Brief summary
To determine the safety and efficacy of using the drug azeliragon combined with stereotactic radiosurgery. Specifically, to determine if this combination will lead to improved response in the brain (tumor shrinking in size) and overall tumor control (how long tumor remains controlled).
Interventions
DRUGAzeliragon
Dosing will begin on Day 0 with the loading dose and continue daily through Day 7. Starting on Day 8, dosing will resume with the continuous dose until disease progression or 8 weeks. If there is evidence of antitumor effect at 8 weeks, dosing may continue for up 2 two years. All doses are taken orally. There are three levels of dosing, including a starting dose and two lower levels of dosing. Participants will start with the starting dose, and in the event of the dose limiting toxicities, the dose will be reduced as described below. Starting Dose Level: 30 mg twice daily (Loading Dose) or 20 mg once daily (Continuous Dose) Dose Level -1: 15 mg twice daily (Loading Dose) or 10 mg once daily (Continuous Dose) Dose Level -2: 15 mg once daily (Loading Dose) or 5 mg once daily (Continuous Dose)
RADIATIONStereotactic radiosurgery
Patients will undergo standard of care SRS as per the treating facility's policies.
DRUGCorticosteroid
Two corticosteroid regimens are used depending on the study cohort. Cohorts 1 and 2 will receive the loading dose (LD). Only Cohort 1 will receive the corticosteroid taper (CT). LD: Oral (8 mg) or IV bolus dose (10 mg) of dexamethasone or 40 to 80 mg of methylprednisolone on the day of SRS CT: Oral 2-4 mg of dexamethasone twice daily for 5 days and then 2-4 mg daily for 5 days at the discretion of the treating physician (concurrent use of a proton pump inhibitor or H2 receptor antagonists are encouraged during the CT).

Total bilirubin ≤ 1.5 × ULN. * Estimated creatinine clearance of \> 60 mL/min (per Cockcroft-Gault formula)
Exclusion criteria
1. Patients with leptomeningeal disease 2. Patients unable to undergo magnetic resonance imaging (MRI) 3. Patients receiving Cytochrome P450 (CYP) 2C8 inhibitors as indicated in the protocol 4. Patients with a gastrointestinal condition that could interfere with swallowing or absorption. 5. Females of childbearing potential who are sexually active or males with female partners of childbearing potential, where either the female or the male is unwilling to use a highly effective method of contraception during the trial and for 6 months after the last administration of azeliragon. 6. Patients with concurrent participation in another interventional clinical trial or use of another investigational agent within 7 days of starting azeliragon. Patients who are participating in non-interventional clinical trials (e.g., QOL, imaging, observational, follow-up studies, etc.) are eligible, regardless of the timing of participation. 7. Any patient that in the opinion of the principal investigator is not an appropriate candidate for this trial
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Dose-Limiting Toxicities (DLTs) | 4 weeks | A DLT of the azeliragon and corticosteroid regimen is defined as any central nervous system (CNS)-specific Grade ≥ 2 toxicity requiring corticosteroid treatment or any Grade ≥ 3 events that are not clearly due to the underlying disease or extraneous causes. DLTs will be considered up to four weeks after SRS. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CNS treatment-related adverse events | 24 months | Participants are evaluated for treatment-related adverse events (AEs). The total count of treatment-related AEs for all participants and those specifically in the central nervous system will be calculated. CNS treatment-related adverse events will be reported as percent of total treatment-related AEs. |
| Early brain metastases response rate | 8 weeks | Response and progression will be evaluated using the Response Assessment in Neuro-Oncology (RANO) criteria for brain metastasis (RANO-BM). The percent of patients with a complete response (CR) or partial response (PR) will be categorized individually and then together will be used to compare to the historical comparator of 24% with SRS alone. |
| Intracranial objective response rate | 6 months | Response and progression will be evaluated using RANO-BM. The percent of patients with CR, PR, or stable disease (SD) will be calculated. |
| Lesion-specific local tumor control rate | 6 months | Local failure will be defined using the following criteria: For lesions measuring more than 5 mm in the baseline (volumetric) scan: At least 50% increase in the product of the two largest perpendicular diameters (compared to the smallest product measured for the same lesion). For lesions measuring 5 mm or less in the baseline (volumetric) scan: At least 100% increase in the product of the two largest perpendicular diameters (compared to the smallest product measured for the same lesion). Radiation necrosis will not be considered tumor progression. Lesion-specific tumor control rate is defined as the percent of lesions that do not meet criteria for local failure as defined above. |
| Neurocognitive outcomes battery | 24 months | The following tests are included: * Hopkins Verbal Learning Test (HVLT) * Controlled Oral Word Association Test (COWAT) * Trail Making Test Part A * Trail Making Test Part B * Grooved Pegboard HVLT raw scores are derived for Total Recall, Delayed Recall, and Retention (% retained). COWAT is measured by summing the number of acceptable words produced for three separate letters during one minute each. The trail making tests are measured by the time they take to complete. The grooved pegboard is scored by the amount of time it takes to place the pegs correctly in the pegboard. Higher scores on HVLT and COWAT and faster times on the trail making and pegboard indicate better neurocognitive function. All tests are then standardized based on published norms and transformed so that higher values represent improved cognition. The endpoint is defined as a decline of greater than 1 standard deviation from baseline on at least 1 of the 5 neurocognitive tests. |
| Change in patient-reported outcomes (PROs) | Baseline to 24 months | PROs will be assessed using the MD Anderson Symptom Inventory for brain tumors (MDASI-BT), a validated assessment in people with brain metastases. It is a 28-item questionnaire that includes 13 symptom severity items, 6 symptom interference items, and 9 brain-tumor specific symptom items. Experience of each item "in the last 24 hours" is rated on a 10-point Likert scale where a higher score indicates worse outcomes. Ratings are averaged into several subscale scores: mean core symptom severity, mean brain tumor symptom severity, and mean interference. The change score from baseline to 24 months will be calculated by subtracting the 12-month overall score from the baseline overall score. Positive values indicate improved outcomes and negative values indicate worse outcomes. |
| Change in quality of life (QOL) using EORTC QLQ-C30 | Baseline to 24 months | European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 consists of 30 items and measures an individual's functioning and symptoms for all cancer types. Questions are grouped into 5 multi-item functional scales; 3 multi-item symptom scales; a 2-item global health status scale; 5 single items assessing additional symptoms commonly reported by cancer patients, and 1 item on the financial impact of the disease. Raw QLQ-C30 scores are transformed to standardized scores (0 to 100); a higher score represents a better level of functioning or a worse level of symptoms. A Summary Score is calculated from the mean of 13 of the 15 scales (excluding Global Quality of Life and Financial Impact scales). The symptom scales are reversed to obtain uniform direction of all scales. The change score from baseline to 24 months will be calculated by subtracting the 24-month score from the baseline score. Negative values indicate improved QOL. |
| Change in QOL using EORTC QLQ-BN20 | Baseline to 24 months | EORTC QLQ-BN 20 consists of 20 items and measures the functioning and symptoms of patients with intracranial malignant disease. Questions can be grouped into 3 multi-item functional scales (visual disorder, motor dysfunction, communication deficit), 7 single items (headaches, seizures, drowsiness, itchy skin, hair loss, weakness of legs and bladder control) and 1 multi-item scale on future uncertainty. Scoring is on a scale of 0 to 80, with higher scores indicating worse symptoms. The change score from baseline to 24 months will be calculated by subtracting the 24-month score from the baseline score. Positive values indicate improved symptoms. |
