General information about the trial
|
|||
Main objective of the trial |
Efficacy of L19IL2/L19TNF-treated lesions measured as rate of patients with complete response (CR) at week 12 (day 85).
|
||
Protection of trial subjects |
Safety of the patients was carefully evaluated during all the period in which the patient was in the study.
During the active treatment phase, regular laboratory analysis of the common clinical parameters were performed, as also physical examination and vital signs monitoring.

Recruitment details |
Overall, 22 patients were enrolled from 05.12.2012 to 23.05.2014: 13 at the Milan site and 9 at the Siena site. | ||||||||||||||||
Pre-assignment

Screening details |
After obtaining patient informed consent, screening evaluations and procedures had to be performed within 14 days prior to the start of therapy. At the screening visit, a full evaluation of the status of patient was performed. Based on the information obtained from the assessments, the patient's eligibility was decided upon. | ||||||||||||||||

Arm description |
Patients were treated with a combination of 10 Mio IU of L19IL2 and 312 μg of L19TNF to be administered in an approximate volume of 4.2 ml as a single or multiple intratumoral injection once every week for up to 4 weeks. L19IL2 was dosed at 10 Mio IU per administration, the amount of L19TNF per administration was 312 μg. However, the dose could be adjusted between 78 and 312 μg per administration according to size and number of lesions and at the investigator's discretion. The total daily dose was distributed between all injectable soft-tissue metastases. | ||||||||||||||||

Statistical analysis description |
A two-sided exact binomial statistical test was applied for the rate of patients with CR, OR, and DC of the L19IL2/L19TNF-treated lesions and all lesions for all the available tumor assessments. The
hypothesized value for the null hypothesis was 50%. The duration of OR and DC was calculated using Kaplan Meier estimator for the treated lesions and for all the lesions.
