Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult

- 18 years of age or more and able to understand and sign a written informed consent form
- Histologically confirmed diagnosis of cancer with liver metastases, or histologically confirmed primary liver cancer (e.g. hepatocellular carcinoma, cholangiocarcinoma, or gallbladder carcinoma). Subjects may have extrahepatic spread of malignancy, except they may not have brain metastases. Subjects with a history of more than one invasive malignancy remain eligible for this study, but in these instances, a liver biopsy is required to document the histology of the liver tumor. An exception to this criterion is made for basal cell carcinoma.
- Subjects must have primary or metastatic liver malignancies which are surgically unresectable, and exhausted all standard therapeutic options
- Patients with hepatocellular carcinoma must have received sorafenib as one of the standard treatment options prior to being enrolled into the study
- No liver surgery (including radiofrequency ablation), chemotherapy (including bevacizumab), immunotherapy, or liver radiotherapy within 4 weeks of enrollment.
- ECOG performance status 0, 1 or 2 and life expectancy of greater than 12 weeks based on the investigator's clinical judgment.

About this study
The purpose of this research study is to determine the safety of rRp450 and the highest dose of this agent that can be given to people safely. We are also looking to see how well the body tolerates the study agent, how the agent is absorbed by the liver cancers, how quickly the agent is eliminated from the body, and what kind of anti-cancer effect it may have. rRp450 is a type of gene therapy and a form of the Herpes simplex virus 1 (or HSV). HSV is a virus that usually causes cold sores of the mouth. In extremely rare circumstances, this virus can cause severe infections, such as an infection of the brain. rRp450 was developed from an HSV and specially altered to target and kill cancer cells.
Read the detailed description
- Since we are looking for the highest dose of the study agent that can be administered safely without severe or unmanageable side effects in participants that have liver tumors, not everyone who participates in this research study will receive the same dose of the study drug. The dose the participant receives will depend on the number of participants who have been enrolled in the study before and how well they tolerated their doses.
- Depending upon when the participant enrolls in this study, they will either receive a single injection of rRp450, or up to 4 weekly injections of rRp450. Participants in both groups will be monitored after the rRp450 injection in the hospital and in the clinic. As of July, 2013, because the first phase of the study has been completed, all participants from here forward will receive 4 weekly injections of rRp450
- For the rRp450 injection, we will insert a small tube into the artery that supplies blood to the liver. rRp450 will be injected into this tube so it goes directly to the liver. Another tube is inserted into the blood vessel that drains blood from the liver. We will use this tube to take blood samples to monitor how the body absorbs and breaks down rRp450.
- After the rRp450 injection, participants will be monitored closely for any side effects. Vital signs will be closely monitored before, during and after rRp450 injection. After the rRp450 injection, the tubes are removed.
- The following tests and procedures are done before the rRp450 injection: determination of overall health condition, performance status evaluation, review of current medications and any side effects, physical exam and vital signs.
- The following tests and procedures will be done during the injection of rRp450: vital signs, review of any side effects, research blood samples taken from a vein in your arm, and research blood samples taken from your liver vein.
- The following tests and procedures will be done after rRp450 injection: 1 Hour after; blood tests: 6 and 12 hours after; blood tests, vital signs, routine blood tests, samples of saliva and swabs of the skin of the penis or vaginal secretions (hour 12 only): 24 hours after, Between days 4 to 7 and Between days 10 to 14; review of current medications and side effects, physical exam, vital signs, routine blood tests, swab samples of saliva, blood test to see if the body has produced antibodies against HSV-1 (only on day 4 to 7 and only for participants enrolled in the single injection group).
- Liver and tumor biopsies will be performed about 6 days after the rRp450 injection.
- Participants will be asked to return to the clinic 2 weeks, 4 weeks, and every 3 months thereafter after their last injection of study medication.

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 10 inclusion and 11 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 18 Jun 2024. 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?
The study was stopped early (reason given: Inadequate funding). Results are not available in the source record.
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?
Evaluate the safety and tolerability of rRp450 administered into the hepatic artery as a single dose. (time frame: 3 years). The study lists 4 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 18 Jun 2024; AzTrials last refreshed its copy on 7 Nov 2026.
