Synergistic Treatment With Antiretrovirals and Laser Interstitial Thermal thErapy (STARLITE) for Unresectable High-Grade Gliomas: A Phase 1 Study
In Brief
A Phase 1 clinical trial evaluating Magnetic Resonance (MR)-guided Laser Interstitial Thermal Therapy (LITT), Abacavir, and 4 other interventions for High Grade Glioma. Currently recruiting, targeting 24 participants across 1 site.
Detailed Summary
The purpose of this study is to determine whether newly diagnosed high-grade glioma(s) that cannot be removed surgically change as a result of the study treatment; and to identify and evaluate the potential side effects (good and bad) of the study treatment in patients with newly diagnosed high-grade glioma(s) that cannot be removed surgically.
Study Details
Timeline
Arms & Interventions
Participants in this group will undergo Magnetic Resonance-guided Laser Interstitial Thermal Therapy (MR-guided LITT) on Day 0 after stereotactic needle biopsy. On Day 7, participants will begin combination antiretroviral therapy (ART) consisting of Abacavir, Lamivudine, and dose escalation/de-escalation of Ritonavir (RTV), to determine the recommended Phase 2 dose (RP2D) of Ritonavir. Participants will receive up to 12 months of ART. Beginning Day 14 through Day 180, participants will receive adjuvant therapy, standard of care consisting of focal radiotherapy and Temozolomide therapy. Participants will receive focal radiotherapy for six weeks (42 days). Participants will be administered Temozolomide up to Day 180. Participants will receive up to 12 months of study therapy, followed by up to 12 months of follow-up. Total participation duration is up to 24 months.

On Day 7, participants will begin combination antiretroviral therapy (ART) consisting of Abacavir, Lamivudine, and the recommended phase 2 dose (RP2D) of Ritonavir determined in Part 1. Participants will receive up to 12 months of ART. Beginning Day 14 through Day 180, participants will receive adjuvant therapy, standard of care consisting of focal radiotherapy and Temozolomide therapy. Participants will receive focal radiotherapy for six weeks (42 days), and Temozolomide therapy, during and following radiotherapy up to Day 180. Participants will receive up to 12 months of study therapy, followed by up to 12 months of follow-up. Total participation duration is up to 24 months. Total participation is approximately two years.
Interventions
Participants will be administered MR-guided Laser Interstitial Thermal Therapy (LITT) as a single procedure, following stereotactic needle biopsy.
Participants will take one 600mg tablet of Abacavir orally once daily, as part of combination antiretroviral therapy (ART).
Participants will take one 300mg tablet of Lamivudine orally once daily, as part of combination antiretroviral therapy (ART)
Participants will take one tablet of Ritonavir (RTV) orally twice daily, as part of combination antiretroviral therapy (ART), at one of the following dose levels: * Dose Level 1: 100mg * Dose Level 2 (starting dose): 300mg * Dose Level 3: 400mg * Dose Level 4: 600mg
Participants will take Temozolomide (TMZ) via capsule orally, during and after focal radiotherapy, as part of standard of care adjuvant therapy. During focal radiotherapy, Temozolomide will be administered at a dose of 75 mg/m2 once daily for six weeks (42 days) on a continuous dosing regimen, including weekends and holidays. After completion of focal radiotherapy, Temozolomide will be administered at 150 mg/m\^2 on days 1 through 5 of Cycle 1, and at 200 mg/m\^2 on days 1 through 5 of Cycles 2 through 6, for a total of six 28-day cycles of maintenance therapy.
Participants will be administered focal radiotherapy for six weeks (42 days), as part of adjuvant therapy, at a total dose of 50-60 grays (Gy) in 1.8-2.0 Gy fractions, depending on prognosis and as determined by the treating radiation oncologist.
