Um Estudo de Fase 1 de Segurança e Determinação de Dose do GLIX1 em Adultos com Glioma de Alto Grau Recorrente ou Progressivo
Um Estudo Aberto de Fase 1 para Avaliação de Segurança e Determinação de Dose de GLIX1 Administrado por Via Oral em Adultos com Glioma de Alto Grau Recorrente ou Progressivo
This is an open-label, multicenter dose-escalation study to be followed by a dose expansion to define the optimal dose of GLIX1 as monotherapy by reviewing safety and tolerability, disease characteristics and pharmacokinetic profiles and preliminary clinical activity in participants with a high grade diffuse glioma that progressed during or recurred after prior standard of care therapies or investigational therapies as clinically indicated.
Patients will be treated daily with GLIX1 capsules until disease progression or unacceptable safety.

Descrição detalhada
Glioblastomas (GBMs) are the most common and aggressive primary malignant tumors in adult central nervous system. High-grade glioma almost always recur and/or progress, and upon progression treatment options are very limited with no universal standard therapy established.
GLIX1 is a small molecule administered PO (per os, i.e., orally), that targets the deoxyribonucleic acid (DNA) damage repair mechanism by enhancing Tet methylcytosine dioxygenase 2 (TET2) activity. Increasing the activity of the TET2 enzyme increases DNA oxidation at 5-methylcytosine residues. Such oxidation is normally processed by base excision repair. During base excision repair, a single stranded DNA break is formed. These single strand DNA breaks are well tolerated in normal cells. In cancer, alterations in DNA methylation are common and TET2 activity is inhibited, giving rise to increased DNA methylation in close genomic proximity. When GLIX1 agonizes TET2 activity in cancer cells, excessive base excision repair results in numerous single strand DNA breaks in close proximity, which ultimately converge to form double strand DNA breaks that overwhelm the repair capacity of these cancer cells, resulting in apoptotic cell death.
High-grade glioma have some of the lowest levels of genomic 5-hydroxymethylcytosine. Thus, enhancing the activity of the TET2 enzyme in these cells is likely to have the greatest effect in terms of treating cancers.
Indeed, GLIX1 has been shown to cross the blood brain barrier in rodents and has shown significant activity in various in vitro and in vivo GBM and glioma tumor models.
