| Eligibility |
Inclusion Criteria:
1. Female or male, age = 18 years old
2. Subject has cytological, histological, or pathological confirmation of pancreatic
cancer Note: All histologic subtype(s) of exocrine and endocrine pancreatic cancer are
eligible to enroll in the study
3. Borderline resectable or unresectable pancreatic cancer judged by the PI in
consultation with the designated site radiologist and surgeon at the treating
institution Borderline resectable tumors are those that have:
1. no distant metastases;
2. venous involvement of the superior mesenteric vein (SMV)/portal vein (PV) with or
without impingement and narrowing of the lumen;
3. short segment venous occlusion but with suitable vessel proximal and distal to
occlusion, allowing for safe resection and reconstruction;
4. gastroduodenal artery (GDA) encasement up to the hepatic artery (HA) with either
short segment encasement or direct abutment of HA, without extension to the
celiac axis (CA); and
5. tumor abutment of the SMA not to exceed 180° of the circumference.
Unresectable tumors are those that have:
1. Arterial:
Head/uncinate process:
- Solid tumor contact with SMA >180°
- Solid tumor contact with the CA >180°
Body and tail:
- Solid tumor contact of >180° with the SMA or CA
- Solid tumor contact with the CA and aortic involvement
2. Venous
Head/uncinate process:
- Unreconstructible SMV/PV due to tumor involvement or occlusion (can be due to
tumor or bland thrombus)
- Contact with most proximal draining jejunal branch into SMV
Body and tail:
• Unreconstructible SMV/PV due to tumor involvement or occlusion (can be due to tumor
or bland thrombus)
4. Subjects have an ECOG performance status = 1
5. Subjects who are eligible and able to participate in the study and accept to enter the
study by signing written informed consent forms
6. Patients are recovered from toxicities from prior systemic therapies to CTCAE grade 0
or 1 (alopecia = Grade 2 can enroll) and have adequate hematopoietic, liver and renal
function at screening and before using study medication
- Haemoglobin = 8 g/dL
- Absolute neutrophil count (ANC) = 1,500 cells/mm3
- Absolute lymphocyte count = 1000/mm3,
- Platelets = 100,000 /mm3
- Total white blood cell (WBC) = 3,000 cells /mm3
- Coagulation tests (prothrombin time [PT], activated partial thromboplastin time
[APTT], International Normalized Ratio [INR]) < 1.5×ULN,
- Total bilirubin = 1.5×ULN,
- Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase(SGOT) or
Alanineaminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) = 3 x
ULN
- Estimated Glomerular Filtration Rate (GFR) = 60 mL/min (MDRD method)
Glomerular Filtration Rate (GFR) is calculated using the MDRD formula:
GFR = 175 x (Standardized SCr)-1.154 x (age)-0.203 x (0.742 if female) x (1.210 if
African American)
7. The subject agrees not to use food supplementary or dietary that contains Angelica
sinensis after Screening Visit to Day 21.
8. All male subjects and female subjects with child-bearing potential (between puberty
and 2 years after menopause) should use appropriate contraception method(s) for at
least 4 weeks after EF-009 treatment shown below.
- Total abstinence (when this is in line with the preferred and usual lifestyle of
the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal,
post-ovulation methods) and withdrawal are not acceptable methods of
contraception).
- Female sterilization (have had surgical bilateral oophorectomy with or without
hysterectomy) or tubal ligation at least six weeks before taking study treatment.
In case of oophorectomy alone, only when the reproductive status of the woman has
been confirmed by follow up hormone level assessment.
- Male sterilization (at least 6 months prior to screening). For female subjects on
the study, the vasectomized male partner should be the sole partner for that
subject
- Combination of any two of the following (a+b or a+c, or b+c):
1. Use of oral, injected or implanted hormonal methods of contraception or
other forms of hormonal contraception that have comparable efficacy (failure
rate <1%), for example hormone vaginal ring or transdermal hormone
contraception.
2. Placement of an intrauterine device (IUD) or intrauterine system (IUS).
3. Barrier methods of contraception: Condom or occlusive cap (diaphragm or
cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal
suppository.
Exclusion Criteria:
1. Subjects who have participated in other investigational studies within 4 weeks prior
to receive EF-009
2. Subjects with known or suspected hypersensitivity to EF-009 or the excipient
3. Subject not eligible for resection without significantly affecting vital function
4. Subjects with distant metastasis or recurrence of pancreatic cancer
5. Patient has other severe and/or life-threatening disease(s) with life expectancy less
than 12 months
6. Subjects who have an immuno-compromised condition, or is with known autoimmune
conditions or is human immunodeficiency virus (HIV) seropositive.
7. Subjects with medical, social or psychological factors interfering with compliance of
the study
8. Subjects that have on-going moderate to severe organ impairment, other than the study
indication, that may confound the efficacy evaluation, safety evaluation or usage of
standard chemotherapy
9. Female subjects that are lactating, pregnant, or planned to become pregnant
