About

To evaluate the safety and tolerability of intradermal injections of IMM-101 (Heat-killed Mycobacterium obuense) in melanoma cancer patients.

Full 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.

Enrollment: 19 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Exclusion criteria

• Pregnant or lactating females
• Major surgery within the 14 days preceding the screening visit

IMM-101

Experimental group

Description:

Patients received 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. Doses used were: 'Heat killed whole cell M. obuense (IMM-101) 0.1 mg', 'Heat killed whole cell M. obuense (IMM-101) 0.5 mg', or 'Heat killed whole cell M. obuense (IMM-101) 1.0 mg'

Treatment:

Biological: Heat-killed whole cell M.obuense (IMM-101) 0.5 mg

Biological: Heat killed whole cell M. obuense (IMM-101) 0.1 mg

Biological: Heat killed whole cell M.obuense (IMM-101) 1.0 mg
