Melanoma
Conditions
Brief summary
To evaluate the safety and tolerability of intradermal injections of IMM-101 (Heat-killed Mycobacterium obuense) in melanoma cancer patients.
Detailed description
The proposed study is a first-in-man, placebo-controlled, dose escalation trial to evaluate the safety and tolerability of three different doses of IMM-101 administered intradermally to melanoma patients. Additionally, the study aims to characterize local responses to this vaccine in order to delineate unexpected / unacceptable local reactions from those indicative of appropriate immunological response in this patient group.
Interventions
Each patient will receive an intradermal placebo injection of borate buffered saline solution (day -3) to provide an intra patient placebo control. Patients who were willing and able to proceed with the study will receive an intradermal injection of a single dose level of IMM 101 on three subsequent occasions. Doses of IMM 101 were administered over a 4 week period on days 0, 14 and 28. Dose levels to be administered are 0.1 mg, 0.5 mg and 1.0 mg.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events as a Measure of Safety and Tolerability | 56 days | Safety and tolerability were measured with respect to: 1. Safety measurements 2. Local tolerability at the site of intradermal injection 3. Incidence of adverse events. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Administration Site Reactions | Day -3 to Day 56 | Local skin reactions are viewed as a normal and predicted reaction to exposure to a preparation of mycobacterial antigens. All patients experienced administration site reactions and all reactions were examined and characterised. However only those reported as adverse events are presented here. |

Outcome results
Number of Participants With Adverse Events as a Measure of Safety and Tolerability
Safety and tolerability were measured with respect to: 1. Safety measurements 2. Local tolerability at the site of intradermal injection 3. Incidence of adverse events.
Time frame: 56 days
Population: All analyses were based on the safety population, which comprised of all patients who received at least one dose of IMP. Safety measurements and nature and incidence of adverse events were reported for the Safety population
