BATs Treatment for Pancreatic Cancer, Phase Ib/II
Phase Ib/II Treatment of Advanced Pancreatic Cancer With Anti-CD3 x Anti-EGFR-Bispecific Antibody Armed Activated T-Cells (BATs)
Study Overview
Status
Intervention / Treatment
Detailed Description
Once subjects are determined eligible, white blood cells (lymphocytes) are collected via leukapheresis procedure at approximately 3 to 4 weeks prior to first EGFR-BATs infusion. The white blood cells, specifically T cells, are then mixed with two proteins - OKT3 and IL-2 which activates the cells to multiply. After approximately 14 days in culture, the activated T cells are coated with the OKT3 and cetuximab to produce bispecific antibody armed T cells (BATs). Cells are then frozen and stored until scheduled to be infused.
Within one to two weeks prior to infusion of the study treatment, subjects will receive one dose of chemotherapy. The choice of chemotherapy agent(s) is at the discretion of the treating physician.
At approximately 4 weeks following leukapheresis procedure, twice weekly or weekly infusions of the BATs cells will take place (twice weekly for participants enrolled before DATE and weekly for participants enrolled after DATE). A total of eight twice weekly infusions or four weekly infusions will be given over a four week period. Please note that the weekly dose for both groups of participants is the same; participants that received twice weekly dosing received half of the weekly dose at each infusion.
Follow-up appointment schedule will include clinic visits at 1 to 2 weeks, 4 to 5 weeks, 2 months, 4 months and 6 months following the last infusion of BATs cells.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers

Demonstrate adequate hepatic, renal, and bone marrow function as defined below; all hematological, renal, and hepatic screening labs should be performed within 10 days prior to "on study" status (alpha gal testing must be within the regular screening period).
- Absolute lymphocyte count ≥ 400/mm3
- Absolute neutrophil count (ANC) ≥ 1,000/mm3
- Platelets ≥ 75,000/mm3
- Hemoglobin ≥ 8 g/dL
- Serum creatinine OR Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) < 2.0 mg/dl OR ≥50 ml/mm
- Serum total bilirubin ≤ 2 mg/dl (biliary stent is allowed)

Exclusion Criteria:
- Known hypersensitivity to cetuximab or other EGFR antibody
- Treatment with any investigational agent within 14 days prior to first study intervention (apheresis) for protocol therapy
- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to first study intervention (apheresis). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Serious non-healing wound, ulcer, bone fracture, major surgical procedure, open biopsy or significant traumatic injury within 28 days prior to "on-study" status
- Active liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis
- Is HIV positive or has evidence of active Hepatitis C virus or active Hepatitis B virus. If initial Hepatitis C test shows a positive result, the patient should have a Hepatitis viral load test to confirm. If initial HIV or Hepatitis B virus testing shows a positive result, no further testing will be done.
- Active bleeding or a pathological condition that is associated with a high risk of bleeding (therapeutic anticoagulation is allowed)
- Has an active infection requiring systemic therapy
- A serious uncontrolled medical disorder that in the opinion of the Investigator may be jeopardized by the treatment with protocol therapy
- Has a known history of active TB (Bacillus Tuberculosis)
- Has had prior chemotherapy, radiation, hormonal, monoclonal antibody (mAb) or targeted small molecule therapy, within 2 weeks prior to the first study procedure (apheresis). Subjects who have not recovered to <Grade 3 from an adverse event due to a previously administered agent are not eligible.
- Has received a live vaccine within 30 days of first study procedure (apheresis).
- History of a recent myocardial infarction (within one year), a past myocardial infarction (more than one year ago) along with current coronary symptoms requiring medications.
Has history of another malignancy within the past 5 years. Exceptions include
- basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy
- in situ cervical cancer.
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
- Females must not be breastfeeding
- Pt may be excluded if, in the opinion of the PI and investigator team, the pt is not capable of being compliant

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: EGFR BATs after standard of care chemo
Subjects will undergo apheresis to collect peripheral blood mononuclear cells.
Cells will be cultured for up to 2 weeks before activated T-cells will be harvested, armed with EGFR Biarmed activated T-cells, washed to remove unbound EGFRBi, and cryopreserved.
Subjects will then receive one dose of standard of care chemotherapy prior to receiving EGFR BATs.
|
Subjects will receive one dose of standard of care chemotherapy prior to twice weekly or weekly infusions of EGFR BATs for 4 weeks.

Time Frame |
---|---|---|
Incidence of adverse events
Time Frame: From the beginning of treatment (bridging chemotherapy) until no sooner than 30 days following the last study treatment
|
Safety will be assessed by incidence and severity of adverse events, changes in laboratory findings, physical examinations, vital signs, and the number of dose limiting toxicities and other discontinuations due to adverse events.
|
From the beginning of treatment (bridging chemotherapy) until no sooner than 30 days following the last study treatment
|
Overall survival
Time Frame: Until subject's death or study closure (whichever occurs first) for an average of 36 months from study treatment completion
|
An improvement in median overall survival (OS), defined as an increase from historical data of 8.7 months to 18.0 months.
|
Until subject's death or study closure (whichever occurs first) for an average of 36 months from study treatment completion
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cellular or humoral anti-pancreatic cancer responses
Time Frame: Every 2-6 months after the last EGFR BATs infusion for as long as the response lasts -- an average of 4 months
|
These will be measured in peripheral blood mononuclear cells
|
Every 2-6 months after the last EGFR BATs infusion for as long as the response lasts -- an average of 4 months
|
Clinical Efficacy
Time Frame: Imaging will be performed prior to treatment, 2 months after the last BATs infusion, then according to standard of care for an average of 12 months
|
Progression-free survival, measured by immune-related response criteria (irRC)
|
Imaging will be performed prior to treatment, 2 months after the last BATs infusion, then according to standard of care for an average of 12 months
|
Examine tumor tissue for immune system cells, cytokines and proteins to estimate whether the type and number of immune cells correlates with clinical responses

|
These immune system cells, cytokines and proteins include CD3, CD4, CD8, PD1/PDL1, monocytes subpopulations, MDSCs, and cytoplasmic IFN-y, tumor infiltrating lymphocytes, and IL-10.
This will be measured using immunohistochemical staining to quantitate type and number of immune system cells, cytokines, and proteins to estimate whether the type and number correlate with clinical responses.
