Brief Summary:

Our study evaluates the use of Laser-Assisted Immunotherapy (LIT) plus placebo and LIT plus low-dose cyclophosphamide versus that of Standard of Care in patients presenting with Stage IIIA, IIIB or IV breast cancer.

One-third of enrolled patients will receive LIT plus placebo, one-third will receive LIT plus low-dose cyclophosphamide, and one-third will be assigned to a control group that receives Standard of Care.


Condition or disease Intervention/treatment Phase
Breast Cancer Stage IIIA Breast Cancer, Stage IIIB Breast Cancer Stage IV Drug: 1% Glycated Chitosan Device: Photothermal Laser Drug: Placebo Drug: Cyclophosphamide Drug: Standard of Care Phase 3

Detailed Description:

Laser-Assisted Immunotherapy (LIT) is intended to a systemic anti-tumor immune response by priming a tumor with laser energy to liberate an array of tumor antigens from whole cells, immediately followed by administration of the immune stimulant Glycated Chitosan (GC), which is designed to activate antigen presenting cells and facilitate the uptake of tumor antigens. In turn, the antigen presenting cells activate the patient's immune system, resulting in an immune response towards the remaining tumor(s).

In this study it is investigated if the addition of low-dose cyclophosphamide increases the anti-tumor immune response of LIT, as well as comparing the effect of LIT plus Placebo or LIT plus low-dose cyclophosphamide to a control arm of patients receiving Standard of Care therapy.

Arm Intervention/treatment
Experimental: Arm 1: LIT and Placebo
Patients receive laser-assisted immunotherapy along with Placebo cyclophosphamide tablets. Patients' laser-assisted immunotherapy treatment will be based on the number and size of laser-accessible solid tumors available at the time of treatment. In and around each photothermal laser-treated site will be injected 1 mL of 1% Glycated Chitosan (GC) Injection, with a total of up to 4 sites being treated per patient. The maximum dose of GC Injection that a patient can receive in 1 visit is 4 mL.
Drug: 1% Glycated Chitosan
Other Name: GC

Device: Photothermal Laser
Drug: Placebo
Experimental: Arm 2: LIT and low-dose Cyclophosphamide
Patients will receive laser-assisted immunotherapy and low-dose cyclophosphamide (300 mg, administered orally once per week between treatment weeks 0-11 in each treatment cycle). Patients' laser-assisted immunotherapy treatment will be based on the number and size of laser-accessible solid tumors available at the time of treatment. In and around each photothermal laser-treated site will be injected 1 mL of 1% Glycated Chitosan (GC) Injection, with a total of up to 4 sites being treated per patient. The maximum dose of GC Injection that a patient can receive in 1 visit is 4 mL.
Drug: 1% Glycated Chitosan
Other Name: GC

Device: Photothermal Laser
Drug: Cyclophosphamide
Active Comparator: Arm 3: Control Arm
Patients will receive the standard of care.
Drug: Standard of Care



Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: Assessed as week 52 ]
    Overall response rate (ORR) (defined as the percent of patients within each treatment group that achieved complete or partial response, according to irRC, at the end of week 52) comparison between each LIT group and control group.


Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: Week 0 through Week 52 of study period ]
    Overall survival (OS): There will be an OS comparison between the treatment arms 1 and 2 vs. control arm at the end of the 52 week trial.

  2. Relative change in overall tumor burden [ Time Frame: Week 0 through Week 52 of study period ]
    Patients demonstrate a 20% improved relative overall change of total tumor burden compared to the control group at the end of the 52 week trial period.

  3. Health Related Quality of Life (HRQOL) [ Time Frame: Week 0 through Week 52 of study period ]
    To assess and compare the HRQOL of those that receive laser-assisted immunotherapy vs Control. HRQOL refere to a multidimensional assessment that includes at least the physical, emotional (or psychological) and social domain, and may also include cognitive functioning, sexuality, and spirituality. The Assessment will be QOL Scale/Breast Cancer designed by NATIONAL MEDICAL CENTER AND BECKMAN RESEARCH INSTITUTE.

  3. Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
  4. Patient has adequate organ function, confirmed by the following laboratory values obtained ≥14 days prior to the first treatment:

    • Bone Marrow Function:

      1. Absolute neutrophil count (ANC) ≥1.5 × 103/mm3
      2. Platelets >75 × 103/mm3
      3. Hemoglobin ≥9 g/dL
