgical Dose-Escalation participants only.

    Measured: Day 8 (Day of Surgery)

  5. Time to Maximum Concentration (Tmax) of XRD-0394 in Resected Tumor Tissue

    Assessed among Pre-Surgical Dose-Escalation participants only.

    Measured: Day 8 (Day of Surgery)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing XRD-0394, Radiation Therapy and Surgical Resection in people with High-Grade Glioma, run by NYU Langone Health at 1 site in United States.

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 10 inclusion and 10 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: looking for participants now, as of the sponsor's last update on 2 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Contact Jonathan Yang, MD, PhD (212-731-6276, Jonathan.Yang@nyulangone.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants who Experience Dose-Limiting Toxicities (DLTs) (time frame: End of DLT Monitoring Period (Pre-surgical dose-escalation: Day 8; Cohort C: Day 44; Cohorts A & B: Day 108)). 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 2 Jan 2026.
