- Surgical sterilization (i.e., tubal ligation or hysterectomy for women or vasectomy for men)
- 8.Patients must be able and willing to provide informed consent. A legally authorized representative (LAR) may provide consent if the potential subject lacks the capacity to provide consent themselves. Patient assent will be sought where feasible in this situation.
- 8.- For patients enrolled in Groups A and B, patients must be relapsed or refractory to standard of care therapy. Additionally, patients must continue with immunotherapy while undergoing oncolytic viral treatment at the discretion of the medical oncologist. 9. Patients enrolled in Group A or Group B must be on one of the following FDA approved immunotherapy agents: Ipilimumab, Nivolumab, Pembrolizumab, Relatlimab.
- 10. Normal hematologic, renal and liver function as defined by:

- AGC ≥1500/ mm3
- WBC ≥3000/mm3
- Platelets ≥100,000/ mm3
- PT, INR or PTT <1.5 x institutional upper limit
- Hemoglobin >8.0 g/dL
- Total serum bilirubin ≤ 1.5 upper normal institutional limits
- AST(SGOT)/ALT(SGPT) ≤2 × institutional upper limit of normal; ≤5 ULN if there is liver involvement secondary to the tumor
- Serum creatinine ≤ 1.5 x ULN OR
- ≥40 mL/min for participant with creatinine levels > 1.5 x institutional ULN
- (For Group A):
- Patients must have radiographic evidence of stable extracranial disease or no evidence of extracranial disease on current immunotherapy regimen based on RECIST v1.1 criteria.
- Patients must have between one and five brain metastases secondary to intracranial disease progression, identified on the screening MRI, from histologically confirmed metastatic melanoma. At least one of those lesions must be untreated, be suitable for accurate repeated measurements and have a tumor diameter of either 1.0-3.5cm (Group A- Arm 1) or 1.0-2.0cm (Group A- Arm 2) on the screening magnetic resonance imaging [MRI]) in at least one dimension. One of those lesions will be designated as the index lesion and planned for stereotactic intraoperative biopsy to ensure viable tumor tissue and oncolytic viral administration. The other four may be newly diagnosed, stable or recurrent.
- All intracranial metastases (the index lesion, and the non-index lesions, as defined below) must be located >5 mm from the optic chiasm and outside the brainstem.
- The brain metastases must be an independently verified measurable brain metastasis in accordance with the mRECIST (Appendix 1) by Neuro Radiology.
- Previous radiation and/or excision of brain metastases are permitted, provided that neurologic sequelae have completely resolved and at least one untreated lesion(s) remain.
- o Patients treated with SRS or surgical resection but who have one or more measurable lesion(s) that remained untreated will be eligible and the untreated lesions will be considered measurable target lesions.
- Patients in Group A will need to consent to have a biopsy of the intracranial index lesion taken at the time of the stereotactic oncolytic viral injection, before each injection of oncolytic virus. This is to obtain histologic confirmation of the tumor.
- For patients enrolled in Group A-Arm1, the index lesion must be surgically accessible for both stereotactic viral inoculation and surgical resection at the discretion of the treating neurosurgeon at the time of patient enrollment.
- For patients enrolled in Group A- Arm1, eligibility is restricted to patients who are undergoing surgical resection of the index lesion as part of standard of care of treatment.
- For patients enrolled into Group A- Arm 2, the index lesion must be surgically accessible for stereotactic viral inoculation at the discretion of the treating neurosurgeon. Amongst patients in DL2 or DL3 of Arm A.2, if the pre-treatment biopsy at the second or third viral inoculation does not demonstrate viable tumor, the patient will not receive further injections and for safety analysis will be considered to have not experienced a DLT at the number of serial doses administered.
- Index lesions in GroupA-Arm1 and GroupA-Arm2 that are located in or near eloquent cortex, as defined as the sensorimotor strip, speech and memory cortices, or proximity to corticospinal tracts, must be reviewed and approved by the enrolling neurosurgeon.
- Non-index lesions, which are not planned for oncolytic virus administration, must measure up to 4.0 cm in maximal extent on the screening MRI brain scan. The non-index lesion(s) can be treated with SRT or surgical resection at the discretion of the radiation oncologist and neurosurgeon.
- (For Group B):
- Patients must have radiographic evidence of progressive extracranial disease on current immunotherapy regimen based on RECIST v1.1 criteria.
- Patients enrolled in Group B must have at least 1 injectable extracranial lesion amenable for direct injection or through the use of image guidance, such as ultrasound. The lesion must be an injectable cutaneous, subcutaneous, or nodal melanoma lesion greater than or equal to 5mm in at least one dimension.
- Patients enrolled in Group B must have an injectable lesion that is not be adjacent or encasing vital structures such as an airway, major nerves or blood vessels, mucosal regions or spinal cord that, in the opinion of the Investigator, could cause occlusion or compression in the case of tumor swelling or erosion into a major vessel in the case of necrosis.
- Patients enrolled in Group B can have up to 5 intracranial metastases up to 4.0 cm in size; however, the presence of intracranial metastases is not a requirement for patients enrolled in this Arm. For patients with intracranial metastases, these lesions can be treated with SRT, surgical resection, or WBRT at the discretion of the radiation oncologist and neurosurgeon.
Who cannot join
- (For Both Groups):
- Patients with >5 diagnosed intracranial metastases on screening MRI
- Patients who received prior WBRT or SRT for brain metastases within 2 days of study treatment initiation
- Patients with symptomatic intracranial metastases
- Patients who received high dose corticosteroids defined as dexamethasone greater than 2mg per day within 7 days of initiating therapy. However, if they have been on a stable dose of 2 mg or less per day for 7 days they can be enrolled.
- Patients with suspected or confirmed leptomeningeal disease defined as radiographic evidence by MRI of leptomeningeal involvement in addition to positive cerebrospinal fluid (CSF) cytology

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing DNX-2401 in people with Melanoma, run by M.D. Anderson Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 42 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Christopher Alvarez-Breckenridge, MD, PHD ((713) 792-2400, calvarez11@mdanderson.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety and Adverse Events (AEs) (time frame: Through study completion; an average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
