rRp450-Phase I Trial in Liver Metastases and Primary Liver Tumors

June 15, 2024 updated by: Kenneth K. Tanabe, MD
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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 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.
  • Serum hematology and chemistry test results as outlined in the protocol.
  • Tumor volume occupies less than 50% of liver by volume as assessed by CT scan or MRI scan within 4 weeks of treatment
  • Negative pregnancy test (serum or urine) in premenopausal women
  • Prior exposure to HSV-1 as determined by blood test

Exclusion Criteria:

  • Clinical or pathological diagnosis of cirrhosis, hemachromatosis, or heptic fibrosis
  • Ascites or complete occlusion of main portal vein
  • Hepatitis C infection, chronic infection with hepatitis B, infection with HIV, or evidence of hepatic insufficiency
  • Inability to practice contraception with condoms as prescribed by the protocol
  • Active infection requiring treatment with systemic antibiotics or systemic anti-fungal agents
  • Being treated with immunosuppressive agents such as systemic corticosteroids or cyclosporine
  • Unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia, or need for antiarrythmic medication for which inability to take an oral preparation of regular medication for 48 hours would represent an unacceptable risk.
  • Known existing uncontrolled coagulopathy, hemorrhagic disorder, or inability to discontinue coumadin or plavix for 5 days prior to each treatment (except for prophylaxis against portacath-associated thrombosis, which does not require cessation of therapy).
  • History of seizures
  • Allergy to acyclovir or inability to receive contract for CT and MRI scans
  • Prior liver resection of greater than 2 anatomic segments as defined by Couinaud (subjects that have undergone prior liver wedge excisions or segmental resections are not excluded on this basis alone).
