Radio-immunotherapy (CDX-301, Radiotherapy, CDX-1140 and Poly-ICLC) for the Treatment of Unresectable or Metastatic Breast Cancer Patients

NCT04616248

Description:

This phase I trial evaluates the side effects of radio-immunotherapy (CDX-301, radiotherapy, CDX-1140 and Poly-ICLC) in treating patients with breast cancer that cannot be removed by surgery (unresectable) and has spread to other places in the body (metastatic). 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 breast cancer patients with injectable palpable disease.

      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 distant uninjected metastatic lesions in metastatic 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 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 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 6
      months for 2 years.
