General information about the trial
|
|||
Main objective of the trial |
The first objective is to study the efficacy of autologous mRNA-transfected monocyte-derived DC in terms of progression free survival (PFS) in high-risk uveal melanoma patients.

Protection of trial subjects |
Adverse events were defined as any undesirable experience occurring to a subject during a clinical trial, whether or not considered related to the investigational treatment. All adverse events (AE) occurring during the study, whether or not definitely attributable to the immunization procedure, were recorded. Any CTC-grade 4 or other serious, life-threatening or fatal adverse event occurring within 28 days of receiving the last treatment must be reported within 24 hours to the study coordinator.
A serious adverse event is any untoward medical occurrence or effect that results in death;
- is life threatening (at the time of the event);
- requires hospitalisation or prolongation of existing inpatients’ hospitalisation;
- results in persistent or significant disability or incapacity;
- is a congenital anomaly or birth defect;
- is a new event of the trial likely to affect the safety of the subjects, such as an unexpected outcome of an adverse reaction, lack of efficacy of the treatment of a life threatening disease, major safety finding from a newly completed animal study, etc.
All SAEs will be reported to the accredited CMO that approved the protocol, according to the requirements of that CMO.
Follow-up of adverse events:
All adverse events will be followed until they have abated, or until a stable situation has been reached. Depending on the event, follow up may require additional tests or medical procedures as indicated, and/or referral to the general physician or a medical specialist.

Recruitment
|
|||||||||||
Recruitment details |
Uvea melanoma patients with a loss of chromosome 3 (monosomy 3; high-risk uvea melanoma), with an interval since local treatment <12 months, were included in this trial. | ||||||||||
Pre-assignment
|
|||||||||||
Screening details |
Additional inclusion criteria were UM expressing the melanoma-associated antigens gp100, age 18-75 years, and WHO performance status 0 or 1. Patients with distant metastases, serious concomitant disease or a history of a second malignancy we were excluded. HLA-A*02:01-positive patients were vaccinated, negative patients served as a control group. | ||||||||||

Dosage and administration details |
DC vaccination with DC loaded with KLH and transfected with mRNA encoding gp100 and tyrosinase will be administered three times on day 0, 14 and 28. DC will be simultaneously administered intradermally (i.d.) in the upper leg and intravenously (i.v.) 10 and 20 x 106 cells, respectively.
This regime is comparable to our previous trials in melanoma patients. The reason why we choose for this vaccination strategy is that it is shown in preclinical models that it may be beneficial to combine different routes of administration: depending on the localization of the tumor, intravenous or intradermal may be preferential for visceral and non-visceral metastases, respectively. Furthermore, to date our most promising clinical data are obtained in a group of stage IV melanoma patients vaccinated i.d. and i.v..
