| Eligibility |
Inclusion Criteria:
1. Histologically or cytologically confirmed unresectable, advanced/metastatic disease
pancreatic cancer that has progressed on standard first-line (or second- or later
line) systemic therapy (excepting progression within 6 months of end of adjuvant
systemic chemotherapy); or that can no longer be treated with first-line systemic
therapy due to subject's intolerance.
2. For dose escalation phase (Phase 1b), distant metastatic disease or advanced disease
and not a candidate for down staging to resection For expansion phase (Phase 2),
distant metastatic disease only
3. Prior radiation is allowed if the index lesion(s) remains outside of the treatment
field or has progressed since prior treatment. Radiation therapy must have been
completed at least 4 weeks prior to the baseline scan.
4. Age > 18 years
5. A life expectancy of at least 12 weeks
6. Laboratory tests performed within 14 days of treatment start:
1. Absolute neutrophil count (AGC/ANC) = 1,500/µL (=1.5 × 109/L)
2. Platelets = 100,000/µL (= 100 × 109/L) [Subjects may be transfused not more than
1 unit of platelets within 2 weeks to meet this requirement]
3. Hemoglobin = 9 g/dL (>90g/L) [Subjects may be transfused not more than 2 units of
pRBCs within 2 weeks to meet this requirement]
4. Calculated glomerular filtration rate (GFR)* >40 mL/min OR serum creatinine = 1.5
× ULN
5. Total bilirubin = 2.0 × ULN or = 3.0 × ULN for subjects with Gilbert's syndrome
6. AST, ALT, ALP = 2.5 × ULN or = 5.0 × ULN if liver metastasis present *using the
following Cockcroft & Gault equation to calculate the eGFR for this study.
eGFR in mL/min = [(140-age in years) × (weight in kg) × F]/(serum creatinine in mg/dL
× 72), where F =1 if male; and 0.85 for female.
7. Adequate pulmonary function with PFTs > 50% FEV1 if symptomatic or prior known
impairment
8. Negative serum pregnancy test within 14 days of treatment start if female and of
childbearing potential (non-childbearing is defined as greater than one year
postmenopausal or surgically sterilized)
9. Female subjects of childbearing potential must adhere to using a medically accepted
method of birth control prior to screening and agree to continue its use for at least
28 days after the last dose of HCW9218 or be surgically sterilized (e.g., hysterectomy
or tubal ligation) and males must agree to use a barrier method of birth control and
agree to continue its use for at least 28 days after the last dose of HCW9218
10. Provide signed informed consent and HIPAA authorization and agree to comply with all
protocol-specified procedures and follow-up evaluations
Exclusion Criteria:
Subjects with ANY of the following criteria are excluded from participation in the study
(to be verified by Sponsor prior to subject enrollment):
1. History of clinically significant vascular disease, including any of the following
within 6 months prior to start of study treatment: MI or unstable angina, percutaneous
coronary intervention, bypass grafting, ventricular arrhythmia requiring medication,
stroke or transient ischemic attack, symptomatic peripheral arterial disease
2. Marked baseline prolongation of QT/QTc interval (e.g., demonstration of a QTc interval
greater than or equal to 470 milliseconds by Fridericia's correction)
3. Subjects with untreated CNS metastases are excluded. Subjects are eligible if CNS
metastases are treated and subjects are neurologically stable for at least 2 weeks
prior to enrollment. In addition, subjects must be either off corticosteroids, or on a
stable or decreasing dose of = 10 mg daily prednisone (or equivalent)
4. Anti-cancer treatment including surgery, radiotherapy, chemotherapy, other
immunotherapy, or investigational therapy within 14 days before treatment start
5. Other prior malignancy except for the following: adequately treated basal cell or
squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II
cancer from which the subject is currently in complete remission, or any other cancer
from which the subject has been disease-free for 3 years after surgical treatment
6. Known hypersensitivity or history of allergic reactions attributed to compounds of
similar chemical or biologic composition to the agents used in the study
7. Prior therapy with TGF-ß antagonist, IL-15 or analogs
8. Concurrent herbal or unconventional therapy (e.g., St. John's Wort)
9. Known autoimmune disease requiring active treatment. Subjects s with a condition
requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone
equivalent) or other immunosuppressive medications within 14 days of enrollment.
Inhaled or topical steroids, and adrenal replacement steroid doses = 10 mg daily
prednisone equivalent, are permitted in the absence of active autoimmune disease
10. Active systemic infection requiring parenteral antibiotic therapy. All prior
infections must have resolved following optimal therapy.
11. Prior organ allograft or allogeneic transplantation
12. Known HIV-positive or AIDS
13. Women who are pregnant or nursing
14. Any ongoing toxicity from prior anti-cancer treatment that, in the judgment of the
Investigator, may interfere with study treatment. All toxicities attributed to prior
anti-cancer therapy other than peripheral neuropathy, alopecia, and fatigue must
resolve to grade 1 (NCI CTCAE v5.0) or baseline before administration of the study
treatment
15. Psychiatric illness/social situations that would limit compliance with study
requirements
16. Other illness or a medical issue that in the opinion of the Investigator would exclude
the subject from participating in this study
