Brief Summary:

This study involves testing of the medicine LTX-315 combined with a cancer vaccine (GV1001). This will be tested in patients that have had surgery with curative intent for malignant tumour.

GV1001 is a peptide vaccine in development to treat cancer. An adjuvant, is required to start the immune response in the body to have effect of GV-1001.

LTX-315, also a peptide, in development for cancer treatment. In this study, the investigators wish to find out whether LTX-315 can make GV1001 more effective at stimulating the immune system.


Condition or disease Intervention/treatment Phase
Carcinoma Drug: LTX-315 Phase 1

Detailed Description:

This clinical study has two main aims which are:

  • To measure the immunological effects of LTX-315 in combination with GV1001
  • Find out about the side effects of the combination of the two drugs This is an open label, single centre study assessing immunological effects and safety of LTX-315 given as an adjunct to GV1001. The LTX-315 dose will escalate while the GV1001 dose will be fixed.

LTX-315 and GV1001 will be given as intradermal injections on days 1, 8, 15, 22 and 36.

Investigational treatment: LTX-315 (0.10 mL) with escalating concentrations will be injected intradermally, followed, 1-2 hours later, by intradermal injection of 0.56 mg GV1001 (0.20 mL, 2.8 mg/mL) in the same site, in one arm.

DTH-test control: 0.10 mg GV1001 (0.10 mL) will be injected intradermally in the contralateral arm without LTX-315, as a DTH skin reactivity test control.

Actual Study Completion Date : January 2012

Arm Intervention/treatment
Experimental: LTX-315
The dose range of 0,25-2.0 mg/ML LTX-315 will be used. In combination with a fixed dose of GV-1001.
Drug: LTX-315
0.25-2.0 mg/ML, maximum 5 injections during 36 days.
Other Name: GV-1001




Primary Outcome Measures :
  1. Immunological effects of LTX-315 in combination with GV1001 as measured by DTH skin test reaction and T-cell function in peripheral blood. [ Time Frame: 5 injections, treatment period 36 days ]
    Patients will return to the site 24 to 48 hours after the LTX-315 and GV1001 injections for DTH assessment and in week 10 for an end of study assessment.


Secondary Outcome Measures :
  1. To evaluate the safety profile of LTX-315 in combination with GV1001 study [ Time Frame: 5 injections, treatment period 36 days ]
    Assessment of adverse events and abnormal laboratory values recorded during the
