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.

Brain Cancer Brain Neoplasm Glioma Glioblastoma Gliosarcoma Malignant Brain Tumor Neoplasm, Neuroepithelial Neuroectodermal Tumors Neoplasm by Histologic Type Neoplasm, Nerve Tissue Nervous System Diseases | Biological: DNX-2401 Biological: pembrolizumab | Phase 2 |
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.

Experimental: DNX-2401 + pembrolizumab
Intratumoral dose (1.0 mL) of DNX-2401 followed 7-9 days later by intravenous pembrolizumab, 200 mg, given every three weeks through 105 weeks (2 yrs.) or until progressive disease or unacceptable toxicity.

Biological: DNX-2401
On Day 0, following brain tumor biopsy and confirmation of recurrent tumor, a single injection of DNX-2401 is administered directly into the brain tumor.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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
- Karnofsky 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

- Tumor location in the brain stem
- Requires or, based upon history, may require treatment with high-dose systemic corticosteroids 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 HbA1c > 7%
- Previous treatment with any checkpoint inhibitor 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
