Immunotherapy or Targeted Therapy With or Without Stereotactic Radiosurgery for Patients With Brain Metastases From Melanoma or Non-small Cell Lung Cancer
USZ-STRIKE

Brief Summary
The primary objective of the study is to assess the efficacy in terms of CNS-specific PFS of the combination of standard systemic treatment plus SRS vs. standard systemic treatment alone in patients with newly diagnosed and untreated (except for surgery) asymptomatic or oligosymptomatic brain metastases from melanoma or NSCLC. This proposed randomised phase III clinical study addresses one of the most controversial issues in the current approach to patients with brain mets: the timing of SRS in patients eligible for systemic immune checkpoint inhibition or targeted therapy in order to guide therapeutic options as to what strategy allows the best compromise between best survival and best QoL.

Outcome Measures
Primary Outcomes (1)
CNS-specific PFS, locally assessed as per iRANO criteria
The primary objective of the study is to assess the efficacy in terms of CNS-specific progression-free survival (PFS) of the combination of standard systemic treatment plus SRS versus standard systemic treatment alone in patients with newly diagnosed and untreated (except surgery) asymptomatic or oligo-symptomatic brain metastases from melanoma or non-small cell lung cancer, with indication for systemic therapy.
from date of randomization until the date of documented CNS-specific progression, assessed up to 42 months
Study Arms (2)
Standard systemic treatment with stereotactic radiosurgery (SRS)
EXPERIMENTALArm A
Standard systemic treatment without stereotactic radiosurgery
ACTIVE COMPARATORArm B
Interventions
Systemic therapy follows the current standard of care, according to the type of the primary tumour. * For patients with melanoma, with or without BRAF-mutation, systemic therapy consists of * an approved immune-checkpoint inhibition combination therapy (cohort 1a) or * an approved immune-checkpoint inhibition monotherapy (cohort 1b). * For patients with NSCLC and a targetable oncogenic driver alteration (cohort 2a), systemic therapy consists of an approved targeted therapy (for example: EGFR-, ALK- or ROS1-targeted treatment). * For patients with NSCLC without a targetable oncogenic driver alteration (cohort 2b), systemic therapy consists of an approved immune-checkpoint inhibition therapy (with or without chemotherapy).
Depending on the investigator's preference, the following standard of care fractionation schedules are recommended: 1x 18-22 Gy, 3x 9 Gy or 5x 6 Gy. Fractionated stereotactic radiotherapy is favoured in principle, but not mandated, for postoperative radiotherapy and for metastases with a diameter of \>20 mm or for \>4 brain metastases. For patients randomised to Arm A, radiotherapy should be initiated within 14 days after randomisation.
Eligibility Criteria
You may qualify if:
- Newly diagnosed, previously untreated (except for surgery, see below) asymptomatic or oligo-symptomatic brain metastases, e.g., controlled symptomatic seizure disorder. Note: patients with neurological symptoms or signs that require more than a stable dose of 4 mg dexamethasone equivalent for more than one week are not considered oligo-symptomatic.
- Requirements for brain metastases:
- Brain metastases must be previously untreated, except for surgery.
- Prior surgery (including biopsies, resection, and cyst aspiration) for brain metastases is allowed. Residual and measurable disease after surgery is not required, but surgery must have confirmed the diagnosis. An MRI performed within 72 hours post-surgery should be available.
- Number and size of metastases at diagnosis of brain metastases:
- Maximum 1-10 brain metastases at screening
- At least one brain metastasis must be of ≥5 mm in diameter
- In case of 1-4 brain metastases:
- Longest diameter of largest brain metastasis must be ≤30 mm
- In case of 5-10 brain metastases:
- Largest metastasis must be ≤10 mL in volume and longest diameter must be ≤30 mm
- Maximum cumulative brain metastases volume must be ≤30 mL
- Primary disease of histologically confirmed (from primary tumour or from a metastatic lesion, including in the brain) melanoma or NSCLC
- Requirements for patients with melanoma:
- Prior treatment, including treatment with immune-checkpoint inhibitors is permitted, but brain metastases must be newly diagnosed and previously untreated (except for surgery).
- +11 more criteria
You may not qualify if:
- Confirmed or probable leptomeningeal metastases according to EANO ESMO criteria
- Symptomatic brain metastases at time of randomisation, e.g., neurological symptoms or signs that require more than a stable dose of 4 mg dexamethasone equivalent for more than one week.
- Patients must be off steroids or on a stable dose of ≤4 mg dexamethasone equivalent at randomisation.
- Patients experiencing seizures controlled by anti-epileptic drugs are eligible.
- Prior whole brain irradiation or focal radiation therapy to the brain
- Prior systemic treatment for brain metastases
- Contra-indication for SRS
- Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.
- Women who are pregnant or in the period of lactation.
- Sexually active men and women of childbearing potential who are not willing to use an effective contraceptive method during the study.
