Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

NBM-BMX is an orally available new chemical entity to inhibit histone deacetylases 8 (HDAC8) activity specifically, being developed as a potential anti-cancer therapeutic by NatureWise. This study aims to evaluate the safety, pharmacokinetics, and preliminary efficacy of NBM-BMX as monotherapy in subjects with advanced solid tumors or combination with the standard of care treatment in subjects with newly diagnosed glioblastoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
