Brief Summary

This phase I/II trial studies the side effects and how well fluorescence image guided surgery followed by intraoperative photodynamic therapy for improving local tumor control in patients with colorectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or that has come back after a period of improvement (recurrent). Fluorescence image guided surgery uses a drug named aminolevulinic acid hydrochloride. Aminolevulinic acid hydrochloride is a photosensitizing agent, meaning that is activated by light and, is converted to another drug in cancer cells more than in normal cells. The converted drug emits fluorescence red light when activated with low power blue light. It is used to assist the surgeon to see cancer cells and small cancerous tissue that may have been missed during routine surgery. In addition to emitting fluorescence light, the converted drug in the cancer cells and tissue can be activated with red laser light to kill cancer cells. This procedure is called photodynamic therapy (PDT). Performing fluorescence image guided surgery followed by intraoperative photodynamic therapy after the surgical removal of the colorectal tumor before the surgical site will be closed may be effective and improve outcomes in patients with locally advanced or recurrent colorectal cancer.

Outcome Measures

Primary Outcomes (4)

  • Accuracy of the fluorescence imaging (Phase I)

    Will be determined by histopathology by examining the number of true positive fluorescence cases out of the total positive fluorescence biopsies collected in the study. This will be determined by reviewing the pathology reports. The proportion of surgical cases exhibiting a positive fluorescence signal by utilizing a simple proportion along with a 95% confidence interval.

    Up to 3 years

  • Incidence of adverse events (Phase I)

    Will be measured by recording Gleolan administration and intraoperative photodynamic therapy (PDT) treatment related adverse events that are ≥ grade 3 with attribution of 'probable', or 'definite', according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0, that do not resolve within 7 days.

    Up to 30 days post-therapy

  • Evidence of disease (Phase II)

    Will be assessed by standard-of-care computed tomography (CT) and/or magnetic resonance imaging (MRI). The recurrence proportion and exact 95% confidence interval will be calculated.

    At 12 weeks post treatment

  • Changes in carcinoembryonic antigen (CEA) and circulating tumor deoxyribonucleic acid (ctDNA) (Phase II)

    Will be evaluated by collecting peripheral blood samples. The mean and a 95% confidence interval will be calculated around the mean change from baseline.

    Within 4 weeks prior to surgical/PDT intervention and 4-6 weeks after treatment

Secondary Outcomes (6)

  • Changes in CEA and ctDNA (Phase I)

    At 4 weeks prior to surgical/PDT intervention and 4-6 weeks after treatment

  • Rate of recurrence (Phase I)

    At approximately 3 months post treatment, and during long term followup will be part (every 3 to 6 months up to 3 years)

  • Rate of local recurrence (Phase II)

    Within 3 years post treatment during standard of care follow ups

  • Disease free survival (Phase II)

    Up to 3 years after treatment

  • Correlation between disease free survival and changes in levels of CEA (Phase II)

    At 4-6 weeks after treatment

  • +1 more secondary outcomes

Study Arms (1)

Treatment (aminolevulinic, fluorescence-guided surgery, PDT)

EXPERIMENTAL

Patients receive aminolevulinic acid PO 2 to 4 hours prior to SOC surgery. Patients then undergo image-guided fluorescence 5-10 minutes post surgery, and intraoperative PDT 15-45 minutes post surgery. Patients also undergo CT or MRI during screening and on follow up. Patients also undergo blood sample collection throughout the trial.
