Safety of Fluvastatin-Celebrex Association in Low-grade and High Grade Optico-chiasmatic Gliomas

• Status: Active, not recruiting
• Trial end date: 2022-10-01
• Target enrollment: 0
• Participant gender: All

Summary

Optico-chiasmatic gliomas have therapeutic feature since surgical resection plays a secondary role. Unlike other sites, many of these tumors are not amenable to complete resection either because of anatomical location, and sometimes they only can be biopsied. A substantial number of children will have recurrences following resection or will experience progression following incomplete tumor removal or biopsy.

Celebrex is a Cox-2 inhibitor with anti-angiogenic and anti-tumor properties, while statins are known to increase the sensitivity of gliomas to anti-tumor agents. Their association could be administered for long periods, in the hope of much reduced risk of toxicities.

This is a national, multicentric, interventional, open-label, non-comparative, and non-randomized phase I study evaluating the maximum tolerated dose of the Fluvastatin in combination with fixed-dose of Celebrex.

This project involves 10 SFCE health centers accustomed to phase I / II studies(Société Française de Lutte contre les Cancers et Leucémies de l'Enfant et de l'Adolescent - French Society for the Fight against Cancer and Leukemia in Children and Adolescents).
