A Phase 2, Multi-Center, Open-Label Study of a Conditionally Replicative Adenovirus, DNX-2401, with Pembrolizumab for Recurrent Glioblastoma or Gliosarcoma (CAPTIVE/KEYNOTE-192)


DNX-2401 (tasadenoturev) and pembrolizumab (MK3475) are investigational drugs for recurrent malignant brain cancers called glioblastoma and gliosarcoma. An investigational drug is one that the FDA and other health authorities have not approved to be safe and effective for the use being studied.

What is CAPTIVE?

CAPTIVE is a clinical study designed to investigate the efficacy and safety of DNX-2401 with pembrolizumab as a potential treatment for recurrent glioblastoma. Investigational study sites are currently screening patients in the US and Canada for participation in the CAPTIVE/KEYNOTE-192 study.

What is DNX-2401?

DNX-2401 is an investigational drug that is a modified adenovirus (common cold virus), which has been designed to specifically and selectively infect and attack cancer cells, but not normal cells.

DNX-2401 has been studied in over 150 patients in 6 clinical trials for cancer.

How does it work?

After DNX-2401 infects tumor cells, it multiplies and causes tumor cell death. The dying tumor cell releases signals that stimulate the immune system to attack and kill additional tumor cells. The new copies of DNX-2401 infect more tumor cells, leading to a chain reaction of tumor cell killing.

What is pembrolizumab?

Pembrolizumab, also known as KEYTRUDA,® is a monoclonal antibody that has already been approved by the FDA for use in some patients with advanced melanoma and certain patients with non-small cell lung cancer. Monoclonal antibodies are a type of targeted cancer therapy. Pembrolizumab is developed by Merck & Co., Inc.

How does it work?

Pembrolizumab is a selective antibody directed against the PD-1 receptor, a protein on the cell surface. Pembrolizumab blocks the PD-1 receptor and prevents the activation of proteins PD-L1 and PD-L2, which causes activation of an immune response against tumor cells.


The purpose of this study is to investigate the safety and efficacy of using DNX-2401 and pembrolizumab together for the treatment of recurrent glioblastoma.

You may qualify for the CAPTIVE study if you:

  • Are at least 18 years old
  • Have been diagnosed with a first or second recurrence of glioblastoma or gliosarcoma
  • Have a tumor that measures between 1-4 cm (up to 1½ inches) in longest diameter
  • Have a tumor for which resection (brain surgery) is not possible or planned
