A Trial for Treatment of Cancer Patients With Multiple Brain Metastases Undergoing Whole-Brain Radiotherapy
Study Details
Study Description
Brief Summary
This protocol is for a lead-in safety study of 5 patients followed by a randomized Phase 2 clinical trial of BMX-001, a new class of pharmaceutical, in 64 patients with multiple brain metastases (MBM) undergoing whole brain radiation therapy (WBRT). Preliminary studies have demonstrated that BMX-001 provides protection of normal tissues from radiation-induced injury and augments tumor growth inhibition.

Phase 1/Phase 2 |
Detailed Description
This protocol is for a Phase 1 safety lead-in clinical trial of BMX-001 in combination with WBRT in 5 patients with MBM. Demonstrating safety of the selected MTD of BMX-001 in patients with MBM undergoing standard protocol WBRT will be the "go/no-go" criteria for proceeding to Phase 2.
Phase 2 is a randomized open-label Phase 2 clinical trial of 64 patients with MBM, half receiving BMX-001 in combination with WBRT and half receiving WBRT alone.
Subjects are treated with BMX-001 for a total of 19 days, during which time they receive radiation therapy. Following completion of radiation therapy, subjects will be followed for an additional one year.

Outcome Measures
Primary Outcome Measures
- Assess safety and tolerability of WBRT + BMX-001 through proportion of patients who experience grade 4 or 5 study drug related adverse events. [1 year]
AEs will be assessed according to the CTCAE version 5.0. If CTCAE grading does not exist for an AE, the severity of the AE will be graded as mild (1), moderate (2), severe (3), life-threatening (4), or fatal (5). Initially 5 patients will be accrued and treated with WBRT + BMX-001 as a lead-in safety phase. Enrollment to the randomized phase of the study will not proceed if patients in the safety lead-in phase experience the following: Two or more patients are unable to complete radiation therapy (RT) due to toxicity related to BMX-001 (alone or in combination with RT. Two or more patients experience delay in starting RT due to toxicity related to BMX-001 (alone or in combination with RT). If any patient experiences a grade 4 or 5 BMX-001-related adverse event within Arm A (WBRT + BMX-001), accrual will be suspended and the experience of the patient will be carefully reviewed by the clinical team and the study's DSMB.
- Compare neurocognition in WBRT + BMX-001 vs. WBRT alone using cumulative score of HVLT-R, TMT A&B and COWA over time. [1 Year]
Subjects will complete three standardized tests (Hopkins Verbal Learning Test - Revised, Trail Making Test A&B, and Controlled Oral Word Association test) at baseline, 1 month after completion of WBRT and every 3 months after completion of WBRT. The cumulative score of these three tests will be used to assess change.
Secondary Outcome Measures
- Compare survival in WBRT + BMX-001 vs WBRT alone [1 Year]
Survival
- Compare local recurrence rate in WBRT + BMX-001 vs WBRT alone [1 Year]
Median time to local brain failure or progression
- Compare distant brain failure rate in WBRT + BMX-001 vs WBRT alone [1 Year]
Median time to distant brain failure
- Compare rate of neurologic death in WBRT + BMX-001 vs WBRT alone [1 Year]
Proportion of patients who are dead within 1 year of initiation of WBRT due to neurologic disease and/or disseminated leptomeningeal carcinomatosis.
Other Outcome Measures
- Compare rate of radionecrosis in WBRT + BMX-001 vs WBRT alone [1 Year]
Proportion of patients with enlarged and/or symptomatic brain lesions with no viable tumor on biopsy
- Compare QoL in WBRT + BMX-001 vs WBRT alone [1 Year]
Mean change from baseline at each follow-up assessment

-
Serum creatinine ≤ 1.5 mg/dl, serum SGOT and bilirubin ≤ 1.5 times upper limit of normal
-
Signed informed consent approved by the Institutional Review Board
-
If sexually active, patients must agree to use appropriate contraceptive measures for the duration of the study and for 6 months afterwards as stated in the informed consent
-
Able to provide study specific informed consent
-

Exclusion Criteria:

-
Subjects receiving prohibited medications listed in Section 6.4.2 of this protocol are not eligible. Subjects who can safely stop taking a prohibited medication at least 7 days prior to the first dose of BMX may participate at the discretion of the treating physician.
