Purpose

This study is to define the safety profile and to determine the Maximal tolerated dose regimen and preliminary efficacy of AbGn-107 administered every 14 days (Q2W regimen) or 28 days (Q4W regimen) in patients with chemo-refractory locally advanced, recurrent or metastatic gastric, colorectal, pancreatic or biliary cancer.

Detailed Description

      AbGn-107 is an antibody drug conjugate (ADC) which targets an antigen (AG7 antigen) present
      in gastric, colorectal, pancreatic cancer or biliary cancer. This study is a standard 3 + 3
      dose escalation design with cohort expansion. AbGn-107 will be administered every 14 days
      (Q2W regimen) or 28 days (Q4W regimen) in patients with chemo-refractory locally advanced,
      recurrent or metastatic gastric, colorectal, pancreatic adenocarcinoma or biliary cancer. The
      primary objectives of this study are to define the safety profile and to determine the
      maximum tolerated dose regimen of AbGn-107, and the secondary objectives are to evaluate the
      pharmacokinetic (PK) parameters, the immunogenicity, and preliminary efficacy of AbGn-107.

Eligibility Criteria

        Inclusion Criteria:

          1. Age ≥18 years. A patient may be of either sex and of any race/ethnicity.

          2. Histologically confirmed, chemo-refractory, locally advanced, recurrent or metastatic
             gastric (including GE junction), colorectal, or pancreatic adenocarcinoma or biliary
             cancer (including cholangiocarcinoma, gallbladder and ampullary carcinomas).

               1. Patient must not have curative options available (e.g. a single metastatic focus
                  in the liver in a patient with MCRC eligible for metastasectomy).

               2. Chemo-refractory is defined as:

                    -  Progression on or following, or intolerant of, at least one prior line of
                       standard systemic therapy for advanced or metastatic gastric or pancreatic
                       or biliary cancers.

                    -  Progression on or following, or intolerant of, at least two prior lines of
                       standard systemic therapy for advanced or metastatic colorectal cancers.

                    -  Patients who have progressed/recurred following neoadjuvant/adjuvant
                       chemotherapy for earlier stage disease, if completed within the previous 6
                       months, are eligible.

          3. Archived tissue must be available for all patients (both dose escalation and expansion
             cohorts). Dose Escalation Only-If tissue is not available, patients may still be
             considered eligible for enrollment, if all other eligibility criteria are confirmed
             and after discussion with and approval by the sponsor medical monitor. Cohort
             Expansion Only-Tissue must be to confirmed positive for expression of AG7 antigen
             during the Pre-Screening period, defined as proportional score ≥2, via slides or tumor
             block from either original diagnostic biopsy material or biopsy of relapsed
             disease,prior to enrollment.

          4. Measurable disease by RECIST 1.1 criteria

          5. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1.

             evidenced by:

               1. Absolute neutrophil count ≥1.5 x 10^9/L,

               2. Hemoglobin ≥9 g/dL,

         10. Life expectancy of at least 3 months.

             may be eligible, provided they have been definitively treated and are clinically
             stable, after discussion with sponsor. Treated or untreated leptomeningeal disease is
             not permitted.

          7. Known human immunodeficiency virus (HIV) infection or a known HIV-related malignancy.

             patient might be HIV positive.

          8. Known active hepatitis B or C. HBV and HCV tests are required prior to Day 1.

          9. Any clinically significant condition or situation, other than the condition being
             studied that, in the opinion of the investigator, would impair with their ability to
             receive or tolerate the planned treatment, or interfere with the study evaluations or
             optimal participation in the study.
