NCT03416530

Brief Summary

This was a Phase 1, open label, multicenter, 8-arm, dose escalation study of dordaviprone (ONC201) in pediatric patients with newly diagnosed diffuse intrinsic pontine glioma (DIPG) and recurrent/refractory H3 K27M-mutant gliomas. The primary endpoint of this study was to determine the recommended Phase 2 dose (RP2D) of dordaviprone (ONC201) in pediatric glioma patients as a single agent in combination with radiation.

Outcome Measures

Primary Outcomes (1)

  • RP2D

    Determination of recommended Phase 2 dose (RP2D) as a single agent or in combination with radiation

    28 days

Study Arms (7)

A (recurrent/refractory H3 K27M-mutant glioma)

EXPERIMENTAL

Pediatric patients with relapsed/refractory glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory) and have completed at least one line of prior therapy. Evidence of progression is not required so that ONC201 may be administered to patients in the maintenance setting or to patients with recurrent/refractory disease.

Drug: Dordaviprone (ONC201)

B (newly diagnosed DIPG)

EXPERIMENTAL

Pediatric patients with newly diagnosed diffuse intrinsic pontine glioma (DIPG), defined as tumors with a pontine epicenter and diffuse involvement of the pons, are eligible with or without histologic confirmation. If H3 K27M status of tumor is unknown or archival tumor tissue is not available, then patients must agree to submit a post-mortem biopsy specimen.

Drug: Dordaviprone (ONC201)

C (midline glioma)

EXPERIMENTAL

Pediatric patients with midline gliomas are eligible with or without histologic confirmation and must be eligible for tumor biopsy as deemed by the site Investigator.

Drug: Dordaviprone (ONC201)

D (recurrent H3 K27M-mutant glioma; CSF obtained)

EXPERIMENTAL

Pediatric patients with recurrent glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory), have completed at least one line of prior therapy, must be willing to undergo serial lumbar puncture to obtain cerebrospinal fluid (CSF), and must be scheduled to undergo sedated MRIs.

Drug: Dordaviprone (ONC201)

E (H3 K27M-mutant glioma or DIPG; liquid formulation)

EXPERIMENTAL

Patients with glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory) or have diagnosed diffuse intrinsic pontine glioma (DIPG), defined as tumors with a pontine epicenter and diffuse involvement of the pons, are eligible with or without histologic confirmation. Patients must be 2-12 weeks from completion of first-line radiation. Patients administered liquid formulation of dordaviprone (ONC201) in Ora-Sweet.

Drug: Dordaviprone (ONC201)

F (recurrent/refractory, progressive high-grade H3 K27M-mutant glioma)

EXPERIMENTAL

Pediatric patients with relapsed/refractory, histologically confirmed high-grade glioma with a known H3 K27M mutation, evidence of progressive disease contrast-enhanced brain MRI as defined by RANO-HGG criteria. Prior therapy with at least radiotherapy is required.

Drug: Dordaviprone (ONC201)

G (recurrent/refractory H3 K27M-mutant glioma; dosing twice weekly)

EXPERIMENTAL

Pediatric patients with glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory) and have completed at least one line of prior therapy will be enrolled to define the RP2D for single agent dordaviprone (ONC201) given on two consecutive days of each week.

Drug: Dordaviprone (ONC201)

Interventions

Dordaviprone is a brain-penetrant, small-molecule imipridone that acts as a mitochondrial caseinolytic protease P (ClpP) agonist and a dopamine receptor D2 (DRD2) antagonist.

Eligibility Criteria

Age2 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • to less than 19 years of age.
  • Patient body weight must be above the minimum necessary for the patient to receive the ONC201 dose indicated for the currently enrolling dose level. The minimum body weight ranges from 10-27.5kg depending on the dose level.
  • Arm A and G: Patients with glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory) and have completed at least one line of prior therapy. Evidence of progression is not required so that ONC201 may be administered to patients in the maintenance setting or to patients with recurrent disease. No more than two episodes of recurrence from radiotherapy and/or chemotherapy are allowed. Use of bevacizumab solely for treatment of radiation necrosis, pseudoprogression, or treatment effect will not be considered a recurrence. Post-mortem biopsy is required if H3 K27M status of tumor is unknown and archival tumor tissue not available.
  • Arm B: Patients with newly diagnosed diffuse intrinsic pontine glioma (DIPG), defined as tumors with a pontine epicenter and diffuse involvement of the pons, are eligible with or without histologic confirmation. Post-mortem biopsy is required if H3 K27M status of tumor is unknown and archival tumor tissue not available.
  • Arm C: Patients with midline gliomas are eligible with or without histologic confirmation and must be eligible for tumor biopsy as deemed by the site Investigator.
  • Arm D: Patients with recurrent glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory), have completed at least one line of prior therapy, must be willing to undergo serial lumbar puncture to obtain cerebrospinal fluid (CSF), and must be scheduled to undergo sedated MRIs. Local anesthesia for spinal tap is also allowed. Evidence of progression is not required so that ONC201 may be administered to patients in the maintenance setting or to patients with recurrent disease. No more than two prior episodes of recurrence from radiotherapy and/or chemotherapy are allowed. Use of bevacizumab solely for treatment of radiation necrosis, pseudoprogression, or treatment effect will not be considered a recurrence. Spinal tap should not be performed if treating clinician or lumbar puncture proceduralist has concern of signs of elevated intracranial pressure, including recent worsening in headache or somnolence.
  • Arm E: Patients with glioma who are positive for the H3 K27M mutation (positive testing in CLIA laboratory) or have diagnosed diffuse intrinsic pontine glioma (DIPG), defined as tumors with a pontine epicenter and diffuse involvement of the pons, are eligible with or without histologic confirmation. Patients must be 2-12 weeks from completion of first-line radiation.
