Laser Interstitial Thermal Therapy (LITT) and Lomustine (CCNU) for Recurrent Glioblastoma

Korábbi kezelés

• Patients who are not surgical candidates for stereotactic biopsy or laser ablation.
• Prior treatment with nitrosourea agents (e.g. lomustine [CCNU], carmustine [BCNU], nimustine [ACNU]).
• Prior treatment with polifeprosan 20 with carmustine wafer.
• Prior treatment with bevacizumab.
• Patients who have received any investigational agents ≤ 4 weeks or 5 drug half-lives (whichever is shorter) prior to commencing study treatment.
• History of intracerebral abscess within 6 months prior to Day 1.
• Major surgical procedure, open biopsy, or significant traumatic injury ≤ 28 days prior to Day 1, or anticipation of the need for a major surgical procedure during the course of the study.

Más betegség

• Evidence of recent hemorrhage on baseline MRI of the brain with the following exceptions: (1) presence of hemosiderin, (2) resolving hemorrhagic changes related to surgery, or (3) presence of punctate hemorrhage in the tumor.
• Serious non-healing wound, ulcer, or bone fracture.
• Known hypersensitivity to any component of lomustine (CCNU).
• Uncontrolled intercurrent illness or unstable systemic disease, including, but not limited to, ongoing or active infection, uncontrolled hypertension, or serious cardiac arrhythmia requiring medication that would interfere with participant safety or limit compliance with the study requirements.
• Known allergy to nitrosoureas (e.g., lomustine, carmustine, nimustine).
• Any condition that in the opinion of the investigator would interfere with the participant's safety or compliance while on trial

Egyéb

• Pregnancy (positive pregnancy test) or lactation.
• Unable to undergo an MRI with contrast.

• Histologically confirmed World Health Organization (WHO) 2021 defined glioblastoma. A pathology report constitutes adequate documentation of histology for study inclusion.
• Radiographic demonstration of disease progression following prior therapy.
• Patients having undergone recent resection of recurrent or progressive tumor will be eligible as long as the patient has recovered from surgery. Evaluable or measurable disease following resection of recurrent tumor is not mandated for eligibility into the study.
• Prior standard radiation for glioblastoma (short course 40 Gy, standard 60 Gy, and proton therapy are allowed).
• Patients must have recovered from the effects of prior therapy.
• The following listed agents/interventions must have been discontinued for their respective time period prior to enrollment:
  • Four weeks from cytotoxic agents (3 weeks from procarbazine, 3 weeks from vincristine, and 4 weeks from temozolomide);
  • Four weeks or 5 drug half-lives (whichever is shorter) from any investigational agent; two weeks or 5 drug half-lives (whichever is shorter) from non-cytotoxic agents (e.g. Accutane, thalidomide);
  • Twelve weeks from radiotherapy to minimize the potential for MRI changes related to radiation necrosis that might be misdiagnosed as progressive disease, or 4 weeks if a new lesion, relative to the pre-radiation MRI, develops that is outside the primary radiation field;
• Patients must have the following laboratory parameters ≤ 14 days prior to registration:
  • adequate bone marrow function defined by: i. white blood cells (WBC) ≥ 3 × 109/L , ii. absolute neutrophil count (ANC) ≥ 1.5 × 109/L , iii. platelet count of ≥ 100 × 109/L , and iv. hemoglobin ≥ 9 gm/dL b. adequate liver function defined by i. alanine transaminase (ALT, SGPT) and aspartate transaminase (AST/SGOT) < 3× institutional upper limit of normal (ULN), ii. alkaline phosphatase < 2× ULN, and iii. bilirubin < 1.5 mg/dL c. adequate renal function defined by calculated creatinine clearance ≥ 60 mL/min (see Appendix)
• Karnofsky performance status (KPS) ≥ 50 (see Appendix).
• Individuals of childbearing potential or those with partners of childbearing potential must agree to use adequate methods of contraception for the duration of study participation (including dosing interruptions) and for up to 3.5 months after the last study treatment; or be surgically sterilized.
• Patients on the following medications are allowed:
  • Anticoagulants: Patients on stable dose anticoagulants (e.g. warfarin in-range international normalized ratio [INR], low molecular-weight heparin)
  • Patients are allowed to take aspirin, clopidogrel, ticlopidine, Aggrenox, ibuprofen and other NSAIDS.
• Patients must be willing to forego other cytotoxic and non-cytotoxic drug therapy for glioblastoma while enrolled in the study.
• Able to swallow oral medication.
• Patients ≥18 years of age at time of consent.
• Ability to understand and willingness to sign an informed consent form (ICF).
• Ability and stated willingness to adhere to the study visit schedule and protocol procedures/requirements, including periodic blood sampling and study related assessments
