简要总结
This phase II trial studies how well genetic testing works in guiding treatment for patients with solid tumors that have spread to the brain. Several genes have been found to be altered or mutated in brain metastases such as NTRK, ROS1, CDK, PI3K, or KRAS G12C. Medications that target these genes such as abemaciclib, paxalisib, entrectinib and adagrasib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Genetic testing may help doctors tailor treatment for each mutation.
详细描述
PRIMARY OBJECTIVES:
I. To determine the activity of a CDK inhibitor in patients with progressive brain metastases derived from lung cancer, breast cancer, and other cancers harboring actionable genetic alterations associated with sensitivity to CDK inhibitors as measured by response rate (Response Assessment in Neuro-Oncology [RANO] criteria).
II. To determine the activity of a PI3K inhibitor in patients with progressive brain metastases derived from lung cancer, breast cancer, and other cancers harboring actionable genetic alterations in the PI3K pathway as measured by response rate (RANO criteria).
III: To determine the activity of an NTRK/ROS1 inhibitor in patients with progressive brain metastases derived from lung cancer harboring actionable NTRK/ROS1 gene fusions as measured by response rate (RANO criteria).
IV. To determine the activity of an KRAS G12C inhibitor in patients with progressive brain metastases derived from lung cancer, and other cancers harboring a KRAS G12C mutation as measured by response rate (RANO criteria).

入选标准
- •PRE-REGISTRATION ELIGIBILITY CRITERIA (ALL PATIENTS) • Tissue available for biomarker testing (any brain metastasis tissue and extracranial site from any prior resection or biopsy).
- •REGISTRATION ELIGIBILITY CRITERIA (ALL PATIENTS)
- •Participants must have histologically confirmed parenchymal metastatic disease to the brain from any solid tumor. Note: this includes patients that have controlled extracranial disease with progressive intracranial metastasis, as well as patients that have progressive intracranial and extracranial disease.
- •New or progressive brain metastases are defined as any one of the following:
- •Untreated measurable lesions in patients who have received surgery and/or stereotactic radiosurgery (SRS) to one or more other lesions.
- •Progressive measurable lesions after radiation, surgery, or prior systemic therapy
- •Residual or progressive lesions after surgery if asymptomatic.
- •Patients who have had prior whole-brain radiotherapy (WBRT) and/or SRS and then whose lesions have progressed by BM-RANO criteria or there are new lesions, are eligible. Lesions treated with SRS may be eligible if there is unequivocal evidence of progression. For patients with NTRK or ROS1 mutations, entrectinib may be used for newly diagnosed brain metastases. Similarly, for patients with KRAS G12C mutations, MRTX849 may be used for newly diagnosed brain metastases.
- •Patients who have not previously been treated with cranial radiation (e.g. WBRT or SRS) are eligible, but such patients must be asymptomatic or neurologically stable from their CNS metastases.
- •Measurable CNS disease (=> 10 mm).
- •Ability to obtain magnetic resonance imaging (MRI)s with contrast
- •No surgery within 2 weeks prior to or after registration.
- •No chemotherapy within 14 days prior to registration (Note: for abemaciclib arm, a 21-day chemotherapy washout is required).
- •For melanoma, patients must have progressed after prior immune checkpoint blockade or for BRAF positive melanoma, BRAF/MEK inhibitors.

- •Presence of clinically actionable alteration in NTRK, ROS1, KRAS G12C or CDK pathway or PI3K pathway in both a brain metastasis and extracranial site per central review.

For this arm, patients must have creatinine clearance ≥60 mL/min or glomerular filtration rate ≥60 mL/min/1.73m2 calculated using a validated prediction equation (e.g., Cockcroft-Gault, MDRD, or 24-hour urine CrCl).
- •No uncontrolled medical comorbidities per investigator discretion (e.g. interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment [e.g. estimated creatinine clearance <30ml/min], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea)
- •Radiation to symptomatic non-target sites within neural axis is allowed prior to registration without washout (provided there is at least one untreated target lesion for measurement on study and radiation is completed prior to registration).
- •Concurrent systemic corticosteroids are allowed if stable dose of dexamethasone for 7 days prior to registration. Baseline doses and changes in steroid dosing will be captured.
