A Study of AbGn-107 in Patients With Gastric, Colorectal, or Pancreatic Cancer
a study on Pancreatic Cancer
This study is to define the safety profile and to determine the maximum tolerated dose (MTD) and preliminary efficacy of AbGn-107 administered every 28 days (4 weeks) in patients with chemo-refractory locally advanced, recurrent or metastatic gastric, colorectal or pancreatic adenocarcinoma.
A Phase I Dose Escalation Study, With Cohort Expansion, to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of AbGn-107 Therapy in Patients With Chemo-refractory Locally Advanced, Recurrent, or Metastatic Gastric, Colorectal, or Pancreatic Cancer
AbGn-107 is an antibody drug conjugate (ADC) which targets an antigen (AG7 antigen) present in gastric, colorectal, and pancreatic cancer. This study is a standard 3 + 3 dose escalation design with cohort expansion. AbGn-107 will be administered every 28 days in patients with chemo-refractory locally advanced, recurrent or metastatic gastric, colorectal or pancreatic adenocarcinoma. The primary objectives of this study are to define the safety profile and to determine the maximum tolerated dose (MTD), and the secondary objectives are to evaluate the pharmacokinetic (PK) parameters, the immunogenicity, and preliminary efficacy.

Open to people ages 18 years and up
- Age ≥18 years. A patient may be of either sex and of any race/ethnicity.
- Histologically confirmed, chemo-refractory, locally advanced, recurrent or metastatic gastric (including GE junction), colorectal, or pancreatic adenocarcinoma.
- Patient must not have curative options available (e.g. a single metastatic focus in the liver in a patient with MCRC eligible for metastasectomy).
- 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 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.
- (For expansion cohort only): Tissue must be available to confirm positive expression of AG7 antigen, defined as proportional score ≥2, via slides or tumor block from either original diagnostic biopsy material or biopsy of relapsed disease
- Measurable disease by RECIST 1.1 criteria
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1.
- Adequate organ function within 3 weeks prior to first study drug administration as evidenced by:
- Absolute neutrophil count ≥1.5 x 109/L,
- Hemoglobin ≥9 g/dL,
- Platelet count ≥100 x 109/L,
- Serum creatinine ≤1.5 x upper limit of normal (ULN) or a calculated creatinine clearance >60 mL/min,
- Total bilirubin <1.5 x ULN, except for patients with Gilbert's disease who are eligible if total bilirubin ≤ 3mg/dL.
- Aspartate aminotransferase (AST)/serum glutamic-oxalacetic transaminase (SGOT)and alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT)<2.5 x ULN, or, in the presence of documented liver metastases, ≤5 x ULN.
- Ability to adhere to dose and visit schedules.
- Women of childbearing potential (WOCP) must have a negative pregnancy test result prior to enrollment. WOCP and men whose partners are WOCP must agree to use a highly effective method of birth control during the study and for 6 months following the last dose of study drug. A highly effective method of birth control is defined as one which results in a low failure rate (less than 1% per year).
- Ability to provide written informed consent
- . Life expectancy of at least 3 months.
You CAN'T join if...
- Any persistent, unresolved Common Terminology Criteria for Adverse Events (CTCAE)Grade ≥2 drug-related toxicity (except alopecia, erectile impotence, tinnitus, hot flashes, and loss of libido) associated with previous treatment. Inclusion of patients with persistent neuropathy or hearing loss Grade ≥2 due to previous treatment requires discussion with the sponsor.
- Radiation therapy within 2 weeks prior to first study drug administration.
- Major surgery within 3 weeks prior to first study drug administration.
- Any chemotherapy within 30 days of enrollment.
- Participation in any other clinical study with a potentially therapeutic agent or receipt of another investigational product within 21 days or 5 plasma half-lives,whichever is longer, prior to first day of drug administration (Day 1).
- Active central nervous system metastases. Patients with a history of brain metastases 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.
- Known human immunodeficiency virus (HIV) infection or a known HIV-related malignancy.
Note: HIV testing is not required unless there is any clinical suspicion that the patient might be HIV positive.
- Known active hepatitis B or C. HBV and HCV tests are required prior to Day 1.
- 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.
