Laser Interstitial Thermal Therapy and Lomustine in Treating Patients With Recurrent Glioblastoma or Anaplastic Astrocytoma

Phase II Study of Laser Interstitial Thermal Therapy (LITT) in Recurrent Glioblastoma

This phase II trial studies how well laser interstitial thermal therapy and lomustine work in treating patients with glioblastoma or anaplastic astrocytoma that has come back. Using laser to heat the tumor cells may help to kill them. Drugs used in chemotherapy, such as lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving laser interstitial thermal therapy and lomustine may work better in treating patients with glioblastoma or anaplastic astrocytoma.

PRIMARY OBJECTIVES:

I. Determine the disease control rate at 6 months in patients with recurrent glioblastoma or isocitrate dehydrogenase (IDH)-wildtype anaplastic astrocytoma treated with Laser Interstitial Thermal Therapy (LITT) at recurrence, followed by salvage chemotherapy.

SECONDARY OBJECTIVES:

I. Estimate overall survival (OS) of patients with recurrent glioblastoma, or isocitrate dehydrogenase (IDH)-wildtype anaplastic astrocytoma treated with LITT at tumor recurrence, followed by salvage chemotherapy.

II. Estimate time to progression (TTP) of patients with recurrent glioblastoma, or isocitrate dehydrogenase (IDH)-wildtype anaplastic astrocytoma that are treated with LITT at tumor recurrence, followed by salvage chemotherapy.

III. Analyze volumetric data consisting of thermal damage threshold lines and overall tumor volume to determine any role of 'extent of ablation' in outcomes (OS and/or TTP).

IV. Characterize the safety profile of LITT followed by treatment with lomustine chemotherapy in the recurrent disease setting, using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

V. Assess the long-term steroid requirements following LITT, compared to historical controls.

VI. Determine the radiographic evolution of LITT-treated glioblastoma over time, using conventional magnetic resonance imaging (MRI) (T1 pre and post-contrast images, T2-weighted images [T2WI], fluid attenuating inversion recovery [FLAIR] images) and advanced brain tumor imaging (ABTI) [magnetic resonance (MR) perfusion [dynamic susceptibility contrast (DSC), dynamic contrast enhancement (DCE) and arterial spin labeling (ASL)], MR-diffusion, and MR spectroscopy), to include quantitative tumor metrics (volumetric extent of ablation and Response Assessment in Neuro-Oncology [RANO] criteria).

VII. Analyze health care utilization as measured by length of hospital stay following LITT (including inpatient rehabilitation care).

VIII. Evaluate patients' functional status (using the Karnofsky performance score [KPS] and the occurrence of symptoms [using the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT[English])] self-reporting tool), and correlate to disease progression and tolerance to treatment.

EXPLORATORY OBJECTIVES:

I. Identify correlative tumor and peripheral blood molecular markers that impact outcomes, etc, and identify inflammatory/immunologic markers to assess neoantigen expression, etc, if sufficient tissue is available.

II. Identify and characterize changes in tumor tissue following LITT, by analyzing and comparing pre- and post-procedure tissue samples, if sufficient tissue is available.

OUTLINE:

Patients undergo LITT at baseline and receive lomustine orally (PO) on day 1. Treatment with lomustine repeats every 42 days for up to 6 cycles in the absence of disease progression or unaccepted toxicity.

After completion of study treatment, patients are followed up every 3 months.

Inclusion Criteria:

• Patients must have histologically-proven, recurrent supratentorial grade IV glioblastoma (or grade III IDH-wildtype anaplastic astrocytoma), for which a complete surgical resection is unsafe due to location, shape, or size of the tumor. Diagnosis of recurrence will be established by biopsy and frozen section immediately prior to initiating LITT procedure. If findings on frozen section are not consistent with recurrence (glioblastoma or recurrent IDH-wildtype anaplastic astrocytoma), decision to proceed with LITT procedure will be at the discretion of the neurosurgeon (only patients with histologically-proven recurrent tumor will be evaluable for efficacy).

• All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must have signed an authorization for the release of their protected health information. Patients must be registered prior to treatment on study.

• Patients must have a Karnofsky performance score (KPS) > 60.

• Patients must have received standard of care therapy with chemoradiation with temozolomide followed by adjuvant chemotherapy with temozolomide. Patients may have received one additional chemotherapy regimen (other than lomustine) in addition to adjuvant temozolomide prior to study entry (patients at either first or second recurrence are eligible).

• In the context of this clinical trial, a lesion suitable for LITT is single, enhancing, supratentorial, at least 2 cm from inner table of skull over the hemispheric convexity, and > 1 cm, but < 4 cm in cross-sectional dimension, including thalamic tumor (=< 3 cm).

• Patients must have stable cardiovascular, neurovascular and neurological status, and be considered surgical candidates, as determined by any relevant pre-operative assessments, at the neurosurgeon's discretion.

• Patients must not be receiving concurrent anti-tumor treatment and must have recovered from toxicity of prior treatment. Minimum interval required: 1) > 6 weeks following nitrosourea chemotherapy; 2) > 4 weeks after recovering from any non-nitrosourea drug or systemic investigational agent; 3) > 2 weeks after receiving any non-cytotoxic anti-tumor drug; 4) > 4 weeks after receiving radiation therapy (> 12 weeks following upfront concurrent chemoradiation); 5) > 2 weeks following Optune device use.

• Patients must not have previously undergone an intracranial LITT procedure.

• White blood cell (WBC) > 3,000/ul (performed within 14 days (+ 3 working days) prior to registration)

• Absolute neutrophil count (ANC) > 1,500/mm^3 (performed within 14 days (+ 3 working days) prior to registration)

• Platelet count of > 100,000/mm^3 (may be reached by transfusion) (performed within 14 days (+ 3 working days) prior to registration)

• Hemoglobin > 10 gm/dl (may be reached by transfusion) (performed within 14 days (+ 3 working days) prior to registration)

• Women of childbearing potential must have a negative B-Human chorionic gonadotropin (HCG) documented within 7 days prior to registration and must agree to practice adequate contraception as defined below. Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), includes any female who has had:

  • A hysterectomy
  • A bilateral oophorectomy
  • A bilateral tubal ligation
  • Is post-menopausal: Subjects not using hormone replacement therapy (HRT) must have experienced total cessation of menses for >= 1 year and be greater than 45 years in age, OR, in questionable cases, have a follicle stimulating hormone (FSH) value > 40 mIU/mL and an estradiol value < 40 pg/mL (< 140 pmol/L).

• Subjects using HRT must have experienced total cessation of menses for >= 1 year and be greater than 45 years of age OR have had documented evidence of menopause based on FSH and estradiol concentrations prior to initiation of HRT.

• Childbearing potential includes any female who has had a negative serum pregnancy test within 7 days of study registration, and agrees to use adequate contraception. Acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows:

  • Complete abstinence from sexual intercourse for 14 days before starting treatment, through the treatment, and for at least 1 month after the last dose of temozolomide
  • Oral contraceptive, either combined or progestogen alone. A second barrier method is required during the first month of treatment with oral contraceptives
  • Injectable progesterone
  • Implants of levonorgestrel
  • Estrogenic vaginal ring
  • Percutaneous contraceptive patches
  • Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year

  • Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository). Female participants who are lactating should discontinue nursing prior to the first dose of temozolomide and should refrain from nursing throughout the treatment period and for 42 days following the last dose of lomustine.
