Imaging Perfusion Restrictions From Extracellular Solid Stress - An Open-label Losartan Study (ImPRESS)

Study Description
Brief Summary:
An open-label, single institutional phase II trial of losartan in patients with primary and metastatic brain tumors with an individual stepped-wedge, randomized, assessor-blinded, dose-finding design on three indications.

Condition or disease Intervention/treatment Phase
Glioblastoma Brain Metastases Drug: Losartan Phase 2

Detailed Description:

For this study losartan, an angiotensin-II inhibitor, is defined as the Investigational Medicinal Product (IMP). The focus of the study is to assess the dose-response relationship of losartan on imaging-based measures of tissue perfusion and mechanical forces in patients with brain tumors. We hypothesize that losartan improves the effect of traditional cancer treatment by alleviating mechanical forces (solid stress) of the tumor microenvironment to improve tissue perfusion, while administration of losartan alone has little effect on cancer patients.

This is an open-label study and no active comparator or placebo will be used. Study participants include adult patients with newly diagnosed- and recurrent glioblastoma, as well as adult patients with metastatic brain tumors from non-small cell lung cancer. The study will assess the safety of losartan treatment and its dose-response relationship on conventional and experimental radiographic characteristics when used alone or as an add-on to standard cancer treatment.

Arms and Interventions
Arm Intervention/treatment
Experimental: Study A: Recurrent glioblastoma (denoted 'AR')

Patients with recurrent glioblastoma (N=54) with be randomized (ratio 1:1:1) to doses of 25mg, 50mg or 100mg daily of losartan while on treatment. Losartan (tablet) will be administered every day, with 2 weeks (14 consecutive days) defined as a treatment cycle. Based on randomization, a minimum of three cycles and a maximum of 12 cycles will be administered for a total of 6 weeks (42 days) to 24 weeks (168 days), respectively. Patients randomized to 100mg of losartan will all receive treatment for the maximum duration.

A stepped-wedge randomized design (ratio 1:1:1 for all doses over the three first cycles) is proposed to compare participants on- and off- study IMP and assess any dose-response relationship losartan. This study arm will also investigate any additional long-term beneficial effects of losartan while receiving chemotherapy (temozolomide or lomustine tablets).

 Drug: Losartan
This trial is open-label; therefore, the participant, the trial site personnel, the Sponsor and/or designee are not blinded to treatment. Drug identity (name, strength) is included in the label text. Storage, handling and preparation requirements will be handled in concordance with the Pharmacy Manual for losartan.
Experimental: Study A: Newly diagnosed glioblastoma (denoted 'AN')

Patients with newly diagnosed glioblastoma (N=54) with be randomized (ratio 1:1:1) to doses of 25mg, 50mg or 100mg daily of losartan while on treatment. Losartan (tablet) will be administered every day, with 2 weeks (14 consecutive days) defined as a treatment cycle. Based on randomization, a minimum of three cycles and a maximum of 17 cycles will be administered for a total of 6 weeks (42 days) to 34 weeks (238 days), respectively. Patients randomized to 100mg of losartan will all receive treatment for the maximum duration.

A stepped-wedge randomized design (ratio 1:1:1 for all doses over the three first cycles) is proposed to compare participants on- and off- study IMP and assess any dose-response relationship losartan.

Descriptive Information
Brief Title  ICMJE Imaging Perfusion Restrictions From Extracellular Solid Stress - An Open-label Losartan Study
Official Title  ICMJE Imaging Perfusion Restrictions From Extracellular Solid Stress - An Open-label Losartan Study
Brief Summary An open-label, single institutional phase II trial of losartan in patients with primary and metastatic brain tumors with an individual stepped-wedge, randomized, assessor-blinded, dose-finding design on three indications.
Detailed Description

For this study losartan, an angiotensin-II inhibitor, is defined as the Investigational Medicinal Product (IMP). The focus of the study is to assess the dose-response relationship of losartan on imaging-based measures of tissue perfusion and mechanical forces in patients with brain tumors. We hypothesize that losartan improves the effect of traditional cancer treatment by alleviating mechanical forces (solid stress) of the tumor microenvironment to improve tissue perfusion, while administration of losartan alone has little effect on cancer patients.

This is an open-label study and no active comparator or placebo will be used. Study participants include adult patients with newly diagnosed- and recurrent glioblastoma, as well as adult patients with metastatic brain tumors from non-small cell lung cancer. The study will assess the safety of losartan treatment and its dose-response relationship on conventional and experimental radiographic characteristics when used alone or as an add-on to standard cancer treatment.

Study Arms  ICMJE
  • Experimental: Study A: Recurrent glioblastoma (denoted 'AR')

    Patients with recurrent glioblastoma (N=54) with be randomized (ratio 1:1:1) to doses of 25mg, 50mg or 100mg daily of losartan while on treatment. Losartan (tablet) will be administered every day, with 2 weeks (14 consecutive days) defined as a treatment cycle. Based on randomization, a minimum of three cycles and a maximum of 12 cycles will be administered for a total of 6 weeks (42 days) to 24 weeks (168 days), respectively. Patients randomized to 100mg of losartan will all receive treatment for the maximum duration.

    A stepped-wedge randomized design (ratio 1:1:1 for all doses over the three first cycles) is proposed to compare participants on- and off- study IMP and assess any dose-response relationship losartan. This study arm will also investigate any additional long-term beneficial effects of losartan while receiving chemotherapy (temozolomide or lomustine tablets).

    Intervention: Drug: Losartan
  • Experimental: Study A: Newly diagnosed glioblastoma (denoted 'AN')

    Patients with newly diagnosed glioblastoma (N=54) with be randomized (ratio 1:1:1) to doses of 25mg, 50mg or 100mg daily of losartan while on treatment. Losartan (tablet) will be administered every day, with 2 weeks (14 consecutive days) defined as a treatment cycle. Based on randomization, a minimum of three cycles and a maximum of 17 cycles will be administered for a total of 6 weeks (42 days) to 34 weeks (238 days), respectively. Patients randomized to 100mg of losartan will all receive treatment for the maximum duration.

    A stepped-wedge randomized design (ratio 1:1:1 for all doses over the three first cycles) is proposed to compare participants on- and off- study IMP and assess any dose-response relationship losartan. This study arm will also investigate any additional long-term beneficial effects of losartan while receiving adjuvant chemotherapy (Temozolomide tablets).

    Intervention: Drug: Losartan
  • Experimental: Study B: Brain metastases (denoted 'BM')

    Patients with brain cancer from non-small cell lung cancer (N=45) with all receive a dose of 50mg daily of losartan while on treatment. Losartan (tablet) will be administered every day, with 3 months (90 consecutive days) defined as a treatment cycle. A minimum of one cycle and a maximum of three cycles will be administered for a total of 3 months (90 days) to 9 months (270 days), respectively.

    A stepped-wedge randomized design (ratio 1:1:1 over the three first cycles) is proposed to compare participants on- and off- study IMP and assess any dose-response relationship losartan. This study arm will also investigate any additional long-term beneficial effects of losartan while receiving chemotherapy alone (carboplatin in combination with vinorelbin or pemetrexed or equivalent analogs) or in combination with pembrolizumab (2mg/kg/3rd week).
