Brief summary: Background:

Zotiraciclib (TG02) is an investigational drug that penetrates the blood-brain barrier and might treat brain tumors. Temozolomide (TMZ) is a drug used to treat brain tumors.

Objective:

To find out if Zotiraciclib (TG02) is safe, and to find out if it in combination with TMZ is as effective as TMZ alone in people with brain tumors.

Eligibility:

People ages 18 and older with a brain tumor that has progressed after standard treatment

Design:

In phase I part, the Bayesian optimal interval (BOIN) design will be used to find the maximum tolerated dose (MTD) of Zotiraciclib (TG02) for Arm 1 (dose dense TMZ) and Arm 2 (metronomic TMZ) independently. Then a randomized cohort expansion compared progression free survival at 4 months (PFS4) of the two arms for an efficient determination of a TMZ schedule to combine with Zotiraciclib at MTD.

In Phase II part, a Bayesian design based on posterior probability will be used to monitor efficacy.

Participants will be screened with:

* Medical history
* Physical exam
* Blood and urine tests
* Magnetic resonance imaging (MRI) of the brain if they have not had one in 14 days
* Heart test
* Tissue sample from prior surgeries

Participants will take Zotiraciclib (TG02) plus TMZ by mouth in 28-day cycles.

* Some will take TMZ for 7 days on and 7 days off. Others will take it every day.
* They will all take Zotiraciclib (TG02) three days before Cycle 1, and then on four days during every cycle.
* They will all get treatment to prevent vomiting and diarrhea before and for 24 hours after each Zotiraciclib (TG02) dose.
* They will all keep a diary of when they take the drugs and their symptoms.

Participants will have study visits. These include:

* Physical exam, heart test, quality of life questionnaire, brain MRI, and urine tests every 4 weeks
* Blood tests every 2 weeks

Participants will continue treatment until their disease gets worse or they have intolerable side effects.

Participants will also be enrolled in another protocol to test molecular markers for their brain tumor.

Detailed description: Background:

* Zotiraciclib (TG02) is a pyrimidine-based multi-kinase inhibitor that has been shown to have inhibitory effects on cyclin-dependent kinases (CDKs), Janus Kinase 2 (JAK2) and Fm-like tyrosine kinase 3 (Flt3). It is orally administered and penetrates blood brain barrier (BBB). There is clinical experience in using Zotiraciclib (TG02) as both a single agent and in combination with other chemotherapy agents for cancer treatment.
* Temozolomide (TMZ) is an oral alkylating agent that has proven efficacy in anaplastic glioma and glioblastoma. It was approved by the United States (U.S.) Food and Drug Administration (FDA) to treat anaplastic astrocytoma and glioblastoma in adults. Both a dose-dense (dd) schedule, 7 days on and 7 days off and a metronomic (mn) daily dosing schedule have been used to treat recurrent high-grade gliomas.
* Our preclinical data have demonstrated that Zotiraciclib (TG02) down-regulates cyclin-dependent kinase 9 (CDK9) activity and its target proteins, such as anti-apoptotic protein myeloid-cell leukemia (Mcl-1), X-linked inhibitor of apoptosis (XIAP) and survivin. A treatment with Zotiraciclib (TG02) and TMZ has synergistic anti-glioma effects in a variety of glioma models with different genetic background. This serves as the basis for this proposed clinical trial.

Objectives:

Phase I:

-To determine the maximum tolerated dose (MTD) of Zotiraciclib (TG02) plus TMZ using both the dd and mn TMZ schedules in adult patients with recurrent anaplastic astrocytoma or glioblastoma/gliosarcoma.

To select the treatment regimen with better progression free survival (PFS)4 between Zotiraciclib (TG02) plus dd TMZ or mn TMZ at each of the MTDs following cohort expansion.

Phase II:

-To determine the efficacy of Zotiraciclib (TG02) plus TMZ versus TMZ alone in patients with recurrent World Health Organization (WHO) grade III or IV astrocytoma as determined by progression free survival.

Eligibility:

* Documented pathology diagnosis of anaplastic astrocytoma \[WHO grade III\], or glioblastoma/gliosarcoma (WHO grade IV) with recurrent disease. If the pathology diagnosis is anaplastic glioma or anaplastic oligoastrocytoma, evidence of either intact 1p/19q chromosomes or molecular features suggesting astrocytic tumor must be present. (including, but not limited to α-thalassemia mental retardation X-linked (ATRX) and/or tumor protein P53 (TP53) mutation)
* No prior use of bevacizumab as a treatment for brain tumor.
* No more than two prior relapses for Phase I and no more than one prior relapse for Phase II.
* Patients must have recurrent disease, either histologically proven or with imaging suggestive of recurrent disease
* Tumor tissues available for review to confirm the histologic diagnosis.
* Tumor tissue blocks available for molecular profiling analysis.

Design:

* Phase I:

  * This portion of the study is conducted in two stages: The MTD finding and cohort extension. Two treatment arms and several dose levels are planned.
  * In the MTD finding part, TMZ with two alternate schedules (dd and mn) in combination with Zotiraciclib (TG02) will be administered.
  * A cohort extension of both arms will be performed at each MTD and the treatment arm with a better progression free survival at 4 months (PFS4) will be selected for the combination treatment arm for Phase II.
  * Pharmacokinetic, pharmacogenetic studies and neutrophil analysis will be performed during the cohort extension of both arms.
  * A maximum of 72 patients will be enrolled to this component for the trial.
* Phase II:

  --Patients will be randomized between two competing treatment arms: ("winner" of dd vs mn) TMZ + Zotiraciclib (TG02) versus dd/mn TMZ alone using a Bayesian clinical trial design. The dosage for the combination arm will be derived from the MTD determined in the Phase I component of the study.
* The treatment schedule will be identical to that described above in the phase I component, with each cycle comprising 28 days.
* Patients will continue treatment until tumor progression or unacceptable toxicity occurs.
* At progression, patients randomized to the control arm (Temozolomide \[TMZ\] alone) will be offered the opportunity to continue TMZ and additional treatment with Zotiraciclib (TG02).

  * At least 2 weeks (14 days) have elapsed from the date of surgery and the patients have recovered from the effects of surgery.
  * Evaluable or measureable disease following resection of recurrent malignant glioma is not mandated for eligibility into the study.
  * To best assess the extent of residual disease post-operatively, an magnetic resonance imaging (MRI) should be done no later than 96 hours in the immediate post-operative period or at least within 4 weeks post- operatively, within 14 days prior to registration. If the 96-hour scan is more than 14 days before registration, the scan needs to be repeated. The patient must have been on a stable steroid dose for at least 5 days prior to the baseline MRI. Steroids may be initiated as clinically indicated once baseline imaging has been completed with a goal of titrating steroids as soon as clinically warranted.
* Patients must have received prior radiation therapy and must have an interval of greater than or equal to 12 weeks (84 days) from the completion of radiation therapy to study entry except if there is unequivocal evidence for tumor recurrence (such as histological confirmation or advanced imaging data such as positron emission tomography (PET) scan) in which case the principal investigators discretion may determine appropriate timepoint at which study therapy may begin.
* Women of childbearing potential must have a negative beta-human chorionic gonadotropin (HCG) pregnancy test documented within 14 days prior to registration. The effects of Zotiraciclib (TG02) on the developing human fetus are unknown. For this reason, women of childbearing potential must not be pregnant, must not be breast-feeding, and must practice adequate contraception for the duration of the study, and for 30 days after the last dose of study medication.
* Male patients on treatment with Zotiraciclib (TG02) must agree to use an adequate method of contraception for the duration of the study, and for 30 days after the last dose of study medication as the effects of Zotiraciclib (TG02) on the developing human fetus are unknown.

EXCLUSION CRITERIA:

* Patients who are receiving any other investigational agents. However, prior enrollment on a study using investigational agents is acceptable
* Patients with prior bevacizumab use for tumor treatment. Patients who received bevacizumab for symptom management, including but not limited to cerebral edema, pseudoprogression can be included in the study (To date, there have been no effective regimens developed for recurrent malignant gliomas that are refractory to bevacizumab. Inclusion of this patient population may impact the ability to determine the efficacy of Zotiraciclib (TG02) with Temozolomide (TMZ.)
* Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from providing informed consent.
* Any condition, including the presence of clinically significant laboratory abnormalities, which places the patient at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study. These would include:

  * Active infection (including persistent fever) including known history of human immunodeficiency virus (HIV) or Hepatitis C infection, because these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy.
  * Diseases or conditions that obscure toxicity or dangerously alter drug metabolism
  * Serious concurrent medical illness e.g. symptomatic congestive heart failure
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to temozolomide and/or Zotiraciclib (TG02).
