Phase II FANG™ in Advanced Melanoma

May 21, 2018 updated by: Gradalis, Inc.

Phase II Trial of FANG™ Autologous Tumor Cell Vaccine in Advanced Melanoma

Preliminary studies with a variety of vaccines suggest target accessibility (potential immunogenicity) in a variety of solid tumors to immune directed approaches. In an effort to overcome limitations of immunostimulatory cancer vaccines, the investigators have designed a novel autologous vaccine to address inability to fully identify cancer associated antigens, antigen recognition by the immune system (i.e. antigen to immunogen), effector potency, and cancer-induced resistance. In an effort to overcome limitations of immunostimulatory cancer vaccines, the investigators designed a novel dual-modulatory autologous whole cell vaccine, Vigil™ (bi-shRNA furin and GMCSF Autologous Tumor Cell Vaccine), incorporating the rhGMCSF (recombinant human GMCSF) transgene and the bifunctional shRNAfurin (to block proprotein conversion to active TGFb1 and b2) to 1) address the inability to fully identify cancer associated antigens, 2) effect antigen recognition by the immune system (i.e. antigen to immunogen), 3) enhance effector potency, and 4) subvert endogenous cancer-induced immune resistance. The investigators have also completed the Phase I assessment of Vigil™ vaccine in 27 advanced solid tumor patients (1.0 x 10e7 or 2.5 x 10e7 cells/injection/month for a maximum of 12 vaccinations) who have not experienced any significant adverse effects following 131 vaccinations, including 4 patients with melanoma. Plasmid functionality, immune biomarker response, and preliminary evidence of anticancer activity have been observed. This is a Phase II study of intradermal autologous Vigil™ cancer vaccine (1.0 x 10e7 cells/injection; maximum of 12 vaccinations) in patients with stages IIIc and IV melanoma with biopsy accessible lesions to document blood and intratumoral immune responses and assess correlation with survival.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Enzyme-Linked ImmunoSorbent Spot (ELISPOT)
Time Frame: Baseline, End of Treatment (30 days after last dose) up to 12 months
To determine if subjects will have a positive (defined as >10 ELISPOTS from baseline) immune response to Vigil. Blood was collected to compare ELISPOT results from baseline until EOT (30 days after last dose).
Baseline, End of Treatment (30 days after last dose) up to 12 months

Secondary Outcome Measures
