Study summary

Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase II study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified oncolytic adenovirus, when delivered directly into the tumor followed by the administration of intravenous pembrolizumab (an immune checkpoint inhibitor) given every 3 weeks for up to 2 years or until disease progression.

Read the detailed description

In the initial phase of the study, up to 12 evaluable subjects will be enrolled in 3 dose cohorts to determine the best dose of DNX-2401, as follows:

  • Cohort 1: Single dose DNX-2401 (5e8 vp) delivered intratumorally by cannula, followed by intravenous pembrolizumab every 3 weeks (Q3W)
  • Cohort 2: Single dose DNX-2401(5e9 vp) delivered intratumorally by cannula, followed by intravenous pembrolizumab every 3 weeks (Q3W)
  • Cohort 3: Single dose DNX-2401 (5e10 vp) delivered intratumorally by cannula, followed by intravenous pembrolizumab every 3 weeks (Q3W)

Following the initial phase, up to 36 additional subjects diagnosed with recurrent glioblastoma or gliosarcoma will be enrolled to receive a single of DNX-2401 determined in the initial phase administered intratumorally followed by intravenous pembrolizumab every 3 weeks.

All subjects will return to the clinic for study follow-up visits at regular intervals for safety monitoring, MRI scans and other assessments, for up to 2 years or until disease progression. All subjects will be followed closely for safety and survival.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • A single glioblastoma or gliosarcoma tumor with histopathological confirmation for first or presenting second recurrence of glioblastoma or gliosarcoma at the time of consent
  • Gross total or partial tumor resection is not possible or not planned
  • A single measurable tumor that is at least 10.0 mm longest diameter (LDi) X 10.0 mm shortest diameter (SDi) and this tumor does not exceed 40.0 mm in LDi or SDi on Screening MRI
  • Tumor recurrence or progression documented after previously failing surgical resection, chemotherapy or radiation
  • performance status ≥ 70 %
  • Prior anti-tumor therapies must have been completed within time periods specified in the protocol prior to DNX-2401 injection and toxic side effects must be mild, if present
  • Demonstrate adequate organ function via specified laboratory test results

Exclusion criteria

Exclusion Criteria:

  • Multiple (≥ 2) separate enhancing tumors
  • Tumor location on both sides of the brain and/or involvement that would present the risk of injecting DNX-2401 into the ventricles of the brain
  • Tumor location in the brain stem
  • Requires or, based upon history, may require treatment with high-dose systemic within 2 weeks of the start of intravenous pembrolizumab infusions and within 2 weeks following the first infusion of pembrolizumab
  • Uncontrolled blood-sugar levels defined as > 7%
  • Previous treatment with any such as anti-PD1 or PD-L1 agents including pembrolizumab (KEYTRUDA) or any other checkpoint inhibitor(s) (e.g., ipilimumab, nivolumab, etc.)
  • History of (non-infectious) or current active pneumonitis that required steroids and/or a history of interstitial lung disease
  • Prior gene transfer therapy or prior therapy with a cytolytic virus of any type
  • Brain tumor that is not measurable on MRI or persons who are unable to have MRIs
  • Pregnant or nursing females

Note: Other protocol-defined inclusion and exclusion criteria may apply as outlined in the relevant protocol version

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2016 to primary completion in Mar 2021, 53 months.

Of 44 industry-sponsored phase 2 interventional studies under Brain Neoplasms, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 55. This study's 53 months is above that.

Counting every sponsor, half of 252 studies reached it within 61 months; a quarter within 38 and three quarters within 98.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 15, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
