| Anaplastic Astrocytoma Recurrent Anaplastic Astrocytoma | Drug: Eflornithine Drug: Lomustine | Phase 3 |
This study will consist of 4 study periods of up to 50 months in total, consisting of:
Screening Period - A maximum screening duration of 4 weeks.
Treatment Period - Treatment Arm A up to 24 months; Treatment Arm B up to 12 months.
End of Treatment Visit - A minimum of 4 weeks post last treatment for both arms.
Follow-Up Period - Up to approximately 36 months, or until patient death.
A total of approximately 340 patients will be randomized in a 1:1 ratio to receive either eflornithine + lomustine or lomustine alone.

- Overall survival [ Time Frame: 4 years ]
- Progression-free survival (PFS) [ Time Frame: 4 years ]
- Objective response rate (ORR) [ Time Frame: 4 years ]
- Clinical benefit response (CBR) based on magnetic resonance imaging (MRI) criteria [ Time Frame: 4 years ]
- OS rate at 18 months (OS-18) [ Time Frame: 18 months ]
- Relevance of OS, PFS, ORR, and CBR to commonly used molecular/genetic biomarkers obtained from most recent pre-study tumor samples [ Time Frame: 4 years ]
- Pharmacokinetic Analysis - Maximum concentrations (Cmax) of eflornithine in plasma will be determined. [ Time Frame: 1 Month ]
- PK - Area under the curve (AUC) of eflornithine in plasma will be determined. [ Time Frame: 1 Month ]

| Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Patients must meet all of the following inclusion criteria to be eligible for participation in this study:
- Surgical or biopsy-proven diagnosis of WHO grade 3 AA.
-
First AA tumor progression or recurrence ≤ 6 months prior to randomization based on MRI using T2 hyperintesity, gadolinium (Gd)-contrast enhancement, or both. To avoid enrollment of patients with glioblastoma, patients with Gd-contrast enhancing tumors will be eligible if there is no necrosis seen on MRI and any of the following criteria is true:
- Gd-contrast lesion margins are not clearly defined,
- Gd-contrast lesions are only measurable in one dimension,
- Gd-contrast lesion has two perpendicular diameters less than 10 mm,
- Gd-contrast lesion has two perpendicular diameters greater than 10 mm but less than 20 mm and lesion does not demonstrate central necrosis,
- Recent histopathological confirmation of WHO grade 3 AA
- Received EBRT and temozolomide chemotherapy prior to first tumor progression or recurrence of WHO Grade 3 AA.
- Completion of EBRT ≥ 6 months prior to randomization.
- A patient whose AA tumor has progressed or recurred and has had another surgical resection prior to randomization will be eligible if a) pathology review confirms AA, and b) post-surgical MRI demonstrates measurable tumor on T2 FLAIR.
- Karnofsky Performance Status (KPS) score of ≥ 70.
Exclusion Criteria:
Patients who meet any of the following exclusion criteria are not eligible for study participation:
- MRI defining progression is consistent with a diagnosis of glioblastoma or radiation necrosis.
- Patients who are considered to be refractory to EBRT and temozolomide but who have not progressed.
- Prior systemic therapy for recurrence of AA.
- Presence of extracranial or leptomeningeal disease.
- Prior lomustine use.
- Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the patient unsuitable for the study.
- Pregnant or breastfeeding.
