NBM-BMX Administered Orally to Patients With Solid Tumors or Newly Diagnosed Glioblastoma

This is a multi-center, open-label, 2-arm, phase Ib/II study to evaluate the safety, pharmacokinetics, and preliminary efficacy of NBM-BMX as monotherapy in the treatment of solid tumors (Arm A) or in combination with radiotherapy/temozolomide in the treatment of glioblastoma (Arm B). Arm A consists of dose escalation cohorts in subjects with advanced solid tumors who will be treated with NBM-BMX monotherapy at different dose levels. Arm B consists of dose escalation cohorts (Phase Ib) and expansion cohorts (Phase II) in subjects with newly diagnosed glioblastoma (GBM). Subjects will be treated with NBM-BMX at different dose levels in combination with the first-line standard of care treatment (i.e., concomitant Radiotherapy (RT)/TMZ followed by adjuvant TMZ) in Phase Ib. After the recommended Phase 2 dose (RP2D) is determined in Phase Ib, additional subjects will be enrolled and treated at the RP2D to evaluate the efficacy of NBM-BMX combination therapy.
