About this study
Official title: A Phase II Study of Combining Talimogene Laherparepvec (T-VEC) (NSC-785349) and MK-3475 (Pembrolizumab) (NSC-776864) in Patients With Advanced Melanoma Who Have Progressed on Anti-PD1/L1 Based Therapy
This phase II trial studies how well talimogene laherparepvec and pembrolizumab work in treating patients with stage III-IV melanoma. Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop tumor cells from growing. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving talimogene laherparepvec and pembrolizumab may work better in treating patients with melanoma by shrinking the tumor.
Read the detailed description
PRIMARY OBJECTIVE:
- To evaluate the objective response rate (confirmed complete and partial responses) of treatment with talimogene laherparepvec (T-VEC) in combination with pembrolizumab (MK-3475) following progression on prior anti-PD-1 or anti-PD-L1 therapy alone or in combination with other agents different from talimogene laherparepvec (T-VEC).
SECONDARY OBJECTIVES:
- To estimate the durable response rate. II. To estimate the objective response rate (ORR) defined as confirmed and unconfirmed, complete and partial responses in the injected lesions.
III. To estimate the ORR in the non-visceral, non-injected lesions. IV. To estimate the ORR in the visceral lesions (Cohort A). V. To estimate the median progression-free survival (PFS). VI. To estimate the median overall survival (OS). VII. To evaluate the toxicity of the regimen.
TRANSLATIONAL OBJECTIVES:
- To evaluate whether adding talimogene laherparepvec (T-VEC) to PD1 blockade can increase T-cell infiltration into tumors and whether change in T-cell infiltration is associated with response.
II. To evaluate whether adding talimogene laherparepvec (T-VEC) to PD1 blockade can increase T-cell receptor (TCR) clonality in tumors and in peripheral blood and whether increased TCR clonality is associated with response.
III. To evaluate whether intra-tumoral injection of talimogene laherparepvec (T-VEC) can improve the tumor immune microenvironment.
IV. To evaluate whether tumor mutational load, mutations in the IFN pathway, and circulating tumor deoxyribonucleic acid (DNA) profile are is associated with response to talimogene laherparepvec (T-VEC) plus pembrolizumab (MK-3475) therapy in the anti-PD1/L1 therapy refractory melanoma patients.
OUTLINE:
Patients receive talimogene laherparepvec intralesionally (IL) and pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 36 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6 months for up to 1 year and then annually for a total of 5 years.

What is being measured
The primary outcome is the main question the study is designed to answer.
Objective Response Rate (ORR)
Number of participants with a complete response, defined as the disappearance of all target and non-target lesions, or partial response, defined as a greater than or equal to 30% decrease under baseline of the sum of appropriate diameters of all target measurable legions. ORR is measured using RECIST 1.1 guidelines.
Measured: Up to 5 years post registration or until death
Secondary outcomes (7)
Durable Response Rate
Number of participants with complete or partial response per RECIST 1.1 with no evidence of disease progression for at least 180 days from the initial documentation of CR/PR.
Measured: Up to 5 years post registration or until death
Objective Response Rate (ORR) in Injected Lesions
Number of participants with confirmed and unconfirmed complete and partial responses in injected lesions. A confirmed complete response (CR) is defined as 2 or more consecutive objective statuses of CR a minimum of 4 weeks apart, a confirmed partial response is defined as 2 or more consecutive objective statuses of PR or better a minimum of 4 weeks apart but no qualifying as a CR. A unconfirmed CR is defined as 1 objective status of CR but not qualifying as a CR or PR, a unconfirmed PR is defined as 1 objective status of PR but not qualifying as CR, PR, or unconfirmed CR. ORR is measured per RECIST 1.1 guidelines.
Measured: Up to 5 years post registration or until death
Objective Response Rate (ORR) in Non-Visceral, Non-Injected Lesions
Number of participants with confirmed and unconfirmed complete and partial responses in non-visceral, non-injected lesions. A confirmed complete response (CR) is defined as 2 or more consecutive objective statuses of CR a minimum of 4 weeks apart, a confirmed partial response is defined as 2 or more consecutive objective statuses of PR or better a minimum of 4 weeks apart but no qualifying as a CR. A unconfirmed CR is defined as 1 objective status of CR but not qualifying as a CR or PR, a unconfirmed PR is defined as 1 objective status of PR but not qualifying as CR, PR, or unconfirmed CR. ORR is measured per RECIST 1.1 guidelines.
Measured: Up to 5 years post registration or until death
Objective Response Rate (ORR) in Visceral Lesions (Cohort A)
Number of participants with confirmed and unconfirmed complete and partial responses in visceral lesions. A confirmed complete response (CR) is defined as 2 or more consecutive objective statuses of CR a minimum of 4 weeks apart, a confirmed partial response is defined as 2 or more consecutive objective statuses of PR or better a minimum of 4 weeks apart but no qualifying as a CR. A unconfirmed CR is defined as 1 objective status of CR but not qualifying as a CR or PR, a unconfirmed PR is defined as 1 objective status of PR but not qualifying as CR, PR, or unconfirmed CR. ORR is measured per RECIST 1.1 guidelines.
Measured: Up to 5 years post registration or until death
Progression-Free Survival (PFS)
Time from date of first registration to date of first documentation of progression or death due to any cause. Patients last known to be alive without report of progression are censored at date of last contact.

Unequivocal progression of non-measurable disease in the opinion of the treating physician (an explanation must be provided). Appearance of any new lesion/site. Death due to disease without prior documentation of progression and without symptomatic deterioration.
Measured: Up to 5 years post registration or until death
Overall Survival (OS)
Time from date of registration to date of death due to any cause. Participants last known to be alive are censored at date of last contact.
Measured: Up to 5 years post registration or until death

Is this clinical trial currently recruiting?

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 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 27 Aug 2024). 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?
Objective Response Rate (ORR) (time frame: Up to 5 years post registration or until death). 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 20 May 2026.
