Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, Phase 2 study to assess the activity of tesevatinib in subjects (n = 40) with recurrent glioblastoma. This study will be conducted at up to 10 sites in the United States.

The availability of paraffin-embedded tumor sample diagnostic of glioblastoma is mandatory for entry into the study. Tumor samples will be evaluated for the EGFRvIII mutation and for EGFR gene amplification. Tissue from recurrent surgery is preferred, but tissue from initial surgery is sufficient for study entry. Baseline MRI is mandatory.

After completion of the screening assessments and confirmation of study eligibility by the Medical Monitor upon review of an inclusion package, tesevatinib will be orally administered to all patients at a dose of 300 mg once daily. A cycle will be considered as 28 days. Patients will be evaluated for efficacy according to the Response Assessment in Neuro-Oncology (RANO) criteria.

Patients who develop ≥ Grade 3 adverse event(s) considered by the investigator to be related to study drug will have study treatment interrupted until the drug-related toxicities have resolved to ≤ Grade 1. Once toxicities have resolved to ≤ Grade 1, the patient may resume study treatment at a reduced dose of 250 mg/day. No more than 1 dose reduction is permitted. Patients who require more than one dose reduction will have study drug discontinued and enter the Follow-up Period.

Patients for whom toxicity persists beyond 21 days despite dose interruption may resume study treatment only with permission from the responsible Medical Monitor.

If study treatment is withheld, the patient should be instructed not to make up the withheld doses.

Study treatment will continue until disease progression, unacceptable toxicity, patient or physician decision to discontinue, or death. Assessments for disease response will occur at Week 4 and Week 8 and then every 8 weeks thereafter using the RANO criteria.

Upon treatment discontinuation, patients will be followed every 8 weeks for survival.

Tumor samples will be used for exploratory biomarker research including, but not limited to, evaluation of EGFRvIII expression by immunohistochemistry or real-time Polymerase Chain Reaction. An appropriate definition and cutoff for EGFRvIII\^pos tumors will be established, and outcome in this subpopulation will be evaluated in addition to the overall study population.

To characterize the safety and tolerability profile of tesevatinib, patients will be monitored throughout the study for adverse events (all grades), serious adverse events, and any adverse events requiring drug interruption or discontinuation. Patients will undergo safety evaluations, including physical examinations, Karnofsky Performance Status (KPS), vital sign measurements, hematology, serum chemistry, urinalysis and electrocardiogram.

Magnetic resonance imaging (MRI) will be used to evaluate the tumor at baseline. All MRIs taken on study patients will be submitted to the sponsor for possible retrospective analysis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Glioblastoma

The single arm design assessing progression-free survival at 6 months (PFS-6) in the overall population with the ability to detect a rate of 25% is appropriate as a preliminary test of activity in patients with glioblastoma. The sample size of this study is also designed to permit the comparison of results with EGFR amplified and non-amplified tumors, as well as EGFRvIII mutated versus wild-type. The sample size is adequate to characterize the safety profile in patients with glioblastoma.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Willingness and ability to provide written informed consent and to comply with the study protocol as judged by the investigator
2. Age ≥ 18 years old
3. Kamofsky performance status ≥70%
4. Stable or decreasing dose of corticosteroids within 5 days prior to study 5. enrollment.
5. For women who are not postmenopausal (i.e., \< 12 months after last menstruation) or surgically sterile (absence of ovaries and/or uterus) and who are sexually active: agreement to use an adequate method of contraception (oral contraceptives, intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly) during the treatment period and for at least 6 months after the last dose of study drug.
6. For male patients who are sexually active and who are partners of premenopausal women: agreement to use a barrier method of contraception during the treatment period and for at least 6 months after the last dose of study drug.
7. Histologically confirmed glioblastoma. A local pathology report constitutes adequate documentation of histology for study inclusion. Patients with an initial diagnosis of a lower-grade glioma are eligible if a subsequent biopsy was determined to be glioblastoma.
8. First recurrence after concurrent or adjuvant chemoradiotherapy. Imaging confirmation of first tumor progression or regrowth as defined by the RANO criteria . A minimum of 12 weeks must have elapsed from the completion of radiotherapy to study entry to minimize the potential for MRI changes related to radiation necrosis that might be misdiagnosed as progression of disease, unless there is a new lesion outside the radiation field or unequivocal evidence of viable tumor on histopathological sampling.
9. Prior treatment with TMZ for low grade glioma or glioblastoma.
10. No more than one prior line of systemic treatment for glioblastoma. Concurrent and adjuvant TMZ-based chemotherapy, including the combination of TMZ with an investigational agent, is considered one line of therapy.
11. Prior therapy with gamma knife or other focal high-dose radiotherapy is allowed, but the patient must have subsequent histologic documentation of recurrence, unless the recurrence is a new lesion outside the irradiated field.
12. Recovery from the toxic effects of prior therapy, with a minimum time of:

1. ≥ 28 days elapsed from the administration of any prior cytotoxic agents, except ≥ 14 days from vincristine, ≥ 21 days from procarbazine, and ≥ 42 days from nitrosureas
2. ≥ 28 days elapsed from the administration of any investigational agent
3. ≥ 14 days elapsed from administration of any non-cytotoxic agent (e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid)
13. Patients who have undergone recent surgery for recurrent or progressive tumor are eligible provided that:

1. Surgery must have confirmed the recurrence
2. There must be residual disease
3. A minimum of 28 days must have elapsed from the day of surgery to first dose of the study drug. For core or needle biopsy, a minimum of 7 days must have elapsed prior to study entry
14. Availability of formalin-fixed paraffin-embedded tumor tissue diagnostic of glioblastoma.

Exclusion Criteria

1. Concurrent therapeutic intervention (including radiation therapy and NovoTTF).
2. Prior exposure to EGFR inhibitors.
3. Prior exposure to bevacizumab or other VEGF- or VEGF-receptor-targeted agent within 8 weeks of study start.
4. Prior treatment with prolifeprospan 20 with carmustine wafer.
5. Prior intracerebral agent.
6. Evidence of recent hemorrhage on baseline MRI of the brain. However, patients with clinically asymptomatic presence of hemosiderin, resolving hemorrhagic changes related to surgery, or presence of punctuate hemorrhage in the tumor are eligible.
7. Need for urgent palliative intervention for primary disease (e.g., rapidly increasing intracranial pressure, impending herniation, uncontrolled seizures).
8. Hematology:

ANC \< 1.5 x109/L; Plt \< 100 x109/L Hgb \< 9.0 g/dL within 7 days prior to enrollment. The use of transfusion or other intervention to achieve Hb ≥ 9 g/dL is acceptable.

15. Used any prescription medication during the prior 2 weeks that the investigator judges is likely to interfere with the study or to pose an additional risk to the patient in participating, specifically inhibitors or inducers of cytochrome P450 (CYP)3A4 (refer to Appendix 5). A stable regimen (≥ 4 weeks) of antidepressants of the selective serotonin re-uptake inhibitor (SSRI) class is allowed (common SSRIs include escitalopram oxalate, citalopram, fluvoxamine, paroxetine, sertraline, and fluoxetine).
