What You Need to Know Before You Apply

What is the purpose of this trial?

This is a phase IB/II, open-label study evaluating CTX-009 as monotherapy and in combination with CTX-471. The study evaluates the safety and efficacy of the monotherapy and the combination in patients with recurrent glioblastoma. The study tests the hypothesis that treatment with CTX-009 alone or in combination with CTX-471 will lead to enhanced tumor control and prolongation of overall survival of patients with recurrent glioblastoma.

CTX-009 expands on existing anti-angiogenic therapies by ablating key compensatory and resistance mechanisms to bevacizumab, CTX-471 restores local immune reactivity through activation of costimulatory immune mediators. Combination of these two agents may further impair tumor proliferation through synergistic effects on the tumor microenvironment

Trial Overview

The study is testing CTX-009 alone or combined with CTX-471 to see if they can better control tumor growth and extend survival in recurrent glioblastoma patients. It's an early-stage trial (phase IB/II) that's open-label, meaning everyone knows which treatment they're getting.
