What this trial studies

This Phase 1 study aims to determine the maximum tolerated dose, safety, and efficacy of BEY1107 when combined with Temozolomide in patients suffering from recurrent or progressive glioblastoma multiforme (GBM). Participants will be adults who have not responded to standard treatments and will be enrolled at various dose levels of BEY1107. The study will assess the treatment's effects on measurable lesions according to established criteria. The goal is to find a potentially effective new treatment option for this challenging condition.

Who should consider this trial

Good fit: Ideal candidates are adults over 19 years old with recurrent or progressive GBM who have not responded to standard care.

Not a fit: Patients with stable GBM who have not progressed or those who have not failed standard treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with recurrent glioblastoma multiforme who have limited choices.

How similar studies have performed: Other studies have explored similar combinations for GBM, but the specific approach of BEY1107 with Temozolomide is novel.
