Study Details

Study Description

Brief Summary

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, Gradalis has designed a novel autologous vaccine to address inability to fully identify cancer associated antigens, antigen recognition by the immune system (i.e. antigen-->immunogen), effector potency, and cancer-induced resistance. In an effort to overcome limitations of immunostimulatory cancer vaccines, we designed a novel dual-modulatory autologous whole cell vaccine, Vigil™, incorporating the rhGMCSF 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, 3) enhance effector potency, and 4) subvert endogenous cancer-induced immune resistance. We have also completed the Phase I assessment of Vigil™ vaccine in 30 advanced solid tumor patients (1.0 x 10^{7 cells/injection/month for a maximum of 12 vaccinations) who have not experienced any significant adverse effects following 144 vaccinations, including 6 patients with colorectal carcinoma. Plasmid functionality, immune biomarker response, and preliminary evidence of anticancer activity have been observed. This is a two-part Phase II study of the Vigil™ autologous vaccine. Six patients will be enrolled into the Part 1 of the study to receive intradermal autologous Vigil™ cancer vaccine (1.0 x 10}7 cells/injection; maximum of 12 vaccinations). Part 2 of the study will be a randomized Phase II study of sandwich or adjuvant chemotherapy and intradermal autologous Vigil™ cancer vaccine (1.0 x 10^7 cells/injection; maximum of 12 vaccinations) versus sandwich or adjuvant chemotherapy and placebo in patients with colorectal carcinoma with either synchronous or metachronous liver metastases (CLM +/= pulmonary metastases) following resection +/= ablation with curative intent.Sandwich therapy indicates a combination of both pre-operative and postoperative chemotherapy as opposed to neo-adjuvant (all chemotherapy prior to surgery) or adjuvant (all chemotherapy following surgery) therapy. A minimum harvest aliquot to produce 4 monthly injections will be required for entry into the study. Patients in whom insufficient tissue (<4 doses) is collected or whose vaccine fails manufacturing release criteria will not receive vaccine.

Outcome Measures

Primary Outcome Measures

1. Immune Analysis in Tumor Biopsy and Blood (Part 1) [Up to 12 months]

   To evaluate and correlate Tumor Infiltrating Lymphocytes (TIL) in initial excised tumor and Enzyme-Linked ImmunoSorbent Spot (ELISPOT) responses to Vigil™ vaccine in blood of patients with CLM.

2. Percent of Patients Who Progressed After Treatment (Part 2) [24 months]

   Response rate will also be evaluated in this study using the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST) (unidimensional measurement) of the tumor lesions are used in the RECIST criteria.The response in patients with measurable disease will be reported using standard outcome measures for clinical trials: complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Any response to treatment (either PR or CR) requires two confirmatory staging at least 4 weeks apart. Patients will be evaluable for tumor response if measurable disease is present.

3. Percent of Patients Who Survived After Treatment (Part 2) [24 months]

   To determine and compare the overall survival rate in patients with CLM following resection +/- ablation with curative intent treated with sandwich or adjuvant chemotherapy and Vigil™ vaccine versus sandwich or adjuvant chemotherapy and placebo and compare with historical data.

Other Outcome Measures

1. Enzyme-Linked ImmunoSorbent Spot (ELISPOT) (Part 1) [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 30 days after last dose.

2. Number of Alive Subjects (Part 1) [24 Months]

   For Part 1, this was to determine the overall survival rate in patients with CLM following resection +/= ablation with curative intent treated with adjuvant chemotherapy and Vigil™ by following these patients up to 24 months.
