About this study
Official title: Phase I/II Intratumoral Administration of Hu14.18-IL2, With Local Radiation, Nivolumab and Ipilimumab in Subjects With Advanced Melanoma
This phase I/II trial is designed to determine the maximum tolerated dose or the maximum administered dose of intratumoral administration of hu14.18-IL2 and to evaluate side effects of intratumoral hu14.18-IL2 when given alone, after radiation therapy, after radiation therapy and in combination with nivolumab, and after radiation therapy and in combination with nivolumab and ipilimumab in patients with melanoma that is advanced (stage IV) or with melanoma that cannot be removed by surgery and is considered surgically incurable. Hu14.18-IL2 is a molecule called a fusion protein that can bind to some tumor cells and cause immune cells to become activated to kill tumor cells. Radiation therapy is a type of cancer treatment that uses beams of high energy x-rays to kill tumor cells and shrink tumors. Immunotherapy with immune checkpoint inhibitors, such as nivolumab and ipilimumab, can help the body's immune system attack cancer by releasing the "brakes" on the immune system to allow cancer fighting immune cells to remain activated. This study will evaluate whether giving intratumoral hu14.18-IL2 with radiation therapy, nivolumab and ipilimumab has antitumor activity for participants with advanced melanoma.
After completion of study treatment, participants are followed up at 30 days, every 12 weeks for up to 2 years, and then every 6 months thereafter.

II. Evaluate pathologic (tissue) evidence of immune response at the injection site and untreated sites.
III. Evaluate PFS, CB and duration of response to hu14.18-IL2 in combination with palliative RT, nivolumab and ipilimumab based on resistance to prior treatment with anti-CTLA-4 and/or anti PD1/PD-L1 antibody.
IV. Evaluate serial serum samples to determine the pharmacokinetics of hu14.18-IL2 administered intratumorally.
- Evaluate each subject's tumor cells for expression of GD2 and PD-L1, and determine if either antitumor activity or selected treatment-associated biologic effects are more likely for tumors that are GD2+ then GD2- and PD-L1+ than PD-L1-.
VI. Evaluate whether PD-L1 expression is induced or augmented from baseline following initiation of treatment (by comparing serial biopsies).
VII. Evaluate the immunologic activation induced in vivo by IT-hu14.18-IL2, addressed by in vitro cellular, serologic and flow cytometry immune assays.
VIII. Evaluate for histological evidence of antitumor activity based on the presence of necrotic tumor cells, inflammatory infiltrate, cellular phenotype of infiltrate, and presence of hu14.18-IL2 within the tumor at selected post-treatment timepoints.
IX. Evaluate circulating tumor cells, exosomes, endogenous antibodies, and/or deoxyribonucleic acid (DNA) as exploratory biomarkers associated with clinical response to IT-hu14.18-IL2 in combination with RT, nivolumab and ipilimumab.
- Evaluate serial peripheral blood mononuclear cell (PBMC) samples to monitor the induction of T cell responses to melanoma-associated antigens.
XI. Evaluate objective tumor responses, both locally and systemically (by immune-related response criteria), in Phases IA, IB and IC of this trial (involving IT-hu14.18-IL2 alone and in combinations with palliative RT, and with palliative RT and nivolumab, respectively).
OUTLINE: This is a dose escalation study of hu14.18-IL2 fusion protein.
PHASE IA: Participants receive hu14.18-IL2 fusion protein intratumorally (IT) once daily (QD) on days 1-3. Treatment repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. A total of 9-18 participants will be enrolled in 3 escalating dose levels to determine the Maximum Tolerated Dose (MTD)/Maximum Administered Dose (MAD) of hu14.18-IL2 in Phase IA.
PHASE IB: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT will be determined starting 1 dose level below the Phase IA determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IA determined MTD/MAD.
PHASE IC: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Nivolumab (3 mg/kg) is given every 2 weeks for up to 1 year with the initial dose given between day -7 and day -1 of cycle 1. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT in combination with nivolumab will be determined starting 1 dose level below the Phase IB determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IB determined MTD/MAD.
PHASE ID: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Nivolumab (1 mg/kg) in combination with ipilimumab (3 mg/kg) is given every 3 weeks for 4 cycles with the initial dose given between day -7 and day -1 of cycle 1. Following 4 cycles, no additional ipilimumab will be administered. Following cycle 4, maintenance nivolumab (3 mg/kg) can be given for up to one year. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT in combination with nivolumab and ipilimumab will be determined starting 1 dose level below the Phase IC determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IC determined MTD/MAD. A total of 28 participants will be enrolled at the Phase ID MTD/MAD of IT-hu14.18-IL2.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This phase I/II trial is designed to determine the maximum tolerated dose or the maximum administered dose of intratumoral administration of hu14.18-IL2 and to evaluate side effects of intratumoral hu14.18-IL2 when given alone, after radiation therapy, after radiation therapy and in combination with nivolumab, and after radiation therapy and in combination with nivolumab and ipilimumab in patients with melanoma that is advanced (stage IV) or with melanoma that cannot be removed by surgery and is considered surgically incurable. Hu14.18-IL2 is a molecule called a fusion protein that can bind to some tumor cells and cause immune cells to become activated to kill tumor cells. Radiation therapy is a type of cancer treatment that uses beams of high energy x-rays to kill tumor cells and shrink tumors. Immunotherapy with immune checkpoint inhibitors, such as nivolumab and ipilimumab, can help the body's immune system attack cancer by releasing the "brakes" on the immune system to allow cancer fighting immune cells to remain activated. This study will evaluate whether giving intratumoral hu14.18-IL2 with radiation therapy, nivolumab and ipilimumab has antitumor activity for participants with advanced melanoma.
After completion of study treatment, participants are followed up at 30 days, every 12 weeks for up to 2 years, and then every 6 months thereafter.

SECONDARY OBJECTIVES:
- Evaluate progression-free survival (PFS), overall survival (OS), clinical benefit (CB, defined as complete response (CR) + partial response (PR) + stable disease (SD)) and duration of response to hu14.18-IL2 in combination with RT, nivolumab and ipilimumab.
II. Evaluate pathologic (tissue) evidence of immune response at the injection site and untreated sites.
III. Evaluate PFS, CB and duration of response to hu14.18-IL2 in combination with palliative RT, nivolumab and ipilimumab based on resistance to prior treatment with anti-CTLA-4 and/or anti PD1/PD-L1 antibody.
IV. Evaluate serial serum samples to determine the pharmacokinetics of hu14.18-IL2 administered intratumorally.
- Evaluate each subject's tumor cells for expression of GD2 and PD-L1, and determine if either antitumor activity or selected treatment-associated biologic effects are more likely for tumors that are GD2+ then GD2- and PD-L1+ than PD-L1-.
VI. Evaluate whether PD-L1 expression is induced or augmented from baseline following initiation of treatment (by comparing serial biopsies).
VII. Evaluate the immunologic activation induced in vivo by IT-hu14.18-IL2, addressed by in vitro cellular, serologic and flow cytometry immune assays.
VIII. Evaluate for histological evidence of antitumor activity based on the presence of necrotic tumor cells, inflammatory infiltrate, cellular phenotype of infiltrate, and presence of hu14.18-IL2 within the tumor at selected post-treatment timepoints.
IX. Evaluate circulating tumor cells, exosomes, endogenous antibodies, and/or deoxyribonucleic acid (DNA) as exploratory biomarkers associated with clinical response to IT-hu14.18-IL2 in combination with RT, nivolumab and ipilimumab.
- Evaluate serial peripheral blood mononuclear cell (PBMC) samples to monitor the induction of T cell responses to melanoma-associated antigens.
XI. Evaluate objective tumor responses, both locally and systemically (by immune-related response criteria), in Phases IA, IB and IC of this trial (involving IT-hu14.18-IL2 alone and in combinations with palliative RT, and with palliative RT and nivolumab, respectively).
OUTLINE: This is a dose escalation study of hu14.18-IL2 fusion protein.
PHASE IA: Participants receive hu14.18-IL2 fusion protein intratumorally (IT) once daily (QD) on days 1-3. Treatment repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. A total of 9-18 participants will be enrolled in 3 escalating dose levels to determine the Maximum Tolerated Dose (MTD)/Maximum Administered Dose (MAD) of hu14.18-IL2 in Phase IA.
PHASE IB: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT will be determined starting 1 dose level below the Phase IA determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IA determined MTD/MAD.
PHASE IC: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Nivolumab (3 mg/kg) is given every 2 weeks for up to 1 year with the initial dose given between day -7 and day -1 of cycle 1. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT in combination with nivolumab will be determined starting 1 dose level below the Phase IB determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IB determined MTD/MAD.
PHASE ID: Participants undergo palliative RT on days -8 to -4 of cycle 1 only. Nivolumab (1 mg/kg) in combination with ipilimumab (3 mg/kg) is given every 3 weeks for 4 cycles with the initial dose given between day -7 and day -1 of cycle 1. Following 4 cycles, no additional ipilimumab will be administered. Following cycle 4, maintenance nivolumab (3 mg/kg) can be given for up to one year. Participants also receive hu14.18-IL2 fusion protein IT as in phase IA. Treatment with hu14.18-IL2 repeats every 21 days for cycles 1-4. Participants who are eligible may continue to receive hu14.18-IL2 fusion protein maintenance therapy QD on days 1-3 beginning with cycle 5. Maintenance cycles repeat every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. The MTD/MAD of IT-hu14.18-IL2 following palliative RT in combination with nivolumab and ipilimumab will be determined starting 1 dose level below the Phase IC determined MTD/MAD of IT-hu14.18-IL2 up to the Phase IC determined MTD/MAD. A total of 28 participants will be enrolled at the Phase ID MTD/MAD of IT-hu14.18-IL2.

Primary outcome
Incidence of Adverse Events
Time frame: up to 2 years
The number and severity of toxicity incidents per (Common Terminology Criteria for Adverse Events (CTCAE) v 5.0 will be summarized with frequency and proportion. The 95% confidence interval for the proportion of subjects with severe complications (grade 3 or higher toxicities) will be constructed.
Maximum Tolerated Dose (MTD)
Time frame: up to 21 days
The MTD is defined as the highest dose level at which less than 33% of the subjects experience a Dose Limiting Toxicity (DLT). DLT will be defined as grade 3 or 4 toxicity that is possibly, probably or definitely related to IT-hu14.18-IL2 graded according to CTCAE v. 5.0. A standard 3+3 design and descriptive statistics will primarily be generated to summarize the data.
Maximum Administered Dose (MAD)
Time frame: up to 21 days
The MAD is defined as the highest safely tolerated dose where less than 33% subjects experience a DLT but no higher dose level has been assessed. Descriptive statistics will primarily be generated to summarize the data.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing hu14.18-IL2, Radiation Therapy and Nivolumab in people with Melanoma, run by University of Wisconsin, Madison 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 17 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: stopped early, as of the sponsor's last update on 3 Jun 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Jun 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Adverse Events (time frame: up to 2 years). The study lists 3 primary outcomes in all. 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 3 Jun 2026.
