General information about the trial
|
|||
Main objective of the trial |
To evaluate whether TroVax® is active in the treatment of MPM. This will be assessed by measuring the cellular or humoral anti-5T4 immune responses following treatment with TroVax® given in combination with Pem/Cis.
|
||
Protection of trial subjects |
The trial involved the use of a genetically modified vaccine and this was reviewed and given ethical approval by the Gene Therapy Advisory Committee. Standard Operating procedures for the receipt, handling, storage, dispensing, transport, administration and disposal of the vaccine were put in place before the trial opened to protect patients and trial staff.
All patients were monitored for safety and serious adverse events throughout the trial.

Screening details |
Before any trial related procedures were undertaken to assess eligibility, the patient’s written informed consent was obtained. Eligible patients had locally advanced or metastatic, histologically or cytologically proven MPM and were fit to take trial treatment. 37 patients were screened, 3 were not eligibile criteria and 5 patients declined. | ||||||||||||||

Participants were given 9 intramuscular injections of TroVax®, starting two weeks before the commencement of chemotherapy, and continuing at regular intervals during and after chemotherapy. TroVax® is presented as lyophilised material. TroVax® was reconstituted by adding 1.2ml of water for injection (WFI). TroVax was given at a dose of 1 x 10^9 TCID 50/ml in 1ml by intramuscular injection into the deltoid muscle of the shoulder, given on Day 1 or 2 of weeks 1, 3, 6, 9, 12, 15, 18, 21, 24.

End point title |
Immune response to 5T4 (humoral or cellular) [1] | ||||||||||
End point description |
The outcome measure is the immune response to the 5T4 antigen. A success in this trial is defined as an increased response (at least a doubling in the 5T4 antibody or T-cell response) from that measured at baseline at any of the six follow-up time points.
The sample size was determined using Fleming’s single arm design. Using Fleming’s single-stage design, p1=0.40 and p2=0.64, setting alpha=0.05 (1-sided) and 80% power, 26 participants are required. If a doubling of 5T4 immune reponse is seen in at least 16 patients, then we can reject the null hypothesis that the vaccine does not elicit an immune response.
|
||||||||||
End point type |
Primary
|
||||||||||
End point timeframe |
The immune response is measured at six follow-up time points: after 2 injections; after 3 injections; after 4 injections; after 5 injections; after 9 injections; 10 weeks after the last injection.
|
||||||||||
Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: This Fleming's design requires a threshold number of events (n=16) to be observed. We observed 22 events. No further statistical analysis was required other than counting the number of events. |

06 Feb 2012 |
The was to notify the MHRA of an amendment to the Investigational Medicinal Product Dossier for Trovax for the SKOPOS trial. |
||
28 Aug 2012 |
This substantial amendment was to support an extension for the shelf life of TroVax drug product and matching placebo, stored at ≤ -15⁰c, from 60 months to 72 months. |
||
23 Jan 2013 |
This substantial amendment was to notify the MHRA of an amendment to the Investigators Brochure for TroVax, to Version 9.0. The PIS was amended to Version 3.0 to include additional information on treatment side effects.

||
01 Apr 2014 |
This substantial amendment was to notify the MHRA of an amendment to the Investigators Brochure for TroVax (to Version 10.0) and protocol (to Version 5.0).
The protocol was updated to include changes to the blood cell count values as part of the eligibility criteria and to clarify the CT schedule and RECIST assessment.
In addition, the amendment notified the MHRA of a recruitment extension until the end of October 2014. |
