CMV InfectionsPhase 1NCT02313857
Most Closely Human Leukocyte Antigen (HLA)-Matched CMV-specific T Lymphocytes (Viralym-C)
A Phase 1 study testing Viralym-C in people with CMV Infections, run by AlloVir at 2 sites in United States.
Trial summary
Patients enrolled on this study will have received a stem cell transplant. After a transplant, while the immune system grows back the patient is at risk for infection. Some viruses can stay in the body for life, and if the immune system is weakened (like after a transplant), they can cause life-threatening infections. Read more about this study

About this study
Official title: A Phase I Study Using Most Closely HLA-matched Cytomegalovirus-specific T Lymphocytes for the Treatment of Cytomegalovirus Infections Post-allogeneic Stem Cell Transplant(VIRALYM-C)
Patients enrolled on this study will have received a stem cell transplant. After a transplant, while the immune system grows back the patient is at risk for infection. Some viruses can stay in the body for life, and if the immune system is weakened (like after a transplant), they can cause life-threatening infections.
CMV can cause serious infections in patients with weak or suppressed immune systems. It usually affects the lungs, causing a very serious pneumonia, but it can also affect the gut, the liver and the eyes.

Investigators want to see if they can use a kind of white blood cell called T cells to treat CMV infections that occur after a transplant. Investigators have observed in other studies that treatment with specially trained T cells has been successful when the cells are made from the transplant donor. However as it takes 1-2 months to make the cells, that approach is not practical when a patient already has an infection.
Investigators have now generated CMV-specific T cells from the blood of healthy donors and created a bank of these cells. Investigators have previously successfully used frozen virus-specific T cell lines generated from healthy donors to treat virus infections after bone marrow transplant, and have now improved the production method and customized the bank of lines to specifically and exclusively target CMV.
In this study, investigators want to find out if the banked CMV-specific T cells derived from healthy donors are safe and can help to treat CMV infection.
The CMV-specific T cells (Viralym-C) are an investigational product not approved by the Food and Drug Administration (FDA).
Read the detailed description
To make CMV-specific T cells (Viralym-C cells), small pieces of protein called peptides that come from CMV were mixed with blood cells from healthy donors. These peptides train a kind of white blood cell called T cells to recognize and kill cells that are infected with CMV. These T cells were then grown in special growth factors in special flasks in the lab. Once we made sufficient numbers of cells, we tested them to make sure they recognized cells infected by CMV, and then we froze them.
When we think the subject needs them, Viralym-C cells will be thawed and injected into the intravenous line. To prevent an allergic reaction, prior to receiving Viralym-C cells the subject may be given diphenhydramine (Benadryl) and acetaminophen (Tylenol). The subject will remain in the clinic for at least one hour after the infusion. After the subject receives the cells, the transplant doctor will monitor the levels of CMV in the blood. We will also take blood to see how long the cells we gave the subject are lasting in the body.
Subjects will continue to be followed by their transplant doctors after the injection. The subject will either be seen in the clinic or they will be contacted by a research nurse to follow up for this study every week for 6 weeks, then at 3, 6 and 12 months. The subject may have other visits for their standard care. Subjects will also have regular blood tests done to follow their counts and the viral infection as part of their standard care.
To learn more about the way Viralym-C cells are working in the body, an extra 30-40 ml (6-8 teaspoons) of blood will be taken before the infusion and then at study follow-up visits at 1, 2, 3, 4 and 6 weeks, and 3 months after the infusion. Blood should come from the central intravenous line, and should not require extra needle sticks.
All participants on this study will be infused with the same number (dose) of cells. If Viralym-C infusion has helped the subjects infection or if they have had a treatment, for example with steroid drugs that might have destroyed the T cells the subject was given, then they are allowed to receive up to 4 additional infusions of the Viralym-C cells at the same initial dose level from 28 days after their initial infusion. Following infusions should be at least 14 days apart. After each Viralym-C cells infusion, subjects will be monitored as described above.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Viralym-CBiological
Follow-up Assessments: The timing of follow-up visits is based on the date of Viralym-C infusion. If a patient has multiple Viralym-C infusions the schedule resets again at the beginning so follow up relates to the last Viralym-C infusion.
Follow up will occur at 7 days, 14 days, 21 days, 28 days, 35 days, 42 days, 90 days, 180 days, and 365 days post enrollment.
| Study group | Role | What they receive |
|---|---|---|
| Viralym-C | Experimental | Partially HLA-matched Viralym-C cells will be thawed and given by intravenous injection. Patients will receive 2 x 10^7 partially HLA-matched Viralym-C/m2 as a single infusion.
If a patient has a partial response they are eligible to receive up to 4 additional doses at biweekly intervals. These doses would come from the original infused line if sufficient vials were available but may come from another line if there are insufficient cells in the original line.

What is being measured
The primary outcome is the main question the study is designed to answer.
Assessment of patients with adverse events after Viralym-C infusion
To determine if administration of banked CMV-specific T cells (Viralym-C) derived from healthy donors are safe in patients with CMV infection after allogeneic stem cell transplant.
Measured: 42 days
Secondary outcomes (2)
Assessment of CMV load response to the Viralym-C infusion
Viral load over time within a patient will be visualized to reveal the temporal patterns of immune response. Plots of smooth curves will be generated for each patient to graphically illustrate the pattern and duration of T-cell changes.
Measured: 1 year
Reconstitution of antiviral immunity after Viralym-C infusion
Reconstitution of antiviral immunity over time within a patient will be visualized to reveal the temporal patterns of immune response. Plots of smooth curves will be generated for each patient to graphically illustrate the pattern and duration of T-cell changes.
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Viralym-C in people with CMV Infections, run by AlloVir at 2 sites 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 12 inclusion and 6 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: finished, as of the sponsor's last update on 26 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Assessment of patients with adverse events after Viralym-C infusion (time frame: 42 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02313857, which also lists 2 linked publications.
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 26 Dec 2018.
