Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cell immunotherapy to elicit HCV-specific immune responses in patients who have previously failed interferon-based therapy.
The dose will vary from 10,000 to 100 million HCV antigen positive cells, administered by the intradermal route. Patients will receive these cell numbers in 1, 2 or 3 doses with one week between doses.

Comparator / control treatment
Patients will represent their own control as the viral load and immunological parameters will be studied before and after intervention.

Uncontrolled

Outcomes
Primary outcome [1] 257610 0
Safety.
Clinical examination.
Haematology-full blood examination
Clinical chemistry-full study, including liver function tests (LFT).
HCV viral load.
Timepoint [1] 257610 0
Weekly during intervention and weekly for 6 weeks after intervention.
Secondary outcome [1] 262881 0
Induction of HCV-specific cell mediated immunity.
This will be assessed by Enzyme-linked immunosorbent spot (ELIspot) examination of peripheral blood mononuclear cells (PBMC) using HCV peptide pools as the stimulating antigen.
The viral load will be assessed by reverse transcriptase-polymerase chain reaction (RT-PCR).
Timepoint [1] 262881 0
Weekly during intervention and weekly for 6 weeks after intervention.

Study design
Purpose of the study
Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients will be enrolled by a clinician who normally provides care. The trial will be discussed during a normal appointment in the liver clinic, the patient provided with a patient information and consent form (PICF) which he/she is encouraged to read and discuss with family/friends and/or their general practitioner. The consent form will be signed in the clinic in the presence of their liver specialist.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be enrolled essentially as they appear in the clinic.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Single group
Other design features
The trial will be a dose escalation trial.

Summary
Brief summary
The study is designed to examine the hypothesis that increasing the level of specific immunity to the proteins of hepatitis C virus will result in a reduction in the viral load and/or clearance of the virus.
