Spots Global Cancer Trial Database for In Situ Immunomodulation With CDX-301, Radiation Therapy, CDX-1140 and Poly-ICLC in Patients w/ Unresectable and Metastatic Solid Tumors

Study Description

Brief Summary: This phase I trial evaluates the side effects of radio-immunotherapy (CDX-301, radiotherapy, CDX-1140 and Poly-ICLC) in treating patients with unresectable and measurable metastatic melanoma, cutaneous squamous cell carcinoma (SCC), Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or HER2/neu(-) breast cancer. CDX-301 may induce cross-presenting dendritic cells, master regulators in the immune system. Radiation therapy uses high energy to kill tumor cells and release antigens that may be picked up, processed and presented by cross-presenting dendritic cells. CDX-1140 and Poly-ICLC may activate tumor antigen-loaded,cross-presenting dendritic cells, and generate tumor-specific T lymphocytes, a type of immune cells, that can search out and attack cancers. Giving immune modulators and radiation therapy may stimulate tumor cell death and activate the immune system.

Detailed Description: PRIMARY OBJECTIVE: I. To evaluate the safety profile of in situ immunomodulation with recombinant Flt3 ligand (CDX-301), radiotherapy, agonistic anti-CD40 monoclonal antibody CDX-1140, and Poly-ICLC in unresectable and metastatic melanoma, cutaneous squamous cell carcinoma, Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or breast cancer patients with injectable palpable disease by determining the maximum tolerated dose (MTD) of CDX-1140 that has an acceptable adverse event profile. SECONDARY OBJECTIVE: I. To evaluate the immune signatures in the tumor microenvironment before and after in situ immunomodulation with CDX-301, radiotherapy, CDX-1140, and Poly-ICLC. EXPLORATORY OBJECTIVES: I. To record the overall response rate (ORR) (complete response \[CR\] and partial response \[PR\]) of injected as well as distant uninjected metastatic lesions in metastatic melanoma, cutaneous SCC, Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or breast cancer patients with injectable palpable disease treated with in situ immunomodulation with CDX-301, radiotherapy, CDX-1140, and Poly-ICLC by immune-related Response Evaluation Criteria In Solid Tumors (irRECIST) response assessment, and compare intratumoral alone versus (vs.) intratumoral + intravenous administration of CDX-1140. II. To record the overall survival (OS) and progression free survival (PFS) in unresectable and metastatic melanoma, cutaneous SCC, Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or breast cancer patients with injectable palpable disease treated with in situ immunomodulation with CDX-301, radiotherapy, CDX-1140, and Poly-ICLC, and compare intratumoral alone vs. intratumoral + intravenous administration of CDX-1140. III. Examine changes in the levels of T-cell subsets/myeloid derived suppressor cells (MDSC)/cytokines in peripheral blood (PB) of unresectable and metastatic melanoma, cutaneous SCC, Merkel cell carcinoma, high-grade bone and soft tissue sarcoma or breast cancer patients with injectable palpable disease treated with in situ immunomodulation with CDX-301, radiotherapy, CDX-1140, and Poly-ICLC. OUTLINE:Cohort A will evaluate safety of intratumoral administration of CDX-1140 in combination with CDX-301, radiotherapy and Poly-ICLC. Once cohort A is finished, patients will be enrolled to cohort B to evaluate safety of intratumoral + intravenous administration of CDX-1140 in combination with CDX-301, radiotherapy and Poly-ICLC. COHORT A: Patients receive recombinant Flt3 ligand intratumorally (IT) on days 1-5 and agonistic anti-CD40 monoclonal antibody CDX-1140 IT with Poly-ICLC IT on day 9 or 10. Patients also undergo radiation therapy on day 8 or 9. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity. COHORT B: Patients receive recombinant Flt3 ligand IT on days 1-5 and agonistic anti-CD40 monoclonal antibody CDX-1140 IT and intravenously (IV) over 90 minutes with Poly-ICLC IT on day 9 or 10. Patients also undergo radiation therapy on day 8 or 9. Treatment repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and then every 3-6 months for 2 years.
