Study summary

Approximately 36 DLT-evaluable subjects will be enrolled in this study. The locations of the study will be in the United States, Australia, Europe and Switzerland.

The goal of this study is to evaluate the safety of intrahepatic injection (directly into the liver) of talimogene laherparepvec in combination with intravenously administered atezolizumab in subjects with triple negative breast cancer and colorectal cancer with liver metastases.

Read the detailed description

The Screening period is 28 days prior to study enrollment. This study has 2 Cohorts. Cohort 1: Triple Negative Breast Cancer and Cohort 2: Colorectal Cancer. These cohorts will enroll in parallel. There will be a Safety Follow-up period and a Long Term Follow-up period.

Drug Administration: The participants will receive the study drugs in cycles. If the participants are found to be eligible to take part in this study, they will receive talimogene laherparepvec as an injection into the hepatic (liver) metastatic sites on Day 1 of each cycle along with receiving atezolizumab by intravenous infusion on Day 1 of each cycle. Each cycle is 21 days for 6 cycles. There is an option for an additional 6 cycles after the first 6 intra-hepatic cycles. After the first radiographic assessment at week 10, if all injectable liver lesions have been injected but the 4.0 mL maximum volume has not been used, injection of clinically assessed non-hepatic cutaneous, subcutaneous, and nodal tumor lesions with or without ultrasound guidance will be permitted. Liver lesions should be prioritized over cutaneous, subcutaneous and nodal lesions.

Treatment will continue until a participant experiences a DLT (Dose Limiting Toxicity) evaluated in the DLT period (which is 2 cycles from initial dose), has CR (Complete Response), has need for an alternative anticancer therapy or experiences a safety concern.

Study Visits: Cycle 1 to Cycle 12 - The participant will have a physical exam along with vital signs and ECOG (Eastern Cooperative Oncology Group) performance level assessment. Blood (about 2 Tablespoons) will be drawn for routine tests and to check the immune system. Adverse events and medications taken will be reviewed on each cycle.Biomarkers will be taken on cycles 1, 2, 3, 6, and safety FU. Tumor Markers (special lab tests associated with the cancer, such as particular proteins) will be completed will be take on cycles 1, 4, 7, 10, 13, every 3 cycles and SFU.

Central lab tests will be completed on cycles 1, 2, 3, and 6 and safety FU. Cycle 1 Archived (prior stored) tumor sample will be obtained. Also, a liver tumor biopsy will be completed at Cycles 1, 3 and 6.

Response Assessments will be completed at Screening and again at Cycles 4, 7, 10, 13 and every 3 cycles.

Throughout the trial a swab for Herpetic tumor will be obtained within 3 days of the event.

Cycle 1 to 12- The exposure to talimogene laherparepvec by the subject's healthcare provider and household member caregiver will be reviewed. Cycles 1, 3, 6-Liver tumor biopsy will be completed. Cycles 4, 7, 10, 13 and every 3 cycles -Response assessments will be completed by radiographic and clinical tumor assessment.

Length of Treatment:

A maximum for 12 cycles of talimogene laherparepvec are allowed during the study. The participant may continue taking the study drug for as long as the doctor thinks it is in their best interest. The participant will no longer be able to take the study drug if the disease gets worse, or if they are unable to follow study directions.

Safety Follow-up Visit:

Safety Follow-up visit will be performed about 30 days after the last dose of study treatment.

The participant will have a physical exam, have vital signs taken, assessment of ECOG status and have weight measured. Adverse events will be assessed as well as the concominant medications. Routine bloodwork and tumor markers will be taken.

Exposure to talimogene laherparepvec by the healthcare providers of the participant and/or close contacts will be assessed.

Long-Term Follow-up Visits: Participants will be followed for survival every 12 weeks from the date of the safety follow-up visit until approximately 24 months after the last subject is enrolled. Subsequent cancer treatments will be collected as part of the long-term follow-up survival assessment. This is an investigational study. The study doctor can explain how the study drugs are designed to work.

Terms in these criteria, in plain language(9)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Individual participant data

Plan to share: Yes — De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request

Supporting information: Study protocol, Statistical analysis plan, Informed consent form, Clinical study report

Time frame: Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

Access criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.

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 Mar 2018 to primary completion in May 2020, 26 months.

Results were first posted in Jun 2021, 1 year after primary completion.

Of 135 industry-sponsored phase 1 interventional studies under Triple Negative Breast Neoplasms, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 32 and three quarters within 70. This study's 26 months is below that.

Counting every sponsor, half of 208 studies reached it within 54 months; a quarter within 35 and three quarters within 80.

How these figures are worked out, and which studies are left out of them.

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 May 14, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
