About this study
Official title: A Phase I/IIa Dose Escalation Study in Asia of Repeated Administration of "CYT107" (Glyco-r-hIL-7) Added on Treatment in Genotype 1 HCV Infected Patients Resistant to Pegylated Interferon-alpha and Ribavirin
This study is designed to evaluate the safety of biological active dose of a new experimental drug, IL-7, in combination with standard bi-therapy in Asiatic patients with Hepatitis C chronic infection identified as non responders to the standard bi-therapy alone.
Read the detailed description
This is a Phase I/IIa inter-patient dose-escalation study assessing weekly doses of Interleukin-7 (CYT107) in Asiatic adult patients infected by virus of genotype 1 of Hepatitis C and resistant to standard treatment with Peg-Interferon and Ribavirin (bi-therapy).
The dose escalation is aimed at establishing the safety of a biologically active doses of CYT107 added to the combination therapy of pegylated interferon-alpha and ribavirin. At each dose level, study patients will receive one subcutaneous administration of CYT107 per week for a total of 4.
Groups of 3 to 6 patients will be entered at each dose level of CYT107. Three dose levels are planned.
Eligible patients initially receive bi-therapy for 6-10 weeks. Thereafter, CYT107 is added for a cycle of four weekly injections at a defined dose level while standard bi-therapy continues for 9 weeks after CYT107 treatment discontinuation. The patients are then followed on a regular basis until reaching 48 weeks after the CYT107 treatment. The duration of study is approximatively 60 weeks with 20-25 weeks of bi-therapy.
Participants will have 1 overnight hospitalization and 15 clinic visit on a period of 60 weeks.
During the visits the following may be done:
- medical history, physical examination, blood tests
- electrocardiograms (ECG)
- chest X-Ray
- liver/spleen imaging
- urine tests
- Conditions
- Hepatitis C
- Being tested

The dose escalation is aimed at establishing the safety of a biologically active doses of CYT107 added to the combination therapy of pegylated interferon-alpha and ribavirin. At each dose level, study patients will receive one subcutaneous administration of CYT107 per week for a total of 4.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Interleukin-7 in people with Hepatitis C, run by Cytheris SA at 4 sites in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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: status not confirmed, as of the sponsor's last update on 18 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Taiwan. 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 combined 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.
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?
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?
safety of biologically active doses of CYT107 added to a combination therapy by pegylated interferon-alpha and ribavirin in Asian patients with a chronic infection by a genotype 1 HCV not responding to this combination therapy (time frame: 12 weeks after start of CYT107). 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 Oct 2012.
